The length of MG is 56 for the given similar triangles.

Step-by-step explanation:

Let us consider EML and EGF is two similar triangles.

From the triangle,

EG=5x+2.

EM=16.

EL=28.

EF=126.

According to similar triangle property,

triangle ratio= [tex]\frac{EM}{EG} =\frac{EL}{EF} =\frac{ML}{GF} .[/tex]

[tex]\frac{16}{5x+2}=\frac{28}{126}[/tex].

126(16)=28(5x+2).

2016=140x+56.

140x=1960.

x=14.

⇒EG=5(14)+2.

EG=70+2.

EG=72.

To find the length of MG,

EG=EM+MG.

MG=EG-EM.

=72-16.

MG=56.

The question, asking for the length of a segment within a triangle, belongs to the field of Mathematics and is most likely at a High School level. However, based on the given information, an exact answer cannot be provided.

Unfortunately, the provided information is not sufficient enough to find the length of MG. The relationship EGF ~ EML indicates that the triangles EGF and EML are similar, meaning their corresponding sides are proportional. To find the length of MG (a segment within triangle EML), we would typically use a known length from triangle EGF and the scale factor between the two triangles. However, without these additional specifics, we cannot provide an exact value for the length of MG.

Answer:

probability is 671 out of 1296 or 51.8 %.

Step-by-step explanation:

When we roll 4 fair 6-sided dice total outcomes are

 6^4 = 1296

The outcomes where no dice show greater than 5, the dice can show numbers 0,1,2,3,4,5

So the no of these outcomes where no dice show greater than 5 can be found by

5^4 = 625

No of outcomes where at least one dice will show number greater than 5 are

1296-625 = 671

Or in percentage,the probability is (671/1296)*100 = 51.8%

Step-by-step explanation:

To find the angle of elevation of the sun, we use the tangent function with the height of the flagpole and the length of the shadow. Calculating the arctangent of the ratio of the height to the shadow length and converting it to degrees gives us the angle of elevation.

The question asks about the angle of elevation of the sun when casting the shortest shadow of a flagpole. We can use trigonometric functions to find this angle using the height of the flagpole and the length of the shadow. The height of the flagpole is 282 ft and the length of the shadow is 137 ft.

To find the angle of elevation (θ), we use the tangent function, which is the ratio of the opposite side (height of the flagpole) to the adjacent side (length of the shadow). So, tangent(θ) = opposite/adjacent = 282 ft / 137 ft.

Now, we will calculate the angle using the inverse of the tangent function, also known as arctangent.

θ = arctan(282/137)

To find the angle in degrees, we use a calculator to compute arctan(282/137). After computing, we round the result to the nearest whole number to find the angle of elevation to the nearest degree.

Answer: the length of the arc is 15.17π feet

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 13 feet

θ = 210 degrees

Therefore,

Length of arc = 210/360 × 2 × π × 13

Length of arc = 15.167π feet

rounding up to 2 decimal places, it becomes

15.17π feet

Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.

3 x 10 = 30

The unknown dimension is 30

Answer:A randomization

Step-by-step explanation:Randomization in scientific experiments is a sampling method in which the participants or researchers are chosen randomly and assigned a treatment.

Here the participants or researchers do not know for sure which treatment is better.

Randomization reduces any possible bias responses to a minimal.

Answer:

1) The possible outcomes 2) Quantitative 3) The explanation to those outcome 4) Qualitative

Step-by-step explanation:

1) The response variable is a measurable variable, i.e. also called the dependent variable. In the study, they will represent the possible outcome.

E.g.

Suppose the study "Practicing enhances technique", the amount of hours will be the response variable.

2) Is the response variable qualitative or​ quantitative? Since it is measured, it's a quantitative.

In our example, our response variable would be hours, how many hours is necessary to display some enhancement?

3) What is the explanatory​ variable?

The explanatory ones, or also independent variables offer explanations to the results the response variables have shown.

In our example, the level of training (low, mid, hard) would be the explanatory one.

4) Is the explanatory variable qualitative or​ quantitative?

In our example, the explanatory response or independent one is qualitative since to classify the training as low, middle or harder is to classify them as categorical then it's qualitative.

Now we know that;

In 90 seconds = 135 multiplication facts.

So in 1 second = Number of fact answered in 1 second

Answer:

Step-by-step explanation:

Assuming the rate of increase in the cost of tuition fee per year is linear. We would apply the formula for determining the nth term of an arithmetic sequence which is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = $20500(amount in 2000)

From 2000 to 2018, the number of terms is 19, hence,

n = 19

T19 = 454120

Therefore,

454120 = 20500 + (19 - 1)d

454120 - 20500 = 18d

18d = 433620

d = 433620/18

d = 24090

Therefore, the equation that can be used to find the tuition y for x years after 2000 is expressed as

y = 20500 + 24090(x - 1)

To to estimate the tuition at this college in 2020, the number of terms between 2000 and 2020 is 21, hence

x = 21

y = 20500 + 24090(21 - 1)

y = 20500 + 481800

y = $502300

Using linear interpolation, the yearly increase of tuition was calculated and an equation was formed. Substituting the year 2020 into the equation gave an estimated tuition of $47,855.60.

To write an equation that represents the tuition cost y for x years after 2000, we use two given data points: in 2000, tuition was $20,500 (which means when x=0, y=$20,500), and in 2018, tuition was $45,120 (when x=18, y=$45,120). To find the rate of change, we calculate the slope by finding the difference in tuition and dividing it by the difference in years:

Slope (m) = (Y2 - Y1) / (X2 - X1) = ($45,120 - $20,500) / (18 - 0) = $24,620 / 18 ≈ $1,367.78

Now we can write the equation of the line in slope-intercept form (y = mx + b), where b is the initial tuition in the year 2000:

Equation: y = 1367.78x + 20,500

To estimate the tuition in 2020, set x to 20:

y = 1367.78(20) + 20,500 = $27,355.60 + 20,500 = $47,855.60

Therefore, the estimated tuition in 2020 is $47,855.60.

Step-by-step explanation:

Hi,

A simple way to look at this is making the pattern:

Red, Yellow

Red, Yellow, Blue

Red, Yellow, Blue, Green

Red, Yellow, Blue, Green, Pink

Red, Yellow, Blue, Green, Pink, Orange

Red, Yellow, Blue, Green, Pink, Orange, Purple

Red, Yellow, Blue, Green, Pink, Orange, Purple, White

2 + 3 + 4 + 5 + 6 + 7 + 8 = 35

You can otherwise use the Carl Gauss's formula for calculating the sum of increasing consecutive number:

[tex]Sum = \frac{n}{2} \ (a + b)[/tex]

where: n is the total number of rows;

a is the starting number of values and b is the ending number.

Hence, in this case:

n = 7

a = 2

b = 8

[tex]Total\ number\ of\ candles\ = \frac{7}{2}\ (2+8)\\ =35[/tex]

Final answer:

By analyzing the color pattern, which adds one new color each step and concludes with white being the eighth color, there are 8 total candles on the cake.

Explanation:

To determine how many total candles are on the cake with a color pattern that grows and ends with a white candle, we must first recognize the sequence of colors added as the pattern progresses. The given pattern is red, yellow; red, yellow, blue; red, yellow, blue, green, and continues adding in the order of pink, orange, purple, and finally white.

By this sequence, we can see that the color white will be the last in a set of eight candles (red, yellow, blue, green, pink, orange, purple, white). Since we are looking for the point at which the last candle is white, this indicates that the full sequence has been completed one time entirely. Therefore, there are 8 total candles on the cake.

Answer:

Fred used 8 roses to make the bouquet.

Step-by-step explanation:

Let 'x' roses be used to make a bouquet.

Given:

Cost of carnations = $5.25

Cost of 1 rose = $1.68

Total cost of the bouquet = $18.69

Cost of 1 rose = $1.68

Therefore, using unitary method, the cost of 'x' roses is given as:

Cost of 'x' roses = [tex]1.68x[/tex]

Now, as per question:

Cost of carnations + Cost of 'x' roses = Total cost of the bouquet

[tex]5.25+1.68x=18.69\\\\1.68x=18.69-5.25\\\\1.68x=13.44\\\\x=\frac{13.44}{1.68}\\\\x=8[/tex]

Therefore, Fred used 8 roses to make the bouquet.

Fred used 8 roses in the bouquet.

To solve the problem, we need to find out how many roses Fred used, given the total cost of the bouquet and the cost of the carnations and each rose.

Let's denote the number of roses as ( r ).

The cost of one rose is $1.68. Therefore, the cost of ( r ) roses is ( 1.68r ).

The cost of the carnations is given as $5.25.

The total cost of the bouquet is $18.69.

We can set up the equation to represent the total cost of the bouquet as the sum of the cost of the carnations and the cost of the roses:

[tex]\[ 5.25 + 1.68r = 18.69 \][/tex]

Now, we need to solve for [tex]\( r \):[/tex]

Subtract $5.25 from both sides of the equation to isolate the term with [tex]\( r \):[/tex]

[tex]\[ 1.68r = 18.69 - 5.25 \][/tex]

[tex]\[ 1.68r = 13.44 \][/tex]

Next, divide both sides by $1.68 to solve for r :

[tex]\[ r = \frac{13.44}{1.68} \][/tex]

[tex]\[ r = 8 \][/tex]

Answer:

B=80 A=40 EFD=60 BCF=120

Step-by-step explanation:

First off chill. Second off B=80  A=40 EFD=60  BCF=120.  It is quite simple. The congruency marks give the first angle away and you solve from there. If you need help I would do more research because this is important for later units. Also the triangles are congruent.

Answer

Angle A = 40 degrees

Angle B = 80 degrees

Measure BCF = 120 degrees

Measure EFD = 60 degrees

Step-by-step explanation:

Angle A:

Ok, so we know angle A is congruent to angle D because of the line. If you make an equation out of it, you get 2x+20 = 3x+10. If you solve this equation:

2x + 20 = 3x + 10

20 = x+10

10 = x

you will get x=10. Plug it into the equation, and Angle A = 40 degrees.

Angle B:

The two lines that are both on angle B and E mean that they are congruent. We know that angle E = 80 degrees, so angle B does too.

Measure BCF:

We know that Angle A = 40 degrees, and angle B = 80 degrees. The degree sum of all angles in a triangle is 180 degrees.

80 + 40 = 120

180 - 120 = 60

So measure BCA = 60 degrees.

That angle is on a straight line. Two angles on a straight line add up to 180 degrees.

180 - 60 = 120.

So, Measure BCF = 120 degrees.

Measure EFD:

We already found measure BCA while finding measure BCF, and that is just congruent to EFD.

So, measure EFD = 60 degrees

Answer:

The answer to your question is x = 2.5

Step-by-step explanation:

We know that lines r and s are parallel so angles 1 and 2 are corresponding angles. Corresponding angles measure the same.

                                      m∠1 = m∠2

Substitution

                                40 - 4x = 50 - 8x

Solve for x

                               8x - 4x = 50 - 40

                                       4x = 10

                                         x = 10/4

                                         x = 2.5

The variable x is found to equal 3. Substituting x=3 into the expressions for JK and KL, both are found to equal 13. The entire line segment JL is then found to equal 26.

In this mathematics problem, we are given that K is the midpoint of JL. This implies that the segments JK and KL are of equal length, thus JK=KL.

So, we can set the two given expressions equal to each other: 2x+7=4x+1. Solving this equation for x, we get that x=3.

Substituting x=3 into the expressions for JK and KL: JK=2x+7=2(3)+7=13, and KL=4x+1=4(3)+1=13.

To find JL, we simply add JK and KL together, since JKL is a line segment with K being the midpoint. Hence, JL=JK+KL=13+13=26.

Answer: he got 297 cards in a year.

Step-by-step explanation:

There are 12 months in a year. Rashaads sister gives him 2 pack of cards per month. This means that in a year, his sister would give him

2 × 12 = 24 packs of cards.

If there are 11 cards in a pack, then the number of cards that his sister gives him in a year would be

24 × 11 = 264 cards.

He also gets 3 extra packs for his birthday. It means that the number of cards that he gets for his birthday would be

3 × 11 = 33 cards.

Therefore, the total number of cards that he gets in a year is

The surface area of the cone is [tex]266.9cm^2[/tex]

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

[tex]r=\frac{d}{2} =\frac{10}{2} =5[/tex]

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

[tex]$S A=\pi r^{2}+\pi r l$[/tex]

Substituting the values, we get,

[tex]$S A=(3.14)(5)^{2}+(3.14)(5)(12)$[/tex]

[tex]$S A=(3.14)25+(3.14)(60)$[/tex]

[tex]SA=78.5+188.4[/tex]

[tex]SA=266.9cm^2[/tex]

Thus, The surface area of the cone is [tex]266.9cm^2[/tex]

The surface area of the cone is approximately 268 square centimeters.

To find the surface area of a cone, we need to know the slant height and the radius of the base. The slant height is given as 12 centimeters. Since the diameter is 10 centimeters, we can find the radius by dividing the diameter by 2, which is 5 centimeters. Now we can use the formula for the surface area of a cone:

A = πr(r + l), where A is the surface area, r is the radius, and l is the slant height.

Plugging in the values, we get: A = 3.14 * 5(5 + 12) = 3.14 * 5 * 17 = 268.1 square centimeters. Rounding to the nearest whole number, the surface area of the cone is approximately 268 square centimeters.
