Answer 2

Answer:

x = 1/5

Step-by-step explanation:

To solve, simplify the equation, then isolate "x". Start with the distributive property, where you multiply the number outside the brackets with each number inside the bracket. Isolate "x" by bringing all the other numbers to the right side on the equal sign. When moving a number, do its reverse operation to the whole equation.

-5(x-3) = 14           Distribute. Multiply -5 by "x", subtract -5 times 3.

(-5)x - (-5)3 = 14           Multiply -5 and 3

(-5)x - (-15) = 14           Two negatives make a positive

(-5)x + 15 = 14           Remove brackets around -5

-5x + 15 = 14           Start isolating

-5x + 15 - 15 = 14  - 15          Subtract 15 from both sides

-5x = -1          Left side: 15 cancelled out.  Right side: 14-15 = -1

-5x/-5 = -1/-5          Divide both sides by -5.

x = 1/5         Solved for "x"

Check your answer by substituting "x" with the answer you found:

-5(x - 3) = 14  

-5(([tex]\frac{1}{5}[/tex]) - 3) = 14          Change "x" to 1/5.

-5(([tex]\frac{1}{5}[/tex]) - [tex](\frac{5}{5})(\frac{3}{1})[/tex]) = 14           Make 5 the common denominator

-5([tex]\frac{1}{5}[/tex] - [tex]\frac{15}{5}[/tex]) = 14          Multiply the fractions across

-5([tex]\frac{1-15}{5}[/tex]) = 14        Combined the fractions on top of the same denominator

-5([tex]-\frac{14}{5}[/tex]) = 14          Simplify numerator

[tex]\frac{-5*-14}{5}[/tex] = 14          Multiply by combining into the numerator

[tex]\frac{70}{5}[/tex] = 14          Divide the top by the bottom of the fraction

14 = 14             Same answer on both sides

LS = RS          Left side equals right side

Therefore the answer is correct.

A blue rope is three times as long as the red rope. A green rope is five times as long as the blue rope. If the total length is 508.25 meters, what is the length of the blue rope?

Answers

Answer:

The length of the blue rope is 80.25 meters.

Step-by-step explanation:

B = Blue Rope

G = Green Rope

R = Red Rope

B=3R (Blue is 3 x as long as Red)

G=5B (Green is 5 x as long as Blue)

B+G+R = 508.25 (The three ropes together are 508.25 meters)

Since B=3R, I will rewrite the equation above

3R + G + R = 508.25

Now, I will write G in terms of R:

G=5B

B=3R, so 5B = 15R (multiply both sides by 5) which means that G=5B=15R, so G=15R.

Rewrite the equation again in terms of R:

3R + 15R + R = 508.25

19R = 508.25 (combine like terms)

R = 26.75 (divide both sides by 19 to solve for R)

Now, use the value 26.75 (R, which is the length of the red rope) to solve for B (the length of the blue rope):

B=3R

B=3(26.75)

B=80.25 meters

Find the circumference of this figure. Show your calculations.

Answers

Answer:

Circumference of circle= 37.68 units

Circumference of sector= 6.28 units

Step-by-step explanation:

The given figure is a circle with given radius OB= 6 units.

The circumference of a circle is the total length of its boundary.

For the complete circle its circumference can be calculated by;

           Circumference= [tex]2\pi r[/tex]

                                 [tex]=2*3.14*6\\=37.68[/tex] units

For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:

So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.

What is the value of x?

Answers

Answer: x = 15

Step-by-step explanation: The first thing to note is that what we have here are two similar triangles. First we have triangle ABC and secondly we have triangle EDC. Line BD is a transversal that cuts line AE at point C. Hence we can deduce that angle ACB is equal in measurement to angle ECD (opposite angles). Next we also observe that the other two angles are right angles, that is, 90° in size. Therefore we can conclude that the other two angles (angle ABC and angle EDC) are also of the same measurement.

We can now establish the ratio of the similar sides.

Line AB = Line ED

Line AC = Line EC

AB/ED = AC/EC

24/40 = 2x/3x + 5

3/5 = 2x/3x + 5 {the left hand side has been reduced to it's simplest form}

Givena general quadratic equation

ax²+bx+c = 0

The general formula for finding x is;

x = -b±√b²-4ac/2a

Where a,b and c are the coefficient of x², x and x° respectively

Given the solution in question to be;

x = 5±2√7/3

The quadratic equation that has thw above general solution will be;

3x²-10x+6 = 0

From the equation, a = 3, b= -10 and c = 6

Substituting this value in the general formula to get x we have;

x = -(-10)±√(-10)²-4(3)(6)/2(3)

x = 10±√100-72/6

x = 10±√28/6

x = 10±√7×4/6

x = 10±2√7/6

Dividing through by 2 gave;

x = 2(5±2√7)/6

x = 5±2√7/3 (which gives the solution in question)

The answer should be 30,000. I just do not understand how to get to it.

Thank you in advance!

Answers

Answer:

Below is the procedure to find the answer: 30,000 hot dogs.

Explanation:

The average cost is found dividing the total cost by the number of hot dogs:

         [tex]Average\text{ }cost=Total\text{ }cost/Number\text{ }of\text{ }hot\text{ }dogs[/tex]

The total cost is the the sum of amount that you invest plus the product of the cost of producing each hot dog times the number of hot dogs:

[tex]Total\text{ }cost=investment+Number\text{ }of\text{ }hot\text{ }dogs\times cost\text{ }to\text{ }produce\text{ }each\text{ }hot\text{ }dog[/tex]

Substitute the values:

           [tex]Total\text{ }cost=15,000+0.65x\\ \\ Averate\text{ }cost=(15,000+0.65x)/x=1.15[/tex]

Where x is the number of hot dogs.

Solve for x from the equation:

         [tex](15,000+0.65x)/x=1.15\\ \\ 15,000+0.65x=1.15x\\ \\ 15,000=1.15x-0.65x\\ \\ 15,000=0.5x\\ \\ 15,000/0.5=x\\ \\ 30,000=x\\ \\ x=30,000[/tex]

Which shows you how you can find that the answer is 30,000 hot dogs.

Final answer:

To find the number of hot dogs needed to achieve an average cost of $1.15, including a fixed investment of $15,000 and a variable cost of $.65 per hot dog, the calculation reveals that 30,000 hot dogs must be sold to reach this target.

Explanation:

The question asks how many hot dogs must be sold before the average cost per hot dog is $1.15, given an initial investment of $15,000 and a production cost of $.65 per hot dog. To find the break-even point in terms of units sold to reach the target average cost, we use the formula to calculate average cost: Average Cost = (Fixed Costs + Variable Costs) / Quantity. Here, the fixed cost is the initial investment of $15,000, and the variable cost is $.65 per hot dog.

To find the number of hot dogs needed to achieve an average cost of $1.15, we set up the equation: $1.15 = ($15,000 + $.65Q) / Q. Solving for Q gives us 30,000 hot dogs as the break-even point where the average cost per hot dog would be $1.15.

This calculation allows the business owner to understand how many units need to be sold to overcome the initial investment and start making a profit on each hot dog sold at or above $1.15.

You have 8 gallons of lemonade to sell. You use cone-shaped cups that are 9 centimeters in diameter and 12 centimeters tall. Each customer uses one paper cup. How many paper cups will you need if you sell all of the lemonade? (1 gal ≈ 3785 cm3)

Answers

You will need 119 cups to sell all of the lemonade.

Step-by-step explanation:

Given,

Diameter of cups = 9 cm

Radius of cup = [tex]\frac{Diameter}{2}=\frac{9}{2}=4.5\ cm[/tex]

Height of cups = 12 cm

We will find volume of cup.

[tex]Volume = \frac{1}{3}\pi r^2h\\[/tex]

Putting all the values

[tex]Volume=\frac{1}{3}(3.14)(4.5)^2(12)\\\\Volume=\frac{1}{3}(3.14)(20.25)(12)\\\\Volume= \frac{763.02}{3}\\\\Volume= 254.34\ cm^3[/tex]

Therefore;

Each cup can hold 254.34 cubed centimeter of lemonade.

Number of gallons = 8

1 gallon = 3785 cm³

8 gallons = 3785*8 = 30280 cm³

Let,

x = Number of cups

Volume of lemonade in one cup * Number of cups = Volume of 8 gallons

254.34x=30280

Dividing both sides by 254.34

[tex]\frac{254.34x}{254.34}=\frac{30280}{254.34}\\x=119.05[/tex]

Rounding off to nearest whole number

x = 119

You will need 119 cups to sell all of the lemonade.

What are inequalities?

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Given that the perimeter of a rectangle must be less than 172 feet. Also, given that the length of the rectangle is 53 feet. Therefore, we can write inequality of the width of the rectangle as,

2(Length) + 2(Width) < Perimeter

2(53 feet) + 2(Width) < 172 feet

106 feet + 2(Width) < 172 feet

2(Width) < 172 feet - 106 feet

2(Width) < 66 feet

Width < 66feet / 2

Width < 33 feet

Correct Option is 4 and 5.

Let's assume "x" is the length of the tether ball pole shadow, and "y" is the length of the flagpole shadow.

According to the information given, the proportional relationship can be expressed as:

Tether ball pole height / Tether ball pole shadow length = Flagpole height / Flagpole shadow length

The height of the tether ball pole is 333 meters, and the height of the flagpole is 6.8 meters.

So, we have the following equation:

333 meters / x = 6.8 meters / y

Now, let's solve for "y" in each choice and check which choices satisfy the proportional relationship:

Choice A:

333 / 1.35 = 6.8 / 3.4

246.67 ≈ 2

Choice B:

333 / 1.8 = 6.8 / 4.08

185 ≈ 1.67

Choice C:

333 / 3.75 = 6.8 / 8.35

B(14 - b, 72).

Let us assume the points are in the order: AOB.

Since the line passes through all these points the slope of the line segment AO = The slope of the line segment AB.

Slope of a line with two points: [tex]$ \frac{y_2 - y_1}{x_2 - x_1} $[/tex]   where [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $[/tex] are the points given.

[tex]$ (x_1, y_1) = (0,0) $[/tex]

[tex]$ (x_2, y_2) = (-2, b - 14) $[/tex]

Therefore, the slope of the line segment AO = [tex]$ \frac{b - 14}{-2} $[/tex]

Similarly, for the slope of the line segment OB.

The two points are [tex]$ (x_1, y_1) = (0, 0) $[/tex] and [tex]$ (x_2, y_2) = (14 - b, 72) $[/tex].

The slope is:  [tex]$ \frac{72}{14 - b } $[/tex]

Since, the slopes are equal we can equate:

[tex]$ \frac{b - 14}{-2} = \frac{72}{14 - b} $[/tex]

[tex]$ \implies \frac{b - 14}{-2} = \frac{72}{-(b - 14)} $[/tex]

[tex]$ \implies (b - 14)^2 = 72 \times 2 = 144 $[/tex]

[tex]$ \implies (b - 14)^2 = 12^2 $[/tex]

Taking square root on both sides we get:

[tex]$ \implies (b - 14) = \pm 12 $[/tex]

[tex]$ \implies b = 2 \hspace{2mm} or \hspace{2mm} 26 $[/tex]

Therefore, the maximum value of b = 26.

Hence, the answer.

Of the 40 students in Ms. Carr's class, 87.5% live less than 10 miles from school. How many of the students in Ms. Carr's class live less than 10 miles from school.

Answers

Answer:

35

Step-by-step explanation:

Total number of students in class is 40

87.5% of the class = 87.5/100 *40 =35

The students in Ms. Carr's class that live less than 10 miles from school are 35 students.

To find out how many students in Ms. Carr's class live less than 10 miles from school, we can use the percentage provided in the question.

1. Identify the total number of students in the class:

  Ms. Carr has a total of 40 students in her class.  

2. Determine the percentage of students living less than 10 miles from school:

  We know that 87.5% of these students live less than 10 miles from school.  

3. Convert the percentage to a decimal for calculation:

To convert 87.5% to a decimal, we divide by 100:  

[tex]\[ 87.5\% = \frac{87.5}{100} = 0.875 \][/tex]

4. Calculate the number of students:  

Now, multiply the total number of students by the decimal:  

Number of students = 0.875 × 40 = 35

5. Conclusion:

Therefore, 35 students in Ms. Carr's class live less than 10 miles from school.

The width of a rectangular painting is 3in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting

Answers

Question:

A width of a rectangular painting is 3 in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting

a. write an expression for the combined area of the painting and frame.

b. use the expression to find the combined area when the height of the painting is 12 in.

c. use the expression to find the combined area when the height of the the painting is 15 in.

Answer:

a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame

b) The combined area when h = 12 is 544 square inches

c) The combined area when h = 15 is 760 square inches

Solution:

Given that,

A frame that is 2.5 inches wide goes around the painting

The frame will go around all 4 sides of the painting.

That means that the length of each side of the painting will increase by 2.5 inches

Therefore,

The height of painting and frame is:

h = h + 2.5 + 2.5

h = h + 5

(2.5  inches on the top and the bottom)

Also given that,

Width of a rectangular painting is 3 inches more than twice the height

w = 3 + 2h

Now the width of painting and frame is:

w = 3 + 2h + 2.5 + 2.5

(Again, 2.5 inches on the top and the bottom)

w = 2h + 8

Thus the combined area of the painting and frame is:

[tex]Combined\ area = (h+5)(2h+8)[/tex]

B) Substitute h = 12 inches

[tex]Combined\ area = (12+5)(2(12)+8)\\\\Combined\ area = 17 \times (24+8) = 17 \times 32\\\\Combined\ area = 544[/tex]

Thus the combined area when h = 12 is 544 square inches

C) Substitute h = 15 inches

[tex]Combined\ area = (15+5)(2(15)+8)\\\\Combined\ area = 20 \times (30+8) = 20 \times 38\\\\Combined\ area = 760[/tex]

Thus combined area when h = 15 is 760 square inches
