Hugo and Koby are measuring the heights of plants in biology class.

Use the drop-down menus to complete the statements about the measured heights and the actual heights of the plants.

The measure of m∠KPN is 68°.

Step-by-step explanation:

From the given diagram, we are given with lines passing through a point P creating different angles.

Data given,

m∠KPN = 4x°.

m∠NPO = (x+5)°.

And m∠KPO= 90°.

The m∠KPO is spitted into m∠KPN and m∠NPO.

Thus the sum of m∠KPN and m∠NPO will be m∠KPO.

⇒m∠KPN + m∠NPO =m∠KPO.

Substitute the values to find x value.

4x°+(x+5)°= 90°.

(°5x+5)=90°.

5x°=90°-5°.

5x°=85°.

x=[tex](\frac{85}{5} )[/tex].

x= 17.

⇒m∠KPN = 4x°.

=4(17)°.

m∠KPN =68°.

Thus the measure of m∠KPN is 68°.

Step-by-step explanation:

Tessa's account balance is $-15.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that Tessa had $90 in her checking account. She paid her cable/internet bill for $75.She deposited $50 from her part-time job before writing a check for $80 to pay her credit card bill.

The remaining amount is calculated as:-

Balance = 90 + 50 - 75 -80

Balance = $-15

Hence, the account balance is $-15.

The expression for the new function (fog(x)) = x⁸ + 8x⁴

What is a composite function?

A composite function some called function of a function is a process whereby two functions produce a third function.

Let assume there is a function f(x) and g(x), a composite function fog(x) read  as f of g of x, produces a third function h(x).

In the given question, we are to find (fog) (x), we will replace the value of the function g(x) for x in f(x).

i.e.

f(g(x) = x² + 8x  

[tex]f(g(x) = (x^4)^2+8(x^4)[/tex]

[tex]f(g(x)) = x^8+8x^4[/tex]

the correct answer is d

Step-by-step explanation:

The Area of rectangle is 30 sq. unit.

The distance between two points A( a,b) and B(c, d) in coordinate plane is

D= √(c- a)² + (d- b)²

Given:

From the figure the coordinates of rectangle are A(3, 8), B(6, 11), C(11, 6) and D(8, 3).

Using Distance Formula

length: l = √(8-3)² + (3-8)² = √25 + 25 = √50

width: w= √(6-3)² + (11- 8)² = √9+9 = √18

So, the area of rectangle = l x w

                                          = √50 x √18

                                          = √50 x √18

                                          = √900

                                          = 30 sq. unit.

We have,

[tex]\dfrac{6}{7} \times 42.21[/tex]

To find, the value of [tex]\dfrac{6}{7} \times 42.21[/tex] = ?

∴ [tex]\dfrac{6}{7} \times 42.21[/tex]

= [tex]\dfrac{6}{7} \times \dfrac{4221}{100}[/tex]

We know that,

The properties of rational numbers,

[tex]\dfrac{a}{b} \times \dfrac{c}{d} =\dfrac{a\times c}{b\times d}[/tex]

= [tex]\dfrac{6\times 4221}{7\times 100}[/tex]

= [tex]\dfrac{25326}{700}[/tex]

= 36.18

Thus, the value of [tex]\dfrac{6}{7} \times 42.21[/tex]= 36.18

First write 18% as a decimal by moving the decimal point two places to the left to get .18.

The word "of" means multiply, so we have (.18)(75) which is 13.5.

Answer:

13.5

Step-by-step explanation:

18% of 75

18% /100% x 75

0.18 x 75

13.5

To solve this, you need to isolate/get the variable "c" by itself in the equation:

4c + 8c = -55 + 3c    You can first combine like terms (4c and 8c)

12c = -55 + 3c         Subtract 3c on both sides

9c = -55       Divide 9 on both sides

Answer:

52 / 27

Step-by-step explanation:

To multiply mixed numbers, convert them into improper fractions. Multiply the two improper fractions together and simplify the result.

To multiply mixed numbers, we first convert them into improper fractions. To convert 1 1/3 into an improper fraction, we multiply the whole number (1) by the denominator (3) and add the numerator (1). This gives us 4/3. Similarly, to convert 1 4/9 into an improper fraction, we multiply the whole number (1) by the denominator (9) and add the numerator (4). This gives us 13/9.

Now, we can multiply the two improper fractions together. 1 1/3 times 1 4/9 equals (4/3) * (13/9). To multiply fractions, we multiply the numerators together and multiply the denominators together. So, (4/3) * (13/9) equals (4 * 13) / (3 * 9), which simplifies to 52/27.

Therefore, 1 1/3 times 1 4/9 in fraction form is equal to 52/27.

The variable 'a' in Albin's equation represents the number of minutes Albin was late for picking up from the daycare, with 3 dollars as the base fee and 0.50 dollars charged for each minute late.

The variable a in Albin's equation, 10.50 = 0.50a + 3, represents the number of minutes of Albin's late pick-up from the daycare. The base fee of the daycare is 3 dollars, which is a fixed amount, while 0.50 dollars is the rate charged per minute for being late. The equation is a way to calculate the total fee based on the minutes Albin is late.

For comparison, if we look at Aaron's Word Processing Service, the total cost of services would be represented by y = 31.50 + 32x, where 31.50 is a fixed cost and the cost for word processing is 32 dollars per hour (x). Similarly, for Svetlana's tutoring sessions, the total income she earns is given by y = 25 + 15x, where 25 is a one-time fee and 15 dollars per hour is her rate of earning.

The simplified expression is x^2 - 14xy + 49y^2.

To multiply the expression (x - 7y)^2 using the Special Product Formula, we can use the formula (a - b)^2 = a^2 - 2ab + b^2.

In this case, a = x and b = 7y. Plugging these values into the formula, we get:

(x - 7y)^2 = x^2 - 2(x)(7y) + (7y)^2

Simplifying further:

= x^2 - 14xy + 49y^2

So, the simplified expression is x^2 - 14xy + 49y^2.

Step-by-step explanation:

Answer:

$3.19

Step-by-step explanation:

so he starts with $18.90 and we know that he spent $2.95. So we will subtract  $2.95 from $18.90. So we are left with $15.95. But now its says he bought 5 items with $15.95. So we will divide 15.95 by 5. So the price of the item that he bought 5 of is $3.19

If you are at a higher level you can use this method:

make and equation of: 5x + 2.95 = 18.90

with this you would subtract 2.95 and then divide by 5 just like we did above.

Answer:

d. 15.95

Step-by-step explanation:

So if one item cost $2.95 and he bought 5 other items that were the same price, we first have to subtract $2.95 from the total which is $18.90.

18.90 - 2.95 = 15.95

Now, to find the cost of the other five items we divide the amount of money left by 5.

15.95 / 5 = 3.19

So each of the other five items costs $3.19.

To find the total cost of the five items together, we multiply 3.19 by 5.

3.19 x 5 = 15.95

3(4x + 2)

= 3 . 2(2x + 1)

= 6(2x + 1)

proof

• 3(4x + 2)

= 3(4(2) + 2)

= 30

• 6(2x + 1)

= 6(2(2) + 1)

= 30

Here is a similar question:

A bakery uses 10 1/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake.

The unit rate in ounces of icing per cake = 40 4/5 ounces

Step-by-step explanation:

Given:

Ounces of ice used for every 1/4 cake = 10 1/5

We have to find the unit rate.

Let the unit rate be 'x' .

Unit rate is the rate when we use unit 'one' as our reference to find any value.

Lets convert the mixed fraction of ounces.

⇒ [tex]10\frac{1}{5} = \frac{(10\times 5)+1}{5} =\frac{51}{5}[/tex]

Portion of the cake used = [tex]\frac{1}{4}[/tex]

To find the unit rate here we must divide :

⇒ [tex]x=\frac{number\ of\ ounces\ used}{portion\ of\ the\ cake}[/tex]

⇒ [tex]x=[/tex] [tex]\frac{51}{5}[/tex]  ÷  [tex]\frac{1}{4}[/tex]

⇒ [tex]x=[/tex] [tex]\frac{51}{5}\times \frac{4}{1}[/tex]

⇒ [tex]x=[/tex] [tex]\frac{51\times 4}{5}[/tex]

⇒ [tex]x=[/tex] [tex]\frac{204}{5}[/tex]

⇒ [tex]x=[/tex] [tex]40\frac{4}{5}[/tex]  Or [tex]40.8[/tex]  

Hence, the unit rate in ounces of icing per cake = 40 4/5 ounces.

∵ Each input has only one output

∵ In the function each input has only one output

∴ The relation is a function

7/8 probability means that it is likely

Step-by-step explanation:

7/8 probability means that it is likely because 8/8 would mean certain. The closer the number gets to 8/8, the more likely it becomes. The farther away it goes, the less likely it becomes. Also, because half of 8 is 4, if the number on top is anything over 4, it means the chance is likely. If it's under 4, it's unlikely. And if it's exactly 4, then that means it is a 1/2 chance like flipping a coin.
