If a figure is dilated by a factor of 1.5, the area of the figure will change by a factor of

Answers

Answer:

The figure will change by a factor of 2.25.

Step-by-step explanation:

When the lengths (1-dimensional) change by a factor 1.5 (the definition of dilating a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.

the area of the figure will change by a factor of 2.25

10 Determine the area of the figure. 9 cm 6 cm 12 cm​

Answers

Answer:

Area= 648

Step-by-step explanation:

Area formula: L times W times H

9 times 6 times 12        :)

When the length, width, and the height is given so the area of the figure is considered to be 648.

Calculation of an area:

Since the length is 9cm

The width be 6 cm

And, the height is 12 cm

So, the area be like

= (9) (6) (12)

= 648

Hence, When the length, width, and the height is given so the area of the figure is considered to be 648.

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre of strawberry plants will yield 770 pounds of strawberries when 70 cubic feet of fertilizer are applied. If 90 cubic of feet of fertilizer are applied, the yield will be 990 pounds of strawberries. Use linear interpolation to estimate the yield if 72 cubic feet of fertilizer are applied.

______________(and select unit of meansure)---> (cubic feet/ pounds per cubic foot/ pounds/cubic feet per pound

Answer:

Step-by-step explanation:

[tex]x_1=70[/tex] cubic feet of fertilizer is used in [tex]y_1=770[/tex] pounds of strawberries

[tex]x_2=90[/tex] cubic feet of fertilizer is used in [tex]y_2=990[/tex] pounds of strawberries

Linear interpolation is applied

[tex]y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}[/tex]

Can anyone help I do t know how to find all seven angles

Answers

Answer:

1. 110

2. 70

3. 70

4. 110

5. 110

6. 70

7. 70

Step-by-step explanation:

when to lines cross, opposite angles are equal so like 1 and 4 are equal

1, 4, and 5 are equal to 110

to find 2, 3, 6, and 7, subtract 110 from 180

Step-by-step explanation:

110 is vertical from angle 5 so they are the same

180-110=70 degrees

Assume that y varies inversely
with x. Ify = 7 when x = 2/3, find
y when x = 7/3.

Y=?

Answers

Answer:

y = 2

Step-by-step explanation:

y varies inversely with x setup is:

y = k/x

7 = [tex]\frac{k}{2/3}[/tex]  (find 'k')

k = 7/1 · 2/3

k = 14/3

use what you know about 'k' and 'x' to solve for 'y'

y = 14/3 ÷ 7/3  (remember to multiply by the reciprocal when dividing fractions)

y = 14/3 · 3/7

y = 2

Determine the ratio in the picture below

Answers

Answer:

Sin Z=30/50 or 3/5

Step-by-step explanation:

To figure out Sin Z, you need the formula which is Sin=o/h

O=opposite

H=Hypotenuse

To find opposite, you locate the angle(angle Z) and you draw an arrow that is opposite of the angle. To find hypotenuse, you pinpoint the right angle and you find the degree that it is opposite of.

O=30

H=50

Finally, you simplify 30/50 to get 3/5ths. Hope this helps you out!

D. All Real Numbers

The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]

The range are the possible output values of f(x)

We need to solve f(x) = 3.2x for each value in our domain

f(-4) = 3.2(-4) = -12.8

f(-2) = 3.2(-2) = -6.4

f(0) = 3.2(0) = 0

f(2) = 3.2(2) = 6.4

f(4) = 3.2(4) = 12.8

-360 divided by -40 ?

Answers

Answer: 9

Step-by-step explanation:

The required -360 divided by -40 is equal to 9. The negative signs cancel out when dividing two negative numbers, resulting in a positive result.

When dividing two negative numbers, it's helpful to keep in mind the following rule:

The division of two negatives yields a positive result.

Now, let's perform the division:

-360 ÷ -40

Since both numbers are negative, we know the result will be positive.

Divide the absolute values of the numbers.

|-360| ÷ |-40| = 360 ÷ 40 = 9

Apply the rule for the division of two negatives.

Since both numbers are negative, the result will be positive:

-360 ÷ -40 = 9

Therefore, -360 divided by -40 is equal to 9.
