Answer:

The scale factor is 2.2

Step-by-step explanation:

To find the scale factor, you look at the length of any two sides that correspond to each other. For example, in the diagram we can see that the side with the length of 4 on the smaller pentagon corresponds to the side with the length of 8.8 on the larger pentagon.

To find the scale factor, you divide the length of the side of the larger pentagon, by the length of the side of the smaller pentagon.

$\frac{8.8}{4} = 2.2$

The scale factor is 2.2

Hope this helps!

The tent shown below has fabric covering all four sides and the floor. What is the minimum amount of fabric needed to construct

Answer:

I believe the answer is 152 ft

Step-by-step explanation:

On the side, you would find the area of the square (8x5=40). Then, you would find the area of the triangular front (6x4=24 divded by 2 so it's 12). There are two sides of each, so 24+80=104. Then, you dfind the aarea of the bottom square (6x8=48) and add them all together to make 152

Simplify x^3 y^3 / x^3 y^3

Marysya12 [62]

Answer:

$\frac{1}{y}$

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

$\frac{x*x*x*y*y*y}{x*x*x*y*y}$

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is $\frac{1}{y}$

Nathan's boy scout troop is making M&M and peanut trail mix for a future hike. The M&M's cost $3 per pound and the peanu

sammy [17]

X - pounds of the M&M`s;
y - pounds of the peanuts
x + y = 30
3 x + 2 y = 74
----------------------
y = 30 - x
3 x + 2 ( 30 - x ) = 74
3 x + 60 - 2 x = 74
x = 74 - 60
x = 14
Answer:
They bought 14 pounds of M&M`s.

Three houses are mapped on a coordinate grid.

Licemer1 [7]

Step-by-step explanation:

Let us consider the task to find the angle between vectors ES and EJ (the first letters are taken to name the vectors).

\overrightarrow{ES} = (4;4) - (4; -3) = \overrightarrow{(0; 7)}

=(4;4)−(4;−3)=

(0;7)

\overrightarrow{EJ} = (-5; -4) - (4; -3) = \overrightarrow{(-9; -1)}

=(−5;−4)−(4;−3)=

(−9;−1)

cos \alpha=\frac{\overrightarrow{ES}*\overrightarrow{EJ}}{|\overrightarrow{EJ}|*|\overrightarrow{ES}|}cosα=

∣∗∣

∣

∗

cos(a) = (0*(-9)+7*(-1)) / (7*9.055) = -0.11043;

a = 96,34°

Solution: 96 degrees.
