Hello There!

Ethan would pay $31.99 or rounded up two 32 which ever is your answer choice

Thus being why.

if you times 39.99 x .20 you get 7.998

39.99 - 7.998 is 31.99

Hope This Helps!

In this diagram, BAC~EDF. If the area of BAC=15 in2, what is the area of EDF? 4, 5.

lesya692 [45]

Answer:

9.6 square inches.

Step-by-step explanation:

We are given that ΔBAC is similar to ΔEDF, and that the area of ΔBAC is 15 inches. And we want to determine the area of ΔDEF.

First, find the scale factor k from ΔBAC to ΔDEF:

$\displaystyle 5 k = 4$

Solve for the scale factor k:

$\displaystyle k = \frac{4}{5}$

Recall that to scale areas, we square the scale factor.

In other words, since the scale factor for sides from ΔBAC to ΔDEF is 4/5, the scale factor for its area will be (4/5)² or 16/25.

Hence, the area of ΔEDF is:

$\displaystyle \Delta EDF = \frac{16}{25}\left(15\right) = 9.6\text{ in}^2$

In conclusion, the area of ΔEDF is 9.6 square inches.

Each cube in this solid figure is a unit cube. What is the volume of this solid figure?

padilas [110]

Answer:

The volume of this given solid figure is 18 cubic units.

Step-by-step explanation:

Here, given the volume of 1 small cube = 1 cubic units

Now, counting the total cubes in the given solid figure, we get

Number of cubes in base row = 10

Number of cubes in middle row = 6

Number of cubes in top most row = 2

So, the total number of cubes in the figure = 10 + 6 + 2 = 18 cubes

So, the volume of 18 cubes = 18 ( Volume of 1 small cube)

= 18 x (1 cubic units) = 18 cubic units

Hence, the volume of this given solid figure is 18 cubic units.
