Let, the numbers are: 8x, 5x
It is given that, 8x - 5x = 24
3x = 24
x = 24/3
x = 8

So, 8x = 8(8) = 64 
also, 5x = 5(8) = 40

In short, Numbers would be 40 and 64

Hope this helps!

If a 42.9 ft tall flagpole casts a 253.1 ft long shadow then how long is the shadow that a 6.2 ft tall woman casts?
blsea [12.9K]
We will have to use proportions:
\frac{42.9}{253.1}  =  \frac{6.2}{x}
Cross multiplying we get
42.9x = 6.2 \times 253.1
Now divide:
x =  \frac{6.2 \times 253.1}{42.9}
Solve to tenths place we get
x = 36.6
The woman casts a 36.6 ft long shadow.

A rectangle is 32m by 8m is similar to a rectangle 4m by x m. Find the 2 possible values of x .
Stella [2.4K]
<h3>Answers:</h3><h3>x = 1 or x = 16</h3>

======================================

Work Shown:

Draw out a rectangle that is 32 units wide horizontally and 8 units tall vertically.

Then draw out another rectangle that is 4 meters wide horizontally and x meters tall vertically.

The horizontal and vertical sides pair up to form these fractions: 32/4 and 8/x

Set the fractions equal to one another. Solve for x

32/4 = 8/x

32x = 8*4 ... cross multiply

32x = 32  

x = 32/32 ... divide both sides by 32

x = 1

-----------------------

Somewhere else on your paper, draw the same 32 by 8 rectangle to make 32 the horizontal component

Next to this rectangle, draw a rectangle that has x as the horizontal part and 4 as the vertical. Note the swap here.

We now have this equation to solve for

32/x = 8/4

once again, note the swap

Let's solve for x

32/x = 8/4

32*4 = 8*x

128 = 8x

8x = 128

x = 128/8

x = 16

What is the total surface area of the figure?
WITCHER [35]

Answer:

531 in²

Step-by-step explanation:

5 faces of the cube are facing the surface because the top one is shared with the triangular prism.

Surface area of a cube is S = 5 × (9)²

S = 405 in²

Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).

S = (1/2)7×(4×9)

S = 126 in²

Add 126 + 405 to get 531 in²
