Area = length × width
45/4 = 9/2 × width
width = (45/4) ÷ (9/2)
= 5/2 feet

A=LW, area equals the product of the length times the width, so we can say:

W=A/L, we are told that A=45/4 and L=9/2 so:

W=(45/4)/(9/2) ft

W=(45/4)*(2/9)=90/36 ft

W=5/2 ft

W=2.5 ft.

2/0 = 32/48 = 30/0. What number shpuld come in place of the zeros?

Anton [14]

Answer:

$\sf \dfrac{2}{3} = \dfrac{32}{48} = \dfrac{30}{45}$

$\sf \rightarrow \dfrac{2}{x} = \dfrac{32}{48}$

$\sf \rightarrow 2(48)= {32x}$

$\sf \rightarrow 32x= 96$

$\sf \rightarrow x = 3$

<u /> $\rightarrow \sf \dfrac{32}{48} = \dfrac{30}{y}$

$\rightarrow \sf {32y} = 30(48)$

$\rightarrow \sf {32y} = 1440$

$\rightarrow \sf y = 45$

Kat is painting the edge of a triangular stage prop with reflective orange paint. The lengths of the edges of the triangle are (

Eva8 [605]

Plug 4 in for every x

(3*4)-4=8
(4^2)-1=15 [(4^2) is 4*4]
(2*(4^2))-15= 15 [because of PEMDAS the exponent comes first and then multiply by 2 then subtract]

Perimeter is the sum of the lengths so add up all the sides from above
8+15+15=38

What is the greatest common factor of 189 and 200 ?

sladkih [1.3K]

The gcf of these two numbers is 1, because 189 and 200 don't have any common factors.
