I'm doing a quiz that I didn't finish today can anyone help

3/8 are unfound and  5/8 are found

Step-by-step explanation:

The ratio of unfound to found is 3:5 or a total of 8

3/8 x 40 = 15 unfound

5/8 x 40 = 25 found  

24 nuts do not get found

Step-by-step explanation: x = ?

3 for 5

x for 40

Cross multiply

5x = 3 x 40

5x = 120

Divide both sides by 5

x = 24

24 nuts do not get found.

or

To get 40, you did 5 x 8, so you have to multiply 3 by 8 too.

3 x 8 = 24 :)

Hope that helped!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
