If 40% of a number is 32, what is 25% of that number?

What you need to do is divide 32 by 40 so you end up with 1%. Then you need to multiply that by 25 and you will get 25%

32÷40=0.8

0.8x25=20

Let the number be x.

40% of x = 32

(40/100)*x = 32

x = 32 * (100/40)

x = 32 * 2.5

x = 80

The number is 80.

Finding 25% of the number

25% of 80

(25/100) * 80

(1/4)* 80

20

25% of that number is = 20.

I hope that this helps.

The amount of polonium-210 remaining, p(t), after t days in a sample can be modeled by the exponential function p(t) = 100e−0.00
Archy [21]

Answer:

% Po lost = 100[1 - e^(-0.005t)]  %; 73.0 g

Step-by-step explanation:

p(t) = 100e^(-0.005t)

Initial amount:        p(0) = 100

Amount remaining: p(t) = 100e^(-0.005t)

Amount lost: p(0) – p(t) = 100 - 100e^(-0.005t) = 100[1 - e^(-0.005t)]

% of Po lost  = amount lost/initial amount × 100 %

= [1 - e^(-0.005t)]  × 100 % = 100[1 - e^(-0.005t)]  %

p(63) = 100e^(-0.005 × 63) = 100e^(-0.315) = 100 × 0.730 = 73 g

The mass of polonium remaining after 63 days is 73 g.

A window shaped like a parallelogram has an area of 30 square feet. The height of the window is 4
Viefleur [7K]

Answer:

The base of the window is 7.5 feet long.

Step-by-step explanation:

The area of a parallelogram can be found with the formula A = bh

Plug in the known values to get 30 = 4b

30 = 4b

30/4 = b

7.5 = b
