Answer:

the length of FC = b = 12 cm

Step-by-step explanation:

The volume of prism is given along with height and height of triangular base. WE need to find the length of base.

V= B*h

where B= area of base = 1/2 * b *h

V= ( 1/2 *b * h) * h

900= 1/2 * b * 10 * 15

900 * 2 = b* 150

1800 = b* 150

=> b= 1800/150

b= 12 cm

So the length of FC = b = 12 cm

Suppose that 1 kg of Sodium-24 is reduced to 0.0156 kg in 90 hours. What is the half-life, in hours, of Sodium-24?​
N76 [4]

Answer:

14.99 hours

Step-by-step explanation:

The formula for half-life is given as,

R/R' = 2ᵃ/ᵇ...................... Equation 1

Where R= Original mass of sodium-24, R' = mass of Sodium-24 after disintegration, a = Total time taken for sodium-24 to disintegrate, b = half-life of sodiun-24.

Given: R = 1 kg, R' = 0.0156 kg, a = 90 hours

Substitute into equation 1 and solve for b

1/(0.0156) = 2⁹⁰/ᵇ

Taking the log of both side

log[1/(0.0156)] = log(2⁹⁰/ᵇ)

log[1/(0.0156)] = 90/b(log2)

90/b = log[1/(0.0156)]/log2

90/b = 6.0023

b = 90/6.0023

b =  14.99 hours

b = 14.99 hours.

Hence the half-life of Sodium-24 is 14.99 hours

adelina 88 [10]

C. $34.50. A car gets 30 miles per gallon, if the gasoline cost $1.15 per gallon, a 900 miles trip will cost $34.50

This exercise can be solved by simply arithmetic.

Divide the total miles by the miles per gallon:

900/30 = 30

Then, multiply this value by the cost per gallon:

30 x $1.15 = $34.50
