Arisa [49]2 years ago
5 0

Answer:

n = 3 Year (Approx)

Step-by-step explanation:

Given:

Growth rate (r) = 45% = 0.45

Find:

Number of year for 3 times of population (n)

Computation:

Assume;

Current population = P

So,

New population = 3P

A = p(1+r)ⁿ

3P = P(1+0.45)ⁿ

3 = (1.45)ⁿ

n = 2.96 year

n = 3 Year (Approx)

What is the area of the label on a soup can that is 8 inches high and has a diameter of 4 inches? Round to the nearest hundredth
olga_2 [115]

Answer:

Area of label = 100 inch² (Approx.)

Step-by-step explanation:

Given:

Height of label = 8 inches

Diameter of label = 4 inches

Find:

Area of label

Computation:

Design of label = Rectangle

So,

Width of label = 2πr

Width of label = 2(3.14)(4/2)

Width of label = 2(3.14)(2)

Width of label = 12.56 inches

Area of label = Height of label x Width of label

Area of label = 12.56 x 8

Area of label = 100.48

Area of label = 100 inch² (Approx.)

U=1-3v/vt-w make t the subject
Jobisdone [24]
u = 1 - \dfrac{3v}{vt-w}

\dfrac{3v}{vt-w} = 1 - u

3v = (1 - u)(vt - w)

3v = vt - w - uvt + wu

vt - uvt = 3v + w - wu

t(v - uv) = 3v + w - wu

t =  \dfrac{3v + w - wu}{v - uv}

scoundrel [369]

Answer:

12 hr. mowing lawns

28 hr. working at Mc Donalds

Step-by-step explanation:

Let t = time mowing lawns

then 40 - t = time working at McDonalds

7,5(40 - t) + 6t = 282

300 - 7.5t + 6t = 282

-1.5t = -18

t = 12 hr. mowing lawns

40 - t = 40 - 12 = 28 hr. working at Mc Donalds
