First, you should find a common denominator:

Turn 2/5 into 4/10 by multiplying by 2.

Then, find the difference in your fractions:

7/10 - 4/10 = 3/10.

Your answer is 3/10.

2) Jennifer is considering taking out a loan with a principal of

frozen [14]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total value of the loan at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount borrowed

Considering Bank F's offer,

From the information given,

P = $16200

r = 5.7% = 5.7/100 = 0.057

n = 12 because it was compounded 12 times in a year.

t = 8 years

Therefore,

A = 16200(1 + 0.057/12)^12 × 8

A = 16200(1.00475)^96

A = $25531.2

Considering Bank G's offer,

From the information given,

P = $16200

r = 6.2% = 6.2/100 = 0.062

n = 12 because it was compounded 12 times in a year.

t = 7 years

Therefore,

A = 16200(1 + 0.062/12)^12 × 7

A = 16200(1.00517)^84

A = $24980.4

Bank G's offer is better because she would pay a lower amount of interest in total

The amount of arable land in the US in the year 2000 was 20% of total land area. Currently, the amount of arable land in the US

Slav-nsk [51]

The percent change in arable land area in the US over this time period is 12.5%

<h3>Percentage Change</h3>

From the question, we are to determine the percent change in arable land area over the given time

Let the total land area be x

From the given information,

In the year 2000, the amount of arable was 20% of total land area

That is,

Amount of arable land = 20% of x

Amount of arable land = 0.2 × x

Amount of arable land = 0.2x

Currently,

The amount of arable land is 17.5% of total land area

Amount of arable land = 17.5% of x

Amount of arable land = 0.175 × x

Amount of arable land = 0.175x

Thus,

Percent change = (0.2x - 0.175x)/0.2x × 100%

Percent change = 0.025x/0.2x × 100%

Percent change = 0.125 × 100%

Percent change = 12.5%

Hence, the percent change in arable land area in the US over this time period is 12.5%

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The total cost of Haley’s monthly cell

Leokris [45]

The domain of the function C(m) = 0.05m + 20 is (0, ∞) and the range of the function C(m) = 0.05m + 20 is (20, ∞).

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The total cost of Haley’s monthly cell phone bill can be expressed by the function

$\rm C(m) = 0.05\ m + 20$

The domain of the function is from zero to infinity because time can never be negative.

Then the range of the function will be

At m = 0, the value of C(m) will be

C(m) = 0.05(0) + 20

C(m) = 20

At m = ∞, the value of C(m) will be

C(m) = 0.05(∞) + 20

C(m) = ∞

Thus, the domain of the function is (0, ∞) and the range of the function is (20, ∞).
