If p and q vary inversely and p is 2 when q is 21, determine q when p is equal to 6.

Answers

Answer 1

Answer:

[tex]q = 7[/tex]

Step-by-step explanation:

Given

[tex]p\ \alpha\ \frac{1}{q}[/tex] --- inverse variation

[tex]p =2; q = 21[/tex]

Required

Find q when [tex]p = 6[/tex]

[tex]p\ \alpha\ \frac{1}{q}[/tex]

This becomes

[tex]p = \frac{k}{q}[/tex]

Where k is the constant of variation.

Make k the subject

[tex]k = p * q[/tex]

Substitute [tex]p =2; q = 21[/tex]

[tex]k = 2 * 21[/tex]

[tex]k =42[/tex]

When [tex]p = 6[/tex], we have:

[tex]p = \frac{k}{q}[/tex]

[tex]6 = \frac{42}{q}\\[/tex]

Make q the subject

[tex]q = \frac{42}{6}[/tex]

[tex]q = 7[/tex]

D. $32.90

Answers

The amount of the first payment that will go towards interest is $7.50.

The answer is B. $7.50.

To calculate the amount of the first payment that will go towards interest for an installment loan, we need to consider the principal, term length, and interest rate.

Given:

Principal: $1500.00

Term Length: 4 years

Interest Rate: 6%

Monthly Payment: $35.00

To find the amount of interest paid in the first payment, we'll first calculate the total interest paid over the entire term and then divide it by the number of payments.

Calculate the total interest paid over the term.

Total Interest = Principal × Interest Rate × Term Length

Total Interest = $1500.00 × 6% × 4 = $360.00

Divide the total interest by the number of payments.

Interest in the First Payment = Total Interest / Number of Payments

Interest in the First Payment = $360.00 / (4 years × 12 months per year)

Interest in the First Payment = $360.00 / 48

Interest in the First Payment = $7.50

Therefore, the amount of the first payment that will go towards interest is $7.50.

The answer is B. $7.50.

Answer:

22%

Step-by-step explanation:

First, determine the total: 2392 total surveys.

Next, determine the number of people who prefer Italian: 526

Solve:

526/2392 (This is will determine the percentage of people who prefer Italian food according to the pie chart)

= 0.2198...

Round

= 22%

Answer:

I'm going to say that it is 28% or 22%

Step-by-step explanation:

so they surveyed 2392 people and only 526 of them said that they would eat Italian food so you would do

2392- 526= 1866 then 526/1866=28%

but if that is wrong then you would just do

526/2392=22%

Every five years in March, the population of a certain town is recorded. In
1995, the town had a population of 4500 people. From 1995 to 2000, the
population increased by 15%. From 2000 to 2005, the population
decreased by 4%. What was the town's population in 2005? *
4527
4968
4995
5382

Answers

Answer:

So, the town had a population on 4,500 people in 1995. Then from 1995 to 2000, the population increased by 15%.

Convert 15% to a decimal by dividing it by 100. Then, the population in 1995 by this decimal.

15% ÷ 100 = 0.15

4,500 × 0.15 = 675

Now, add this to the population in 1995.

4,500 + 675 = 5,175

This means that the town had a population of 5,175 people in 2000.

To calculate the town's population in 2005, repeat the same steps we took to find the population in 2000, except this time we will subtract instead of add since the population DECREASED.

4% ÷ 100 = 0.4

5,175 × 0.4 = 207

5,175 - 207 = 4,968

FINAL ANSWER:

The town had a population of 4,968 in 2005.
