3. Length of a cubic container is 20 cm .A cube with a length of edges 5 cm will be used to take some water from a water barrel. Determine the maximum number of cubes that need to use to fill the container with water.​

Answers

Answer 1
Answer:

We have l = 20 * 20 * 20 = 8000 cm3

One cube will have l = 5 * 5 * 5 = 125 cm3

-> The maximum number of cubes that need to use to fill the container with water is 8000 / 125 = 64

Answers

Answer:

D.) It has a common difference of 3.8

Step-by-step explanation:

When you subtract a_(2) -a_(1) you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8

Tamora has just graduated from college. When she entered college four years ago, she took out a $9,100 subsidized Stafford loan, which has a duration of ten years. The loan has an interest rate of 5.4%, compounded monthly. If Tamora makes monthly payments, how much interest will she have paid in total by the time the loan is paid off? Round all dollar values to the nearest cent.

Answers

After ten years, Tamora will have spent $6.496.76 on interest.

What is Compound interest?

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

Given, Tamora has just graduated from college. When she entered college four years ago, she took out a $9,100 subsidized Stafford loan, which has a duration of ten years. The loan has an interest rate of 5.4%, compounded monthly.

The total amount of interest to be paid can be expressed as;

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

where;

A = Total amount of interest

P = principal amount of the loan

r = annual interest rate

n = number of compounding periods in a year

t=number of years

In our case;

P=$9,100

r=5.4%=5.4/100=0.054

n=12

t=10 years

Replace the values and solve

A=9,100{(1+0.054/12)^(12×10)}-9,100

A=9,100{(1.0045)^120}-9,100

A=6,496.7575

The sum has been rounded to the closest penny. The equivalent of rounding to the nearest decimalplace is 1/100=0.01.

A=$6,496.76

Tamora will have paid $6.496.76 in interest overall after ten years.

Answer:

The total interest amount that Tamora will have paid in 10 years=$6.496.76

Step-by-step explanation:

Step 1: Express the formula for calculating total amount of interest

The total amount of interest to be paid can be expressed as;

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

where;

A=total amount of interest

P=principal amount of loan

r=annual interest rate

n=number of compounding periods in a year

t=number of years

In our case;

P=$9,100

r=5.4%=5.4/100=0.054

n=12

t=10 years

Step 2: Replace the values and solve

A=9,100{(1+0.054/12)^(12×10)}-9,100

A=9,100{(1.0045)^120}-9,100

A=6,496.757596

The amount rounded off to nearest cent 1/100=0.01 is the same as rounding off to nearest  decimal places

A=$6.496.76

The total interest amount that Tamora will have paid in 10 years=$6.496.76

A store sells new video games for $45 each. Used video games sell for $18 each. Alex is buying 2 new video games and x used video games. Which equation can be used to find y, the total price Alex must pay in dollars?

Answers

Answer:

u = t/18 - 5

Step-by-step explanation:

45n + 18u = t where t is the total price, n is the number of new video games, and u is the number of used video games

plug in two:

90 + 18u = t

solve in terms of u:

18u = t - 90

u = t/18 - 5
