olga_2 [115]

Answer:

The space inside the box is the volume, which is 128 ft3

Step-by-step explanation:

Given the dimensions of the box as 8ft by 2ft by 8ft. We calculate it's volume and surface area to validate the statements;

V=lwh\\\\=8\times 2\times 8\\\\=128 \ ft^3\\\\Area=2lw+2lh+2hw\\\\=2(8*2)+2(8*8)+2(2*8)\\\\=192 \ ft^2

The volume of the box is 128 ft^3 and its surface area 192 ft^2. Hence, the correct statement is The space inside the box is the volume, which is 128 ft3

Howard invested $5,000 in Certificate of Deposit (CD) that pays 3.75% interest. compounded weekly. What is the value of the CD a
blsea [12.9K]

Answer:

The value of the CD at the end of the 4 years is $5,808.86.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Howard invested $5,000 in Certificate of Deposit (CD) that pays 3.75% interest.

This means that P = 5000, r = 0.0375

Compounded weekly

An year has 52 weeks, so n = 52

Then

A(t) = P(1 + \frac{r}{n})^{nt}

A(t) = 5000(1 + \frac{0.0375}{52})^{52t}

What is the value of the CD at the end of the 4 years?

This is A(4). So

A(4) = 5000(1 + \frac{0.0375}{52})^{52*4} = 5808.86

The value of the CD at the end of the 4 years is $5,808.86.

Dario bakes a lasagna containing $\frac 23$ pound of parmesan cheese, $1\frac 14$ pounds of ricotta cheese, and $1\frac 13$ poun
svp [43]

Answer: There are 13 slices when Dario cuts .

Explanation :

Since we have given that

Quantity of parmesan cheese is given by

\frac{2}{3}

Quantity of ricotta cheese is given by

1\frac{1}{4}

Quantity of mozzarella cheese is given by

1\frac{1}{3}

Now, total  quantity of cheese Dario have

\frac{2}{3}+\frac{5}{4}+\frac{4}{3}=2+\frac{5}{4}=\frac{8+5}{4}=\frac{13}{4}

Now,

According to question, Dario cuts the lasagna into several equal slices and each containing exactly

\frac{1}{4}\ pounds\ of\ cheese

So,

Number of slices is given by

\frac{\frac{13}{4}}{\frac{1}{4}}=13

Hence, there are 13 slices when Dario cuts .
