Answer:

To find out how much money is in the account after the growth, we can use the formula:

FV = PV(1+r)

Where FV is the future value of the account, PV is the present value of the account, and r is the rate of growth expressed as a decimal.

In this case,

PV = $225

r = 3.2% = 0.032 (as a decimal)

By substituting the values in the formula:

FV = PV(1+r)

FV = $225 * (1 + 0.032)

FV = $225 * 1.032

FV ≈ $232.7 (rounded to two decimal places)

Therefore, the account has $232.7 after the growth of 3.2%.

Answer: $232.20

Step-by-step explanation:

3.2%=0.032

225x0.032=7.2

225+7.2=232.2

Answer:

The surface area of a rectangular prism can be calculated using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Given the dimensions of the rectangular prism as:

Length (l) = 38

Width (w) = 20

Height (h) = 20

Substitute the values in the formula to get:

Surface Area = 2lw + 2lh + 2wh

Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)

Surface Area = 1520 + 1520 + 800

Surface Area = 3840 square units

Therefore, the surface area of the rectangular prism is 3840 square units.

Answer:

3840

Step-by-step explanation:

A=2(wl+hl+hw)=2·(20·38+20·38+20·20)=3840

Answer:

Step-by-step explanation:

The correct answer will be table A.

As we know the property to define X and Y as a function is:

1. All values of X should be unique.

2. All values X should be paired with Y.

3. None of the 2 values of X should be paired with 1 value of Y.

In this case all values of x are unique, and all are valid integers.

The table where y is a function of x is table A.

A function is a relation where each input (x) is mapped into a single output (y).

So, if you see a table where one value of x is related to different values of y, that table does not represent a function.

Knowing that, we can see that the only table where no input is related to more than one variable is table A.

So that is the correct one.

Answer:

I think you just add up all the weights and then you get your answer so just add the numbers I think

Step-by-step explanation:

Answer:

you add all of their weights together.

Step-by-step explanation:

Answer:

To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:

4.8 / 1.2 = 4

5.2 / 1.3 = 4

3.6 / x = 4

Knowing that the scaling for each edge is 4, we can solve for x.

3.6 / 3 = x

1.2=x

So we know the edges for D are 4.8, 5.2, and 3.6 respectively to D’ scaled by 1/4. So we can determine that the edges for D’ are 1.2, 1.3, and 1.2 respectively to D scaled by 4.

So if we go D’ to D, we scale by 4. If we go D to D’, we scale by 1/4.

Answer:

952 cubic feet

Step-by-step explanation:

The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

2385  I think

Step-by-step explanation:

The total number of fiction books in the library are 2385.

The constant of proportionality is the ratio of two proportional values at a constant value.

Let the total number of fiction books be f and nonfiction books be n.

According to the given question.

The constant of propotionality between the number of fiction book(f) and the number of non-fiction books(n) in a library is \(\frac{15}{22}\).

\(\implies \frac{f}{n} = \frac{15}{22}\)

Also, the total number of nonfiction books is 3498.

Therefore,

\(\frac{f}{3498} = \frac{15}{22}\)

\(\implies f = \frac{15}{22} \times 3498\)

\(\implies f = 15\times 159\)

\(\implies f = 2385\)

Hence, the total number of fiction books in the library are 2385.

Answer:  $1487.50

Step-by-step explanation:

hey there again!

Facts:

Principal (starting amount): $1,400

Annual interest rate: 12.5% of the principal. Whenever you get an annual interest rate as a percentage, its always that percentage of the starting amount.

Time given: 6 months, 1/2 a year

the question asks "total amount due' in 6 months. Basically, we want to know how much they will have in their account after 6 months.

Step 1: Find how much interest he will get in 6 months as a percentage.

6 months is 1/2 of a year, so find 1/2 of 12.5

1/2 of 12.5

1/2 x 12.5

0.5 x 12.5

6.25%

Step 2: Find how much interest he gets, but as a number.

Principal: $1400

6.25% of 1400= $87.50

Step 3: Find the total amount of money he will have after 6 months.

he starts with 1400, and gets an additional $87.50 added to his account after 6 months. How much does he have now?

To answer this, add to find the total:

87.50+1400= $1487.50
