Answer:

28.3 (explaination below)! :)

Step-by-step explanation:

Use the formula for cicrumfrence: C=2πr

Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).

Plug in our numbers. C= 2π4.5

Then, multiply.

You'd get 28.27433388230814.

Rounding to the first decimal place, you'd have a final answer of  28.3.

Hope this helps!

Answer:

11x+5.25

Step-by-step explanation:

Open the brackets

1/2 x 10x= 5x, 1/2 x 6 =3

3/4 x 8x=6x, 3/4 x 3 =2.25

Like terms together

5x + 6x + 3 + 2.25

Answer

11x + 5.25

Answer: 11x+21/4

Step-by-step explanation:

So I shared in the () and then I add them all by making them all having the same denominator and then add them all again , it’s easier to understand with my work .

Question

An expression can often be used to model a real-life situation. For each of the following expressions, write a real-life situation using money as the context. Then, evaluate the expression and interpret the result in terms of the situation. Here's an example.

The following situation is modeled by the expression -24.50 + 100.00: Jonathan overdrew his checking account by $24.50. He then transferred $100.00 from his savings account to his checking account. His new checking account total is $75.50.

Make sure to use complete sentences in your answers.

1) $8.15 + $11.99

2) $20 - $18.04

3) 7($1.45)

4) 42.08 / 4

It's too short. Write at least 20 characters to explain it well.

Step-by-step explanation:

When t = 2,

h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6

Therefore the height after 2 sec is 25.6.

Answer:

[tex]h(t) = 8 + 40.8t - {16t}^{2} \\ h(2) = 8 + 40.8(2) - 16 {(2)}^{2} \\ = 8+81.6 - 64 \\ = 89.6 - 64 = \boxed{25.6}[/tex]

After 2 seconds the ball will be at the height of 25.6 unit.

Answer:  49 square cm

======================================================

For any rectangle, the opposite sides are the same length.

Set the given expressions equal to x and solve to get

2x-1 = x+3

2x-x = 3+1

x = 4

So each opposite side is:

Each side being the same length (7) confirms we have the correct x value.

------------

Let's say L = 7 is the length and W is the unknown width.

We'll use the perimeter of a rectangle formula given below with P = 28 as the given perimeter. Solve for W.

P = 2*(L+W)

28 = 2*(7+W)

28/2 = 7+W

14 = 7+W

7+W = 14

W = 14-7

W = 7

-------------

The rectangle has a length of L = 7 and width of W = 7, so its area is

A = L*W

A = 7*7

A = 49 square cm

Because we have the length and width as the same value, this rectangle is also a square.

Answer:

Step-by-step explanation:

The factored form of (x³ - 1) is option C. (x - 1) (x² + x + 1)

Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.

Given is a cubic polynomial expression.

Given is x³ - 1.

We have to factorize it.

x³ - 1 = x³ - 1³

We have the algebraic expression identity that,

a³ - b³ = (a - b) (a² + ab + b²)

Using the expression, we get,

x³ - 1³ = (x - 1) (x² + x + 1²)

         = (x - 1) (x² + x + 1)

Hence the correct form is option C.

Answer:

C= 2π14.5

C= 91.1061869

91.1061869 X 7.5 = 683.296402

A of a circle = πr squared

as the are two circles to a cylinder 2πr squared

Step-by-step explanation:

Answer: There is 52.8 ounces of the juice in the cup now.

Step-by-step explanation:

We are given that,

The quantity of juice you initially have = 19.3 ounces

You added 33.5 ounces more to the cup.

Then, By using the addition operation, the total quantity of juice in the cup will be (Juice you initially had) + (additional amount)

i.e. The total quantity of juice in the cup= 19.3 + 33.5 ounces

The total quantity of juice in the cup= 52.8 ounces

Hence, there is 52.8 ounces of the juice in the cup now.

divide 5.20 by 6 and you will get 0.87
