Hailey wants to hire someone to paint her house. She researched several independent painters who provided information about the

average amount of time it takes them to paint a certain number of square feet of wall space. The three painters with the top ratings are listed in the table below, along with the information they provided.
Name Area Painted
(square feet) Time
(hours:minutes)
Richard 288 45
Gerard 825 2:12
Matthew 992 2:35


Part A: Calculate the unit rate for each painter.

Part B: Compare each pair of painters (Richard with Gerard; Gerard with Matthew; Matthew with Richard), and state whether their rates are in a proportional relationship or not (and why) using their respective unit rates as evidence.

An equation is shown below with a missing value.
bogdanovich [222]

Answer:

The missing value is 512

8=\sqrt[3]{512}

Step-by-step explanation:

Let

x ----> the missing value

we have

8=\sqrt[3]{x}

solve for x

That means-----> isolate the variable x

Elevated both sides to the cube

8^{3}=(\sqrt[3]{x})^{3}

Remember that

(\sqrt[3]{a})^{3}=(a^{\frac{1}{3}})^3=a

so

(\sqrt[3]{x})^{3}=x

substitute

8^{3}=x

512=x

Rewrite

x=512

so

the equation is

8=\sqrt[3]{512}

Using the banker's rule, the minimum annual income needed to borrow $75,000 for the purchase of a home is:
Angelina_Jolie [31]

Answer:

b. $30,000

Step-by-step explanation:

According to the banker rule, the minimum annual income needed to borrowed should be maximum of 2.5% of the annual income

Given that

The amount borrowed for purchased of the home is $75,000

So based on the above information, the minimum annual income is

= Borrowed\ amount \times given\ percentage

= \$75,000 \times 2.5\%

= $30,000

By multiplying the borrowed amount with the given percentage we can get the required minimum annual income and the same is to be shown above

Please help me with this???
Fiesta28 [93]

Answer:

X=3

Step-by-step explanation:

Since all the sides of a square are equal, hence;

5x-2 = x+10

Collect like terms

5x-x = 10+2

4x =12

X = 12/4

X =3

Hence the value of x is 3
