Answer:

68 ft^2

Step-by-step explanation:

Find the area of the large rectangle as if the piece were there

A = l*w

A = 6 * 14

A =84

Subtract the area of the square that is missing

A = 4*4 = 16

84 - 16 =68

Answer:

X=4

Step-by-step explanation:

Let's make an equation,

7/4 ÷ 14 = x ÷ 3

We can cross multiply

7/4 * 32 = x * 14

Now we have 56 = 14x

Divide both sides by 14

56 ÷ 14 = 4, 14x ÷ 14 = x

4 = x

x = 4

Answer:

  $87.50

Step-by-step explanation:

To answer this question, you make use of the formula for simple interest:

  I = Prt

This is the interest I on principal amount P at annual rate r for t years.

You have P = $3500, r = 0.025, t = 1, so the interest is ...

  I = $3500×0.025×1 = $87.50

You would receive $87.50 in interest on your savings account.

Additional comment

Many calculators, and all spreadsheets, can use a percentage number directly in the calculation. If yours can't, then you must convert the percentage to a decimal fraction. You can think of the "%" symbol as equivalent to "/100" or "×0.01". The decimal equivalent of 2.5% is 2.5/100 or 2.5×0.01 = 0.025.

__

We have assumed the account earns simple interest, because there is no mention of interest compounding, or of a monthly accounting. In many real-life savings accounts, the interest is computed each month and added to the balance. The computation for the following month includes interest on the interest earned previously. We say the interest is compounded in that case. The formula for compound interest is different from the one shown here.

Answer:

1. Hence, the answer is $74.50

2. Hence, the answer is 16.

Step-by-step explanation:

1. Given: Natalie and her friends decide to rent 4 lanes at regular cost for a party. Ten people need to rent shoes, adn 4 people are members.

To find: What is the total cost for the party?

Solution:

Since Natalie and her friends wanted to rent four lanes, we need to calculate this at REGULAR cost.

4 * 9 .75 = 39

Now since 10 people want to rent shoes, and 4 people are members, we subtract.

10 - 4 = 6

6 nonmembers

4 members

6 times the amount of shoe rental for 6 * 3.95 - 23.70

non members

4 times the number of members shoe rental 4* 2.95

11. 80

Now add the quantities

39 + 11.80 + 23.70 += 50.80 + 23.70 =

74.50

Now, our answer is 74.50

2.

Solution:

20 / 1.25 = 16

So the possible amount that can be bought is 16 medium sodas.

A) The monthly percentage rate of Felix is;

B) The monthly percentage rate of Oscar is;

C) The amount that Oscar will pay more than Felix is; $0.96

A) Felix was given a card with APR of 14%.

Thus;

Monthly percentage rate = 14%/12 = 1.63%

B) Oscar was given a card with an APR of 21%. Thus;

Monthly percentage rate = 21%/12 = 1.75%

C) We are told that each of them had an average daily balance of $800 for a specific month.

Thus;

Amount paid by Felix = 800 * 1.63%

Amount paid by Felix  = $13.04

Amount paid by Oscar = 800 * 1.75%

Amount paid by Oscar = $14

Difference in Payments = $14 - $13.04 = $0.96

Thus, Oscar pays $0.96 more than Felix.

a. felix: 14/12 = 1.167% (round to nearest hundredth = 1.17%)

b. oscar 21/12 = 1.75% (no need to round here)

c.

felix: (1.17/100) x 800 = 9.36

oscar: (1.75/100) x 800 = 14.00

14.00 - 9.36 = 4.64

oscar will pay $4.64 more than felix.

The location of the tree can be found by taking point A as the origin of

coordinate plane, represented by the drawing area.

Response:

The area Tom wants to plant the tree in the garden is given by the following rule;

Distance of the tree from A = 4 m

Distance of the tree from CD = 2 m

1 cm in the scale drawing = 2 m

Solution:

Taking point A as the origin, we have;

The location of the tree from point A is given by the radial length, r = 2 cm.

The distance of the tree from the line CD is given by the line, y = 1.5 cm,

given that 1 cm from CD = 1.5 cm from point A

Therefore, we have;

Where;

r = 2

y = 1.5

We have;

x² + 1.5² = 2²

x² = 2² - 1.5² = 1.75

Step-by-step explanation:

1 cup of yellow paint = 2×1/2 cup.

and that requires then also 2×1/3 Co red paint.

so, 1 cup of yellow paint mixes with 2/3 cups of red paint.

2 and 3 have a smallest common multiple (smallest number that is divisible by both numbers without remainder) of 6.

so, we need to get 6 units of each for a whole number ratio :

6×1/2 = 3 cups of yellow paint mix with 6×1/3 = 2 cups of red paint.

Answer:

Step-by-step explanation:

Answer:

Slope = -¾

Step-by-step explanation:

Given the points, (-20,-4) and (-12, -10), use the following formula to solve for the slope:

m = (y₂ - y₁)/(x₂ - x₁)

Let (x₁, y₁) = (-20,-4)

     (x₂, y₂) =  (-12, -10)

Substitute these values into the slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

[tex]m = \frac{-10 - (-4)}{-12 - (-20)}[/tex]

[tex]m = \frac{-10 + 4}{-12 + 20}[/tex]

[tex]m = \frac{-6}{8}[/tex]

Simplify the fraction into its lowest terms by dividing the numerator and the denominator by 2:

[tex]m = \frac{-6}{8}[/tex] ÷  [tex]\frac{2}{2}[/tex]

m = -¾

Therefore, the slope of the line is -¾

Answer:

3xy² -  14y²      

Step-by-step explanation:

I hope that this is the problem

   - x²y + [ - (x²y - 2xy² + y²) + (xy² - 3y² + x²y)] - (10y² - x²y)

= - x²y + [ - x²y + 2xy² - y² + xy² - 3y² + x²y] - 10y² + x²y

Now combine like terms in the [  ].

= - x²y  + [ -x²y + x²y + 2xy² + xy² - y² - 3y² ] - 10y² + x²y

= - x²y  + [ 0 + 3xy² - 4y²] - 10y² + x²y

= - x²y + 3xy² - 4y² -10y² + x²y                      Now combine like terms

=   (-x²y + x²y) + 3xy² + (-4y² - 10y²)

=       0 + 3xy² - 14y²

=  3xy² -  14y²       or    y²(3x - 14)
