Aaron buys erasers for his pencils. Each eraser costs $0.20. The total cost is $1.20. How many erasers does Aaron buy? Solve this problem any way you choose.

Answer:

Option A

Step-by-step explanation:

[tex]R = (\frac{V_f-Vi}{V_i} )100[/tex]

where,

[tex]V_f[/tex] is the final value

[tex]V_i[/tex] if the initial value

R is the investors rate of return

so,

[tex]R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\[/tex]

so the investors rate of return is -11.8%

Step-by-step explanation:

Here, we want to give the team’s best time for the race

from the question, we should understand that the best times are the smallest in values since it is a race

The smallest time here is 56.81 seconds and thus that is the team’s best time for the race

Step-by-step explanation:

Step 1: Define Expression

12(x - 2 - 3x) + 14

Step 2: Simplify

Answer:

-10/24

Step-by-step explanation:

12(x-2-3x)+14=0

12(-2-2x)+14=0

-24-24x+14

-10-24x=0

24x=-10

x=-10/24

x/x^2-9 + 1/x-3 = 1/4x-12

x/(x+3)(x-3)+1/(x-3)=1/4(x-3)

LCD: 4(x+3)(x-3)

4x+4(x+3)=(x+3)

4x+4x+12=x+3

7x=-9

x=-9/7

Given:

The ratio is

[tex]\dfrac{1}{4}:\dfrac{1}{3}[/tex]

To find:

The given ratio as unit rate.

Solution:

We have,

[tex]\dfrac{1}{4}:\dfrac{1}{3}[/tex]

Fraction form of given ratio is

[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{3}}[/tex]

[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{1}{4}\times \dfrac{3}{1}[/tex]

[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{3}{4}[/tex]

[tex]\dfrac{1}{4}:\dfrac{1}{3}=0.75[/tex]

Therefore, the unit rate of the given ratio is 0.75.

Answer:

The dimensions of the garden is 102 feet by 68 feet

Step-by-step explanation:

Here, we want to get the width and length of the garden

The perimeter is represented by the length of the fencing

From the question;

w = 2l/3

The formula for the perimeter is;

P = 2(l + w)

Thus;

340 = 2(l + 2l/3)

170 = (l + 2l/3)

Multiply through by 3

510 = 3l + 2l

5l = 510

l = 102 feet

w = 2/3 * l

w = 2/3 * 102

w = 68 feet

Answer:

12.5 ft

Step-by-step explanation:

5/2 = 2.5

5*2.5 = 12.5 ft

Step-by-step explanation:

Answer:

The answer would be no, Monica is wrong.

Step-by-step explanation:

By using the formula for simple interest; Time ( $ x Rate) = Interest

After a year, Monica would have gotten $40.80 in interest,

Paul would have gotten $81.60 in interest.

Because Paul deposited a higher amount of money than Monica, Paul earns more interest.

Answer:

2500 children and 2500 adults

The number of children is 2500 and the number of adults that attended the game is also 2500.

Let us consider that, number of children be x and number of adults be y that attend game.

Since, total 5000 people attend the game.

               [tex]x+y=5000\\\\x=5000-y..........(1)[/tex]

It costs $3 for children and $7 for adults and the total takings at the door was $25000

              [tex]3x+7y=25000 .............(2)[/tex]

Substitute value of x from equation 1 into equation 2.

           [tex]3(5000-y)+7y=25000\\\\15000-3y+7y=25000\\\\4y=10000\\\\y=10000/4=2500[/tex]

So that, [tex]x=5000-2500=2500[/tex]

Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.

Answer:

C. x-2

Step-by-step explanation:

x² + 7x - 18 = 0

the factor must be p and q from the form.of

(x+p)(x+q) = 0

then find the value of p and q by this rules

p + q = 7

p x q = -18

p = 9

q = -2

(x + 9)(x + (-2)) = 0

(x+9)(x-2) = 0

Answer:

c.) [tex](x-2)[/tex]

Step-by-step explanation:

The given expression is written in the form [tex]ac^2+bx+c[/tex]. To factor, find two numbers whose sum is b and whose product is c:

_×_=-18

_+_=7

Use -2 and 7:

-2×9=-18

-2+9=7

Substitute the two numbers for b:

[tex]x^2-2x+9x-18[/tex]

[tex](x^2-2x)+(9x-18)[/tex]

Factor out common terms. The common term in the first parentheses is x and the common term in the second is 9:

[tex]x(\frac{x^2-2x}{x} )+9(\frac{9x-18}{9})\\\\x(x-2)+9(x-2)[/tex]

Cancel out one of the parentheses since they have the same terms and plug the factored numbers in:

[tex](x-2)(x+9)[/tex]

:Done

Check Your Work:

To see if the given factored form is true, simplify it using FOIL:

First, Outside, Inside, Last

[tex](x-2)(x+9)[/tex]

Multiply the first terms:

[tex]x*x=x^2[/tex]

Multiply the terms on the outside:

[tex]x*9=9x\\\\x^2+9x[/tex]

Multiply the inside terms:

[tex]-2*x=-2x\\\\x^2+9x-2x[/tex]

Multiply the last terms:

[tex]-2*9=-18\\\\x^2+9x-2x-18[/tex]

Combine like terms:

[tex]x^2+(9x-2x)-18\\\\x^2+7x-18[/tex]

Therefore, the factored form is true.

Answer: -273

Step-by-step explanation:

This is an arithmetic progression and the formula to find the nth term is given as:

= a + (n-1)d

Therefore, the 100th term will be:

= a + (n-1)d

= a + (100 - 1)d

= a + 99d

where a = 222

d = -5

Therefore, a + 99d = 222 + 99(-5)

= 222 + (-495)

= 222 - 495

= -273

Answer: 149.12

Step-by-step explanation:

to find out the extended warranty we do,

466*(32/100)=149.12

The extended warranty cost is $149.12.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a set of floor speakers costs $466.

If the extended warranty on the speakers costs 32% of the price of the speakers.

Now, extended price =32% of 466

32/100 ×466

= 0.32×466

= $149.12

Therefore, the extended warranty cost is $149.12.
