Answer:

The first increase was of 60%.

Step-by-step explanation:

The initial value of the product is x.

The first increase was of y.

The second increase is of 25%, that is, 1.25.

The final price was double the original, so 2x.

This situation can be modeled by the following equation:

[tex]xy(1.25) = 2x[/tex]

We want to find y.

Simplifying by x

[tex]1.25y = 2[/tex]

[tex]y = \frac{2}{1.25}[/tex]

[tex]y = 1.6[/tex]

After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

Answer:

[tex]3x^3-3y-3[/tex]

Step-by-step explanation:

Answer:

here,

15 pound bag =$6.30

or, 1 pound bag = 6.30/15

or, 1 pound bag = $0.42

or,29 pound bag = 29 X $ 0.42

or, 29 pound bag = $ 12.18

Hence, a 29 pound bag of apple cost $12.18

Answer:

B. 112°

Step-by-step explanation:

4x -4 = (3x+4) + (2x-44)

4x -4 = 5x - 40

5x - 4x = -4 + 40

x = 36

∠BCA = 3 * 36 + 4 = 112

Answer:

Cups of chopped celery in original recipe = [tex]\frac{3}{4}\ cups[/tex]

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

[tex]\frac{2}{3}c=\frac{1}{2}[/tex]

Multiplying both sides by 3/2

[tex]\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\[/tex]

Hence,

Cups of chopped celery in original recipe = [tex]\frac{3}{4}\ cups[/tex]

Answer:

if we take the total cost of the grapes, and divide by the number of pounds of grapes we can conclude that each pound of grapes costs $3. so 5 pounds of grapes multiplied by $3 per pound, gives us $15 for 5 pounds of grapes.

Answer:

$15

Step-by-step explanation:

If 2 pounds of grapes cost $6, then one pound of grapes would be $3, because 6 divided by 2 (because there is two pounds) would equal 3. 5 pounds of grapes would cost $15 because 3+3+3+3+3 (or 5 x 3) is equal to 15.

Answer:

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]

Step-by-step explanation:

Explanation:-

Given A high school club has 10 members who are seniors and 8 members who  are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will  be a senior

The probability that the person will  be a senior

      [tex]P(E) = \frac{n(E)}{n(S)}[/tex]

     [tex]P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}[/tex]

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]

Step-by-step explanation:

General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = ax + b.

=> y - b = ax

=> y - b = a(x - 0).

The answer is option A.

Answer:

A

[tex]general \: equation \: of \: line \\ y = mx + c \\ from \: the \: data \: given \\ m = a \\ c = b \\ y = ax + b \\ y - b = ax \\ y - b = a(x - 0)[/tex]
