8.33 Suppose Paul receives a 6% raise every year. After four such raises, what is the total percentage increase to the nearest w
Oksana_A [137]

Answer:

Given:

Suppose Paul receives a 6% raise every year.

To find:

After four such raises, the total percentage increase to the nearest whole percent.

The formula used to calculate percentage is: (value/total value)*100%.

Step-by-step explanation:

Step 1 of 1

Assume his salary is originally  100 dollars.

Then, in the next year, he would have 106 dollars, and in the next, he would have 112.36 dollars.

The next year he would have 119.1016 dollars and in the final year, he would have 126.247.

As the total increase is,

((126.247 -100)/100) *100

= 26.247%

the answer is 26%.

Translate the following verbal expression into an algebraic expression.
poizon [28]

Answer:

3 * (x + 7)

Step-by-step explanation:

Mark number as x

Then the sum of a number and seven is x + 7

Three times x + 7 can be written as

3 * (x + 7)

Parentheses mean that we first add x and 7 and then multiply their sum by 3

Alternatively you can write it as 3x + 21, since

3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

Please help me answer the question in the picture!
Slav-nsk [51]

Answer:

x = 5 units.

Step-by-step explanation:

In a parallelogram. diagonals bisect each other.

This means $ \overline{CE} = \overline{BE} $.

$ \implies 15 - x = 2x $

$ \implies 15 = 3x$

$ \implies x = 5 $.

Therefore, the length of x = 5 units.

Casey orders 3 pizzas and 2 orders of breadsticks for a total of $29.50. Rachel orders 2 pizzas and 3 orders of breadsticks for
saveliy_v [14]

The cost of one pizza is $8.5

Step-by-step explanation:

Let,

Cost of one pizza = x

Cost of one bread stick = y

According to given statement;

3x+2y=29.50    Eqn 1

2x+3y=23          Eqn 2

Multiplying Eqn 1 by 2

2(3x+2y=29.50)\\6x+4y=59\ \ \ Eqn\ 3

Multiplying Eqn 2 by 3

3(2x+3y=23)\\6x+9y=69\ \ \ Eqn\ 4

Subtracting Eqn 3 from Eqn 4

(6x+9y)-(6x+4y)=69-59\\6x+9y-6x-4y=10\\5y=10

Dividing both sides by 5

\frac{5y}{5}=\frac{10}{5}\\y=2

Putting y=2 in Eqn 1

3x+2(2)=29.50\\3x+4=29.50\\3x=29.50-4\\3x=25.5

Dividing both sides by 3

\frac{3x}{3}=\frac{25.5}{3}\\x=8.5

The cost of one pizza is $8.5
