Nina delivers newspapers. In the first week, she delivers 8 papers. In the second week, she delivers 32 papers. Which equation can Nina use to find how many times as many papers she delivered the second week as the first week?

Answers

Answer:

a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8x = 32

b) Nina delivered 4 times as many papers the second week as the first week

Step-by-step explanation:

From the question, we are told that:

Nina delivers newspapers.

In the first week, she delivers 8 papers.

In the second week, she delivers 32 papers.

Let x represent the number of times

The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8paper × x = 32 papers

8x = 32

Solving for x

8x = 32

x = 32/8

x = 4 times

Therefore, Nina delivered 4 times as many papers the second week as the first week

Answer:

True

Step-by-step explanation:

Parallel lines always have the same slope, so therefore the answer is True

Answer:

True!

Step-by-step explanation:

These equations are parallel, because all equations that are parallel are going to have the same slope, and both of these equations have the same slope! If it was 5/3 and -3/5, then it would be perpindicular, because that is the negative reciprocal! I hope this helps!

X^2+12=40 what number must you add to complete the square?

Answers

Answer:

Step-by-step explanation:

1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.

2) If you meant X^2+12x=40:

a) Take half of the coefficient of x:  that would be (1/2)(12), or 6.  

b) Square this result, obtaining:  6² = 36

c) Add this 36 to x^2 + 12x + 40, and then subtract it:  We get:  

x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76

We have to add 36, as indicated above, to "complete the square."

Find the percent.
33 is what percent of 40?

Answers

Answer:

33 is 83% of 40.

Step-by-step explanation:

33/40 = 0.825

0.825 equals 82.5%

82.5% rounded is 83%.

I hope this helps!

The required value of percentage is 82.5%. Here, 33 represents approximately 82.5 percent of the total value of 40.

To find the percent, we need to determine what portion of 40 is represented by 33. We can set up a proportion to solve this problem.

Let x represent the unknown percentage.

We can set up the proportion:

33/40 = x/100

To solve for x, we can cross-multiply and then divide:

= (33 × 100) / 40

= 3300/40

Apply division operation to get:

= 82.5

Therefore, 33 is 82.5 percent of 40.

This means that 33 is equivalent to 82.5 percent of 40.
