Joey completed 1,456 push-ups over a 4-week period. Joey did the same number of push-ups every day. How many push-ups did Joey do each day?

Answers

Answer:

Joey completed 52 pushups each day.

Step-by-step explanation:

We know that he did 1,456 pushups in 4 weeks, and that there are 7 days a week. This means that he did those pushups in the span of 28 days. So, divide 1,456 by 28 to get 52 pushups.

Noah said, “When you divide a number by a second number, the result will always be smaller than the first number.”

Jada said, “I think the result could be larger or smaller, depending on the numbers.”

Do you agree with Noah or Jada? Show or explain your reasoning.

Answers

Answer:

When dividing two fractions by each other, the result will be larger. Dividing two whole numbers, however, will always result in a smaller number because you're taking away a part of the number.

3200 dollars is placed in an account with an annual interest rate of 8.25%. To the
nearest tenth of a year, how long will it take for the account value to reach 9600
dollars?

Hello, I come from the deltamath past to help you, in the deltamath future. It’s 13.9

Answers

It takes 24 years for the account value to reach the $9600.
Step-by-step explanation:
From the given data, it can be determined that :
Amount = $9600
Principal = $3200
Rate = 8.25% = 0.0825
Number of years should be calculated.
To find the interest :
Amount = Principal + Interest
Therefore, the interest can be calculated by the formula,
Interest = Amount - Principal
⇒ 9600 - 3200
⇒ 6400
The interest needed is 6400.
To find the number of years required to reach this interest :
Use the formula for simple interest,
Simple interest = Pnr /100
where,
P is the principal
n is the number of years
r is the rate
Substitute all the given values in the simple interest formula,
Simple interest = 3200 × n × 0.0825
6400 = 264 n
n = 6400 / 264
n = 24.2 which is approximately 24 years.
Therefore, it takes 24 years for the account value of 3200 dollars to reach 9600 dollars.

machine A covers 5/8 square feet in 1/4 hour or machine B covers 2/3 square feet in 1/5 hour

Answers

Answer:

The unit rate would be square footage covered in 1 hour. Since 5/8 square foot is the area covered in 1/4 hour, you would multiply by 4 to determine the amount of area covered in 1 hour:

5 x 4 = 20

8 1 8

20 is equivalent 2 and 1 square feet in 1 hour

8 2

Answer:

The number of yards in 5 miles will be: 8800 miles

Step-by-step explanation:

The double numbers line shows the ratio of yards to miles.

From the number line, it is clear that

at 2 miles, the number of yards is 3520.

Thus,

The unit rate = 3520 yards / 2 miles

= 1760 yards / per mile

Thus, the number of yards in 5 miles will be:

1760 × 5 = 8800 miles

Therefore, the number of yards in 5 miles will be: 8800 miles

( x + 5 ) · ( x + 1 )

Step-by-step explanation:

-Factoring by grouping-

First, split the middle term into two parts that are factorable by the other variables.

x² + x + 5x + 5

Factor the parts

x · ( x + 1 ) + 5 · ( x + 1 )

( x + 5 ) · ( x + 1 )

Answer:

Step-by-step explanation:

Given

x² + 6x + 5

Consider the factors of the constant term (+ 5) which sum to give the coefficient of the x- term (+ 6)

The factors are + 1 and + 5 , since

1 × 5 = + 5 and 1 + 5 = + 6, thus

x² +6x + 5 = (x + 1)(x + 5) → C
