7th Grade Math:

A library keeps track of the number of overdue items at the end of each month.

* At the end of April, there were x overdue items.

* At the end of May, the number of overdue items was 3% less than the number of overdue items at the end of April.

The expression x - 0.03x represents the number of overdue items at the end of May. Which sentence best explains how to simplify the expression that represents the number of overdue items at the end of May?

A. Combine x and 0.03x, since they are like terms, by cancelling out the x.

B. Combine c and 0.03x, since they are like terms, by subtracting 1 - 0.03 to find the new coefficient.

C. Factor out an x, since it appears in both terms, leaving 1 in the first term and 0.03x in the second term.

D. Factor out an x, since it appears in both terms, eliminating the first term and leaving 0.03 in the second term.

Answers

Answer 1

Answer:

(Mostly) C. Or D

Step-by-step explanation:

Because you first have to factor out the equation by factoring the x . The this will leave you with the terms. Hopefully This Helps.

What is the radius of a sphere with a volume of 320 ft 3 , to the nearest tenth of a foot?

Answers

Answer:

A=10240033.0/pift /ft

Step-by-step explanation:

Calculate the area of circle:

Round the number: A=10240033.0/pift /ft

Answer: A=10240033.0/pift /ft

The radius of the sphere is 4.2 feet.

What is a Sphere?

A sphere is a geometrical shape in three dimension which has every point on the surface of it at an equal distance from a common point called the center of the sphere.

Volume of a sphere is given by the equation,

Volume = [tex]\frac{4}{3}[/tex]πr³, where r is the radius.

We have volume of the given sphere = 320 feet³

Substituting this value in the main equation, we get,

320 =  [tex]\frac{4}{3}[/tex]πr³

320 × 3 = 4πr³

960 / 4π = r³

960 / (4 × 3.14) = r³

r³ = 76.43

r = 4.24 ≈ 4.2

Hence, the radius of the sphere with a volume of 320 feet³ has a radius of 4.2 feet, to the nearest tenth of a foot.

Forty pounds of candy is distributed in 5/7 lb bags. How many bags can be filled?
_______ bags can be filled.

Answers

Answer:56 bags

Step-by-step explanation:

you are dividing 40 into 5/7 so its technically 40*7 divided by 5, which equals 56. double check by doing 56*5 divided by 7 and you get 40 pounds,

[tex]\frac{40(7)}{5}[/tex]Answer:

To find out how many can be filled, divide the number of pounds of candy by the number of pounds a single bag can hold.

40 can be considered 40/1.

So,

40/1 ÷ 5/7

Make 5/7 a reciprocal(basically flipping the fraction upside down):

40/1 ÷ 7/5

Convert the division symbol into a multiplication symbol:

40/1 × 7/5

Solve!

[tex]\frac{40(7)}{5}[/tex]

Cancel:

[tex]\frac{8(7)}{1}[/tex]

= 56 bags can be filled.

At a Harare swimming club, there are 35 girls and 25 boys. . In a Bulawayo swimming club, there are 22 girls and 14 boys. Which swimming club has the greatest proportion of girls? Explain how you worked out your answer. ​

Answers

Answer:

  Bulawayo

Step-by-step explanation:

Proportions can be compared numerous ways. Here, we find it convenient to look at the difference between girls and boys relative to the number of boys.

__

Harare

With 35 girls and 25 boys, there are 10 more girls than boys. 10 is less than half of the number of boys, so the ratio of girls to boys is less than 1.5.

Bulawayo

With 35 girls and 15 boys, there are 8 more girls than boys. 8 is more than half of the number of boys, so the ratio of girls to boys is more than 1.5.

Comparision

"More than 1.5" is greater than "less than 1.5", so Bulawayo has the greatest proportion of girls.
_____

Additional comment

As a fraction of the total, the proportions of girls are ...

  Harare: 35/(35+25) = 35/60 = 7/12 = 21/36

  Bulawayo: 22/(22+14) = 22/36 . . . . . . greater than 21/36.

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

Answers

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

[tex]1\frac{2}{3}[/tex] × 3

[tex]1\frac{2}{3}[/tex] can be rewritten as [tex]\frac{5}{3}[/tex], so:

[tex]\frac{5}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]= \frac{15}{3}[/tex]

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the y-axis and time on the x-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

Answer:

B. Every 5 minutes 11 ft. traveled

2.2ft.= every 1 minute

C. Steeper. this is because her rate of change is much higher than before
