John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit. Caleb decided to go to Club4Fitness, which just charges $8 per visit. After how many visits have John and Caleb spent the same amount of money, and how much money did they spend?
Answers
Answer:
10 visits
Step-by-step explanation:
John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.
Let the number of visits be represented as: x
For John
John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.
The equation = $30 + $5 × x
= 30 + 5x
For Caleb
Caleb decided to go to Club4Fitness, which just charges $8 per visit.
The Equation = $8 × x
= 8x
We equate both equations to each other
30 + 5x = 8x
Collect like terms
30 = 8x - 5x
30 = 3x
x = 30/3
x = 10
Therefore, John and Caleb would spent the same amount of money after 10 visits.

A picture that measures 10 cm long is reduced on a copy machine to 4 cm long. If the width of the original picture is 6 cm, what is the width
of the reduced picture? Set up a proportion to solve this problem?
Answers
2.4 cm
Step-by-step explanation:
10/4 = 6/x
x = width of reduced picture
24 = 10x (cross multiplication)
24/10 = x
2.4 = x
The width of the reduced picture is 2.4 cm.
Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?
q + d = 6 25q + 10d = 33
q + d = 6 0.25q + 0.1d = 33
q + d = 33 25q + 10d = 6
q + d = 33 0.25q + 0.1d = 6
Answers
Answer:
q + d = 33 0.25q + 0.1d = 6 Option D
Step-by-step explanation:
The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:
q + d = 33
0.25q + 0.1d = 6
Martin has a combination of 33 quarters and dimes worth a total of $6.
Therefore,
q = number of quarters
d = number of dimes
The linear equation can be represented below:0.1 dollars = 1 dime
0.25 dollars = 1 quarters
Therefore,
0.25q + 0.1d = 6
The quarters and dimes total 33. Therefore,
q + d = 33Therefore, the combined equation will be as follows:
q + d = 33
0.25q + 0.1d = 6

For a certain population of sea urchins, 16% are longer than 8 inches. A random sample of 75 sea urchins will be selected. What is the standard deviation of the sampling distribution of the sample proportion of sea urchins longer than 8 inches for samples of size 75?
Answers
Answer:
0.042
Step-by-step explanation:
Given :
p = 16% = 0.16
q = 1 - p = 1 - 0.16 = 0.84
Sample size, n = 75
The standard deviation of sampling distribution :
√(pq)/n
√(0.16 * 0.84) / 75
√0.1344 / 75
√0.001792
Standard deviation of sampling distribution = 0.0423320

The reason is that if you simplified 4/8, you will get 1/2. When you simplified 8/10, you will get 4/5. 1/2 and 4/5 aren't the same number or equivalent to each other so the answer will be no.
