Answer:
The sum of the amounts Kelvin will pay over the next three months is $42
Step-by-step explanation:
[tex]\begin{table}[]\begin{tabular}{lllll}Month & Amount & & & \\1 & \$14 & & & \\2 & \$14 & & & \\3 & \$14 & & & \\Sum & \$42 & & & \end{tabular}\end{table}[/tex]The given parameters are;
The monthly cost of Kelvin's Netflix plan = $14
The number of months over which the sum of the amount paid is calculated = 3 Months
The table that represents the parameters above is as follows;
[tex]\left\begin{array}{ccc}Month \ Number && Amount \ Payed \\\\1&& \$14.00\\2&&\$14.00\\3&&\$14.00\\\\ Sum \ of \ Amount&&\$42.00\end{array}\right[/tex]

A walking track is 2 1/2 miles long. How many feet is that?
Answer:
13,200 feet
Step-by-step explanation:
Answer:
13,200 feet
Step-by-step explanation:
In one mile, there are 5,280 feet.
You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.
X = the number of feet in 2.5 miles.
[tex]\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}[/tex]
To find X, all you need to do is cross multiply.
So,
X = 5280 × 2.5 = 13,200 feet

Obasi earns 150\%150%150, percent of his regular hourly wage while working overtime. What fraction of his regular hourly wage does Obasi earn while working overtime?
Answer:
3/2 or 1 1/2
Step-by-step explanation:
We are told that:
Obasi earns 150% of his regular hourly wage while working overtime
The fraction of his regular hourly wage that Obasi earns while working overtime is written as:
150%
= 150/100
= 15/10
= 3/2
= 1 1/2
The fraction of his regular hourly wage that Obasi earns while working overtime is 3/2 or 1 1/2

Isabella is deciding between two parking garages. Garage A charges an initial fee of
$4 to park plus $3 per hour. Garage B charges an initial fee of $12 to park plus $2 per
hour. Let A represent the amount Garage A would charge if Isabella parks for t
hours, and let B represent the amount Garage B would charge if Isabella parks fort
hours. Write an equation for each situation, in terms of t, and determine the hours
parked, t, that would make the cost of each garage the same.
Answer:
1. A = 4 + 3t ............ 1
B = 12 + 2t .............. 2
2. 8 hours
Step-by-step explanation:
For park A,
A = 4 + 3t ............ 1
where A is the amount paid, and t is the number of hours.
For park B,
B = 12 + 2t .............. 2
where B is the amount paid, and t is the number of hours.
The hours that would make A = B can be determined as follows.
Equate 1 and 2, so that;
A = B
4 + 3t = 12 + 2t
collect like terms
3t - 2t = 12 - 4
t = 8
The number of hours that would make the cost of each garage the same is 8.
Answer:
A= 3t+4
B= 2t+12
3t+4=2t+12
t= 8 hours
Marcus spent 2 hour reading,1 hour playing Rocket League,and took a 2 hour nap. What percent of the total time did he read?
Answer: He read 40% of the total time.
Step-by-step explanation:
As per given,
Total time he spent = 2 +1+2 = 5 hours
Number of hours he spent on reading = 2 hours
The percent of the total time he read = [tex]\dfrac{\text{Number of hours read}}{\text{Total time spent}}\times100[/tex]
[tex]=\dfrac{2}{5}\times100\\\\=40\%[/tex]
i.e. The percent of the total time he read = 40%
Hence, he read 40% of the total time.

If there are 22 successes in a sample with a size of 40, what is the sample
proportion?
A. 0.55
B. 0.65
C. 0.44
D. 0.22
Answer:
A
Step-by-step explanation:
22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.
22/2 = 11
40/2 = 20
Now you have 11/20. Put this in decimal form and you have 0.55
Option A answer is 0.55
What is the proportion of a sample?The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.
The solution to the given problemThe size of the sample is 40.
There are 22 successes in the sample.
To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55
Hence option A is correct, the proportion is 0.55
