Last week, the Bay City Bus Company tracked how long their school buses took to complete their routes. This box plot shows the results. Length of route (min.) 24 26 28 30 32 34 What percent of the buses completed their routes in 27 to 30 minutes?
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Plot: \{24, 26, 28, 30, 32, 34\}[/tex]
Required
Determine the percentage of those who uses the bus for 27 to 30 mins
The box plot is not given. So, I will make assumptions in order to solve this question.
Assume the following readings from the box plot:
[tex]Total\ Buses= 60[/tex]
[tex]27-30\ Minutes = 20\ buses[/tex]
Using these assumptions, the required percentage is:
Total = 6
27 to 30 minutes = 2
[tex]Percent = \frac{27\ to\ 30\ mins}{Total} * 100\%[/tex]
[tex]Percent = \frac{20}{60} * 100\%[/tex]
[tex]Percent = \frac{2000}{60} * \%[/tex]
[tex]Percent = 33.33 * \%[/tex]

Rick wants to buy a tool set with an original price of $165. Next week, the tool set will be on sale for $40 off. What is the sale
price of the tool set?
Answers
Answer:
$125 is the sale price.
Step-by-step explanation:
Answer:
24.24% off
Price of tool set: $125
Step-by-step explanation:
$40 is the price change
You can divide 40 by the original price which is 165 and then multiply by 100 to get your percentage change.
40 / 165 = 0.2424
0.2424 * 100 = 24.24
So there is 24.24% discount.
The equation $(x - 7)^2 + (y + 13)^2 = 12$ represents a circle. What is its radius?
Answers
Answer:
2√3Step-by-step explanation:
The standard equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the center of the circle
r is the radius of the circle
Given the equation (x - 7)^2 + (y + 13)^2 = 12
On comparing;
r² = 12
Take the square root of both sides
√r² = √12
r = √12
r = √4*3
r = 2√3
Hence the radius of the circle is 2√3
Answer: 2 sqrt 3

A new energy drink advertises 130 calories for 6 oz. How many calories are in 18oz of the drink?
Answers
Answer:
390 calories
Step-by-step explanation;
18/3=6
130 x 3 = 390
Answer:
390
Step-by-step explanation:
You can set up a simple ratio, 130 is to 6 as x is to 18. Notice how 6x3=18 so since you multiplied the 6 by 3, then multiply the 130 by 3, so 130 x 3 = 390 calories
Is 13:15 and 30:26 a pair of equivalent ratios and why?
Answers
Given:
The two ratios are 13:15 and 30:26.
To find:
Whether the given ratios are equivalent or not.
Solution:
Two ratios are equivalent if the values of the ratio are equal after simplification.
[tex]13:15=\dfrac{13}{15}[/tex]
And,
[tex]30:26=\dfrac{30}{26}[/tex]
[tex]30:26=\dfrac{15}{13}[/tex]
[tex]30:26=15:13[/tex]
The first ratio is 13:15 and the value of second ratio after simplification is 15:13 both ratios are different, so,
[tex]\dfrac{13}{15}\neq \dfrac{30}{26}[/tex]
Therefore, the required answer is "No", the given ratios are not a pair of equivalent ratios.
