Answer:
6 1/2 minutes per miles
2/13 miles per minutes
Step-by-step explanation:
Distance travelled = 2 1/2 miles
Time taken = 16 1/4 minutes
Average: minutes per mile
= 16 1/4 minutes / 2 1/2 miles
= 65/4 ÷ 5/2
= 65/4 × 2/5
= 13/2
= 6 1/2
Average time per mile in minutes
= 6 1/2 minutes per mile
Average (miles per minutes)
= 2 1/2 ÷ 16 1/4
= 5/2 ÷ 65/4
= 5/2 × 4/65
= 20 / 130
= 2/13 miles per minutes

What single percentage change is equivalent to a 12% increase followed by a 14% decrease?
Answer:
3.68% decrease
Step-by-step explanation:
12% increase = 112% of the original value
112% as a decimal = 112/100 = 1.12
14% decrease = 100% - 14% = 86% of the original value
86% as a decimal = 86/100 = 0.86
Therefore, if you increase the number n by 12% and then decrease by 14%:
n × 1.12 × 0.86 = n × 0.9632
0.9632 as a percentage = 0.9632 × 100 = 96.32%
Therefore, the overall percentage change is 100% - 96.32% = 3.68% decrease

A literary agent makes $30,000 a year plus 13% commission on the sales of her clients' books to publishers. The agent sold 4 books for $175,000 each for her
clients this year.
Find her total earnings.
Answer:
She made $121000.
Step-by-step explanation:
The money the agent sold was:
4*175000=700000 (dollars)
but she only gets 13% of this, so she earned:
700000*0.13=91000 (dollars)
She also makes $30000 per year, so the total income she earned was:
91000+30000=121000

Jane made $108 for 9 hours of work.At the same rate, how many hours would she have to work to make $216?
pls help
Answer:
18 hours
Step-by-step explanation:
$108 = 9 hours
$216 = x hours
we want to get to $216 from the original equation. one thing we can do to get there is to figure out what we need to multiply 108 by to get 216. to figure this out, we can calculate 216/108 = 2.
therefore, we can multiply both sides of the original equation by 2 to get
$216 = 9 * 2 hours = 18 hours as our answer

A group of students collected old newspapers for a recycling project. The date shows the mass, in kilograms, of old newspapers collected by each student. What percent of students collected between 49 kilograms and 98 kilograms of newspapers?
The percentage of students who collected more than 49kg and less than 98kg of old newspapers is 54.54%
How to calculate the percentage of students who collected more than 49kg and less than 98kg?
To calculate the percentage of students who collected between 49kg and 98kg of old newspapers we must perform the following operations:
We must count how many students are in the range of 49kg to 98kg of old newspapers: 12 students out of 22 students.
100 ÷ 22 = 4.54%4.54 × 12 = 54.54%So, those 12 students are equivalent to 54.54% of students.

∠A and ∠B are complementary. The measure of ∠A is 32°. What is the measure of ∠B? Enter your answer in the box. °
Answer:
∠B = 58°
Step-by-step explanation:
∠A and ∠B are complementary.
-> ∠A + ∠B = 90°
-> 32° + ∠B = 90°
-> ∠B = 90° - 32°
-> ∠B = 58°
Answer:
<B = 58
Step-by-step explanation:
complementary angles are angles that sum up to 90°.
If A and B are angle when added will form 90°, to find B we follow the following steps
A + B = 90
if A = 32°,
32 + B = 90
collect like terms
B = 90 - 32
B = 58
that means
32 + 58 = 90
B = 58

The probability of selecting a shower gel given item is scented must be the same as grabbing shower gel which is 42%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Juanita has a storage closet at her shop with extra bottles of lotion and shower gel, some are scented and some are unscented.
If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel.
For the events "shower gel" and "scented" to be independent.
P(A|B) = P(A)
P(B|A) = P(B)
P(A∩B) = P(A) × P(B)
We know that the probability she selects a shower gel is 42%. Let this event be A. Then we have
P(shower | scented) = P(shower gel) = 42%

What is the measure of DA? (in a parallelogram)
Answer:
DA = 24
Step-by-step explanation:
the opposite sides of a parallelogram are congruent , then
CD = BA , that is
5x - 18 = 2x + 12 ( subtract 2x from both sides )
3x - 18 = 12 ( add 18 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Then
CB = 3x - 6 = 3(10) - 6 = 30 - 6 = 24
so
DA = CB = 24
