Frank paid $22.44 I sweatshirt had been discounted by 30% what is the regular price the sweatshirt
Answer: $32.06
Step-by-step explanation:
Let the regular price of the sweatshirt be x.
Therefore,
$22.44 = x - 0.3x
22.44 = 0.7x
x = about $32.06
Answer:
Step-by-step explanation:
22.44 represent 70% of the normal price of the sweatshirt.
Why 70%?
The reason is if you take 30% of the original price and subtract that from thirty %, you will get 70% of the original price.
Original price = 70% of x
Equation
70% x = 22.44
70/100 x = 22.44 Multiply both sides by 100
70 x = 22.44 * 100
70 x = 2244 Divide both sides by 70
70x/70 = 2244 / 70
x = 32.06
Answer: The sweatshirt originally cost 32.06

Leonardo recorded his speed while skate-
boarding and determined he was traveling
18 feet per second. How many feet could
he travel in one minute?
Answer:
Leonardo was travelling: 1080 feet per min
Step-by-step explanation:
Since we know there are 60 seconds in a minute, we can just multiply 18 by 60 and get the answer as in the problem, it states that he is travelling 18 feet per second.
So the answer would be 18*60 or 1080 feet per minute.

Dante will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $63.96 and costs an additional $0.10 per mile driven. The second plan has an initial fee of $51.96 and costs an additional $0.15 per mile driven. How many miles would Dante need to drive for the two plans to cost the same?
answer: 240 miles
Answer:
Sir it says the answer at the bottom of the question
Step-by-step explanation:
It is 240 and I also did the math (.10 * 240 = 24 + $63.96 = 87.96)
and (.15 * 240 = 36 + 51.96 = 87.96) the answer is 240!

36 cm/sec to mph in dimensional analysis
Answer:
There are 2.54 centimeters in an inch. There are 63,360 inches in a mile. So, there are 160,934 centimeters in a mile. There are 3600 seconds in an hour.
36 cm/sec is 36 times 3600 cm/hour = 129,600 cm/hour. Therefore, there are 129,600/160,934 miles per hour = 0.80529 mph
Step-by-step explanation:

The speed from centimeters per second to miles per hour will be 0.805 miles per hour.
What is conversion?Unit modification is the process of converting the size of a given amount between different units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
The speed is given below.
Speed = 36 cm per second
We know that in 1 centimeter, there are 1 / 160934 miles. And in one second, there are 1/3600 hours.
Then convert the speed from centimeters per second to miles per hour. Then we have
Speed = 36 x (1/160934) ÷ (1/3600)
Speed = 36 x 3600 / 160934
Speed = 129600 / 160934
Speed = 0.805 miles per hour
The speed from centimeters per second to miles per hour will be 0.805 miles per hour.

use the internet more than 15 hours per week.
Based on the data, if the company has 800
subscribers how many watch more than 10 hours
per week?
Answer:
448 subscribers
Step-by-step explanation:
First, find the percentage of people that use the internet more than 15 hours per week.
[tex]\%=\frac{28}{50}=0.56=56\%[/tex]
Now, we can use this information to find 56% of 800.
[tex]56\%*800[/tex]
Note that percentages can also be written as that number over 100.
