Rent all
55.5/3 = 18.5
74/4 = 18.5
it costs 18.5 per day
1. y = 18.5 x where y =cost and x=days
A-1
10.99 per 1/2 day
10.99 * 2 =21.98 per day
2. it costs 21.98 per day from A-1
Rentall is the better deal because it is only 18.50 per day versus 21.98 per day
Answer:
Area of equilateral triangle = 81√3 cm²
Step-by-step explanation:
Given:
Perimeter of an equilateral triangle = 54 cm
Find:
Area of equilateral triangle
Computation:
Perimeter of an equilateral triangle = 3 x Side
54 = 3 x Side
Side of equilateral triangle = 54 / 3
Side of equilateral triangle = 18 cm
Area of equilateral triangle = [√3/4]side²
Area of equilateral triangle = [√3/4][18]²
Area of equilateral triangle = [√3/4][324]
Area of equilateral triangle = [√3][81]
Area of equilateral triangle = 81√3 cm²
Answer:
Step-by-step explanation:
12 miles is the ride distance
the guy is able to travel at 6 yard per second
Question C asks how many minutes will the trip take
first we have to convert miles to yards....
there are 1760 yards in one mile
12*1760= the total distance to be traveled.. in yards..
21,120 yards
Next we'll figure out the time to travel that distance.. but we're give a rate of travel in seconds... 6 yards every second
so divide the total yards by the seconds.. that are take to travel every second.. in on second he goes 6 yards. so divide the total yards by 6 for each second of travel
21,120 / 6 = 3520 seconds to go 12 miles or the 21,120 yards.. it's the same distance in different units
then.. b/c the question is asking for minutes divide the 3,520 seconds by 60.. b/c that's how many seconds are in one minute
3,520 / 60 = 58.6666666666666 minutes or 58 minutes and 2/3 of one minute.... make sense?
Answer:
40 cans weigh over 14.7 ounces
Step-by-step explanation:
Given
Mean = 14 ounces
SD = 0.7
We have to find the z-score for 14.7 first
As we have to find the number of cans greater than 14.7, forst we will find the area to the left of obtained z-score and then subtract from 1.
So,
P(z<1) = 0.8413
Now,
P(z>1) = 1 - P(z<1) = 1-0.8413 = 0.1587
As the total number of cans is 250,
The cans which weigh over 14.7 are:
= 0.1587 * 250
= 39.675
Rounding off to nearest whole number
40 cans
Hence,
40 cans weigh over 14.7 ounces
Answer:
168 books
Step-by-step explanation:
Given
of the remaining books
Required
Determine the total number of books
If the proportion of the English books is 3/8, the the remaining is:
Take LCM
From the question, we understand that:
of the remaining books
This means:
From the question, we also understand that 75 are Chinese books.
The total number of books can then be calculated using:
Substitute 75 for Chinese
Make Total the subject:
