When you divide fractions, you want to use keep change flip.
You keep the 1st fraction, change the division sign into a multiplication sign, then flip the last fraction.
Let’s use 3/4 ÷ 2/3
Keep 3/4 the same, change the division sign into a multiplication sign, and flip 2/3 so that it is 3/2
It’ll look like this
3/4 x 3/2
Now just multiply the numerators, 2 x 3, then multiply the demoninators, 4 x 2.
You get 6/8
Simplify this number and you get 3/4.
If you have any further questions feel free to ask.
Hope this helps.
Answer:
A) 0.4255
B) 0.5813
C) 0.5588
D) 0.7241
Step-by-step explanation:
Assuming that the probability for each case is the same, we can calculate the probability by dividing the number of favourable cases with the total amount of cases. You can find the total amount of cases by adding the favourable ones with the non favourable ones, so, the probability of each case would be:
A) 20/(27+20) = 20/47 = 0.4255
B) 25/(18+25) = 25/43 = 0.5813
C) 19/(15+19) = 19/34 = 0.5588
D) 21((8+21) = 21/29 = 0.7241
If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:

You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.

This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is: 
So we can plug our dimensions into the formula: 
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is: 
We can plug our dimensions into the formula: 
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
Answer:
s(2) = √7
Step-by-step explanation:
s(2) = √(3[2] + 1) = √7
Answer:
Step-by-step explanation:
w (width) = 32/8
w = 4
p (perimeter) = 2w + 2l
p = (2 x 4) + (2 x 8)
p = 8 + 16
p = 24
