Answer:
f. 260 in by 100 in
Step-by-step explanation:
13 + 5 = 18
720/18 = 40
Find length:
40*13 = 520
520/2 = 260 <-- must divide by 2, 520 is the sum of twice the length
Find width:
40*5 = 200
200/2 = 100 <-- must divide by 2, 200 is the sum of twice the width
Let...
l=length
w=width
Because we know that the perimeter is 90, we can make this equation...
2l+2w=90
Because we know that the length is 5 feet less than 4 times the width, we can make this equation...
l=4w-5
We can solve this system through substitution...
2(4w-5)+2w=90
8w-10+2w=90
10w=100
w=10 ft
l=4(10)-5=35 ft
Answer: The answer would be 1
Step-by-step explanation:
Rise over run or fall over run so the fall is 10 and run is 10 and 10/10 is 1.
4/9 *9/4 =1
Use the reciprocal to find your answer :)

The student that did more maths problems per minute is Diedra.
In order to determine which student did more maths problems per minute, the rate of each student has to be determined. Rate is the total questions solved divided by the time.
Rate = total questions / total time
Malcolm = 15 / 18 = 0.833 problems per minute
Diedra = 16/ 17 = 0.941 problems per minute
