5 to the power of 2 = 25
9 to the power of 2 = 81
25 + 81 = 106
Square root of 106 = 10.29563
If you round it to the nearest hundredth, it will become 10.30
If you round it to the nearest tenth, it will become 10.3
Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92
A should be correct. hope this helped
Answer:
The length would be 32 and the width would be 10
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 22 since we know it is 22 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.
P = 2l + 2w
84 = 2(x + 22) + 2(x)
84 = 2x + 44 + 2x
84 = 4x + 44
40 = 4x
10 = x
Now since we know that the width is 10ft, we can add 22ft to it to get the length, which would be 32ft.
