5 feet = 60 inches
Sarah needs to grow 6 more centimeters.
Answer:
The dimensions are 25 * 50 feet.
Step-by-step explanation:
The 3 sides of the pen will measure (2x + y) feet where x is the width and y is the length.
2x + y = 100
y = 100 - 2x
The area A = xy = x(100 - 2x) ft^2.
Finding the maximum area.
A = x(100 - 2x)
A = 100x - 2x^2 Finding the derivative:
A' = 100 - 4x
For maximum value of A this equals zero:
100 - 4x = 0
4x = 100
x = 25 ft, so this is the width.
The length is 100 - 2(25) = 50 ft.
Answer:
a.
i. 11
ii. 26
iii. 501
iv. 3.5
v. 5a+1
vi. 5k+6
b. x = 8
Step-by-step explanation:
Answer:
1. 244
2. 122
3. 61
Step-by-step explanation:
1. 244 because I divided 488 by 2.
2. Divide 244 by 2.
2. Divide 122 by 2.
The 3 in 350 represents 300
because 350=300+50+0, that is: 3 one hundreds +5 tens +0 ones
The 3 in 403, represents 3 because 403 = 400+3 that is 4 one hundreds, 0 tens and 3 ones.
Thus the 3 in the number 350 and the 3 in the number 403 are not the same.
The 3 in the number 350 is one hundred time the 3 in the number 403.
Answer: The 3 in the number 350 is one hundred time the 3 in the number 403.
