1/12 is the answer i think
Answer:
Calvin has $100 more at the end of June than at the end of February.
Step-by-step explanation:
Consider the provided graph line graph.
From the line graph it can be observed that, the saving account balance of Calvin in the end of February is around $175.
The saving account balance of Calvin in the end of June is around $275.
Refer the figure 1.
Now to find how much more money did Calvin have in his account at the end of June than at the end of February simply subtract the greater number from the smaller.
275
<u>- 175 </u>
<u> 100</u>
Hence, Calvin has $100 more at the end of June than at the end of February.
Answer:
Length = 4 feet
Width = 4 feet
Step-by-step explanation:
The perimeter of a rectangle formula = 2L + 2W
Where L = Length
W = Width
The length of a rectangle is 8feet less than the width.
Hence,
L = 8 - W
The perimeter is 64 feet.
Hence,
64 = 2(8 - W) × 2W
64 =( 16 - 2W )2W
64 = -4W² + 32W
4W² - 32W + 64 = 0
Factorise
4W² - 16W - 16W + 64 = 0
4W (W - 4) - 16(W - 4) = 0
W - 4 = 0
W = 4
Width = 4
Solving for L
L = 8 - W
L = 8 - 4
L = 4
Therefore,
Length = 4 feet
Width = 4 feet
