Answer:
16 square feet was left over after he cut out the windows
Step-by-step explanation:
The formula of the area of a rectangle is A = l × w, where
- l is the length of the rectangle
- w is the width of the rectangle
∵ The dimensions of each window are 8-foot by 4-foot
∴ l = 8 feet and w = 4 feet
→ By using the rule above find the area of each window
∵ A = 8 × 4
∴ A = 32 feet²
∴ The area of each window = 32 feet²
∵ He cut 2 windows
∴ The area of the 2 windows = 2 × 32
∴ The area of the 2 windows = 64 feet²
∵ The area of the wall is 80 feet²
→ To find the area of the wall left, subtract the area of the windows from
the area of the wall
∵ The area left = 80 - 64
∴ The area left = 16 feet²
∴ 16 square feet was left over after he cut out the windows
Here the points are(-3,-1) and (5,-1)
To find the average rate of change, we have to use the following formula .
Here x1 =-3, y1=-1, x2=5,y2=-1
So we get
Average rate of change=
So the average rate of change from x=-3 to x=5 is 0
Answer:
1). x > 4/3 2). x > 2
Step-by-step explanation:
1). 3x - 91 > -87 2). 17x - 16 > 18
3x > 4 17x > 34
x > 4/3 x > 2
Hope this helps)))
Answer:
7
Step-by-step explanation:
AB//CD (Opposite sides of parallelogram are parallel)
Angle A + Angle B = 180 (Sum of interior angles=180)
138 + 7x - 7 = 180
7x - 7 = 180 - 138
7x = 42 + 7
7x = 49
x = 49/7
x = 7
Answer:
Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.
Step-by-step explanation:
First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:
For 2006 we have:
103+297+210+213+137 = 960 total sales
For 2007 we have:
127+223+210+285+259 = 1104 total sales
The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:
For the total number of coats we have that the percent increase is: %
For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: %
Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:
23.3 % - 15% = 8.3%
