Answer:
168 books
Step-by-step explanation:
According to problem, given data are as follows:
Total books for sale = 280 books
Sold on first day = 3 out of 5 books
So, percentage of first day sold = 3 ÷ 5 = 0.6 or 60%
So, we can calculate the total books sold on day one by using following method,
Total books sold on first day = Total books for sale × percentage sold
By putting the value, we get
= 280 books × 60%
= 168 books
Answer:
The distance is 
or 
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Answer:
the area of a trapezoid is equal to half the product of the height and the sum of the two bases. Area = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).
I think it will be 91 cm because the area of the square is 49 and the area of the triangles is 14
49+14+14+14=91cm
