Answer:
Step-by-step explanation:
First calculate the amount of notebooks and textbook
Cost of 2 notebooks = 2 *8.75
= $ 17.5
Cost of 1 textbook = $ 74.95
Total cost = 17.5 + 74.95
= $ 92.45
Tax = 7% of total cost
= 0.07 * 92.45
= $ 6.47
Total cost = 92.45 +6.47
= $ 98.92
Answer:
The area of the rectangle is 40 and the area is the triangle is 20 therefore, the area of the shape is 60
Step-by-step explanation:
Rectangle:
8cm x 5cm = 40cm
Triangle <em>(</em><em>1</em><em>/</em><em>2bxh</em><em>)</em>
The base of the triangle would be 8 cm as the top and the bottom of the rectangle is the same width. The height was given to be 5 cm (<em>note the height is the dotted line</em>) Therefore the area of the triangle is half the base which is (8×1/2 = 4) times the height (5); which is 20.
