To solve the problem we could separate the figure into three parts. First figure is a triangle, second figure is a rectangle, third figure is a triangle. See image attached.
Solve each area of the figuresFirst figure, a triangle that have 7 units long of the base, and 2 units long of the height.
a = 1/2 × b × h
a = 1/2 × 7 × 2
a = 14/2
a = 7
The area of the first figure is 7 units²
Second figure is a rectangle, the length of the rectangle is 7 units, the width of the rectangle is 4 units.
a = l × w
a = 7 × 4
a = 28
The area of the second figure is 28 units²
Third figure is a triangle, the base is 7 units long and the height is 2 units long.
a = 1/2 × b × h
a = 1/2 × 7 × 2
a = 14/2
a = 7
The area of the third figure is 7 units²
The area of the three figuresarea = first figure area + second figure area + third figure area
area = 7 + 28 + 7
area = 42
The total area of the figures is 42 units²
4. is correct
5. A is correct
6. B is correct
Answer:
B
Step-by-step explanation:
Answer:
y = 1.5x + 1
Step-by-step explanation:
→ Choose 2 points
( 2 , 4 ) ( -2 , -2 )
→ Find the gradient
-6 ÷ -4 = 1.5
→ Write into format
y = 1.5x + c
→ Substitute in ( 2 , 4 )
4 = 3 + c
→ Minus 3 from both sides
1 = c
y = 1.5x + 1
Answer:
Discount = .64
New price = 7.31
Step-by-step explanation:
To find the discount, take the price times the discount rate
7.95 * 8%
7.95 *.08
.636
Rounding to the nearest cent
.64
We take 64 cents off
The new price would be
7.95-.64 =7.31
