Answer:
Each shirt is $8
Step-by-step explanation:
80÷10 = 8
Answer:
18
Step-by-step explanation:
To eliminate the fraction, multiply by 2 both sides of the equation. This gives,
2A = h x (b1 + b2)
Then, divide both the left hand and the right hand side of the equation by the variable h.
2A / h = b1 + b2
Next, subtract b1 from both sides,
(2A / h) - b1 = b2
Rearranging the equation,
b2 = (2A/h) - b1
Because x represents the number of hours, we can replace the value of x with how many hours have elapsed to see how many pages the typist has typed.
y = 5x
y = 5(2.3)
y = 11.5
<h3>The typist can type 11.5 pages in 2.3 hours.</h3>
Answer:
Area:
Perimeter: 20
Step-by-step explanation:
If we take half of one of these "pedals" we can see that it is simply 1/4 of a circle with radius 5, subtracted by a triangle. Let's calculate this half-pedal.
That means 4 pedals is equal to:
So.. The area of the shaded region is
Perimeter is even simpler. the half-pedal is just 1/4 of the circumference of the circle. The circumference is just , which means our half pedal is:
Multiplying by 8, our perimeter is just 20.
