Answer:
Step-by-step explanation:
3/4- 1/28
3(7)/4(7)= 21/28-1/28
=20/28
=5/4
44% bc 50 is half of 100 so u would multiply 22•2 bc 2 is half and u would get 44 then add ur percentage
Answer:
The surface area of the prism is 72 square units.
Step-by-step explanation:
In order to calculate the surface area of the prism we must calculate the area of each face of the prism. To better visualize it we can look at the picture below. We must calculate the area of every face in the picture, so we have:
surface area = 2*[(1/2)*3*4] + 3*5 + 4*5 + 5*5
surface area = 12 + 15 + 20 + 25
surface area = 72 square units
The best estimate would be (-1)(1/2)(-1)(1)
Why?
(-4/5) = Really close to -1. The fraction -5/5 would = -1
(3/5) = Really close to 1/2
(-6/7) = Really close to -1. It is just -1/7 from being from -1
(5/6) = Really close to 1. It is just 1/6 from being 1
Answer:
Price of senior citizen ticket = $7
Price of student ticket = $5
Step-by-step explanation:
<u>Let</u>:
- senior citizen ticket price = a
- student ticket price = b
<u>Equations formed</u> :
- 9a + 10b = 113
- 2a + 10b = 64
<u>Subtract</u> : Equation 1 - Equation 2
- 9a + 10b - 2a - 10b = 113 - 64
- 7a = 49
- a = 7
<u>Finding b</u>
- 2(7) + 10b = 64
- 10b = 50
- b = 5
<u>Solution</u>
- Price of senior citizen ticket = $7
- Price of student ticket = $5
