Answer:
Step-by-step explanation:
The ratio 19/25 is the same as 76/100, or 0.76.
Multiplying this by 100%, we get 76%, the percentage of questions answered correctly.
Subtracting 76% from 100% results in 24%, which is the percentage of questions not answered correctly.
Answer:
1) A = 27 square units, P = 24 units; 2) 276 mm; 3) A = 8, B = 4, C = 3, D = 5, 108 square feet; 4) 5.
Step-by-step explanation:
1) The sides of the rectangle are 9, 9, 3, and 3.
2) 40 + 40 + 70 + 70 + 28 + 28
3) 32 + 6 + 6 + 24 + 40 = 108
4) 24 + 24 + 20 + 20 + 30 + 30 = 148
740/148 = 5
2. 2 5/12
4. 1 1/6
5. 1 1/2
6. 1 1/12
7. 1 5/12
8. 1 1/2
9. 1 7/12
10. 1 5/8
Answer:
1.2
Step-by-step explanation:
9/5*2/3=1.2
Number of swings = x
Number of slides = y
First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x
Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250
Based on this:
The correct choices are: b and d</span>
