Answer:
Please check the explanation.
Step-by-step explanation:
We know the equation
y = kx
k = y/x
where k is the proportionality constant
so,
First ratio can be calculated as
Miles = 45
Hours = 3/4
The ratio = 45 / (3/4)
= (45 × 4) / 3
= 180/3
= 60
Thus, the proportionality constant = 60
Thus, the remaining ratios can be calculated as:
The Pair (135, Hours)
135/Hours = 60
Hours = 135 / 60
= 27/12
= 9/4
= 2.25
Thus, the pair is (135, 2.25)
The Pair (Miles, 3)
Miles/3 = 60
Miles = 60×3
= 180
The Pair (90, Hours)
90/Hours = 60
Hours = 90 / 60
= 3/2
= 1.5
Thus, the complete table:
Miles 45 135 180 90
Hours 3/4 9/4 3 3/2
Verification:
Miles / Hour = 45/(3/4) = 60
Miles / Hour = 135 / 2.25 = 60
Miles / Hour = 180 / 3 = 60
Miles / Hour = 90 / 1.5 = 60
24% of 80 is 19.2
120% of 70 is 84
20% of 150 is 30
0.8% of 150 is 1.2
120% of 85 is 102
81 more than x
more than means add
81 more than x
x+81 or 81+x
Answer:
x = 110°, y = 110°
Step-by-step explanation:
y = 110° ( vertical to 110° )
x = 110° ( alternate angle to y )
<span>1. 15 is what percent of 40?
15 * 100 / 40 = 37.5
answer is </span><span>15 is 37.5% of 40
</span><span>
2. 15 is 30% of what number?
15 / 0.3 = 50
answer : </span>15 is 30% of 50<span>
3. What number is 120% of 70?
120% = 1.2
1.2 + 1 = 2.2
2.2 * 70 = 154
answer: 154</span> is 120% of 70?<span>
