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
2) 2/7 divided 1/3 = 6/7
3) 4/9 times 3/8 = 1/6
4) 5/8 times 2/15 = 1/12
5) 1 divided 3/4 = 1 1/3
6) 1/8 times 8 =1/64
7) 2 1/4 times 1/6 = 3/8
8) 5/8 times 2 2/3 = 1 2/3
9) 1 1/8 times 4 = 4 1/2
10) 2 1/5 divided 11 = 1/5
11) 4 1/2 times 1 1/3 =6
12) 2 1/7 divided 3 3/7
13) 2 2/9 times 7 = 16
Always stay not matter what happens if you change you will loose
The last inequality will work because if n is equal to four, then she will earn $28 in total (7*$4=$28). Add that to the $8 that she saved and you get $36, just enough for the coat she wants to buy.
Answer:
2- 96, 3- 203.5
Step-by-step explanation:
2- 9 x 8 + (10 x 8)/2 = 96
.
3- 12 x 18 - (5 x 5) / 2 = 203.5
