Answer:
46.7 and 93.3 (both 1 d.p.)
Step-by-step explanation:
With ratio, you can turn the numbers of 1 and 2 to their fractional forms
First, 1 + 2= 3
They can be shared as,
1/3 and 2/3
1/3 x 140 gives the share of the 1 in 1:2
2/3 does the same for its share
They both give decimals
140 x 1/3 = 46.67 (rounded to 2 d.p.)
140 x 2/3 = 93.33 (2d.p.)
Answer:
50% of the scores are between 65 and 88
Step-by-step explanation:
taking the diagnostic too
Let the constant be k.
For an inverse squared proportion the formula is y = k/x^2
Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48
After 10 weeks, they will have same amount of money.
Step-by-step explanation:
Given,
Amount Andy have = $20
Amount earned per week = $5
Let,
x be the number of weeks.
y be the total cost.
y = 20+5x Eqn 1
Amount Jennifer have = $50
Amount earned per week = $2
y = 50+2x Eqn 2
For the same amount of money, the equations will be equal.
Eqn 1 = Eqn 2
Dividing both sides by 3
After 10 weeks, they will have same amount of money.
