Answer:
P (3,4) Q (6,7)
Count the units for each letter
Answer:
There are 102 coins total:
34 Quarters
20 loonies
48 toonies
Step-by-step explanation:
Assuming money is counted in coins instead of value, it can be solved like this.
1. find a common denominator for 1/3 and 1/5. We can use 15. So, of the money collected, 5/15 were quarters and 3/15 were loonies. This makes 7/15 toonies. If there are 48 toonies, we can divide this by 7 to find the value of 1/15. 48/7 = 6 6/7. Multiply this number by 15 (for each value) and you get 102 6/7.
There are 102 coins total:
34 Quarters
20 loonies
48 toonies
Answer:
the solution set is r>7
step by step:
Subtract 3 from both sides
3−3r−3<−2r−4−3
Simplify
−3r<−2r−7
Add 2r to both sides
−3r+2r<−2r−7+2r
Simplify
−r<−7
Multiply both sides by −1 (reverse the inequality)
(−r)(−1)>(−7)(−1)
Simplify
r>7
First calculate the future value
The formula is
A=p (1+r/k)^kt
A future value?
P present value 6599.2
R interest rate. 0.042
K compounded monthly 12
T time 7 years
A=6,599.2×(1+0.042÷12)^(12×7)
A=8,850.16
Now calculate the interest earned
I=A-p
I=8,850.16−6,599.2
I=2,250.96
Hope it helps!
