Laura and Brent paddled a canoe 6 miles upstream in four hours. The return trip took three hours. Find the rate at which Laura and Brent paddled the canoe is still water.
Answers
upstream you have: vs-v=6/4
downstram you have: vs+v=6/3
where v is the rate with which the river flows.
rearranging:
vs-v=3/2
vs+v=2
from the second you have v=2-vs substitute into the first:
vs-2+vs=3/2
2vs=7/2
vs=7 mi/hr

Answer:
36 km
Step-by-step explanation:
This is a right triangle so we can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
27^2+ b^2 = 45^2
729+b^2 =2025
Subtract 729 from each side
729-729+b^2 =2025-729
b^2 =1296
Take the square root of each side
b =sqrt(1296)
b=36
Answer:
36
Step-by-step explanation:
a2+b2=c2
a2+27^2=45^2
a2+729=2025
a2=1296
then square root that number to get
a=36

The balance of Nick's bankaccount is $86.
Concept:
- As we have the bank balance after deducting the check amount and bank charges, we will add those amounts to the balance to get the initial bank balance.
How to solve this question?
- Amount of Check = $30
- Amount of Bank Charges = $35
- Amount after deduction of Check and bank charges =$21
- ∴ Initial bank balance = 21 + 30 + 35 = $86
Thus ,the balance of Nick's bank account is $86.

= (2.50 + 0.02)(3.00 + 0.40)
= 2.50 x 3.00 + 2.50 x 0.40 + 0.02 x 3.00 + 0.02 x 0.40
= 7.500 + 1.000 + 0.060 + 0.008
