Answer: 3 miles per hour
<u>Step-by-step explanation:</u>
Use the formula "distance (d) = rate (r) x time (t)" to create a system of equations.
Let "r" represent the rate they are rowing
Let "c" represent the current
time rate distance <u>EQUATION</u>
Downstream: 4 hours r + c 40 miles 4(r + c) = 40
Upstream: 10 hours r - c 40 miles 10(r - c) = 40
Distribute, then eliminate r to solve for c:
Down: 4r + 4c = 40 → 5(4r + 4c = 40) → 20r + 20c = 200
Up: 10r - 10c = 40 → -2(10r - 10c = 40) → <u>-20r + 20c</u> =<u> -80</u>
40c = 120
<u> ÷40 </u> <u>÷40 </u>
c = 3
Hello there!
The larger integer is 114.
x + (x + 2) = 226
Combine like terms
2x + 2 = 226
Subtract 2 from both sides
2x = 224 Divide
x = 112
The two integers are 112 and 114. But they asked us for the lager integer. So 114 is the answer.
I hope this helps! As always, it is my pleasure to help students like you!
Answer:
The ratio of circumference of circle and diameter of circle is π
B is correct
Step-by-step explanation:
The radius of a circle is 6.
We need to find the ratio of circumference of circle and diameter
Circumference of circle = 2πr
C = 12π
Diameter of circle = 2r
D = 12
Substitute 12 as D
Now we find the ratio of circumference and diameter
Hence, The ratio of circumference of circle and diameter of circle is π
