The answer would be 9.9
Pemdas
9.7-2.4= 7.3
2.6+7.3 = 9.9
Answer:
(-2,-3)
Step-by-step explanation:
I took the test and got it wrong at first but seen the correct answer when I looked at my results.
Answer:
9
Step-by-step explanation:
Ratio of areas = (Ratio of sides)²
2025/25 = (feet/inch)²
sqrt(2025/25) = feet/inch
feet/inch = 9
Answer:
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
Step-by-step explanation:
Let x = the rate of the boat in still water and y = the rate of the current.
Distance traveled = 24 miles
Time taken for upstream motion = 2 hour
Time taken for downstream motion = 1.5 hour
Velocity of upstream motion = x - y
Velocity of downstream motion = x + y
We have
Displacement = Time x Velocity
Upstream motion
24 = 2(x-y)
x - y = 12 ----------------------------eqn 1
Downstream motion
24 = 1.5(x+y)
x + y = 16 ----------------------------eqn 2
eqn 1 + eqn 2
2 x = 28
x = 14 miles per hour
Substituting in eqn 2
14 + y = 16
y = 2 miles per hour
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
