Answer:
Hakims car travels 600 feet in 20 seconds. Andres mortar cycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle?
The car is faster
Find the unit rates
The car is going 30 feet in 1 second(600 divide by 20 = 30)
The motorcycle is gonig 25 feet in 1 second(300 divide by 12 = 25)
Compare the unit rates
30 > 25
Step-by-step explanation:
20/52 = b/100
20 x 100/52 x b
2000/ 52b
b = 38.5
Explanation:
b is a variable that stands for the unknown quantity
Write 20/52 as equal to b/100
Next we cross multiply 20 by 100 = 2000 and 52 by b = 52b
2000/52b is equal to 38.46 but roundest to the nearest tenth it is 38.5
Answer:
Step-by-step explanation:
hello :
-2x+5y=39
....(*)
2x-3y=-25....(**)
add(*) and (**) : 2y =64 so : y =64/2 = 32
put this value in (*) : -2x+5(32) = 39 ....continu
The cost will be same for one session. The cost will be $128.
Step-by-step explanation:
Given,
Initial consultation charges for Plan One = $36
Per session fee = $92
Let,
x be the number of sessions.
O(x) = 92x+36
Initial consultation charges for Plan Two = $86
Per session fee = $42
T(x) = 42x+86
For same cost;
O(x) = T(x)
Dividing both sides by 50
Putting x=1 in T(x)
Putting x=1 in O(x)
The cost will be same for one session. The cost will be $128.

Answer: A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
Step-by-step explanation:
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.
