Answer:
1) Incomplete question
2) Scatterplot
Step-by-step explanation:
1) The question is incomplete. To calculate the average time required for the toy car to move, the formula to be used will be
velocity = distance ÷ time
Hence; time = distance ÷ velocity
2) There are two variables in the question; the distance (it takes the ball to fall) and the time. The type of graph (from the option) that can have two variables represented on it is a scatterplot.
Answer:
a) 80.35m^2
b)2 and 18
C)4.8
D)200% of 7=14
7 decreased by 200=-7
Step-by-step explanation:
Answer:
Andrew is 30 years old. Hunter is 65 years old.
Step-by-step explanation:
we can set up 2 equations:
h = 35 + a
h+5 = 2(a+5)
Solve for h in the second equation.
h + 5 = 2a + 10; h = 2a + 5
now set the 2 equations = to each other
2a + 5 = 35 + a
solve for a by combining like terms
a + 5 = 35
a = 30
so Andrew is 30 and Hunter is 35 + 30 = 65.
Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)
