Answer:
= 0.38 m/s
Step-by-step explanation:
▪Total distance = 800 m
5 min = 100 m
▪Remaining distance = 800 - 100 = 700 m
20 min = 700 m
▪Total time taken = 20 + 10 + 5 = 35 min
If 1 min = 60 sec
What about 35 min = ?
= 35 x 60
= 2100 sec
▪Average speed = TD ÷ TT
= 800 ÷ 2100
= 0.38 m/s
Answer:
<u>Cora spent $ 30</u>
Step-by-step explanation:
1. This is the information given to us to answer the question correctly:
x = Amount of money Ben spent
3x = Amount of money Ava spent (Ava spent three times as much as Ben)
6x = Amount of money Cora spent (half as much as Cora)
2. If together they spent a total of 50, how much did Cora spend?
Let's solve for x, this way:
x + 3x + 6x = 50
10x = 50
x = 50/10
x = 5
In consequence,
Ben spent $ 5 (x)
Ava spent $ 15 (3x)
<u>Cora spent $ 30 (6x)</u>

Answer:
Step-by-step explanation:
area of a circle=πr^2
42=3.14*r^2
42/3.14=r^2
13.37=r^2
=r
3.65=r
3.7=r
therefore radius of a circle is 3.7 ft
