The correct answer is 1.4 or 1 4/10

I did this by turning 7/10 into a decimal which is 0.7.

Now I just add 0.7 + 0.7.

For that equation i got 1.4

This would equal 1 4/10

A cyclist rides her bike at a rate of 9 kilometers per hour. What is the rate in kilometers per minute? How many kilometers will
aliya0001 [1]

Answer: 0.15km/min and 0.3km in 2 mins

Step-by-step explanation:

Given Data:

Cyclists speed = 9km/hr

1. Some traveling 60 km/h is traveling one km/min

60/60= 1 km/min

Rate in km/min

= 9km/hr / 60min

= 3/20 km/min

= 0.15 km/min

Kilometers travelled in 2mins

= 2 / 60

= 1 / 30

= 9km/hr * 1 / 30

= 9 / 30

= 0.3 km in 2mins

Find rhe volume of a cylinder with a diameter of 10 inches and a height of 20 inches
IrinaK [193]
Since the diameter of the cylinder is 10, its radius is half that, or 5, thus

\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=5\\
h=20
\end{cases}\implies V=\pi (5)^2(20)

Walking lights are placed around the perimeter of rectangular garden 30 feet be 16 feet and are placed 18 inches apart. How many
Masteriza [31]
Well we can find the perimeter by using the formula P=2L + 2W 
P=2(30) + 2(18)      P=60+36     P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed. 
96÷18=5.333333 
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
