Answer:
<u>Volume=2.2*10^10 km^3
</u>
Step-by-step explanation:
Given
Diameter of moon=d=3476 km
The formula for the volume of sphere is:
V=4/3 πr^3
As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first
So,
radius=r=d/2
=3476/2
=1738 km
Now putting the value of r and pi in the formula:
V=4/3*3.14*(1738)^3
=12.56/3* 5249879272
= 21979494552.106
Rounded off to two significant digits:
<u>Volume=2.2*10^10 km^3
</u>
The cost of the mixture is $69 *$1 = $69. If all 69 pounds were peanuts, the cost would be 69*$0.99 = $68.31, which is $0.69 less. Each pound of walnuts used instead of peanuts adds $0.03 to the cost of the mixture, so there were $0.69/$0.03 = 23 pounds of walnuts.

<span>Let w represent the number of pounds of walnuts in the mixture. Then 69-w is the number of pounds of peanuts. The cost of the mixture will be </span>
<span>1.02w + 0.99(69-w) = 1.00*69 dollars </span>
<span>0.03w + 68.31 = 69.00 </span>
<span>w = (69.00 - 68.31)/0.03 = 0.69/0.03 = 23</span>
Answer:
get all the varibles on one side
Step-by-step explanation:
mark me as brainliest plz thx
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
