2.5_3.5x=8_4x_6
_3.5x=0.5_4x
_7.5x =0.5
x=_7.5÷0.5
Answer:
.40km or 1/4 a mile
Step-by-step explanation:
Answer:
8.5
Step-by-step explanation:
The length of a segment can be found from its end coordinates by using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((8 -2)² +(4 -(-2))²) = √(6² +6²) = √72
d ≈ 8.485 ≈ 8.5
The length of MN is about 8.5 units.
Answer:
Step-by-step explanation:
Given
Required
How far did they row together
To do this, we simply add the distance they both covered.
This gives;
Take LCM
Simplify
<em>Hence, they both rowed 1/2 mile</em>
Answer:
165
Step-by-step explanation:
Here we have to use the ratio.
Both earth and Pluto are in similar shapes.
To find the number of sphere the size of Pluto does it take to have the same volume, we need to divide the earth's volume by Pluto's volume.
= Earth's volume/Pluto's volume
= 4/3 π (6371)^3 ÷ 4/3 π (1161)^3
Cancelling out 4/3 π both in the numerator and in the denominator, we get
= (6371)^3 ÷ (1161)^3
= 258596602811 ÷ 1564936281
= 165.24
Approximately 165 spheres the size of Pluto to cover the earth volume.
Thank you.
