Answer:
The value is 50.6cm
Step-by-step explanation:
In order to find this , set up a proportion. Use the smaller part of the triangle on top, and the corresponding part of the larger on bottom.
32.2/46.2 = x/72.6
Now cross multiply to solve
72.6*32.2 = 46.2*x
2337.72 = 46.2x
50.6 = x
V=4/3 π •r^3 multiply both sides with 3
3•36π=4π • r^3
108 π=4 π • r^3
r^3 =108 π/4 π
r=3 inch
First you will have to use the equation length*width*height. The just plug in 4 for the height, then since the length is 4 times longer plug in 4x, and the width would just be x. SO your equation would be 4*4x*x=6400 ft^3. Then foil it out to get 16x^2=6400, then square root 6400 which will give you80, then divide by 16 so x=5 feet^3. That is your width but you length is 4 times that amount. So for length just do 4(5)=20 feet^3
I hope this helps
3x-y=13
step 1: add y to both sides
3x-y+Y=13+Y
3x=y+13
step 2: divide both sides by 3
3x/ 3 = y+13/3
x=1/3y+ 13/3
answer: x=1/3y+13/3
Speed is the rate of change of distance.
the speed of the truck for the 100 miles within 2 hours is
speed = 100 miles travelled / 2 hours taken
speed = 50 miles/hour
assuming that the driver drives at 50 miles/hr
the time taken to drive 50 miles is - 1 hour
therefore to drive 300 miles - it takes - 300 miles / 50 miles/hr
the time taken is - 6 hours
it takes 6 hours to drive for 300 miles
