Step-by-step explanation:
There are no solutions to 2x-5y=9 but if you are solving it by y=mx+b form than your answer would look like this: y=2/5x-9/5
Answer:
1 pi: 3pi
Step-by-step explanation:
Step 1: Formula of surface area and volume of sphere
Surface area of sphere = 4 x pi x r^2
Volume of sphere = <u>4</u> x pi x r^3
3
Step 2: Apply values in the formula
r = radius
radius = diameter/2
r=18/2 = 9
S.A = 4 x pi x 9^2
S.A = 324pi
Volume = <u>4</u> x pi x 9^3
3
Volume = 972pi
Step 3 : Show in ratio
Surface area : Volume
324pi : 972pi
= 1 pi: 3pi
Answer:

Step-by-step explanation:
we know that
1 mile=63,360 inches
step 1
Find the circumference of the wheels

we have
-----> the radius is half the diameter
substitute


assume


Remember that
The circumference of the wheels represent one revolution
Convert 59 miles per hour to inches per minute

using proportion find the number of revolutions

therefore
substitute
