Answer: 150
Step-by-step explanation: so when you want a whole amount of something you want to the 100% of it because 100% is the whole thing right? Well right now you only have 20% so how much do you need to multiply that by to get 100%?? Well that answer is 5. Okay so now since $30 is 20% but we wanna get it to 100% multiply it by 5 so 30x5 which is 150
Use 0 as the y value then solve for x. answer: 3
Divide 2 from both sides
t < 5/2
Hope this helps!
Answer:
Step-by-step explanation:
Remember that
Area of Circle = 
They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =
Divide both sides by 
.
144 = 
Now we want to solve for r (r = radius).
You need to square root each side
So now we know the radius, 
metres
Also remember that
Diameter = 
So,
Diameter = 2 times 12 = 24 metres
Thank you for posting your question here. Please see below answers for the problem above:
a. to find the circumference of the tire you need to multiply 3.14 by 2.5:
= 3.14 x 2.5
= 7.85 to round of it will be 8
b. to get the number of times the tire have to rotate to travel 1 mile:
1 mile = 5,280 ft
1 rotation is 7.85
5,280/7.85 = 672.611465
