Answer: The tree is 27 feet tall.
Step-by-step explanation:
Here's what we know:
6/10 = x/45 (a 6 foot object creating a 10 shadow is equivalent to something else making a 45 shadow)
We need to isolate x. Multiply both sides by 45:
6*45/10 = x
We can factor out a 2:
3*45/5 = x
We can also factor out a 5:
3*9/1 = x
27 = x
The tree is 27 feet tall.
Answer:
Step-by-step explanation: To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor.
Set up a proportion where number of times is on top and miles is on bottom:
6/1 = x/(5/6)
Cross-multiply:
6*(5/6) = 1*x
5 = x
She must run 5 times around her neighborhood.
