Answer:
Step-by-step explanation:
We need to create an equation to represent how many air fresheners the teacher can buy.
Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.
x = number of air fresheners
($10 + $3) / $3.50 = x can be written as $13/$3.50 = x
We add $10 and $3 because that gives us the total amount she has to spend.
We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.
In this case.
$13/$3.50 = x
3.71 = x BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
C = 2pi*r
If we rearrange the terms to make r the subject,
We get r = C/2*pi
Hope it helps :)
The perimeter would be 228 inches
Hope this helped =)
Answer:
14.065
Step-by-step explanation:
First you wanna transfer it from kilometers to miles.
if 1 mile is = to 1.6 kilometers that is the same as saying
1/1.6, but because we are using 90 we plug it in and it becomes: 90/1.6 which gives you 56.25.
now we know we are going 56.25 miles per hour and because we are traveling 4 hours divide the miles per hour by 4 and you get 14.065.
