Answer:
C
Step-by-step explanation:
Diameter of a semi circular garden = 18 feet
Radius of the garden :
Thus, the radius of the semi circular fence = 9 feet
We know that :
Which means, the circumference of Mary's semi circular garden :
(pi value = 3.14)
Thus, the circumference of fence needed for the semi circular garden = 28.26 feet
28.26 can be rounded off to 28.30 and 28.30 is the same as 28.3
Thus, Mary's reasoning is correct.
Therefore, Mary's reasoning is correct which means she needs 28.3 feet of fence to surround her garden.
Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
<h3><u>How to solve this problem?</u></h3>
The way I would solve this problem is by first finding the unit rate, or the rate that the jet plane travels in one minute. Then I would multiply the rate by the number of minutes I want to know how far the jet plane flies; in this case it would be multiplied by 18 minutes.
<h3><u>Finding the unit rate.</u></h3>
Let's start by finding the unit rate. To find the unit rate we would divide the ratio, 450 miles:60 minutes (one hour) by 60 minutes to make the 60 minutes become one minute and 450 miles become 7.5 miles.
450 miles:60 minutes ÷ 60/60
7.5 miles:1 minute
<h3><u>Solving the question.</u></h3>
The unit rate is 7.5 miles per minute. Since we know the jet plane flies 7.5 miles every one minute, we can multiply this amount by 18 minutes to find how many miles the place can fly in 18 minutes.
7.5 miles * 18 minutes = 135 miles
The answer to your question is the jet plane travels 135 miles in 18 minutes.
Answer:
Y intercept is 275. X intercept is 125.
Step-by-step explanation:
The y intercept is where the line meets the y axis. The x intercept is where the line meets the x axis. You just have to look at those.
