Answer:
Step-by-step explanation:
The answer is 15
Answer: See explanation
Step-by-step explanation:
1. Step 1: Add up all the numbers.
12 + 15 + 10 + 15 + 11 + 12 + 15 = 90
Step 2: Count how many numbers there are.
There are 7 numbers
Step 3: Divide the sum of the numbers by amount of numbers.
90 ÷ 7 = 12.85
12.85 ≈ 12.9
Mean = 12.9 in tenth place or 13 in whole place
2. The mode is the number that appears the most
15 appears 3 times.
3. 38 / +38
4. 1 week = 7 days
7 × 2 = 14
9 weeks = 9 × 7 = 63
63 × 3 = 189
189 + 14 = 203
203 miles in all
5. Area of 1st rectangle: b × h
4 × 14 = 56
Area of 2nd rectangle: b × h
4 × 14 = 56
56 + 56 = 112
Area of polygon = 112
Hope this helps!
Answer:
A square of side length 40 m will give the maximum area of the play area
Step-by-step explanation:
Mathematically, it has been established that a square gives the maximum area of a quadrilateral
Hence, for us to have a maximum area of the given perimeter, we have to divide the perimeter by 4 to get the side length of the square
From what we have, we know that the perimeter of the fencing is 160 m
To get the side length, we divide the perimeter by 4
Side length of the shape would be 160/4 = 40 m
First we clear y from the given equation
x + 10y = 260
10y = 260-x
y = (260-x) / (10)
Then, we evaluate the function within the domain of it
x = 0
y = (260- (0)) / (10)
y = (260) / (10)
y = 26
x = 10
y = (260- (10)) / (10)
y = (250) / (10)
y = 25
That is, you travel 1 mile in 10 minutes.
Therefore, traveling 26 miles will take:
(26) * (10) = 260 min
answer
it takes for the runner to reach the school 260min.
