2 A marathon race is 42 195 m in length. The world record in 2016 was
2 hours, 2 minutes and 57 seconds held by Dennis Kimetto of Kenya.
a How many seconds in total did Kimetto take to complete the race?
b Calculate his average speed in m/s for the race, giving your answer to
2 decimal places.
c What average speed would the runner need to maintain to complete
the marathon in under two hours?
Answer:
A. 7377 s
B. 5.72 m/s
C. 5.86 m/s
Step-by-step explanation:
A. Determination of the time in second.
Time (t) = 2 hours, 2 minutes and 57 seconds
We'll begin by converting 2 hours to seconds. This can be obtained as follow:
1 hour = 3600 s
Therefore,
2 hour = 2 hours × 3600 s / 1 hour
2 hours = 7200 s
Next, we shall convert 2 mins to seconds. This can be obtained as follow:
1 min = 60 s
Therefore,
2 mins = 2 mins × 60 s / 1 min
2 mins = 120 s
Finally, we shall determine the total time in second. This can be obtained as follow:
2 hours, 2 minutes and 57 seconds = 7200 s + 120 s + 57 s
= 7377 s
Therefore, the total time in second is 7377 s
B. Determination of the average speed.
Total distance = 42195 m
Total time = 7377 s
Average speed =?
Average speed = Total distance / total time
Average speed = 42195 / 7377
Average speed = 5.72 m/s
Therefore, the average speed is 5.72 m/s
C. Determination of the average speed.
We'll begin by converting 2 hours to seconds. This can be obtained as follow:
1 hour = 3600 s
Therefore,
2 hour = 2 hours × 3600 s / 1 hour
2 hours = 7200 s
Finally, we shall determine the average speed. This can be obtained as follow:
Total distance = 42195 m
Total time = 7200 s
Average speed =?
Average speed = Total distance / total time
Average speed = 42195 / 7200
Average speed = 5.86 m/s
Therefore, the average speed is 5.86 m/s.
Simplify 12(A - B).
I don’t understand?
Answer:
12A-12B
Step-by-step explanation:
In the parentheses, it is A-B. Using the distributive property you break up the parentheses then you have 12xA - 12xB. This is known as the "Santa Hat". The lines mean that you do each function to each constant, variable, or term.

what is the length of the right triangle below in inches?
Answer:
6in
Step-by-step explanation:
Using the pythagerous thereom,
10^2 = 8^2 + b^2
b^2 = 10^2-8^2
b^2 = 100-64
b^2 = 36
b = 6
Feel free to mark this as brainliest :D
Answer:
6
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
?^2 + 8^2 = 10^2
?^2 +64 = 100
?^2 = 100-64
?^2 = 36
Take the square root of each side
? = sqrt(36)
?= 6

U
B. y + 3 = -4(x-6)
O C. y-6 = -4(x + 3)
D. y=-4x-6
Answer:
D. y = -4x - 6
Step-by-step explanation:
→ Work out gradient of line
[tex]\frac{2-6}{-2--3} =\frac{-4}{1} =-4[/tex]
→ Write into y = mx + c format
y = -4x + c
→ Substitute ( -2 , 2 ) into the equation to find c
2 = 8 + c
→ Minus 8 from both sides
-6 = c
→ Write full equation y = -4x - 6

On a map, 1 inch equals miles. Two houses are inches apart on the map. What is the actual distance between the houses? Use pencil and paper. Show how you can represent the scale with two different ratios.
Answer:
The actual distance between the houses is 18.9 miles.
Step-by-step explanation:
The exact question is as follows :
Given - On a map, 1 inch equals 5.4 miles. Two houses are 3.5 inches apart on the map.
To find - What is the actual distance between the houses?
Solution -
Given that,
1 inch = 5.4 miles
⇒3.5 inches = 3.5 × 5.4 miles
= 18.9 miles
∴ we get
The actual distance between the houses is 18.9 miles.

A. 10
B. 8
C. –1
D. –10
Answer:
D. –10
Step-by-step explanation:
Given equation:
y = 3x – 1
what is the value of y when x equals –3?
Substitute x = -3 into the equation to find y
y = 3x – 1
= 3(-3) - 1
= -9 - 1
= -10
y = -10
The correct answer is D. –10

Use pythagorean theorem to find perimeter
Answer:
36
Step-by-step explanation:
Counting the squares: base = 12, height = 9.
We will use pythagorean theorem to find the third side.
Let it be x.
So,
[tex]x^2 = 12^2 + 9^2\\x^2 = 144 + 8 1 = 225\\x = 15[/tex]
Perimeter of triangle = sum lengths of all sides
= 12 + 9 + 15
= 36 units

30 students in a class went on a trip to the other side of the city. There were 4 vans for the
students to take. 6 students walked. How many students could fit in each van?
Answer:
6

Round 0.10947 to the nearest hundredths place.
Answer:
0.11
Step-by-step explanation:
The number is 0.10947. So, to round to the nearest hundredth you’d take the number behind the number in the hundreds place, 0, and if it’s 5 or higher that number would go up. Since the number behind 0 is 9 which is higher than 5 that 0 would become a 1. Giving you 0.11!

Given that n(A) = 12, n(B) = 7
and n(AUB) = 10
Find n(AnB)
Pls show working
Answer:
n(A) + n(B) - n(AnB) = n(AUB)
12 + 7 - n(AnB) = 10
19 - n(AnB) = 10
19 - 10 = n(AnB)
n(AnB) = 9
Step-by-step explanation:
Step-by-step explanation:
n(A)=12
n(B)=7
n(AUB)=10
n(AnB)=?
let,n(AnB) be x
We know that,
or, n(AUB) = n(A)+n(B)-n(AUB)
or, 10 =12+7+x
or, 10 =19+x
or, 10-19=x
or,9=x
so, the value of x is 9
then (AnB)=9
