Answer:
29.3 minutes
Step-by-step explanation:
The average, also the mean, is all the numbers added together and then divided by the amount of numbers there, here, all the numbers added together are 20 + 30 + 40 + 38 + 25 + 22 + 39 + 22 + 26 + 31 = 293
There are a total of 10 numbers here, so 293/10 = 29.3

Answer: SU, TU, ST is the right answer
Step-by-step explanation: In a triangle
The largest side and the largest angle are opposite to each other
The shortest side and the shortest angle are opposite to each other.
So using the above axioms we can observe the triangle.
The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
The smallest angle is m∠T = 25° so the shortest side is SU
The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°
So the sides in order from least to greatest are: SU, TU, ST
There is a mid ocean ridge between South America and Africa causing the two continents to drift away from each other. South America and Africa have moved 250 cm away from each other in the last 100 years. What is their average speed?
Answer:
2.5 cm/year
Step-by-step explanation:
Just divide the total distance, 250 cm, by the years, 100, 250/100 = 2.5, the rate of the contintents drifting away is 2.5 cm per year, 2.5 cm/year

Find the value of x in the triangle shown below.
Answer:
102 degrees.
Step-by-step explanation:
Because the 3.3's are congruent (the same), this triangle is isosceles.
A property of isosceles means that the two angles are congruent.
39+39= 78
This means that the last angle must be 180-78.

Find the median of the following data set: "4 8 5 3 9 7 6"
Answer:
6, Arrange your numbers in numerical order, Count how many numbers you have, If you have an odd number, divide by 2 and round up to get the position of the median number, then If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.
i dont know lateral surface area lol
Answer:
72 pi
Step-by-step explanation:
Think of the lateral surface area as a label on a soup can. When you roll it out, then the circumference becomes the length and the height of the cylinder becomes the width or vise versa. So if 2(pi)(r) is the formula for the circumference, then that is 8. 8*9 is 72 and you multiply that by pi to get 72 pi

2.2 ≤ 2.25 true or false?
True,
2.2 is equal to 2.2 Imagine it like this.
22 < 225 correct right? Well look at this 22<22 is wrong it should be equal, so we added on a five to make it more greater!
Answer:
false
Step-by-step explanation:
≤ means greater than or equal to. 2.25 is greater than 2.2, there isn't a possibility that 2.2 is greater than 2.5 even if it was estimated 2.4 would be the greatest number, hence the use of ≤ is invalid.

Step-by-step explanation:
There is a rectangle and a triangle
Rectangle: 7*3 = 21

80% of a number is x.
What is 40% of that same number?
Answer:
Step-by-step explanation:
ntroduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
80% = 80/100 = 80 ÷ 100 = 0.8
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 80% of what number = 40?
80% of what number = 40 is equivalent to:
80% × ? = 40
80% × ? = 40
? =
40 ÷ 80% =
40 ÷ (80 ÷ 100) =
(100 × 40) ÷ 80 =
4,000 ÷ 80 =
50
