80% of a number is x.
What is 40% of that same number?

Answers

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

X/2 =0.5x

40% is half of 80%. So the answer should be half of x.

Find the value of x in the triangle shown below.

Answers

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.

The answer is almost certain to be 180

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.

i dont know lateral surface area lol

Answers

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

Average winter temperatures in 45 states were recorded and divided by geographic region. Choose True or False for each statement below

Answers

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

2.2 ≤ 2.25 true or false?

Answers

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.
