When 80% of a is added to the number, the result is 252. What is the number

Answers

Answer 1
Answer: Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.

1.8x = 252

x = 140
Answer 2
Answer:

Final answer:

To find the original number, 'a', in this algebra problem, we set up and simplify the equation a + 0.80a = 252 to get a = 252 ÷ 1.80. Solving this equation will give us the value of 'a'.

Explanation:

The subject here is mathematics, specifically algebra. The problem can be solved by setting up an equation that represents the described scenario. Let 'a' be the unknown number. The problem states that adding 80% of 'a' to the number gives us 252. This can be expressed as the equation: a + 0.80a = 252.

By simplifying this equation, we get 1.80a = 252. To find the value of 'a', we divide both sides of the equation by 1.80. Doing that, we get a = 252 ÷ 1.80. Hence solving this will give us the original number

The interior angles in a regular polygon are 140 degrees. How many sides has the polygon? it could be something to do with s=(n-2) x 180

Answers

Yes, it certainly could !  When you first noticed that formula in a book, or when it was given to you in class, did you also notice or learn what it means ?

It means
"The sum of all the interior angles in a polygon" = (number of sides - 2) x 180.

Triangle ........ 3 sides ... (3 - 2) = 1 x 180 = 180° degrees ... 60° each if regular
Quadrilateral . 4 sides ... (4 - 2) = 2 x 180 = 360° degrees ... 90° each if regular
Pentagon ...... 5 sides ... (5 - 2) = 3 x 180 = 540° degrees ... 108° each if regular
Hexagon ....... 6 sides ... (6 - 2) = 4 x 180 = 720° degrees ... 120° each if regular
Sevenagon ... 7 sides ... (7 - 2) = 5 x 180 = 900° degrees ... 128 and 4/7 each if regular
Octagon ........ 8 sides ... (8 - 2) = 6 x 180 = 1080° degrees ... 135° each if regular
Nonagon ....... 9 sides ... (9 - 2) = 7 x 180 = 1260° degrees ... 140° each if regular

Solve 4x-2=2x-10 help

Answers

4x-2x=-10+2
2x=-8
x=-8/2
x=-4
4x - 2 = 2x - 10
4x - 2 - 2x = (2x - 10) - 2x
2x - 2 = -10 
(2x - 2) + 2 = -10 + 2
2x = -8
2x / 2 = -8 / 2
x = -4

Student take an average of 45 minutes and standard deviation of 8 minutes to complete a certain statistics test. If a student is selected at random, what is the probability that the student takes more than 56 minutes to compete the test?

Answers

A standard normal table can be used to estimate what part of a normal distribution will fall within a certain range, given the number of standard deviations (or Z-Score) from the mean. 56 minutes is 11 minutes from 45, and the standard deviation is 8, so the Z-Score is 11/8 = 1.375. The lookup table gives 8.5% complementary probability (greater than the given number of standard deviations) for 1.37 and 8.4% for 1.38. Checking a graph, the part of the curve above 1.375 standard deviations should be somewhere between 5 and 10%, so this seems reasonable.
