Find The Value Of X.2845x=[?]

Answers

Answer 1

Answer:

x=53

Step-by-step explanation:

One way to solve this problem is by using the Pythagorean Theorem.

This states that the square of one "leg" of the triangle plus the square of the other "leg" of the triangle would equal the square of the hypotenuse,  or the longest side of a triangle. Keep in mind that this only works for right triangles, where one angle  is exactly 90 degrees.

This formula can be written as: a^2 + b^2 =  c^2, where a and b are the legs and c is the hypotenuse.

So, for this problem, let a=28, and b=45.

This gives us: 28^2 + 45^2 = x^2

And we can simplify this to: 2809 = x^2

Taking the square root of both sides gives us the answer,  that x=53 units.

Hope this helps!

Answer:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

If amount of utility bill is normally distributed with a mean of $105 and a standard deviation of $20. What percentage of your bills would you expect to be between $85 and $125?

Answers

Answer:

68% of your bills between $85 and $125

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = $105

Standard deviation = $20

What percentage of your bills would you expect to be between $85 and $125?

85 = 105 - 20

125 = 105 + 20

Within one standard deviation of the mean, so by the Empirical Rule, 68% of your bills between $85 and $125

a train travels 16 miles in 20 minutes how many minutes would 12 miles be

Answers

Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

16 miles     =  12 miles

20 mins.        how many mins?

16    =   12       cross multiply       16? = 240   divide by 16     240 divided by 16 = 15 miles

20          ?                                                                                because 15 x 16 = 240

Answer:

It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

Write and solve an equation of ratios:

C) 1/3, 2, √7

Step-by-step explanation:

√7= 2.6

1/3= 0.3

2=2

1/3, 2, √7

C.

*if using a calculator*

1/3= .333

square root 7 equals about 2.646

therefore, we know .333 (1/3) is the smallest out of the numbers and 2.646 (sqr root 7) is the biggest.

*if you cannot use a calculator*

We know 1/3 is less than 1 because 3/3 would equal 1 and we only have 1/3.

We don’t know the square root of 7, however we know that it has to be between 2 and 3 because the square root of 4 is 2 and the square root of 9 is 3. 7 is between those two numbers, so therefore we know that the square root would have to be between 2 and 3.

Knowing that, we could figure out that since 1/3 is less than 1 it would be the smallest. Since the sqr root of 7 is between 2 and 3, it would be bigger than 2 and the biggest out of the 3.

Conclusion:

The order is 1/3, 2, sqr root 7
