Answer:

1, 5, 15

Step-by-step explanation:

First, I knew 5 was one of them because, 5 was the median and there were only three numbers. Next you have to find out the first and last number. Then, I looked at the mean. To get the mean, you have to add all of the numbers up and divide that by how many numbers there are. Since the mean is 7 and there are 3 numbers, I knew that the sum of all three numbers was 21 because, 21 divided by 3 is 7. Then I saw that the range of all the numbers was 14. The range is the difference between the largest and smallest number so I knew that the largest number subtracted by the smallest number had to be 14. Then, I saw that 15-1=14, and 1+5+15=21. So the three integers are, 1, 5 and 15.

A parking lot has 916 parking spaces that are shaped like parallelograms. The base of each space is 10 feet, and the height of e

dmitriy555 [2]

The area of a parallelogram is $A=bh$

$A=10(18.5) \\ A=185$

I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916

$185(916) = 169,460 ft^{2}$

So the answer is (D)

find the slope of the lines that pass through each pair of points. (-1,4) and (5,1); (-3,4) and (0, 10), m1= and m2=

Amiraneli [1.4K]

For these equations, we are going to use the slope formula, as defined below ( $m$ is slope and $(x_1, y_1)$ and $(x_2, y_2)$ are coordinate points):

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

We can simply "plug in" the coordinates we are given:

$m_1 = \dfrac{1 - 4}{5 - (-1)} = \dfrac{1-4}{5+1} = - \dfrac{3}{6} = - \dfrac{1}{2}$

$m_2 = \dfrac{10 - 4}{0 - (-3)} = \dfrac{10-4}{3} = \dfrac{6}{3} = 2$

Our answers are:

$\boxed{m_1 = - \dfrac{1}{2}}$

$\boxed{m_2 = 2}$

Write 0.22222222 as a fraction

Maslowich

Answer:

22222222/100000000

Step-by-step explanation:

To write 0.22222222 as a fraction you have to write 0.22222222 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number. 0.22222222 = 0.22222222/1 = 2.2222222/10 = 22.222222/100 = 222.22222/1000 = 2222.2222/10000 = 22222.222/100000 = 222222.22/1000000 = 2222222.2/10000000 = 22222222/100000000.
