The median is 28; 16,24,x,48
Nookie1986 [14]
x = 32 

To find the media, you take the middle number. If there is no discrete middle number, take the sum of the two closest to the middle and divide by 2. 

(24 + x)/2 = 28

Multiply by 2 on both sides to get:

24 + x = 56

Subtract 24 from both sides to isolate the variable:

x = 56 - 24
x = 32

Mr. Alvarado bought a total of 20 pounds of grass seed at the nursery for $168. He paid $9 per pound for Kentucky blue grass and
Nuetrik [128]

Answer:

K+T=20

$9K + $6T = $168

K is the Kentucky blue grass in pounds

T is the Tall fescue in pounds

Step-by-step explanation:

You can start with the first equation. We don't know the exact amounts of each but we know that there was a total of 20 pounds, and there were 2 types of grass seeds, so we can get that the amount of pounds of Kentucky blue grass(K) and the pounds of Tal Fescue(T) has a sum of 20.

K + T = 20

For the second equation we know that there is a sum of $168 so we'll start with that. Then, we know he paid $9 per pound of K so $9* the value of K is the amount paid for Kentucky blue grass total. This can be represented as 9K. We do the same for T, 6T. Since the sum of the cost of $9T and $6K must be $168 we can write this as:

$9K + $6T = $168

PLEASE HELP I WILL MARK YOU BRAINLIEST THERE IS A PICTURE AT THE BOTTOM.
Kitty [74]

Answer:

72 sq. inches

Step-by-step explanation:

We are trying to find the area of the shaded part, and so we start with finding the area of the entire half that is marked (the area with measurements). The length is 8 in, as seen on the bottom, and the height is 12 in, as seen on the side. 8 * 12 = 96, so the entire portion from the shaded part to the very right is 96 sq. inches. Now we have to take out the white triangle part to find the area of the shaded part. Area of a triangle = 1/2*base * height, so we multiply 1/2 * 12 * 4, which gets us 24. Now that we know the area of the triangle, we subtract it from the previous area we got, which was the area of the shaded part plus the triangle (96). 96 - 24 = 72, so the area of the shaded portion is 72 sq. inches. Hope this helps!

If the quadratic equation x2+18x+74=0 is rewritten in the form (x−p)2=q, what is the value of q?
PilotLPTM [1.2K]

Answer:

<em>C) 7</em>

Step-by-step explanation:

<u>Quadratic equation</u>

The quadratic equation can be written in several ways, one of the most-used is

ax^2+bx+c=0

To rewrite the equation in the form

(x-p)^2=q

we can complete squares and rearrange the terms as follows. The provided equation is

x^2+18x+74=0

The second term can be seen as

2(x)(9)

And the first two terms can be visualized as the square of a binomial

x^2+2(x)(9)+81-81+74=0

We have added and subtracted 81 to complete the square and not modify the equation. The new form of the equation is

(x+9)^2-7=0

Rearranging

(x+9)^2=7

Comparing with the general form written above, we find that

\boxed{q=7}
