Good Afternoon,

Question #1. That answer is exactly D.

Question #2. That is going to be A, because $42.50 x 12 = $510

& Question #3. is C, because 15 x 4 = 60

Brainliest Please

Find the median of the data.

kipiarov [429]

Answer:

92.5

Step-by-step explanation:

The data given:

93, 81, 94, 71, 89, 92, 94, 99

Put the data in the ascending order:

71, 81, 89, 92, 93, 94, 94, 99

Since the data size is even, the median is the average of middle two:

median = (92 + 93)/2 = 92.5

Write the slope-intercept form of an equation that passes

Hunter-Best [27]

Answer:

$y = \frac{4}{3}x-5$

Step-by-step explanation:

As the line is perpendicular to $y=-\frac{3}{4} x + 2$ , we know that the slope of the line is $\frac{4}{3}$ . As it passes through $(3, - 1)$ , we know that it should be $y = \frac{4}{3}x-5$ .

Identify the center and the radius of each. x^+y^+26x-22y+281=0

inessss [21]

Answer:

Center (-13,11) , radius 3

Step-by-step explanation:

The given circle has equation

$x^2+y^2+26x-22y+281=0$

We compare this to the general equation.

$x^2+y^2+2ax+2by+c=0$

where (-a,-b) is the center.

This implies that;

2a=26

$\Rightarrow a=13$

2b=-22

b=-11

The center is therefore (-13,11)

The radius is given by

$r=\sqrt{a^2+b^2-c}$

$r=\sqrt{13^2+(-11)^2-281}$

$r=\sqrt{9}$

The radius is 3

FIND THE LENGTH AND WIDTH OF THE RECTANGLE

insens350 [35]

W = width
3w + 7 = length

Equation: 3w + 7 + w = 75
Combine like terms: 4w + 7 = 75
Subtract 7 to the other side: 4w = 68
Divide both sides by 4: w = 17

Width = 17
Length = 3(17) + 7, so 58
