Answer:

17/23

Step-by-step explanation:

To find the slope of a line given 2 points, we use the formula

m = (y2-y1)/ (x2-x1)

= (66-15)/(90-21)

= 51/69

Divide the top and bottom by 3 to simplify the fraction

= 17/23

Answer: 0.74

Step-by-step explanation:

Slope is calculated as change in ydivided by change in x

= y2 - y1/x2 - x1

Step 1: Locate the coordinate points

From the question,

y2 = 66, y1= 15

x2 =90, x1 =21

Step 2:Then slot in the values into the formula

Slope (m) = 66-15/90-21

m = 51/69

m = 0.739

m is approximately 0.74

I hope this helps, please mark as brainliest answer.

ArbitrLikvidat [17]

Answer:

-10

Step-by-step explanation:

The constant is the part of the algebraic function or expression that does not change. In this case, as x changes, the constant -10 does not. Thus, -10 is the constant.

Find the area of the rug. DO NOT ROUND.<br><br> what is the area?

Mademuasel [1]

Answer:

$\frac{198}{7} \ \text{feet}^{2}$

<h3>Step-by-step explanation:</h3>

<u>Given:</u>

Diameter of rug = 6 feet

To find the area of the rug, we need to use the formula "πr² or π(D/2)²"

<u>Where:</u>

r = radius
d = diameter

Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

⇒ $\pi (\frac{D}{2} )^{2}$

⇒ $\pi (\frac{6}{2} )^{2}$

⇒ $\pi (3 )^{2}$

⇒ $\pi (3 )(3)$

⇒ $9\pi$

Substituting "22/7" as π:

⇒ $9(\frac{22}{7} )$

⇒ $(\frac{198}{7} )$

When finding the area of ANY shape, do not forget to include the units.

⇒ $\frac{198}{7} \ \text{feet}^{2}$
