Answer:

Step-by-step explanation:

Regular charge- $20                                      

Every hour of service cost- $40

Equation or slope intercept form-

C= 40h+20

Part 1-  20+40(8)=

40 multiplied by 8                320+20         = $340

Part 2-  20+40(10)=

40 multiplied by 10             400+20           = $420

Hi there!

Since we know that 36 is 1/10 of 360, all we need to do is divide the total area (85) by 10. This gives us 8.5pi ft^2.

Hope this helps!! :)

Which polygon has an interior angle sum of 1080
Snezhnost [94]
The sum of the interior angles in a regular polygon is given by the formula 180<span>(n – 2), where n is the number of sides in the polygon. An octagon has </span>eight<span> sides, so the sum of the angles of the octagon is </span>180<span>(8 – 2) = </span>180(6<span>) = 1080 degrees. In other word your answer would be an octagon.

Find the missing length. The triangles are similar.
asambeis [7]

Answer:

Missing length = 12

Step-by-step explanation:

Let x represent the missing length.

Since the triangles are similar, ∆KLM ~ ∆KRS, therefore, the ratio of their corresponding side lengths would be the same. This implies that:

KL/KR = KM/KS

KL = 65

KR = 65 - 52

KR = 13

KM = 60

KS = x

Plug in the values

65/13 = 60/x

Cross multiply

65*x = 60*13

65x = 780

Divide both sides by 65

65x/65 = 780/65

x = 12

What is the range of the function?
IgorLugansk [536]
The range is our Y-values and the domain is our x-values

Our Y's are 2, 2, 3, 4...doing both 2's are redundant, so we write it as {2, 3, 4}
