Its Letter B -0.5

negative because its slope is negative (from left to right it's going downward)

so there are 2 negavite numbers in the choices, -0.5 and -0.95.

The nearer the value to 1 the less scatter it is. The farther the value to 1 (means nearer to 0) the more scatter it is. Because the plot in the picture is mostly scattered the value should be nearer to 0. It is negative 0.5.

sdas [7]

It takes him 17 minutes to make each shoe.

How to Solve:

take away the 30 min lunch break from the time becomes 11:45 to 4:00
calculate the distance from 11:45 to 4:00 which is 4 hours and 15 minutes to complete each shoe.
Convert the hours into 60 minutes each so 60*4= 240 now add the extra minutes 240+15= 255 minutes
Now divide that bye 15 shoes 255/15= 17 minutes
So it takes 17 minutes to make each shoe. :)

A cylindrical soup can has a radius of 1.8 in. and is 6.7 in. tall. Find the volume of the can.

avanturin [10]

<h3>Initial considerations</h3>

radius = 1.8 in
tall = 6.7 in
Volume?

<h3>Resolution</h3>

Volume = base area x tall

base area = π x (1.8in)²

base area = 10.179 in²

Volume = 10.179 in² x 6.7 in

Volume = 68.198 in³

<h3 /><h3>Answer</h3>

the volume is 68.198 in³

You gave the server at a restaurant a 22% tip and ended up paying $41.48. What was the price of your meal before you applied the

const2013 [10]

Answer: The price of meal before the tip = $34.

Step-by-step explanation:

Given : The percentage of tip = 22% = 0.22 ( we divide a percentage by 100 to convert it into decimal)

Total amount paid ( including tip) = $41.48

Formula for Total bill = Price of meal + Tip amount , where Tip amount= 22% of Price of meal.

Let x be the price of meal, then

Total bill =x + 0.22 x (x )

⇒ $41.48= x(1+0.22) [ By distributive property]

⇒ $41.48 = x (1.22)

⇒ x= ($41.48) ÷ 1.22

⇒ x= 34

Hence, the price of your meal before you applied the tip = $34.

Answer:

x = 10

Step-by-step explanation:

The total measures of a circle must add up to 360°. In the diagram given there are two angles that are not given, however, both of these should be equal to each other. That means that the sum of the other two angles ('5x - 5' and 93°) must be equal to the other angle of the same measure (138°):

5x - 5 + 93 = 138

Combine like terms: 5x + 88 = 138

Subtract 88 from both sides: 5x + 88 - 88 = 138 - 88 or 5x = 50

Divide by 5: 5x/5 = 50/5 or x = 10
