Answer:
? = 85°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum of the angles around a point = 360° , so
interior angle on right = 360° - 250° = 110°
sum the interior angles and equate to 540°
110° + 115° + 120° + 110° + ? = 540° , that is
455° + ? = 540° ( subtract 455° from both sides )
? = 85°

11) Terry earns $30 per hour walking
dogs. Terry pays $150 each month to a
grooming service for the dogs. Which
equation represents Terry's profit, y, for
walking x dogs?
a) y = 30 + 150x
b) y = 30x + 150
c) y = 30 - 150x
d) y = 30x - 150
So
here
rate of pay=30$ per hourIf hours be x
Question asked to plot a equation to calculate profit so all the expenses or loss should be deducted,here the constant loss is of 150 so 150 should be subtracted
The equation in slope intercept form
y=mx+by=30x-150Answer:
d) y = 30x - 150
Step-by-step explanation:
Let x = number of hours worked
Let y = profit earned
Profit is the amount left after expenses are deducted.
Given:
Terry earns $30 per hour walking dogs⇒ y = 30x
Given:
Terry pays $150 each month to a grooming serviceThis is Terry's expenses, so we must deduct this amount from the amount he earns walking the dogs to calculate the final profit:
⇒ y = 30x - 150

Dennis is driving down the East Coast of the United States. He starts in Boston, MA, and drives through Hartford, CT, which is approximately 101 miles away from Boston. He continues on from Hartford to Baltimore, MA.
Write an equation for the length of Dennis' trip in miles in terms of the hours it takes him to drive from Hartford to Baltimore and the speed he drives in miles per hour while driving from Hartford to Baltimore. Describe all variables used and what each coefficient means
The equation representing the length of Dennis' trip in miles in terms of the time it takes to travel and the speed of Dennis is: d = s×t miles
How are time taken for travel, distance traveled, and the average speed are related?We have this below shown relation between them
[tex]\text{Average speed} = \dfrac{\text{Distance traveled}}{\text{Total time taken to travel that distance}}\\\\or\\\\\text{Total time taken to travel that distance}= \dfrac{\text{Distance traveled}}{\text{Average speed} }[/tex]
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Let we take:
Distance from Hartford to Baltimore = d milesTime it takes for Dennis to drive from Hartford to Baltimore = t hoursAverage speed of Dennis in the considered drive = s miles per hour.Then, we get:
[tex]s = \dfrac{d}{t}\\\\d = s \times t \: \rm miles[/tex]
Thus, the equation representing the length of Dennis' trip in miles in terms of the time it takes to travel and the speed of Dennis is: d = s×t miles

Cody is painting the front door of his house. The dimensions of the door are 80 inches by 36 inches by 2 inches. If he paints all of the surfaces how much area will he paint? Explain.
Answer:
To find out how much area he will paint, you will find the area of all 6 faces.
Each face is in the shape of a rectangle, so use A = lw as your formula.
Front/Back: 80 x 36 = 2880 square inches
2880 square inches x 2 = 5760 square inches
Right/Left Sides: 80 x 2 = 160 square inches
160 square inches x 2 = 320 square inches
Top/Bottom: 36 x 2 = 72 square inches
72 square inches x 2 = 144 square inches
5760 + 320 + 144 = 6224 square inches.
Cody will paint 6224 square inches.

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/s. when sharon jumps, megan throws a beach ball up to sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground. to the nearest hundredth of a second, how long after she jumps does the ball reach sharon? 0.65 seconds 0.92 seconds 1.08 seconds 1.15 seconds
It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.
What is the equation of motion?It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.
We have:
The height of the Sharon from the diving board = 18 feet
The initial upward velocity of the Sharon = 4 ft/s
The height of the Megan from the ground = 5 feet
The initial upward velocity of the beach ball = 16 ft/s
We know the equation of motion is given by:
[tex]\rm h(t) = x + ut+\frac{1}{2} gt^2[/tex]
Put x = 18 feet and u = 4 ft/s in the above equation, we get:
[tex]\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2[/tex] ....(1) [g = 9.8 m/s²]
Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:
[tex]\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2[/tex] ....(2)
Equate the equation (1) and equation (2), we get
[tex]\rm 18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\[/tex]
18 + 4t = 5 + 16t
12t = 13
t = 1.08 seconds
Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units? (x – 9)2 (y 4)2 = 25 (x 4)2 (y – 9)2 = 25 (x – 9)2 (y 4)2 = 100 (x 4)2 (y – 9)2 = 100
The circle can be illustrated by its equation, and the equation that represents the circle is (x + 4)² + (y - 9)² = 5²
How to determine the circle equation?The center of the circle is given as:
Center, (a,b) = (-4,9)
The diameter is given as:
d = 10
Calculate the radius (r)
r = 10/2 = 5
The circle equation is then calculated using:
(x - a)² + (y - b)² = r²
So, we have:
(x + 4)² + (y - 9)² = 5²
Hence, the equation that represents the circle is (x + 4)² + (y - 9)² = 5²
