The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and m is the y intercept.

Let y represent the total cost of hiring for x hours. Hence:

  • Using the points (0, 125) and (15, 950)

Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{950-125}{15-0} =55

The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour

A park has a large circle painted in the middle of the playground area. The circle is divided into 4 equal sections, and each se
oee [108]
First you need to find the area of the whole circle.\pi  r^{2}
The radius is given as 10, so just insert 10 into the equation of the area of a circle equation. 
Area =  \pi  10^{2}    Area =  100 \pi
Putting \pi after the 100 because that is what is commonly done. 

Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections. 

Since the area of the whole circle is 100 \pi then we just divide that by 4, 
leaving us with 25\pi and that is our final answer

Please help me due today i really need ur help :(

Answer:

1) B. $12

2) B. Rich burns 1 more calorie per minute than Katie

3) C. Jeffery walks 5 meters per minute slower than Fumi.

Step-by-step explanation:

1)  earnings / hours = salary

salary = 24/2 = 60/5 = 96/8 = 12

salary = $12

2) The question describes Rich's graph to have the function of "y=8x." The graph shown that represents Katie's number of burned calories has the function of "y=7x." From that we can conclude Rich burns one more calorie per minute. See attached file for graph.

3) The question describes Fumi's graph to have the function of "y=85x." In order to find the function of Jeffrey's graph, we must use the two points provided from the graph. The point (10, 800) tells us that the point (1,80) would also fall on the line. From that, we can determine Jeffery's function to be "y=80x." 80 is 5 less than 85, so Fumi walks 5 meters per minute faster than Jeffery.

Which relationship describes angles 1 and 2?
tamaranim1 [39]
Angles 1 and 2 are adjacent, we know this because they are side by side. Meaning they are adjacent.

Angles 1 and 2 are also complementary because they add up to 90°
