The function is illustrated below based on the information.

<h3>How to describe the function?</h3>

When x <= 8000

The cost remains constant at 0.35 when x increases from 0 to 8000. The slope of the cost function over this part is 0

When 8000 < x <= 20000

The cost remains constant at 0.75 when x increases from 8000 to 20000 and the slope of the cost function over this part is 0.

There are 127 lbs of fruits in the store: apples, oranges, and peaches. There are four times as many apples as there are peaches
Pepsi [2]
Let
x------> amount of pounds of apples
y------> amount of pounds of oranges
z-----> amount of pounds of peaches

we know that
x+y+z=127------> equation 1
x=4z-----> equation 2
y=7+z----> equation 3

substitute  equation 2 and equation 3 in equation 1
x+y+z=127----> (4z)+(7+z)+z=127---> 6z=127-7---> 6z=120----> z=20 lb
x=4z---> x=4*20----> x=80 lb
y=7+z----> y=7+20---> y=27 lb

 amount of pounds of apples----> 80 lb
amount of pounds of oranges----> 27 lb
amount of pounds of peaches---> 20 lb

riadik2000 [5.3K]

<u>Answer </u><u>:</u>

In the given quadrilateral ABCD ,

  • Angle BCA = 18°
  • Angle ACD = 62°

Angle BCA = Angle CAD ( alternate interior angle )

Now in triangle CAD ,

We have two angles so by using angle sum property we can find the required third one ,

  • Angle CAD + Angle ACD + Angle ADC = 180°
  • 18 + 62 + Angle ADC = 180
  • 80 + Angle ADC = 180
  • Angle ADC = 180 - 80
  • Angle ADC = 100

Step-by-step explanation:

Let x and y be the first number and second number respectively.

According to the question, we can find 2 equations:

2x + 5y = -5

3x + 10y = -5

On solving,

x = -5

y = 1

1. Eight people work in an office. They are paid hourly rates of 12£,15£,15£,14£,14£,13£,14£,13£
bearhunter [10]

Answer:

mean=110/8 =13.75 pounds;  median=14 pounds; mode=14 pounds; average=13.75 pounds

Step-by-step explanation:

mean=add all the numbers together to get total then divide that total by the number of amounts present 12, 15, 15, 14, 14, 13, 14, 13 =110, then 110/8=13.75 pounds

mode=arrange amounts in order (smallest to largest), then determine which amount appears more than the other amounts 12, 13, 13, 14, 14, 14, 15, 15 =14 appears the most

median=organize numbers from smallest to greatest, count how many there are, then determine which number appears in the middle of all of them 12, 13, 13, 14, 14, 14, 15, 15 = there are 8 numbers present but 14 is in the middle; answer =14

average= take total of mean, then divide it by the number of amounts that appear 110/8 =13.75
