Kylie is in the business of manufacturing phones. She must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. The daily fixed costs are $600 and and the total cost of producing 4 phones in a day would be $1600. Write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.
Answer:
C= 400P+ 600Step-by-step explanation:
In this problem, we are to model the equation for the total cost of producing a phone
Given that the fixed cost is $600
Also, the total cost of producing 4 phones in a day is $1600
hence the cost of producing 1 phone would be 1600/4= $400
the equation for producing p phones would be
C= 400P+ 600
This equation is the same as the equation of a straight line Y=mx+c
with C=y
400= m= gradient
P=x, the dependent variable
600= c the constant term.
Answer:
c=250+600

Answer:
1/36
Step-by-step explanation:
To get a sum of 2, both dice must roll a 1.
The probability of a 1 on the first die is 1/6.
The probability of a 1 on the second die is 1/6.
Therefore, the probability of rolling both 1s is:
P = 1/6 × 1/6 = 1/36

name their favorite food. The results showed that
24 of the boys named pizza as their favorite food.
What percentage of the boys in the survey named

4%
Step-by-step explanation:
Percentage = Number of boys who named pizza [tex]\div[/tex] Total number of boys [tex]\times 100[/tex]
Percentage = [tex]\frac{24}{600} *100=0.04*100=4[/tex]

Answer:
y = [tex]\frac{20-2x}{5}[/tex]
Step-by-step explanation:
Given
2x + 5y = 20 ( isolate the term in y by subtracting 2x from both sides )
5y = 20 - 2x ( divide both sides by 5 )
y = [tex]\frac{20-2x}{5}[/tex]
Water covers 70.8%, or about 3.61 108 km2, of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)
This question was not properly written
Complete Question
Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)
Answer:
510,000,000 million km²
Step-by-step explanation:
Let us represent the total surface area of the earth as = x
We are told in the question that:
Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface.
70.8% = 0.708
Hence,
0.708 × x = 3.61 × 10⁸
x = 3.61 × 10⁸/0.708
x = 361000000/0.708
x = 509,887,005.65km²
Therefore, the total surface are the earth approximately to the nearest million = 510,000,000 million km²

The pressure exerted on an object under water increases by 1 atmosphere every 33 feet below the surface of the water. At sea level, the pressure is l atmosphere. Which equation gives the total pressure p, in atmospheres, exerted on an underwater object at a depth of f feet below sea level? A) P 33 B) p 33f C) p 33f+ 1
Answer:
ooooooooooooooooooooooooo
The linear function that gives the total pressure exerted on an underwater object at a depth of f feet below sea level is given by:
p = l + 0.0303f.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem:
The pressure changes by 1 for each 33 feet of depth, hence m = 1/33 = 0.0303.The initial pressure is of l, hence b = l.Thus, the function is given by:
p = l + 0.0303f

Evaluate the expression for m = –38.
–23(m + 39) =
Answer: -23
Step-by-step explanation:
Since we are given the value of m, all we have to do is to plug m into the expression and solve.
-23(-38+39) [parenthesis]
-23(1) [multiply]
-23
Now, we know that the expression is -23 when m=-38.
