Answer:
$43.2Step-by-step explanation:
Step one:
given data
the total cost function is
c=2.60b + 12
Step two:
Required is c, when b= 12
substitute b=12 we have
c=2.60(12) + 12
c=31.2+ 12
c=43.2
the total cost = $43.2

Oliver estimates the weight of of his cat to be 16 pounds. The actual weight of the cat is 14.25 pounds. What is the percent error of Oliver's estimate rounded to the nearest tenth of a percent.
Given:
Estimated weight of a cat = 16 pounds
Actual weight of that cat = 14.25 pounds
To find:
The percent error to the nearest tenth of a percent.
Solution:
We know that,
[tex]\text{Percent error}=\dfrac{\text{Estimated value - Actual value}}{\text{Actual value}}\times 100[/tex]
Using the above formula, we get
[tex]\text{Percent error}=\dfrac{16-14.25}{14.25}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{1.75}{14.25}\times 100[/tex]
[tex]\text{Percent error}=0.122807\times 100[/tex]
[tex]\text{Percent error}=12.2807[/tex]
Round the percent error to the nearest tenth of a percent.
[tex]\text{Percent error}\approx 12.3[/tex]
Therefore, the percent error is 12.3%.

A) 6x-6
B) 2x-18
C) 6x-18
D) 5x-3
Answer:C 6x-18
Step-by-step explanation:
3 times 2 equals 6 and 3 times -6 will give you -18
Answer:
The solution is C) 6x-18
Step-by-step explanation:
3(2x-6)

-1 1/3 plus 3/4 (fraction form)
Answer:
[tex]\boxed{-\frac{7}{12} }[/tex]
Step-by-step explanation:
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
→ Make both denominators the same
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}[/tex]
→ Convert mixed number into improper fraction
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}[/tex]
→ Do the -16 + 9 and leave 12 as the denominator
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}[/tex]
The required simplification o f[tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12
To simplify -1 1 / 3 plus 3 / 4 into fraction form.
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions constituting the Whole. And it is represented as a / b, where a = numerator and b = denominator.
Since the given problem is
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
We need to simplified it into fraction form like a / b.
[tex]=-1\frac{1}{3}+\frac{3}{4} \\= -2/3 + 3/4[/tex]
= ( -8 + 9 ) / 12
= -1 / 12
Thus, The required simplification of [tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12.

Lara charges $12 per hour for babysitting. If f represents Lara's total fee after babysitting for h hours, which equations can be used to model the situation?
Answer: f= 12h , where f = Lara's total fee after babysitting for h hours.
Step-by-step explanation:
Given: Lara charges $12 per hour for babysitting.
Charge per hour = $12
Let h= Number of hours
Total charge = (Charge per hour) x (Number of hours)
If f = Lara's total fee after babysitting for h hours.
then, f= 12h
Hence, the required equation to model the situation : f= 12h

If the total trip takes 1 and one-half hours, which equation can be used to find x, the distance in miles from Juan’s house to the park? Distance (mi) Rate (mi/hr) Time (hr) Trip to Park x 4 mph Trip to Home x 6 mph StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 and one-half 4 x + 6 x = 1 and one-half 4 x + 6 x = 1
Answer:
The distance traveled equals the speed v multiplied by the time t
:
Since the speed varies, and we only know the total time, we must rewrite this as:
If we separate this in the two 'directions', it should add up to one and a half:

A car enthusiast learns that a particular model of car, which costs $42,000 new, loses 25% of
its value every year. How much will the car be worth in 2 years?
If necessary, round your answer to the nearest cent.
Answer:
23 625
Step-by-step explanation:
[tex]42000 - 25\% = 31500 \\ 31500 - 25\% = 23625[/tex]
Answer:
The value of the car in 2 years will be 21,000 I believe.
Step-by-step explanation:
The car originally costs 42,000 dollars. Every year the car loses 25% of it's original value.
The first thing to do is multiply .25 by 42,000. This should give you 10,500.
(42,000)(.25) = 10,500
Next is to multiply 10,500 by 2 to cover the second year. Your answer should be 21,000.
(10,500)(2) = 21,000
Now subtract that from the original value. And you should get 21,000.
42,000 - 21,000 = 21,000
Best of Luck!
If this is not the answer then it is, $23,625.

Michael wants tto start a garmets business. He borrowed 50000 for 5 years at 14% from his friend. The intrest is compoudee semi-annually from his friend. What is the total amount he will have to pay back to his friend?Round to the nearest cent
Answer:
98,357.57
Step-by-step explanation:
The formula to find the total amount obtained using compound interest is given as:
A = P(1 + r/n)^nt
Where:
A = Amount returned or payed back.
P = Amount borrowed = 50,000
R = Interest rate = 14% = 0.14
T = Time = 5 years
n = number of time compounded = semi annually = 2
Hence,
A = 50,000(1 + 0.14/2)^2 ×5
A = 50,000(1 +0.07)^10
A = 98,357.57
The amount he is paying back to his friend is 98,357.57.

Answer:
Step-by-step explanation:
Given the formula for calculating the distance travelled expressed as;
s=1/2at^2
Given
a = 3
t = 10
Required
lower bound of s
Substitute the given values into the equation;
s=1/2at^2

The CEO of a company wants to determine whether taking the employees to a company retreat would boost their morale. He decides to survey a simple random sample of 50 of the 250 employees. Which of the following options would guarantee a simple random sample? asking the first 50 employees who come to work on Monday morning to take the survey telling the managers in each of the 5 departments to randomly select 10 people to take the survey giving each employee a unique number from 1 to 250 and randomly selecting 50 people to take the survey sending an email to all 250 employees asking them to complete the survey within the next couple of days
Answer:
b
Step-by-step explanation:
Among all the given options, the one that would guarantee a simple random sample is: “telling the managers in each of the 5 departments to randomly select 10 people to take the survey.” Hence, Option B is correct.
What is a random sample?An unprejudiced portion of a population is chosen in a simple random sampling. With this sampling technique, the possibility of selection bias is reduced because every person of the population has an exact equal probability of being chosen.
A simple random sample is a group of people chosen at random, all with the same probability, from a larger group of people in statistics. It involves a method of randomly choosing a sample.
Random sampling assures that the results of sample should be close to those that would have been found if the complete population had been measured. With the simplest random sample, each unit in the population has an equal probability of being chosen.
Therefore, Option B is correct.

Suppose there is a 1.9f drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 51.8f what will be the temperature when the plane reaches an altitude of 3,000ft??
Answer: 46.1f
Step-by-step explanation:
Simce there is a 1.9f drop in temperature for every thousand feet that an airplane climbs into the sky, when the airplane reaches an altitude of 3,000ft, the drop in temperature will be:
= 1.9f × 3
= 5.7f
Since the temperature on the ground is 51.8f, then the temperature will then be:
= 51.8f - 5.7f
= 46.1f
