Answer:
Apple- 14 Maple- 154
Step-by-step explanation
Since 11 x n - n is equal to a number that ends in 10, 20 etc. and the number has to be a multiple of 11 for the maple tree, and the difference has to stay the same throughout two all we need to find is 15 x n = a number that is divisable by 10. 15 x 10 = 150 so that's the age of the trees this year, and the difference between the trees is 140 so it corresponds with our rule. and the multiple of 11 that the difference is 140 is 11 x 14 = 154 and 154 - 11 = 140. Therefore the apple tree is 14 years old and the maple tree is 154 years old.
What is y-4=2(x+3) in standard form
Answer:
2x - y = -10
Step-by-step explanation:
Standard form: x + y = n
y - 4 = 2x + 6
y = 2x + 6 + 4
y = 2x + 10
2x - y = -10
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.
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

C. 1, 0, and 3
D. 3, 0, and 1
Answer:
C

Step-by-step explanation:
f(x) factors as
f(x)=x(x+1)(x-3)
so has zeros of x = -1, 0, 3 because these values make the factors be zero.

The formula s=12at ^2 is used to calculate the distance s travelled by a bike when a=3 and t=10, each correct to the nearest integer, calculate the lower bound of the distance s
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
S = 1/2(3)(10)^2
S = 1/2 * 3 * 100
S = 3 * 50
S = 150
Hence the lower bound of distance S is 150
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
Jody works at the finish line and gets $36 each day he works plus $1.50 for each pair of shoes he sells. Write a function to represent the total (y) he will make in one day in relation to the number of shoes he sells.
Answer: y=36+1.50x
Step-by-step explanation:
Given: Daily wages = $36
Commission per pair of shoes he sells = $1.50
Let y= Total he will make in one day by selling x shoes .
Total earnings per day = Daily wages + Commission (Number of shoes)
y=36+1.50x
Hence, a function to represent the total (y) he will make in one day in relation to the number of shoes he sells: y=36+1.50x

-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.

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%.

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.

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.
