A carpenter wants to cut an 84 inches long board into two -pieces such that one piece is twice as long as the other piece. Set an equation and find the length of each piece.
Answer:
The shorter piece is 28 inches
The long piece is 56 inches
Step-by-step explanation:
First, we need to write an equation:
-> Let x be the shorter piece after they are cut.
84 inches = x + 2x
84 inches = 3x
28 inches = x
x = 28 inches
Now we will find the length of each piece,
-> The shorter piece is 28 inches
[] x = 28 inches
-> The long piece is 56 inches
[] 2x = 2(28) = 56 inches
Checking work:
56 + 28 = 84
-> This solution should work
7/(2sqrt(3) + 2sqrt(5)) + 5/(3sqrt(2) + 8sqrt(5))

Assuming that the value of x is 4, and the value of y is 6, what is the value of the following expression? (x - y)**2 > y TypeError True Undefined False
Considering the given expression and the numerical values, it is found that it's value is False.
What is the expression given?The expression used in this question is given as follows:
[tex](x - y) \times 2 > y[/tex]
The values considered are x = 4 and y = 6, hence:
[tex](6 - 4) \times 2 > 6[/tex]

The solution to f(x)=g(x) is 0. Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, f(x)=g(x)
f(x)=-(x+2)(x-2) and g(x)=2|x+2|
Now, -(x+2)(x-2)=2(x+2)
-(x-2)=2
x-2=-2
x=-2+2
x=0
Therefore, option B is the correct answer.

I need to figure out estimation with decimals
Answer:
10 CDs
Step-by-step explanation:
First, let's round the cost of each CD to the nearest whole number.
6.98 ≈ 7.00The closest multiple of 7 to 75 is 77.
Then, it would make sense that Sean can buy 11 CDs. However, he has a little bit under 77 dollars, so he can only buy 10 CDs.(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)
Evaluate the expression. Give your answer in simplest form. 6/7 - 3/5=
Answer:

Step-by-step explanation:
To answer this question, you will need to find a common denominator.
The lowest common denominator between 7 and 5 is 35.
6/7 is equal to 30/35 and 3/5 is equal to 21/35
Use these numbers instead.
30/35 - 21/35 = 9/35

Blake is working his way through school. He works two part-time jobs for a total of 22 hours a week. Job A pays $5.70 per hour, and Job B pays $7.30 per hour. How many hours did he work at each job the week that he made $141.40.
Answer:
Job A= 12hrs and Job B= 10hrs
Step-by-step explanation:
first u need to make 2 equations, with 2 variables and the pay per hour for both jobs and let the first equal to the total pay at the end of the week
5.7x + 7.3y = 141.4
then the 2nd equation, let it equal to the total hours worked:
x + y = 22
you then make one of the variables the subject of the formula:
x= 22 - y
and substitute that formula into the first equation you would've made:
5.7(22-y) + 7.3y = 141.4 in this instance you then solve for y:
where y= 10hrs
given that y=10 you can then substitute it into either of the 2 equations:
x+y=22
x= 22-y
x= 22 - 10
x= 12hrs
therefore stating that Blake worked 12 hrs at job A and 10 hrs at job B

Is the average amount spent on textbooks per semester by accounting majors significantly
different from the average amount spent on text books per semester by management majors?
Answer this question with a 90% confidence interval using the following data from random
samples of students majoring in accounting or management. Discuss the assumptions
A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.
What is a confidence interval?
Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.
A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.
You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.
Finally, look up the resulting Z or t score in a table in order to find the level.

Step-by-step explanation:
I did this on the test and I got this specific answer correct :)
The required mean of the data set is 3/5, or approximately 0.6 inches.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
To find the mean of the data set, we need to add up all the values and divide by the total number of values.
1/4 + 1 1/3 + 2/3 + 1/4 + 1/2 = 1/4 + 4/3 + 2/3 + 1/4 + 1/2 (we convert all fractions to have a common denominator)
= 2/3 + 4/3 + 1
We need to convert these mixed numbers to improper fractions:
= 3
Now we divide by the total number of values:
= 3 ÷ 5
= 3/5
Therefore, the mean of the data set is 3/5, or approximately 0.6 inches.
