interest = principal x rate x time /100
I=prt/100
p=1400
r=16.5%
t=8
i=1400*16.5*8/100
i=14*16.5*8

Two women painted a barn. Barbara can paint it alone in 5 days, and Sara in 8 days. They
started to paint it together, but after 2 days, Sara got bored and Barbara finished alone. How
long did it take her to finish?
Answer: she will need 2.8 days to finish the work.
Step-by-step explanation:
Let's define:
D = number of days.
B = rate at which Barbara paints a barn
S = rate at which Sara paints a barn
We know that Barbara can paint a barn in 5 days, then:
B*5 days = 1 barn
B = 1/5 barns per day.
And we know that Sara can paint it in 8 days, then:
S*8 days = 1 barn
S = 1/8 barns per day.
Now, when they work together, their rates are added.
Then if they work together for two days, they paint a total of:
(1/5 barns per day + 1/8 barns per day)*2 days
(8/40 barns per day + 5/40 barns per day)*2 days
(13/40 barns per day)*days = 26/40 barns
Now Sara needs to paint he other 14/40 barns in her own, she will need D days, then:
(1/8 barns per day)*D = 14/40 barns
D = (14/40 barns)/(1/8 barns per day) = (14*8/40) = 2.8 days.
So she will need 2.8 days to finish the work.

Mohamed surveyed his class on their favorite candy bar. 8 picked Snickers. 6 picked Kit Kats. 6 picked Milky Ways. If he applied the results of his survey to the whole school of 1500 people, about how many students would choose Snickers?
Answer:
600 students
Step-by-step explanation:
there were 20 students surveyed because 6 + 6 + 8 = 20 there were 8/20 who picked snickers then you have to find the proportions 20 * 75 = 1500 you then multiply 8 * 75 which equals 600 so in the end out of 1500 students 600 will pick snickers
7x - 14=35 what value of x makes this equation true
Hello there, and welcome to Brainly!
In the following equation, you are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 14 to both sides of the equation:
7x - 14 (+14) = 35 (+14)
7x = 35 + 14
7x = 49
Next, divide 7 from both sides:
(7x)/7 = (49)/7
x = 49/7
x = 7
7 is the value for x that will make the equation true.

5. 9(7x - 4) = 27
First, distribute 9 to all terms within the parenthesis:
9(7x - 4) = 27
(9 * 7x) - (9 * 4) = 27
63x - 36 = 27
Next, isolate the variable, x. Do the opposite of PEMDAS.
First, add 36 to both sides:
63x - 36 (+36) = 27 (+36)
63x = 27 + 36
63x = 63
Isolate the variable, x. Divide 63 from both sides:
(63x)/63 = (63)/63
x = 63/63 = 1
x = 1

6. 5(3x + 8) = 175
First, distribute 5 to all terms within the parenthesis:
5(3x + 8) = (5 * 3x) + (5 * 8) = 15x + 40
15x + 40 = 175
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 40 from both sides:
15x + 40 (-40) = 175 (-40)
15x = 175 - 40
15x = 135
Next, divide 15 from both sides of the equation:
(15x)/15 = (135)/15
x = 135/15 = 9
x = 9

Which statement describes the domain of the function
Answer:
D: All real numbers except x=-1 and x=1
Step-by-step explanation:
Step-by-step explanation:
The domain of the rational expression is when the denominator is defined. (non-zero)
When the denominator is 0,
4x² - 4 = 0.
=> x² - 1 = 0, (x + 1)(x - 1) = 0, x = -1 or x = 1.
Hence the answer is all real numbers except x = -1 and x = 1.

Question 13 pts
Data from Ivy Tech's advising center shows the wait times as a normal distribution with the average as 20 min and a standard deviation as 5 min.
Using the empirical rule, what percent of students wait between 15 and 25 minutes?
What percent wait more than 20 min?
Using the empirical rule, what is the chance that someone waits less than 5 min?
Answer:
1. 68%
2. 50%
3. 15/100
Step-by-step explanation:
Here, we want to use the empirical rule
1. % waiting between 15 and 25 minutes
From what we have in the question;
15 is 1 SD below the mean
25 is 1 SD above the mean
So practically, we want to calculate the percentage between;
1 SD below and above the mean
According to the empirical rule;
1 SD above the mean we have 34%
1 SD below, we have 34%
So between 1 SD below and above, we have
34 + 34 = 68%
2. Percentage above the mean
Mathematically, the percentage above the mean according to the empirical rule for the normal distribution is 50%
3. Probability that someone waits less than 5 minutes
Less than 5 minutes is 3 SD below the mean
That is 0.15% according to the empirical rule and the probability is 15/100
