Find the measures of two complementary angles if the difference in their measures is 16.
Answer:
One of the angles is 53 degrees and the other is 37 degrees.
Step-by-step explanation:
Let x be equal to the measure of the first angle.
Let y be equal to the measure of the second angle.
Because x and y are complementary, they add up to 90 degrees.
x+y=90
The question tells us that x and y have a difference of 16.
x-y=16
Now that we have our two equations, we can use the method of elimination to find the value of x (process is in the picture attached). We do this by adding the two equations since y will cancel out.
x=53
Finally, we can plug x back into either of the original equations to find the value of y.
x+y=90
53+y=90
Subtract both sides by 53 to isolate y
53+y-53=90-53
y=37

The finance charge for this payment schedule is $450 if Ken and Marcy plan to have their kitchen remodeled at a cost of $6,000.
What are monthly expenses?It is defined as the expenses incurred by a single entity on a monthly basis, it consists of basic utilities, food, etc.
We have;
Ken and Marcy plan to have their kitchen remodeled at a cost of $6,000.
The carpenter suggests they pay $600 down, followed by 18 monthly payments of $325.
The finance charge = 600 + 325×18 - 6000
= 600 + 5850 - 6000
= 6450 - 6000
= $450
Thus, the finance charge for this payment schedule is $450 if Ken and Marcy plan to have their kitchen remodeled at a cost of $6,000.

One week a student exercised 3 hours at school and another 2/3 of an hour at home. If 1/6 of the student’s total exercise came from soccer, how much time did the student spend playing soccer that week?
Answer:
36m 40s
Step-by-step explanation:
To find out how much time was spent on playing soccer, we need to find out the total number of hours spent on exercising.
Total amount of time for exercise = 3h + [tex]\frac{2}{3}[/tex]h
= [tex]\frac{11}{3}[/tex]h
Total amount of time for soccer = [tex]\frac{1}{6}[/tex] × [tex]\frac{11}{3}[/tex]h
= [tex]\frac{11}{18}[/tex]h
= 36m 40s

2. (08.03) A teacher gave her class two exams; 60% of the class passed the second exam, but only 48% of the class passed both exams. What percent of those who passed the second exam also passed the first exam? (2 points) 80% 12% 30% 48%
Only 80% students passed the second exam and also passed the first exam .
Conditional probability is used to find the probability of an event A given that event B has already occurred.
It is denoted by P(A/B)=P(A∩B)/P(B) .
In the given question
Let A be the event for students passed in first exam.
Let B be the event for students passed in second exam.
Given
Only 48% passed in both the exam that means
P(A∩B)=48%=0.48 ...(i)
and
60% students passed the second exam , that is
P(B)=60%=0.60 ...(ii)
To find the probability of students passed in second exam given that they passed in first exam , conditional probability is used that is P(A/B), denoted by
P(A/B)=P(A∩B)/P(B)
Substituting the values from equation (i) and (ii) we get
P(A/B) = 0.48/0.60
=48/60
Converting 48/60 to percent
=48/60*100
=80%
Therefore , Only 80% students passed the second exam and also passed the first exam , the correct option is 80%.

If an input of -9 is put into each of the machines below, what is each output?
b. Eric wants to get an output of 0. Can he do this with each machine? If so, how? If not, why not?
Function A
Function B
If an input of -9 is given to machine having Function A, then output will be 84 and if it is given to machine having Function B, then the output will be 3i-2.
The machine having Function A is given by y = x² + 3 and the machine having Function B is given by y = (√x) - 2.
Here, input will be the value of x and output will be the value of y as x id the independent variable and y is the dependent variable. If we put x = -9 in both the machines, then;
The output by machine A will be given by
y = (-9)² + 3
y = 81 + 3
=> y = 84
The output by machine B will be given by
y = (√-9) - 2
y = 3(√-1) - 2
=> y = 3i - 2.
Now, if Eric wants to get an output zero, he can get it by using machine B as Function A has square and addition both so any negative number will also give a positive result and the result will never be zero. But in Function B the result zero can be obtained by giving the input as 4 that is x = 4. The output will be given by:
y = (√4) - 2
y = 2 - 2
=>y = 0.

Find the angle between the given vectors. Round your answer, in degrees, to two decimal places. u=⟨2,−6⟩u=⟨2,−6⟩, v=⟨4,−7⟩
Answer:
[tex]\theta = 108.29[/tex]
Step-by-step explanation:
Given
[tex]u = <2,6>[/tex]
[tex]v = <4,-7>[/tex]
Required:
Calculate the angle between u and v
The angle [tex]\theta[/tex] is calculated as thus:
[tex]cos\theta = \frac{u.v}{|u|.|v|}[/tex]
For a vector
[tex]A = <a,b>[/tex]
[tex]A = a * b[/tex]
[tex]cos\theta = \frac{u.v}{|u|.|v|}[/tex] becomes
[tex]cos\theta = \frac{<2,6>.<4,-7>}{|u|.|v|}[/tex]
[tex]cos\theta = \frac{2*6+4*-7}{|u|.|v|}[/tex]
[tex]cos\theta = \frac{12-28}{|u|.|v|}[/tex]
[tex]cos\theta = \frac{-16}{|u|.|v|}[/tex]
For a vector
[tex]A = <a,b>[/tex]
[tex]|A| = \sqrt{a^2 + b^2}[/tex]
So;
[tex]|u| = \sqrt{2^2 + 6^2}[/tex]
[tex]|u| = \sqrt{4 + 36}[/tex]
[tex]|u| = \sqrt{40}[/tex]
[tex]|v| = \sqrt{4^2+(-7)^2}[/tex]
[tex]|v| = \sqrt{16+49}[/tex]
[tex]|v| = \sqrt{65}[/tex]
So:
[tex]cos\theta = \frac{-16}{|u|.|v|}[/tex]
[tex]cos\theta = \frac{-16}{\sqrt{40}*\sqrt{65}}[/tex]
[tex]cos\theta = \frac{-16}{\sqrt{2600}}[/tex]
[tex]cos\theta = \frac{-16}{\sqrt{100*26}}[/tex]
[tex]cos\theta = \frac{-16}{10\sqrt{26}}[/tex]
[tex]cos\theta = \frac{-8}{5\sqrt{26}}[/tex]
Take arccos of both sides
[tex]\theta = cos^{-1}(\frac{-8}{5\sqrt{26}})[/tex]
[tex]\theta = cos^{-1}(\frac{-8}{5 * 5.0990})[/tex]
[tex]\theta = cos^{-1}(\frac{-8}{25.495})[/tex]
[tex]\theta = cos^{-1}(-0.31378701706)[/tex]

Matt invested $300 into an account that had an annual interest
rate of 3.8% compounded monthly for 5 years. Chris invested
$350 into an account that had an annual interest rate of 3.5%
compounded continuously for 5 years. Determine which models
could be used to determine how much money would be in each
account after 5 years.
The amount of money that Matt and Chris have after 5 years will be $362.66 and $415.69, respectively.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]
Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
Matt put $300 into a five-year account with a 3.8% annual interest rate compounded on a monthly basis. Then the amount after 5 years will be
[tex]\rm A = 300\left (1 + \dfrac{0.038}{12} \right ) ^{12 \times 5}[/tex]
Simplify the equation, then we have
A = 300 x 1.2089
A = $362.66
Chris put $350 into a savings account with a 5-year compounded yearly return rate of 3.5 percent.
A = 350 (1 + 0.035)⁵
Simplify the equation, then we have
A = 350 x 1.1877
A = $415.69
The amount of money that Matt and Chris have after 5 years will be $362.66 and $415.69, respectively.
