- ZA and B are complementary angles. If mA = (x + 28)° and m ZB = (4x - 8), then find the measure of ZA.
Answer:
42 degrees
Step-by-step explanation:
"Complementary" means the angle measures add up to 90 degrees.
[tex]m\angle A+m\angle B =90^\circ\\(x+28)+(4x-8)=90\\5x+20=90\\5x=70\\x=14[/tex]
Now plug in 14 for x in the expression for the measure of angle A.
[tex]m\angle A = 14^\circ+28^\circ =42^\circ[/tex]
How do angles of depression and elevation relate when solving problems involving right triangles?
Write an equation in slope-intercept form for the line that passes through the
given point and is parallel to the graph of the given equation.
(4, -6), y=-3/4x+1
Answer:
[tex]y=-\frac{3}{4}x-3[/tex]
Step-by-step explanation:
The slope will be the same as the one in the given equation since they are parallel, you can substitute the x and y of the given point into the given equation, replacing the 1 with m to get m in the equation.
I hope this helps :)
Which equation has a axis of symmetry of x=4 ?
I think you forgot to add the picture. However, any x = 4 equation will result in a graph with a vertical line on the x-axis. For example x = 20 will be a vertical line on x-axis 20.
Or, in a more difficult equation like this...
10x - 60 = 10
10x = 10 +60
10x = 70
x = 7,
where the graph looks like a vertical line with a point on the x axis on 7.
Erik read a total of 4 books over 2 months. After belonging to the book club for 17 months, how many books will Erik have read in all? plss hep me thank you!!
Answer: 34 books
Step-by-step explanation:
Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.
After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:
= 2 × 17
= 34 books
Terrel lives 2 5/6 blocks away from his best friends house. His school is 4 1/3 blocks away in the same direction. If he stops at his best friends house first how much farther do they have to walk to school.
Answer:
5/8 of a mile
Step-by-step explanation:
Let the distance from Post Office to Friend's house =D
7/8 + 5/6 + D =miles - Total distance from Georgia's house to a Friend's house.
42 minutes / 18 minutes per mile =2 1/3 miles - total distance from her house to a friend's house. So, we have:
7/8 + 5/6 + D = 2 1/3, solve for D
[21 + 20] / 24 + D = 2 1/3
41/24 + D = 2 1/3 subtract 41/24 from both sides
D =2 1/3 - 41/24
D =7/3 - 41/24
D =[56 -41] / 24
D = 15 / 24
D = 5/8 of a mile - the distance between the School and her Friend's house.
What would it be? thank you

If f (-8)= 0 and f (x)= x^3-x^2-58x+112, find all the zeros of f(x) write your answer in ascending order
Answer:
The zeros in ascending order are 2, 7, 8.
Step-by-step explanation:
Since f(-8) = 0, it means that (x + 8) is a factor of the function f(x)= x³ - x² - 58x + 112.
I have attached the long division of this to get the remaining factors of the polynomial function.
The remaining factor is;
x² - 9x + 14
Using quadratic formula via a calculator, we have; x = 7 and x = 2
Thus,the zeros of the polynomial function f(x)= x³ - x² - 58x + 112 in ascending order are;
2, 7, 8

The question is a model of rectangular stove top with four circular burners is shown the side length of the top stove and the diameter of the burners are labeled.which measurement is the best estimate of the area and square inches of the stove top that does not include the area of the burners?
Answer: see work
Step-by-step explanation:
Total area is 24x22=528
one circle area is (pi)3^2=9(pi)
that times 4 because of 4 circles =36(pi)
so the total are minus the circles now
in terms of pi the answer is 528-36(pi)
if pi = 3.14 the answer in 414.96

In 2018 sienna invested 5000. The value of the invest,ent increases by 3%each year compounded weekly if she doesn't make additional transactions, what will be the value of her investment in 2025
Answer:
6168.02
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value - 5000
R = interest rate = 0.03
N = number of years = 7
m = Number of compounding = 52
5000 x ( 1.000577)^52 x 7 = 6168.02
Liliana bought a book for $13. She is selling the book for $24. What is the percent markup on the price of the book? Round to the nearest hundredths place.
Mila owns a small business selling used books. She knows that in the last week 83 customers paid cash, 16 customers used a debit card, and 41 customers used a credit card. Based on these results, express the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth
Answer:
the answer is 0.71
Step-by-step explanation:
it told me
The probability the next customer will pay with something other than a credit card is 0.71.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of customers paid cash = 83
Number of customers used a debit card = 16
Number of customers used a credit card = 41
Total number of customers = 140
The probability that the next customer will pay with something other than a credit card is
P(e) = (Number of customers paid cash + Number of customers used a debit card) / Total number of customers.
⇒ [tex]P(e)=\frac{83+16}{140}[/tex]
⇒ [tex]P(e)=\frac{99}{140}[/tex]
⇒ [tex]P(e)=0.7071[/tex] ≈ [tex]0.71[/tex]
Hence we can conclude that the probability the next customer will pay with something other than a credit card is 0.71.

If he continued painting at that rate,
how many rooms could he paint in
12 hours? Explain your reasoning.
Answer quick PLZZ no website
Answer:
5 rooms
