Answer:
x = 140° ∵ allied angles sum to 180°
Step-by-step explanation:
Allied angles are interior angles within two parallel lines and they add up to 180°. In this case, x and 40° add up to 180° since there are two horizontal parallel lines.
Evaluate for x = 3.

hey um, so i’m learning ab percentages in my math class so can someone please explain to me how to solve percent problems if that’s ok? thank you.
Answer:
It's pretty simple. For example, if it says there is a percentage increase on something like there is a jacket for $25 and there was a 15% increase, you multiply 25 by 1.15 to see what the new price is. But say if the same $25 jacket is on sale for 15%, then you can multiply 25 by .15, then subtract that from 25 or originally subtract the 15% from 100 which is 85 and multiply 25x.85 and get the answer directly.
Hope this helps! But this would be easier to explain with an example
Angie read 60 pages of a textbook in 2 hours. She turned on the TV and read 24 pages in 1 hour. Angie’s average reading rate with the TV on, is what percent of her average rate with the TV off? A. 75% B. 80% C. 85% D. 90%
Answer:
80%
Step by step explanation:
Hello! So Angie reads 60 pages in 2 hours, without the TV on. 60/2 is 30. She reads 30 pages an hour without the TV on, and 24 pages with the TV off. To find the percent of her reading rate with the TV on instead of off, we can just divide both of the reading rates. 24/30 is 0.8. Multiply that by 100 and you get 80% in percent form. There. Angie's reading rate with the TV on is 80% of her reading rate with the TV off. The answer is B: 80%.
Answer:
The answer is B.) 80%

Answer:
-3
Step-by-step explanation:
YOu first have to simply the equation first. -2x+5<7. You first subtract each side by 5, which gives -2x<2. Dividing both sides by -2 gives x>-1 (Remember you have to flip the signs ; D) So x has to be bigger than -1. -3 is the only number that is smaller than -1.
A nutrition label says that one serving out of a bag of chips has 3.7 grams of fat. how many grams of fat are there in 2.5 servings?
Step-by-step explanation:
1 serving = 3.7g of fat
=> 2.5 servings = 3.7g * 2.5 = 9.25g of fat.
Hence there are 9.25g of fat.
Answer:
2.5 servings of chips has 9.25 grams of fat.
Step-by-step explanation:
1 serving of chips has fat = 3.7 grams
We need to find how many grams of fat are there in 2.5 servings.
So, solving using unitary method:
If we are given grams of 1 serving, so multiplying it with 2.5 will give us grams of fats of 2.5 servings.
1 serving of chips has fat = 3.7 grams
2.5 servings of chips has fat = 3.7 * 2.5
= 9.25 grams
So, 2.5 servings of chips has 9.25 grams of fat.
Complete the proof.
Drag and drop the expression to correctly complete the proof of the polynomial identity (x−y)2+4xy=(x+y)2.
Answer:
See attached
Step-by-step explanation:
The proof is attached
Answer:
x^2-2xy + y^2 + 4xy = (x + y)^2
x^2 + 2xy + y^2 = (x + y)^2
(x + y)^2 = (x + y)^2
For the order of operations, Group of answer choices Multiplication, division and remainder is performed first Addition and subtraction is performed first Assignment is performed first Addition and subtraction is performed after multiplication, division and remainder Multiplication, division and remainder is performed after addition and subtraction Assignment is performed last
Answer: Addition and subtraction is performed after multiplication, division and remainder
Step-by-step explanation:
The correct order of operations is to calculate whatever is in the parenthesis first.
Then calculate multiplication and division depending on which comes first as you move from left to right.
Then addition and subtraction can be performed also depending on which comes first as you move left to right.
What is the range of the function f(x) = (x – 1)2 when the domain is {-5, 0, 5}?
9514 1404 393
Answer:
{1, 16, 36}
Step-by-step explanation:
Put the numbers in for x and see what the f(x)-values are.
(-5-1)^2 = (-6)^2 = 36
(0-1)^2 = (-1)^2 = 1
(5-1)^2 = 4^2 = 16
The range is the set of values {1, 16, 36}.
Factor the polynomal 4x3+8x2+12x.
Answer:4(3+4+3x)
Step-by-step explanation: This simplifies to 12+16+12x. The GCF is 4. So if you factor out 4, your answer will be 4(3+4+3x).
Diagnostic tests of medical conditions can have several types of results. The test result can be positive or negative, whether or not a patient has the condition. A positive test (+) indicates that the patient has the condition. A negative test (−) indicates that the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 200 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.
Assume the sample is representative of the entire population. For a person selected at random, compute the following probabilities. (Enter your answers as fractions.) Test Result Test Result Column Total Condition Present 105 24 129 Condition Absent 25 46 71
(a) P(+ condition present): this is known as the sensitivity of a test.
(b) P(- | condition present); this is known as the false-negative rate.
(c) Pcondition absent); this is known as the specificity of a test.
(d) P(+ | condition absent); this is known as the false-positive rate
(e) Prcondition present and +); this is the predictive value of the test
(f) P(condition present and-)
Answer:
a. 105/130
b. 25/130
c. 46/70
d. 24/70
e. 105/200
f. 25/200
Step-by-step explanation:
A.
P(+|condition present)
= Prob(+ and condition present)/condition present
= 105/130
B.
P(-|condition present)
= Prob(- and condition present)/condition present
= 25/130
C.
P(-|condition absent)
= Prob(- and condition absent)/condition absent
= 46/70
D.
P(+ | condition absent)
= Prob(+ and condition absent)/condition absent
= 24/70
E.
P(condition present and +)
= 105/200
F.
P(condition present and -)
= 25/200
Alexis and Paige work together as photographers for the local newspaper. Alexis is paid $25 for each news story she shoots and an additional $5 per picture. Paige makes $15 for each news story and $10 per picture. Write an expression to show how much the newspaper will pay if Alexis and Paige are hired together. Use p as the variable for pictures
Answer:
The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.
Step-by-step explanation:
Given that:
Alexis charges $25 for each news story and $5 per picture.
Let,
n represent the number of news stories and p represent the number of pictures.
Alexis' total charges = [tex]25n+5p[/tex]
Paige charges $15 for each news story and $10 per picture.
The variables will be same.
Paige's total charges = [tex]15n+10p \\[/tex]
Alexis and Paige's charges will be added if newspaper hire them together.
Total charges paid by newspaper = [tex]25n+5p+15n+10p=40n+15p[/tex]
Hence,
The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.
