Hailey was given a box of assorted chocolates for her birthday. Each night, Hailey treats herself to some chocolates. The number of chocolates remaining in the box tt days after Hailey's birthday can be modeled by the equation C=-4t+24.C=−4t+24. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
y intercept is 24 (i think)
Step-by-step explanation:
-4t is x
+24 is y
Answer:
C=30-5t
Step-by-step explanation:
The y-intercept of the function is 30 which represents the number of chocolates in the original box.
that's the correct answer^^^^
Foster is centering a photo that is 5 - inches wide on a scrapbook page that is 16 inches wide. How far
2
from each side of the page should he put the picture? Enter your answer as a mixed number.
9514 1404 393
Answer:
5 1/2 inches
Step-by-step explanation:
The page is 16 -5 = 11 inches wider than the photo, so the margin on either side needs to be 11/2 = 5 1/2 inches.
Determine the value of x.
Help me please please please!
Answer:
X = 12
Step-by-step explanation:
Since each angle is equivalent to each other, you can write the equation:
(9x-3) = (7x+21)
Then Simplify.
Subtract both sides by 7x
2x-3=21
Add 3 To Both Sides
2x=24
Divide by 2
X = 12
Answer:
9x-3=7x+21
9x=7x+24
2x=24
x=12
Step-by-step explanation:
(9x-3) and (7x+21) are corresponding angles that means that they are congruent. So they equal each other.
Given \sec A=\frac{14}{\sqrt{171}}secA= 171 14 and that angle AA is in Quadrant I, find the exact value of \csc AcscA in simplest radical form using a rational denominator.
Answer:
Step-by-step explanation:
[tex]sec A=\frac{14}{\sqrt{171} } \\cos ~A=\frac{\sqrt{171} }{14} \\sin ~A=\sqrt{1-cos^2A} =\sqrt{1-\frac{171}{196} } =\sqrt{\frac{196-171}{196} } =\sqrt{\frac{25}{96} } =\pm\frac{5}{14} \\csc A=\pm \frac{14}{5}[/tex]
as A is in quadrant 1
[tex]so~csc~A=\frac{14}{5}[/tex]
in quadrant 1 both sin A and csc A are positive.
Simplify the expression
1/5v+3/10v
[tex]\frac15v+\frac3{10}v=\frac2{10}v+\frac3{10}v=\frac5{10}v=\frac12v[/tex]

I participated in a math competition but I did not do very good. Does anybody have some tips?
Find the EXACT value of sec (-120 degrees)
Well sec(-120) = 1/cos(-120).
We know that cos(-120) = -1/2.
So, 1/(-1/2) = -2.
This means that sec(-120) = -2.

Rachelhasalreadywritten10pages,andsheexpectstowrite1pageforeveryadditionalhourspentwriting.HowmanyhourswillRachelhavetospendwritingthisweekinordertohavewrittenatotalof27pages?
Answer:
17 hours
Step-by-step explanation:
Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?
The illustration can be modelled using the equation
y = 10 + 1(x)
y = 10 + x
Where,
y = total number of pages
x = number of hours
10 = pages already written
If y = 27 pages, find x
y = 10 + x
27 = 10 + x
27 - 10 = x
17 = x
x = 17 hours
Rachel have to spend 17 hours writing this week in order to have written a total of 27pages

Find the slope of the line through the following points. (-1, -4) and (-3,4)
A. 1/4
B. -1/4
C. 4
D. -4
Answer:
The answer is C, the slope is 4.
Step-by-step explanation:
Finding slope using two given points is easy. You need to do (y2-y1/x2-x1)
(-1,-4) the -1 is x1 and the -4 is y1. (-3,4) the -3 is x2 and the 4 is y2.
You plug them into the formula giving you
(4-(-4)/ -3-(-1)= 8/-2= 4

Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean) = $276,000 and sigma (standard deviation – measure of dispersion) = $32,000. Calculate the probability that the next house in the community will sell for between $276,000 and $325,000.
Answer:
0.43715
Step-by-step explanation:
We solve using z score calculator
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $276,000
σ is the population standard deviation = 32,000
For x = $276,000
z = 276,000 - 276,000/32000
z = 0
Probability value from Z-Table:
P(x = 276000) = 0.5
For x = $325,000
z = 325,000 - 276,000/32000
z = 1.53125
Probability value from Z-Table:
P(x = 325000) = 0.93715
The probability that the next house in the community will sell for between $276,000 and $325,000 is
P(x = 325000) - P(x = 276000)
= 0.93715 - 0.5
= 0.43715
A circus audience sits in rows around the performing ring. There are 9 seats in each row. How many rows will need to be set up if 513 people are expected to attend the show?
Answer:
57 rows
Step-by-step explanation:
Since each row will have a total of 9 seats, then we would simply need to divide the total number of individuals that will attend the show by 9 in order to calculate the number of rows that need to be set up around the performing ring.
513 / 9 = 57 rows
Therefore, we can see that we would need a total of 57 rows of 9 chairs each in order for there to be enough chairs to seat 513 people.
How do you reduce a ratio?
How to Simplify a Ratio A : B when A and B are both whole numbers
List the factors of A
List the factors of B
Find the greatest common factor of A and B, GCF(A, B)
Divide A and B each by the GCF
Use the whole number results to rewrite the ratio in simplest form
If the GCF = 1 then the ratio is already in simplest form.
How to Simplify a Ratio A : B when A and B are not whole numbers, in this order
If A or B are mixed numbers convert mixed numbers to improper fractions
If A or B are decimal numbers multiply both values by the same factor of 10 that will eliminate all decimal places
If one value is a fraction and the other a whole number, reduce the fraction to a whole number if you can or turn the whole number into a fraction by giving it a denominator of 1.
If both A and B are fractions and have like denominators, multiply both fractions by the denominator to eliminate it and you are left with two whole numbers
If both A and B are fractions and have unlike denominators, find the LCD(A, B) and rewrite the fractions with the LCD as the denominator. Multiply both fractions by the denominator to eliminate it and you are left with two whole numbers
If both A and B are whole numbers, Find the greatest common factor of A and B, GCF(A, B), and divide A and B each by the GCF
Example: Simplify the ratio 6 : 10
The factors of 6 are: 1, 2, 3, 6
The factors of 10 are: 1, 2, 5, 10
Then the greatest common factor of 6 and 10 is 2
Divide both terms by 2
6 ÷ 2 = 3
10 ÷ 2 = 5
Rewrite the ratio using the results. The simplified ratio is 3 : 5.
6 : 10 = 3 : 5 in simplest form
Answer:
List the factors of A.
List the factors of B.
Find the greatest common factor of A and B, GCF(A, B)
Divide A and B each by the GCF.
Use the whole number results to rewrite the ratio in the simplest form.

the sum of the interior angles in a pentagon
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540
