its a sqaure so the angles are 90 degress each.
90 - 38 = 52
answer: C. 52
Answer:
c = 52*
Step-by-step explanation:
If we assume that both shaded triangles are equivalent, and we know that the total angle of a square's corner is 90*, to find the missing angles of the unshaded area (angle z) we just subtract 38 from 90.
90 - 38 = 52*.

Samantha is collecting quarters for a school fundraiser. She wants to wrap what she has already collected into coin rolls. Each coin roll holds 40 quarters. If Samantha has 479 quarters, how many coin rolls will she need?
Answer:12
Step-by-step explanation:
Given
Each coin roll can hold 40 quarters
There are a total of 479 quarters
So, no of coin roll [tex]=\dfrac{\text{Total quarters}}{\text{Holding capacity of each coin roll}}[/tex]
[tex]\Rightarrow \frac{479}{40}=11.975[/tex]
As no of coin rolls cannot be in decimal
[tex]\therefore[/tex] there are 12 coin rolls

business. Company A charges $40 per hour and a $100 equipment fee.
Company B charges $30 per hour and a $150 equipment fee. Let A represent
the amount Company A would charge for t hours of landscaping, and let B
represent the amount Company B would charge for t hours of landscaping.
Write an equation for each situation, in terms of t, and determine the interval
of hours, t, for which Company A is cheaper than Company B.
A=
B=
Answer:
Step-by-step explanation:
A= 40t + 100
B= 30t + 150
A = 40t + 100

According to the income section shown below from the 1040EZ form,
which of the following on line 2 would make the taxpayer ineligible to use this form?
A P E X ANSWER PLEASE I NEED ANSWER ASAP PLEASE AND THANK YOU!
Answer:
A) interest in the amount of $1,600
Sorry, this is late!
Step-by-step explanation:
Line 2 states that a taxpayer is ineligible to use the form if their total taxable interest is over $1,500. Answer A implies that the interest rate is $1,600 which applies perfectly.
The thing on line 2 that would make the taxpayer ineligible to use this form is D, None of the above.
What is a 1040EZ form?This refers to the tax form in the United States that is used for people below the age of 65 and have dependents that earn less than $100,000 yearly.
Hence, we can see from line 2, we can see that it is stated that taxable interest is more than $1,500 and the person becomes ineligible and none of the answer choices satisfies this, so option D is the answer.

In a class A of 25 students, 20 passed in first class; in another class B
of 30 students, 24 passed in first class. In which class was a greater
fraction of students getting first class?
Answer:
class A 20/25 = 4/5
class B 24/30 = 4/5
they are both the same
Answer:
Both classes have the same fraction (80% or 4/5).
Step-by-step explanation:
20 is 4/5 of 25, so 80% of students in Class A passed in first class.
24 is 4/5 of 30, so 80% of students in Class B passed in first class.
Both 20/25 and 24/30 simplify to 4/5, or 80%, so both classes have the same fraction of students passing.

1. what are the focus and the directrix to a parabola and how do they help you understand about a parabola ?
2. how are the center, radius, and a point on the circle expressed algebraically?
Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.

1 1/5 - 3/5 = 3/5
9 1/5 - 3/5 = 8 3/5
Answer:

Step-by-step explanation:
1 3/5 becomes 6/5. 6/5 - 3/5 = 3/5. 9 1/5 becomes 46/5. 46/5 - 3/5 = 43/5. 5*8=40 so 8 3/5.

Answer:
hello your question is incomplete attached below is the complete question
answer; [tex]\frac{\pi ^{2} }{16}[/tex]
Step-by-step explanation:
attached below is a detailed solution to the given question above
where :
cos 2x = 1-2sin^2x
cos2x = 2 cos^2x -1
sin^2 2x + cos^2 2x = 1
1-cos^2 2x = sin^2 2x
Answer:
[tex]\mathbf{ Volume (V) = \dfrac{\pi^2}{16} }[/tex]
Step-by-step explanation:
[tex]y = sin x .cos x \\ \\ A(x) = \pi [ sin \ x * cos \ x]^2[/tex]
[tex]= \pi sin^2 x* cos ^2x[/tex]
[tex]Volume (V) = \int ^{\pi/2}_{0} \pi \ sin^2 x \ cos^2x \ . dx[/tex]
[tex]=\pi \int ^{\pi/2}_{0} \Bigg [ \dfrac{1-cos \ 2x}{2} \times \dfrac{1 + cos \ 2x}{2} \Bigg ] \ . dx[/tex]
[tex]=\dfrac{\pi}{4} \int ^{\pi/2}_{0} \ [1 - cos^2 \ 2x] \ . dx[/tex]
