sin(C) = 24/25cos(Z) = 5/13=============================================
Explanation:
The formulas we use are
sin(angle) = opposite/hypotenusecos(angle) = adjacent/hypotenuseThe fraction 15/39 reduces to 5/13 after dividing both parts by the GCF 3.

How can you tell if 2 functions are inverses of each other?
Answer:
If the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.

Roy has a 120-meter strip to work with.
How many 1 decimeter pieces can be cut from his strip
Answer:
1,200 one decimeter pieces can be cut
Step-by-step explanation:
Find how many 1 decimeter pieces can be cut by converting the 120 meters to decimeters.
In 1 meter, there are 10 decimeters.
So, convert 120 meters to decimeters by multiplying it by 10:
120(10)
= 1,200
So, there are 1,200 decimeters in the strip. This means that 1,200 one decimeter pieces can be cut, since 1,200 divided by 1 is 1,200.
So, 1,200 one decimeter pieces can be cut
Solve for x:−2(x+9)=−1(x+−1)+2
Answer:
A
Step-by-step explanation:
expanding the bracket, we would have
-2x -18 = -x+1+2
-2x+x= 3 +18
-x=21
x=-21
Answer:
A
Step-by-step explanation:
−2(x+9)=−1(x+−1)+2
Use distributive property
-2x - 18 = -1x + 1 +2
-2x - 18 = -1x + 3
+18 +18
-2x = -1x +21
+1x +1x
___________
-x = 21
we need to have a positive x so multiply x by -1. -x times -1 = x
What we do on the left side has to happen to the right side too
So, 21 times -1 = -21
Therefore, x = -21

can someone help me on this question i don't know if im correct I would appreciate it.
Answer: You are correct. The answer is B) 118 degrees
Nice work.
To get this answer, you simply subtract the given angle from 180
180-62 = 118
This is because angles RSU and UST are supplementary, as they form a straight line.
The theater sells two types of tickets: adult tickets for $15 and
child tickets for $11.
Last night, the theater sold a total of 147 tickets for a total of
$1889. How many adult tickets did the theater sell last night?
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets

Step-by-step explanation:
When writing coordinates₋₋also known as "points" on a coordinate plane₋₋you write it as (x point,y point) more simply written as (x,y).
So in both tables, you can see that there are several coordinates listed. Each with the same format (x,y).
If you compare the two tables, you can see that the numbers in the (x,y) position are the exact same for corresponding coordinates.
Now you can conclude what the answer is:
The x-coordinates in Table A are the same as the x-coordinates in Table B.

Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Answer:
A. It increased both her intensity and her workout time.
Step-by-step explanation:
A. It increased both her intensity and her workout time.
B. It decreased her intensity but increased her workout time.
C. It increased her intensity but decreased her workout time.
D. It decreased both her intensity and work out time
Last week = 4 miles per day
This week = 5 miles per day
Intensity refers to how hard one exercises.
Workout time refers to how long one exercises the body.
By adding a mile, she has increased how hard she exercises her body (intensity))
And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day
Mercury is at a distance of 46213267 km from the sun. If the value of this area is rounded off to the nearest one hundred, then the result would be .
Answer:
46,213,300 km
Step-by-step explanation:
46,213,267
in the above number ;
7 = units
6 = tens
2 = hundred
3 = thousand
1 = ten thousand
2 = hundred thousand
6 = million
4 = 10 million
to round off to the nearest hundred, look at the number in the tens (6). If this number is greater than or equal to 5, add 1 to the hundreds unit, if this is not the case, add zero
because 6 is greater than 5, add one to the hundred value
= 46,213,300 km

Which pair of equations represent PARALLEL lines? A) y=2x and y = -1/2x B) y=2x and y = -1/2 C) y=2 and y=-2 D)y=2x=-2
Answer:
None
Step-by-step explanation:
Step 1: Write all the equations in the form y=mx+c, where m represents the gradient.
Notably, the equations are in that form already.
Step 2: Compare which equation have same value of m
In our case, none, hence no parallel lines

Describe and correct the error in writing an equation of the line.
(Please no links or false answers)
Answer:
the mistake they made was the wrong offset from point (0,0) into the y direction. the incline of the line was correct.
the correct equation is y = 1/2×x - 2, because this line contains both points (4,0) and (0,-2)
Step-by-step explanation:
we are looking for a line equation
y = a×x + b
the 2 points give us 2 equations to solve for the 2 variables a and b :
0 = a×4 + b
-2 = a×0 + b
=> b = -2
=> -b = a×4, => a = -b/4 = 2/4 = 1/2
so, the right equation for the line going through both points is
y = 1/2×x - 2
the difference to the original equation is simply the offset from the x- axis in the y direction.
the original equation would be parallel to the correct equation but hit the y-axis at (0,4) instead of (0,-2), and it would hit the x-axis at (-8,0) instead of (4,0)

1. Why are all rectangles parallelograms, but all parallelograms are not rectangles?
2. What properties must a quadrilateral posses in order for the quadrilateral to be classified as a:
a) trapezoid
b) isosceles trapezoid?
Answer:
1: Because all lines on a rectangle never touch so it is a parallelogram. But all sides of a square don't touch either, so that's also a parallelogram. So not all parallelograms are rectangles since squares are also parallelograms
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. All internal angles of a rectangle are 90° while the internal angles of a parallelogram may differ
2. A quadrilateral just means anything with 4 sides (quad meaning 4 and lateral meaning sides) and it is 2-dimensional with straight sides.
Therefore, the trapezoid and isosceles trapezoid are quadrilateral
a) A quadrilateral must have a pair of parallel sides to be classified as a trapezoid.
b) A quadrilateral must have the left and right side to be of equal length and the base angles equal to be classified as an isosceles trapezoid
