Answer:
Step-by-step explanation:
Perimeter of a triangle equals side 1 plus side 2 plus side 2
P = s1 + s2 + s3 side 1 = side 2 = x
x/side 3 = 5 / 3
x = (5/3) side 3
x (3/5) = side 3
perimeter = 65 slove for x
65 = x + x + 3x/5
325 = 5x + 5x + 3x
325 = 13X
25 = x equal side 1 and side 2
side 3 = 25(3/5) = 15
Solve the equation.

Step-by-step explanation:
Angles in circle solve for each variable
Answer:
x degree = 112 degree
Step-by-step explanation:
let the intersecting point of two cords be O.
then arc QR = angle QOR
which means ; 68 degree = angle QOR
Now,
angle QOR + angle POQ = 180 degree ( linear pair )
or, 68 degree + angle POQ = 180 degree
hence, angle POQ = 112 degree,.

the answer is C
Step-by-step explanation:
i just took the test
Answer:
C. Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a reflection and a translation of ABC.

NEED HELP QUICK!!!!! A set of data includes the point (17,3.8) and has the regression equation y=-25x+436. What is the residual for this point
Given:
The regression equation is:
[tex]y=-25x+436[/tex]
The given point is (17,3.8).
To find:
The residual for the given point.
Solution:
We have,
[tex]y=-25x+436[/tex]
Substituting [tex]x=17[/tex], we get
[tex]y=-25(17)+436[/tex]
[tex]y=-425+436[/tex]
[tex]y=11[/tex]
The predicted value at [tex]x=17[/tex] is 11.
The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.
Formula for residual:
Residual = Observed value - Predicted value
Residual = [tex]3.8-11[/tex]
Residual = [tex]-7.2[/tex]
Therefore, the residual for the given point is -7.2.

Tom earns $16 a week mowing lawns. He spends 1 4 of his earnings on lunch and 1 2 of his earnings on music. He saves the rest. How many dollars does Tom save? Tell how you found the answer
Answer:
32 dollars
Step-by-step explanation:
I think the answer is $32 because 14-12 is 2 and if you multiply 16 times 2 that's how I got the answer. I could be wrong I am sorry if I am.

Answer:
x=29
Step-by-step explanation:
cuz it's a 90 degree angle so 90-32 is 58 and divide it by 2 is 29 which would be x=29
Find the value for a.
Answer:
a = 25
Step-by-step explanation:
The exterior angles of a polygon sum to 360°
Sum the exterior angles and equate to 360
a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is
4a + 260 = 360 ( subtract 260 from both sides )
4a = 100 ( divide both sides by 4 )
a = 25

An company charges an initial fee of $350, plus $50 for each additional service added.
Which function can be used to find y, the total amount a customer would pay after n services were added.
Answer:
Y=250+50n
Step-by-step explanation:
Well since y in this case is total cost that is basically (f) the function range.
The domain in this case is the 250 one time fee and the 50 buks per services.
A student is 90 cm tall and growing at a rate of 3 cm per month. At this rate, in how many months will the student grow to a height of 132 cm?
Answer:
14 months
Step-by-step explanation:
14x3=42
42+90= 132
21) Which expression is equivalent to 6(7x − 4)? A) 13x − 10 B) 13x − 24 C) 42x − 10 D) 42x − 24
Answer:
Answer is D) 42x − 24
Step-by-step explanation:
Opening the expression given in question
6(7x − 4)
6 will be multiplied by both items present inside parenthesis.
it can be written as
={(6 * 7x) - (6*4)}
=42x-24
Hope that clears the question.

Step-by-step explanation:
Find the slope of each line.
Answer:
C) 1
Step-by-step explanation:
Slope = change in y over change in x
In the graph shown as y goes up 1 x goes up 1
so slope = 1/1 or 1
The slope equation is y=mx+b.
b is where the line crosses on the y axis, also known as the y-intercept.
m is the slope, which you are trying to find.
y and x are the points on the graph.
The slope is 3/3, which can be turned into 1, so the answer is c.
Write an equation of the parabola with focus (0, -3) and vertex at the origin. Use z for the independent variable.
Answer:
z^2 = -12y
or y = -(z^2/12)
Step-by-step explanation:
Answer:
z^2 = -12y
Step-by-step explanation:
Given the vertex at origin;
This is same as (0,0)
The focus (0,-3)
The general form is;
(z-h)^2 = 4p(y-k)
(h,k) is the vertex (0,0); so h = 0 and k = 0
The focus is given as;
(h,k + p)
so ;
k + p = -3
but k =0
so p = -3
Thus, the equation of the parabola is;
(z-0)^2 = 4(-3)(y-0)
z^2 = -12y
Did I choose the correct answer?
Answer:
11.90
Step-by-step explanation:
oh yes sorry I didn't see what you chose lol
Answer:
Yes
Step-by-step explanation:
Rounding two decimal points mean there will be two numbers behind the decimal and since 6 is more than 5 and influences the result of the 9 the answer would be 11.90. It could be 11.9 but having said there is two decimal places there should be a 0 hope this helps!!
