It says last 5 bowling scores but there’s only four numbers listed just fyi
To find the mean, add all the numbers up and then divide by how many numbers you just added.
So, let’s add 68, 75, 90, 80
That equals 313. Now let’s divide by four, since we added four numbers together.
313 divided by four equals 78.25
So out of those four scores you gave me, her average was score 78.25
Hope this helped :)
Let
x = measure of the angle
y = measure of the supplement
By definition of supplementary, the two angles add to 180 degrees, so
x+y = 180
This is the first equation.
The second equation is y = 3x-16 since we're given the info that "the supplement is 16 degrees less than three times the angle"
--------------------------
The system of equations is
x+y = 180
y = 3x-16
Focus on the first equation x+y = 180, plug in y = 3x-16, and solve for x
x+y = 180
x+3x-16 = 180 ... y is replaced with 3x-16
4x-16 = 180
4x-16+16 = 180+16
4x = 196
4x/4 = 196/4
x = 49
Because x = 49, we can use this to find y
y = 3x-16
y = 3*49-16
y = 147 - 16
y = 131
-------------------------------------------------------------
Final Answers:
The measure of the angle is 49 degrees
The measure of the supplement is 131 degrees
Given:
In △ABC and △PQR, AB = 5 cm , BC = 6 cm , AC = 8 cm , PQ = 6 cm , QR = 5 cm , PR = 8 cm.
To find:
The correct congruency statement for the given triangles.
Solution:
In △ABC and △PQR,
(Given)
(Given)
(Given)
All three corresponding sides of both triangles are equal. On comparing both triangle, it is conclude that the corresponding angles of A, B, C are R, Q, P respectively.
(SSS congruency postulate)
Therefore, the correct option is C.
Answer
3.07, 3.1, 3 1/8, 3 1/10
hope this helps and have a wonderful day :)
