1.
List the scores:
(2) 60
(1) 65
(5) 75
(1) 95
(1) 100
Find the chart with those quantities: Chart A
2. Find the mean:
75 + 60 + 75 + 100 + 75 + 75 + 75 + 95 + 60 + 65 = 755
755/10 = 75.5
Subtract the mean from Ashley’s score:
60 – 75.5 = -15.5
The answer is D.
Answer:
Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.
Step-by-step explanation:
Let the number of awards Tommy won be x.
Number of awards Ali won -> x+3
Number of awards Jack won -> 2x
Subtract 3 from both sides:
Divide both sides by 4:
(Tommy)
(Ali)
(Jack)
Take a look at the order of the letters of ur triangles.
ABC and PQR.....it says they are congruent....so they r equal.
And the order of the letters means : < A = < P, and < B = < Q, and < C = < R.
so if < B = < Q....set them equal to each other and solve for v
3v + 4 = 8v - 6
6 + 4 = 8v - 3v
10 = 5v
10/5 = v
2 = v
now we sub our 2 in for v
< B = 3v + 4......3(2) + 4 = 10
< Q = 8v - 6.......8(2) - 6 = 10
so < B and < Q both equal 10 <==
First, we must find angle c:
180 - (73 + 42) = 65 degrees
Then, we use the question fro, the law of sine, which is:
angle A/ side A = angle B/ side B = angle C/ side C
The side this is opposite to the angle, it's the angle that we use. So, opposite to angle C is 28.7 . We have the equation:
65°/28.7 = 73°/a
Cross multiply and divide, and we get a = 32.2
