Answer:
40
Step-by-step explanation:
Find the factors of 8 and 10
8=2*2*2
10 = 2*5
We take the greatest number of terms of each factor
2 has 3 as the greatest number
5 has 1
The least common multiple is
2*2*2 *5 = 40

Julia’s score is <em>y</em> and Tina’s score is <em>y</em> + 6.
Step-by-step explanation:
Let us take Julia’s score be <em>y</em>.
First Tina scored 4 points more than Julia, so the expression is <em>y</em> + 4.
Then, Tina earned 2 points as extra credic, now the expression becomes
(y + 4) + 2 = y + 6.
Hence Julia’s score is <em>y </em>and Tina’s score is <em>y</em> + 6.
X=3/4

Answer: The Answer is C) 31 Units
Step-by-step explanation:
Let
F1------------------------- > airplane speed <span>150 mi / h East
F2-------------------------- > </span>wind speed <span>30 mi / h North
calculate the resultant force R
F1x=150 F1y=0 F2x= 0 F2y=30
Rx=F1x+F2x------------- >150+0 ---------------- >Rx=150
</span>Ry=F1y+F2y------------- >0+30 ---------------- >Rx=30
║R║=√150² 30²=√23400=152.97----- >153 mi/h
tan(theta)=Ry/Rx=30/150=0.20
arctan (0.20)=11.31 degrees-----------11.3 degrees
the answer is
actual speed 153 mi/h and direction 11.3 degrees North-East (I Quadrant)
