Answer:
2a - b = 5
Step-by-step explanation:
4a - 2b = 10
take out the highest common factor of the left side
2(2a - b) = 10
divide both sides by two
2a - b = 10/2
2a - b = 5
So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.
--> a changed into a√2
√2 changed in √2 * √2
= 2
So the hypotenuse of the 40-40-90 degree triangle is 2.
Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.
-> a is changed to a√3
2 is changed into 2√3
So, y is 2√3 or approximately 3.46 units.
Answer:
Be careful what you wish for.
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
13 x 4 = 52
13 represents # of cars
4 represents tires per car
52 represents total tires
52 tires - 7 damaged tires = 45 undamaged tires
0.8%=6
6/8=0.75(0.1%)
0.75*1000=750(100%)
Answer=750
Proof= 750*0.008=6
