Answer:
B.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.
From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.
Now we check for these two ratios in each choice.
A.
1 is twice 1/2. Check
sqrt(3)/2 is sqrt(3) times 2. Check
B.
10 is twice 5, not twice 5/2. This does not check.
C.
2sqrt(2) is twice sqrt(2). Check
sqrt(6) is 2sqrt(2) time sqrt(3). Check
D.
6 is twice 3. Check
3sqrt(3) is sqrt(3) times 3. Check
Answer: B.
First turn the whole numbers into mixed fractions:
1 1/2
multiply the whole number by the denominator then add it to the numerator which will make 3/2
doing the same thing on 1 2/3, you get 5/3
finding the LCM of 5/3, 3/2 and 3/4, you get 12
multiplying 4/4 to 5/3, you get 20/12
multiplying 6/6 to 3/2, you get 18/12
multiplying 3/3 to 3/4, you get 9/12
now you can add them easily and you get 47/20
turning that into a whole fraction, you get 2 7/20
Answer:
295%
Step-by-step explanation:
#1 $2.49x6=14.94
#2 hourly rate 100-250
#3 they would have had to spend more than just $182.53 because the Bounce House cost a dollar V $150 hours and hour so you would have to add 150 x 8 and get your answer for that money so your total could not equal 180 2.53 therefore I believe this is a trick question
