Answer:
Step-by-step explanation:
- 5x + 17= 1/2( 4x - 6 + 9x + 4)
- 10x + 34 = 13x - 2
- 13x - 10x = 34 + 2
- 3x = 36
- x = 12
m∠QDC = 5*12 + 17 = 77
Put 8 into fraction form: 8/1
Put 1 2/5 into a mixed number: 1*5+2 as numerator and 5 as denominator (7/5)
Now multiply 8/1 by the reciprocal of 7/5, which is basically just the numerator and denominator flipped, so 5/7. This is like dividing.
8/1*5/7= 40/7
40/7= about 5.7.
So, your answer would be 5.7 batches, or 5 complete batches would be a better answer.
Answer:
The amount of popcorn needed to fill the paper cone is 
Step-by-step explanation:
we know that
The volume of a cone is equal to
In this problem we have
substitute
P ( work/ senior ) = 0.14
The attached table
required
P ( work/ senior )
This is calculated using:
P ( work/ senior ) = n ( work/ senior )/ n ( senior ).
n ( work/ senior ) = 5
n ( senior ) = 25 + 5 + = 35
So:
P ( work/ senior ) = 5/35
P ( work/ senior ) = 0.14
Add 25+5+5 (because that is all the numbers in the 'Seniors' row) and then take the 5 that is in the 'Work' column and put that over 25. (5/25 fraction as a percent is 14).
