Answer:
2.5
Step-by-step explanation:
because you can tell by the numbers and how close they are then u have to divide
Answer:
300ml
Step-by-step explanation:
As values are missing in your question, the complete question is:
In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is 6% alcohol and Solution B is 20% alcohol. She uses 400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 12% alcohol solution?
Considering x=ml of 20% solution B
Therefore, 400+x=ml of resulting 12% solution
Solution A alcohol+ solution B alcohol= Alcohol solution
6% (400)+ 20%x = 12%(400+x) ->(converting percentage into decimal)
.06*400+.2x=.12(400+x)
24+.2x=48+.12x
.08x=24
x=24/.08=300 ml
she used 300 milliliters of 20%Solution B in resulting mixture.
Answer:
Step-by-step explanation:
We want to evaluate:
for x=-2 and y=-4.
We substitute to get:
We now simplify to get:
<span>Given
situation : 2 improper fraction is multiplied. Now is the product always more
than than 1?
Yes, the product is always more than 1. Because take note that in improper
fraction, the numerator is always higher compare to the denominator of the
given fraction. That means when you divide the numerator from the denominator,
the answer would always be more than 1.
Example:
=> 5 / 4 x 4 / 2
=> 20 / 8 or equals to 5/2
now divide
=> 5 / 2
=> 2 1/2

Answer:
Option (C)
Step-by-step explanation:
Cost of ordering the number of shirts is represented by the function,
f(x) = 12.75x + 3.5
where x = number of players in the bowling team
Since number of players a bowling team can have,
6 ≤ x ≤ 10
Therefore, domain of the function: 6 ≤ x ≤ 10
For x = 6,
f(6) = 12.75(6) + 3.5
= 80
For x = 7,
f(7) = 12.75(7) + 3.5
= 92.75
For x = 8,
f(8) = 12.75(8) + 3.5
= 105.5
For x = 9,
f(9) = 12.75(9) + 3.5
= 118.25
For x = 10,
f(10) = 12.75(10) + 3.5
= 127.5 + 3.5
= 131
Therefore, for the given domain range of the function will be,
Range : {80, 92.75, 105.5, 118.25, 131}
Option (C) will be the answer.
