Answer:
We know that the formula to mix chemical solutions is: C1V1 = C2V2
where C represents the concentration of the solute, and V represents volume in milliliters or ml.
In this case, we have:
0.06V1 = 0.15×350
Solving for 'V1' we have:
V1 = (0.15×350)/0.06 = 52.5/0.06 = 875
Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.
Direct variation is is when the x and y a direct relation
without constants added or subtracted
With being times by each other
so the only one that meets the definite is the first one
y = 0.5x means y is equal to half of x. So you know that every y is directly related to half of x
Answer: Reagan's pay was increased by 62%
Step-by-step explanation:
First, lets find the difference between the two pays:
$347,247 - $214,350 = $132,897
Let 214350 = 100%
Dividing 132,897 by 214350 to find the percent increase

Therefore, Reagan's pay was increased by 62%
Answer:
288 and 289 are the two pages.
Step-by-step explanation:
Answer:
Part a) 
Part b) 
Step-by-step explanation:
step 1
we know that
The diameter of the circle divide the circle into two equal parts
so
PM=MQ
Applying the <u>Intersecting Chord Theorem</u> (When two chords intersect each other inside a circle, the products of their segments are equal)


we have


substitute



step 2
Find the value of PQ
we know that

so


we have

substitute
