10 cubic centimeters of a 60% alcohol solution, would mean 10 x 60% = 6 cc is alcohol the other 4 cc is water.
To make a 90% solution, the water would be 10% of the solution.
If 4 cc is 10%, the total is 40 cc.
40 - 10 = 30 cc
30 cubic centimeters needs to be added.

I need help asap please
Answer:
-3 or decreasing by 3
Step-by-step explanation:
To find the average change, you only care about the first and last point which would be (3,17) and (8,2)
the overall change during that time is 2-17=-15 (for the f(x) side )
the overall change during that time is 8-3=5(for the x side)
all we have to do is -15/5=-3
therefore the average rate of change is -3

Earl runs 60 meters in 40 seconds. How many meters does Earl run per second?
Earl runs ___ meters per second.
Answer:
Earl runs 1.5 meters per second
Step-by-step explanation: 60 divided by 40= 1.5
Answer:
1.5 meters/s
Step-by-step explanation:
Since he runs 60 meters in 40 seconds, we can divide 60 by 40 to get how quickly he runs in meters/s. 60/40 = 6/4 = 3/2 = 1.5, so Earl runs 1.5 meters per second.

Y=4x+2
A) Identify the slope (4,-2)
B)Identify the y-intercept:-2
Answer:
4 - slope
2 - y - intercept
Step-by-step explanation:
The equation is in slope-intercept form.
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The '4' is the slope of the equation.
[tex]y=\boxed{m}x+b\\\\y=\boxed{4}x+2[/tex]
The '2' is the y-intercept.
[tex]y=mx+\boxed{b}\\\\y=4x+\boxed{2}[/tex]

How do I solve this equation and find the solutions?
Answer:
x = 10
Step-by-step explanation:
x-sqrt(2x+5) = 5
2x+5 = 25-10x+x^2
x = 10
Hope this helped!
Answer:
x = 5
Step-by-step explanation:
x - 5 = [tex]\sqrt{2x+5}[/tex] ( x > 5)
(x - 5)² = ( [tex]\sqrt{2x+5}[/tex] )²
x² - 10x + 25 = 2x + 5
x² - 12x + 20 = 0
(x - 10)(x - 2) = 0
[tex]x_{1}[/tex] = 10
[tex]x_{2}[/tex] = 2 strange root, does not satisfy the condition x > 5 ( 2 - [tex]\sqrt{2*2+5}[/tex] ≠ 5 )
10 - [tex]\sqrt{2*10+5}[/tex] = 5
10 - 5 = 5
5 = 5

find the value of 5/22×(3/7×(-6/11))and (5/22×3/7)×(-6/7) compare them what do you observe
this is the solution.the diff is the order of the number and the number.
Answer:
After comparing we observe both equations have different answers.
Step-by-step explanation:
Find the value of [tex]\frac{5}{22}\times (\frac{3}{7}\times (-\frac{6}{11}))[/tex] and [tex](\frac{5}{22}\times \frac{3}{7})\times (-\frac{6}{7})[/tex]
Solving [tex]\frac{5}{22}\times (\frac{3}{7}\times (-\frac{6}{11}))[/tex]
[tex]=\frac{5}{22}\times (\frac{3}{7}\times -\frac{6}{11})\\=\frac{5}{22}\times (-\frac{18}{77})\\=\frac{5}{22}\times -\frac{18}{77}\\=\frac{5}{11}\times -\frac{9}{77}\\=-\frac{45}{847}[/tex]
Now solving [tex](\frac{5}{22}\times \frac{3}{7})\times (-\frac{6}{7})[/tex]
[tex]=(\frac{15}{154})\times (-\frac{6}{7})\\=\frac{15}{154}\times -\frac{6}{7}\\=\frac{15}{77}\times -\frac{3}{7}\\=-\frac{45}{539}[/tex]
After comparing we observe both equations have different answers.

Mary sees 40 elephants and 15 baby elephants at the zoo. What is the ratio of elephants to baby elephants?
Answer:
8:3
Step-by-step explanation:
You divide them both by 5.
Answer:
40:15 = 8:3
Step-by-step explanation:
This is the answer because:
1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:
40 ÷ 5 = 8
15 ÷ 5 = 3
8:3
Therefore, the answer is 8:3.
