Answer: Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 30 milliliters
Step-by-step explanation:
Given: Total solution required = 130 milliliters
Let x = Amount of 35% solution (in milliliters).
Then, Amount of 87% solution required = 130 - x
As per given,
Concentration = 0.35x +0.87(130-x)=0.47(130)
Hence, Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 130-100 milliliters =30 milliliters
<h3>I'll teach you how to solve 2x+3>5</h3>
-------------------------------------------
2x+3>5
Subtract 3 from both sides:
2x+3-3> 5-3
Simplify:
2x > 2
Divide both sides by two:
2x/2 > 2/2
Simplify:
x >1
Your Answer Is x>1

Answer:
the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15
Step-by-step explanation:
the mode is 5 and 2 because they both occur the most often
The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5
the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25
the range is 15 because the range is the diff between the highest and lowest value
It will go through (0,0) because it is direct variation
The main formula is integr U^p du = (1/1+p)U^p+1
let be U=<span>(25 - 16x^2)^-1/2,
</span>1/sqrt(25 - 16x^2) = (25 - 16x^2)^-1/2
du= -1/2)(-32x)(25 - 16x^2)^-1/2dx
integ du/-1/2)(-32x)= integ(25 - 16x^2)^-1/2dx
nteg du/16x)=1/16xu+c=integ(25 - 16x^2)^-1/2dx
finally
integ 1 / sqrt(25 - 16x^2) dx = 1/16xu+c= (1/16x)(<span>(25 - 16x^2)^-1/2) +c
