A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.
Answer the questions below. Do not do any rounding.
(a) How many milliliters of acid are in the resulting mixture?
(b) What percentage of the resulting mixture is acid?
Answers
Answer:
85% acid
Step-by-step explanation:
The amount of acid is 83.75 milliliters
The percentage of the resulting mixture of acid is 67%
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.
This means,
75% of 100 milliliters = 75/100 x 100 = 75 milliliters
35% of 25 milliliters = 35/100 x 25 = 8.75 milliliters
Now,
The amount of acid is (75 + 8.75) = 83.75 milliliters
The percentage of the resulting mixture of acid.
= 83.75 / (100 + 25) x 100
= 83.75/125 x 100
= 67%
Thus,
The amount of acid is 83.75 milliliters
The percentage of the resulting mixture of acid is 67%

Write the equation of the parabola in vertex form.
vertex (0,3), point (1, - 4)
f(x) =
(Simplify your answer.)
Answers
Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.

Drinks cost 1 point 2 5 dollars each, and candy bars cost 1 point 2 5 dollars each.
Drinks cost $1.00 each, and candy bars cost $0.75 each.
Answers
The Drink cost $1.75 each, and candy bars cost $0.75 each.
let
The price of a drink = x
The price of a candy bar = y
Bart total purchase
2x + 2y = 5Claudia total purchase
x + 4y = 4.75The cost of each can be calculated by combining the equations. Therefore,
2x + 2y = 5
x + 4y = 4.75
x = 4.75 - 4y
2(4.75 - 4y) + 2y = 5
9.5 - 8y + 2y = 5
9.5 - 6y = 5
-6y = -4.5
y = -4.5/-6
y = 0.75
2(0.75) + 2x = 5
1.5 + 2x = 5
2x = 5 - 1.5
2x = 3.5
x = 3.5/2
x = 1.75
Cost of a drink = $1.75
Cost of a candy bars = $0.75

Denzel identified (3,2) as a point on the line y-2 = 2/3 (x+ 3). What is the error Denzel made?

Hi there!

Here’s why:
⸻⸻⸻⸻
[tex]\text{General Point-Slope Form is:}\\\\y - y_1 = m(x-x_1)\\\rule{150}{0.5}\\\\(x_1,y_1) -\text{A point that is given.}\\\\m -\text{Slope}[/tex]

Denzel incorrectly identified the x-value of the given point. The value '-3' is actually indicated in the equation. If you plug in '-3' into the equation, you would get '-(-3)', which simplifies to '+3'.⸻⸻⸻⸻
[tex]y-2 = \frac{2}{3} (x-x_1)\rightarrow y-2 = \frac{2}{3} (x-(-3))\rightarrow y-2=\frac{2}{3} (x+3)[/tex]

The point in the equation should be: (-3, 2).
»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.
The correct points of the line will be (-3,2).
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the point (3,2) is on the line y-2 = 2/3(x+ 3). Satisfy the equation with the given point and check.
y-2 = 2/3(x+ 3)
2-2 = (2/3)(3 + 3)
0 = 4
To make left hand side and right hand side equal the value of x coordinate should be -3.
y-2 = 2/3(x+ 3)
2-2 = (2/3)(3 + 3)
0 = 0
Therefore, the correct points of the line will be (-3,2).

Write an equation in slope-intercept form for the line described. Write the slope and y-intercept as fractions, if necessary. passes through (6, 2), parallel to y = -}x+1
Answers
The slope of your answer will be whatever number is supposed to be in front of the x (assuming you hit the close brace on accident the same time you hit the minus sign, I’m gonna assume you meant to put -x+1) making the slope of your answer -1.
So you have y=-x+b
To find b, plug in (6,2)
2 = -(6) + b
8 = b
So, your answer would be
y = -x + 8
Otherwise, whatever is suppose be in front of the x,
y = -mx + (2+6m)
