Answer:
176 of 12% vinegar
44 of 7% vinegar
Step-by-step explanation:
Percentage vinegar required = 11%
Volume = 220 mL
First brand % = 7%
Second brand % = 12%
Let p = volume of 12% vinegar material
Mixture :
0.12p + 0.07(220 - p) = 220 * 0.11
0.12p + 15.4 - 0.07p = 24.2
0.05p = 8.8
p = 8.8 / 0.05
p = 176
176 of 12% vinegar and
220 - 176 = 44
44 of 7% vinegar

Write the equation of a line that is perpendicular to the given line and that passes through the
given point.
y-2= 7/3 (x + 5);(-4,9)
Oy-9=-3/7(x-4)
Oy-9= 3/7(x-4)
Oy- 9= -3/7(x+4)
Oy- 9= -3/7(x+4)
Answer:
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
Step-by-step explanation:
Slopes are negative reciprocals when two lines are perpendicular
[tex]m= - \frac {3}{7}[/tex]
Equation of straight line in point-slope form is given as
[tex]y-y_1=m(x-x_2)[/tex]
Here [tex](x_1, y_1)= (-4, 9)[/tex]
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, 9).
And, The perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
Now,
Since, The equation of line passes through the point (- 4, 9).
So, We need to find the slope of the line.
Since, The product of the slope of perpendicular line is - 1.
Hence, Slope of the perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
m = dy/dx = 7/3
m = 7/3
Thus, The equation of line with slope - 3/7 is,
⇒ y - 9 = - 3/7 (x - (-4))
⇒ y - 9 = - 3/7 (x + 4)
⇒ y - 9 = - 3/7x - 12/7
⇒ y = - 3/7x + 9 - 12/7
⇒ y = - 3/7x + 51/7
Therefore, The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7

Help pls and thank:)
Answer:
y=-3x+2
Step-by-step explanation:
Slope-intercept form is given by the equation y=mx+b, where m is defined as the slope and b is defined as the y-intercept (the value on the y-axis that the line crosses). First we can determine the slope by using the slope formula.
m=(y2-y1)/(x2-x1), given two points (x1, y1) and (x2, y2). Keep in mind you can choose which point is (x1,y1) and which is (x2,y2) as long as you are consistent.
Plugging in for (-1,5) and (1,-1), you will get:
m=(-1-5)/(1-(-1))=-6/2=-3
Next, we need to find the y-intercept. For this problem, you can determine it is 2 by looking at the graph of the line. We now have both components to create the slope-intercept form.
m=-3, b=2
y=-3x+2

1. The product of 4, and a number decreased by 7, .is 100. Find the number
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32

How do you divide fraction (in the simplest form)
Answer:
1/3 divided by 5/4
So we divide both the top by 3 and the bottom by 3 and so our final answer would be 4 over 7. So that's our simplified fraction
-------------
Invert and multiply:
Take the reciprocal of the divisor and multiply the dividend. The top and bottom are being multiplied by the same number. Since that number is the reciprocal of the bottom part, the bottom becomes one.
Find the biggest common number:
It could be said to be a "more correct" method. This is the correct way since, you can’t divide apples by oranges in the same way as you can’t divide fifths by fourths.
Answer:
Step-by-step explanation:
You find the biggest common number you can divide the numerator and denominator.
For example, we have our answer is 8/12 so you can divide it into 1,2, and 4. 8/12 divide by 1/1 = 8/12. 8/12 / 2/2 = 4/6. 8/12 / 4/4 = 2/3.
So the answer is 2/3.

Answer:
20, 16, 6 can be side lengths
7, 7, 3 can be side lengths
3, 7, 14 cannot be side lengths
9.9, 25.0, 15.6 can be side lengths
Step-by-step explanation:
The rule for determining if three length can make up a triangle is to consider the length of any of the two and compare with the third length to check if it's greater.
mathematically, assume that a, b, c are three lengths. they will only form a triangle if these three conditions are true.
a + b > c;
b + c > a;
a + c > b;
That is the reason the only 3,7,14 cannot form a triangle because 3 + 4 < 14
