3/4 w=6 solve for w
Bc.
Answers
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.

Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?
What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20

1.Let k be a positive real number. The line x + y = k and the circle x^2 + y^2 = k are drawn. Find k so that the line is tangent to the circle.
2.Let A = (6,2), and let B be the reflection of A over the line y = 1/2x + 5. Find the coordinates of B
Answers
2. The line y = 1/2x + 5 has slope 1/2, so the line perpendicular to it that passes through A = (6, 2) has slope -2. The equation of this line is y - 2 = -2(x - 6), which simplifies to y = -2x + 14. To find the reflection B of A over the line y = 1/2x + 5, we need to find the intersection of the line y = -2x + 14 and the perpendicular bisector of the segment AB. The midpoint of AB is ((6 + x)/2, (2 + y)/2), and the slope of AB is (y - 2)/(x - 6). Therefore, the slope of the perpendicular bisector of AB is -1/(y - 2)/(x - 6), which simplifies to (6 - x)/(y - 2). The equation of the perpendicular bisector of AB is y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2. Solving the system of equations y = -2x + 14 and y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2, we get B = (5, 8). Therefore, the coordinates of B are (5, 8).

4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?
Answers
To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.
Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.
The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.
The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.
The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:
0.32 + 0.02x = (4/100) * (4 + x)
Simplifying the equation:
0.32 + 0.02x = 0.04(4 + x)
0.32 + 0.02x = 0.16 + 0.04x
0.02x - 0.04x = 0.16 - 0.32
-0.02x = -0.16
Dividing both sides by -0.02:
x = (-0.16) / (-0.02)
x = 8
Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
To solve this problem, we can use the following equation:
4+x4×8+x×2=4
This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.
To find x, we can simplify and solve for x:
4+x32+2x=4
32+2x=16+4x
16=2x
x=8
Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

Apricots are less expensive by $2.24 per pound.
Step-by-step explanation:
The cost of 2 pound of almonds for = $21.98
The cost of 1 pound of almonds =
= $10.99
The cost of 3 pounds dried apricots for = $26.25

Find the equation of the line perpendicular to x+2y=14 and passing through (6,9)
Answers
Answer:
\(y= 2x - 3\)
Step-by-step explanation:
rearrange equation into slope-intercept form
isolate y by subtracting x from both sides
\(2y=-x+14\)
divide two from both sides
\(y= -\frac{1}{2}x+7\)
here, we can note that the slope is -1/2, which to be perpendicular means it needs the negative inverse of slope
in other words, flip the fraction and take the negative of it, which gives m = 2
therefore plugging the given coordinates (6,9) and slope m = 2 into
\(y-y_{1} = m(x-x_{1} )\)
therefore, we get
\(y-9=2}(x-6)\)
distribute 2
\(y-9 = 2x - 12\)
add 9 to both sides
\(y= 2x -3\)
Answer:
y = 2x-3
Step-by-step explanation:
find the slope intercept first by isolation the y in the first equation
then because its asking for the perpendicular equation you will flip the x in the slope intercept equation.
now youll want to plug in (6,9) into y = 2x + a
and you will get -3
then youll have your answer
The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.
