How much alcohol must a pharmacist add to 10 cm^3 of an 8% alcohol solution to strengthen it to an 80% solution? PLS ANSWER URGENT THANKS
Answers
The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.
What is alcohol ?Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.
Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:
[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]
Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.
The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).
Now we can solve for x:
[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]
[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]
[tex]0.2x = 7.2 cm^3[/tex]
[tex]x = 36 cm^3[/tex]
Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

A student is buying thank you cards. Each than you card cost $2. The equation t = 2c represents the total cost, t, this student will spend to buy c cards. Which variable is the independent variable in the equation? Which is the dependent variable? Explain how you know.
Answers
Answer:
t is dependent and c is independent because if c increases so will t
The dependent variable, on the other hand, is the variable that is being measured or observed, and it is typically plotted on the y-axis of a graph. In this equation, "t" represents the total cost of the thank you cards, which is something that depends on the number of cards being purchased. The cost is not something that the student can control directly, but rather it is determined by the number of cards being purchased.
Therefore, in the equation t = 2c, "c" is the independent variable because it is being manipulated by the student, and "t" is the dependent variable because it depends on the value of "c".

[tex]\textsf{We are given the \underline{Perimeter}, and the \underline{Length}.}[/tex]

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.
q and t are alternate interior
r and k are alternate interior
W is 79
The mistake he made is equating an alternate interior angle to an alternate exterior angle
1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.
Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.
2. check the picture for translation of the angles
3. 8 angles are created, 4 alternate interior and 4 alternate exterior
Angles 6,4 and 2 are congruent to 8

A dinner plate has a circumference of 125.6 cm. What is the area of the dinner plate? (Use 3.14 for π)
A. 251.2 cm2
B. 1,256 cm2
C. 62.8 cm2
D. 2,512 cm2
Answers
area = 3.14 r^2
circumference = d * 3.14
To solve:
First we need to work backwards from the circumference to find the diameter- we start with 125.6 = 3.14 * d. We then divide by 3.14 to get 40 = d. Divide by 2 to get the radius and we get 20 cm. Then, we plug the radius into the area formula, getting us 3.14 * 20^2. 20^2 = 400, so we get 3.14 * 400. 3.14 * 400 = 1256, so the area is 1256 cm2.

Grade8
Answers
Answer:
a: -4p² + 5q² - 4pq - 2
b: -3x + 3y
Step-by-step explanation:
When we combine like terms, we get:
(-6p²+8q² - 2pq- 5) + ( 2p² -3q² -2pq+3) = -4p² + 5q² - 4pq - 2
Therefore, the simplified expression is -4p² + 5q² - 4pq - 2.
Next:
(5x+6y)+ (-8x -3y) = 5x - 8x + 6y - 3y
Combining like terms gives us:
5x - 8x + 6y - 3y = -3x + 3y
Therefore, the simplified expression is -3x + 3y.

Gianna and her family went for a drive. They traveled 175 miles in 3 hours. What was their average speed?
Would you write an inequality or an equation?
Answers
To find the average speed, we divide the total distance traveled by the time taken:
Average speed = Total distance ÷ Time taken
Therefore, Gianna and her family's average speed is:
Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)
We use an equation to solve this problem.
Equation: Average speed = Total distance ÷ Time taken
Where:
Total distance = 175 miles
Time taken = 3 hours
Substituting these values into the equation, we get:
Average speed = 175 miles ÷ 3 hours
Therefore, the answer is an equation:
Average speed = 175 miles ÷ 3 hours

The singh family orderd a large pizza with a diameter of 20 inches for dinner. If one of the members ate one-eighth of the pizza, how many square inches of pizza are remaining? (use 3.14 for pi)
Answers
Answer:
275.5 square inches of pizza remaining
Step-by-step explanation:
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.
The area of the entire pizza is:
A = πr^2 = 3.14 x 10^2 = 314 square inches.
If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.
The remaining area of the pizza is:
(7/8) x 314 = 275.5 square inches.
Therefore, there are 275.5 square inches of pizza remaining.
