Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 2 scoops of powdered drink mix with a half a gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 8 scoops with 2 gallons of water to get 4 pitchers. How can you use the concept of proportion to decide whether the student is correct?
Answer:
2 scoops per pitcher,
Step-by-step explanation:
2 (per pitcher) * 4(pitchers) = 8
2 scoops makes 1 pitcher and she's using 8 scoops so that would give us 4 pitchers.

what is the linear equation of (0.5,10) and -4.5,-10
Answer:
The linear equation containing the points (0.5, 10) and (-4.5, -10) will be:
[tex]y=4x+8[/tex]Please check the attached graph also.
Step-by-step explanation:
Given the points
(0.5, 10)(-4.5, -10)Finding the slope between (0.5, 10) and (-4.5, -10)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0.5,\:10\right),\:\left(x_2,\:y_2\right)=\left(-4.5,\:-10\right)[/tex]
[tex]m=\frac{-10-10}{-4.5-0.5}[/tex]
Refine
[tex]m=4[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointsubstituting the values m = 4 and the point (0.5, 10) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 10 = 4(x-0.5)[/tex]
Add 10 to both sides
[tex]y-10+10=4\left(x-0.5\right)+10[/tex]
Simplify
[tex]y=4x+8[/tex]
Therefore, the linear equation containing the points (0.5, 10) and (-4.5, -10) will be:
[tex]y=4x+8[/tex]Please check the attached graph also.

Which multiplication expression can be used to find 3/5 divided by 7/10
Answer:
[tex]\frac{3}{5}[/tex] x [tex]\frac{10}{7}[/tex]
Step-by-step explanation:
For each expression, write an equivalent expression by applying the distributive
property.
2. (x + 4)(2x - 1)
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
(x + 2) (x + 9)
(x + 4) (2x - 1)
(x - 5)²
Now,
Applying the distributive property.
1)
(x + 2) (x + 9)
x² + 9x + 2x + 18
x² + 11x + 18
2)
(x + 4) (2x - 1)
2x² - x + 8x - 4
Combining the like terms.
2x² + 7x - 4
3)
(x - 5)²
(x - 5) (x - 5)
x² - 5x - 5x + 25
x² - 10x + 25
Thus,
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25

Geometry help please. What is the value of v?
Answer:
v=15
Step-by-step explanation:
31+4v+44=9v
Answer:
v = 15
Step-by-step explanation:
By exterior angle theorem:
9v° = 31° + (4v + 44)°
9v° = (4v + 44 + 31)°
9v = 4v + 75
9v - 4v = 75
5v = 75
v = 75/5
v = 15

Two numbers differ by 5. The sum of their squares is 193. Find the numbers.
Answer:
Let one number be x and the other be (x-5)
Step-by-step explanation:
x^2+(x-5)^2=193
x^2+x^2-10x+25=193
2x^2-10x+25=193
Subtract 193 from both sides of the equation.
2x^2-10x-168=0
x=12 or x=-7

In a normally distributed data set with a mean of 24 and a standard deviation of 4.2, what percentage of the data would be between 19.8 and 28.2 and why
Answer:
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 24
Standard deviation = 4.2
What percentage of the data would be between 19.8 and 28.2
19.8 = 24 - 4.2
28.2 = 24 + 4.2
So within one standard deviation of the mean
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
