You have 10 pounds of egg whites. You need 6 Oz to make one serving of consommé. How many servings can you make?
Here, we want to solve for the number of servings 10 pounds of egg whites can make
Number of servings 10 pounds of egg whites can make is approximately 27 servings
1 pound = 16 ounce
10 pounds = 160 ounce
Quantity of egg whites available = 10 pounds
Quantity of egg whites per serving = 6 oz
Number of servings 10 pounds can make = Quantity of egg whites available / Quantity of egg whites per serving
Recall,
10 pounds = 160 oz
= 160 oz / 6 oz
= 26.67
Approximately,
27 servings

Answer: 8
Step-by-step explanation:
Help thank you ………….
Answer:
The answer is option 1
Step-by-step explanation:
For the linear inequality on the top line of the system, it's saying that the y-value must be greater than or equal to 1. This is verified by the graph because all y-values that fit the criteria of the linear inequality are shaded. The graph is also showing for the dotted line that the area is shading all points where, if you subtract an x-value from a y-value, the difference will always be greater than 0. Note that this does not apply for points ON the line, as it cannot be equal to 0. This matches with the linear inequality on the bottom line of option 1.

An art museum has a pentagon-shaped room. When drawn to scale on a coordinate grid, the corners of the room are points A(15,21);
B(8,21); C(8,10); D(13,8); E(19,14.5), shown in feet. The walls are 11 feet high.
The museum is going to paint four of the walls: AB, BC DE, and AE. Assume one gallon of paint is enough to cover 147
square feet
How many gallons of paint should the museum purchase? Enter your answer as a whole number.

Answer:
3 gallons
Step-by-step explanation:
When calculations are repetitive, I find it convenient to use a spreadsheet to do them. The formulas used are ...
distance between points (x1, y1) and (x2, y2) = √((x2-x1)² +(y2-y1)²)
length of walls to be painted: AB +BC +DE +EA = 34.5 ft
area of walls to be painted: (length)(11 ft) = 379.3 ft²
gallons of paint needed: area/(147 ft²/gallon) = 2.6 gal
About 3 gallons of paint are needed to paint 4 walls of the room.

Triangle ABC is similar to triangle DEF with a ratio of 3/5 If the difference of their
perimeters is 40 inches, find the perimeter of each triangle.
9514 1404 393
Answer:
ΔABC -- 60 inchesΔDEF -- 100 inchesStep-by-step explanation:
If P is the perimeter of the larger triangle, then 3/5P will be the perimeter of the smaller one. The difference in perimeters is ...
P -3/5P = 40 in
2/5P = 40 in
P = (5/2)(40 in) = 100 in
3/5P = 3/5(100 in) = 60 in
The smaller triangle perimeter is 60 in; the larger is 100 in.

When both quantities in a rate are fractions, what strategy
do you use to write the rate as a unit rate?
When both quantities in a rate are fractions, the strategy to write the rate as a unit rate is to divide both the numerator and denominator of the rate by their greatest common factor (GCF) to simplify the fraction.
To write the rate as a unit rate:
1. Identify the rate, which is a fraction with a numerator and a denominator.
2. Find the greatest common factor (GCF) of the numerator and denominator.
3. Divide both the numerator and denominator by the GCF to simplify the fraction.
4. The resulting simplified fraction is the unit rate.
For example, if the rate is 3/6, the GCF of 3 and 6 is 3. Divide both the numerator and denominator by 3:
3/6 ÷ 3/3 = 1/2
So, the unit rate of 3/6 is 1/2.
By converting the rate to a unit rate, we make it easier to compare the rate for a single unit of one quantity to a single unit of the other quantity, making it more convenient for comparison and analysis.

Ok I don’t know how they got 3y-24
Answer:
y = -5/3x + 3
Step-by-step explanation:
First lets turn the equation from standard form to slope intercept form.
3x - 5y = 1
~Subtract 3x to both sides
-5y = 1 - 3x
~Divide -5 to everything
y = -1/5 + 3/5x
~Reorder
y = 3/5x - 1/5
Now that we have the equation in slope intercept form, we can find the new equation. A perpendicular line will have the opposite reciprocal of the original slope.
3/5x -> -5/3x
Now that we have the slope, we can use the given point to find the y-intercept.
y = -5/3x + b
8 = -5/3(-3) + b
8 = 5 + b
3 = b
Put all the information we solved for into a final equation.
y = -5/3x + 3

The option (2) As x → ∞, y → ∞, and option (6) As x → –∞, y → –∞ are correct if the function f(x) = (x - 2)(x + 2)/(x + 1).
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function shown in the picture.
f(x) = (x - 2)(x + 2)/(x + 1)
The above function is a fractional function:
The denominator of the function cannot be zero:
x + 1 ≠ 0
x ≠ -1
From the graph of a function:
If x → ∞, y → ∞
If x → –∞, y → –∞
Thus, the option (2) As x → ∞, y → ∞, and option (6) As x → –∞, y → –∞ are correct if the function f(x) = (x - 2)(x + 2)/(x + 1).

(65x - 12) angle a
(43x+10) angle b
it’s a vertical angle I just don’t understand.
Answer:
x = 1
Step-by-step explanation:
Vertical angles are opposite angles formed by two lines.
Both the angles are equivalent
65x - 12 = 43x + 10
Subtract 43x from both sides
22x - 12 = 10
add 12 from both sides
22x = 22
Divide each side by 22
x = 22/22
x = 1

Greyson will get a discount on his health insurance if he participates in their weekly step-challenge program and logs 50,000 steps a week. If his monitor calculates each step to be 2 feet, how many miles is he supposed to walk each week?
Greyson will need to walk "18.94 miles" each week. A complete solution is provided below.
