Cereal is packaged in boxes weighing 24.3 ounces. What is the weight of a
case of 48 boxes of cereal?
Answers
Answer:
1166.4
Step-by-step explanation:
Assuming this is the whole question, you multiply the weight of a single box by the amount in a case to find the weight of a case, hence 24.3*48 =1166.4
1 box of cereal = 24.3
48 boxes of cereal = 24.3 × 48
48 boxes of cereal:-
=> 24.3 × 48
=> 1166.4
Therefore, 48 boxes of cereal weighs 1166.4

Your boss sends you to the hardware store to buy tie down rope. He tells you to buy the best deal. What is the savings per unit between the best deal and worst deal?
A) $50.00
B) $25.00
C) 5 cents
D) 14 cents
Answers
Answer:
D. 14 cents
Step-by-step explanation:
At 10 feet for $7, that is 70 cents for every foot
At 20 feet for $13, that is 65 cents for every foot
At 50 feet for $28, that is 56 cents for every foot
At 100 feet for $57.50, that is 58 cents (rounded) for every foot
The best deal is 50 feet at 56 cents
The worst deal is 10 feet at 70 cents
So we do 70 - 56 = 14
So the answer is the savings per unit between the best deal and worst deal is 14 cents

Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?
A
Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
B
С
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

y= - ⅔x +4
Given:
Simplified as y= mx+ b
2.write the linear equation y= -2x -1 into Ax + By = C.
solution
y = -2x-1
y +(____) = - 2x + (___) - 1
2x + y = -1
Given:
Questions:
1. how did you write the linear equation y = mx + b to the form Ax + By = C?
2. how did you write Ax + By = C?
3. what mathematical concepts or principles did you apply to write each linear equation to standard form?

Answers
1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]
2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x + y = -1
The point-slope form of the equation of a line is y = mx + b
where m represents the slope
b represents the y-intercept
The given equation is:
2x + 3y = 12 (Given)
Subtract 2x from both sides
2x + (-2x) + 3y = 12 + (-2x)
3y = 12 - 2x (Equality property of addition)
3y = -2x + 12 (Commutative property of addition)
Divide both sides by 3
[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)
2) Write the linear y = -2x - 1 into Ax + By = C
y = -2x - 1 (Given)
Add 2x to both sides
y + 2x = -2x + 2x - 1 (Equality property of addition)
y + 2x = -1
2x + y = -1 (Commutative property of addition)

what is the average hourly pay of someone making $45,000per year. Assuming wage growth of 5% a year, how much would he make the second year
Answers
Answer:
When it’s time for annual performance reviews, if you plan on including pay raises, you need to know the simple math behind calculating pay increases correctly. Raises can be based on any number of things including a worker’s piers, standard industry rates, length of time on the job, the amount of work to do, and even whether or not the boss likes the employee or not. There are few, if any, laws that govern how and when increases are granted, so it’s up to you to determine what you’re willing to give.
Answer:
See belowStep-by-step explanation:
Assume the person works 40 hours a week and 52 weeks a year.
The hourly pay would be:
