A local sporting goods store is planning to hire up to 24 temporary employees for its annual Black Friday Sale. Experienced workers (x) will be paid $20 per hour and produce 1.5 times the profit that an inexperienced worker produces. Inexperienced workers (y) get hired at $15 per hour. The store can pay up to $400 per hour for the temporary employees. How many of each type of worker can be hired to maximize profit?
Answer:
8 experienced workers and 16 inexperienced workers
Step-by-step explanation:
Let x represent the number of experienced workers, y represent the number of inexperienced workers.
The store can hire up to 24 temporary employees, hence:
x + y ≤ 24
The store can pay up to $400 per hour, hence:
20x + 15y ≤ 400
Also, x, y > 0
The solution to the above problem is at (8, 16). Hence x = 8 and y = 16.
The profit of an experienced worker is 1.5 times the profit that an inexperienced worker. hence:
Profit = 1.5x + y
Profit = 1.5(8) + 16
Profit = 12 + 16 = 28

If AM = MB, then AM + 5 = MB + 5.
which property
Answer:
Addition Property of Equality
Step-by-step explanation:
If A = B, then A + C = B + C
The statement is illustrating the Addition Property of Equality.
In the statement, A is AM, B is MB, and C is 5. Hope this helps!
The property of the required statement is addition Property of Equality.
It is required to find the property of the required statement.
What is a statement?A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.
Given:
Addition Property of Equality:
In an equation, the additive property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.
If A = B, then A + C = B + C
∴c=c
Therefore, the property of the required statement is addition Property of Equality.

Answer:
x = 8
Step-by-step explanation:
The perimeter of a body is the sum of all its sides.
Perimeter of the triangle;
hypothenuse + opposite + adjacent = x+6 + x + 3 + x + 9 = 3x + 18
Perimeter of the rectangle = x+1 + x + 4 + x + 1 + x + 4 = 4x + 10
Now,
Since their perimeter is equal;
3x + 18 = 4x + 10
3x - 4x = 10 - 18
-x = -8
x = 8
A mechanic buys 2 barrels of oil. If there are 63 gallons in every barrel and approximately 3.785 liters for every gallon, approximately how many liters of oil did the mechanic buy?
Answer:
476.91 Liters
Step-by-step explanation:
Lets start by figuring the liters per gallon amount. 63 times 3.785 equals 238.455. Since we have 2 barrels, we need to multiply this by 2 in order to get a grand total of 476.91 liters of oil.

Kevin rented a truck for one day. there was a base fee of $17.99, and there was an additional charge of 95 cents for each mile driven. Kevin had to pay $157.64 when he returned the truck. for how manny miles did he drive the truck?
Answer:
Step-by-step explanation:
Base fee = $17.99
Additional charge = $0.95 for each mile driven
If Kevin paid $157.64 when he returned the truck and we want to find out how many miles he drove the truck, step 1 would be to subtract the base fee.
157.65 - 17.99 = 139.65
This means that the remaining $139.65 is how much he paid for the miles he drove.
Since we know each mile costs $0.95.
Simply divide $139.65 by $0.95 to work out how many miles he drove.
Miles driven = 139.65 / 0.95 = ?

Donna has 6 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same
distance to cool down. If she runs at a speed of 10 mph and walks back at a speed of 2 mph, how long should she plan to spend walking back?
Answer:
Avg speed of the round trip = 2*10*2/(10+2) = 10/3 mi/hr
D = r*t = (10/3)*6 = 20 miles
--> 10 miles each way
--> 5 hours walking back.
She'll get bored doing that.
Step-by-step explanation:
A function that changes in the same way all the time is?
Answer:
A function that changes the same way can be a linear function.
y = a*x + b.
Where the rate of change (this is, how much changes y when x increases or decreases) is defined by the coefficient a, that is constant.
for example, suppose that when x = x0, we have y = y0
y0 = a*x0 + b.
Now x0 increases by one unit, to (x0 + 1)
y = a*(x0 + 1) + b = (a*x0 + b) + a = y0 + a.
Then if x increases (or decreases) 1 unit, y increases (or decreases) a units.
Now, we can define the rate of change of a function as it's derivate with respect to some variable.
In this case, if we derive with respect to x, we have:
y' = a
Then the rate of change is constant.
Translations can be written using ordered pair notation

It says solve each triangle so what parts am I solving? Do I solve all parts or if there’s 2 angles and 1 side, I look for the other angle?
Step-by-step explanation:
Solving a triangle means finding all unknown sides and angles.
For example, in #9, the third angle is 180° − 81° − 59° = 40°.
Using law of sines, the other two sides are:
a / sin 59° = 15 / sin 40°
a = 20.0
b / sin 81° = 15 / sin 40°
b = 23.0
