The load each should get to maximize the profit is $67,500, $78,700 and $90,000
What Is Profit?
In accounting, a profit is an income that is given to the owner throughout a successful market producing process. Profitability, which is the owner's primary interest in the income-formation process of market production, is measured by profit. There are various profit metrics that are frequently used.
Let x represent the total number of laptops and y represent the total number of desktop computers.
A laptop computer occupies 2 cubic feet, hence x laptops each use 2x cubic feet. Desktop computers take up 5 cubic feet of space, hence 5y cubic feet of room is required for 5y desktop computers.
They require 2x + 5y cubic feet in total.
Since the delivery truck's maximum capacity is 800 cubic feet,
2x + 5y <= 800.
They must load at least 300 laptops because of the demand,
hence, x >= 300
They make $225 on each laptop, which translates to $225 times as many computers. They make a profit of $280 on each desktop computer, or $280y on y desktops.
Total profit is:
P=$(225x + 280y)
Draw the inequality system (see attached diagram)
2x + 5y <= 800.
x >= 300
One of the common region's three vertices will have the most profit:
P(300,0) = 225(300) + 280(0) = $67,500
P(300,40) = 225(300) + 280(40) = $78,700
P(400,0) = 225(400) + 280(0) = $90,000
Hence, each should load $67,500, $78,700 and $90,000 on the truck to maximize profit

pls help asap Noor’s family is meeting her grandparents at a restaurant. The restaurant is 24.5 miles from Noor’s house. This is 65.5% of the distance from Noor’s house to her grandparents’ house. What is the distance between the two houses? Round your answer to the nearest tenth of a mile.
The distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles using the estimation concept.
As per the question statement, Noor’s family is meeting her grandparents at a restaurant and the restaurant is 24.5 miles from Noor’s house but this is 65.5% of the distance from Noor’s house to her grandparents’ house.
We are supposed to find the distance between Noor's house and her grandparent's house. We will use the concept of estimation.
Distance between Noor's house and restaurant = 24.5 miles
Let distance between Noor's house and her grandparent's house be "x" miles.
So the distance between grandparent's house and restaurant = x - 24.5
Now it is given that 24.5 miles is 65.5% of the distance from Noor’s house to her grandparents’ house.
So, 65.5% of x = 24.5
(65.5*x)/100 = 24.5
65.5*x = 2450
x = 2450 / 65.5
x = 37.40 miles
If rounded off to the nearest tenth mile, we get
x = 40 miles.
So, the distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles.

in the first week of July, a record 1,020 people went to the local swimming pool. In the second week, 100 fewer
people went to the pool than in the first week. In the third week, 135 more people went to the pool than in the second week.
In the fourth week, 137 fewer people went to the pool than in the third week. What is the percent decrease in the number of
people who went to the pool over these four weeks?
With the concepts of percentages and calculations, the percent decrease in the number of people who went to the pool over these four weeks is 10%
What is the way to solve percentages?Take the base as 100 and convert the percentage to numbers and then proceed with the same.
Now, the initial number of people in the local swimming pool is 1020, after which 100 fewer went, hence 920 people
Now, 135 people more people need to be added, thus 1055 people.
Now, 137 fewer people went, so 918 people went to the pool in the four weeks.
Therefore percent decrease = Difference/No. of people in the first week * 100
Thus, the percent decrease = 102/1020*100=10%
Hence 10% of people went less in the fourth week as compared to the first week.

Terry bought 2 shirts for $14 each, 2 pair of socks for $2.99 a pair, and a pair of slacksfor $25.00. The sales tax rate is 6.5%. How much did he pay? (Enter the dollar amountonly. Round to the nearest cent.)
Answer:
Explanation:
Terry bought 2 shirts for $14 each.
That is $28 on shirts
2 pair of socks for $2.99
That is $5.98 on socks
A pair of slacks for $25
The sales tax rate is 6.5% or 6.5/100 or 0.065
We want to know how much he paid.
Adding all the items he bought together, we have:
$28 + $5.98 + $25
= $58.98
Next, we apply the sales tax rate.
Take 6.5% of $58.98
This is: $58.98 * 0.065
= $3.83
Finally, add the sales tax with the amount we got
$58.98 + $3.83
= $62.81
He paid $62.81 in total
A train of length 150 metres entered a straight tunnel of length s metres. It took the entire crossing of the tunnel in a time of 15 seconds. Find the length of the tunnel if the train moves with uniform velocity equals 90 km./hr
The tunnel measures 225 meters in length.
Uniform velocity: What is it?
Velocity is the measure of how quickly an object's position changes over time and in relation to a frame of reference. A body moves across space with uniform velocity when it does so with an equal displacement per unit of time.
Velocity is equal to the product of distance and time.
It measures in m/s.
In response to the query, we are provided with the-
150m is the length of the train.
s m is the tunnel's length.
90 km/hr is the train's speed.
= 90 × 5/18 m/sec
= 25m/sec
Total distance equals (train length plus tunnel length).
[tex]Speed = \frac{Distance}{Time}[/tex]
⇒ 25 = (150 + s) / 15
⇒ 25 × 15 = 150 +s
⇒ 375 = 150 + s
⇒ 375 - 150 = s
⇒ s = 225
⇒ s = 225m
Hence, the length of the tunnel is 225 m.

Mia made a mistake in Step 3. She simplified the exponents 16 and -8 incorrectly. She should have subtracted them.
Which properties of exponents are used in this problem?When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, as follows:
3^0 x 3^(16) = 3^(0 + 16) = 3^16.
Hence the Step 1 is correct.
For the power of power rule, we keep the base and multiply the exponents, hence:
(3^(-4))² = 3^(-4 x 2) = 3^(-8).
Hence the Step 2 is correct.
When two terms with the same base and different exponents are divided, we keep the base and subtract the exponents, as follows:
3^16/(3^(-8)) = 3^(16 - (-8)) = 3^(16 + 8) = 24.
Which is Mia's mistake, as she did not subtract the exponents.

Examine graphs A and B. What do you notice about the difference between the Y axis for the good graph A and the Poot graph B? How is a break shown on the Y axis of graph A
Answer:
The well-desgined graph has an appropriate scale for the y-axis. By appropriate we mean that the scale is such that all points on the graph can be discerned easily. In other words, the scale is not too wide or too narrow.
For graph A, the scale is such that the data points are at such a distance from each other that their values can be easily read off. On the other hand, for graph B, there isn't enough vertical distance between the data points for them to be easily read.

square feet. What was the width of the plywood?
The width of the plywood = 23/8 ft
The two rectangular pieces of plywood had equal widths.
The length of first rectangular piece = 6 ft
The length of second rectangular piece = 5 1/2 ft = 11/2 ft
The two pieces are joined to make a single rectangular stage.
Then the total length of the stage = 6 + 11/2 = 23/2 ft
Now area of the rectangular stage = 66 1/8 = 529/8 square feet.
⇒ length x width = 529/8
⇒ 23/2 x width = 529/8
⇒ width = 529/8 x 2/23 = 23/4 ft
Let 'x' be the width of a rectangular plywood.
Then 2x = width of the stage
