A store is offering a $30 mail in rebate on all color printers. Luis is looking at different color printers that range in price from $175 to $260. How much can he expect to spend after the rebate?
subtract 30 from both prices shown
175 -30 = 145
260 -30 = 230
he will spend between 145 and 230 after the rebate
After applying the $30 mail-in rebate, Luis can expect to spend anywhere from $145 to $230 on a color printer.
Explanation:The problem is asking to find out how much Luis will spend on a color printer after applying a $30 mail-in rebate. Given that the printers range in price from $175 to $260, we subtract the rebate from each of these prices to get the range Luis might expect to pay.
To calculate the minimum price, we take the lowest price of $175 and subtract the mail-in rebate: $175 - $30 = $145.
And to calculate the maximum price, we take the highest price of $260 and subtract the rebate: $260 - $30 = $230.
So, after applying the $30 mail-in rebate, Luis can expect to spend anywhere from $145 to $230 on a color printer.

A man standing 13 feet from the base of a lamppost casts a shadow 5 feet long. if the man is 6 feet tall and walks away from the lamppost at a speed of 450 feet per minute, at what rate, in feet per minute, will the length of his shadow be changing?
The length of his shadow be changing 2250/13.
What is proportion?A proportion is an equation in which two ratios are set equal to each other.
Given:
height of men = 6 feet
Shadow height= 5 feet
speed of men= 452 feet/ min
So, Lampost's height = 6 x (5 +13)/ 5 =108/5
Now, using the proportion
L/ (L + 13 + 450 t)= 30/108
108 L= 30 L + 390 + 13500t
78 L = 390 + 13500t
L= 5 + 2250/13 t
hence, length of his shadow be changing 2250/13.

The previous task asked you to select the rectangle that did not represent an enlargement of the given rectangle. explain how you determined which rectangle was not an enlargement.
The ratio table should show dimensions that are proportional to the original rectangle. That is, the dimensions of the other rectangles should be multiplied by a scale factor for the enlargement. I checked each dimension to see if it was a multiple of the original rectangle.
Final answer:
To determine if a rectangle is an enlargement, compare the corresponding sides of the rectangles.
Explanation:
To determine which rectangle is not an enlargement of the given rectangle, you should compare their corresponding sides. An enlargement is a proportional increase in the dimensions of the original shape. If the corresponding sides of the two rectangles are not scaled by the same factor, then it is not an enlargement.
Identify the dimensions of the given rectangle.Compare the corresponding sides of each rectangle.If the corresponding sides are not scaled by the same factor, then the rectangle is not an enlargement.The average height of a female draft is 4.6 meters. Was her height in centimeters.
Final answer:
To convert the average height of a female giraffe from meters to centimeters, multiply 4.6 meters by 100, resulting in 460 centimeters.
Explanation:
To convert the average height of a female giraffe from meters to centimeters, we need to use the conversion factor where 1 meter is equivalent to 100 centimeters. If the average height is 4.6 meters, then we need to multiply this value by 100 to find the height in centimeters
Step-by-step calculation
This conversion process, from meters to centimeters, simplifies the representation of the average height of a female giraffe. Utilizing the conversion factor, where 1 meter equals 100 centimeters, the calculated result of 460 centimeters provides a more practical and commonly used metric. Such conversions are valuable for ensuring consistency in measurement units and facilitating communication across different contexts, enhancing our understanding of the physical dimensions of giraffes in a more accessible manner.

Simplify the expression. (–9m + 12) –6m + 12 –6m + 8 –6m + 24 –18m + 8 Description
Answer:
-45m + 64
Step-by-step explanation:
To solve this, we are going to eliminate the parenthesis first:
(–9m + 12) –6m + 12 –6m + 8 –6m + 24 –18m + 8
= -9m + 12 - 6m + 12 –6m + 8 –6m + 24 –18m + 8
Now we're going to sum up all the terms that have an "m" and all the independent terms
=(-9m -6m - 6m - 6m - 18 m) + (12+12+8+24+8)
= - 45m + 64.
Thus, the expression is -45m + 64.

A cubic foot of water weighs about 62.5 pounds. if an aquarium is 18 feet long, 10 feet deep, and 12 feet wide, what's the approximate pounds-per-square-inch pressure (psi) on the bottom of the tank?
To find the psi on the bottom of an 18x10x12 feet aquarium, calculate the total weight of water, 135,000 pounds, and divide it by the bottom area in square inches, resulting in approximately 4.34 psi.
Explanation:To calculate the pounds-per-square-inch pressure (psi) on the bottom of the aquarium, we need to determine the weight of the water above a single square inch of the aquarium's bottom.
Given that the aquarium dimensions are 18 feet long, 10 feet deep, and 12 feet wide, we first calculate the volume of water in the aquarium by multiplying these dimensions together, which gives us 2160 cubic feet.
Next, since we know that each cubic foot of water weighs about 62.5 pounds, the total weight of the water in the tank can be found by multiplying the volume by this weight, resulting in 135,000 pounds (2160 cubic feet * 62.5 pounds/cubic foot).
To find the pressure in psi, we divide this total weight by the area of the bottom of the tank in square inches.
The tank bottom is 18 feet by 12 feet, which is 216 square feet or 31,104 square inches (216 square feet * 144 square inches/square foot).
Dividing 135,000 pounds by 31,104 square inches, we get approximately 4.34 psi pressure exerted on the bottom of the tank.
The high school dance team is learning a new routine to a song that lasts 3 minutes and 41 seconds, or 221 seconds total. Yesterday, they covered the first 45 seconds of the song at practice. They learn an average of 22 seconds of the dance in an hour. Let h represent the time, in hours, it will take the team to learn the entire dance. Which equation represents this situation, and how long will it take?
A. 221 = 22h; 11 hours
B.221 = 22h - 45;12 hours
C.221 = 22h + 45; 8 hours
D. 221 = 45h + 22; 5 hours
Answer:
Option C.
Step-by-step explanation:
High school dance team is learning a new routine to a song that lasts 221 seconds.
Yesterday they covered the first 45 seconds for the song at practice.
They learn an average of 22 seconds of dance per hour.
If they learned the dance for h hours then total time taken for routine will be = (22h + 45)
Therefore, equation that represents the this situation will be
22h + 45 = 221
22h = 221 - 45
22h = 176
h = [tex]\frac{176}{22}=8[/tex]
Total hours taken will be 8 hours.
Therefore, option C will be the answer.
