Alcia received a $75 gift certificate for her birthday. She went to a boutique to buy some T- shirts at $7 each and some socks for $2.50 a pair. If T represents the number of T-Shirts, and S represents the number of pairs of socks she bought, write an inequality that would determine the number of T-shirts and pairs of socks she could buy. HURRY PLEASE
T represents the number of T-Shirts
S represents the number of pairs of socks she bought
Each T-shirt cost $7, so 'T' T-Shirts will cost 7T
Each Pairs of socks cost $2.5, so 'S' pair of socks cost 2.5S
[tex] Total \; cost\; =\; T-shirts \; cost \; +\; Pair \; of \; socks\; cost \\ \\ Total \; Cost \; =\; 7T+2.5S\\ \\ [/tex]
Total cost should be less than or equal to 75 dollars.

Match the pre-image, and its clockwise rotation, with the coordinates of its image. 1. (5, 2); 90° (-2, -5) 2. (5, 2); 180° (2, -5) 3. (5, 2); 270° (-2, 5) 4. (-5, 2); 90° (5, 2) 5. (-5, 2); 180° (-5, -2) 6. (-5, 2); 270° (2, 5) 7. (-2, 5); 90° (-5, 2) 8. (5, -2); 180° (5, -2)
Answer:
(2,5) = (-5,2); 90°
(2,-5) = (5,2); 90°
(-2,-5) = (-5,2); 270°
(5,-2) = (-5,2); 180°
(-2,5) = (5,2); 270°
(5,2) = (-2,5); 90°
(-5,2) = (5,-2); 180°
(-5,-2) = (5,2); 180°
Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.
Hope this helps!

LM=7, LN=10, MN=5, What can you conclude about the angle measures
Given the lengths stated, we conclude that triangle LNM is a right triangle. Angle LNM would be the right angle, and angles NML and NLM can be calculated with trigonometry if necessary.
Explanation:Given the lengths of triangle LNM with LM = 7, LN = 10, and MN = 5, we can infer that this triangle is a right triangle. This is concluded through the use of the Pythagorean theorem, which defines that in any right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. Specifically, in this case, we can observe that 10² (LN) equals to 7² (LM) + 5² (MN), because 100 equals 49 + 25. Consequently, since LN is the hypotenuse, angle LNM is the right angle, and angles NML and NLM can be found using trigonometric functions if needed.

how do you solve twelve less than the quotient of a number and 7 is -2
Remark
One of the things you need to do is learn to read phrase by phrase.
What is the quotient of a number and 7? That meas you have a number, x, and it is divided by 7. What you do that the answer you get is the quotient.
x/7 is what you know so for. Now the first part says you take 12 away from that.
x/7 - 12 is what you have after doing that.
The result you get is - 2
x/7 - 12 = - 2 Add 12 to both sides
x/7 - 12 + 12 = - 2 + 12
x/7 = 10 Now multiply by 7
x = 10 *7
x = 70 <<< Answer the number is 70

Gloria Trench checked her gas mileage and found that she had used 16.6 gal of gas to travel 372 mi. At this rate, how many gallons will she use to travel from San Francisco to Washington, D.C., a distance of 2,850?
Using the rate of miles per gallon for Gloria's car, we calculated that she will need approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C.
Explanation:To solve this problem, we'll use the principle of ratios.
First, we find the rate of miles per gallon for Gloria's car by dividing the distance travelled by the gallons used:
372 miles ÷ 16.6 gallons = 22.4 miles per gallon
With this information, we can calculate how many gallons Gloria will need to travel from San Francisco to Washington D.C., which is a distance of 2850 miles:
2850 miles ÷ 22.4 miles per gallon = 127.2 gallons
So, Gloria will use approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C., at her current rate.

Laura’s cell phone service costs $65 per month, plus an additional $0.10 per text message sent. The table below shows the cost for Zach’s cell phone service based on the number of texts messages he sends. How much cheaper is Zach’s cell phone service than Laura’s when no text messages are sent?
When no text messages are sent, Zach's cell phone service is $55 cheaper than Laura's each month.
Explanation:Laura's cell phone service costs $65 per month regardless of how many text messages she sends. On the other hand, Zach's cell phone service cost is represented by the variable equation $10 = $2× QRT + $.05 × QPC. However, since no text messages are sent in this scenario, the number of text messages (QPC) is 0. Therefore, all the terms in the equation that involve QPC becomes zero. Hence, Zach's cell phone service costs $10 per month when no text messages are sent. So if we compare Laura's cell phone costs to Zach's without sending any text messages, Zach is paying $65 - $10 = $55 less than Laura each month.

What is the 32nd term of the arithmetic sequence where a1 = −33 and a9 = −121? −396 −385 −374 −363
The formula to find the general term of an arithmetic sequence is,
[tex] a_{n} =a_{1} +(n-1)d [/tex]
Where [tex] a_{n} [/tex]= nth term and
[tex] a_{1} [/tex] = First term.
Given, a9 = −121. Therefore, we can set up an equation as following:
[tex] -33+(9-1)d = -121 [/tex] Since, a1 = -33
- 33 + 8d = -121
-33 + 8d + 33 = -121 + 33 Add 33 to each sides of the equation.
8d = -88.
[tex] \frac{8d}{8} =\frac{-88}{8} [/tex] Divide each sides by 8.
So, d = - 11.
Now to find the 32nd terms, plug in n = 32, a1 = -33 and d = -11 in the above formula. So,
[tex] a_{32} = -33 +(32 -1) (-11) [/tex]
= -33 + 31 ( -11)
= - 33 - 341
= -374
So, 32nd term = - 374.

Samantha works at a nursery where she pots plants. It takes her 1 1/2 hours to pot 12 plants. How many plants can Samantha pot in hour?
Samantha can pot 8 plants in one hour.
To calculate how many plants Samantha can pot in one hour, we need to determine the rate at which she pots plants. She currently pots 12 plants in 1 1/2 hours, which is equal to 1.5 hours.
To find the rate, we divide the number of plants by the number of hours:
12 plants /1.5 hours=8 plants per hour
Therefore, Samantha can pot 8 plants in one hour.

Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Each box has six sides, and the dimensions of each side are:
12 x 10, 12 x 10, 12 x 3, 12 x 3, 10 x 3, and 10 x 3 inches.
The total surface area of each box is:
2(12 x 10) + 2(12 x 3) + 2(10 x 3) = 240 + 72 + 60
= 372 square inches.
Since there are 12 boxes, the total surface area of all the boxes is:
= 12 x 372
= 4,464 square inches.
Therefore,
Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes.
