The side on a clip board appears to be a right triangle. The leg lengths are 2 millimeters and 2.1 millimeters and the hypotenuse is 2.9 millimeters. Is the side of the clip a right triangle?

Answers

Answer 1

Answer:

Yes, it is a right angle triangle

Step-by-step explanation:

Let leg lengths be y and z

Y = 2mm

Z = 2.1mm

Let x represent hypothenus

X = 2.9mm

To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)

x² = y² + z²

x² = 2² + 2.1²

x² = 4 + 4.41

x² = 8.41

Take the square root of both sides

x = √(8.41)

x = 2.9mm

Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?

Answers

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y = $551.97 (a)

=================== -

33x = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Ribeye is 18.54 and salmon is 9.78

A rectangular prism is 2 inches by 4 inches by 6 inches.

Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”

Do you agree with Kimaya? Explain or show your reasoning.

Answers

No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.

So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.

Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.

No, I do not agree with Kimaya, and heres why.

Simple Explanation: 2/5 in. cubes are more than 1/5 in. cubes, so 1/5 in. cubes would take 2x more to fill than 2/5 in.

Complex Explanation: 2 in. x 4 in. x 6 in. is 48 cubic in. and to fill 48 cubic in. using 2/5 in. per cube, it would be 120. as for 1/5 in., to fill 48 cubic in. with that would be 240. Easier way to think of it is that 2/5 in. cubes are already 120 and 1/5 would be doubling that so all you gotta do is multipy 120 x 2 since filling it with 1/5 would be 2x the amount than 2/5.

A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?

Answers

Answer:

$151.20

Step-by-step explanation:

The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:

Discount = 30% x $200 = $60

The sale price of the Nintendo Switch Lite after the discount is:

Sale price = $200 - $60 = $140

The sales tax in the state is 8%, so the tax amount on the sale price is:

Tax amount = 8% x $140 = $11.20

Therefore, the final cost for the consumer, including tax, would be:

Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20

Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.

not really a math wizard but i learnt this a month ago

200 x 30% is 60 then i guess you subtract 60 from 200 which is 140 then im pretty sure you multiply the sales tax aka 8% to 140 which would be 8% x 140 = 11.2 then you add 11.2 to 140 and i think that gives you 151.2

Do 572 x 100 first to get 57,200.

Then divide 57,200 by 85 to get around 672 students.

However, I haven't done these kinds of questions in a long time, therefore I could be wrong.

On a snowy day 85% of the students of Wilson high school were present., There were 672 students enrolled at Wilson high school.

To find out how many students were enrolled at Wilson high school, we can use the information given in the question. We are told that 85% of the students were present on a snowy day, and that 572 students were present. To find the total number of students enrolled, we can set up a proportion: Present students / Total students = Percentage present / 100 Let's plug in the values we know: 572 / Total students = 85 / 100 To solve for the total number of students, we can cross-multiply and solve for Total students: 572 * 100 = Total students * 85 57200 = Total students * 85 Dividing both sides by 85: 57200 / 85 = Total students Total students = 672 Therefore, there were 672 students enrolled at Wilson high school.

Ruth's dining room is 6 yards wide and 9 yards long. Ruth wants to install a new wood floor. It will cost $8.00 per square yard. How much will Ruth's new floor cost?

Answers

Ruth’s new floor cost $432.

The cost can be calculated as follows.

First, calculate the area of dining room. Use the formula of rectangle area (width x length)

Area = width x length

= 6 yd x 9 yd

= 54 sq yd

Second, calculate the total cost.

Cost = 54 sq yd x $ 8 per sq yd

= $ 432

Hence it cost $ 432 to install the new wood floor.

The rent is $2,000 per month and includes all utilities. The owner, JJ, started the business with $25,000 she received on her 30th birthday from her great aunt. She is very excited about starting her business and has lined up her first client who wants a wedding cake for a March 1st wedding. The client has paid a $400 deposit for this custom $1,200 three tier cake. Before the business opened, JJ spent $5,000 cash on a new oven ($2,500), a display case ($600), furniture for the store front ($1,100) and a backlit sign for the front of the store ($800).
