BRAINLIEST INCLUDED! The cost of a pair of boots was $40. They now cost $25. Determine the percent of decrease. Enter your response with an explanation of your process.

Answers

Answer:

37.5 percent

Step-by-step explanation:

First, work out the difference (decrease) between the two numbers you are comparing(which is 15 in this case) . Next, divide the decrease by the original number and multiply the answer by 100.(15/40=0.375 times 100=37.5) If the answer is a negative number, this is a percentage increase

I think the answer would be 37.5% decrease. The boots are $15 less than before so you set 15 over 40 equals x over 100. Cross multiply 40 by x and 15 by 100 to get 40x=1,500. You then divide 1,500 by 40 to get x=37.5 which is your percent decrease. I hope this helped :)

2. What is the sales price for an Xbox 360 that originally sells $230 if it is on sale for 28% off the original price?

3. What is the difference between discounting a $45,000 car by 25% versus marking up the price of the car by 25%?

4. How much would you pay for the discounted price of the car including 8.875% sales tax?

5. How much would you pay for the marked up price of the car including 8.875% sales tax?

6. If Thomas helped you buy the car that was on sale in question #3, he is entitled to a 6% commission at Sherman Auto Mall. How much commission will he earn for the car that was "on-sale" in #3?

Answers

see below

Step-by-step explanation:

2.) $230 x 28% = $64.40

$230 - $64.40 = $165.60 sales price

3.) $45,000 × 25% = $11,250

$45,000 - $11,250 = $33, 750 discount price

$45,000 + $11,250 = $56,250 mark up price

$56,250 - $33,750 = $22,500 answer

4.) $33,750 x 8.875% = $2995.31

$33,750 + $2995.31 = $36,745.31 with tax

5.) $56,250 x 8.875% = $4,992.19

$56,250 + $4,992.19 = $61,242.19 with tax

6.) $33,750 x 6% = $2,025.00 Tom's commision

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?

Answers

Answer:

36 minutes

Step-by-step explanation:

If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:

30 / 5 = 6

So, if he were to jump a sixth time:

30 + 6 = 36

Therefore, Dracula jumps 1 time per 6 minutes.

diffrent angles kind of like an editing grid to move stuff

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180

Answers

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.

Claire thinks that if she draws a parallelogram with 2 congruent sides, it must be a rhombus. Jacob thinks that she would need to draw a parallelogram with at least 3 congruent sides before she could be sure it was a rhombus. Who is correct, if anyone, and why?
Only Claire is correct, because if the figure is a parallelogram and 2 sides are congruent, it must have all 4 sides congruent.
Only Jacob is correct, because a parallelogram with 4 congruent sides must have 2 pairs of opposite sides that are congruent.
Both are correct because if a figure has at least 2 congruent sides, it must have 4 congruent sides.
Neither is correct because one would need to draw 4 congruent sides in order to be sure the figure was a rhombus.

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1

Answers

Answer:

5/8 divided by 5/8 = 1

Step-by-step explanation:

First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.

[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]

Now, multiply both sides by 5 to get rid of the fraction.

[tex]8g = 5[/tex]

divide both sides by 8

[tex]g = 5/8[/tex]

It’s asking you to what 5/8= 1 to do basically you have to multiply the 8 to both sides and then you probably will get your answer but I’m not to sure

Drew wants to wallpaper his bedroom. The room is 10 ft long, 12 ft wide, and 8 ft tall. How many square feet of wallpaper does he need? So I got this question wrong and is wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain.

Answers

Answer:

you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S

Step-by-step explanation:

let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total, you need 160+192= 352 square feet of wallpaper

A business named Beyond Boxes is considering adding a box in the shape of a triangular prism as shown. How much cardboard will be needed to make this design?
A.96 cm2

B.102 cm2

C.108 cm2

D.76 cm2

Answers

Answer:

120

Step-by-step explanation:

108 cm² cardboard will be needed to make this design.

As per the given data:

The shape of the box is a triangular prism, and all the dimensions are given in the diagram.

A polyhedron with two triangular bases and three rectangular sides is referred to as a triangular prism. It is a three-dimensional form with two base faces, three side faces, and connections between them at the edges.

To find the cardboard that will be needed to make this design:

= Total surface area of the triangular prism.

= Area of 2 triangles + area of 3 rectangles

= 2 × ½ × 3 × 4 + 4 × 8 + 5 × 8 + 8 × 3

= 12 + 32 + 40 + 24

= 108 cm²

Hence, 108 cm² cardboard will be needed to make this design.

Tropical masses of air form near the equator or near a low pressure area true or false In 1202, a man named Leonardo of Pisa, otherwise known as Fibonacci, wrote a book entitled Liber Abaci. Fibonacci was the first Western European mathematician to introduce the sequence named for him, though it had been identified by earlier mathematicians and grammarians from India. Fibonaccis sequence is a series of numbers in which each number is the sum of the two preceding numbers, thus: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, and so on. Fibonaccis work in mathematics is complex; nevertheless, the series has captured the imagination of popular culture. Because his sequence appears in naturefor example, the branching of trees, the scales of pinecones, the spirals of seashells, and the curves of wavesartists and writers have given it almost mystical significance. Its featured in The Da Vinci Code, for example, as having a role in the supposedly secret messages found in Leonardo da Vincis art. Although the mystical interpretations are based on fiction, Fibonaccis remarkable accomplishment actually happened in the early 1200s.Which option below would be an acceptable revision of the underlined selection?a. artist'sb. artistsc. artists's -9(8x 8) = 8(-7 - 10x) How do the flaws and immorality of the Greek gods compare to your personal stance/belief/unbelief of god?
