Year 1 number sold 725
Year 2 number sold 579
Year 3 number sold in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number of scooter sold in year 4

Answers

Answer 1

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1   725  

Year 2   579

Year 3   696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

[tex]\frac{112}{100} =\frac{x}{2000}[/tex]

We solve through cross multiplication of numerator and denominator of the opposite fraction.

[tex]112(2000)=100(x)\\224000=100x\\2,240=x[/tex]

What is Y=6x-6 and -3x-3y=-24
System of substitution

Answers

Answer:

x = 2

y = 6

Step-by-step explanation:

y= 6x - 6

-3x- 3y= -24

to find the value of x:

- 3x - 3 (6x - 6)= -24

- 3x - 18x + 18= -24

-21x + 18 = -24

-21x= -42

x = 2

Now, to find the value of y:

(substitute x into the equation)

y = 6 x - 6

y = 6 (2) - 6

y = 12 - 6

y = 6


Harper knows he is 50 yards from the school. The map on his phone show that the school is 3/4 inches from current location. How far is Harper from home if map shows the distance as 3 inches

Answers

Answer: 200 yards


Step-by-step explanation:

So if 3/4 inches on the map is equal to 50 yards then you could divide the 3 inch distance from him to his home by 3/4 and then multiply that answer by 50. So 3 ÷ 3/4 = 4. 4 * 50 = 200. He is 200 yards from his home.

Answer:

Harper is 200 yards away home.

Step-by-step explanation:

To solve this problem, we use the rule of three, if 50 yards represents 3/4 inches, how many yards would represent 3 inches?

[tex]x=3in\frac{50yd}{\frac{3}{4}in } =3\frac{200}{3}yd=200yd[/tex]

So, 3 inches represents 200 yards, that means Harper is 200 yards away home.

Remember that the rule of three is just about using the ratio that the problem already gave.

Therefore, the answer is 200 yards.

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inches tall. Now they are 72 inches tall. What is the percent of increase in the height of the stalks?

Answers

Final answer:

The percentage increase in the height of the corn stalks is 20%. This was calculated by subtracting the old height from the new height, dividing by the old height, and then multiplying by 100.

Explanation:

The question is asking about the percentage increase in the height of the corn stalks that Alice planted. The stalks were previously 60 inches tall and now, they are 72 inches tall.

The formula to calculate the percentage increase is:

[(New Value - Old Value) / Old Value] x 100%

Substituting the given values into the formula, we get

[ (72 - 60) / 60 ] x 100%

This simplifies to [12/60] x 100%, which equals to 20%.

Therefore, there has been a 20% increase in the height of the corn stalks.

6691 ÷28. solved by long divison

Answers

When you dived them in the normal way you'll get a decimal so you'll round and get 238.96

To calculate 6691 divided by 28 using long division, divide each set of numbers step by step to arrive at a quotient of 238 with a remainder of 27, resulting in a decimal of approximately 238.96 when rounded.

The question involves the process of long division which is a method used in arithmetic. The student is trying to divide 6691 by 28:

Divide 66 by 28, which goes 2 times. Write 2 above the division bar, to the right of the first quotient place.

Multiply 2 by 28, which is 56, and subtract that from 66 to get a remainder of 10. Bring down the next digit, 9, to make 109.

Divide 109 by 28, which goes 3 times. Write 3 on the division bar. Multiply 3 by 28 (equals 84) and subtract from 109 to get 25.

Bring down the next digit, 1, to make 251. Divide this by 28, which goes 8 times. Eight times 28 is 224. Subtract this from 251 to get 27.

27 is less than 28, so the division process stops here. The answer up to this point is 238, with a remainder of 27.

The long division calculation of 6691 divided by 28 is 238 with a remainder of 27 or as a decimal, 238.96.

What is the simplified form of the rational expression below? 6x^2-54/5x^2+15x

Answers

Final answer:

The simplified form of the rational expression 6x^2-54/5x^2+15x is 6(x - 3)/5x. This was achieved by factoring the original expressions, cancelling out common terms, and applying the difference of squares formula.

Explanation:

The subject here is the simplification of a rational expression. First, let's factor the numerator (6x^2 - 54) and the denominator (5x^2 + 15x). The common factor in the numerator is 6 and in the denominator is 5x. After factoring we get:

6x^2 - 54 = 6(x^2 - 9)

5x^2 + 15x = 5x(x + 3)

Now, we can use the property a^2 - b^2 = (a + b)(a - b) to further simplify x^2 - 9 to (x - 3)(x + 3). This gives our new numerator as 6(x - 3)(x + 3).

The denominator 5x(x + 3) remains the same. Therefore, the simplified form of the rational expression is 6(x - 3)(x + 3)/5x(x + 3). The (x + 3) terms can be cancelled out leaving us with the final simplified rational expression of:

6(x - 3)/5x

Miss Johnson drives to work everyday when she left for work one day the automator mileage gauge on her car read 38643.8 when she returned to her house at the end of the day the automator red 38 points 668.6 if she didn't drive anywhere else during the day but to work and back how many miles is it from her house to her work explain how you got your answer

Answers

Answer:

Distance from her house to her work = 12.4 Miles

Step-by-step explanation:

Given :-

==> Automator mileage gauge read 38643.8 Miles before she left to work.

==> Automator mileage gauge read 38668.6 Miles after she came home from work.

==> She didn't drive anywhere else during the day. home to work & work to      home.

Car driven during the day = 38668.6 - 38643.8

                                           = 24.8 Miles

Let the distance from home to work be X

*It is assumed that Distance from home to work = Distance from work to home

So, Distance from work to home = X

Total distance driven during the day = Distance from home to work + Distance from work to home

Total distance driven during the day = X + X

                                                    24.8 = 2X

                                                    24.8 ÷ 2 = X

                                                    12.4 = X

A 30m tall building casts a shadow. the distance from top of the building to the top of the shadow is 36m. Find the lengths of the shadow

Answers

Final answer:

Using the Pythagorean theorem, the length of the shadow cast by a 30m tall building, with a diagonal distance of 36m from the top of the building to the top of the shadow, is calculated to be approximately 19.9 meters.

Explanation:

To find the length of the shadow cast by a 30m tall building, we can use the Pythagorean theorem. This theorem relates the lengths of the sides of a right triangle. Here, the building and its shadow form the two legs of a right triangle, and the line from the top of the building to the top of the shadow is the hypotenuse.

Let's denote:

The height of the building (opposite side) as O = 30m

The length of the shadow (adjacent side) as A

The distance from the top of the building to the top of the shadow (hypotenuse) as H = 36m

According to the Pythagorean theorem, we have:

O2 + A2 = H2

Plugging in the known values, we get:

302 + A2 = 362

900 + A2 = 1296

A2 = 1296 - 900

A2 = 396

A = √396

A ≈ 19.9m (rounded to one decimal place)

Therefore, the length of the shadow is approximately 19.9 meters.

Which of the following is the equation of a circle whose center is at the origin and whose diameter has end (-1,2) and (1,-2)

Answers

Answer:

x² + y² = 5

Step-by-step explanation:

The circle with center (h, k) and radius r has equation ...

... (x -h)² + (y -k)² = r²

You can find r² using the Pythagorean theorem or the distance formula, or you can simply calculate what it needs to be to make one or the other of the points lie on the circle.

For (h, k) = (0, 0), the equation is ...

... (x -0)² + (y -0)² = r²

Using (-1, 2) for (x, y), we can find r² as ...

... (-1 -0)² + (2 -0)² = r² = 1 + 4 = 5

Then the circle equation is ...

... x² + y² = 5

Given: △AKL, AK=9 m∠K=90°, m∠A=60° Find: The perimeter of △AKL The area of △ AKL

Answers

Answer:

Perimeter of ΔAKL is, [tex]27 +9 \sqrt{3}[/tex] units.

Area of  ΔAKL is, [tex]\frac{81\sqrt{3} }{2}[/tex] square units

Step-by-step explanation:

Given: In ΔAKL , AK = 9 units , [tex]m\angle K = 90^{\circ}[/tex] and [tex]m\angle A= 60^{\circ}[/tex].

In ΔAKL

[tex]\tan (A) = \frac{KL}{AK}[/tex]

Substitute the value AK = 9 units and [tex]m\angle A =60^{\circ}[/tex] to solve for KL ;

[tex]\tan(60^{\circ}) = \frac{KL}{9}[/tex]

[tex]\sqrt{3} = \frac{KL}{9}[/tex]

⇒[tex]KL = 9\sqrt{3} units[/tex]

In right angle ΔAKL,

Using Pythagoras theorem;

[tex]AL^2 = AK^2+KL^2[/tex]                     ......[1]

Substitute AK = 9 units and [tex]KL =9\sqrt{3} units[/tex] in [1] to solve for AL;

[tex]AL^2 = 9^2+(9\sqrt{3})^2[/tex]

[tex]AL^2 = 81+(81 \cdot 3)[/tex]

[tex]AL^2 = 81+243 = 324[/tex]

[tex]AL = \sqrt{324} = 18 units[/tex]

Perimeter of triangle is the sum of all the sides.

Perimeter of triangle AKL = AK +KL +AL = [tex]9 + 9\sqrt{3} + 18 = 27 +9 \sqrt{3}[/tex] units.

Formula for Area of right angle triangle is given by:

[tex]A = \frac{1}{2} Base \times Height[/tex]

Area of triangle AKL=  [tex]\frac{1}{2} (9\sqrt{3}) \times (9)[/tex]

                                  = [tex]\frac{81\sqrt{3} }{2}[/tex] square units




Final answer:

The perimeter of triangle AKL is approximately 29.09 m, and the area is 20.25 m², calculated using the properties of a 30°-60°-90° right triangle.

Explanation:

To find the perimeter of △AKL, we need to determine the lengths of all three sides. We know that AK = 9 m, ∠K = 90° (which makes △AKL a right triangle), and ∠A = 60°. Because the angles in a triangle add up to 180°, ∠L must be 30° (180° - 90° - 60°). In a 30°-60°-90° right triangle, the lengths of the sides are in the ratio 1:√3:2. Thus, if AK is the side opposite the 60° angle, AL must be half of AK, and KL must be AK times √3.
Therefore, AL = ½ × 9 m = 4.5 m, and KL = √3 × 9 m ≈ 15.59 m. The perimeter is the sum of AK, AL, and KL: 9 m + 4.5 m + 15.59 m ≈ 29.09 m.

The area of △AKL can be found using the formula for the area of a right triangle, which is ½ × base × height. AK and AL can serve as the base and height, respectively, so the area A is ½ × 9 m × 4.5 m = 20.25 m².
