A dirt bike has been marked down 12% and now costs $4286.70. What was the original cost?

Answers

Answer:

$4871.25

Step-by-step explanation:

You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:

0.88x = 4286.70

You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:

x = 4871.25

QUESTION:
What is mBDG?

Answers

Answer:

242

Step-by-step explanation:

Circles have a total of 360°

mDBG does not include mBA or mGA

This means that mDBG = 360 - ( mBA + mGA )

mBA = 28° ( this is given )

mGA = 90° ( this is also given; it's indicated by the right angle )

Thus, mDBG = 360 - ( 28 + 90 )

28 + 90 = 118

mDBG = 360 - 118

360 - 118 = 242

Hence, mDBG = 242

please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!

Answers

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that  [tex]cos(x)=\frac{28}{39}[/tex]

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side

[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

total surface area of cylinder=?

we have

total surface area of cylinder=2πr²+2πrh

2πr(r+h)2π*2(2+8)40π or 125.66cm²

total surface area of cylinder40π or 125.66cm².

Question :-

Find the surface area of the cylinder.

___________________

Solution :-

Given Information :-

Radius of the Cylinder ➢ 2 cmHeight of the Cylinder ➢ 8 cm Value of π (pi) (not given) ➢ 3.14

To Find :-

Surface Area of the Cylinder

Formula Used :-

Area of cylinder = 2πr( r + h )

Calculation :-

Substituting the values given in the formula, We get,

⇒ Area of Cylinder = 2 × 3.14 × 2 ( 2 + 8 )

⇒ Area of cylinder = 2 × 3.14 × 2 ( 10 )

⇒ Area of cylinder = 2 × 3.14 × 20

Calculating further, We get,

Area of cylinder = 125.66 cm²

___________________

Final Answer :-

Area of cylinder = 125.66 cm²

Name the conic section formed when a plane cuts a right circular cone parallel to its base.

1) circle
2)parabola
3)ellipse
4) hyperbola

Will mark it the brainliest plsss fast!

Answers

Answer:

option 1.

circle

Step-by-step explanation:

A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.

What determines the shape of the section now, is the angle at which the cone was sliced.

Normally, the base of a cone is a circle.  If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.

If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.

On a ship the ratio of crew members to passengers is 1:15. There are 540 passengers. How many crew members are there?​

Answers

Answer: 36

Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540

Answer:

36 Crew members

Step-by-step explanation:

Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.

Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.

Double checking your answer:

1/15=0.06666666667...

36/540=0.06666666667...
