skateboarding ramp is 12in. high and rises at an angle of 23 degrees. How long is the base of the​ ramp? Round to the nearest inch.

Answers

Answer 1

Answer:

the length of the base of the ramp is 28.27 inches

Step-by-step explanation:

The computation of the length of the base of the ramp is shown below:

Let us assume x be the length of the base of  the ramp

Now the following formula should be used

tan = opposite ÷ adjacent

tan 23 degrees = 12 ÷ x

x = 12 ÷ tan 23 degrees

= 12 ÷ 0.42447482

=28.27 inches long

Hence, the length of the base of the ramp is 28.27 inches

-1/3x

What term can you add to 5/6x -4 to make it equivalent to 1/2x - 4?

First I see the constants (-4) are equal to each other, so I don’t need to add anything to them.

5/6x and 1/2x are different though, so I know I need to add something, let’s call it y, to 5/6x to make it equal 1/2x

To add fractions, they have to have the same denominator. 1/2x becomes 3/6x.

5/6x + y = 3/6x
Subtract 5/6x from both sides
y = -2/6x

-2/6x can be simplified to -1/3x, so -1/3x is the answer.

So far, Keith has burned 604.3 calories. He wants to burn a total of 700 calories. How many more calories must Keith burn?

Answers

so to do this you need to use subtraction to find it how many more calories he needs to burn 700. so you would do 700 - 604.3 to get an answer of 95.7! :)

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?

Answers

Answer:

189

Step-by-step explanation:

Given data

Initial population=350

Rate = 6%

TIme= 10 years

Let us apply the compounding expression

A=P(1-r)^t----------The negative sign is due to decreasing value

substitute

A= 350(1-0.06)^10

A=350(0.94)^10

A=350*0.5386

A=188.51

Hence the approximate population will be 189

Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The ratio of distances is ...

  Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)

  = 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7

Neptune is about 77.76 times as far from the Sun as Mercury is.

What is the solution or solutions to the equation x + 5 = 5x ?

Answers

Answer:

x = 5/4

Step-by-step explanation:

The solution or solutions to the equation x+5=5x is 5/4. It can also be written as 1.25. This is because you move the constant to the right-hand side and change its sign, then you collect like terms, divide both sides of the equation by -4.

In the given diagram , TY is a tangent to the circle TVS . If <SVT = 48° and |VS| = |ST| . What is < VTY.​

Answers

Answer:

84°

Step-by-step explanation:

∠VTY is the tangent chord angle

Tangent chord angle is the half of the intercepted arc

∠TSV is the inscribed angle.

Inscribed angle is the half of the intercepted arc

Since both of the mentioned angles refer to same arc, they are of same value.

∠VTY = ∠TSV

ΔTVS is isosceles as VS = ST, therefore the opposite angles are same.

m∠T = m∠V = 48°

The measure of angle S

m∠S = 180° - 2*48° = 84°

The required angle

m∠VTY = 84°

Answer:

∠VTY = 84°

Step-by-step explanation:

because ΔTSV is isosceles (ST = SV) then ∠VTS = ∠SVT = 48°

Then ∠VST = 84°   (180 - 48 - 48 = 84)

Well, I'm going back to the picture is worth a thousand words again.

Sketch attached:

A line from S to the center bisects ∠VST into two 42° angles.

A line from T to the center forms a 42° angle with line ST.

48°-42° = 6° = angle from perpendicular line CTR to line VT.

90° - 6° = 84° for ∠VTY

Brenda likes to swim when she is at her cottage. She swam 12 m north from her dock, and then 60 m east. How far will she have to swim if she wants to go directly back to the dock?

Answers

Answer:

72 m

Step-by-step explanation:

If Brenda is going 12m north and 60m east, that's a total of 72m because 12+60 = 72, so if Brenda wants to come directly back to the dock she will just have to follow her footsteps back 72m.

decreased by 2 cm, the area would decrease by 21 cm² Find the dimensions of the original
rectangle (Round your answer to 3 significant figures where necessary.)​

Answers

Answer:

Let the breadth be x and the length be y .

Original area =x.y

Now

length=y+2

breadth=x-2

Area=x.y-28 or x-2 × y+2

xy-28=(x-2)(y+2)

xy-28=xy+2x-2y-4

2y-2x=24

y-x=12

y=12+x

length=y-1

breadth=x+2

Area=xy+33 or (x+2)(y-1)

xy+33=(x+2)(y-1)

xy+33=xy-x+2y-2

35=2y-x

2y=35+x

y=(35+x)÷2

12+x=(35+x)÷2

24+2x=35+x

x=35-24

x=11

y=23

Therefore length is 23cm and breadth is 11cm
