How far from the door must a ramp begin in order to rise 3 feet with an 8 degree angle of elevation

Answers

Answer 1

Answer:

Step-by-step explanation:

We know that the angle of elevation is 8 degrees.

We know that the height of the opposite side of the angle is 3 feet.

We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)

We can do this with tangent

[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]

Answer 2

The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets

Angle of elevation = 8°Rise = opposite = 3 feets Distance, d = adjacent

Using SOHCAHTOA :

Tanθ = Opposite / Adjacent

Tan(8°) = 3 / d

0.1405408 = 3 / d

0.1405408d = 3

Divide both sides by 0.1405408 to isolate d

0.1405408d / 0.1405408 = 3 / 0.1405408

d = 21.34 feets

Therefore, the distance of the ramp from the door should be 21.34 feets

I need help

Answers

wouldn’t it be y=-4x+1
Answer:  y = -4x+1

========================================================

Explanation:

The two points on this line are (-1,5) and (0,1)

Let's use the slope formula

m = (y2-y1)/(x2-x1)

m = (1-5)/(0-(-1))

m = (1-5)/(0+1)

m = -4/1

m = -4

The slope is m = -4

If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

With m = -4 and b = 1, we go from y = mx+b to y = -4x+1

The driver of a car traveling at 60 ft/sec suddenly applies the brakes. The position of the car is s(t) = 50t - 2t2, t seconds after the driver applies the brakes. How many seconds after the driver applies the brakes does the car come to a stop? (4 points)

Answers

Answer:

t=12.5s

Step-by-step explanation:

s(t) = 50t - 2t^2

v(t) = 50 - 4t

a(t) = -4

When v(t) = 0, the car stops.

v = u +at

0 = 50 + (-4)t

t = 12.5

Misha found that the equation –|2x – 10| – 1 = 2 had two possible solutions: x = 3.5 and x = –6.5. Which explains whether or not her solutions are correct?

She is correct, because both solutions satisfy the equation.
She is not correct, because she made a sign error.
She is not correct, because there are no solutions.
She is not correct, because there is only one solution: x = 3.5.

Answers

She is not correct, because there are no solutions.

Explanation: If you isolate the absolute value by adding 1 both sides of the equation, you get -|2x-10|=3. There are no solutions, because the left side of the equation will always be negative and will never equal 3.

She is not correct, because there are no solutions. (Option C).

What is an equation?

An equation refers to any mathematical statement that contains the equality sign. Now we can see in the equation that there is a negative sign before the absolute value.

Now we have;

–|2x – 10| – 1 = 2

–|2x – 10| = 3

This is not possible because the absolute value does not return a negative value and the expression can never equal 3.

Thus, she is not correct, because there are no solutions.

1. Andrew went to FYE to buy music for the band. He spent a total of $112 on 14 music purchases. one Music CDs were on sale for $10 and cassettes were on sale for $3. How much did Andrew pay for each music CD and each cassette tape? Enter your one-sentence interpretation in the space below.​

Answers

Answer:

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

Step-by-step explanation:

Given that:

Total money spent = $112

Number of music purchases = 14

Cost of one Music CD = $10

Cost of one cassette = $3

To find:

How much money was paid for each music CD and each cassette.

Solution:

Let the number of Music CDs purchased = [tex]x[/tex]

Money spent on Music CDs = [tex]\$10\times x[/tex]

Then the number of cassette tapes purchased = [tex]14-x[/tex]

Money spent on cassette tapes = [tex]\$3\times (14-x)[/tex]

As per the question statement:

[tex]10x+3(14-x)=112\\\Rightarrow 10x+42-3x=112\\\Rightarrow 7x=112-42\\\Rightarrow 7x=70\\\Rightarrow x =10[/tex]

Therefore, number of Music CDs purchased = 10

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

And number of cassette tapes purchased = 14 - 10 = 4

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

There are 6 people in George's family. How much did George's mom pay for tickets? Show how you found your solution.

Answers

Answer:

$75

Step-by-step explanation:

To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.

The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.

Using (4, 50), this means that 4 tickets cost $50.

Unit rate/constant of proportionality = y/x = 50/4 = 12.5

This means a ticket costs $12.5.

Therefore, 6 tickets would cost:

6 tickets × $12.5 = $75.

How many ways can six slices of pepperoni pizza and three slices of cheese pizza be divided among five students if one of the students is a vegetarian?

Answers

Answer: Vegan student gets 9/5 cheese slices

The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.

Step-by-step explanation:

6 slices of Pepperoni + 3 slices of cheese = 9 slices total.  We need to divide the slices among 5 students, 1 is vegan.

9 divided by 5 = 1 and 4/5 slices or  9/5 slices.

The 9 slices make 45/5 slices.

3 slices of cheese = 15/5 slices.

6 slices of pepperoni = 30/5 slices.

Vegan student gets 9/5 cheese slices. Leaving 6/5 slices or 12/10 slices of cheese, 12/10 divided by 4=3/10

The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.

5/5=10/10, 1/2=5/10, 3/10  

10/10 + 5/10 + 3/10 = 18/10=9/5 slices each person.

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

Given the translation maps the point J(1, 4) onto K(7, -3).

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.
