A ramp has a height of five feet and a horizontal distance of 200 ft. What is the angle of elevation?

A 16

(6) 5.5°

(C 25.1°

D

1.4°

€ 2.3°

Answers

Answer 1

Answer:

1.4°

Step-by-step explanation:

Given that :

Height of ramp, h = 5 feets

Horizontal distance = 200 feets

The angle of elevation :

Using trigonometry :

Tanθ = opposite / Adjacent

Tan θ = 5 / 200

Tan θ = 0.025

θ = tan^-1 (0.025) = 1.43

θ = 1.4°

Step-by-step explanation:

25 = 700

Y = 1260

Now you need to do cross multiplication .

25 X 1260=700Y

Since it's in a multiplying form you can simplify by dividing 700 by 25

1260=700Y/25

1260=28Y

Debbie is ordering a breakfast special at a diner that comes with eggs, bread, and a drink. The special offers the following options:
• The eggs can be scrambled or fried.
• The bread options are a biscuit, a slice of toast, or a bagel.
• The drinks options are orange juice, apple juice, coffee, or tea.
• Debbie will randomly choose each option in the breakfast special.
What is the probability Debbie
will choose fried eggs, toast,
and either coffee or tea?

A. 1/12
B. 4/9
C. 4/5
D. 1/24

Answers

Answer:

The probability Debbie will choose fried eggs, toast, and either coffee or tea is;

A. 1/12

Step-by-step explanation:

From the question, we have;

The number of options for preparing the eggs = 2 options

Therefore, the probability of either egg option chosen = 1/2

The number of options for the type of bread = 3

Therefore, the probability of either bread option chosen = 1/3

The number of options for the drink = 4

Therefore, the probability of either drink option chosen = 1/4

We add probabilities connected with an 'or' statement and multiply probabilities connected with an 'and' as follows;

The probability for Debbie to choose either coffee or tea = 1/4 + 1/4 = 1/2

Therefore, the probability Debbie will choose fried eggs, (and) toast, and either coffee (or) tea, P is given as follows;

P = 1/2 × 1/3 × 1/2 = 1/12

The probability Debbie will choose fried eggs, toast, and either coffee or tea = 1/12.

You are trying to heat up a cup of water with a butane lighter.

1) How much heat is transferred to the water if 200 g of water with a specific heat capacity of 4.184Jg°C changes from 22.3ºC to 35.7ºC? Answer in kJ.

2) If you burn 0.23 g of butane, what is the heat of combustion of butane in kJ/g?

Answers

Answer:

Step-by-step explanation:

Remark

The formula for this is

Heat = m * c * Δt

Givens

Heat = unknown

m = 200 grams

c = 4.184 Joules / grams oC

Δt = the change in temperature = 35.7 - 22.3 = 13.4

Solution

Heat = 200 * 4.184 * 13.4

Heat = 11213 Joules

Heat = 11.2 Kj

It's hard to get the correct number of sig digs because the 200 is not qualified in any way.

Part 2.

This can really puzzle you until you know that heat given up = the heat taken on. The heat taken on was 11.2 Kj. The Butane lighter must have given that heat on.

Heat of Combustion = Heat Given Up / Number grams burned.

Heat of Combustion = 11.2 Kj / 0.23 grams

Heat of Combustion = 48.8 Kj / gram

[tex]\boxed{\boxed{\sf x=\frac{\sqrt{217} +2}{3} }\:or\: {\sf\boxed{\sf x=\frac{2-\sqrt{217} }{3} } }}[/tex]

Step-by-step explanation:

[tex]\boxed{\sf Quadratic \:equation}[/tex]

*All equations of the form ax^2+bx+c=0 can be solved using the Quadratic Formula. *

[tex]\boxed{\sf \square \: \:\frac{-b\pm \sqrt{b^2-4ac}}{2a}}[/tex]

The Quadratic Formula gives two solutions, one when ± is addition and one when its subtraction.

________________________________

[tex]\boxed{\sf 3x^2-4x-71=0}[/tex]

This equation here is in the standard form: ax^2+bx+c=0.

Substitute 3 → a, -4 → b, -71 → c.

[tex]\sf x=\cfrac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4\times \:3\left(-71\right)}}{2\times \:3}[/tex]

→ Square -4, and then multiply -4 × 3= :

[tex]x=\cfrac{-(-4)\pm \sqrt{16+12(-71)} }{2\times 3}[/tex]

Multiply -12 × -71 = 868, then Add 16+852= 868

[tex]\sf x=\cfrac{-(-4)\pm 2\sqrt{217} }{2\times 3}[/tex]

Take the Square root of 868 2√(217).

* the opposite of -4 → 4.

[tex]\sf x=\cfrac{4\pm 2\sqrt{217} }{2\times 3}[/tex]

Multiply 2 × 3 = 6

[tex]\sf x=\cfrac{4\pm 2\sqrt{217} }{6}[/tex]

Now, we'll solve the equation when ± is plus.

→ Add 4+ 2√(217).

→ Divide 4+ 2√(217 ) by 6.

[tex]\boxed{\sf x=\frac{\sqrt{217} +2}{3} }[/tex]

Now, we'll solve the equation when ± is minus.

→ Subtract 2√(217) from 4.

→ Divide 4 - 2√(217) by 6.

[tex]\boxed{\sf x=\frac{2-\sqrt{217} }{3} }[/tex]

Isolate x by dividing each term by the coefficient

Answer:

The answer is b: 25

Note however that the shape of the diagram does not match the numbers on it.  So either it is poorly drawn, or I am misinterpreting the numbers.  It seems pretty clear though that the image is incorrect, as the two segments both marked as being 25 units long are represented at different lengths.

Step-by-step explanation:

The image here does not fit the numbers.  Note that the bottom triangle has two sides with given lengths of 25 units, but they are drawn as different lengths.

Let's plough on though, and find a better image of what that shape would be.

Starting with the bottom triangle:

Given that the two sides of the bottom triangle are both 25 units in length, we know that it is an isosceles triangle (despite its depiction otherwise).  Because of that, we know that the two bottom angles are equal.  We already know that the top corner is 90°, and that the sum of the angles in a triangle must be 180°  This means that the two bottom angles (again, contrary to how its drawn) are both equal to 45°

Now that we have that information, we can look at the over triangle.  We know that the bottom right corner is 45°, and that the bottom left is 90°.  That tells us that the top angle is also 45°.

With that said, we can redraw the image with the proper proportions.  See the attached image.

That very much simplifies things.  The line separating the triangles bisects the hypotenuse of the larger triangle, meaning that x is also equal to 25.

To be sure of that though, we can prove it another way.  Given that the bottom two corners are both 45, we can use the sine rule to measure x.  The sine rule states that the sine of each angle in a triangle has the same ratio to their opposite sides.  Usually expressed as:

[tex]\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}[/tex]

where a, b and c are the side lengths, and A, B and C are the angles of the corners opposite those sides.

With that we can take the two parts of the overall triangle's hypotenuse, 25 and x, and say that each of those divided by the sine of the angle opposite them is equal to each other:

[tex]\frac{x}{\sin 45} = \frac{25}{\sin 45}[/tex]

This turns out to be very easy to solve, as both sides have the same denominator.  As a result, we can just multiply both sides by sin 45, giving us:

x = 25.

dimension by a scale factor of one-third.
The area of the original triangle is
162 cm². What was the original length of
the base?

Answers

Answer:

L = 36

Step-by-step explanation:

"A triangle with a height of 3 cm and a base  of x cm is the result of reducing each  dimension by a scale factor of one-third"

We are looking for the original. This triangle was reduced by 1/3, so we would have to mulitply by 3 to get the original triangle measurements.

height = 3 x 3 = 9

length = x * 3

"The area of the original triangle is  162 cm²."

Area = Base x Height/2

162 = (x*3) * 9/2

324 = (x*3)*9

36 = x*3

x = 12

What was the original length of  the base?"

Length = x * 3

            = 12 * 3

Length = 36
