Answer: About 84.261 degrees

Step-by-step explanation:

To find the angle of elevation, we can create a triangle and solve for the angle.

First, we can imagine a triangle with side A being the ground between the base of the ladder and the wall, side B being the wall (from the base of the wall to where it touches the top of the ladder), and side C being the ladder (from where it touches the ground to where it touches the wall).

In the problem, it has already given us two of the side lengths we need to solve for the angle of elevation:

1. We know that the ladder is 10 feet tall, so we can say that side C is 10.

2. We know that the ladder base is placed 1 foot from the wall, so we can say that side A is 1.

The angle of elevation is the angle that the ladder is tilted from the ground, or the angle between the ground (side A) and the ladder (side C). These sides relative to the angle would be the adjacent (side A) and the hypotenuse (side C).

To calculate for the angle, we can use the cosine function. (cos = adjacent / hypotenuse)

To find the angle of elevation (which we can call angle b), we can use:

cos(b) = A / C

arccos(A / C) = b

(Note: arccos is the inverse of the cos function)

Then, we can plug in the values and get:

b = arccos(1 / 10)

b = 1.471 radians OR 84.261 degrees

Answer:

B

Step-by-step explanation:

just plug it in. (also just means divide it out)

 f(x) = 11 - x is the same graph as:..... x + y = 11

Answer:

Simplify 32(x^2+4x)

32x^2+128x=16(x^2+4x+3)

simplify 16(x^2+4x+3)

32x^2+128x=16x^2+64x+48

subtract 16x^2 from both sides

subtract 64x from both sides

subtract 16x^2 and 32x^2

subtract 64x from 128x

x=−2+√7,−2−√7 answer

hope this helps :))

Answer:

the probablity of rolling a one is 1/6

Step-by-step explanation:

Answer:

one-in-six probability

Step-by-step explanation:

Say, you do roll that die. You have no clue what it's going to land on because each number has a one-in-six chance of being rolled. Therefore, the probability of rolling a one on a six-sided die is one-in-six

Answer:

There are 240 variations

Step-by-step explanation:

On one pizza, there are 3 types of toppings, and different variations for each. In order to figure out how many total variations there are, you need to multiply each variation by the other:

5 types of cheese x 6 types of vegetables x 8 types of meat

= 240 variations of the pizza

Answer:

Step-by-step explanation:

Simplifying

3x + 3y = -18

Solving

3x + 3y = -18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

3x + 3y + -3y = -18 + -3y

Combine like terms: 3y + -3y = 0

3x + 0 = -18 + -3y

3x = -18 + -3y

Divide each side by '3'.

x = -6 + -1y

Simplifying

x = -6 + -1y

//////////////

Simplifying

2x + -4y = -6

Solving

2x + -4y = -6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

2x + -4y + 4y = -6 + 4y

Combine like terms: -4y + 4y = 0

2x + 0 = -6 + 4y

2x = -6 + 4y

Divide each side by '2'.

x = -3 + 2y

Simplifying

x = -3 + 2y

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.

Bottom answer

Step-by-step explanation:

Although I cannot see the answer labels, the answer is the very bottom graph.  The way you can find a functional graph is if you add vertical lines going down and that there is only one point that crosses it, not two.  It is kind of difficult for me to explain, so if you need help, I suggest you look up how to know when a graph is a function or not.

Answer:

74.9 degrees

Step-by-step explanation:

All angles in a triangle must add up to 180 degrees. Add 29.1 and 76 to get 105.1, and then you can subtract that from 180 to get 74.9.

Answer:

10 percent

Step-by-step explanation:

t=ratio

5x:45x

total=45x+5x=50x

5x/50x=1/10=10 percent

You need $4840 money for the loan.

Through addition, objects are combined and counted as a single large group. The process of adding two or more numbers together is known as addition in mathematics. The terms "addends" and "sum" refer to the numbers that are added and the result of the operation, respectively.

According to the question,

Spending amount =$5000

Down payment = $500

Taxes amount = $340

The total loan amount :

= Spending amount - down payment + Taxes amount

By substituting the above values, we get

= $5000 - $500 + $340

= $4840

Therefore, the loan amount is $4840.

Given:

The graph of a figure and its image after dilation.

To find:

The scale factor.

Solution:

From the given graph it is clear that

ND = 3 units

N'D' = 6 units.

We know that,

[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of original figure}}[/tex]

[tex]\text{Scale factor}=\dfrac{N'D'}{ND}[/tex]

[tex]\text{Scale factor}=\dfrac{6}{3}[/tex]

[tex]\text{Scale factor}=2[/tex]

Therefore, the scale factor is 2 and the correct option is A.

Answer:

$3255.56

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

P = 586 / ( 0.03 × 6 ) = 3255.5555555556

P = $ 3,255.56

The principal required to

accumulate interest of $ 586.00

on a rate of 3% per year for 6 years is $ 3,255.56.

Answer:

1/18

Step-by-step explanation:

Answer:

1/18

Step-by-step explanation:

When dividing a fraction with another number or fraction you always do the reciprocal of the second number and it turns into multiplication.

so it'll look like this:  [tex]\frac{1}{9} *\frac{1}{2}[/tex]

then you just multiply straight across to get 1/18 because 1*1 is still 1 and 9*2 is 18
