. Megan is standing 300ft from the Eiffel Tower. The Eiffel Tower is 900 ft tall.
What is Megan's angle of elevation if she looks at the top of the tower?

Answer:

8111.5

Step-by-step explanation:

Deduct for thousand eleven hundred and a half from twelve thousand twelve hundred and twelve

Rewriting the above question in figure :

4000 + 100 + 0.5 = 5100.5

12000 + 1200 + 12 = 13212

13212 - 5100.5 = 8111.5

= 8111.5

Answer:

25 degrees

Step-by-step explanation:

The angle is acute so it is smaller than 90 degrees so it's 25 degrees.

Answer:

The correct answer is C. 1/10.

Step-by-step explanation:

Given that a spinner has 10 equal sections numbered 1 through 10, to determine what is the probability of landing on the 6, the following calculation must be performed:

6 = 1 side only

10 = 10 options

1/10 = X

Therefore, the probability of the spinner landing on the 6 is 1/10.

Answer:

the smallest circle one

center => (0,1)

radius = √3 = 1.73

Graph C  best represents the equation x² + (y-1)²=3². The given equation is compared by the standard equation to form a graph.

If a circle O has a radius of r units and its center is at (h, k) in the coordinate plane, then its equation is:

(x-h)^2 + (y-k)^2 = r^2

The given data equation is;

x² + (y-1)²=3²

Compare the standard equation with the given equation, we get;

h=0

Answer:

[tex]\huge\boxed{\sf h = 26.684\ feet}[/tex]

Step-by-step explanation:

See the attached file along with the solution.

Let the height be h,

base of triangle 1 be x

base of triangle 2 be 100 - x

Using the following trigonometry for both the triangles.

[tex]\displaystyle tan (\theta) = \frac{opposite}{adjacent}[/tex]

For triangle 1:

tan 20 = h / x    ---------------------(1)

For triangle 2:

tan 45 = h / 100 - x  -----------------(2)

Taking Eq. (1)

tan 20 = h / x

Multiply both sides by x

tan 20 * x = h

h = tan (20) * x

h = 0.36397x   -----------------------(3)

Put Eq. (3) in (2)

tan (45) = 0.36397x / 100-x

1 = 0.36397 x / 100 - x

Multiply both sides by 100 - x

100 - x = 0.36397 x

Add x to both sides

100 = 0.36397 x + x

100 = 1.36397 x

Divide both sides by 1.36397

100 / 1.36397 = x

73.315 = x

x = 73.315 feet

Now, Finding h (height):

tan 20 = h / x (Eq. (1))

h = tan (20) * x

h = 0.36397 * 73.315

h = 26.684 feet

Answer:

a.) The classes are successful

b.) The classes might not be successful.

c.) Type 11 error

d.) Yes

E.) No

Step-by-step explanation:

C.)

This means that we failed to reject H0 when it is actually FALSE and in fact the classes are successful , that means mean μ > 100, that is: null hypothesis is False.

D.)

Type 1 error occurs when we incorrectly reject H0 ; that is we rejected H0, when it is true

Here, H0, means the classes aren't successful, hence, incorrectly rejecting H0 means we have committed a type 1 error

E.)

Type 11 error means failing to reject H0

;

Here, H0, means the classes aren't successful,

Hence, if we fail to reject H0 in this scenario, we are right, hence, there is no possibility of making a type 11 error in this scenario

The answer is "ski slope from left to right".

Step-by-step explanation:

It has been shown by the jeweler's value in the standardized residuals, it is clear that a linear relation is not fulfilled between mass and market price.

And you know that a normality test would be violated if a curve exists upon on remainder of a story. Because the constant variance will not be received. That violated the static hypothesis.

There B, C, D, E does have the consistent variance as seen in the figure following the linear hypothesis of equal variances however the curvature is shown by a residual plot that has not fulfilled requirements, but the direct correlation between mass and current value is not fulfilled.

I HOPE IT'S HELP PLZ FOLLOWING ME

Since the shape is a square pyramid, the base would be 14 by 14. The area of one triangle would be 10 times 14 times 1/2 = 70. 70 times 4 = 280. 14 times 14 = 196

196 + 280 = 476

Final answer = 476

this is the correct answer

The number of full cones of water needed to completely fill the cylinder with water is 8 cones.

The Volume of Cylinder is, V= πr²h

where r is the radius, h is the Height of cylinder.

Given:

Cylinder:

Height= 6

Radius = 4

Volume of cylinder = πr²h

                                = πx 4 x 4 x 6

                                = 96π in³

and, Cone:

Radius = 3

l = 5

h= √5²-3²

h = √25-9

h= √16

h= 4 inch

So, Volume of Cone = 1/3 πr²h

                                  = 1/3 x π x 3 x 3 x 4

                                  =  12π in³

Thus, number of full cones of water needed to completely fill the cylinder with water

= 96π in³/ 12 π in³

= 8 cones

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.

Step-by-step explanation:

Slope = delta y/delta x

[tex]slope = \frac{y_1-y_2}{x_1-x_2}[/tex]

Slope = (-3-3)/(1-2)

Slope = -6/-1

Slope = 6

Answer:

6

Step-by-step explanation:

Given :-

And we need to find the slope of the line passing through the two points . The slope of the line passing through two points is the difference of y coordinates divided by difference of x coordinates.

Substituting the respective values :-

[tex]:\implies[/tex] m = y₁ - y₂/ x₁ - x ₂

[tex]:\implies[/tex] m = -3 -3 / 1 - 2

[tex]:\implies[/tex] m = -6/-1

x = 11

Step-by-step explanation:

Given the expression;

5x+2y=67 ...1

x=3y−7 ....2

Substitute 2 into 1

5(3y-7)+2y = 67

15y - 35 + 2y = 67

17y = 67+35

17y = 102

y = 102/17

y =6

Recall that x = 3y - 7

x = 3(6) - 7

x = 18 - 7

x = 11

Hence the value of x is 11

Answer:

see below

Step-by-step explanation:

3.3 × 10^2  light years

one light year is 5.9 × 10^12 miles

you need to multiple these two values

3.3 × 10^2  light years  ×  5.9 × 10^12 miles/light year =

=     (3.3 × 5.9) × 10^2 × 10^12
