The surface area of a cone is about 64 square meters. The radius of base is 2 meters. What is the slant height?

Answers

Answer 1

Answer:

Step-by-step explanation:

L is the slant height

area of base = 4π m²

lateral area = surface area - base area = 64-4π

πrL = 64-4π

L = (64-4π)/(2π) = 8.2 m

Answer:

16 bicycles and 21 tricycles

Step-by-step explanation:Both bicycles and tricycles have 1 set of handlebars. Bicycles have 2 wheels while tricycles have 3.

Using this information, set up a system of equations, where b is the number of bicycles and t is the number of tricycles:

b + t = 37

2b + 3t = 95

Solve by elimination by multiplying the top equation by -2:

-2b - 2t = -74

2b + 3t = 95

t = 21

Then, plug in 21 as t into one of the equations:

b + t = 37

b + 21 = 37

b = 16

So, there are 16 bicycles and 21 tricycles

C. 5x + 11 = 36

Step-by-step explanation:

You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36

Answer:

5x + 11 = 36

Step-by-step explanation:

Looking at the tape diagram, if you count the x, you have 5x and then you have 11. So it would refer to as 5x + 11 and the total of the tape diagram is 36. So it would be :-

5x + 11 = 36

Step-by-step explanation:

Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.

Answers

If y = -x + 2, then substituting this into the first equation lets you solve for x :

x + 4y = 5

x + 4 (-x + 2) = 5

x - 4x + 8 = 5

-3x = -3

x = 1

Now solve for y :

y = -x + 2 = -1 + 2 = 1

So the solution is indeed (x, y ) = (1, 1).

The corporate office building is 50m high and angle of elevation at top of building is 52° when seen from a point on level ground. The distance between point and foot of the building is

Answers

Answer:

39.06 m

Step-by-step explanation:

Given that,

Height of the building, h = 50 m

The angle of elevation at top of building is 52° when seen from a point on level ground.

We need to find the distance between point and foot of the building. Let the distance be d. Using trigonometry to find it. So,

[tex]\tan\theta=\dfrac{P}{B}[/tex]

Where

P is perpendicular

B is base.

So,

[tex]\tan\theta=\dfrac{h}{d}\\\\d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{50}{\tan(52)}\\\\d=39.06\ m[/tex]

So, the distance between point and foot of the building is 39.06 m

Applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.

Recall:

SOH CAH TOA are the common trigonometry ratios that can be used to solve a right triangle.

The information of the building has been sketched in the diagram shown in the image attached below. It shows a right triangle.

The distance between the point on the ground and the foot of the building = x (adjacent)Reference angle (∅) = 52°Opposite side = 50 m

Apply the trigonometry ratio, TOA:

tan ∅ = opposite/adjacent

Substitute

tan 52 = 50/x

x = 50/tan 52

x = 39.1 m

Therefore, applying the trigonometry ratio, TOA, the distance between the point and the foot of the building is: 39.1 m.

Step-by-step explanation:

We need top subtract 5:47 from 1:58 pm.

Since we cannot subtract 5 from 1, we add 12 to the 1:58 hours digit.

1 + 12 = 13

1 pm is 13 hours of the day.
