because its 4/10 but you wanted to simplify it so its 2/5

brainlist? its the crown btw

Answer 2

Answer:

? = 2/5

Step-by-step explanation:

Lets say '?' is 'x'First change 1/2 to 5/10 Now, subtract 9/10 from 5/10. You should get -x = -4/10Now divide the equation by -1 so x=4/104/10 is the same as 2/5, which is the answer

The radius of a circle is 3 m. Find its circumference in terms of pi

Answers

Gotcha, bro.

(I don't know what pi is, so I'm gonna assume that it is 3.14)

C=pi x diameter

First, multiply the radius by 2 so you have the diameter.

3x2=6

Second, multiply 3.14 (pi) by 6 (diameter)

3.14x6=18.84

Therefore, the circumference is 18.84.

(19 if you round it to the whole number)

Hope this helps!

The circumference of the circle is 6π meters.

What is a circle?

A circle is a two dimensional figure with a radius and circumference of 2πr.

We have,

The circumference of a circle is given by the formula:

C = 2πr

where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the radius of the circle is 3 meters.

Substituting this value in the formula, we get:

C = 2πr

C = 2π(3)

C = 6π

Therefore,

The circumference of the circle is 6π meters.

What are the ratios for SIN A and COS A

Answers

Answer:

A

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

Multiple choice answer

Answers

Answer:

C. 9.24

Step-by-step explanation:

x is the height here, looking at the triangle.

To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.

6/cos(57) would equal about 11.0647.

Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.

x = √11.01647² - 6²

x = √121.3626112609 - 36

x = √85.3626112609

x = 9.23918888544335

x ≈ 9.24, so C is the answer.

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?​

Answers

Answer:

10

Step-by-step explanation:

You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9

The height the 15 ft building touches the building is approximately 10 ft.

The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.

The situation forms a right angle triangle.

Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.

Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.

Using trigonometric ratios,

let

∅ = angle

tan ∅ = opposite / adjacent

tan ∅ = 6 / 9 = 2 / 3

∅ = tan⁻¹ 0.6666666

∅ = 33.6900672615

Therefore, the height the 15 ft ladder touch building can be calculated as follows:

tan 33.69 = h / 15

h = 15 × 0.66666496431

h = 9.99997446476

h ≈ 10 ft.
