Answer:

? = [tex]tan^{-1}[/tex](11/24)

**PUT  [tex]tan^{-1}[/tex](11/24) INTO CALCULATOR

Step-by-step explanation:

1. tan(?)=11/24

--> 11/24: SOH, CAH, TOA: sin(x)=opposite side of the x/hypotenuse, cos=adjacent side of the x/hypotenuse, tan=opposite side of the x/adjacent side

2. to get ? of tan you can't divide tangent, you have to do the inverse function, which is [tex]tan^{-1}[/tex], and put it into the calculator

Answer:

2:4

or in simplest form, 1:2

Step-by-step explanation:

Answer:

2:4

Step-by-step explanation:

As the question said "what is the simplest ratio of triangles to circles?" . You have to write triangles : circles . But in the beginning of the question it said "2 triangles and 4 circles" so we have to use numbers instead of words. That why the answer is 2:4.

Answer:

I = $ 480.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 4000 × 0.06 × 2 = 480

I = $ 480.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 6% per year

for 2 years is $ 480.00.

Answer:

I think it's D cause it says less than 3 and all possible ways, so that's the only one that makes sense to me.

Answer:

Below where atleast put a picture then ill answer

Answer: Less

Step-by-step explanation: Ok lets make them both have a common denominator. This is 36. So 1/4 is going to be 9/36 and 3/9 is going to be 12/36

Answer:

1/4 is less than 3/9.

Step-by-step explanation:

Take these fractions into decimal format.

1/4 = 0.25

3/9 = 0.33.

From this, 0.25 < 0.33

So, 1/4 < 3/9, or 1/4 is less than 3/9.

Answer:

x = 14

Step-by-step explanation:

We need to solve the given expression.

[tex]\sqrt{x+2}+4=0[/tex]

Subtract 4 from both sides,

[tex]\sqrt{x+2}+4-4=-4\\\\\sqrt{x+2}=-4[/tex]

Squaring both sides,

[tex](\sqrt{x+2})^2=(-4)^2\\\\(x+2)=16\\\\x=16-2\\\\x=14[/tex]

So, the value of x is equal to 14.

Answer:

Rectangle and Parallelogram

Step-by-step explanation:

Quadrilaterals are closed figures with four sides. Examples are: square, rectangle, parallelogram etc.

In the given question,

i. one of the parallelograms would be a rectangle since it has 4 right angles and two pairs of parallel lines.

ii. the other would be a parallelogram since it has two pairs of parallel lines and angles are not right angles.

The two quadrilaterals would be rectangle and parallelogram.

Answer:

D) 546 cubes

Step-by-step explanation:

Base: 2 1/6 x 1 1/6 =

13/6 x 7/6 =

91/6

This means 91 cubes that are 1/6 for the base.

91x6=546

Answer: 42

Step-by-step explanation:

Hi there!

[tex]\large\boxed{f(-6) = 8}[/tex]

f(x) = -x + 2

Find f(-6) by substituting -6 for x:

f(-6) = -(-6) + 2

Simplify:

f(-6) = 6 + 2

f(-6) = 8

12: 8

Step-by-step explanation:

Answer:

~1.29 inches

Step-by-step explanation:

C = 2πr

C = 3r + 4.25

2πr = 3r + 4.25

2πr - 3r = 4.25

r(2π-3) = 4.25

r = 4.25/(2π-3) ≈ 1.29

Answer:

- September

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

[tex]T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

[tex]T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]

[tex]55 = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]

[tex]27\cos{((\frac{\pi}{6})(m-6))} = 10[/tex]

[tex]\cos{((\frac{\pi}{6})(m-6))} = \frac{10}{27}[/tex]

Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.

[tex]\cos^{-1}{\cos{(\frac{\pi}{6})(m-6)}} = \cos^{-1}{\frac{10}{27}}[/tex]

Now, with the help of a calculator, in radians:

[tex]\frac{\pi}{6}(m-6) = 1.19[/tex]

[tex]\pi m - 6\pi = 6*1.19[/tex]

[tex]\pi m = 6*1.19 + 6 \pi[/tex]

[tex]m = \frac{6*1.19 + 6 \pi}{\pi}[/tex]

[tex]m = 8.27[/tex]

8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.

Answer: September

Edge

Answer:

1.7$

Step-by-step explanation:

Given

original price = $2.87

New price = $2.82

Percentage decrease = original price-New price/New price × 100

Percentage decrease = 2.87-2.82/2.87× 100

Percentage decrease = 0.05/2.87 × 100

Percentage decrease = 5/2.87

Percentage decrease = 1.7%

Answer:

A radius is the distance from the circle's middle to its perimeter, which is known as its circumference. The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3.
