Answer:

Step-by-step explanation:

I think what they are asking is to subtract the 3 tokens from 21 tokens he already has giving us 18. and since it says "Twice the number of tokens" I'm assuming you divide 2 from 18 giving you 9 tokens.

A circle with area 36π has a sector with a central angle of 11/6π radians. What is the area of the sector?

bazaltina [42]

Answer:

33pi or 103.62 squre units

Step-by-step explanation:

$central \: angle \: ( \theta) \\ = \frac{11}{6} {\pi}^{c} = \frac{11}{6} \times 180 \degree = 330 \degree \\ \\ area \: of \: sector \\ = \frac{ \theta}{360 \degree} \times area \: of \: circle \\ \\ = \frac{ 330 \degree}{360 \degree} \times 36 \: \pi \\ \\ = \frac{ 330 }{10 } \pi \\ \\ = \red{ \bold{33\pi}} \: {units}^{2} \\ = 33 \times 3.14 \\ = 103.62 \: {units}^{2} \\$

The sum of two numbers is 58. The first number is 8 less than half the second number. Let c represent the first number. Let d re

alexandr1967 [171]

Answer: A ,C,G and H are correct statements. Look into the step by step for more understanding.

Step-by-step explanation:

To solve for this problem let's find the actually numbers.

so we know that c + d=58 and also c= 1/2d-8

We have two systems of equations

c+d = 58

c= 1/2d - 8

Solve for c by substitution. Substitute the second equation into the first one.

1/2d -8 + d = 58 Add 8 to both sides

1/2 +d = 66

3/2d =66 Divide both sides by 3/2

d=44 Now we know the d which is the second number is 44 so subtract it from 58 to find the first number.

58 - 44 = 14

we will represent the statements by letters from A going.

A. The equation c + d = 58 represents the sum of the two numbers

B. The equation c+d=58 represents the sentence "The first number is 8 less than half the second number."

C.The equation c= 1/2d -8 represents the relationship between the two numbers.

D. The equation c= 1/2d - 8 represents the sum of the two numbers.

E. The number d is 14.

F. The number c is 44.

G. The number c is 14.

H. The number d is 44.

Now looking at the statements, A ,C,G and H are all correct.

The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below:

topjm [15]

Basic facts of trigonometry

sine, cosine, and tangent will give you the proportion of the sides of a right triangle in relation to an angle

sin x = opposite side/ hypotenuse
cosx= adjacent side/ hypotenuse
tan x= opposite side/ adjacent side

x is our angle
hypothenuse is the longest side of the right triangle

a good way to memorize this is SOH CAH TOA

now since your picture is not given, I will make some assumptions, such as the hypothenuse is the distance from the sun to the moon.

since you want to find the distance from the earth to the sun, and you know the distance from the earth to the moon, this means on a right triangle, you're trying to find the relationship between the adjacent, opposite side, and an angle

which means you will want to use tan x= opposite side/adjacent

now, i cant go any further because the location of the angle is important in the explanation, but short answer,

sin,cos,tan of an angle will give a proportion of the sides. if you know the measurement of a side, you can use this proportion in order to determine the corresponding measurement of the other side

How do I do this I am struggling with solving process

solmaris [256]

As far as 2) check the picture below, solve for "x"

what's the angle "3m"? well, 3m = 12x + 40, those two angles are equal, since it's an isosceles trapezoid
