Answer:

To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.

sin x = O/H

cos x = A/H

tan x = O/A

where O stands for opposite, A for adjacent, and H for hypotenuse. So, for example, the sine of x is equal to the side opposite of angle x over the hypotenuse. The same goes for cosine and tangent. Using the diagram attached, we have the expressions of the trigonometric functions as shown below.

sin x = f/d

cos x = e/d

tan x = f/e

14. Team 8A is selling snacks at the football game to raise money for a field trip. They are selling popcorn for $2.50 and pretz

Mamont248 [21]

Answer:

40 popcorns and 90 pretzels sold.

============

Let the number of popcorns is x and pretzels is y.

Set up equations:

x + y = 130
2.5x + 2y = 280

Solve by elimination, multiply the first equation by 2 and subtract from the second equation:

2.5x + 2y - 2x - 2y = 280 - 2*130
0.5x = 280 - 260
0.5x = 20
x = 20/0.5
x = 40

Find y:

40 + y = 130
y = 130 - 40
y = 90

Write the equation of the line that passes through the given points (0,2)) and (-9, -3)

Irina18 [472]

Step-by-step explanation:

Y= m x+ C

m (slope ) = 2 - (_3) / 0 _( - 9 )

= 5 / 9

( O, 2 ) Satisfying equation

2= 5/9 ( 0) + C

C= 2

So eq. is

y= 5/ 9 X + 2

(27 thousands 3 hundreds 5 ones) x 10

anyanavicka [17]

Answer:

Two hundred seventy three thousand and fifty .

Step-by-step explanation:

Given : (27 thousands 3 hundreds 5 ones) x 10

Solution:

27 thousands 3 hundreds 5 ones = 27,305

So, $27,305 \times 10$

$273,050$

Periods are counted from last .

The 1st period consists of ones, tens and hundred.

The 2nd period consists of thousand, 10 thousand and 100 thousands.

The 3rd period consists of million, 10 million and 100 million.

So, 273,050 is Two hundred seventy three thousand and fifty

Hence (27 thousands 3 hundreds 5 ones) x 10 is Two hundred seventy three thousand and fifty .
