Answer:

csc theta = 25/7

Step-by-step explanation:

I believe you meant the Greek character theta, not 0.  Note that sin 0 = 0, which is definitely not equal to 7/25.

Rewriting the given info, we obtain:

sin theta = 7/25 find csc theta

The csc function is the reciprocal of the sin function.   Therefore,

if sin theta = 7/25, then csc theta = 25/7

Answer:

z+11y/5 = x

Step-by-step explanation:

Since you are solving for x, you want to isolate the variable. You do that by adding 11y to both sides, which cancels out the -11y. From that you should have z+11y = 5x. To cancel out the 5x you need to divide both sides by 5 to get z+11y/5 = x. Hope this helps :)

Answer:  100f + 150e = 1250

Step-by-step explanation:

Subtract the 1st from the 2nd to solve for e:

50e = 250

e = 5 boxes (# of boxes of eight-once cups)

f + e = 10, so f = 5 boxes: (# of boxes of five-once cups)

6 boxes of 5-ounce cups and 4 boxes of 8-ounce cups could be bought.

Let x represent the number of box of 5-ounce cups and y represent the number of box of 8 ounce cups.

The room can only hold 10 more boxes, hence:

x + y ≤ 10   (1)

A maximum of $1200 is budgeted for yogurt cups. Hence:

100x + 150y ≤ 1200     (2)

Plotting the graph of the inequality, the solution is at (6, 4)

Therefore 6 boxes of 5-ounce cups and 4 boxes of 8-ounce cups could be bought.

Answer:

below in bold

Step-by-step explanation:

f(x) = 2x - 7 - 3

~Combine like terms

f(x) = 2x - 10

When x = 2...

f(x) = 2(2) - 10

f(x) = 4 - 10

f(x) = -6

When x = 3...

f(x) = 2(3) - 10

f(x) = 6 - 10

f(x) = -4

When x = 4...

f(x) = 2(4) - 10

f(x) = 8 - 10

f(x) = -2

x = -27

Step-by-step explanation:

-55 + 4x = 80 + 9x

~Add 55 to both sides

4x = 135 + 9x

~Subtract 9x to both sides

-5x = 135

~Divide 15 to both sides

x = -27

Best of Luck!

Answer:

The required numbers should be changed only by a unit, as proceeding from ten to 1 hundred.

Given that,
To determine how much each number needs to change for a ten for 1 hundred.

A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.

Here,
According to the question,
The number from ten to 1 hundred,

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    y-18-(-3)=0

y-15 = 0  

Add  15  to both sides of the equation :

Answer: 11/3, or 3.66 (repeating)

Step-by-step explanation: 3x + 11, divide 11 by 3, getting a repeating decimal, or a fraction that cannot be simplified

Answer:(3,-4) you just have to follow the equation.

Slope = change in y over change in x.

Slope = (-6 - -9) / (-6 - -2)

Slope = (-6 + 9) / (-6 + 2)

Slope = 3/-4
