Answer:

71 degrees

Step-by-step explanation:

1. We know that the angle is unknown as demonstrated by '?'

2. The 17 side is opposite of the unknown angle

3. The 18 side the hypotenuse (not in contact with the right angle)

4. Therefore sine will be used where, sine(degree) = opposite/hypotenuse

5. The equation should be sine(degree) = 17/18

6. Since we don't know the degree we bring sine to the left and has a negative power of 1

7. The equation now becomes degree = sine^-1 (17/18)

8. The answer to this is 70.811... which equals 70 degrees and 48 minutes which rounds to the nearest degree of 71

Answer: no of women before they walked in is 8.

Step-by-step explanation:

given data:

ratio of men and women = 3:5

when 2 men and 1 woman walks in = 2:3

solution:

no of women in the theatre before they walked in

men/women= 3/2,

let men =3x............eqn1

women = 2x................eqn2

Total =20

therefore:

[tex]3x+2x=20[/tex]

collect like terms

[tex]5x=20[/tex]

[tex]x=[/tex][tex]\frac{20}{5}[/tex]

[tex]x=4[/tex]

substitute the value gotten for x into equation 1 and 2

[tex]men = 3x= 3(4)=12\\women=2x=2(4)=8[/tex]

Answer:

15w = s

Step-by-step explanation:

When you look at the graph, after one week, Michael has earned 15 dollars. So if you're trying to find the amount for w weeks, you would multiply 15 by w to get s, the amount of money in Michael's account.

Answer:

$1.42

Step-by-step explanation:

The cost of postcard is $0.35 and the cost of large envelope is $1.42.

We have -

We can write -

14x + 5y = 12

10x + 15y = 24.80

Now, solving the equation graphically, we get -

x = 0.35

y = 1.42

Therefore, the cost of postcard is $0.35 and the cost of large envelope is $1.42.

Answer:

8.06

Step-by-step explanation:

Use the Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

The hypotenuse is always the slanted side, or c (x in this picture), but the other numbers can be interchanged. Doesn't matter.

Plug the numbers 4 and 7 into the formula.

[tex]4^{2} +7^{2} =c^{2} \\[/tex]

Now evaluate them to get [tex]c^2[/tex]

16+49=65

To get c, take the square root of 65

[tex]\sqrt{65} = 8.06[/tex]

Step-by-step explanation:

Step 1: Define

2/3(x - 2) = 4x

Step 2: Solve for x

We start with 2/3(x

−

2) = 4r

Distributing the LHS: 2/3x - 4/3 = 4x

subtracting 2/3x from both sides: -4/3 = 10/3x

Multiplying both sides by  3: -4 = 10x

Dividing both sides by  10

: -4/10 = 10x

Then we come up with -2/5.

I think it's the answer anyway:/

Answer:

Step-by-step explanation:

[tex]13x + 14y - 12 = 14x + 15y + 13[/tex]

Collect like terms

[tex]14y-15y=14x-13x+13+12[/tex]

Simplify

[tex]-y =x +25[/tex]

Multiply through by -1(to reverse the inequality)

[tex]-1(-y=x+25)\\\\y =-x-25[/tex]

Answer:

y= -x - 25

Answer:

B = T / 14

Step-by-step explanation:

This scenario can be represented and solved using the following equation...

B = T / 14

In this equation, the variable B represents the total number of boxes required to ship all of the loaves of bread while the variable T represents the total number of loaves of bread. Since each box can only hold 14 loaves of bread, dividing the total by 14 would essentially give us the total number of boxes needed so that all of the loaves of bread are accounted for and placed in boxes.

Answer:

Step-by-step explanation:

here is your answer

x=4 and y=8

Answer:

x = 4

Step-by-step explanation:

3x - 4y = 36

5x + 2y = 8

solve for y:

5x + 2y = 8

-5x           -5x

2y = 8 - 5x

/2        /2

y = 4 - 5/2x

substitute

3x - 4(y) = 36

3x - 4(4 - 5/2x) = 36

3x - 16 + 20/2x = 36

3x - 16 + 10x = 36

13x - 16 = 36

      +16   +16

13x = 52

/13     /13

x = 4
