Answer:

x = 65

Step-by-step explanation:

all angles in a triangle add up to 180 degrees

therefore, knowing that we can say that 25 + 25 = 50 degrees.

we then minus 50 from 180 (180-50=130) to find the remaining angle

we then say that 2x = 130

and solve for x i.e. 130/2 = 65

therefore x is 65

Answer:

b= 7

Step-by-step explanation:

24= 3b + 3

24-3 = 3b

21= 3b

21/3 = b

7 = b

Answer:

Step-by-step explanation:

56(cos(33) + i sin(33)) = 7(cos(11°) + i sin(11°))

Divide both sides by 7 to get;

8(cos(33) + i sin(33)) = (cos(11°) + i sin(11°))

Expanding and Rearranging gives;

8cos(33) + 8i sin(33)) - cos(11) - isin(11)

This gives ;

8Cos(22) + 8i sin(22) = 8(Cos(22) + I sin(22)

Answer:

Step-by-step explanation:

The vertical height as a function of time for some initial velocity v and some launch angle α is ...

  h = (-16t +v·sin(α))t

This will be zero (the ball hits the ground) at ...

  t = v·sin(α)/16

__

The horizontal distance as a function of time is then ...

  x = v ·cos(α)t

Where t is given from the height equation, the horizontal distance to the point where the ball hits the ground is ...

  x = v·cos(α)·v·sin(α)/16 = v²·sin(2α)/32

For an angle of 31°, the ball will travel ...

  (80 ft/s)²·sin(62°)/(32 ft/s²) = (200 ft)·sin(62°) ≈ 176.6 ft . . . at 31° angle

For an angle of 49°, the ball will travel ...

  (200 ft)·sin(98°) ≈ 198.1 ft . . . at 49° angle

Answer:

3/10 of people vacationed in another state.

Step-by-step explanation:

Because there are 60 people in total, the denominator has to be 60. The numerator then is going to be the amount of people that vacationed in another state. Simplify that fraction by 6, and you will get 3/10 as your answer.

Answer:

[tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Since we want a fraction, we find the total number of people who vaccinated, then we find how many people vacationed in another state.

18+10+5+15+12=60, and 18 people vacationed in another state, we get

[tex]\frac{18}{60}[/tex], and we can divide top and bottom by 2, we simplify to [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Oatmeal is packaged in a right circular cylindrical container that has a radius of 1.5 inches and a height of 12 inches. What is the surface area of this container in terms of π?

The formula for the surface Area of a cylinder = 2πr( r + h)

r = 1.5 inches

h = 12 inches

Hence,

2 × π × 1.5( 1.5 + 12)

3π(13.5)

= 40.5π square inches

The surface area of the cylinder is

= 40.5π square inches

Answer:

2x 2 x 2 x 2= 8 + 1 = 9?

Step-by-step explanation:

The solution of the equation 2x + 1 = 9 will be 4.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The equation is given below.

2x + 1 = 9

Simplify the equation, then we have

2x + 1 = 1

2x = 9 - 1

2x = 8

x = 8 / 2

x = 4

The solution of the equation 2x + 1 = 9 will be 4.

Step-by-step explanation:

Answer:

Width = 6ft Area = 54 sq ft

Step-by-step explanation:

First, re-read the problem until you understand it and can put it into your own words.  I re-wrote it like this:  "Find the area of a rectangle by first finding the length (L) and the width (W)."   [note that I added "find L and W," but that is how I'm going to solve the problem;  I could also have said that we will need the formulas, P=2L+2W and A=LW, but you knew that already, right?).

Translate the problem:

 "The length of a rectangle is 3 ft longer than its width"      means

         L                             =    3             +         W                 (eq1)

 "the perimeter of the rectangle is 30 ft"     means

            P                                = 30                      (eq2)

So, now the math is easy, just find L and W so we can compute the area:

     P = 30 = 2L + 2W                         (eq3; from eq2 and the formula for P)

          30 = 2(3+W)  +  2W              (use eq1 to substitute for L)

          30 = 6 + 2W   + 2W              (distribute)

           30 = 6 + 4W                       (collect terms)

            24 = 4W                        (subtract 6 from both sides)

            6 ft = W                         (divide both sides by 4)

Use the easiest equation (either eq1 or else eq3) to find L:

          L = 3 + W        (eq1)

          L = 3 + 6

          L = 9 ft

What is the area (A)?

          A = L*W

          A = (9 ft)*(6 ft)

          A = 54 sq ft

Answer:

I believe the two numbers are 14 and 24

Answer:

Those numbers are 14 and 24.

Step-by-step explanation:

You can solve this pretty quickly by taking those two facts and combining them:

a + b = 38

a - b = 10

Let's solve the second one for a:

a = 10 + b

Now we can substitute that into the first one:

a + b = 38

(10 + b) + b = 38

2b + 10 = 38

2b = 28

b = 14

To find a, we can plug that back into one of the original equations:

a + b = 38

a + 14 = 38

a = 24

We can also test our answer by plugging the results into the other given equation and see if we get the same value:

a - b = 10

24 - 14 = 10

10 = 10

So we know our answer is correct.
