The radius of a circle is 12.8m. Find the circumference to the nearest tenth

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

Answer:

3/7 is equal to 12/28

Step-by-step explanation:

n equals 12 because 28 divided by 7 is 4. multiply 3 by 4 and get 12.

Answer:

n=12

Step-by-step explanation:

Because 28 divided by 7= 4 so you have to do the same on the top and 3*4=12

Answer:

x=5.09

Step-by-step explanation:

Always look at what info they give you, here you have angle, opposite, and adjacent.  The trig function that uses [tex]\frac{opp}{adj}[/tex] is tangent so tan (27) = [tex]\frac{x}{10}[/tex] so

x = 10 tan (27) so x = 10 (.5095254495) [make sure you are in degree mode] so x has to be 5.09

The same goes for question 10, check what you are given [hint: you will need sin probably]....good luck!

Answer:

x=1   y=5

Step-by-step explanation:

plug y = 4x+1 into the second equation, so

3x+2(4x+1)=13 and solve

3x+8x+2=13

11x+2=13

11x+2-2=13-2

11x=11

x=1

then plug x=1 into the first equation

y=4(1)+1

y=4+1

y=5

The angles x°, 2x°, and (x + 10)° are complementary angles. Then the value of the variable x will be 20°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

The angles x°, 2x°, and (x + 10)° are complementary angles.

Then the sum of the angles x°, 2x°, and (x + 10)° will be 90°.

Then the equation will be

x° + 2x° + (x + 10)° = 90°

Simplify the equation, then the value of x will be

4x + 10 = 90

      4x = 80

        x = 20°

Thus, the value of the variable x will be 20°.

Step-by-step explanation:

its a fraction

Answer:

True

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5.2%/100 = 0.052 per year,

then, solving our equation

I = 10000 × 0.052 × 5 = 2600

I = $ 2,600.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 5.2% per year

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

                    1/3+a-(5/4*a)=0

                 5

Simplify   —

                 4

    1                 5

 ( — +  a ) -  ( — • a )  = 0

   3                 4

                 1

Simplify   —

                 3

Solve  :    -3a+4 = 0

Subtract  4  from both sides of the equation :

                     -3a = -4

Multiply both sides of the equation by (-1) :  3a = 4

Divide both sides of the equation by 3:

                    a = 4/3 = 1.333

Answer:

Cost of Senior Citizen Ticket: $15

Cost of Student Ticket: $3

Step-by-step explanation:

Let the price of a senior citizen ticket be s.

Let the price of a student ticket be t.

Day 1:

s + 12t = 51

Day 2:

5s + 6t = 93

The system of equations is:

s + 12t = 51

5s + 6t = 93

Let's use the substitution method to solve it. Solve the first equation for s.

s = 51 - 12t

Now substitute s in the second equation with 51 - 12t.

5s + 6t = 93

5(51 - 12t) + 6t = 93

255 - 60t + 6t = 93

Subtract 255 from both sides. Combine -60t and 6t.

-54t = -162

Divide both sides by -54.

t = 3

Now substitute 3 for t in the equation

s = 51 - 12t

s = 51 - 12(3)

s = 51 - 36

s = 15

The number of medium bags will be 410 / 3.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags

The equation can be written as,

L + M + S = 440

L = 2M

2M + M + 30 = 440

3M = 410

M = 410 / 3

Therefore, the number of medium bags will be 410 / 3.
