Please help this is the last question and i don’t understand

Mathematics

tiny-mole [99]3 years ago

Answer: 30

Step-by-step explanation:

The angles of triangles have to add up to 180°

So:

x + x + 70 + x + 20 = 180

Bring like terms together

x + x + x + 70 + 20 = 180

3x + 90 = 180

Subtract 90 from both sides

3x = 90

Divide both sides by 3

x = 30

Find the value of arc s
Svetlanka [38]

Answer:

≈ 38.64 units

Step-by-step explanation:

The length of arc s is calculated as

circumference of circle × fraction of circle

The central angle subtended by arc s is 360° - 114° = 246° then

arc s = 2πr × \frac{246}{360}

        = 2π × 9 × \frac{41}{60}

        = 18π × \frac{41}{60}

        ≈ 38.64 ( to 2 dec. places )

PLEASE HELP!!!
labwork [276]

Answer:

The correct options are:

So, these functions have the same range.

The functions have the same base.

The functions have the same domain.

g(x) is a translation left 1 unit.

Step-by-step explanation:

According to the table, both are exponential functions.

We have that

f(x) = 3^{x}

g(x) = 3^{x+1}

Lets see each affirmation:

The functions have the same base.

An exponential function a^{x} has base a.

In this problems, both f and g have base 3.

The functions have the same range.

The range of f are all the values that f can assume. That is, all the positive numbers.

The range of g are all the values that g can assume. That is, also all the positive numbers.

So, these functions have the same range.

The functions have the same exponent.

An exponential function a^{x} has exponent x.

f has exponent x and g has exponent x + 1. So those functions do not have the same exponent.

The functions have the same domain.

Yes, they both have x = {0,1,2,3} as domain.

g(x) is a translation left 1 unit.

g(x) = f(x+1). So yes, g(x) is a translation left 1 unit.

g(x) is a translation right 2 units.

g(x) is not f(x-2). So g(x) is not a translation right 2 units.

g(x) is a translation up 2 units.

g(x) is not f(x) + 2. So g(x) is not a translation up 2 units.

The diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
AURORKA [14]

Answer:

25.1 ft

Step-by-step explanation:

To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).

So essentially, apply to your calculator:

2(3.14)4=25.12

pretty simple! hope this helps!

has tables that seat 6 people each.all the tables and chairs have 4 legs each.altogether there are 364 furniture legs.if there i
Fed [463]

Answer: 91 guests

Step-by-step explanation:

Given the available furniture legs to be 364, where each seat has 4 legs

We will divide 364 by 4 to get the number of available seats.

364/4 = 91 seats

If 91 seats are available and it is set at 1 seat per guest,

Number of guests will be 91 seats/1 = 91, therefore, 91 guests will be available.
