How in the heck do I do this?​

The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees

To solve for x set all of the expressions of angles equal to 180 and isolate x

11x - 3 + 7x + 5 + 13x - 8 = 180

31x + (- 6 + 6) = 180 + 6

31x/31  = 186 / 31

x = 6

To find the measure of each angle plug 6 into the x into each individual expression

Hope this helped!

A jet moving at constant speed traveled 6,600 km in 3 hours. What was the speed of the jet?
DanielleElmas [232]

Answer:

The speed of the jet is 2,200\frac{km}{h}

Step-by-step explanation:

The speed traveled by the jet can be found using the relationship between distance and time. Because the problem gives the values for distance and time, they must be replaced in the equation and in this way the requested speed will be found.

1. Write the general equation for the speed:

Speed=\frac{Distance}{Time}

2. Replace the values of distance and time on the general equation for the speed and make the mathematical operations:

Speed=\frac{6,600km}{3hours}

Speed=2,200\frac{km}{h}

Therefore the speed of the jet is 2,200\frac{km}{h}

A certain chalkboard manufacturer determines that their largest blackboard model has a mean length of 5.00 m and a standard devi
Igoryamba

Answer:

23 chalkboards

Step-by-step explanation:

Given:

Mean length = 5 m

Standard deviation = 0.01

Number of units ordered = 1000

Now,

The z factor = \frac{\textup{x - Mean}}{\textup{standard deviation}}

or

The z factor = \frac{\textup{4.98 - 5}}{\textup{0.01}}

or

Z = - 2

Now, the Probability P( length < 4.98 )

Also, From z table the p-value = 0.0228

therefore,

P( length < 4.98 ) = 0.0228

Hence, out of 1000 chalkboard ordered (0.0228 × 1000) = 23 chalkboard are likely to have lengths of under 4.98 m.

What is the equation of the given line in the point-slope form
Genrish500 [490]
First using the given two points we can find the slope (m) of the line

Slope = m =  \frac{Rise}{Run} \\  \\ &#10;m= \frac{4-1}{3-0} \\  \\ &#10;m=1

Thus the slope of given line is 1.

Using slope and a point (0,1) we can write the equation in point slope form as

y - 1= 1(x-0)
y - 1 = x

The above equation is the point-slope form of the equation.

Determine if each set of ordered pairs represents a function. <br> (2,3), (6,-5), (-1,3)
docker41 [41]

Answer:

yes

Step-by-step explanation:

You can perform the "line test." If it is a function, there will not be two x's of the same value. In this case, x is 2,6,-1. No number repeats, thus making a function.
