Answer:

x = 146º

Step-by-step explanation:

Using the Exterior Angle Theorem, you know that x = 54º + 92º.

54º + 92º = 146º, so x = 146º

Fast I need to know what 20/22= x/11

sergij07 [2.7K]

Answer:

To Find => The value of x. in the equation below

$20 \div 22 = x \div 11$

Step-by-step explanation:

We will cross Multiply the digits

=>20 \div 22 = x \div 20

=>We'll cross Multiply

$20 \div 22 = x \div 11 \\ = > 22x = 20 \times 11 \\ = > 22x = 220 \\ = > x = 220 \div 22 \\ = > x = 10$

Hence, 10 is the required answer

Help please. Solve the system of equations using substitution. Show your work in the workspace provided below.

LenKa [72]

Answer:

x=0 y=-11 (0,-11)

Step-by-step explanation:

1. take what y equals (3x-11) and plug it in for y in the second equation

Should look like this: O= 6x-2(3x-11)-22

2. Then distribute O=6x-6x+22-22

3. Then combine like terms O= 0 the 22's cancel out as well as the x's

x= 0

4. plug 0 in for x in the first equation y=3(0)-11

5. y= -11

6. x=0 y=-11 (0,-11)

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 = $\frac{\textup{x - Mean}}{\textup{standard deviation}}$

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

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.
