Answer:

-8

Step-by-step explanation:

Multiply the brackets (2x - 4)

Add the x constant together (4x + 2x - 4x - x)

Add the other numbers together (4-12)

x = -8

Have a good day :)

Beach ball has a diameter of 10 in what is the volume of air contained inside the beach ball
kicyunya [14]
The formula for volume of a sphere is \frac{4}{3}  \pi r^{3}
To get radius from diameter, we must divide it by 2. 10/2=5, meaning the radius is 5 in.
Now, we just need to plug the values into the equation.
\frac{4}{3}  \pi 5^{3} =  \frac{4}{3}  \pi 125 = 166.67 \pi = 523.61 in^{3}

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3
Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

  • EFJL is dilation of ABIK
  • AB has a length of 12
  • EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25

Can anyone please help with these 2 questions. If you can, please show step-by-step.
valentinak56 [21]

Answer:

1. x = 21

2. m∡ABC =  51°

Step-by-step explanation:

First problem, solve for x

the sum of inside angles of a triangle is 180

also the supplementary angle for L = 180 - 100 is 80°

now you can add all angles

80 + 2x - 11 + 2x + 27 = 180

4x + 96 = 180

4x = 84

x = 21

Second problem, solve for m∡ABC

the sum of inside angles of a triangle is 180

also the supplementary angle for C = 180 - 148 is 32°

now you can add all angles

31 + 2x - 15 + x - 5 = 180

3x + 12 = 180

3x = 168

x= 56,

now solve for  m∡ABC = (x - 5)° = (56 - 5)° = 51°
