Explanation:

Line E B C Needs To Equal 180°

Create An Equation

3x + 5 + 3x + 4 + 3x + 9 = 180

Simplify Both Sides Of The Equation

(3x + 3x + 3x) + (5 + 4 + 9) = 180( Combine Like Terms)

9x + 18 = 180

Subtract 18 From Both Sides

9x + 18 − 18 = 180 − 18

9x = 162

Divide Both Sides By 9

9x / 9 = 162 / 9

Nancy bought a soft drink for 2 dollars and 9 candy bars. She spent a total of 38 dollars. How much did each

natima [27]

Answer:

Step-by-step explanation:

Because we know that Nancy bought a drink for 2 dollars, and we are just trying to find the cost of the candy bars, we can subtract 2 dollars from the drink from the total cost:

38 - 2 = 36

Now, the 9 candy bars cost 36 dollars, so to find the individual price of each candy bar, we divide 36 by 9:

36 / 9 = 4

So, each candy bar costs 4 dollars

Hope this helps :)

Jenny reaches the corner to clear away spider webs from the room. She is holding the 5 foot pole at top of head level from 45. S

Slav-nsk [51]

Answer:

Height of ceiling = 9.04ft

Step-by-step explanation:

Given:

Length of pole = 5ft

Horizontal angle = $45^{0}$

Jenny's height = 5ft6in = 5ft + (6/12)ft= 5ft + 0.5ft

Jenny's height = 5.5ft

From the attached diagram, we have that

$sin45^{0}= \frac{b}{5}\\ \\b = sin45^{0}*5=0.7071*5\\\\b=3.5355ft$

b ≅ 3.54ft

Height of ceiling = Height of Jenny + b

Height of ceiling = 5.5ft + 3.54ft

Height of ceiling = 9.04ft

The diameter of a cylinder is 4 centimeters. The height is 12 centimeters. Using 3.14 for pi, what is the volume of the cylinder

erica [24]

Answer:

V = 150.72 cm³.

Step-by-step explanation:

First, get the volume of a cylinder.

V = πr²h

Where:

π = 3.14 (given)

r = radius (half of diameter, or 2)

h = height (12)

Knowing this, substitute the known values.

V = πr²h

V = (3.14)(2²)(12)

Square 2.

V = (3.14)(4)(12)

Multiply 3.14 and 4.

V = (12.56)(12)
Multiply 12.56 and 12.

V = 150.72.

Since it is already rounded to the nearest hundredth, that is your answer.

What is the length of line segment PQ? If you can please explain, thanks.

nydimaria [60]

Given:

Tangent segment MN = 6

External segment NQ = 4

Secant segment NP =x + 4

To find:

The length of line segment PQ.

Solution:

Property of tangent and secant segment:

If a secant and a tangent intersect outside a circle, then the product of the secant segment and external segment is equal to the product of the tangent segment.

$\Rightarrow NQ\times NP = MN^2$
