Answer:

see attached diagram

Step-by-step explanation:

<u>Angle Bisector</u>

The angle bisector bisects the angle into two equal angles.

Measure the angle EDF (I've measured this as 115°)

Divide this by 2: 115 ÷ 2 = 57.5°

Measure an angle of 57.5° from point D on the line DF and draw a line.

<u>Parallel lines</u>

Measure two lines of equal length from points X and Y at an angle of 90° to the line XY. Join the points for the parallel line.

The angle bisector and parallel line are shown in red on the attached diagram.

Answer:

1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass

2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.

Answer:

y2- y1 over

x2 -x2

$- 3 - 0 = - 3$

$0 - 2 = - 2$

Step-by-step explanation:

slope is m =

$m = - \frac{3}{2}$

use the -3 for b and you get

$y = - \frac{3}{2} x - 3$

the ratio of large triangles to small triangles is 2-6 .If there are 100 triangles in the design ,how many small triangles are t

m_a_m_a [10]

Answer:

75 small triangles

Step-by-step explanation:

1. Reduce the ratio: 2-6 = 1-3

2. Write each of them as a fraction of a whole:

Small total = 3/(1+3) = 3/4 of the total amount

3. Multiply the ratio to get the answer: 3/4 * 100 = 75

21 is 20% of what number

Ksenya-84 [330]

Answer:

21 is 20% of 105

Step-by-step explanation:

20% * x = 21

20/100 * x = 21

x = 21 * 100/20

x = 105

If you are using a calculator, simply enter 21×100÷20, which will give you the answer.

A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul

Alexandra [31]

45 million * $2^{4}$ = 45million * 16 = 720million

Or you can use
$y=Ae^{kt}$
A is equal to 45 million
To find the rate, k, we can plug in:
$90million=45million*e^{k*1}
$
$2=e^{k}$
$k=ln(2)$
$y=4.5*10^{7}*e^{t *ln2}$
Knowing that t = 4
$y = 4.5*10^{7}*e^{ln(2)*4}
$
$y = 720 million$
