Answer:

width= 0.5 per side, 1 in total; length= 8.5 per side, 17 in total

Step-by-step explanation:

because 8.5*2=17, then 8.5-8=0.5. so then 0.5*2=1 and 17+1=18. I CAN EXPLAIN FURTHER

we know that

An <u>angle bisector</u> is a line or ray that divides an angle into two congruent angles

so

in this problem

m∠RST=m∠RSV+m∠VST

m∠RSV=m∠VST

hence

m∠RST=2*m∠RSV --------> equation 1

we have

m∠RST=(6x-24)

m∠RSV=(2x+8)

Substitute in the equation 1

6x-24=2*(2x+8)

6x-24=4x+16

6x-4x=16+24

2x=40

x=40/2

x=20 degrees

therefore

<u>the answer is the option </u>

D definition of angle bisector

and the value of x is 20 degrees

The table of values shown below represents a linear function. Which of these points could also be an ordered pair in the table,

maks197457 [2]

Answer:

(18,27) , because the rate of change of the function is $\frac{4}{3}$

Step-by-step explanation:

step 1

Find the slope of the linear equation

Looking at the table

we have the points (0,3) and (3,7)

The slope is equal to

$m=(7-3)/(3-0)=\frac{4}{3}$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=\frac{4}{3}$

$b=3$ -----> point (0,3) is the y-intercept

substitute

$y=\frac{4}{3}x+3$

The rate of change of the linear equation is equal to $\frac{4}{3}$

Remember that

If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation

<u><em>Verify </em></u>

1) point (18,27)

substitute the value of x and the value of y in the linear equation

$27=\frac{4}{3}(18)+3$

$27=24+3$

$27=27$ -----> is true

so

The ordered pair is a solution of the linear equation

therefore

The point (18,27) could also be an ordered pair in the table

2) point (27,18)

substitute the value of x and the value of y in the linear equation

$18=\frac{4}{3}(27)+3$

$18=36+3$

$18 \neq 39$ -----> is not true

so

The ordered pair is not a solution of the linear equation

therefore

The point (27,18) could not be an ordered pair in the table

Two tomato seeds were planted and watered after six weeks ,plant was 26cetmeters tall.the plant only 74% as tall what was hight

nlexa [21]

The shorter plant was 19.24 cm in height.
74% is equal to 0.74, so the height of the shorter plant can be found by multiplying 0.74 by the height of the taller plant, 26 cm.

26 * 0.74 =19.24
so the height of the shorter plant is 19.24 centimeters

Mary has two bags of sweets, each of which contains the same number of sweets. She eats four sweets. She then finds that she has

Vlad1618 [11]

Given that Mary has 2 bags of sweets. each of which contains same number of sweets.

Let us assume each bag contains x number of sweets.

After eating 4 sweets, total number of sweets left in two bags = x+x-4=2x-4

But given 2x-4 = 30

2x-4+4 = 30+4

2x=34

$x=\frac{34}{2} = 17$

Hence there are 17 sweets in each bag at starting.
