B. Sample

it is asking for the students' opinions probably for a study of some sort, you wouldn't ask students any question when measuring population

PQ is parallel to RS. PR and QS are perpendicular to PQ and RS the ratio of the lengths of PR and QS is......

Lady bird [3.3K]

$\frac{PQ}{PR} = \frac{RS}{QS}$ → $\frac{PR}{PQ} = \frac{QS}{RS}$

the ratio of PR to QS is 1:1 because they are congruent (equal)

If you draw a picture, you will see that PQRS is a parallelogram.

The width of a rectangle is 4 inches greater than half the length. The perimeter is 56 inches. What is the length and the width

yulyashka [42]

Answer:

Length of the rectangle = 16 inches

Width of the rectangle = 12 inches

Step-by-step explanation:

Let the length of the rectangle be represented by x.

Then width can be expressed as $\[\frac{x}{2}+4\]
$

Perimeter of a rectangle is the sum of four sides of the rectangle.

This can be expressed as 2*(length + breadth)

= $2* (x + \frac{x}{2}+4)$

= $2* (\frac{3x}{2}+4)$

= $3x + 8$

But perimeter is given as 56.

So, $\[3x + 8 = 56\]
$

=> $3x = 48$

=> $x = 16$

Hence length of the rectangle = 16 inches

Width of the rectangle = $\frac{16}{2}+4$ = 12 inches

HLEPPPPPP!!!!!

Ksenya-84 [330]

Answer:

Solutions:-5,0,9,6

Not solutions: 12.5,10

Explanation:

The inequality that was given is:

20 > 5 + 3x

First, group similar terms;

20 - 5 < 3x

15 < 3x

x = 5

Thus, the solutions are:-3.5, 5, 4 3/4, -15

The not solutions are:-10 2/3, 129,

Hope this helps! :)

Can anyone help me, i will give brainiest.

Answer: ∠DOB: 48°

Step-by-step explanation:

1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°

2. now we can solve for the missing variable, n.

108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°

3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°

hope this heped! ♡
