Answer: hope this help's

Step-by-step explanation:

Geometry Terms Chapter 3

A B

Coplanar in the same plane

Parallel lines coplanar lines that do not intersect

Intersecting lines coplanar lines that have exactly one point in common

Perpendicular lines lines that intersect at righ- are non-coplanar

- they are not parallel and do not intersect

t angles are non-coplanar

- they are not parallel and do not intersect

- planes that do not intersect - two segments are parallel if the lines containing them are parallel - a line that intersects two or more coplanar lines at different points

- transversal has nothing to do with whether lines are parallel or not - an angle formed between parallel lines by a third line that intersects them

lie on the same side of the transversal and in corresponding positions

alternate exterior angles

- non-adjacent exterior angles that lie on opposite sides of the transversal

12 is 30% of ____ <br> (Please explain)

natka813 [3]

Answer:

Step-by-step explanation:

In word problems, the word "of" usually means multiply. Thus, for example, 10% of $50 is $5. This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply: (1/10)(50) = 5

So, we often see equations like:

R = (1/2)D meaning R is 50% of D, or R is half of D

Let x = the number we want to find

This problem says:

"12 is 30% of what number?"

12 = (30/100) * x

12 = (3/10)x

(10/3)12 = x [multiply both sides by (10/3)]

40 = x

Checking (very important):

Is 12 = (3/10)(40) ?

12 = (3)(4) ?

12 = 12 ? yes

A student found the slope of a line that passes through the points (3,15) and (5,9) to be -1/3. what mistake did he make

Vlad [161]

He didn't do it as rise over run, or y2-y1/x2-x1

He did it reverse, which is incorrect.

What is Steven’s slugging average if his stats are- Show steps. 25 singles 10 doubles 3 triples 10 homeruns 140 at-bats

kap26 [50]

<h2>Hello!</h2>

The answer is:

The correct answer is c.

$SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671$

To calculate the slugging average or slugging percentage, we need to divide the number of total bases by the total times at bat.

$SluggingAverage=\frac{TotalBases}{TimesAtBat}$

We know that:

A single means 1 base.

A double means 2 bases.

A triple means 3 bases.

A homerun means 4 bases.

So, we know that:

$Singles=25=25bases\\Doubles=2*10=20bases\\Triples=3*3=9bases\\Homeruns=10*40=40bases\\TimesAtBat=140$

Then, substituting and calculating we have:

$SluggingAverage=\frac{25bases+20bases+9bases+40bases}{140}$

$SluggingAverage=\frac{94bases}{140times}=0.671$

Hence, the correct answer is c.

$SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671$

Have a nice day!

Could somebody help me with this question please?

ELEN [110]

The answer would be 20. Because the whole angle would have to be 90 so you already have 30 so that leaves you with 60 which you divide by 3 and gives you 20
