find the area of a triangle with the following dimensions: a = 12 yards b=16 yards and c=24 yards round to the nearest square yard

Answers

Answer 1

Answer:

Answer:c=35

Step-by-step explanation:

Answer 2

Answer: P=52 yards
p=26 yards
A=square p(p-a)(p-b)(p-c)
A=square26(26-12)(26-16)(26-24)
A=square 26x14x10x2
A=85 yards^2

Distance between (-1,2) (7,8)

Answers

The distance between any two points is

   square root of ( [difference in the 'y's]² + [difference in the 'x's]² )

Difference in the 'y's = 8 - 2 = 6
Difference in the 'x's = 7 - (-1) = 8

Distance between them =

   square root of ( 6² + 8² ) =

   square root of ( 36 + 64 ) =

   square root of ( 100 ) = 10 .

Answer: 10

Step-by-step explanation: In this problem, we're asked to find the distance between the points (-1,2) and (7,8) so we use the distance formula which states that the distance between two points is equal to

$d =\sqrt{(x^(2) - x^(1))^(2) + (y^(2) - y^(1))^(2) }$ .

Our first point, (-1,2) represents ( $^(x) 1$ , $^(y)1$ ) and our second point,

(7,8) represents ( $^(x)2$ , $^(y)2$ ).

So, plugging the given information into the formula, we have $\sqrt{7 - (-1))^(2) + (8 - 2)^(2)}$ .

Next, we simplify inside the parentheses to get $\sqrt{(8)^(2) + (6)^(2)}$ .

Next, 8² is 64 and 6² is 36 so we have $√(64 + 36)$ or $√(100)$ which is 10.

So the distance between the points (-1,2) and (7,8) is 10.

Whats the square root of -63 using radicand?

Answers

32=3⋅3=932=3⋅3=9

9 was the square of 3. The square of -3 is 9 as well

(−3)2=(−3)⋅(−3)=9(−3)2=(−3)⋅(−3)=9

3 and -3 are said to be the square roots of 9.

All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots

a2=a⋅a=(−a)⋅(−a)a2=a⋅a=(−a)⋅(−a)

A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.

a√a

To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.

±9√=±3±9=±3

Zero has one square root which is 0.

0√=0

remember
√(mn)=(√m)(√n)

so
√-63=(√-1)(√63)

63=3*3*7
√63=3√7

√-63=(3)(√7)(√-1)
√-63=(3)(√-7)
√-63=3√-7

What percent of 62 is 31

Answers

Umm. I assume you mean "If I have 31 out of 62 what percent of 62 do I have." The answer is 50%.

31*2=62 so that means that 62 is 200% of 31

Does a polygon have more sides or angles?

Answers

I think you're asking: "Which does a polygon have more of ... sides or angles ?"

This is a perfect example of where you spent more time and effort
posting your question on the internet than what it would take you
to answer it for yourself.

Can you draw a picture of a triangle ?
You'll see it has 3 sides and 3 angles.

Can you draw a picture of a square ?
You'll see it has 4 sides and 4 angles.

Can you draw a picture of a shape with 5 sides ?
You'll see that it has 5 angles.

Can you draw a shape with 6 sides (like s STOP sign) ?
You'll see that it has 6 angles.

By now, you would be getting the crazy hunch that maybe the
sides and angles of a polygon always happen in the same number.
THEN you would get on Brainly and ask: "I have been working
with some polygons, and I noticed that every polygon I tried had
the same number of angles as it had sides. Is this always true
for any polygon ?"

If I saw that question, I would jump on it with joy, because it feels
so good to help someone who doesn't mind putting some of his
own time and effort into a question.

I would answer "YES !", and then find 15 other characters to fill the minimum.

quadrilateral, triangle, hexagon, pentagon, etc are polygons
it depends on what kind of shapes like how many sides
but ex : rectangle has more sides than triangles so some of them yes, and some of them, no
