9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle

Answers

Answer 1

Answer:

The correct answer is = p = 15 and q = 6.

Step-by-step explanation:

Given:

Perimeter of rectangle = 42 cm

p - q = 9 cm

length = p

width = q

we know:

Perimeter of rectangle= 2(l+w)

solution:

42 = 2(P+q)

21= p+q

Difference of p and q = 9 cm.

Then, P+q=21 .... 1

P-q=9 ....2

Adding both 1 and 2

2P = 30

P= 15cm and

q = 15-9

= 6cm

3 is a prime number so to split it up you would put 3y in one parentheses and y in the other. at this point it will look like this
(3y )(y )
now, you need to figure out what your signs would be (+ or -) because the second sign in the equation is a negative, your signs would be one + and one - you can decide where to put them until you figure out your two factors. in this case you need to figure out 2 numbers that multiply to 5 and add up to 2. you might think this is impossible, but since the 3 is there, one of those numbers can be multiplied by three. this is your answer:
(3y-1)(y+2)

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1 4of the total distance. What fraction of the total distance do they have left after

Answers

Answer:

5/12

Step-by-step explanation:

Total distance travelled = 30% + 1/4

To add these numbers, convert 30% to fraction

30% = 1/3

1/3 + 1/4 = 7/12

Remaining distance = 1 - 7/12 = 5/12

The midpoint of overline AB is M(0, - 7) . If coordinates of A are (- 2, - 6) , what are the coordinates of B?

Answers

Given:

The midpoint of overline AB is M(0, - 7) .

The coordinates of A are (- 2, - 6).

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

The midpoint of overline AB is M(0, - 7). Using the midpoint formula, we get

[tex]M=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]

[tex](0,-7)=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{-2+a}{2}=0[/tex]

[tex]-2+a=0[/tex]

[tex]a=2[/tex]

And,

[tex]\dfrac{-6+b}{2}=-7[/tex]

[tex]-6+b=-14[/tex]

[tex]b=-14+6[/tex]

[tex]b=-8[/tex]

Therefore, the coordinates of point B are (2,-8).

How do I find the missing side length for 30 - 60 - 90 method as a radical in simplest form? ​

Answers

Answer:

Step-by-step explanation:

see the image below

Step-by-step explanation:

The side that is adjacent to 60 degree and 90 degree is the shortest side.

If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5

If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.

The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.

If u know the shortest side, just multiply the radical

[tex] \sqrt{3} [/tex]

to the whole number.

If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side

Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.

If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.

If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.

E.x if the second longest side length is

[tex]5 \sqrt{3} [/tex]

Remove the radical so it becomes

[tex]5[/tex]

then multiply it by two to find the hypotunese.

[tex]5 \times 2 = 10[/tex]

Two vertical posts stand side by side. One post is 8 feet tall while the other is 17 feet tall. If a 24 foot wire is stretched between the tops of the posts, how far apart are the posts?​

Answers

Answer:

22 1/4 feet

Step-by-step explanation:

you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).

use Pythagorean Theorem to find the base side, which represents the distance between the posts

a² + 9² = 24²

a² + 81 = 576

a² = 576 - 81

a² = 495

a = [tex]\sqrt{495}[/tex]

a = [tex]\sqrt{9}[/tex] · [tex]\sqrt{55}[/tex]  =  3[tex]\sqrt{55}[/tex], which is approx 22.25

Answer:

about 22.25 feet

Step-by-step explanation:

You can think of it like a triangle, which you can see at the bottom

Then, use the pythagorean theorem, [tex]a^2 + b^2 = c^2[/tex].

you have a = 9 and c = 24, so

[tex]9^2 + b^2 = 24^2\\81 + b^2 = 576\\b^2 = 495\\b = \sqrt{495} = 3\sqrt{55} = about 22.25[/tex]
