Isabella cares for an aquarium that is 6 feet long and has a height of 4 feet.The aquarium needs 72 cubic feet of water to be completely filled.What is the width of the aquarium?

Answers

Answer 1
Answer: Using the formula V=whl Solving for w w=V/(h)(l) w=72/(4)(6) w=3 The width is equal to 3 feet when the length = 6, height = 4 and Volume = 72

A homeowner leans a ladder against his house so that the top of the ladder makes a 31 degree angle with the house. What angle does the bottom of the ladder make with the ground? help! asap

Answers

If you put an imaginary line from the base of the ladder to the wall it would from a right angled triangle. The internal angles of a triangle all add up to 180degrees. With a right angled triangle, we know for sure one angle is going to be 90 degrees. One angle as you said is 31 degrees so you just add 31 and 90 which is equal to 121 then subtract it by that. SO:
180-(31+90)
180-121=59 degrees
or even easier
90-31= 59

Which is the best definition of a quadrilateral? A( A four sided polygon with no equal sides
B(a parallelogram with no equal sides
C( A four sided polygon
D( A parallelogram with two pairs of equal angles
P.s I already asked this question once but it wouldn't let me edited it to put the answer choices)

Answers

quad=4
lateral=sides

basically is is a 4 sided figure

C is right answer
A polygon is a shape with straight edges with 3 or more sides. A quadrilateral is a shape with four sides and straight edges. So I would say C is your best shot.

in the town zoo, 3/28 of the animals are birds. of the birds, 4/15 are birds of prey. what fraction of the animals are birds of prey?

Answers

let's call the animals "a" and birds "b"

b=(3)/(28)a

we knot this from3/28 of the animals are birds.

and we also know that 4/15 are birds of prey.  so

p=(4)/(15)b

we could substitute:

p=(4*3)/(15*28)

and solve:

p=(1)/(35)
and this is the answer!

How do I find the the perimeter of a rectangle
in a coordinate plane

Answers


From the way you worded the question, it sounds like you have
the (x, y) coordinates of each corner of the rectangle.

The perimeter of any shape is the distance all the way around it,
or the sum of the lengths of all the sides.

So you have to take the coordinates of the four corners of the
rectangle, and find the length of each side ... that's the distance
between each pair of corner-points.  Then addum up to get the
perimeter.

I know finding the distance between two points is a pain, so I'll
tell you a way to make it a bit simpler:  You don't actually need to
do it 4 times.  You can get away with doing it only 2 times, and
you'll have enough information to find the perimeter.

Take the coordinates at the ends of any side of the rectangle.
Find the distance between them.  The side opposite that one
has the same length.

Then take the coordinates of either side that hooks onto the
side you just did.  One end of it will have the same coordinates
that you just worked with.  Find the distance between the two ends.
You know that this distance is the other dimension of the rectangle,
and you also know that the side opposite it has the same length.

So now, you found the distance between two pairs of points,
and you know both dimensions of the rectangle, and you know
the length of all four sides.

Now you can wrap it up !
