If the diagonal of a square is 12√2 cm . Find its area

Answers

Answer:

A = 144 cm²

Step-by-step explanation:

Let the side of the square be x. Using Pythagoras theorem for square,

[tex]x^2+x^2=(12\sqrt2)^2\\\\2x^2=288\\\\x=12\ cm[/tex]

The area of the square is given by :

A = side²

Put values in the formula.

A = 12²

A = 144 cm²

So, the area of the square is equal 144 cm².

y=-7/4x-3/4

Step-by-step explanation:

you need to but the equation in y=mx+b form first

if you take the y and divide all other numbers.

y=-7/4x-3/2

then you already have your slope of -7/4, you don't need to divide by 1/2

you then divide the -3/2 by the 1/2 for your final answer.

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 28.26 cubic inches of popcorn. If the height is 19 inches, what is the radius?

Answers

Answer:

1.2 in approx

Step-by-step explanation:

Given data

Volume of the cone= 28.26 in^3

Height= 19 in

Radius= ????

We know that the volume of the cone is expressed as

V= 1/3πr^2h

substitute

28.26= 1/3*3.142*r^2*19

28.26= 19.89*r^2

divide both sides by 19.89

r^2= 28.26/19.89

r^2= 1.42

r=√ 1.42

r= 1.19

Hence the radius is 1.2 in approx

Step-by-step explanation:

You can use process of elimination for this one. So first, obviously it wont be lower than the last test score which is at 65%, so you can mark off A and B. Then, if you notice the test scores fall right next to the big blue line, so find 9 hours, and then look all the way up to where it touches the line and you can see it is about a little less than 80%, which can mean that it obviously ain't D, so it is therefore C.
