I need the thing for the square pizza ill give brainlest to who gets its right
baherus [9]

Answer:

A) The square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.

B) There's more crust on the square pizza then on the circle one, according to 60>50!

Step-by-step explanation:

A)First, let's calculate the area of the round pizza.

We need to find out the radius, and radius=\frac{diameter}{2}

So radius=16/2, which is 8.

And a circle's area is \pi r^{2}, so the equation for this round pizza is:

\pi                (8)^{2}

=64\pi

≅201 inch^{2}

Second, we calculate the square pizza's area, which is pretty easy since the equation for a square is: (Side Length)^{2}.

So for this square pizza, the area would be:

(15)^{2}

=225 inch^{2}

Lastly, we compare the two, 225>201, so the square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.

B)So this problem is actually asking you to find the circumference of the circle and perimeter of the square.

Let's start off with the circle, the formula for circumference is:

\pi (d)

We already have the d, (diameter), which is 16, so the circumference of this circle pizza is:

16\pi

≅50 inch

Then we find the a square's, the equation for perimeter is:

4 (side length)

=4(15)

=60 inch

So happily, we found out there's more crust on the square pizza then on the circle one, according to 60>50!

How would you solve this problem?
vfiekz [6]

Answer:

x = 47

Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles for a triangle

2x-2   = x + 45

Subtract x from each side

2x-2 -x = x+45-x

x-2 = 45

Add 2 to each side

x-2 +2 = 45+2

x = 47

Which is equation in point slope form for the given point and slope. Point5,9 slope2
Sedbober [7]

Answer: y - 9 = 2(x - 5)

Step-by-step explanation:

Point slope form: y - y1 = m(x - x1)

substitute 5 for x1 and 9 for y1 and 2 for m

x1 = 5

y1 = 9

m = 2

you get y - 9 = 2(x - 5)

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
andriy [413]

Answer:

<h2>Yes, this is a right triangle.</h2>

Step-by-step explanation:

Hypotenuse always have the highest number than base and perpendicular.

Hypotenuse ( h ) = 15

Base ( b ) = 9

Perpendicular ( p ) = 12

Let's see whether the given triangle is a right triangle or not

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

Plugging the values,

{15}^{2}  =  {12}^{2}  +  {9}^{2}

Evaluate the power

225  = 144 + 81

Calculate the sum

225 = 225

Hypotenuse is equal to the sum of perpendicular and base.

So , we can say that the given lengths of the triangle makes a right triangle.

Hope this helps..

Best regards!!
