Answer:

Step-by-step explanation:

Using the definition of factorial

n! = n(n - 1)(n - 2) ....... × 3 × 2 × 1, hence

4! = 4 × 3 × 2 × 1 = 24

A submarine is 600 feet below sea level. It is rising to the surface at a rate of 15 feet per hour. Which expression represents

matrenka [14]

15 × h
h= per hour

and to solve how many hours it would take:

600= 15 × h

600÷ 15 = 40

so it would take 40 hours to rise to the surface

Answer:

area of rectangle : 180 sq ft

area of triangle : 30 sq ft

area of entire composite figure : 210 sq. ft

Step-by-step explanation:

rectangle : 15*12= 180

triangle : 15*4=60 /2 = 30

entire : 180 + 30 = 210

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 can parallel lines be used to compare figures E and F? Explain your reasoning.

Aneli [31]

Answer:

The similarities are

1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long

2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long

3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F

Figure F is essentially the translation of figure E three blocks to right and one block down
