Mary needs to order pizza for 18 students. Each student should get 1/4 of the pizza. How much pizza will be left over?
Inessa [10]

Answer:

Step-by-step explanation:

Answer:

Order 5 pizza's. There is  

1

2

a pizza left so someone gets an extra portion! Or it is split evenly!

Explanation:

No matter how you present this, the underlying principle is that of ratio.

If each pupil gets  

1

4

of a pizza the 1 pizza feeds 4 students.

So the ratio of  

pizza count

Student count

→

1

4

Need to have sufficient pizza for 18 students. The ratio will be constant so we have:

Let the count of pizzas be  

p

pizza count

Student count

=

1

4

=

p

18

So we now have:

 

p

18

=

1

4

Multiply both sides by  

18

giving:

18

×

p

18

=

1

4

×

18

18

18

×

p

=

18

4

But  

18

18

=

1

p

=

18

4

=

4

1

2

You can not order  

1

2

a pizza so the total pizza count is 5

Suppose a football is kicked with an initial velocity of 82 ft/sec., at an angle of
satela [25.4K]

Answer:

The position P is:

P = 87\^x + 75\^y ft     <u><em> Remember that the position is a vector. Observe the attached image</em></u>

Step-by-step explanation:

The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity s_0 is:

y(t) = y_0 + s_0t -16t ^ 2

Where y_0 is the initial height = 0 for this case

We know that the initial velocity is:

82 ft/sec at an angle of 58 ° with respect to the ground.

So:

s_0 = 82sin(58\°) ft/sec

s_0 = 69.54 ft/sec

Thus

y(t) = 69.54t -16t ^ 2

The height after 2 sec is:

y(2) = 69.54 (2) -16 (2) ^ 2

y(2) = 75\ ft

Then the equation that describes the horizontal position of the ball is

X(t) = X_0 + s_0t

Where

X_ 0 = 0 for this case

s_0 = 82cos(58\°) ft / sec

s_0 = 43.45 ft/sec

So

X(t) = 43.45t

After 2 seconds the horizontal distance reached by the ball is:

X (2) = 43.45(2)\\\\X (2) = 87\ ft

Finally the vector position P is:

P = 87\^x + 75\^y ft
