Answer:

150 m

Step-by-step explanation:

So the scale of the model is 1 cm = 5 m, and the model is 30 cm long. We can set this up as two fractions, then cross-multiply, like so:

1 cm/30 cm = 5 m/x m

1 * x = x

30 * 5 = 150

Now, set the two products equal to each other. Normally we'd have to simplify, but x is already on its own, so we have our answer:

x = 150 m

You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?​
romanna [79]
<h3>Answer:  1/6</h3>

====================================================

Explanation:

Let's say for example this pizza had 6 slices to start with. Two-thirds of this is (2/3)*12 = 4 slices. So you have 4 slices left over from yesterday. Then let's say you hand one slice to each of your four friends. Each friend would have 1/6 of the original pizza.

A pine cone drops from a tree branch that is 36 feet above the ground. The function h = –16t2 + 36 is used. If the height h of t
scoray [572]
Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, h, with 0 in the function, and solve for time t:
h=-16t^2+36
0=-16t^2+36
-36=-16t^2
t^2= \frac{-36}{-16}
t^2= \frac{9}{4}
t=(+/-) \sqrt{ \frac{9}{4} }
t=(+/-) \frac{3}{2}
t=(+/-)1.5
Since time cannot be negative, the solution is t=1.5 seconds.

Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>
