Answer:
Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.
Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ
Hence, if we find the ratio of this, we can use it to find the side <em>h</em>
<em>QZ/ST=PZ/RT</em>
<em>48/12=PZ/4</em>
<em>PZ/4=48/12</em>
<em>(PZ/4)3=48/12</em>
<em>PZ(3)/12=48/12</em>
<em>48/3=16</em>
16=PZ.
3Step-by-step explanation:
The answer here is 275 miles, because it is going at 55 miles per hour. you can find this out by dividing the miles by the hours. Hope this helps.
Answer:
It Depends
Step-by-step explanation:
If the image is the scale, the answer is 1/3, since its width of 3 is 1/3 the width of the actual book.
If the book is the scale, the answer is 3, since its width of 9 is 3 times the width of the image.
Answer:
The volume is changing at a rate given by:
Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone = 
where B is the area of the base (a circle of radius R) which equals = 
and where H stands for the cone's height.
We apply the derivative over time operator (
) on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:
