Answer:
320 cm difference
Step-by-step explanation:
<h3>Volume for Triangular prism: (1/2)(b)(h)(H)</h3><h3>Volume for Triangluar pyramid: (1/3)(1/2)(b)(h)(H)</h3>
480-160=320
Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.
For a few moments, call the square root of 5 by the name "cow".
cow - x = 4 . Solve this equation for 'x' :
Add 'x' to each side of the equation: cow = 4 + x
Subtract 4 from each side: cow - 4 = x
Now, we can put the real value back in place of 'cow' : <u>√5 - 4 = x</u>
That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:
√5 = 2.2361 (rounded)
x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
Answer:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Step-by-step explanation:
Solution: The needed answer for first blank is 1 and the needed a for second blank is 1.
Explanation:
The given equation is 
.
The form of perfect square is 
.
The given equation can be written as 
.
To make the perfect square we can add or subtract 
in the given equation. Where, a is coefficient of 
and b is coefficient of x. In the parenthesis the coefficient of is 1 and coefficient of x is 2.
So, the given equation is written as 
Therefore, the needed answer for first blank is 1 and the needed a for second blank is 1.
Answer:
- A. The temperature –5º C is colder than the temperature –2º C .
- D. The temperature –5º C is warmer than the temperature –7º C
Step-by-step explanation:
The more negative a temperature is, the colder it is. In order, from colder to warmer, the temperatures are ...
colder ... ... ... ... warmer
-7 ºC ... -5 ºC ... -2 ºC
