Answer:
Sebastian didn't interpret the numbers correctly (See explanation)
Step-by-step explanation:
If you go up an elevator, you are gaining floors, so the number is positive.
If you go down an elevator, you are losing floors, so the number is positive.
Looking at the statement, he went 7 floors up to his room, then 9 floors down to the parking garage this can be represented as , since the 7 is positive and the 9 is negative.
Sebastian described the movement as , which is wrong - 9 should be -9 and -7 should be 7.
Hope this helped!
Answer:
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,
<em>A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2. </em>
<em>What is the volume of the pyramid?</em>
My answer:
As we know, The volume of a pyramid = base area × its height
Given:
- Side lenght of the base is;
=> The area of the base is
- In Δ ACB measure of angle ACB is 90° and m∠ CAB is 30°
We use:
<=> BC =
= 4 cm
And BC is the height of the the pyramid
=> The volume of a pyramid =
* 4 cm
=
