Answer:
6 x 6 x 3 cm
Step-by-step explanation:
The base of the box needs to fit the base of the hemisphere.
The maximum width and length of the hemisphere is the diameter of the base of the hemisphere (which is circular)
Diameter of a circle = 2r
As the radius = 3 cm, the diameter = 2 x 3 = 6 cm
Therefore, the width and length of the box should both be 6cm
The height of the box needs to accommodate the height of the hemisphere. The height of the hemisphere is the radius, so the height of the box should be 3 cm.
Therefore, the dimensions of the box should be 6 x 6 x 3 cm
A- 2b = 2 one of the 2 "A" most be negative so they can cancer each other
-a- b = 6 after the "A" cancel each other add the -2b with -b = -3b, then add 2
-------------- and 6
-3b=8 then you have to divide 8 by -3 = -2.6 -2.6 its b... now you have to solve for b step 1. a -2b = 2 step 2. a -2(-2.6)=2 step 3 a -5.3 = 2 then subtract -5.3 with 2 so that going to be 2 + 5.3 =7.3 then divide by a
final answer (-2.5,-7.3)
sorry its kinda hard to explained here, i hope you get the point :)
Answer:
Step 5
Step-by-step explanation:
The mistake is in step 5.
The previous step was
The order operations, PEDMAS, must be applied:
We have Addition and Division here,
Using PEDMAS, we must divide first to get:
We can now add to get:
Therefore the mistake occurred at step 5
