<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>
<em><u>Solution:</u></em>
The given pyramid has 3 lateral triangular side
The figure is attached below
Base of triangle = 12 unit
<em><u>Find the perpendicular</u></em>
By Pythagoras theorem
Therefore,
<em><u>Find the lateral surface area of 1 triangle</u></em>
<em><u>Thus, lateral surface area of 3 triangle is:</u></em>
3 x 48 = 144
Thus lateral area for the pyramid with the equilateral base is 144 square units

Answer:
1) W = 10
2) x = 33/2
Step-by-step explanation:
These are 2-step linear equations. Step 1: Add the opposite of the constant on the right. Step 2: Divide by the coefficient of the variable.
__
1) 15 = 2W -5
20 = 2W . . . . . add +5
10 = W . . . . . . . divide by 2
__
2) 24 = 2x -9
33 = 2x . . . . . add +9
33/2 = x . . . . divide by 2
_____
As always, whatever you do to one side of the equation must also be done to the other side. That is, the same number is added to both sides; both sides are divided by the same number.
Answer:
$13.60 in change
Step-by-step explanation:
2.5 lbs x $1.00 = $2.50 for pears
1.3 lbs x $3.00 = $3.90 for apples
$2.50 + $3.90 = $6.40 paid total
$20.00 - $6.40 = $13.60 change
Answer:
6
Step-by-step explanation:
Hope thats the correct answer.
Well, first of all, you have to open up the bracket by multiplying what's outside by what's inside. Anyway;
3k-15=-16
Next, you have to collect the like terms and put them together. And the -15 becomes +15. So;
3k=-16+15
3k=-1
Next, you have to divide the both sides by 3. So;
3k/3=-1/3
k=-1/3
So your answer is -1/3. Hope i helped. Have a nice day.
