15 is the answer i divided
I honestly don’t know I am just doing this because I need to ask a question hope I helped
Answer:
2.
30-7x4 = 2
3.
80
Step-by-step explanation:
2.
First, do 7x4, which equals 28. Then subtract that from 30, and you get 2.
3.
Do the parentheses first, 21-6=15. Then 15 divided by 0.2 = 75. 75+5=80.
Sorry I couldn't help on any of the other ones, I don't have much time.
The length of the square base is thus
= A
<h3>What is hemisphere?</h3>
Consequently, a hemisphere is a 3D geometric object that is made up of half of a sphere, with one side being flat and the other being a bowl-like shape. It is created by precisely cutting a spherical along its diameter, leaving behind two identical hemispheres.
EXPLANATION; Let ABCDE be the pyramid with ABCD as the square base. Let O and M be the center of square ABCD and the midpoint of side AB respectively. Lastly, let the hemisphere be tangent to the triangular face ABE at P.
Notice that triangle EOM has a right angle at O. Since the hemisphere is tangent to the triangular face ABE at P, angle EPO is also 90 degree. Hence, triangle EOM is similar to triangle EPO.
OM/2 = 6/EP
OM = 6/EP x 2
OM = 
The length of the square base is thus
= A
