Answer:
Surface area is the sum of all of the areas of the faces in a solid figure. To find the surface area, we must be able to calculate the area of each face and then add these areas together. A net is a two-dimensional diagram of a three-dimensional figure. With a net, we can see each face of the pyramid more clearly. To find the surface area, we need to calculate the area for each face in the net, the sides and the base. The side faces of a pyramid are always triangles, so we use the area formula for triangles to calculate their area: A=1/2 bh (BASE TIMES HEIGHT)..
Step-by-step explanation:
Answer:
A, AA similarity
Step-by-step explanation:
the first similar angle is from the vertical angles and there are 2 more because the end sides are parallel and when they intersect with the same line it will make it have the same degree. It may look SAS but the figure may not be drawn to scale and there is no proof for it.
Answer:
Karl prepared 30 liters in 5 hours
Step-by-step explanation:
The total amount of juice Karl prepares per unit time can be expressed;
T=U×h
where;
T=total number of liters of juice prepared
U=number of liters prepared per unit time
h=number of working hours
In our case;
T=12 liters
U=U
h=2 hours
replacing;
12=U×2
2 U=12
U=12/2
U=6 liters per hour
The unit rate=6 liters per hour
Solving for 5 hours
Total quantity of juice prepared=Unit rate×number of hours worked
where;
Unit rate=6 liters per hour
Number of hours worked=5 hours
replacing;
Total quantity of juice prepared=(6×5)=30 liters
Karl prepared 30 liters in 5 hours
