Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h
23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified
24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values
.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

Answer:
C. 7790.83 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We know the radius is 12.3
Using 3.14 for pi (This will give us an approximation, not an exact value)
V = 4/3(3.14) (12.3)^3
=7790.82984 cm^3
Answer:
10
Step-by-step explanation:
2/3 can be multiplied by 5 to equal 15ths since we can know 15 (seconds number fraction) is 5 times the originals (first numbers fractions)
This equals to 10/15 and means that with 1/15th on each 10 sandwiches can be made.
The answer gives it straight forward but explanation gets in depth
Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.
2/3
x5
10/15
Hope that helps some more
Answer:

Step-by-step explanation:
3 different china dinner sets, each consisting of 5 plates consist of 15 plates.
A customer can select 2 plates in

different ways.
2 plates can be selected from the same dinner set in
