The anwser is 49 step by step
Area of lower triangular prism:
1/2 x L x H X W
1/2 x 8 x 4.5 x 30 = 540
area of top triangular pyramid
1/3 x B x H
B = 1/2 bxh = 1/2 x 8 x 4.5 = 18
1/3 x 18 x 10 = 60
total volume = 540 + 60 = 600 cubic cm
Answer:
The correct option is;
B) Discrete linear
Step-by-step explanation:
The graph shows scatter plots of the data points and therefore the plot is a discrete plot of points. Also, we have, from the graph of the function, changes in input values are proportional with changes in output, such that the progression of the points are unidirectional.
Therefore, the graph is a discrete linear function.

Answer:
200
Step-by-step explanation:
Of the apartments in the building, 20% are singles and 70% of those do not have balconies.
That is, (0.20 × 0.70) = 0.14 of the building's apartments are singles without balconies. That is 28 apartments. If A is the number of apartments in the building, this means
0.14A = 28
A = 200 . . . . . divide by 0.14
There are 200 apartments in the building.
