Answer:
To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then:
add basic figure volumes belonging to the composite shape.
subtract basic figure volumes NOT belonging to the composite figure.
Step-by-step explanation:
10 people who build at the same rate can frame a house in 6 days. That means it will take one person
days to finish the house.
Which means that it will take 4 people
days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be 
Thus, Option D is the correct answer.
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of aline:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

From the graph we have the points:
(-2, -5)
y-intercept (0, 3) → <em>b = 3</em>
Calculate the slope:

Put the value of the slope and the y-intercept to the equation of a line:

Answer:
C: 50%
Step-by-step explanation:
There are 2 even numbers and 2 odd numbers on the spinner.
Therefore, the probabilty of getting an odd number is 2/4 = 1/2 = 0.5 = 0.5 x 100 = 50%
Area is Base times Height.
the height is 5, and the base is 7 so our equation is
5×7
the answer is 35
