Please help total surface area

161ft

Step-by-step explanation:

Area of a triangle is 1/2 (base x height)

2 triangles at:

1/2(5ft x5ft) = 12.5ft

1/2(5ft x 5ft) = 12.5ft

Then the area of the 3 rectangles

8 x 7 = 56ft

8 x 5 = 40ft

8 x 5 = 40ft

12.5ft + 12.5 + 56ft + 40ft + 40ft = 161 ft

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
