Answer:

200 minutes ; 3 hours and 20 minutes.

Step-by-step explanation:

If you write a proportion in the form

miles/minutes = miles/minutes

you would get 3/50 = 12/x

from there you cross multiply to get

3x=600, and solve that to get 200 minutes.

another way was to see that 12 is 3*4, and multiply 50 by 4 to get the same answer.

Answer:

Option A. $(a/2,0)$

Step-by-step explanation:

we know that

If triangle ABC is a right isosceles triangle

then

AB=AC

m<ABC=m<ACB=45°

therefore

The coordinate of point C is $(a,0)$

the x-coordinate of the midpoint M is equal to

$(0+a)/2=a/2$

The coordinates of point M are $(a/2,0)$

What is the surface area? 5 mm 4 mm 5 mm 6 mm 6 mm square millimeters

mylen [45]

Answer:

6 x 4 = 24, 24 divided by 2 = 12(area of 1 triangle)

12 x 2(two triangles) = 24

5 x 6 = 30(area of 1 slanted rectangle)

30 x 2(two rectangles) = 60

6 x 6 = 36(area of bottom square)

Add all given AREAS:

24 + 60 + 60 = 144 mm2 is your answer.
