What is the base of a triangle that has an area of 60 square centimeters and a height of 8 centimeters? A 7.5 cm
B 30 cm
C 52 cm
D 15 cm

I think its (A)

Step-by-step explanation:

To find the area you have to multiply (b*w)*h

and if the area is 60 you just have to divide by the height to get the base area.

60/8=7.5

Hope this helps :3

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
