14. If you have a triangle where the second angle A2 is three times as large as the first angle A, and the third angle A3 is five times the size of the first angle Ai, what are the sizes of each angle?

i would need to see the dot plot : )

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
