Step-by-step explanation:
given
a = - 3
3a² = 3 * ( -3) ²
= 3 * 9
= 27
The value of 3a² is 27.
2000 * .1 = 200 + 2000 = 2200 (First year)
2200 *.1 = 220 + 2200 = 2420 (second year )
2420* .1 = 242 + 2420 = 2662 (third year )
2662 * .1 = 266.2 + 2662 = 2928.2 (fourth year)
They spent $2928.2 on clothing for 4 years.
1 Is C, 2 Is A, 3 Is B, The Reason Why Is Because The Formula For Voulume Is V = (R*R)*3.14 * H. I Hope This Helps!
Answer:
71 degrees.
Step-by-step explanation:
m < CED = 180 - 152 = 28 degrees ( adjacent angles).
m <BAC = 28 degrees( alternate angles).
m < ACD = 28 + 43 = 71 degrees (external angle theorem).
