Answer: 5.32 × 10^12
Step-by-step explanation:
This is a question relating to indices. In indices, we add the power given for question relating to multiplication. Hence, this will be:
= (2.8•10^8)(1.9•10^4)
= (2.8 × 1.9) × 10^8+4
= 5.32 × 10^12
Therefore, the answer to the question will be 5.32 × 10^12.

Answer:
66.6%
Step-by-step explanation:
40/60=4/6=2/3
2/3=66.6
12 x 40 = hours she worked = 480
3 x 31 = appointment fee = 93
480 + 93 = 573
Answer:
156
Step-by-step explanation:
Let,
Sandwiches sold by Adam, Matt and Clinton = 2x, 7x and 3x
Total sandwiches = 2x + 7x + 3x
=> 12x
But its given that Matt sold 91 sandwiches
So,
7x = 91
x = 91/7
x = 13
=> Total sandwiches = 12x = 12(13) = 156
