I need help please... I'll mark you brainiest!!! Thanks!
1 answer:
Multiply the weight in tonnes by the conversion factor ( 1 tonne = 1000 kg) to get the weight in kg's:
170 tonnes x 1000 = 170,000
Now convert to scientific notation, by moving the decimal point to have only 1 digit to the left of the decimal.
To do this, you would need to move the decimal 5 places to the left to get 1.70000
Now remove the 0's and multiply the number by 10 raised to the number of paces the decimal was moved to get:
1.7 x 10^5 kg's.

12,571.4286 you subtract 1000 from the total, and divide by 7.
Answer:
$699
Step-by-step explanation:
90.87 * 5 = 454.35
454.35 = 65%
/65 /65
6.99 = 1%
*100 *100
$699 = 100%
Total Cost = $699
12a³ + 12a² = -3a | + 3a
12a³ + 12a² + 3a = 0
3a(4a² + 4a + 1) = 0
3a(2a + 1)² = 0
3a = 0 or (2a + 1)² = 0
1) 3a = 0 | : 3
a = 0
2) (2a + 1)² = 0
2a + 1 = 0 | - 1
2a = -1 | : 2
a = -1/2
a ∈ {-1/2, 0}
Used formula:
(a + b)² = a² + 2ab + b²
Answer:
-52
Step-by-step explanation:
You can clear fractions by multiplying by 3:
3(1/3x) -3(2/3) = 3(-18)
x -2 = -54
add 2:
x = -52
