Answer:
All the none-zero digits given should be included when written in scientific notation. But also any trailing zeros written after non-zero digits should also be included.
For example in 0.00900 the 900 is significant because the person who included the trailing zeros is saying look I measured this far and these zeros are significant.
Answer:
9
Step-by-step explanation:
18+45 is 63
2+5 is 7
63/7 is 9
x=9
cost of apples is based on weight (lbs) so this is the rate, the bag is a flat fee.
y = mx + b ⇒ Cost = rate(lbs) + bag ⇒ C = 1.29(a) + 0.25
Answer: #3: c(a) = 1.29a + 0.25
Because both lines AT and AN are tangents, they are equal to each other.
Because angle ATN is 70 degrees, then angle ANT is also 70 degrees
The 3 inside angles of a triangle = 180 degrees,
so angle A would = 180 - 70 - 70
Angle A = 180 -70-70 = 40 degrees
