Answer:
Step-by-step explanation:
1. 3.8 x 10^5 + 5.5 x 10^5 = 930,000 or 9.3 x 10^5
You just have to solve the equation and shorten the answer. For number one the answer is 930,000, so you have to make it into a number with decimals since a scientific notation number can not be equal to 10 or be greater. So you have to round the number to 9.3 not 93. To "round" it to 9.3 you have to move the decimal at the end of 930,000 to be in between the numbers 9 and 3. How many times you move the decimal to the left or right, that is the exponent of 10. So for 930,000 you moved the decimal 5 times to the left so the exponent for 10 is positive 5.
For the smaller triangle ;
15^2 + b^2 = 17^2
b = 8
To check the work
15^2 + 8^2 = 289
17^2 = 289
(This is if the bottom number on the smaller triangle says 15, its a bit hard to read..)
Answer:
Trinomial
Step-by-step explanation:
Because it is broken up in three terms and trinomial means three terms
Answer:
Step-by-step explanation:I think it's C :)
The answer is 42
first change the numbers from scientific notations into numbers.
1.47*10^7= 14700000
3.5*10^5= 350000
now divide the number of sweets by the number of packets. the quotient is the answer
14700000/350000= 42
good luck
