Alicia did not use the correct amount of flour, but she did use the correct amount of oats. The reason she is incorrect is that if she made double the batch, then she would have doubled the amount of flour that she was suppose to used.
All you do is multiply like 6 times 2 of the power of ten is like 6 times 100
Answer:
Step-by-step explanation:
Scientific notation is a quick way to represent a number using powers of base ten. This notation is used to be able to express very large or very small numbers very easily.
The numbers are written as a product:
a * 10ⁿ
where:
- a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
- n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it shifts to the left, negative if it shifts to the right.
Comparing what is equal to these two numbers when they are written in scientific notation you can see that the value of a is such that 1 ≤ a <10
Comparing what is different from these two numbers when they are written in scientific notation, you can see that the value of the exponent n in both numbers is different, one being positive, indicating that it is a very large number, and the other negative, indicating that it is It is a very small number that is between 0 and 1.
T = Tarts
C = Cookies
David:
3T + 5C = 10.50
Lisa:
4T + 8C = 14.80
Setup as system of equations and use substitution or elimination
Elimination is easier for this case but either will give you the right answer I worked it both ways
T= cost of tarts = $2.50
C= cost of cookies = $0.60
The y-intercept is -8 because when you put it in standard form you subtract 8x from both sides which give you-3y=-8x+24. Then you divide both sides by -3 which gives you y=8/3x-8. Since the form is y=mx+b, b is the y-intercept so it would be -8.
