Scientific notation review
A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 multiplied by a power of 10.
If we have a number greater than 10, we move the decimal point to the left until we have a number between 1 and 10. ...
Let's write 604 , 000 604{,}000 604,000 in scientific notation.
It’s the new update
If we set the amount of hours she needs to babysit as x, his word problem can be shown as:
3+ 7.50x = 25.50
Now we can just solve for x
25.50-3= 22.50
22.50/7.50 = 3
Therefore she has to babysit 3 hours
14h = c
If c = the total cost, then the equation should end with "= c" because we're trying to find the total cost of renting a row boat.
If the row boat is $14 per hour, that's 14 x hours, or 14h.
Therefore, 14h = c.
Hope this helps
Answer:
Scale factor = 3 : 1
Step-by-step explanation:
Scale factor of figure = 
From the graph attached,
Scale factor = 
= 
[Since size of every square of the graph is same]
= 3
Therefore, scale factor of figure A to figure B is 3.
In other words ratio of the size of figure A to figure B will be 3 : 1.
