Answer: Mary is correct.
9/8 is an improper fraction, so we change it to 1 1/8.
Mary lives less than a mile from school, so we know that Thad lives farther since he lives a mile and 1/8 away, and Mary only lives 6/10 away, which is less than a mile.
Glad I could help, and good luck!
Answer:
(4,-2)
Step-by-step explanation:
If we are reflecting a point across the y-axis, that point must be on the same horizontal line that the pre-mage is was, this means the y coordinate must remain the same. Now we want the points on both sides of the y-axis to have the same distance. x and -x have the same distance from 0. This means you will need to take the opposite of x.
So a point (x,y) being reflected over the y-axis will give (-x,y).
( x , y)->(-x,y) means we have:
(-4,-2 )->(4,-2)
You can graph this to confirm it looks like a reflection through the y-axis.
Answer:
27
Step-by-step explanation:
<u>Step 1: Convert into an expression</u>
Three times nine
3 * 9
3 * 9 → 27
Answer: 27
First, find the area of the piece of fabric, which is 40x38= 1520. (Base times height.)
Then you find the area of the scarf, (triangle.) 1/2x30x27 = 405 (half times base times height is area of triangle formula.)
Finally, subtract the area of the scarf from the fabric to see how much is left over. 1520-405= 1115
I tried to explain it so that it could make as much sense as possible. Sorry if it's a bit hard to understand.
