Lol. I hate Iready. but it think its the bottom left.
because with numbers that have negative exponents, you're suppose to put them over one to get it positive.
ex. 3^-4= 1/3^4
vice versa with the negative sign
We know there are no squares between 100² and 101².
So we just want to know how many numbers between a and b exclusive, which is
n = b - a - 1
For example between 10 and 20 exclusive we get n=20-10-1=9, which is right.
For our problem here we can factor using the difference of two squares and get:
n = 101² - 100² - 1 = (101 - 100)(101 + 100) - 1 = 1(201) - 1 = 200
Answer: d. 200
If you’re trying to find Y then you would add 2.12 to -3.87. your answer would be y-1.75
Multiply 5.2 x 30 and you get 156 miles
Answer:
There are of felt left over.
Step-by-step explanation:
The side of the felt square is 8 cm. A circle of radius 3 cm is cut from the square piece of felt.
The portion of felt leftover is the difference between the area of the square and the area of the circle.
The area of the square is:
The area of the circle is:
The remaining area of the piece of felt is:
There are of felt left over.
