Answer:

Step-by-step explanation:
We see that this is a rectangle triangle, and that the ZY side is the hypotenuse.
It's length is then square root of the sum of the squares of the other sides:

So, in this case:

The 8 and 3 numbers are easy to get from the graphic... and the order doesn't matter (8² + 3² = 3² + 8²).
That's an easy rule to remember.
I hope it helps.
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.
<span>Each piece length will be 1/8 part of the whole piece, so as the total length is 9 yards then we will have that the lengh of each piece is one and eighth yard.
The division expression is as follows:
Piece length = 9 * 1/8 = 9/8 = (8+1)/8 = 8/8+1/8 = 1 + 1/8 = 1 + 0.125 = 1.125 yards</span>
Answer:
28.5
Step-by-step explanation:
Take the total # of pages to be READ, 128.5, divide by the # of days, 4.5, your answer is pages to read per day. 128.5/4.5 =28.55. Check your answer by multiplying 28.55x4.5 = 128.5
Hope this helps.

Answer:
1260
Step-by-step explanation:
The least common multiple is the smallest positive number which is a multiple of the two. This means 84, 36, and 15 divide into it evenly. To find the multiple:
- We list the prime factors of each number.
- We note how many times each occurs.
- We multiply each factor the greatest number of times it occurs in a number.
84: 2*2*3*7
36: 2*2*3*3
15: 3*5
LCM: 2*2*3*3*5*7= 1260
