Answer:
D. 10/3
Step-by-step explanation:
6/7 6 divided by 7 = 0.86
proper- doesn't go over 1
3/10 3 divided by 10 = 0.30
proper - doesn't go over 1
4/5 4 divided by 5 = 0.8
proper- doesn't go over 1
10/3 10 divided by 3 = 3.33
improper- goes over 1
PROPER- When divided, <u>DOESN'T</u> go over 1 whole
IMPROPER- When divided, <u>DOES </u>go over 1 whole
A multiple is a number that can be gotten from multiplying a number by any number. For example, a multiple of 3 would have to be something that you can count by threes to get to. The same applies to 10, if you count by tens, any of those numbers that you get while counting by tens would be a multiple of 10.
Step 1 involves you listing out all the ways to multiply to 56, and then adding up those factors. For instance, the first row has 1 and 56 which add to 57 in the third column. The second row has -1 + (-56) = -57. The third row has 2+28 = 30. And so on. The idea is to fill out the table completely with the other ways to have factors of 56 added up. The table is shown in the attached image below.
------------------
Step 2 then uses the table to figure out which pair of factors (of 56) add to -15. This would be -7 and -8. In other words,
-7 plus -8 = -15
-7 times -8 = 56
We have found the right pair of numbers. In the table I have provided, this is shown as the highlighted yellow row.
------------------
Step 3 is then using those pair of numbers found in step 2 to set up the factorization. We would say that x^2-15x+56 factors to (x-7)(x-8). This is the same as (x-8)(x-7) as we can multiply two numbers in any order we want.
Answer:
False
Step-by-step explanation:
Two arcs are congruent if they have the same length and belong to the same circle or two congruent circles. if two central angles of a circle are congruent then they form congruent arcs.
Answer: 21 dollars was his bill before the tip
Step-by-step explanation: 4.20 is 20% of what he paid with no tip included. This means you can set up an equation like this.
4.20 = .2x This means that $4.20 is (is means =) 20% of (of means multiply) x (which is the unknown factor).
