Answer:
27 67 16 01 27 35 21 37 74 10
Step-by-step explanation:
Starting from the left, you pick two numbers together and skip two numbers if it is greater than 78.
Meaning:
27816 78416 01822 73521 37741 016312 68000 53645 56644 97892 63408 77919 44575
You pick [27] and leave 81 since it is greater than 78, the population number.
Then you pick [67] and leave 84 as it is also greater than 78.
Then you pick [16] and [01] but leave 82, as it is greater than 78.
Then pick [27], [35], [21], [37], [74] and [10] since they are all less than 78.
At this juncture, you have identified 10 numbers: 27 67 16 01 27 35 21 37 74 10
<span>I would tell my classmate to multiply the sum he is trying to find the percent from (122) by the percent itself so 122 X 0.42 which will give you 42% of 122 its really just about simple Multiplication and converting decimal places</span>
Answer:
Step-by-step explanation:
Solving for x means you have to factor. First factor out the GCF of 2 to get:
and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:
1, 18
2, 9
3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:
and
and
and
and
which finally simplifies to
No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
If rounding to the hundreds
To estimate round 324 and 285 to the closest hundred.
300 - 300
Then subtract 300 - 300 =
0
If rounding to the tens
To estimate round 324 and 285 to the nearest ten.
320 - 290
Then subtract 320 - 290 =
30
