Answer:
4440 or 4400
Step-by-step explanation:
To round 4435 to the nearest 10 we need to look at the number to the right of the 10, if it is a 1-4 we round down, if it is a 5-9 we round up. in this case the 3 is the ten and the 5 is the number to the right. Since it is in the numbers 5-9 we will round up. the nearest 10 above 35 is 40 so the new number will be 4440. We will repeat the process for rounding to the nearest hundred just with the hundred number which is a 4. the number to the right of the hundred is a 3 which means we will round down. the nearest hundred below 435 is 400 so the new number is 4400.
I hope this helps and please let me know if there is any further confusion or questions I would be happy to help!

(a+b)(a-b)
Step-by-step explanation:
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
Yes, the two ratios are proportional to each other. The multiplier from the first ratio to the second ratio is 3. For example, 4.2 x 3 = 12.6 and 1.5 x 3 = 4.5. Basically, to figure out if two ratios are proportional to each other, just divide the smaller number into the bigger number for both corresponding numbers. If they're the same ---> Proportional. If they're not the same ---> Not Proportional
Answer:
1) 11
2) 4
Step-by-step explanation:
1) It is 11 because in the first row we ignore the 0 since it is referring to the first digit, so the first row has 7. In the second row, we ignore the one so it would be 4 because the 9, or would be 19, is above 18.
2) It is 4 because there is one person over 65. In the second row we ignore the 7 and there are 3 people in the 7 row.
