When rounding to.the nearest hundred are you to add or subtract?

2 answers:

6 0

Basically you don't really do either, mostly because when your rounding you mostly just look at the number your rounding to. okay so say your number is like 127 you would round to 100 because your number would've been below 150. And we know that five is the middle of every thing. 10 and the whole number system is made up of tens. So when you have to choose to round you have to go up to the next ten so say your number is 27 since it's above 5 you would round to 30. So if you have 127 it's below the 5 mark (which would be 150) so you would round to 100 because it's below that mark.

Answer:

When you round to the nearest hundred:

150 or higher turns into 200, so you'd do add.

But when it's 149 or lower, you simply subtract it by 49.

Which expression is equivalent to (x^6×x^10/×^-3)^2 and why?

mixer [17]

Answer:

The solution for the given expression is $x^{38}$ , i.e option C

Step-by-step explanation:

Given expression as :

$(\dfrac{x^{6}\times x^{10}}{x^{-3}})^{2}$

Now, From the common radix method

∵ In multiplication of radix , if the radix is same , then power is added

I.e $x^{6}\times x^{10$ = $x^{6+10}$

Or , $x^{6}\times x^{10$ = $x^{16}$

Now, The expression can be written as

$(\frac{x^{16}}{x^{-3}})^{2}$

And In Division of radix , if the radix is same , then power is subtracted

So, $\frac{x^{16}}{x^{-3}}$

Or, $x^{16 - (-)3}$

Or, $x^{16 + 3}$

or, $x^{19}$

∴ The expression is now

$(x^{19})$ ²

Now, again this is written as

$x^{19}$ × $x^{19}$

I.e here again the radix is same and in multiple for, so, power is added

∴ $x^{19}$ × $x^{19}$ = $x^{19+19}$

I.e $x^{19}$ × $x^{19}$ = $x^{38}$

Hence The solution for the given expression is $x^{38}$ , i.e option C . Answer

Find the next two numbers in the pattern. 12,500, -2500, 500, -100

iren2701 [21]

Let's find the difference between every two numbers. Let's start with 12,500 and -2500. We know this is a multiplication or division problem because of every other number being negative.

-2500/12,500=-0.2; let's see if the product to -2500 and -0.2 is 500. -0.2×-2500=500 500×-0.2=-100; since you only have to multiply the previous number by -.2, let's find the next two numbers.

-100×-0.2=20 20×-0.2=-4

So, the next two numbers in the pattern are 20 and -4.

egoroff_w [7]

Answer:

Step-by-step explanation:

The population size is everybody running the race. It does not include people watching the race and it is not confined to just the 20 people the researcher talked to.

If it doesn't limit itself to the 20 people, then the 5 and 12 and 3 people are also too limiting.

Find the GCF and LCM of 217x328x11 and 213x345x74and explain your reasoning.

AfilCa [17]

Answer:

Given expressions are,

217 x 328 x 11

213 x 345 x 74,

Since, 217 = 7 × 31

328 = 2 × 2 × 2 × 41,

11 = 1 × 11,

So, we can write, 217 x 328 x 11 = 7 × 31 × 2 × 2 × 2 × 41 × 1 × 11

Now, 213 = 3 × 71

345 = 3 × 5 × 23,

74 = 2 × 37,

So, 213 x 345 x 74 = 3 × 71 × 3 × 5 × 23 × 3 × 5 × 23

Thus, GCF ( greatest common factor ) of the given expressions = 1 ( because there are no common factors )

We know that if two numbers have GCF 1 then their LCM is obtained by multiplying them,

Hence, LCM ( least common multiple ) of the given expressions = 217 x 328 x 11 x 213 x 345 x 74
