Round 71290 to the nearest 10 what's the answer?

1 answer:

6 0

71290 because the ones are 0 and zero is lower than 5
so it wouldn't add anything to the tens

the rule is if the number is more than 5+ it will add 1 to the next number
for example if we have this number 189 and we want to round it to the nearest 10 ..
we will see the ones place is it more than 5+ ? YEAH bcz its 9 ...
so 9 will add one to the tense and the answer will be 190 :)

hope you got the point .

Without using logarithm tables, find the value of x given that: 2log2/3 = 1/2logx - log 18 + log 16

sweet-ann [11.9K]

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

Given:

$2log(\frac{2}{3})=\frac{1}{2}log(x)-log(18)+log(16)$

Use the Power Rule Law:

$log(\frac{2}{3}^2)=log(x^{1/2})+log(16)-log(18)$

Use the Quotient Rule Law:

$log(\frac{4}{9})=log(\sqrt{x})+log(\frac{16}{18})$

Use the Product Rule Law:

$log(\frac{4}{9})=log(\frac{16\sqrt{x}}{18})$

Simplify:

$log(\frac{4}{9})=log(\frac{8\sqrt{x}}{9})$

$\frac{4}{9}=\frac{8\sqrt{x}}{9}$

$4=8\sqrt{x}$

$\frac{4}{8}=\sqrt{x}$

$\frac{1}{2}=\sqrt{x}$

$\frac{1}{4}=x$

You have to subtract 5x since its positive bring it to the other side then divide with negative one with everything which you get you y = 5- 5x
the slope is five over one
the y intercept is 5

Solve the inequality and then graph it t-3 < -2

SSSSS [86.1K]

Hi there!

Answer:

t<1

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 3 from both sides of an equation.

$t-3+3$

And then, you add/subtract from left too right.

$(-2)+3=-1$

It change negative to positive sign.

Final answer is t<1

Hope this helps!
