Answer:

400,000

Step-by-step explanation:

The given sum is 164,215+216,088

We simplify this to get:

164,215+216,088=380,303

The digit at the hundred thousand position is the rightmost 3.

The digit after it is 8.

Since 8≥5 we round up.

We add 1 to 3 to get 4 and replace all digits to the right with zeros.

We round to the nearest hundred thousand to get:

400,000

What is the value of the geometric sequence for which a1=10 and r=0.5?

tiny-mole [99]

The formula for an infinite geometric sequence is the following:

$S_{∞}= \frac{a_{1}}{1-r}$

Just substitute the values of $a_{1}$ and r into the formula.

$S_{∞}=\frac{10}{1-0.5}$
$S_{∞}=\frac{10}{0.5}$
$S_{∞}= 20$

Therefore, the answer is 20.

Determine the number of solutions for the equation 1 - 3(x - 2) = 7 - 3x

faltersainse [42]

I would say you have an infinite number of solutions for this equation. This is because when you expand the bracket on the left, you get 1 - 3x + 6 which is 7 - 3x, which is the same as on the right. The reason the solutions would be infinite is because they're multiplied by the same thing and added to the same thing, so they're always gonna be the same.

I hope this helps!
