Answer: 8 billion or 8,000,000,000

====================================================

Reason:

We start with $8 \times 10^9$ which is the same as $8.0 \times 10^9$

The exponent 9 tells us to move the decimal point 9 spots to the right. If the exponent was negative, then we'd move the decimal point to the left that many spaces.

So we go from 8.0 to 8,000,000,000.0 or simply 8,000,000,000 which is the number 8 billion

Side note: There are 9 zeros in 8,000,000,000

How to solve 16 * 12.5

Mariana [72]

Answer: 200

Step-by-step explanation:

First I would do it like this.

12.5

X. 16

—————-

6 times 5 is 0, carry the 3, 6 times 2 is 12 and add 3 from the other which is 15, put the 1 from the 15 to the one next to the 12. 6 times 1 is 6 plus 1 is 7 which now you have 750. 5 times 1 is 5, 2 times 1 is 2, 1 times 1 is 1. It should look like this now.

12.5

X 16

—————

750

+ 1250

——————-

Which is 8750 but wait. Where is the decimal? Well, there is only one number behind the decimal so it is 875.0 or 875.

What's the difference between 1,968 and 3,000? Check your answer using inverse operations.

kolbaska11 [484]

1968-3000 = - 1032 because 3000 -1032 = 1968

hope this will help you

PLEASE HELP I’ll give Brainliest

Sunny_sXe [5.5K]

Answer:

B. $\frac{R'T'}{RT} = \frac{15}{8}$

Step-by-step explanation:

The dillation implies that both triangles RST and R'S'T' are similar and satisfies the following relationships:

(i) $\frac{R'T'}{RT} = \frac{S'T'}{ST} = \frac{R'S'}{RS} = k$

(ii) $k > 1$ (Enlargement)

There, the only option that fulfills this requirements is B. The correct answer is $\frac{R'T'}{RT} = \frac{15}{8}$ .

Evaluate the geometric series or state that it diverges. one ninth 1 9plus+startfraction 7 over 81 endfraction 7 81plus+startfra

olasank [31]

The series converges, and its sum is 1/2.

If r > 1, the series is divergent. If r < 1, the series is convergent. In our sequence, r, the common ratio we multiply by to get the next term, is 7/9; therefore it is convergent.

To find the sum of a convergent series, we use the formula
a/(1-r), where a is the first term and r is the common ratio. We then have
1/9÷(1-7/9) = 1/9÷2/9 = 1/9×9/2 = 1/2
