Oxana [17]

Answer:

Answer is 900.

Step-by-step explanation:

To find:

Increase #500 in the ratio 16:10

Solution:

New Number: Old Number = 16:10

We are given the old number as 500.

Let the new number after increase = $x$

Now, using the above ratio:

 $x$ : 500 = 16:10

$\dfrac{x}{500} = \dfrac{16}{10}\\\Rightarrow x = 500 \times \dfrac{16}{10}\\\Rightarrow x = 50 \times 16\\\Rightarrow x = 900$

Therefore, the increased value of 500 in the ration 16:10 is 900.

. 5.8x10 to the power of 7

Delvig [45]

PEMDAS means we do exponents before we multiply.

10 ^ 7 = 10,000,000

(10 * 10 * 10 * 10 * 10 * 10 * 10)

5.8 * 10,000,000

= 58,000,000
