there are about 25000000000 red boold cells in the average adult. About how many adult would it take to have a total googol of r

IRISSAK [1]

A googol is 1.0*10^100. there are 25000000000 RBC in the average adult.
The number of adults equals
1.0*10^100 / 25000000000
=400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
(=10^100/(25*10^9)=4*10^89)

Harry solves the equation 1/3t = 15. He says the solution is 30. Is his answer correct? Fill in the blanks to explain how Harry

aksik [14]

Harry can first substitute 30 for t

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

Since, 10 is not equal to 15, Harry's solution is not correct.

Solution:

Given that,

Harry solves the equation:

$\frac{1}{3}t = 15$

He says the solution is 30

We have to check if his answer is correct or not

Fill in the blanks to explain how Harry can check whether his solution is correct

Harry can first substitute 30 for t

$\frac{1}{3} \times 30 = 15$

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10

$10\neq 15$

Since, 10 is not equal to 15, Harry's solution is not correct

Correct solution:

$\frac{1}{3}t = 15\\\\t = 15 \times 3\\\\t = 45$

Thus correct solution is 45

the diameter of a pearl is about 4×10-¹⁴ cm and the diameter of an atom is about 10-¹¹ m. how much larger than an atom is a pear

serious [3.7K]

Answer:

The diameter of an atom is 25000 times the diameter of a pearl.

Step-by-step explanation:

Given that,

The diameter of a pearl is $4\times 10^{-14}\ cm$

The diameter of an atom is $10^{-11}\ m=10^{-9}\ m$

Taking the ratio,

$\dfrac{\text{diameter of an atom}}{\text{diameter of a pearl}}=\dfrac{10^{-9}\ m}{4\times 10^{-14}\ m}\\\\=25000$

So, the diameter of an atom is 25000 times the diameter of a pearl.
