Answer:

6 1/6

Step-by-step explanation:

Divide the numerator (19) by the denominator (6)

Write down the whole number result which in this case would be 3

Use the remainder as the new numerator over the denominator. This is the fraction part of the mixed number. which in this case is 1/6

therefore the answer is 6 1/6

nika2105 [10]

Answer:
Option A is correct
Difference of squares identity should be used to prove 49-4 =45
Step-by-step explanation:
Prove that : 49 - 4 = 45
Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.
Difference of the squares identity:

The density of silver is 10.5 g/cm. Find the volume of a silver bar if it’s mass is 950 g.

denis-greek [22]

Answer: The volume is 90.47 $cm^{3}$

Step-by-step explanation:

1. To solve this problem you need to use the formula for calculate the density, which is shown below:

$d=\frac{m}{V}$

Where $m$ is the mass and $V$ is the volume.

2. You must solve for the volume, as following:

$V=\frac{m}{d}$

3. Now, you must substitute the values of the mas and the density, which are given in the problem. Therefore, you have:

$V=\frac{950g}{0.5g/cm^{3}}\\V=90.47cm^{3}$

What is the answer to 2/3^5 divided by 2/3^1

lorasvet [3.4K]

Use the rules of indices

When they are dividing we subtract the exponents provided the bases are the same.

Since the bases are the same,

(2/3)^5 ÷ (2/3)¹

Will be

(2/3)^5-1

= (2/3)⁴

= 16/81

Hope this helps.

Which pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number?

laiz [17]

Answer:

Option C, D, E

Step-by-step explanation:

To find : Which pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number?

Solution :

We divide large number by smaller number to get the required answer,

A) $\frac{2.01\times 10^7}{4.25\times 10^6}=4.7294\approx 4$

B) $\frac{5.97\times 10^4}{3.12\times 10^3}=19.1346153846\approx 19$

C) $\frac{4.91\times 10^6}{5.09\times 10^3}=9365.4033\approx 9365$

D) $\frac{8.21\times 10^{-3}}{4.13\times 10^{-4}}=19.8789\approx 20$

E) $\frac{6.22 \times 10^{-7}}{2.94\times 10^{-8}}=21.156462585\approx 21$

Option C, D and E pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number.
