What is the quotient of 4.644 x 10^8 and 6.45 x 10^3 expressed in scientific
notation?

Answers

Answer:

7.2 x 10^4

Step-by-step explanation:

The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is 7.2 x 10⁴.

What is the quotient of division?

The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation, is calculated as follows;

(4.644 x 10⁸) / (6.45 x 10³) = (4.644 / 6.45) x (10⁸ / 10³)

Calculating the division:

= 72,000

Now, we need to express the result in scientific notation. Move the decimal point to the left until there is only one non-zero digit to the left of the decimal point.

= 72,000

= 7.2 x 10⁴

So, the quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is approximately 7.2 x 10⁴.

How might the crisis in biodiversity lead to a food crisis for humans?

Answers

Answer:

Hi and heres your answer!

Step-by-step explanation:

The crisis of biodiversity will lead to a food crisis for humans because:

1.No varieties in certain foods like plants and animals that are healthy

2.The Less food there is,more animals go extinct which means humans will go extinct too.

and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

Find the measure of each angle indicated.

A D
A) 21°
C) 23°
E 25°
B) 80°
D) 20°

Answers

Let the missing Angle be " x "

We know that Measure of an exterior angle of a triangle is equal to sum of the opposite two interior angles,

that is :

x + 80° = 100°

x = 100° - 80°

x = 20°

value of missing angle = 20°

The area of a rectangle is 360 cm, and the length is 2 cm more than the width Find the width​

Answers

Answer: 18 cm

Explanation:

Let x = width (W)
Let x + 2 = length (L)

Area (A) = L*W
x(x+2) = 360
x^2 + 2x = 360
x^2 + 2x - 360 = 0
(x + 20)(x - 18) = 0
x + 20 = 0
x = -20
^^^ reject because distance can’t be negative
x - 18 = 0
x = 18 (width)

x + 2 = 20 (length)

Check:
A = L*W
360 = 20 * 18
360 = 360

The density of an object is calculated using the formula D=m/v where m
is the object's mass and V is its volume. Gold has a density of 19.3 g/cm^3”. What is
the volume of an amount of gold that has a mass of 96.5 g?
*If y’all can do this and show all the work that would be awesome! I have to show work to my teacher in order for her to grade it and I have a D in her class so please help!*

Answers

To find the volume of the amount of gold, rearrange the formula algebraically:

D = m/V
Multiply both sides by V:
D(V) = m/V (V)

DV = m
Divide both sides by D to isolate V
DV/D = m/D

V = m/D (this is the formula needed for volume).

Next, substitute the given values for density and mass:

V = 96.5g/19.3g/cm^3
V = 5 cm^3

Therefore, the volume of an amount of gold that has a mass of 96.5 g is 5 cm^3.

Looking at the two terms, 7a4b2c2 and 14abc6, what is the GCF do the coefficients?

Answers

Greatest Common Factor is also shortened as G.C.F . Greatest Common Factor can be used as the greatest or highest number that divides exactly into two or more numbers.

The GCF for the coefficients is 7. Option A is the correct option.

From the question, we are given two terms 7a4b²c² and 14abc⁶

The coefficient for 7a4b²c² = 7

The coefficient for 14abc⁶ = 14

Solving for the GCF,

The factors of 7 are: 1, 7

The factors of 14 are: 1, 2, 7, 14

Then the greatest common factor is 7.

Therefore, the GCF for the coefficients is 7 . Option A is the correct option.
