Answer:

0.063 mg

Step-by-step explanation:

1 gram equals to 1000 milligrams

so we converte the answer to milligrams

6.3 x 10^-5 equals to 0.000063

So we converte

1 gram 1000 mg

0.000063g =

0.000063 X 1000 = 0.63 mg

answer is 0.063 mg

Answer:

Symmetric property

Step-by-step explanation:

The symmetric property states that if a = b, then b = a. In other words, if one side of an equation is equal to the other side, then the two sides are interchangeable. This is symbolized by the following equation: a = b if and only if b = a. The symmetric property is used to solve equations with two variables.

Answer:

The answer is Symmetric Property.

The solution of the given expression is-

[tex]7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}[/tex]

We must first transform mixed fractions into improper fractions before we can subtract them.

Let's transform  [tex]7\frac{1}{5}[/tex]  it into an improper fraction :

[tex]7 \frac{1}{5} = \frac{(7 * 5 + 1)}{5} = \frac{36}{5}[/tex]

Let's change [tex]5\frac{1}{4}[/tex]  into an improper fraction now:

[tex]5\frac{1}{4} = \frac{(5 * 4 + 1)}{4} = \frac{21}{4}[/tex]

We can now subtract the fractions:

To subtract fractions, we need to find a common denominator. The least common multiple or the LCM of 5 and 4 is 20.

Converting the fractions to have a common denominator of 20:

(36/5) * (4/4) = 144/20

(21/4) * (5/5) = 105/20

So the subtraction will be as follows:

[tex]\frac{36}{5} -\frac{21}{4} =\frac{(36*4)+(21*5)}{4*5} =\frac{144-105}{20}=\frac{39}{20}[/tex]

Therefore, [tex]7\frac{1}{5} -5\frac{1}{4}[/tex] is equal to  [tex]\frac{39}{20}[/tex] or,  [tex]1\frac{19}{20}[/tex] .

The solution of the given expression is-

[tex]7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}[/tex]

Answer:

Starting with 2 pennies, Kelly adds 2 more pennies to her penny jar every day. To find out how many pennies she will have on Day 10, we can calculate the total number of pennies accumulated.

On Day 1, she has 2 pennies.

On Day 2, she adds 2 more pennies, bringing the total to 2 + 2 = 4 pennies.

On Day 3, she adds 2 more pennies, bringing the total to 4 + 2 = 6 pennies.

This pattern continues, with 2 additional pennies added each day.

We can summarize the pattern as follows:

Day 1: 2 pennies

Day 2: 4 pennies

Day 3: 6 pennies

Day 4: 8 pennies

Day 5: 10 pennies

Day 6: 12 pennies

Day 7: 14 pennies

Day 8: 16 pennies

Day 9: 18 pennies

Day 10: 20 pennies

Therefore, on Day 10, Kelly will have a total of 20 pennies in her penny jar.

 Given that a circle has a diameter of 8 inches and we are required to find its area using 3.14 as pi.  

We know that the formula for calculating the area of a circle is A = πr², where A is the area, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.  

Since we are given the diameter of the circle, we can calculate its radius using the formula:  radius (r) = diameter/2  

Therefore, the radius of this circle is:  r = 8/2 = 4 inches  

Now, we can calculate the area of the circle using the formula:  A = πr²  Substituting the value of r, we get:  A = 3.14 x 4²  A = 3.14 x 16  A = 50.24 square inches  

Therefore, the area of the circle is 50.24 square inches.

The answer is:

The formula for the circle's area :

where :

We know the diameter, but the radius is one-half of that, so the radius is :

To find the x-intercept, we set y = 0 and solve for x:

0 = 5 + x

Subtracting 5 from both sides:

x = -5

Therefore, the x-intercept is -5.

To find the y-intercept, we set x = 0 and solve for y:

y = 5 + 0

Simplifying:

y = 5

Therefore, the y-intercept is 5.

The x-intercept is (-5, 0).

The y-intercept is (0, 5).

Answer:

x: -5,0
y: 0,5

Step-by-step explanation:

y=0

0=5+x

x=-5

In mathematics, the terms "x-intercept" and "y-intercept" refer to points where a graph intersects the x-axis and y-axis. They are important concepts in the study of functions and graphs.

The x-intercept is the point at which a graph crosses or intersects the x-axis. It represents the value of x when y is equal to zero. In other words, it is the value of x when the function or equation is satisfied with y = 0. The x-intercept is often denoted as (x, 0), where "x" is the x-coordinate of the point.

Similarly, the y-intercept is the point at which a graph crosses or intersects the y-axis. It represents the value of y when x is equal to zero. Geometrically, it is the point on the graph where x = 0. The y-intercept is often denoted as (0, y), where "y" is the y-coordinate of the point.[tex]\hrulefill[/tex]

(1) - Finding the x-intercept

To find the x-intercept, you set y equal to zero and solve the equation for x.

[tex]y=5+x\\\\\\\text{Let y=0}\\\\\\\Longrightarrow 0=5+x\\\\\\\Longrightarrow \boxed{x=-5}[/tex]

Thus, the x-intercept is (-5,0).

(2) - Finding the y-intercept

To find the y-intercept, you set x equal to zero and solve the equation for y.

[tex]y=5+x\\\\\\\text{Let x=0}\\\\\\\Longrightarrow y=5+0\\\\\\\Longrightarrow \boxed{y=5}[/tex]

Thus, the y-intercept is (0,5).[tex]\hrulefill[/tex]

We can check this answer using a graphing calculator. Simply type in the given function and see were the function crosses each axis. Refer to the attached image.

The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".

To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.

The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.

The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100
