Answer:

1,124 pennies.

Step-by-step explanation:

Let x represent the total amount of coins Christine's penny bank can hold.

We know that it is initially 1/5 full. So, the amount of coins in the bank is:

[tex]\frac{1}{5}x[/tex]

We know that she adds 562 pennies in it. So, we will add 562 to our expression:

[tex]\frac{1}{5}x+562[/tex]

And we know that after adding 562 pennies, the bank is now 7/10 full. Therefore:

[tex]\frac{1}{5}x+562=\frac{7}{10}x[/tex]

To find out how many coins the bank can hold, we will simply solve for x.

First, let's multiply both sides by 10 to remove the fractions:

[tex]10(\frac{1}{5}x+562)=10(\frac{7}{10}x)[/tex]

Distribute:

[tex]2x+5620=7x[/tex]

Subtract 2x from both sides:

[tex]5x=5620[/tex]

Divide both sides by 5:

[tex]x=1124[/tex]

Therefore, Christine's penny bank can hold a maximum of 1,124 pennies.

And we're done!

Answer:

12(d-6)

Step-by-step explanation:

Answer:

12n-72

Step-by-step explanation:

You would say 12(n-6) because the difference of a number would be n and the difference is 6. When it says 12 times, then you will multiply it by the numbers in the parentheses.          

1. The number of different triangular frameworks that Joe can make which have a longest side 7 meters long, using the rods he has in stock is 6 triangular frameworks.

2. The value of c cannot be less than 2 and Joe can't use a 1 meter rod.

3. The length ​triangular frameworks can't be modeled by a single function rule.

In Mathematics, the Triangle Inequality Theorem is represented by this mathematical expression:

b - c < a < b + c

Where:

a, b, and c represent the side lengths of this triangle.

By applying the Triangle Inequality Theorem to the side lengths of this triangle, we have:

c > b > a

Part 2.

Next, we would investigate for other values of c such as 8, 6, and 4;

8 > 7 > 6            6 > 5 > 4            4 > 3 > 2

8 > 7 > 5            6 > 5 > 3

8 > 7 > 4            6 > 5 > 2

8 > 7 > 3            6 > 4 > 3

8 > 7 > 2

8 > 6 > 5

8 > 6 > 4

8 > 6 > 3

8 > 5 > 4

Part 3.

Assuming the value of c is even, the number of different triangular frameworks can be modeled by [tex]\frac{(c-2)^2}{4}[/tex]. Assuming the value of c is odd, the number of different triangular frameworks can be modeled by [tex]\frac{(c-3)(c-1)}{4}[/tex].

Answer:

10 because if you multiply 5 times five you get 10

Answer:

  a) False

  b) True

Step-by-step explanation:

a) h(1) = 0/0, which is certainly undefined. There may or may not be a finite limit at that point, so the line x=1 is not necessarily a vertical asymptote.

The assertion that x=1 is necessarily a vertical asymptote is False.

__

b) h(2) = 4/0, another undefined value. However, we can be certain that the limit of h(x) as x → 2 is infinite, meaning the line x=2 will be a vertical asymptote.

The assertion that x=2 is necessarily a vertical asymptote is True.

Step-by-step explanation:

A line passing through two points

Given two points A(x1,y1) and B(x2,y2), the equation of the line passing through them is:

[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The question provides the points (1,0) and (1,0). Note both points are the same. They cannot be used because there is not a unique line passing through a single point.

We'll use the points (0,1) and (1,0) instead.

[tex]\displaystyle y-1=\frac{0-1}{1-0}(x-0)[/tex]

[tex]\displaystyle y-1=\frac{-1}{1}(x-0)[/tex]

[tex]\displaystyle y-1=-x[/tex]

Reducing:

[tex]\boxed{y=1-x}[/tex]

Answer:

The formula used for the average growth rate over time method is to divide the present value by the past value, multiply to the 1/N power and then subtract one. "N" in this formula represents the number of years.

Step-by-step explanation:

The given line passes through (0,10) and (2,0), so its slope is

[tex]\frac{10-0}{0-2}=-5[/tex]

Since perpendicular lines have negative reciprocal slopes, the slope of the line we want to find is 1/5.

Substituting into point-slope form,

[tex]y-2=\frac{1}{5}(x-1)\\\\y-2=\frac{1}{5}x-\frac{1}{5}\\\\\boxed{y=\frac{1}{5}x+\frac{9}{5}}[/tex]

The total volume of applesauce in a 6-pack is  (22 + 1/2) ounces.

We know that a single cotainer of apple sauce contains 3 + 3/4 ounces of applesauce.

Now, a 6-pack of applesauce has 6 containesr on it, then the total volume of applesauce will be 6 times the volume that we have above, so what we need to solve here is the following product:

Volume = 6*(3 + 3/4) oz = (6*3 + 6*3/4) oz

We can simplify that to:

(18 + 18/4) oz

And rewrite the fraction as: 18/4 + 16/4 + 2/4 = 4 + 1/2

Then the total volume is:

(18 + 4 + 1/2) ounces = (22 + 1/2) ounces.

Answer:

A quadratic function with imaginary roots will never intersect the x-axis, because imaginary numbers are not real numbers. Therefore, the graph of a quadratic function with imaginary roots will be a parabola that does not touch the x-axis.

Here is an example of a quadratic function with imaginary roots:

f(x) = x^2 + 2x + 5

The discriminant of this quadratic equation is b^2 - 4ac = 4^2 - 4 * 1 * 5 = -4. Because the discriminant is negative, the roots of the equation are imaginary.

The graph of this function is shown below: Attachment

As you can see, the graph does not intersect the x-axis. This is because the roots of the equation are imaginary, and imaginary numbers do not exist on the real number line.

In order to solve this equation, you must be able to use your substitution propertys. 5x+2y=11.91 and 3x+3y=11.34

Using the first equation, 2y=11.91-5x then y=(11.91-5x)/2. Then substitute.

Answer:

$26.8

Step-by-step explanation:

To find the discount, you turn the percentage of the discount into a decimal (.33) then multiply it by the original price (40)

$40 x .33 = 13.2

You then subtract the total to the original price of the item (40)

$40 - 13.2 = 26.8

So the discount price of the jacket would be $26.8

To find the measure of the geometry-big circle, we need to sum up the measures of all the arcs around the circle.

We are given the following measures:

[tex]\sf\:m\angle AB = 56 \\[/tex]

[tex]\sf\:m\angle BC = 59 \\[/tex]

[tex]\sf\:m\angle CD = 63 \\[/tex]

[tex]\sf\:m\angle DE = 63 \\[/tex]

[tex]\sf\:m\angle EF = 31 \\[/tex]

To find the measure of the geometry-big circle, we add up these measures:

[tex]\sf\:m\angle AB + m\angle BC + m\angle CD + m\angle DE + m\angle EF \\[/tex]

Substituting the given values:

[tex]\sf\:56 + 59 + 63 + 63 + 31 \\[/tex]

Simplifying the expression:

[tex]\sf\:272 \\[/tex]

Therefore, the measure of the geometry-big circle is 272.
