Final answer:

Leah can make 46 full bags of toy cars to sell at the flea market when placing 6 toys in each bag out of her 280 toy cars, with 4 toys remaining unsold.

Explanation:

Leah has 280 toy cars and wants to sell them in gift bags, with 6 toys in each bag. To find out how many full bags she can sell, we need to divide the total number of toy cars by the number of toys per bag.

The calculation would be 280 ÷ 6 = 46 R4. This means Leah can make 46 full bags of toys and there will be 4 toys left over. Since she only sells full bags, the 4 extra toys will not be sold.

Answer:

93 h

Step-by-step explanation:

P = 4300eᵏᵗ

1. Calculate the value of k

lnP = ln4300 + kt

ln5800 = ln4300 + k(40 h)

8.666 = 8.366 + 40k h

8.666 - 8.366 = 40k h

0.299 = 40 k h

k= 0.299/40 h = 7.481 × 10⁻³ h⁻¹

2. Calculate the time for the population to double

2 × 4300 = 4300eᵏᵗ

2 = eᵏᵗ

ln2 = kt

t = ln2/k = ln2/(7.481 × 10⁻³ h⁻¹) = 93 h

It takes 93 h for the population to double.

Solve for x.

20% × x = 35

0.2x=35

x=175

answer: 175

Answer: 175

Step-by-step explanation: We can change this problem to mean the same thing but it will say 20% of what number is 35.

To answer the question 20% of what number is 35, we translate the question into an equation. First we have 20% which we need to write as a decimal and remember to write 20% as a decimal, we move the decimal point 2 places to the left and we get 0.20.

Next we have "of what number" that's times x, "is 35" = 35. Now we have the equation (.20)(x) = 35.

Not to solve for x, since x is being multiplied by .20, we need to divide by .20 on both sides of the equation. On the left side of the equation the .20's cancel and we have x. On the right side of the equation we have 35 divided by .20 which is 175.

This means that 20% of 175 is 35.

Answer:

The x-coordinate gives the solution of the original equation.

Step-by-step explanation:

Let us assume that the original equation is 2x = x + 5 ........... (1) and the solution that this equation has will be x = 5.

But, if we solve the equation by graphing each side as a separate line i.e. y = 2x and y = x + 5, then solving those two equations we get the solution x = 5 and y = 10.

Therefore, the x-coordinate i.e. x = 5 gives the solution of the original equation (1). (Answer)

Final answer:

Each apple costs 41 cents when a dozen apples are bought for $4.92, determined by dividing the total cost by the number of apples.

Explanation:

The question asks to find the cost per apple when a dozen apples are purchased for $4.92. To find the cost per individual apple, you divide the total cost by the number of apples. There are 12 apples in a dozen, so:

$4.92 ÷ 12 apples = $0.41 per apple

So, each apple costs 41 cents. This exercise of finding the individual cost from a total is an example of a ratio used in basic arithmetic, often taught in middle school mathematics.

Step-by-step explanation:

''Step two involves preparing a list of suitable questions for the dealers you wish to visit. For example, if you want rustproofing, was it factory-installed or dealer-installed? Are there charges for documents like taxes and tags? Is there a dealer advertising fee? These charges won't appear on a factory invoice, but you will pay for them.''

Answer: Yes, it does, because each input value has an unique output value.

Step-by-step explanation:

First, you need to know when a relation is considered a function.

By definition, a relation is a function if an only if each input value has one and only one output value.

It is important to remember that the input values are the values of "x" and the output values are the values of "y".

Then, in this case, you can observe in the graph attached ( which shows the data for Camille’s puppy), that each x-value (Weeks) has an unique y-value (Weight in pounds).

Therefore, based on this and keeping on mind the explained before, you can conclude that the data for Camille’s puppy shows a function.

Step-by-step explanation:

Given equation is:

[tex]3x^2+3x+5 = 0[/tex]

We will use the quadratic formula for solving the given equation

The quadratic formula is:

[tex]x = \frac{-b+\sqrt{b^2-4ac}}{2a}\ \ \ ,\ \ \ x = \frac{-b-\sqrt{b^2-4ac}}{2a}[/tex]

Here,

a = 3

b = 3

c = 5

[tex]x = \frac{-3+\sqrt{(3)^2-4(3)(5)}}{2(3)}\ \ \ ,\ \ \ x = \frac{-3-\sqrt{(3)^2-4(3)(5)}}{2(3)}\\x = \frac{-3+\sqrt{9-60}}{6}\ \ \ ,\ \ \ x = \frac{-3-\sqrt{9-60}}{6}\\x = \frac{-3+\sqrt{-51}}{6} \ \ \ , \ \ \ \ x = \frac{-3-\sqrt{-51}}{6}[/tex]

As we know

[tex]i = \sqrt{-1}[/tex]

So,

[tex]x=\frac{-3+\sqrt{51*-1}}{6} \ \ \ , \ \ \ \ x = \frac{-3-\sqrt{51*-1}}{6}\\x=\frac{-3+(\sqrt{51}*\sqrt{-1})}{6} \ \ \ , \ \ \ \ x = \frac{-3-(\sqrt{51}*\sqrt{-1})}{6}\\x = \frac{-3+\sqrt{51}i}{6}\ \ \ \ AND\ \ \ \ x = \frac{-3-\sqrt{51}i}{6}[/tex]

Hence,

The solution is:

[tex]x = \frac{-3+\sqrt{51}i}{6}\ \ \ \ AND\ \ \ \ x = \frac{-3-\sqrt{51}i}{6}[/tex]

Answer:

22

Step-by-step explanation:

21.6 would round up because 6 is closer to 10 than it is 0

The number 21.6 rounded to the nearest whole number is 22.

Rounding off of a number is defined as the simplification of the number by keeping the value of the number same but is made closer to the next number.

Rounding can be done for whole numbers as well as decimals.

Given a number 21.6.

We have to round the number.

Here the first digit after the decimal place is 6, which is greater than 5.

So we have to add 1 to the last digit in the whole part.

So 21.6 is rounded to 22 to the nearest whole number.

Hence the correct number is 22.

Solution:

The Given Equation is in Slope - Point Form i.e

[tex]y=mx+c[/tex]

Where,

[tex]m=slope\\\\c=y-intercept[/tex]

On Comparing the given equation with above we get

[tex]slope=m=3\\\\y-intercept =6[/tex]

Now we Know that

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

For x-intercept

Put y = 0 in

[tex]y=3(x+2)[/tex]

[tex]0=3x+6\\\\3x=-6\\\\\therefore x=\dfrac{-6}{3}=-2[/tex]

Step-by-step explanation:

The interest is 5.5% yearly and it is simple interest.

Now, if we consider a deposit of $575 into the bank account that earned 5.5% simple interest each year, then after 2 and half years James will get interest only for 2 years as the 3rd year's interest will be added after the 3rd year.

Therefore, if no money was deposited into or withdrawn from the account, then after 2.5 years the sum will be

Answer:

12.5 centimeters per minute

Step-by-step explanation:

From the graph, the rate at which the diameter increasing would be inthe units of cm/min

The rate is basically the slope of the line. The slope (m) has formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where

[tex](x_1,y_1)[/tex]  is any point from the graph

and

[tex](x_2,y_2)[/tex]  is another point from the graph

Let's take the origin (0,0) as the first point and (4,50) as the second point. Now lets calculate the slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{50-0}{4-0}\\m=\frac{50}{4}\\m=12.5[/tex]

Thus, we can say:

The diameter of the hot air balloon is increasing at a rate of 12.5 centimeters per minute

Answer:

The measure of the angle is 64 degree.

The measure of the supplement is 116 degree.

Step-by-step explanation:

Let the measure of the angle be 'x'.

Given:

Supplement of the angle is 12 less than twice the measure of the angle.

Twice the angle means 2 times of the angle which is [tex]2x[/tex] and 12 less means 12 is subtracted from [tex]2x[/tex].

So, supplement of the angle = [tex]2x-12[/tex]

Now, by definition of supplementary angles, if two angles are supplement of one another, then their sum is 180 degrees.

Therefore, the sum of the given angles = 180°

⇒ [tex]x+2x-12=180[/tex]

⇒ [tex]3x-12=180[/tex]

⇒ [tex]3x=180+12[/tex]

⇒ [tex]3x=192[/tex]

⇒ [tex]x=\frac{192}{3}=64\°[/tex]

The measure of the supplement = [tex]2(64)-12=128-12=116[/tex]

The measure of the angle is 64 degree.

The measure of the supplement is 116 degree.

Answer:

  The slopes of the lines are different.

Step-by-step explanation:

If you do convert the standard form equation to slope-intercept form, you get ...

  y = -x +5

You see that the slope of this line is -1, whereas the slope of the other line is +1. Both lines have a y-intercept of 5. It is the slopes that are different.

_____

You can determine this to be the case without converting the form of the equation if you have some practice with the various forms of the equation of a line.

In standard form, if the variable signs are the same, the slope is negative. Of course, in slope-intercept form, the sign of the slope is the sign of the coefficient of x.
