What are Exponents?
Exponents are a shorthand way of representing repeated multiplication of a number by itself. They are indicated by a superscript number placed to the right and above the base number.
The superscript number represents the number of times the base number is multiplied by itself. For example, 2³ means 2 multiplied by itself three times, which equals 8.
Exponents are used to simplify large and small numbers, and are fundamental to algebraic and mathematical calculations. Exponents have several rules, such as the power of a power rule, product rule, quotient rule, and negative exponents rule.
10⁻³ can be evaluated as:
1 / 10^3 = 1 / 1000
Therefore, 10⁻³is equal to 1/1000 or 0.001.

Answer:
The graph showing the temperature change over time is missing.
Step-by-step explanation: The slope of the line in the graph is the rate of temperature change per minute.
1. Calculate the slope between for each of the 3 ranges listed. Slope is rise/run: Take two points at the upper and lower boundaries of each range. You should have three sets of points:
e.g., (0,100) and (340, 175); (345, 176) and (360, 180); finally (360,185) and (380, 200). I made these up, since there is no graph. but the x values, the time in minutes, correspond to the ranges requested.
If the slopes are diferent, then explain that the rate of temperature rise is different for each segment.
3. Time is 360 + 60 = 420, temperature is 80: (420,80)

Answer:
42 6/7
Step-by-step explanation:
For me what i usually do is i convert the mixed number into a fraction, which for example:
Example and Explanation: Step 1
so since the number 7 is the denominator and the 2 is the mixed number, we can multiply these numbers, 2 x 7 = 14, then we add our numerator which in this case, is one, 14 + 1 = 15, and since the denominator stays the same, our fraction now is 15/7. We do the same for the others:
3 3/4:
3 x 4 = 12 + 3 = 15 = 15/4
5 1/3:
5 x 3 = 15 + 1 = 16 = 16/3
Now that they are all fractions we can finally do the multiplication
Multiplying Fractions: Step 2
Multiplying fractions does not require that the fractions have the same denominator. Instead, the numerators are multiplied with each other and the denominators are multiplied with each other. However, the resulting fraction may not be in lowest terms so it may need to be reduced. So since this is a three step multiplication problem, we will multiply two fractions first.
In this case I chose 15/7 x 15/4. so we just multiply from there, 15 x 15 = 225, and 7 x 4 = 28. So our fraction is 225/28, now we will multiply the other fraction: 225/28 x 16/3 which comes out to 3,600/84. Wow, thats a big number, now its time to..
Reduce: Step 3
This fraction is far too big to be a proper answer, so we will reduce, also known as simplifying.
Find the Greatest Common Factor (GCF) of 3600 and 84, if it exists, and reduce our fraction by dividing both numerator and denominator by it. GCF = 12,
=3600÷1284÷12=3007
Converting to a mixed number using long division with remainders for 300 ÷ 7.
300÷7=42r6
Therefore:
300/7 = 42 6/7

What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
We know a ratio between a and b can be written as a : b, a/b or a to b.
From the given information the ratio of rows of corn to beans is,
corn/beans = 13/12 Or 13 : 12 Or 13 to 12.
The ratio of rows of lettuce to the total number of rows in the garden is,

Warren has 40 coins (all nickels, dimes, and quarters) worth $4.05. He has 7 more nickels than dimes. How many quarters does Warren have?
Please provide a detailed explanation and steps on how to do
If he has 7 more nickels than dimes. The number of quarters that Warren have is 7.
How to determine the number of quarters?Let coins be:
n + d + q = 40
Where;
n = nickels
d =dimes
q = quarters
Hence,
.05n + .10d + .25q = 4.05
n = d + 7
Substitute (d+7) for n
(d+7) + d + q = 40
2d + q = 40 - 7
2d + q = 33
q = (33-2d)
So,
.05(d+7) + .10d + .25q = 4.05
.05d + .35 + .10d + .25q = 4.05
15d + .25q = 4.05 - .35
.15d + .25d = 3.70
Substitute (33-2d) for q
.15d + .25(33-2d) = 3.70
.15d + 8.25 - .5d = 3.70
.15d -.5d = 3.70 - 8.25
-.35d = -4.55
Divide both side by -/35d
d = -4.55 / -.35
d = 13 dimes
Nickels
n = d+7 where d is 13
n = 13 + 7
n = 20 nickels
Quarters
q = (33-2d)
q = 33 - 2(13)
q = 33 - 26
q = 7 quarters
Therefore 7 is the quarters.

What is a polar coordinate?The distance from a point to the origin (r) and the angle this line makes with a fixed line (Θ) are the two coordinates that specify where a point is located in a plane.
The radius of circle is 3 units.
The angle in the polar coordinate measured clockwise is considered negative and measured anticlockwise as positive.
In order to get the position of the angle from the x-axis the angle should be added by 2π as
Θ = 2π-5π/3
Θ = π/3
The angle is calculated clockwise.
From the diagram point, A represents the angle π/3.

How to calculate the volume of the new packaging?To calculate the volume of the new package we must perform the following procedure:
\(V = \pi r^{2} h\)
According to the above, we must substitute the values of the radius and the height to obtain the volume of the new package. If we increase the diameter by 2 in, then the new diameter will be 9.8 in. On the other hand, the radius will be:
9.8 in / 2 = 4.9 in

What is the w-intercept of the line of fit and its meaning in terms of the scenario?
4.75; a puppy who is just born is predicted to weigh 4.75 ounces
4.75; for each additional day after the puppy is born, its weight is predicted to increase by 4.75 ounces
0.5; a puppy who is just born is predicted to weight 0.5 ounces
0.5; for each additional day after the puppy is born, its weight is predicted to increase by 0.5 ounces
The correct answer is: 4.75; a puppy who is just born is predicted to weigh 4.75 ounces.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The equation of the line of fit is w = 4.75 + 0.5d, where w is the weight of the puppy in ounces and d is the age of the puppy in days.
The w-intercept of the line of fit is the value of w when d = 0, that is, the predicted weight of a puppy when it is just born.
From the equation, we see that when d = 0, we have:
w = 4.75 + 0.5(0) = 4.75
Therefore, the w-intercept of the line of fit is 4.75 ounces, and its meaning in terms of the scenario is that a puppy who is just born is predicted to weigh 4.75 ounces.

Solve the equation for all exact solutions where appropriate. Round approximate answers in degrees to the nearest tenth. Write answers using the least possible nonnegative angle measures. sin cos 0 - sin = 0 Choose the correct answer below. O A. {90°n, where n is any integer; B. {270°n, where n is any integer} C. {180°n, where n is any integer} OD. {0°}
To solve the equation sin(cos(0)) - sin(0) = 0, we first observe that cos(0) = 1. Substituting this value, we get sin(1) - sin(0) = 0. Since sin(0) = 0, we have sin(1) = 0.
The solutions to sin(x) = 0 are x = nπ, where n is an integer. Therefore, the only solution to the given equation in the interval [0,360°] is 0°.
However, if we consider all possible values of x, then the solutions are given by x = 180°n, where n is any integer. This is because sin(x) = sin(180° - x), and so sin(180°n + x) = sin(x) for all integers n and all angles x. Therefore, the answer is (C) {180°n, where n is any integer}.

The value of the 10% trimmed mean is approximately 1.3027. To calculate the 10% trimmed mean, we need to trim off the lowest and highest 10% of the data and then find the mean of the remaining values.
First, let's sort the data in ascending order:
0.2, 0.21, 0.26, 0.3, 0.33, 0.41, 0.54, 0.57, 1.41, 1.7, 1.84, 2.2, 2.26, 3.06, 3.24
Next, we calculate the number of values to trim from each end:
10% of 15 (total number of values) = 0.1 * 15 = 1.5
Since we can't remove half a value, we round up to the nearest whole number, which is 2.
Now, we remove the two lowest and two highest values:
0.26, 0.3, 0.33, 0.41, 0.54, 0.57, 1.41, 1.7, 1.84, 2.2, 2.26
Finally, we calculate the mean of the remaining values:
(0.26 + 0.3 + 0.33 + 0.41 + 0.54 + 0.57 + 1.41 + 1.7 + 1.84 + 2.2 + 2.26) / 11 = 14.33 / 11 ≈ 1.3027
Rounding to four decimal places, the value of the 10% trimmed mean is approximately 1.3027.

l = length
w = width
If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.
Solve:
**Disclaimer** I assume that the length is [3 feet longer than twice its width] because a [yard] would not use length to measure it. If it was, then you may refer to my answer. If it was not, then you may tell me and I will redo it.
Let x be the width
Let 2x + 3 be the length
Given information
Perimeter = 48 ft
width = x
length = 2x + 3
Given expression deducted from the question
Perimeter = 2 (l + w)
Substitute values into the expression
48 = 2 (2x + 3 + x)
Combine like terms in the parentheses
48 = 2 (2x + x + 3)
48 = 2 (3x + 3)
Expand parentheses and apply the distributive property
48 = 2 · 3x + 2 · 3
48 = 6x + 6
Subtract 6 on both sides
48 - 6 = 6x + 6 - 6
42 = 6x
Divide 6 on both sides
42 / 6 = 6x / 6
x = 7

Mrs. Ellis is shopping for school
supplies with her children. Hansen
selected 3 one-inch binders and 2 two-
inch binders, which cost a total of $20.
Pam selected 3 one-inch binders and 5
two-inch binders, which cost a total of
$32. How much does each size of
binder cost?
Answer:
Each one-inch binder costs $2.67 and each two-inch binder costs $6.
Step-by-step explanation:
Let's call the cost of a one-inch binder "x" and the cost of a two-inch binder "y".
From Hansen's purchase, we know that 3x + 2y = $20.
From Pam's purchase, we know that 3x + 5y = $32.
We can use these two equations to solve for the cost of each size of binder. If we subtract the first equation from the second, we get:
2y = $32 - $20 = $12
So, y = $6, which is the cost of a two-inch binder.
Next, we can plug this value back into either of the original equations to find the cost of a one-inch binder:
3x + 2($6) = $20
Expanding the right side, we get:
3x + $12 = $20
Subtracting $12 from both sides, we get:
3x = $8
Finally, dividing both sides by 3, we find that:
x = $2.67
So, each one-inch binder costs $2.67 and each two-inch binder costs $6.
