Answer:
Step-by-step explanation:
Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.
15% of 52 is indeed 7.8. $7.80 is the discount that is to be SUBTRACTED from the regular price ($52). Adding $7.80 to $52 is incorrect.
Also, 52 + 7.8 - 59.8 is incorrect: it's not an equation (but should be one), and we should be subtracting $7.80 from $52.

Answer:
6,400
Step-by-step explanation:
d=16t^2
t=20
Replace t with 20 because 20 = second
d=16(20)^2
d=16(400)
d=6,400
the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.
The two triangles below are similar. Use scale factor to find x

What is the sum of -2x³ + x-3 and x³ - 3x - 4?
(a) Show your work.
(b) Is the sum of -2x³ + x-3 and x³ - 3x - 4 equal to the sum of x³ - 3x - 4 and
-2x³ + x-3? Explain your answer.
Answer:
Step-by-step explanation
For the first sum you nee to find the same coefficient or add or subtract a number
\(-x^3 -2x -7\)
This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.
The next sum we have to simplify both numerals so we know if both sum’s answer are
\(-x^3 -2x -7-x^3 -2x -7\)
After simplifying them, both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Step-by-step explanation:
b will be the number of blue beads for the bracelet.
The number of red beads will be represented as b + 7.
Determine the expression for the total number of beads.
Then we can written it as,
= b + (b +7)
= 2b + 7.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Question: What is the value of r.
Mean, Median, Mode, Range
Objective: Identify the mean, median, mode, and range in application problems
Directions: Watch the following video. Then read the lesson and take notes before completing the lesson review.
Introduction
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list. Mean, median, and mode are measures of central tendency and are three different ways of expressing averages of a set of data.
Mean: The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set. The mean is also called the average.
Example:
Data Set = 2, 5, 9, 3, 5, 4, 7
Number of Elements in Data Set = 7
Mean = ( 2 + 5 + 9 + 7 + 5 + 4 + 3 ) / 7 = 5
Median: The "Median" of a data set is dependent on whether the number of elements in the data set is odd or even. First, reorder the data set from the smallest to the largest then if the number of elements is odd, then the Median is the element in the middle of the data set. If the number of elements is even, then the Median is the average of the two middle terms.
Example: Odd Number of Elements
Data Set = 2,5,9,3,5,4,7
Reordered = 2,3,4,5,5,7,9
Median = 5
Example: Even Number of Elements
Data Set = 2,5,9,3,4
Reordered = 2,3,4,5,9
Median = (4+5)/2 = 4/5
Mode: The "Mode" for a data set is the element that occurs the most often. It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set. A data set with two modes is called bimodal. A data set with three modes is called trimodal.
Example: Single Mode
Data Set = 2,5,9,3,5,4,7
Mode = 5
Example: Bimodal
Data Set = 2,5,2,3,5,4,7
Modes = 2 and 5
Example: Trimodal
Data Set = 2, 5, 2, 7, 5, 4, 7
Modes = 2, 5, and 7
Range: The "Range" for a data set is the difference between the largest value and smallest value contained in the data set. First, reorder the data set from smallest to largest then subtract the first element from the last element.
Example:
Data Set = 2, 5, 9, 3, 5, 4, 7
Reordered = 2, 3, 4, 5, 5, 7, 9
Range = (9-2) = 7
