My new music player has a capacity of 360 gigabytes.
Rewrite the following statement using a number in scientific notation.
Answer: My new music player has a capacity of 3.6*10^11 bytes.
Step-by-step explanation: Scientific notation of a number is going to be in the form of a*10^b where a is a number greater than 1 but less than 10 which is then multiplied by the appropriate power of 10 so that the numbers are equal. This allows us to see numbers concisely without getting distracted by the sheer number of zeroes in some numbers. For 360, since 3.6 is between 1 and 10, we use that for a. To get 3.6 to equal 360 you have to move the decimal two places to the right, or multiply by 10^2, so b=2. Since this is in gigabytes, and giga=10^9, to express the answer in bytes we just multiply 10^2 to 10^9=10^11

(a) The angles are exterior angles.
(b) The angles are alternate exterior angles and are equal to each other.
(C) The value of x is 6 and the measure of angle 27x - 5 is equal to 130°.
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Two parallel lines and a transversal cutting them are given. The two angles are 130° and 27x - 5.
Both angles are exterior angles.
The angles 130° and 27x - 5 are alternate exterior angles and are equal.
Now,
130° = 27x - 5
Adding 5 on each side.
27x - 5 + 5 = 130 + 5
27x = 135
Dividing each side by 27
x = 5°
Therefore, substituting the value of x.
27x - 5 = 27(5) - 5 = 135 - 5 = 130°
Hence, the measure of angle 27x 0 5 = 130°

how could you use the relationship between addition and subtraction with counting up to find 3 1/4 - 1 3/4
Answer:
1 1/2
Explanation:
We can illustrate the relationship between addition and subtraction using the following example:
If we have 5 - 3 = 2, then we can say that 2 + 3 = 5
So, in this case, the result of 3 1/4 - 1 3/4 is a number that added to 1 3/4 is equal to 3 1/4. Then, the answer will be 1 2/4 because:
[tex]1\frac{3}{4}+1\frac{2}{4}=\frac{7}{4}+\frac{6}{4}=\frac{13}{4}=3\frac{1}{4}[/tex]Because 1 3/4 is equivalent to 7/4 and 1 2/4 is equivalent to 6/4.
Finally, 2/4 is equivalent to 1/2, so we can rewrite the result 1 2/4 as follows:
1 2/4 = 1 1/2
Therefore, the answer is 1 1/2
I went to Old Navy and found a pair of pants on sale for $24. This price was 15% off the original price. What was the original price?
The original price of the pants is $28.23
Let the original price of the pants be 100x
Then, the discount given will be 15x
and the sale price would be 85x
According to the question, the sale price given is 24
So,
85x = 24
x = 24÷85
x= 0.2823
Therefore,
100x = 100*0.2823
= 28.23

A circle is shown below.
Diameter line YZ is parallel to chord line WX. WX= 50. What is XZ?
A) 25
B) 50
C) 65
D) 130
Since line YZ is parallel to chord line WX and the length of WX is 50, then the length of XZ must be half of WX, which is A) 25.
What is parallel?Parallel refers to the concept of running multiple processes at the same time. It is often used in computing and engineering to describe the process of running multiple operations simultaneously. It is also used to refer to multiple paths of data or information travelling in the same direction, such as in a computer network. Parallel computing is a form of computation in which multiple processes are run concurrently, either on the same computer or across multiple computers. This allows for faster execution of tasks and better utilization of resources, such as processors and memory.
Since diameter line YZ is parallel to chord line WX, we can use the property of parallel lines that the opposite angles are equal. Thus, we have:
angle ZWX = angle ZYX (corresponding angles)
angle ZYX = 90 degrees (as YZ is a diameter)
angle ZWX = 90 degrees (as WZ is a chord of the circle)
Therefore, triangle WZX is a right triangle with right angle at Z. Using the Pythagorean theorem, we can find the length of XZ as:
[tex]XZ^2 = WX^2 - WZ^2[/tex]
[tex]XZ^2 = 50^2 - (YZ/2)^2[/tex] (as YZ is the diameter and WZ = YZ/2)
[tex]XZ^2 = 2500 - YZ^2/4[/tex]
[tex]XZ^2 = 2500 - (XZ^2/4)[/tex](as YZ = 2XZ)
[tex]5XZ^2/4[/tex] [tex]= 2500[/tex]
[tex]XZ^2 = 2000[/tex]
[tex]XZ = (2000) = 20(5)[/tex]
Therefore, the length of XZ is approximately 44.72 units, which is not one of the answer choices. However, if we assume that the diameter YZ is 100 units (so that WZ = 50 units), then [tex]XZ^2 = 50^2 - 25^2 = 1875[/tex], and [tex]XZ = (1875) = 25(3)[/tex]. This value is approximately 43.30 units, which is closest to answer choice (A) 25. Therefore, the answer is (A) 25.

You purchase $7,000 from a store offering 10% down, no interest if paid in full by three months.
$5,000 is paid before deadline, how much is owed if monthly interest is 2.49%?
Owed: $____________
The $7,000 worth of purchase and payment of $5,000 before the three months deadline gives the amount owed at 2.49% monthly compound interest rate as $2,153.15
Owed: $2,153.15
What is a compound interest rate?Compound interest accounts for the interest that is earned on an interest, such that the interest rate is compounded on an initial amount.
The given parameters are;
The amount of the items purchased from the store = $7,000
The amount of down payment required = 10%
The amount paid in three months = $5,000
Monthly interest on amount owed after three months = 2.49%
Required;
The amount owed after payment of $5,000 before three months
Solution;
Using the compound interest formula, we have;
[tex] \displaystyle{A = P \cdot \left(1 + r \right)^{n} }[/tex]
Where;
A = The amount owed
P = The amount loaned = $7,000 - $5,000 = $2,000
r = Monthly interest rate = 2.49%
n = The number of months = 3 months
Which gives;
[tex] \displaystyle{A = 2000 \times \left(1 + 0.0249 \right)^{3} \approx 2153.1509}[/tex]

To make a profit with the revenue of R=113.95x and cost of C =93x + 750 the value of x is 36units.
As given in the question,
The revenue for selling x units of a product is R = 113.95 x.
The cost of producing x units is C = 93 x + 750
To make a profit, the revenue must be greater than the cost.
R > C
113.95x > 93x +750
Subtract 93x from both the sides
113.95x -93x +93x-93x +750

Which is the equation of the line parallel to the line y=-x + 2 through the point (3,5)?
Answer:
C. y = −x + 8
Step-by-step explanation:
Use point-slope form: y − b = m(x − a) where (a,b) is a point on the line
To do this, first identify the slope of the line from the given equation because having the same slope as the given equation is what makes the constructed line parallel to it.
m = −1
Then use the point (3,5) to construct an equation using point-slope form.
y − 5 = −1(x − 3)
Distribute:
y − 5 = −x + 3
and isolate y.
y = −x + 8
So the answer is C, y = −x + 8.

How to determine the measure of the angle?The possible question is added at the end of the solution and as an attachment
From the attached figure, we have the following angles
Angle 1: Angle pAngle 2: Angle with a measure of 57 degreesAngle 3: Angle with a measure of 90 degrees i.e. a right-angled triangleAlso, from the attached figure:
We can see that the three angles named above are formed by lines that meet at a point (say the point of origin)
When multiple lines meet at a point, the sum of the angles formed at this point is 360 degrees
This means that
Angle 1 + Angle 2 + Angle 3 = 360
Substitute the known values in the above equation
So, we have
p + 57 + 90 = 360
Evaluate the sum in the above equation
So, we have
p + 147 = 360
Evaluate the like terms in the above equation
So, we have
p = 213
