(2^4 – 5^3 – 7) + (−5^5 − 5^2 + 9 + 17)
Answer:
We can start by simplifying each parentheses separately and then adding the resulting expressions:
(2^4 – 5^3 – 7) + (−5^5 − 5^2 + 9 + 17)
= (16 - 125 - 7) + (-3125 - 25 + 9 + 17) (using the fact that 2^4 = 16 and 5^3 = 125)
= (-116) + (-3124) (combining like terms)
= -3240
Therefore, the answer is -3240. To express this number in standard form, we write it as:
-3.24 x 10^3
The negative sign indicates that the number is less than zero, and the 3.24 tells us the value of the number. The "x 10^3" part means that we need to multiply 3.24 by 10^3 (which is 1000) to get the actual value of the number:
-3.24 x 10^3 = -3.24 * 1000 = -3240
So, the answer in standard form is -3.24 x 10^3.

A. Create an equation to represent this word problem.
B. Solve the equation
Solving a linear equation we can see that he can afford to pay the monthly fee for 28 months
How long can he afford to pay the monthly fee?We know that there is an initial fee of $300 plus $7 per month, so the total cost after x months is:
C = 300 + 7*x
And we know that Julio has $500 set aside, then the equation that we need to solve is:
500 = 300 + 7x
500 - 300 = 7x
200 = 7x
200/7 = x = 28.5

What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum
Given that,
The sum of the digits of a certain two-digit number is 3.
Since it is a two digit number, there will be a tens place and a ones place.
Let x be the digit in tens place and y be the digit in ones place.
x + y = 3
The number can also be written as 10x + y, since x is in the tens place.
When the number is reversed, tens place changed to ones place and vice versa.
The reversed number is 10y + x.
Given that the value of the number is decreased by 27 when the digits is reversed.
Original number - 27 = Reversed number
10x + y - 27 = 10y + x
9x - 9y = 27
x - y = 3

elizabeth buys a package of 360 marbles. she gives away 216 of the marbles. what percent of the marbles did elizabeth give away?
Answer:
Elizabeth gave away 216 marbles out of a total of 360 marbles.
To find the percentage of marbles that Elizabeth gave away, we can use the formula:
percentage = (part/whole) x 100%
where "part" is the number of marbles Elizabeth gave away, and "whole" is the total number of marbles.
So, plugging in the values we have:
percentage = (216/360) x 100%
percentage = 0.6 x 100%
percentage = 60%
Therefore, Elizabeth gave away 60% of the marbles.
Subtract: (-4y^(2)+5d)-(-2y^(2)) Your answer should be in simplest terms. Enter the correct answer.
Subtracting -2y² from -4y² + 5d will give us -2y² + 5d.
A polynomial is a mathematical expression consisting of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, and multiplication.
To subtract the two polynomials, we first need to distribute the negative sign to the second polynomial.
So, (-4y² + 5d) - (-2y²) becomes -4y² + 5d + 2y².
Now, combine the like terms, which are the terms that contain y²:
-4y² + 5d + 2y² = (-4 + 2)y² + 5d
So, our final answer is:
-2y² + 5d.
Since our answer is in simplest terms, the final answer is -2y² + 5d.

What is the total surface area of the square
pyramid in square inches?
11 in
7 in
11.5 in
Answer:
To find the total surface area of a square pyramid, we need to find the sum of the areas of its base and its four triangular faces.
In this case, the base is a square with side length 11.5 inches. Therefore, its area is:
Area of base = 11.5^2 = 132.25 square inches
Each triangular face has a base length equal to the side length of the square base, which is 11.5 inches. To find the height of each triangular face, we can use the Pythagorean theorem. Since the pyramid is a square pyramid, the height of each triangular face is also the slant height of the pyramid.
The slant height of the pyramid can be found using the Pythagorean theorem:
a^2 + b^2 = c^2
where a = b = 11.5/2 = 5.75 (half the length of a diagonal of the square base) and c is the slant height. Solving for c, we get:
c = sqrt(a^2 + b^2) = sqrt(2*(5.75)^2) = 8.121 inches (rounded to 3 decimal places)
The area of each triangular face can be found using the formula:
Area of triangle = (1/2) * base * height
where the base is 11.5 inches and the height is 8.121 inches.
Area of each triangular face = (1/2) * 11.5 * 8.121 = 46.876 square inches (rounded to 3 decimal places)
So, the total surface area of the square pyramid is:
Total surface area = Area of base + 4 * Area of each triangular face
Total surface area = 132.25 + 4 * 46.876 = 330.124 square inches (rounded to 3 decimal places)
Therefore, the total surface area of the square pyramid is approximately 330.124 square inches.
Find the angle between \( \mathbf{u}=\langle-4,-1\rangle \) and \( \mathbf{v}=\langle-5,-2\rangle \) to the nearest tenth of a degree The angle between \( \mathbf{u} \) and \( \mathbf{v} \) is (Round
The angle between \( \mathbf{u}=\langle-4,-1\rangle \) and \( \mathbf{v}=\langle-5,-2\rangle \) is approximately 12.5 degrees. To the nearest tenth of a degree, we can round this to 12.5 degrees.
To find the angle between two vectors \( \mathbf{u} \) and \( \mathbf{v} \), we can use the formula:
\[ \cos \theta = \frac{\mathbf{u} \cdot \mathbf{v}}{\| \mathbf{u} \| \| \mathbf{v} \|} \]
where \( \theta \) is the angle between the vectors, \( \mathbf{u} \cdot \mathbf{v} \) is the dot product of the vectors, and \( \| \mathbf{u} \| \) and \( \| \mathbf{v} \| \) are the magnitudes of the vectors.
First, we need to find the dot product of \( \mathbf{u} \) and \( \mathbf{v} \):
\[ \mathbf{u} \cdot \mathbf{v} = (-4)(-5) + (-1)(-2) = 20 + 2 = 22 \]
Next, we need to find the magnitudes of \( \mathbf{u} \) and \( \mathbf{v} \):
\[ \| \mathbf{u} \| = \sqrt{(-4)^2 + (-1)^2} = \sqrt{16 + 1} = \sqrt{17} \]
\[ \| \mathbf{v} \| = \sqrt{(-5)^2 + (-2)^2} = \sqrt{25 + 4} = \sqrt{29} \]
Now we can plug these values into the formula and solve for \( \theta \):
\[ \cos \theta = \frac{22}{\sqrt{17} \sqrt{29}} \]
\[ \theta = \cos^{-1} \left( \frac{22}{\sqrt{17} \sqrt{29}} \right) \]
Using a calculator, we find that \( \theta \approx 12.5 \) degrees.
Therefore, the angle between \( \mathbf{u}=\langle-4,-1\rangle \) and \( \mathbf{v}=\langle-5,-2\rangle \) is approximately 12.5 degrees. To the nearest tenth of a degree, we can round this to 12.5 degrees.

a) Find the monthly payment needed to repay a $40,000 loan over 20 years, given that, as usual, the first repayment is made at the end of the first month, and the last at the end of the 240th. The interest rate is 0.5% per month.
b) Another $40,000 loan is repaid monthly, also over 20 years in a similar fashion. The monthly payment is $544.53. Find the monthly interest rate.
a) The monthly interest rate for the $40,000 loan repaid monthly over 20 years with a monthly payment of $544.53 is 0.00153. b) The monthly interest rate for the $40,000 loan repaid monthly over 20 years with a monthly payment of $544.53 comes out as 0.00153 percent
To find the monthly payment needed to repay a $40,000 loan over 20 years with a 0.5% interest rate per month, we can use the following formula: Monthly payment = (Loan amount * Monthly interest rate) / (1 - (1 + Monthly interest rate)^-Number of payments)
Plugging in the given values: Monthly payment = ($40,000 * 0.005) / (1 - (1 + 0.005)^-240) Monthly payment = $200 / (1 - 0.334) Monthly payment = $200 / 0.666, Monthly payment = $300.30
Therefore, the monthly payment needed to repay the $40,000 loan over 20 years with a 0.5% interest rate per month is $300.30.To find the monthly interest rate for a $40,000 loan repaid monthly over 20 years with a monthly payment of $544.53, we can use the same formula and rearrange it to solve for the monthly interest rate:
Monthly interest rate = (Monthly payment * (1 - (1 + Monthly interest rate)^-Number of payments)) / Loan amount. Plugging in the given values:
0.005 = ($544.53 * (1 - (1 + 0.005)^-240)) / $40,000
0.005 * $40,000 = $544.53 * (1 - (1 + 0.005)^-240)
$200 = $544.53 * (1 - (1 + 0.005)^-240)
$200 / $544.53 = 1 - (1 + 0.005)^-240
0.367 = 1 - (1 + 0.005)^-240
(1 + 0.005)^-240 = 0.633
1 + 0.005 = 0.633^-240
0.005 = 0.633^-240 - 1
0.005 = -0.367
Monthly interest rate = -0.367 / -240
Monthly interest rate = 0.00153

The product of 4/6-2a x 3-a/2 is equal to 2a-1. To calculate this, the fractions must first be simplified. 4/6 can be simplified to 2/3, and a/2 can be simplified to a/2. Next, the two terms should be multiplied together, resulting in 2a-1.
The product of 4/6-2a x 3-a/2 can be found by expanding the terms and then solving the equation. First, the fractions must be simplified. 4/6 can be simplified to 2/3, and a/2 can be simplified to a/2. Once the fractions are simplified, the two terms should be multiplied together, resulting in 2a-1. Now that the two terms have been multiplied, the equation can be expanded by using the Distributive Property. The equation should be written as (2/3-2a) x (3-a/2). This can be simplified by distributing the 2/3 and 3 across the parentheses. This results in (2-6a+2a^2) x (3-1/2a). Finally, the equation should be simplified by combining like terms. This results in 2-6a+2a^2+3-1/2a, which simplifies to 2a-1. Therefore, the product of 4/6-2a x 3-a/2 is equal to 2a-1.

in online music retailer generated an internal report about how many songs in each genre vere sold last year. Online music sales What is the measure of the central angle in the "Punk" section?
The measure of the central angle in the "Punk" section is 72 degrees.
Determine the central angleThe measure of the central angle in the "Punk" section can be determined by calculating the percentage of punk songs sold in relation to the total number of songs sold, and then converting that percentage to degrees.
To calculate the percentage of punk songs sold, divide the number of punk songs sold by the total number of songs sold, and multiply by 100.
For example, if 200 punk songs were sold and the total number of songs sold was 1000, the percentage of punk songs sold would be:
200/1000 * 100 = 20%
To convert this percentage to degrees, multiply the percentage by 360 (the total number of degrees in a circle).
20% * 360 = 72 degrees
Therefore, the measure of the central angle in the "Punk" section is 72 degrees.

Find the surface area of each figure. Round your answers to the nearest tenth, if necessary.
The total surface area of the given figures is:
1) 376 sq. feet
2)92sq. feet
What is meant by surface area?
The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. A solid object's surface area is a measurement of the overall space that the object's surface takes up. Every geometric shape has a different surface area formula, but the goal of all of them is to determine the total area occupied by all of the objects' faces.
1) This figure is a cuboid.
It has six faces and the opposite faces are of equal dimensions.
The surface area of a cuboid is the sum of the areas of each face.
Length l = 10 ft
Width w = 6 ft
Height h = 8 ft
Surface area = 2lw+2lh+2hw = 2 ( lw+ lh+ hw)
= 2 ( 10*6 + 10*8 + 8*6) = 376 sq. feet
2) This figure has 2 similar right triangle faces.
Sum of area of both triangles = 2 * 1/2 * base * height = 3 * 4 = 12 sq. feet
There are two rectangular faces.
Area of front rectangular face = 10 * 5 = 50 sq. feet
Area of base rectangular face = 10*3 = 30 sq. feet
Total surface area = 12 + 50 + 30 = 92sq. feet
Therefore the total surface area of the given figures is:
1) 376 sq. feet
2)92sq. feet

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
(a) To compute the probability of randomly selecting a diamond or heart from a standard deck of 52 cards, we need to count the number of diamond cards and heart cards in the deck. There are 13 diamond cards and 13 heart cards, so the total number of cards that are either diamonds or hearts is 13 + 13 = 26. Therefore, the probability of randomly selecting a diamond or heart is:
P(diamond or heart) = number of diamond cards + number of heart cards / total number of cards
P(diamond or heart) = 26/52
P(diamond or heart) = 1/2
P(diamond or heart) = 0.5
(b) To compute the probability of randomly selecting a diamond or heart or spade from a standard deck of 52 cards, we need to count the number of cards that belong to any of these three suits. There are 13 diamond cards, 13 heart cards, and 13 spade cards in the deck, so the total number of cards that are either diamonds, hearts, or spades is 13 + 13 + 13 = 39. Therefore, the probability of randomly selecting a diamond or heart or spade is:
P(diamond or heart or spade) = number of diamond cards + number of heart cards + number of spade cards / total number of cards
P(diamond or heart or spade) = 39/52
P(diamond or heart or spade) = 3/4
P(diamond or heart or spade) = 0.75
(c) To compute the probability of randomly selecting a seven or a heart from a standard deck of 52 cards, we need to count the number of seven cards and the number of heart cards in the deck. There are 4 seven cards and 13 heart cards, but we need to be careful not to double-count the seven of hearts. Therefore, the total number of cards that are either sevens or hearts is 4 + 12 = 16. Therefore, the probability of randomly selecting a seven or a heart is:
P(seven or heart) = number of seven cards + number of heart cards - number of seven of hearts / total number of cards
P(seven or heart) = 16/52
P(seven or heart) = 4/13
P(seven or heart) ≈ 0.308
Hence, The probabilities are:
(a) P(diamond or heart) = 0.5
(b) P(diamond or heart or spade) = 0.75
(c) P(seven or heart) ≈ 0.308.
