Answer:
The percent increase of the population of chipmunks was 29%
Step-by-step explanation:
we know that
The population of 300,000 chipmunks represent the 100%
The increase of population is equal to
(387,000-300,000)=87,000 chipmunks
Using proportion find the percent increase
Let
x-----> the percent increase
300,000/100%=87,000/x
x=100*87,000/300,000
x=29%
If 90 students were surveyed and 50 said they would buy a wristband, how many wristbands should Monty order for the school of 1800 students?
He should buy 1000 wristbands.
Since 50/90 students said they would buy a wristband, we can set up this proportion.
[tex]\frac{50}{90}[/tex] [tex]\frac{x}{1800}[/tex]
multiply 50 * 1800 divided by 90 = 1000
2-(-8c)+24-7c simplified
Answer:
26+c
Step-by-step explanation:
The given expression 2-(-8c)+24-7c simplifies to 26 + c by removing the parenthesis, changing the sign of -8c to +8c, combining like terms, and adding the constants.
The equation 2-(-8c)+24-7c simplifies by applying the distributive property and combining like terms. We first remove the parentheses and change the sign of the term inside, which is -8c, to a positive. Then we combine the like terms, -8c and -7c. The equation simplifies to:
2 + 8c + 24 - 7c = 2 + 24 + (8c - 7c) = 26 + c
So, the given expression simplifies to 26 + c.

Liz earns a salary of $2,500 per month, plus a commission of 6% of her sales. She wants to earn at least $2,700 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal.
Final answer:
To find the amounts of sales that will meet Liz's goal, we can set up an inequality using her salary and commission. Liz needs to earn at least $2,700 this month, and with her salary and commission, we can create the inequality $2,500 + 0.06x ≥ $2,700. Solving this inequality gives us x ≥ $3,333.33. Therefore, the amounts of sales that will meet Liz's goal are any values of x that are greater than or equal to $3,333.33.
Explanation:
To find the amounts of sales that will meet Liz's goal of earning at least $2,700 this month, we can set up an inequality. Let's represent the amount of sales as 'x'.
Liz's salary is $2,500 per month, and her commission is 6% of her sales. So her total earnings for the month can be calculated as:
Total Earnings = Salary + Commission
Total Earnings = $2,500 + 0.06x (since the commission is 6% of sales)
We want Liz to earn at least $2,700, so we can set up the following inequality:
$2,500 + 0.06x ≥ $2,700
To solve this inequality, we can subtract $2,500 from both sides:
0.06x ≥ $2,700 - $2,500
0.06x ≥ $200
Finally, we divide both sides by 0.06 to isolate 'x', the amount of sales:
x ≥ $200 ÷ 0.06
x ≥ $3,333.33
Therefore, the amounts of sales that will meet Liz's goal are any values of 'x' that are greater than or equal to $3,333.33.

What does |a|=|b| mean?
Answer:
a = ±b
Step-by-step explanation:
The vertical bars are the symbol for "absolute value", so the equation is saying, "the absolute value of 'a' is equal to the absolute value of 'b'." The absolute value is the magnitude of a number, so, for example, |-3| = 3.
If the magnitudes of two numbers are the same, they may be the same value, or they may differ in sign.
Answer:
See below.
Step-by-step explanation:
The 2 vertical lines about the letters mean ' the absolute value of' . That is if a or b have negative values then the absolute value will be the positive . For example if a = -4 then |a| = 4. The absolute value is always positive.
Therefore, for example, if a is 2 and b = -2 then |a| will be equal to |b|, because they both have a value of 2.

In the early 1900's the majority of the Americans rejected the Marxist ideology, and they saw it as usurpation of their country and its foundations. The majority of the Americans favored the capitalism, and they saw their country as the country of opportunities where everyone can achieve everything if the person is smart enough and works hard enough. The Marxism suggested the total opposite of it, that everyone should be equal, have the same earnings, there's no prosper on a career level, so for the Americans was not attractive, and we can comfortably say that they made the right choice considering what happened in the countries that adopted this ideology.

The most appropriate domain for calculating the cost to download songs after paying a membership fee is whole numbers greater than or equal to one, as you cannot download fractional or negative numbers of songs.
Explanation:The most appropriate domain for calculating the cost to download songs, given the information that an online company charges a $5 membership fee and then $0.99 for each song, would be option 2, which is whole numbers greater than or equal to one. The domain is referring to the number of songs you can download after the initial membership fee. Since you cannot download a fraction of a song or a negative number of songs, whole numbers make the most sense in this context. The cost for downloading songs would be the membership fee plus the cost per song times the number of songs downloaded, which is a linear relationship.
How will you write 7^5 as a multiplication expression?
A.
7 * 5
B.
7*7*777
C.
5 x 5 x 5 x 5 x 5 x 5 x 5
Answer:
The answer is 7*7*7*7*7
Step-by-step explanation:
The correct way to write 7^5 as a multiplication expression is by writing it as 7 multiplied by itself 5 times, which is 7 x 7 x 7 x 7 x 7.
The question asks how to write 7^5 as a multiplication expression. To correctly express 7^5, we represent it as 7 being multiplied by itself 5 times. So, the correct way to write 7^5 as a multiplication expression is 7 \u00d7 7 \u00d7 7 \u00d7 7 \u00d7 7. This clearly demonstrates the concept of an exponent, where the base (7) is multiplied by itself a certain number of times (5 times in this case), which is fundamentally different from just multiplying 7 by 5.

The true statement regarding the shape are:
The three-dimensional solid is a hexagonal pyramid.The solid can be created by stacking dilated hexagons vertically.Point D is the apex of the pyramid.Base: The bottom surface of a pyramid is a polygonal shape, such as a square, rectangle, triangle, or any other polygon. The base is typically larger in area compared to the other faces.
Faces: Pyramids have triangular faces that slope inward from the edges of the base to a single point at the apex. The number of faces depends on the number of sides of the base polygon.
Vertices: A pyramid has several vertices where the edges of the base meet the triangular faces, and one vertex where all the triangular faces converge at the apex.
Edges: The edges of a pyramid are the lines where the faces intersect. For example, a square pyramid has 8 edges (4 from the base and 4 connecting the base to the apex).

4708.06 rounded to nearest thousand
Answer
5,000
Explanation
1. Examine the number next to the thousands value (hundreds place)
2. Should that number be greater than 5, round the thousands value up one.
To round 4708.06 to the nearest thousand, we look at the hundreds place value which is '7'. Since it's higher than 5, we round up the thousands of places and the number becomes 5000.
Explanation:The process of rounding involves deciding which multiple of a certain number is closest to the number you're trying to round. If to round the number 4708.06 to the nearest thousand, we look at the hundreds place. In our case, it's '7', a digit that is 5 or higher.
Thus, we increase the digit at the thousands place by '1' and change all the subsequent digits to '0'. Therefore, 4708.06 rounds to 5000 when rounded to the nearest thousand.

If you rotate the triangle so that the 6 is on the bottom, the two sides are both 6.2.
Because the two sides are equal the two angles at the bottom would also be equal. One is given as 61 degrees, so the other bottom angle is also 61 degrees.
The three inside angles of a triangle need to equal 180, so X would equal 180 minus the two bottom angles.
X = 180 - 61 - 61 = 58 degrees.
