After changing its format, a radio station lost 34% of its listeners. If there were an estimated 83,000 listeners orginally, how many listeners does the radio station have now?
Final answer:
The radio station has 54,780 listeners now.
Explanation:
To find the number of listeners the radio station has now, we need to calculate the number of listeners it lost after changing its format. If the station lost 34% of its listeners, we can calculate the number of lost listeners by multiplying the original number of listeners by 0.34 (34%).
Lost Listeners = 83,000 * 0.34 = 28,220 listeners
To find the number of listeners the radio station has now, we subtract the lost listeners from the original number of listeners.
Number of Listeners Now = 83,000 - 28,220 = 54,780 listeners
A company makes traffic signs.One of their signs can be modeled by an equilateral triangle with a perimeter of 144 inches. The company makes a similar sign with perimeter that is 1.25 times the one shown. What is the height in inches of the larger sign?
Answer:
The perimeter of the larger sign : 144*1,25= 180 inches
Side of the triangle= 180/3= 60 inches
square of the height= 60^(2) - 30^(2)= 2700 ( Pythagoras' theorem)
height= square root ( 2700)= 51,96
Step-by-step explanation:
To find the height of the larger sign, determine the scale factor between the two signs and use the formula for the height of an equilateral triangle.
Explanation:To find the height of the larger sign, we need to determine the scale factor between the two signs. The perimeter of the original sign is 144 inches, and the new sign has a perimeter that is 1.25 times the original. This means the perimeter of the new sign is 144 x 1.25 = 180 inches.
Since the original sign is an equilateral triangle, each side has a length of 144/3 = 48 inches. The larger sign will have sides that are 180/3 = 60 inches in length.
Since the larger sign is also an equilateral triangle, we can use the formula h = (√3/2) x s, where h is the height and s is the length of a side. Therefore, the height of the larger sign is h = (√3/2) x 60 = 51.96 inches (rounded to two decimal places).

Please explain how you got your answer.
A. y > or = 3x +4
B. y < or = 3x + 4
C. y < or = 3x - 4
D. y > or = 3x - 4
Answer:
D. y > or = 3x - 4
Step-by-step explanation:
Looking at the graph, we know the y intercept, or where the graph crosses the y axis, is -4.
We can find the slope of the line from 2 points (0,-4) and (2,2)
The slope is given by
m = (y2-y1)/(x2-x1)
= (2--4)/(2-0)
= (2+4)/(2-0)
=6/2
=3
Using the slope intercept form for the line, y=mx+b
y = 3x+-4
y = 3x-4
The graph is shaded above the line so y is greater than the line, and the line is solid so y is also equal to the line
y ≥3x-4

the perimeter is at least 18 feet. Write and solve inequality that represents x
The inequality that represents x is [tex]$x \geq 6$[/tex]. This means that the total length of all the sides of the shape must be at least 6 feet.
Let's say the total length of all the sides of the shape is represented by the variable x. We are given that the perimeter is at least 18 feet. This can be written as an inequality: [tex]$x \geq 18$[/tex]
Since the sides of the triangle measure 3 feet, 5 feet and x-2 feet, we can express the perimeter inequality in terms of x as: [tex]$x+ 3 + 5 +x-2 \geq 18$[/tex]
Simplifying the left side of the inequality, we get: [tex]$2x + 6 \geq 18$[/tex]
Subtracting 6 from both sides, we obtain: [tex]$2x \geq 12$[/tex]
Dividing both sides by 2, we get: [tex]x \geq 6$.[/tex]

Write a number in which the value of the 3 is 10 times the value of the digit 3 in 156.32
Answer:
1563.2
Step-by-step explanation:
If you just multiply 0.3 by 10 you will get 3
Now all you need to do is write 3 or have a number which has unit place value of 3
Answer: The number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3
Step-by-step explanation:
The given number = 156.32
The place value of 3 in 156.32 is 3 tenth [since it the left most number after the decimal].
3 tenth can be written as [tex]\frac{3}{10}[/tex]
The number 10 times [tex]\frac{3}{10}[/tex]= [tex]10\times\frac{3}{10}[/tex]
Therefore, The number 10 times [tex]\frac{3}{10}[/tex]=3
Hence, the number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3
What’s 22.5 as a fraction in simplest form
Answer:
22.5% = 9/40 as a fraction
Step by Step Solution
To convert 22.5 percent to a fraction follow these steps:
Step 1: Write down the percent divided by 100 like this:
22.5% = 22.5/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
22.5/100 = (22.5 x 10)/(100 x 10) = 225/1000.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25. So,
(225÷25)/(1000÷25) = 9/40 when reduced to the simplest form.
Step-by-step explanation:
Answer:
9/4, or 2 1/4 is your answer
Step-by-step explanation:
Note that 22 is a whole number, and that 5 is a decimal.
Change the decimal into a fraction. To do so, move the decimal point to the right two place values and set the number over 100
22.5 = 225/100
Simplify.
(225/100)/(25/25) = 9/4
9/4, or 2 1/4 is your answer

2y = 2*(1/2) x
2y = x
Substitute this value into equation 2.
2y + 4y = 18 Combine like terms on the left
6y = 18 Divide both sides by 6
6y/6 = 18/6 Do the division
y = 3
To solve for x just use the top equation
y = 1/2x
3 = 1/2x Multiply by 2
3*2 = x
x = 6

You are making a poster to support your friend for homecoming. Your original photo is 3 inches by 5 inches. You want the photo on the poster to be 2 1/2 feet by 4 1/6 feet. What is the scale factor of this dilation?
Answer:
9
Step-by-step explanation:
We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.
First of all we will convert dimensions of poster from feet to inches.
3ft = 3x12 in = 36ft
4 1/2 ft = 4.5x 12in = 54in
Now let us compare sides of our original photo with corresponding sides of poster.
frac{36}{4} = 9
Now let us compare the second pair of corresponding sides.
\frac{54}{6} =9
We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.
To find the scale factor for enlarging a photo from 3 inches by 5 inches to 2 1/2 feet by 4 1/6 feet, first convert feet to inches and then compare the dimensions of both photos. The scale factor is 10, as both width and height are enlarged by a factor of 10.
Explanation:You are making a poster and need to determine the scale factor for resizing a photo from 3 inches by 5 inches to 2 1/2 feet by 4 1/6 feet. To find the scale factor, you compare the dimensions of the enlarged photo to the original photo.
First, convert the measurements of the larger photo from feet to inches, since the original photo is in inches (1 foot = 12 inches):
2 1/2 feet = 2.5 * 12 inches = 30 inches
4 1/6 feet = (4 + 1/6) * 12 inches = (4 * 12) + (1/6 * 12) inches = 48 + 2 inches = 50 inches.
Next, calculate the scale factor for each dimension separately and check that they are consistent:
Scale factor for width = 30 inches / 3 inches = 10
Scale factor for height = 50 inches / 5 inches = 10
Since both width and height have the same scale factor of 10, the overall scale factor for the dilation is 10.
Which system of inequalities is shown in the graph?
The system of the inequalities is y ≥ 2x - 2, y ≥ x - 3x. Option B
How to determine the inequalitiesTo determine a system of inequalities graphically, plot each inequality on the same coordinate plane.
Represent each inequality as a boundary line (dashed or solid, depending on the inequality sign) and shade the region that satisfies the inequality. The solution area is the overlapping shaded region where all inequalities intersect.
The points within this shared region satisfy all the given inequalities simultaneously. If there is no intersection or common shaded area, the system has no solution that satisfies all the inequalities simultaneously.
So, we have that;
y ≥ 2x - 2
y ≥ x - 3x

The price of a Barry bonds baseball card in 2001 was $50. It is now being sold for $30. Find the percent decrease in the cost of the card
Final answer:
The percent decrease in the cost of the Barry Bonds baseball card is 40%.
Explanation:
To calculate the percent decrease in the cost of the card, we can use the formula:
Percent decrease = ((original value - new value) / original value) * 100
In this case, the original value of the card was $50 and the new value is $30. Plugging in these values into the formula:
Percent decrease = ((50 - 30) / 50) * 100 = (20 / 50) * 100 = 0.4 * 100 = 40%
Therefore, the percent decrease in the cost of the card is 40%.

A group of 40 people went to the theme park. While there, each person bought popcorn. Regular bags of popcorn sold for $6 per bag. Super size sold for $8 per bag
Each person in the group could have either bought a regular bag of popcorn for $6 or a super size bag for $8. The total costs would be $240 and $320 respectively.
Explanation:In this scenario, we have a group of 40 people each buying popcorn at a theme park. The prices available were the regular bag for $6 each or the super size for $8 each. Depending on their choice, the total amount spent will vary. For example, if every person in the group purchased a regular bag, the total would be 40 * $6 = $240. And if everyone decided to get a super size bag, it would end up being 40 * $8 = $320

ou work at the Peacock Blue store 40 hours/week over five days at a rate of $10.25/hour. Deductions are FICA (7.65%), federal withholding (15%), and state withholding (10%). Your expenses are transportation at $5.25/day, lunch at $3.85/day, and black slacks required for work at $19.95. How much is your discretionary income for one week?
Answer:
$210.69
Step-by-step explanation:
Firstly, just calculate how much money you earn:
40 * 10.25 = $410
Your transportation expenses = 5.25 * 5 = $26.25
Your lunch expenses = 3.85 * 5 = $19.25
Expenses for black slacks = $19.95
FICA = 7.65/100 * 410 (money you earned) = $31.365
Federal withholding = 15/100 * 410 = $61.5
State withholding = 10/100 * 410 = $41
Your discretionary income = 410 - (26.25 + 19.25 + 19.95 + 31.365 + 61.5 + 41) = $210.69

Please give brainliest!!!☺
Answer:
15
Step-by-step explanation:
Danny buys 4 pizzas and some pretzels for his baseball team.
The cost of each pizza is $8.99
Total cost of 4 pizza = 4 × 8.99
= $35.96
Let buy p numbers of pretzels whose cost $0.99 each.
Total cost for p pretzels = 0.99p
Total spend by Danny on pizzas and pretzels = $50.81
35.96 + 0.99p = 50.81
0.99p = 50.81 - 35.96
0.99p = 14.85
p = 15
Hence, Danny bought 15 pretzels for baseball team.
