Jenny was at bat 250 times.
What is the percentage?The percentage refers to a number that is out of 100. When describing components of a whole in mathematics, percentages are employed similarly to fractions and decimals. When employing percentages, the idea is that there are 100 equal pieces that make up the whole. In addition, the sign "%" is used to indicate that a number is a percentage. In stores, online, in commercials, and in the media, percentages are nearly always present. A crucial talent that may help you save time and money and raise your employability is the ability to comprehend what percentages represent.
Given jenny hit 32% of the time when she was at bat and also she had 80 hits. let's assume she had a total of x hits. so 32% of x will be equal to 80.

- The Blast Off Music Company makes CDs and DVDs. The company can make a total of 500 CDs and DVDS
each day. It costs $8 to make each CD and $10 to make each DVD. The company can spend $4800 for
production costs each day. How many individual CDs and DVDs can The Blast Off Music Company make in
one day?
Let C represent number of CDs and D represent number of DVDs.
We have been that The Blast Off Music Company can make a total of 500 CDs and DVDs each day. We can represent this information in an equation as:
[tex]C+D=500...(1)[/tex]
[tex]C=500-D...(1)[/tex]
We are also told that it costs $8 to make each CD, so cost of C, CDs would be [tex]8C[/tex].
It costs $10 to make each DVD, so cost of D, DVDs would be [tex]10D[/tex].
We have been given that the company can spend $4800 for production costs each day. This means that cost of C CDs and D DVDs will be equal to 4800. We can represent this information in an equation as:
[tex]8C+10D=4800...(2)[/tex]
Upon substituting equation (1) in equation (2), we will get:
[tex]8(500-D)+10D=4800[/tex]
[tex]4000-8D+10D=4800[/tex]
[tex]4000+2D=4800[/tex]
[tex]4000-4000+2D=4800-4000[/tex]
[tex]2D=800[/tex]
[tex]\frac{2D}{2}=\frac{800}{2}[/tex]
[tex]D=400[/tex]
Therefore, the company can make 400 DVDs in one day.
Upon substituting [tex]D=400[/tex] in equation (1), we will get:
[tex]C=500-D \Rightarrow 500-400=100[/tex]
Therefore, the company can make 100 CDs in one day.

Summit Plummet's big drop starts at point A(0, 120) and ends at point B (56, 0). What's the slope from point A to point B?
Answer:
15/-7
Step-by-step explanation:
slope is y(2) - y(1) / x(2) - x(1)
120-0/0-56
120/-56
simplified
The slope from point A to point B is found by dividing the rise by the run. With a rise of -120 and a run of 56, the slope is approximately -2.14, indicating a downward slope from A to B.
To find the slope from point A to point B, we can use the formula slope = rise/run. In this scenario, point A is at (0, 120) and point B is at (56, 0).
First, determine the rise, which is the change in the y-coordinates (vertical change). The rise is 0 - 120 = -120.
Next, determine the run, which is the change in the x-coordinates (horizontal change). The run is 56 - 0 = 56.
Now, we can calculate the slope: slope = rise/run = -120/56 = -2.14

Which of the following functions generates the sequence 0, 2, 4, 6, ...?
Answer:
F(n) = 2n – 2
Step-by-step explanation:
The sequence 0, 2, 4, 6
First, let us determine if the sequence is arithmetic progression (A.P) or geometric progression (G.P)
This is illustrated:
Let us calculate the common difference (d)
Common difference (d) = 2nd term – first term
Common difference (d) = 3rd term – 2nd term
=> 2 – 0 = 2
=> 4 – 2 = 2
The common difference (d) = 2.
Common ratio (r) = 2nd term /1st term
Common ratio (r) = 3rd term /2nd term
=> 2/0 = undefined
=> 4/2 = 2
There is no common ratio.
Since we have a common difference, therefore the sequence is arithmetic progression.
Now, let us obtain an expression for the sequence.
This can be obtained by using the arithmetic progression formula as shown below:
F(n) = a + (n – 1)d
a is the first term
n is the number of term
d is the common difference.
The sequence 0, 2, 4, 6
The first term (a) = 0
Common difference (d) = 2
F(n) = a + (n – 1)d
F(n) = 0 + (n – 1)2
F(n) = 2n – 2

Bernie drove from his house to his cousin's house in 6 hours at an average rate of 52 miles per hour he drove home at an average rate of 60 miles per hour how long did it take him to drive home
Answer:
7.5
Step-by-step explanation:
You have to divide the miles by the hours drived and then divide 60 per the miles per hour
Answer:
5.2 hours, or 5 hours 12 minutes
Step-by-step explanation:
The distance is the same in both cases. Since distance = rate (time),
time = distance / (rate).
Here, (6 hr)(52 mph) = (time)(60 mph, or
312 mi = (60 mph)(time), which gives us
(time) = (312 mi) / (60 mph) = 5.2 hours, or 5 hours 12 minutes
Look at this inequality.
−0.2x+1.2<1.1
To solve the inequality -0.2x+1.2<1.1, we subtract 1.2 from both sides and then divide by -0.2, which flips the inequality, resulting in x > 0.5.
To solve the inequality [tex]\frac{1.2}{-0.2x+1.2} < 1.1[/tex], we can follow a step-by-step process. First, we isolate the variable on one side. We'll subtract 1.2 from both sides of the inequality:
-0.2x+1.2-1.2 < 1.1-1.2
-0.2x < -0.1
Then we divide both sides by -0.2, remembering that dividing by a negative number will flip the inequality sign:
[tex]x > \frac{0.1}{0.2}[/tex]
x > 0.5
This means that for the inequality to hold true, x must be greater than 0.5. It's also important to note that by understanding the properties of inequalities and the operations performed on them, we can easily solve these mathematical statements.
A meteorologist reports that the temperature today will be colder than −1° Fahrenheit. The inequality is t < −1. The variable t represents the temperature. A number line going from negative 2 to positive 2. Which numbers are solutions of the inequality? Choose all that apply. –2 0 1 –10 –3 –1
For the inequality t < -1, the numbers that are solutions to this inequality are -2, -3, and -10, as they are all less than -1.\
The inequality in question is t < -1, which indicates that the temperature (t) is colder than -1 degrees Fahrenheit. On a number line from -2 to +2, the numbers that satisfy this inequality would be all the numbers that are less than -1. Therefore, the solutions to the inequality would be the numbers that are to the left of -1 on the number line.
-2
-3
-10
The numbers 0, 1, and -1 do not satisfy the inequality because they are not less than -1.

within a radius of 4.9 miles of a cell phone tower, 1483 people per square mile enjoy quality phone signals. what is the population of cell phones users within the towers converage area
Answer:
The population around the tower is 111,862 people.
Step-by-step explanation:
In order to solve this problem we first need to calculate the area surrounded by the tower, since it's a circle we can apply the following formula:
tower area = pi*r²
tower area = pi*(4.9)² = 75.4296 miles²
For every mile² there are 1483 people, therefore:
population = area*density
population = 75.4296*1483 = 111,862
The population around the tower is 111,862 people.

A piano teacher charges students $20.25 each month, plus $5.25 per hour for lessons.
Which expression and value represent the total the instructor will charge a student for x hours of lessons in a month and the amount the instructor would charge a student for 15 hours of lessons in a month?
$20.25 – x; $15
$20.25 + x; $25.50
$20.25 – $5.25x; $58.50
$20.25 + $5.25x; $99
Answer:
suppose the number of 2 hours lessons are x and 1 hour lessons are y; thus,
2x+y=25
50x+30y=690
to get the values of x and y we solve the quadratic equation given;
from the top equation:
y=25-2x.......i
substituting i in our second equation we get:
50x+30(25-2x)=690
50x+750-60x=690
-10x=-60
thus;
x=6
hence we conclude that the number of 2 hours classes are 6 hours
Step-by-step explanation:
The expression representing the total charge for x hours of piano lessons is $20.25 + $5.25x, and for 15 hours, the total charge would be $99.
Explanation:The correct expression to represent the total charge for a student who takes x hours of piano lessons in a month at $20.25 per month and $5.25 per hour is $20.25 + $5.25x. To calculate the amount the instructor would charge for 15 hours of lessons, we substitute x with 15:
