Answers

Answer:
x = 5.07142
Step-by-step explanation:
To solve the equation ...
sin(25°) = x/12
multiply by the denominator of the x term.
12·sin(25°) = 12(x/12)
x = 12·sin(25°)
x ≈ 5.07142

A subway ride for a student costs $1.25. A monthly pass costs $35.
a. Write an inequality that represents the number of times you must ride the
subway for the monthly pass to be a better deal.
b. You ride the subway about 45 times per month. Should you buy the monthly
pass? Explain.
Answers
A: 29 times
B: Yes
Explanations:
A: You do 35/1.25 and get 28, but thats not a better deal that's the same, so you go up one and make it 29.
B: Yes, 45(1.25) is 56.25 which is well over 35
Answer:
a. x(1.25) > $35
b. 45(1.25) = 56.25. Yes you should buy the monthly pass opposed to paying $1.25 each time you ride the subway.
Step-by-step explanation:
a. x = (number of subway rides) 1.25 = (cost per subway ride)
> = the cost of paying individual subway rides surpasses the cost of the monthly pass therefore making it a better deal.
b. If you ride the subway 45 times, 45 x 1.25 = 56.25 which is $21.25 more than the $35 monthly subway pass, which makes the monthly pass more practical.

Someone help plz I need some help good at finding slope people? Anyone
Answers
since the slope is decreasing, it is negative.
Answer:
So the slope is -5/2.
Step-by-step explanation:
You want to look at the line to find the slope of it. For slope you want to find rise/run. This is the same as: change in y/change in x. awe have 2 points (the blue dots) to find slope. With this, let's find the change in y and the change in x. For those 2 dots, the change in y is down 5, which means -5 (if it was up 5 it would be 5)For change in x, it is to the right 2, which means 2 (if it was 2 to the left then it would be -2). Therefore, the slope would be change in y/change in x which is -5/2 (the 3rd option)Find the length of side x simplest radical form with a rational denominator

The length of x in the simplest radical form with a rational denominator will be:
[tex]x=\frac{5\sqrt{3}}{2}[/tex]Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so
[tex]cos\:60^{\circ }\:=\:\frac{x}{5}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{x}{5}[/tex]
switch sides
[tex]\frac{x}{5}=\frac{\sqrt{3}}{2}[/tex]
Multiply both sides by 5
[tex]\frac{5x}{5}=\frac{5\sqrt{3}}{2}[/tex]
Simplify
[tex]x=\frac{5\sqrt{3}}{2}[/tex]
Therefore, the length of x in the simplest radical form with a rational denominator will be:

Answer:
72
Step-by-step explanation:
(9+9+7^2)-4+9
(9+9+49)-4+9
67-4+9=72
I believe this is correct.
Answer:
(9+9+7^2)-4+9= 72
Step-by-step explanation:
Using PEMDAS, we can solve this problem easily. First, look for parentheses. Inside of the parentheses is an exponent, 7^2. This equals 49. Continuing to solve inside the parentheses, we get 9+9+49= 67. Now, we add and subtract from left to right. Our new equation looks like 67-4+9=?. 67 minus 4 is 63, and 63 plus 9 is 72. Thus, the answer to this equation is 72.

Step-by-step explanation:

Step-by-step explanation:
.45 x 3 = 1.35

$10 - 4.85 = 5.15
Juelle had $25,000 to invest. She invested part of that amount at 3% interest and part at 5% interest for one year. The amount of interest she earned for both investments was $1100. How much was invested at each rate?
Answers
Answer:
The first amount invested at 3%= x = $7500
The second amount Invested at 5% = y = $17500
Step-by-step explanation:
Juelle had $25,000 to invest.
She invested part of that amount at 3% interest and part at 5% interest for one year.
The amount of interest she earned for both investments was $1100.
The formula for Simple Interest =
Principal × Rate × Time
Let us represent
The first amount invested at 3%= x
The second amount Invested at 5% = y
x + y= $25,000....... Equation 1
x = 25,000 - y
3% × x + 5% × y = $1100...... Equation 2
0.03x + 0.05y = 1100...... Equation 2
We substitute 25000 - y for x in Equation 2
0.03x + 0.05y = 1100
0.03(25000 - y) + 0.05y = 1100
750 - 0.03y + 0.05y = 1100
Collect like terms
- 0.03y + 0.05y = 1100 - 750
0.02y = 350
y = 350/0.02
y = 17500
Solving for x
x = 25,000 - y
x = 25000 - 17500
x = 7500
Therefore:
The first amount invested at 3%= x = $7500
The second amount Invested at 5% = y = $17500

Median is 8 I THINK but if someone else answers and says only answer then they are right
Mean is 6
Answer:
mean= 6
median= 5.5
mode= 4
Step-by-step explanation:
mean is all the numbers added up then divided the total amount of numers up then divide. 2+3+4+4+4+7+7+8+9+12=60/10=6
median is the numbers lowest to highest then the middle number
2,3,4,4,4,7,7,8,9,12 the median is 5.5 because that is the middle between 4 and 7
mode is the most frequent value and that is 4 because 4 shows us 3 time and 7 showsup 2

Answers
Answer:
7
Step-by-step explanation:
The number of players that play all three positions will be 7 for the given data.
What are permutation and combination?When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.
The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.
As per the given,
Total players = 22
5 play defense only 4 play midfield only and 6 play attack only
5 + 4 + 6 = 15
22 - 15 = 7 play all positions.
Hence "The number of players that play all three positions will be 7 for the given data".
