In Mrs. Wilson's math class, the ratio of girls to total students is 5 to 8. If there are 24 total students, how many boys are in the class? (help please! i also need work for understanding this problem, thank you!)
Answer:
9 boys are in the class
Step-by-step explanation:
5 to 8
5 x 3 = 15 girls
24 - 15 = 9 boys
9 boys in the class
There are 9 boys in the class.
What is Ratio?
A ratio indicates how many times one number contain in another number.
Given that;
In Mrs. Wilson's math class,
The ratio of girls to total students is 5 to 8.
Total student in the class = 24
Now, Let number of girls = 5x
And, Total number of student = 8x
Since, Total student in the class = 24
Hence,
8x = 24
x = 24/8
x = 3
Thus, Number of girls = 5x = 5 × 3 = 15
So, Number of boys = total student - number of girls
= 24 - 15
= 9
Thus, There are 9 boys in the class.

Abe has 150 t-shirts to sell before the playoffs begin. The table shows the linear relationship between the number of t-shirts remaining, y, and the number of days he has been selling, X. T-shirt Sales Number of Number of Days T-shirts Remaining х
Which function can be used to find y, the number of t-shirts remaining after x days?
Answer:
Y= -12x + 150
Step-by-step explanation:
1. You do the change in y over the change in x to get the slope.
y1 - y2 / x1 - x2 and you get the slope of -12
2. Making a point-slope form equation
y-y1=m(x-x1)
y-138= -12(x-1)
3. Turning point-slope form equation to slope-intercept
y-138= -12(x-1)
distributive property
y-138=-12x+12
add 138 on both sides

Answer:
1) Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2) Let x be the number of miles.
Then, we have inequality: [tex]8x+2\leq 10[/tex]
Solve the inequality: [tex]8x+2\leq 10[/tex]
Subtract 2 from both the sides: [tex]8x+2-2\leq 10-2[/tex]
Simplify: [tex]8x\geq 8[/tex]
Divide by 8 both sides we get: [tex]x\leq 1[/tex]
as shown in figure 1.
3) From the context of the problem : we can say that Paul can travel 1 miles or less before reaching his limit of $10.

Describe the probability of rolling a number greater than 5 on a standard number cube.
Answer:
1:6
Step-by-step explanation:
there are 6 numbers on a standard dice. 1, 2, 3, 4, 5 are all less than or equal to 5. So, the only numver greater than 5 is 6. the probability 1/6
The probability of rolling a number greater than 5 on a standard number cube will be 1/6.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The probability of rolling a number greater than 5 on a standard number cube will be
The total number of the event will be
Total event = 6 {1, 2, 3, 4, 5, 6}
The favorable event will be
Favorable event = 1 {6}
Then the probability will be
P = 1/6

Step-by-step explanation:
A bookstore is deciding what price it should charge for a certain book. After research, the store finds that if the book's price is p dollars (where p <= 40), then the number of books sold per month is 120-3p. What price should the store charge to maximize its revenue?
The store charge that has to be charged should be 20$
How to solve for the chargeFirst we have to solve for revenue
Revenue = Price x quantity
= p * 120-3p
= 120p - 3p²
The maximum revenue is at the point where p = - b/2a
Hence we have
-120/2 *-3
= -120/-6
= $20
Hence the amount that has to be charged by the store should be $20
