75 % of the students are boys . There are 24 boys . What is the total number of Students
PLEASE HELLPPPPPO
Answer:
32 students
Step-by-step explanation:
24 divided by .75 is 32
Based on the information given, there'll be 32 students.
Let the total number of students be represented by x.
From the information, it was stated that 75% of the students are boys and that there are 24 boys. Therefore, the total number of students will be:
75% × x = 24
0.75x = 24
x = 24/0.75
x = 32
There are 32 students.

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola
y=2-x^2. What are the dimensions of such a rectangle with the greatest possible area?
width=?
height=?
Take x > 0. Then for 0 < x < √2, a rectangle circumscribed by the x-axis and the parabola y = 2 - x² has a length of 2x and a height of 2 - x², so its area is
A(x) = 2x (2 - x²)
Differentiate A with respect to x :
A'(x) = 2 (2 - x²) + 2x (-2x)
A'(x) = 4 - 6x²
Find the critical points:
4 - 6x² = 0
6x² = 4
x² = 4/6 = 2/3
x = √(2/3)
Check the sign of the second derivative at this point to confirm that it's a maximum:
A''(x) = -12x
The second derivative is negative for all x > 0, so x = √(2/3) is indeed a maximum.
So the rectangle with maximum area has dimensions
width/length = 2 √(2/3)
height = 2 - (√(2/3))² = 4/3

Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 3 1/2 times more than the rainfall during September of the same year. How much rain fell during the month of September?
Answer:
4in
Step-by-step explanation:
Given
Amount of rain that fell in October = 14in
If this value is 3 1/2times amount of rain that fell in September, we can express it mathematically as;
3 1/2 of September = 14
7/2 of x = 14
x is the amount of rain that fell in September
From the expression
7x/2 = 14
Cross multiply
7x = 14×2
7x = 28
Divide both sides by 7
7x/7 = 28/7
x = 4in
Hence the amount of rain that fell in September is 4in

I need a person or a tutor that’s willing to get my number to help me with my math and with these questions bc I really need help
Answer:
Slope is -5/3, the y intercept is 5
Step-by-step explanation:
If you want to find cordinates you first have to solve the equation so that it is in the form mx+b=y
solve for y
5x+3y=15
-5x -5x
3y =-5x+15
3y/3 = -5x/3+15/3
y=-5/3x+5
or -5/3x+5=y
Now you know that the slope is -5/3 and the y intercept is 5
Start for 5 on the cordinate plain and go down 5 since it is negative and go to the right 3.
after you get to the bottom right of the graph you go back to 5 and just do the exact opposite of what you did above.
so go up 5 and go to the left 3 and continue until you get to the top left of the graph.
The cost of a bagel at Tim Horton’s is $0.99 and the cost of a large coffee is $1.29. If Derek purchases 4 more bagels than large coffees and spends $10.80 total, how many of each did he purchase?
Answer:
7 Bagels and 3 Large Coffee
Step-by-step explanation:
Represent Large Coffee with L and Bagel with B.
We have that:
[tex]0.99B + 1.29L = 10.80[/tex] ---- Amount spent
and
[tex]B = L + 4[/tex] ---- Quantity
Required
Determine the value of L and B
Substitute L + 4 for B in the first equation
[tex]0.99B + 1.29L = 10.80[/tex]
[tex]0.99(4 + L) + 1.29L = 10.80[/tex]
Open Bracket
[tex]3.96 + 0.99L + 1.29L = 10.80[/tex]
[tex]3.96 + 2.28L = 10.80[/tex]
Collect Like Terms
[tex]2.28L = 10.80 - 3.96[/tex]
[tex]2.28L = 6.84[/tex]
Solve for L
[tex]L = 6.84/2.28[/tex]
[tex]L = 3[/tex]
Recall that
[tex]B = 4 + L[/tex]
[tex]B = 4 + 3[/tex]
[tex]B = 7[/tex]

A disinfectant spray bottle eliminates 90%of bacteria each application. If you apply once on counter top then apply another on the same countertop. What percentage of bacteria has been eliminated?
Answer:
I'd say still 90%
Step-by-step explanation:
The other 10% of bacteria that was left over was probably immune or unaffected by the disinfectant, hence why the spray didn't kill 100% to begin with.
Its similar to hand sanitizer, It kills 99.99% of germs because one germ is always immune or unaffected by it. Hope that makes sense and helps!

y=4x+30
Answer: y = 30x + 4 (/1)
Step-by-step explanation:
30 is the y intercept because it says its' the startup fee. Therefore it must be the y intercept.
4 must be the gradient. Basically, on a Cartesian plane, the y intercept will be on 30. Move 4 digits up and 1 to the left continually
f = 0.9 Hz and v = 154.9 cm/s
The wavelength of a wave is 1.72 m.
Given,
Frequency, f = 0.9 Hz
Speed of a wave, v = 154.9 cm/s = 1.549 m/s
So, the wavelength of a wave is 1.72 m. Hence, the attachment is the required solution.
