Answer:
100%
300 students
Step-by-step explanation:
let b = number of students in the school
this equation can be derived = 10% x b = 30
to find b, divide both sides of the equation by 10%
b = 30/0.1 = 300
we want find the total number of students in the school, which is equal to 100%

What fraction is equal to 40% ?
Your Answer is:
4/10
Step-by-step explanation:
because 4 out of 10=40%...
Please help will give brainliest
Answer:
D
Step-by-step explanation:
40% = [tex]\frac{40}{100}[/tex] = [tex]\frac{2}{5}[/tex] ← in simplest form
Then
[tex]\frac{2}{5}[/tex] of $120 = [tex]\frac{2}{5}[/tex] × $120 = 2 × $24 = $48
she pays $120 - $48 = $72

Two numbers, x and y, have a sum of 8 and a difference of –14. A. Write a system of equations that can be used to determine the values of x and y. B. Solve the system of equations. Show your work.
Answer:
The system is:
x + y = 8
x - y = -14
And the solution is:
x = -3
y = 11
Step-by-step explanation:
We have two numbers x and y, such that:
x + y = 8 (the sum is equal to 8)
x - y = -14 (the difference is equal to -14)
This is the system of equations we need to solve.
To solve the system, we first need to isolate one of the variables in one of the equations, I will isolate x in the first equation:
x = 8 - y
Now we can replace this in the other equation to get:
(8 - y) - y = -14
8 - 2*y = -14
8 + 14 = 2*y
22 = 2*y
22/2 = y
11 = y
Now we can replace this in the equation "x = 8 - y"
To get:
x = 8 - 11 = -3
Then the solution to the system is:
x = -3 and y = 11
what is 2 3/4 as an improper factor..? just asking
Answer:
11/4
Hope this helps
Answer:
11/4
Step-by-step explanation:
An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.
You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8
then we add 8/4 with 3/4 to get 11/4

During halftime of a football game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 4 feet with an initial upward velocity of 80 feet per second. The T-shirt is caught 41 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time?
9514 1404 393
Answer:
time to max height: 2.5 seconds
max height: 104 ft
range of function: [4, 104]
Step-by-step explanation:
The equation for ballistic motion is ...
h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height
For the given parameters, the height function is ...
h(t) = -16t^2 +80t +4
The time for maximum height is ...
-b/(2a) = -80/(2(-16)) = 2.5 . . . seconds
The maximum height is ...
h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet
The range of the function is from the minimum height (at launch) to the maximum height:
4 ft ≤ h(t) ≤ 104 ft.

Answer:
(x,y) = (-2,7)
Step-by-step explanation:
7x+2y=0
9x+4y=10
y = -9x/4 + 5/2
7x+2 (-9x/4 + 5/2) = 0
5x/2 = -5
5x = -10
x = -2
use x and substitute to get y
y = -(9/4) (-2) +5/2 = 7

Kate conducts a survey at her middle school to determine the students' favorite sport. Which sampling method would best produce a representative sample of the population?
Incomplete question. The missing options read;
a. Kate surveys every 8th student from a roster of the choir members.
b. Kate surveys the football team.
c. Kate surveys seventh-grade students.
d. Kate surveys every 4th student entering the school.
Answer:
d. Kate surveys every 4th student entering the school.
Step-by-step explanation:
Interestingly, after careful examination of all the listed sampling methods, none except option d would best produce a representative sample of the population.
This is because;
in the first, second, and third option, none of them evenly represents the entire school population; meaning it fails to produce a representative sample of the population.
However, if Kate surveys every 4th student entering the school, then chances of getting a representative sample of the entire school population are very likely; as different grade level students would likely be entering into the school when the survey activity is taking place.
PLEASE HELP!! school is over in a week for me and i have A LOT of work to be done, IM BEGGING!! NO LINKS OR FILES!!!!!
Answer:
System of equations
160 = 2W + 2L
W = L - 16
Solution to system of equations
W = 32 ft
L = 48 ft
Explanation:
The width is 16 feet less than the length, so the appropriate equation for that is ...
... W = L - 16
Using this expression for W, we can substitute into the equation for perimeter:
... 160 = 2(L - 16) + 2L
... 160 = 4L -32 . . . . . . . collect terms
... 192 = 4L . . . . . . . . . . add 32
... 48 = L . . . . . . . . . . . . divide by 4
... W = 48 -16 = 32 . . . . find W using the relation with L
Length is 48 ft; width is 32 ft.

Ana compró una cartera cuyo precio original es de x dólares con el 10% de descuento y un perfume con precio original de B dólares con un descuento del 15%¿cuanto gasto en total Ana?
Answer:
Tarea:
Ana compró una cartera cuyo precio es x dólares con el 10% de descuento y un perfume con precio original en dólares con un descuento del 15%. ¿Cuánto gastó Ana en total?
- Solución:
El precio estará en lenguaje algebraico, ya que no nos dan el dato de cuánto costó cada artículo.
• Hallamos el precio de la cartera con el descuento:
El precio original es x, entonces:
Regla de tres:
100 % --------> x
10 % -----------> ?
10 . x : 100 = ?
10x/100 = ?
El 10% del precio de la cartera es 10x/100.
Entonces el precio de la cartera es (x-10x/100).
• Hallamos el precio del perfume con el descuento:
El precio original es y, entonces:
Regla de tres:
100% -------> y
15 % --------> ?
15.y/100
El 15% del perfume es 15y/100.
Entonces el precio del perfume con el descuento es (y-15y/100).
Entonces lo que gastó en total es:
(x - 10x/100) + (y - 15y/100)

Multiply both polynomials together
Answer:
6x + 11x - 10
Step-by-step explanation:
So in order to solve this expression, we have to distribute the numbers in each set of parenthasis
Step 1 : break down each mini-espression you're solving
(2x+5)(3x-2)
each term is multiplied by both terms in the other set of parenthasis.
(2x · 3x) + (2x · -2) + (5 · 3x) + (5 · -2)
Step 2 : Solve each idividual piece
(2x · 3x) = 6x²
(2x · -2) = -4x
(5 · 3x) = 15x
(5 · -2) = -10
Step 3 : Put it all together amd simplify
6x² - 4x + 15x - 10
6x² + 11x - 10
A plane is traveling at a constant rate described by d = 525t where d is the distance and t is the time. How long will it take the plane to travel 3150 miles?
Answer:
6 hours
Step-by-step explanation:
Given: A plane is traveling at a constant rate described by d = 525t
where d is the distance and t is the time
We know that ratio of distance upon time = d/t = 525 miles per hour
Therefore, time taken to travel 3150 miles = 3150/525 = 6 hours
Nieves y Ana juegan tres partidas partidas. Nieves tenía 10 cromos y Ana 80. En la primera partida ganó Nieves y elevó sus cromos al cuadrado, en la segunda perdió el cubo de 3, y en la tercera perdió el cuadrado de 4. ¿Cuántos cromos les quedan a Ana y a Nieves?¿Quién ha ganado?
Answer:
A Nieves le quedan 57 cromos y a Ana 33.
Nieves ha ganado 47 cromos
Step-by-step explanation:
Para la primera partida, el cuadrado de los cromos de Nieves es de 100.
El cubo de 3 es 27. Nieves queda con 100-27 = 73 cromos
El cuadrado de 4 es 16. Nieves queda con 73-16 = 57 cromos
A Nieves le quedan 57 cromos
A Ana 90-57 = 33 cromos
Así, Nieves ha ganado 57-10 = 47 cromos
