Step-by-step explanation:
The ratio of students to laptops in a school is 3:2. If there are 1,200 students, how many laptops are there?
Una fábrica produce tres tipos de balones de fútbol, con un costo mensual de
$24,250.00 por cada 1125 balones. Los costos de fabricación son $ 40.00, $ 30.00 y $
20.00. Estos balones se venden en $ 160.00, $ 120.00 y $ 100.00, respectivamente.
¿Cuántos balones de cada tipo se fabrican si la ganancia mensual es de $ 92,750.00?
Answer:
Se fabricaron:
1000 balones de los que cuestan $20
75 balones de los que cuestan $30
50 balones de los que cuestan $40
Step-by-step explanation:
Vamos a definir las variables:
x = número de balones de $100.00 vendidos.
y = número de balones de $120.00 vendidos
z = número de balones de $160,00 vendidos.
Sabemos que se producen 1125 balones, entonces:
x + y + z = 1125
y el costo de producción es $24,250, conociendo el costo de cada balón podemos escribir:
x*$20 + y*$30 + z*$40 = $24,250
Y también sabemos que la ganancia mensual es $92,750
Ganancia es la diferencia entre el dinero total recibido y los costos, entonces:
x*$100 + y*$120 + z*$160 - $24,250 = $92,750
x*$100 + y*$120 + z*$160 = $92,750 + $24,250
x*$100 + y*$120 + z*$160 = $117,000
Entonces tenemos un sistema de 3 ecuaciones:
x + y + z = 1125
x*$20 + y*$30 + z*$40 = $24,250
x*$100 + y*$120 + z*$160 = $117,000
Para resolver esto debemos comenzar por aislar alguna variable en alguna de las ecuaciones, yo comenzare aislando x en la primera ecuación:
x = 1125 - y - z
Ahora podemos reemplazar esto en las otras dos ecuaciones para obtener:
(1125 - y - z)*$20 + y*$30 + z*$40 = $24,250
(1125 - y - z)*$100 + y*$120 + z*$160 = $117,000
Si simplificamos esto obtenemos:
$22,500 + y*$10 + z*$20 = $24,250
$112,500 + y*$20 + z*$60 = $117,000
Ahora de vuelta, debemos aislar una variable en una de las ecuaciones, si aislamos y en la primera ecuación obtenemos:
y*$10 = $24,250 - $22,500 - z*$20
y = ($1,750 - z*$20)/$10
y = 175 - 2*z
Reemplazando esto en la otra ecuación obtenemos:
$112,500 + (175 - 2*z)*$20 + z*$60 = $117,000
Ahora podemos resolver esto para z.
(175 - 2*z)*$20 + z*$60 = $117,000 - $112,500
(175 - 2*z)*$20 + z*$60 = $4,500
$3,500 - z*$40 + z*$60 = $4,500
$3,500 + z*$20 = $4,500
z*$20 = $4,500 - $3,500 = $1,000
z = $1,000/$20 = 50
Entonces tenemos 50 balones de los que cuestan $40.
Usando la ecuación y = 175 - 2*z podemos encontrar el valor de y.
y = 175 - 2*50 = 75
Entonces tenemos 75 balones de los que cuestan $30.
Usando la ecuación x = 1125 - y - z podemos encontrar el valor de x.
x = 1125 - 75 - 50 = 1000
tenemos 1000 balones de $20.
When ax3+bx-6 is divided by x+3,the remainder is 9. Find term of a only . The remainder when 2x3-bx2+2ax-4 when it is divided by x-2
Answer:
a) a = - ( 5 + b ) / 9
b) no remainder
Step-by-step explanation:
A) ( ax^3 + bx -6 ) / ( x + 3 )
Remainder = 9
determine the value of a
we will use the result of if ( x + a ) divides polynomial g(x) the remainder is g(a)
therefore given that ( x + 3 ) divides f(x) = ax^3 + bx - 6
= f( -3 ) = 9
= a(- 27 ) - 3b - 6 = 9
= -27a = 9 + 6 + 3b
therefore the term 'a' = - ( 15 / 27 + 3b / 27 )
= - ( 5/9 + b/9 )
a = - ( 5 + b ) / 9
b) Find the remainder when (2x^3 - bx^2 + 2ax - 4 ) is divided by (x-2 )
given that ( x -2 ) divides f(x) = 2x^3 - bx^2 + 2ax - 4
also given a = - ( 5 + b ) / 9 from previous polynomial above
= f(2) = ?
= 2(8) -4b + 4a - 4
= 16 - 4b + 4 ( - ( 5 + b ) / 9 ) - 4
= 16 - 4b + (( -20 - 4b ) / 9) - 4
= 16 - 4b - ( 20 - 4b ) / 9) - 4
= 16 - ( 32b - 20 ) / 9) - 4 = ?
therefore the remainder 'b' = ( -108 + 20 ) / 32 = - 2 3/4
since the remainder is negative there is no remainder then

Hakan is standing next to a building whose shadow is 15 feet long. If Hakan is 6 feet tall and is casting a shadow 2.5 feet long, how high is the building?
Height of Building = Feet
answer:
Answer:
36 feet long
Step-by-step explanation:
When you get the question it should look like this: 6/2.5 X/15.
Your gonna have to cross multiply 6 and 15 the keep 2.5 and X like this: 2.5x
After that, it should look like this: 2.5x=90, Now your gonna wanna divide 90 and 2.5 which you will get 36.
X= 36 ft long.

What is the height of a cone with a slant height of 16 inches and a radius of 6 inches? Round your answer to the nearest whole number.
Answer:
14.8 inches
Step-by-step explanation:
Given that:
Slant height, l = 16 inches
Radius, r =. 6 inches
Using the relation :
h² + r² = l²
h² + 6² = 16²
h² = 16² - 6²
h² = 256 - 36
h² = 220
h = sqrt(220)
h = 14.832
h = 14.8 inches

Josh is selling crafts at an outdoor market. He charges $2.25 for each door hanger he has made and $3.75 for each necklace. He knows he has sold at least 20 items at the market, but he has no more than $60 in sales.
Answer:
He sold 10 hangers and 10 neclesses
Step-by-step explanation:
Given data
Let the number of door hanger be x
and the number of neckless be y
so
x+y= 20---------1
also,
2.25x+3.75y= 60---------2
Solve 1 and 2 together
From 1
x= 20-y
put this in place of x in 2
2.25(20-y)+3.75y= 60
45-2.25y+3.75y= 60
1.5y= 60-45
1.5y= 15
y= 15/1.5
y= 10
Put y= 10 in 1
x+10= 20
x= 20-10
x= 10
help please I have too many points and I also need help on my math
Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.
I hope this helps! Feel free to ask any questions!

question: write the function as an equation, the function is linear btw
Answer:
y - 8 = 4(x - 2)
Step-by-step explanation:
Note that as we increase any x value by 1, the corresponding y value increases by 4. Thus, the slope is 4.
Using the slope-intercept formula, we get:
y - 8 = 4(x - 2)
Check: If x = 5, does this formula result in y = 20?
y = 8 + 4(x - 2) with x = 5 comes out to y = 8 + 4(3) = 8 + 12 = 20. YES
How many learners can enrol if there are 12 teachers and a ratio of teachers to learners is 30:1
Answer:
360 learners
Step-by-step explanation:
One way to solve these types of problems is that you could set up a proportion
learners/teachers = learners/teachers
Let x = no. of learners to enrol
30/1 = x/12
12(30) = x
x = 360 learners

Given a set of attributes, can you make one triangle, no triangles, or many triangles?
jo says, "the attributes of my triangle are sides that are 3cm and 9cm long. I can make only one triangle because I have to connect the ends of my two sides."
do you agree or disagree? why?
Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

Two glasses of milk and 3 snack bars have a total of 62 carbohydrates, and 3 glasses of milk and 2 snack bars have a total of 58 carbs. Determine how many carbs are in one glass of milk in one snack bar.
Step-by-step explanation:
So looking at this question, we have two variables (1 - a glass of milk; 2 - a snack bar) and two equations to use to solve for the two variables. Remember that for any number of variables, you need that same number or more equations to solve for the variables.
Let's say that a glass of milk is represented by g and a snack bar is represented by s.
So we essentially have two equations here:
4 glasses of milk + 3 snack bars = 88 carbs, or:
4g + 3s = 88
2 glasses of milk + 4 snack bars = 74 carbs, or:
2g + 4s = 74
Now that we have this, we can solve for our equations. There are two ways to do this:
SUBSTITUTION - solve for one variable, then substitute it in
Let's solve for g using the second equation. First, we'll isolate g by subtracting 4s from both sides.
2g = 74 - 4s
Next, we can divide the whole equation by 2 to solve for g.
g = 37 - 2s
Now, we can substitute this into the first equation for g and solve for s.
4g + 3s = 88
4(37 - 2s) + 3s = 88
148 - 8s + 3s = 88
148 - 5s = 88 (now subtract 88 from both sides and add 5s to both sides)
60 = 5s
s = 12
Now we can use this to solve for g in the original equation
g = 37 - 2s
g = 37 - 2(12) = 37 - 24 = 13
ELIMINATION - eliminate one variable to solve for the other, then use that to solve for the first
Let's look at our two equations
4g + 3s = 88
2g + 4s = 74
Let's eliminate the variable g first by multiplying the second question by -2.
4g + 3s = 88
-4g - 8s = -148
If we add these two equations together, we get
-5s = -60
Divide both sides by -5 and we get
s = 12
Now, we can plug s into either equation to solve for g as we did above.
