Answer:
x = 25.
Step-by-step explanation:
Original cost per person:: 2000/x
Changed cost per person:: 2000/(x-5)
---------------------------
Equation:: changed - original = 20
2000/(x-5) - 2000/x = 20
2000x - 2000x + 2000*5 = 20x(x-5)
10000 = 20x^2-100
----
500 = x^2 - 5x
------------------
x^2 - 5x - 500 = 0
(x+20)*(x-25) = 0
-----
Only positive root makes sense ====> x = 25.
A sculpture is made of solid copper in the shape of a cone. The sculpture is 67 inches tall, and its base has a radius of 15 inches. If copper costs 1.06$ per cubic inch, how much did the copper for the sculpture cost?
Use 3.14 for Pi, and do not round your answer.
Answer:
$16,725.21
Step-by-step explanation:
To get the cost of the copper used for the sculpture, we must first determine the volume of the object which is given as a cone
Recall that the volume V of a cone
= 1/3Pir^2h
where r is the base radius and h is the height
Given that the sculpture is 67 inches tall, and its base has a radius of 15 inches, the volume of the sculpture
= 1/3 * 3.14 * 15^2 * 67
= 15,778.5 cubic inch
If copper costs 1.06$ per cubic inch, then the cost of the copper for the sculpture
= 15,778.5 * 1.06
= $16,725.21

Which function has an asymptote at x = 5 and an x-intercept of (6,0)?
OA
f(x) = log(x - 5)
B.
f(x) = log(x + 5)
OC. Ax) = log x-5
OD.
f(x) = log x + 5
Answer:
f(x) = log (x-5)
Step-by-step explanation:
__________
f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)
What is a function?A relation is a function if it has only One y-value for each x-value.
we need to find the function which has an asymptote at x = 5 and an x-intercept of (6,0)
An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity.
There are three types of asymptotes: vertical, horizontal and oblique.
The asymptotes are lines, they are written as equations of lines. The vertical asymptotes are x = 5.
f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)
Hence, f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)

Answer:
180
Step-by-step explanation:
area of a trapezoid = [tex]\frac{a+b}{2}h[/tex]
where a = base 1
b = base 2
and h = height
This is what we are given
base 1 = 23
base 2 = 37
and height = 6
That being said we plug in the given values into the formula
[tex]A=\frac{37+23}{2} 6\\23+37=60\\\frac{60}{2} =30\\30*6=180[/tex]
Hence the area of the trapezoid is 180 square feet

Missy and Bill were asked to evaluate the expression -3(-2 + 5).
Answer:
-9
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
using BODMAS, our mathematical operation begins with the bracket.
it implies that from -3(-2+5), we solve the bracket.
-2+5=3
then our mathematical operation is the 'of' operation.
it implies that -3(3) = -9
Answer is -9

Si a la mitad de un número le restas su tercera parte, y, a este resultado, le sumas 85/2,
obtienes el triple del número inicial. ¿De qué número se trata?
Answer:
x = 15
Step-by-step explanation:
Llamaremos x al número que buscamos, entonces:
la mitad de x es x/2, la tercera parte es x/3, y el triple del número es 3*x
De acuerdo al problema :
(x/2 - x/3 ) + 85/2 = 3*x
Esta es una ecuación de primer grado pasamos a resolverla.
( 3*x - 2*x ) /6 + 85/2 = 3*x
x/6 + 85/2 = 3*x
( x + 255)/6 = 3*x
x + 255 = 18*x
17*x = 255
x = 255/17
x = 15

Melissa has 120 vanilla cake pops to sell. Each vanilla cake pops is covered with one topping. 1/2 of the cake pops are covered with chocolate sprinkles. 1/3 of the cake pops are covered with strawberry sprinkles. * the rest are covered with green sprinkles. How many cake pops are covered with green sprinkles?
Answer:
The Answer is 20 cake pops are covered with green sprinkles.
Step-by-step explanation:
So if you have 1/2 choclate, 1/3 strawberry, and the rest are green, you first need to convert the Chocolate and the Strawberry into the same fraction. As shown:
Chocolate: 1/2=3/6
Strawberry:1/3=2/6
The rest are Green sprinkles.
So, your equation would be:
Chocolate sprinkles + Strawberry Sprinkles + Green Sprinkles = Total
And their are 5/6 of Chocolate and Strawberry Sprinkles...
That would mean 100 Chocolate and Strawberry Sprinkles!
Because 1/6 of 120 is 20 and multiply that by five and you have 100...
Now that we have that, and we know the rest are green...
we just do 120-100=20
So their you go!
