Answer: cage I
Step-by-step explanation:
Given
43 gm of copper and 7 gram of other metal
Another cage has 83 gram of copper and 17 gm of other metals
Here, the percentage of copper is
For the first case
[tex]\Rightarrow \dfrac{43}{43+7}\times 100=86\%[/tex]
For the second case
[tex]\Rightarrow \dfrac{83}{83+17}\times 100=83\%[/tex]
So, the cage-I has more percentage of copper

An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

A plane is at cruising altitude of 10,200 feet. If the angle of depression to the run way is 18 degrees, what is the distance, to the nearest foot, from the plane to the run way
Answer: [tex]33,007.9\ ft[/tex]
Step-by-step explanation:
Given
The plane is cruising at an altitude of [tex]h=10,200\ ft[/tex]
The angle of depression is [tex]\theta=18^{\circ}[/tex]
Suppose the distance of the plane to the runway is x
from figure
[tex]\Rightarrow \sin 18^{\circ}=\dfrac{h}{x}\\\\\Rightarrow \sin 18^{\circ}=\dfrac{10,200}{x}\\\\\Rightarrow x=33,007.9\ ft[/tex]

What is the scale factor from AABC to ADEF?
Answer:
C. 1/12
Step-by-step explanation:
The scale can be calculated by comparing side lenghts
AC is similar to FD and AB is similar to FE and BC is similar to ED
AB = 2 and FE = 24 so AB/FE is = 2/24 that's simplified is 1/12

The density of an object is equal to the quotient of its mass, and volume. An object has a density of 10g per liter and a volume of 40 liters. What is its mass in grams.
Answer:
400 grams
Step-by-step explanation:
If the equation is density = mass / volume, fill it out to find mass
10 = x / 40
400 = x
x = 400 g
How do you solve:
g(x) = x - 2
( I think the answer is 2 but how?!)
Answer:
x-2 =0
x=2
Step-by-step explanation:
we take -2 to the anther side it becomes 2
Answer:
-2
Step-by-step explanation:
A function is a rule for working out the values y for the given values x
For example, h = 3x and y = x^2 are functions. The notation g(x) is read as g of x. g is the function. g(x) = 3x means the function of x is 3x
So, when solving to find the value of x, you must substitute x for any given value.
For example, f(x) = 10/x. Work out f(5), you must substitute the 5 into the denominatior of the fraction 10/x . This becomes 10/5, which equals to 2.
But for your question, to find the value of x, substitute x with 0
You end up with -2
Hope this helps

ed made a large cube by gluing together a number of identical small cubes together
Answer:
thats cool not realy a question tho can I have brainlest
Step-by-step explanation:
Ed painted 95 faces of a large cube.
What is the Cubic equation?Cubic equations are polynomials of degree 3. That means the maximum degree of the polynomial is three.
And the standard form of the cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c, and d are constant coefficients a ≠ 0.
Let's assume that the original cube that Ed made had n small cubes along each edge.
Then the total number of small cubes in the large cube is n³.
Let p be the number of faces that Ed painted.
Each small cube has 6 faces, and if a face is painted, it will not be visible after the large cube is assembled.
So the total number of unpainted faces is 6n³ - p.
When Nicole drops the cube, each small cube will be separated from the others, and all painted faces will become visible.
So the total number of painted faces is equal to p minus the number of small cubes that don't have any painted faces, which is 45.
Therefore, we have a cubic equation:
p - 45 = 6n³ - p.
Simplifying this equation, we get:
2p =6n³ + 45
p = 3n³ + 22.5
We know that p is an integer, so 3n³ + 22.5 must be an integer.
This means that n³ must be a multiple of 2/3.
The smallest integer value of n that satisfies this condition is n = 3.
So Ed made a cube with 3 small cubes along each edge, and he painted:
the value of the cubic equation at 27,
p = 3n³ + 22.5 = 3(27) + 22.5 = 94.5 ≈ 95 faces of the large cube.
Therefore, 95 faces of the large cube.

The complete question:
Ed made a large cube by gluing together a number of small identical cubes and then he painted some of the faces of the large cube. His sister Nicole dropped the cube and it broke into the original small cubes. 45 of these small cubes didn't have any painted faces. How many faces of the large cube did Ed paint?
The Wheelers’ bill at a restaurant is $63.00. How much total money is Mr. Wheelers' lunch if he plans to tip 15%?
asap besties
we know that
when you want to figure out a tip, you take your total bill and multiply it by the percentage you would like to tip them
so
15%=15/100------> 0.15
$63*0.15=$9.45
the answer is
$9.45

Solve the system of equations 3x+2y=223x+2y=22 and -4x+3y=16−4x+3y=16 by combining the equations.
Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)
