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?

If you currently make 3200 per month and you are given a raise to 3400 per month, what is the percent change of your salary?
Answer:
6.25%
Step-by-step explanation:
% change= (chnage/original salary) × 100%
Change = new salary - original salary
Hence = 3400-3200=200
% change= (200/3200)×100%= 6.25%

Answer:
A
Step-by-step explanation:
143.6° and x are adjacent angles and sum to 180° , then
x + 143.6° = 180° ( subtract 143.6° from both sides )
x = 36.4° → A

A worker earns $9 per hour and works 25 hours each week. If the worker receives a 3% pay increase, how much additional pay will the worker earn each week?
Answer: $6.75
Step-by-step explanation:
25 hours times $9= $225/week
3% increase from $9.00= $0.27
$9.27 times 25 hours= $231.75
$231.75-$225= $6.75 more per week

Bradley works at a restaurant, earning a daily salary and tips per table served. The scatter plot shows how much money he earned, in dollars,
related to the number of tables served. A line of best fit for Bradley's data is shown.
y 4
No links just an answer pls help
Answer:
For every table served, Bradley's pay increases by an average of 4
Step-by-step explanation:
The line of best fit for the graph is y = 4x + 25 ; where, y = total pay and x = tables served
Using the slope intercept relation : y = mx + c ; where, m = slope
y = 4x + 25 ; the slope of the graph is 4
This means the rate of change of x with respect to y is 4 ;
This means for every unit change in x ; y increases by 4
For every table served, total pay increases by 4

Find the 9th term of the geometric sequence 3, -15, 75,
Answer:
1,171,875
Step-by-step explanation:
I got this as my answer because this geometric sequence follows the pattern of times -5. So, I followed the pattern until I got the 9th term.
3
-15
75
times -5 -> -375
times -5-> 1,875
times -5-> -9,375
times -5-> 46,875
times -5-> -234,375
times -5-> 1,171,875
So, the 9th term of the geometric sequence is 1,171,875.

Find the value of v (velocity) and V (volume) from the following equations.
a) v = u + at
Where u = 40, a = - 6, t = 4
( PLEASE HELP FAST)
Answer:
16m/s
Step-by-step explanation:
Given data
u = 40,
a = - 6,
t = 4
Let us substitute into the given expresssion to find v
v = u + at
v = 40+ -6*4
v= 40+ (-24)
v= 40-24
v= 16m/s
Electric current flowing through wire produces heat that varies jointly as the resistance of the wire and the square of the current. The resistance of two wires are in the ratio
2:3. What current passing through the second wire will produce the same amount of heat as a current of 6 amperes
through the first wire?
It has the same slope as y=5x+3 and passes through (1, 5).
Answer:
y=5x
Step-by-step explanation:
Because it has the same slope, both equations must have 5x as their slope. The 2 equations are not going to have the same y intercept, so the +3 can be ignored and replaced with b. You want to plug in (1,5) into you new equation of y=5x+b, to get 5=5(1)+b. Multiply 5 by 1 to get 5, and then subtract 5 from both sides, which gives you 0=b. This means that the y intercept is the origin, so your new equation is y=5x
A school sport's team sold hats for $12 each hat. The team made a profit of $3 for each hat sold. What percent of the selling price of each hat is the profit?
Answer: 25%
Step-by-step explanation:
Given: Selling price of each hat = $12
Profit on each hat = $3
To find: The percent of the selling price of each hat is the profit.
Ratio of profit to selling price = [tex]\dfrac3{12}=\dfrac14[/tex]
The required percentage = Ratio of profit to selling price x 100
[tex]=\dfrac14\times100=25\%[/tex]
The profit is 25% of the selling price.
