3 x 3 x 3 cube is painted and it is cut into 27 cubes how many small cubes will have paint on exactly two faces
Answer:
12
Step-by-step explanation:
See attached picture. We have a 3x3x3 cube. If we cut it into 27 cubes, we will end up with a rubik's cube like cube. Each of the small cubes will measure 1x1x1. So if we pay close attention to the cube, we will see that only the cubes on the edges will have two of its faces painted in two colors. We can think of the cube as having three layers. Each of the layers will have 4 edge cubes, so we will have in total:
3x4=12 cubes that will have only two of its faces with paint on them.
What is the equation of the line whose Y intercept is 3 and slope is 1?
A) Y=x-3
B) Y=x+3
C) Y=3x+1
Answer:
y=x+3
Step-by-step explanation
The slope intercept form equation is y=mx+b. m is the slope and b is the y intercept. In this scenario, plug it back in to m and b. m=1 and b=3 so it would be y=1x+3. However, we don't include the one so it would just be y=x+3

Answer:
The equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]The equation of the line passes through (3, -2) and perpendicular to the given line:
[tex]y=-\frac{1}{3}x-1[/tex]Step-by-step explanation:
Given the points on the graph line
(2, -1)
(1, -4)
Finding the slope between (2, -1) and (1, -4)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:-4\right)[/tex]
[tex]m=\frac{-4-\left(-1\right)}{1-2}[/tex]
[tex]m=3[/tex]
Equation of the line passes through (3, -2) and parallel to the given line.
We know that parallel lines have the same slope.
so the equation of the line parallel to the given line = 3
Thus, using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 3 and the point (3, -2)
[tex]y - (-2) = 3(x-3)[/tex]
[tex]y+2 = 3x-9[/tex]
[tex]y = 3x-9-2[/tex]
[tex]y = 3x-11[/tex]
Therefore, the equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]
The equation of the line passes through (3, -2) and perpendicular to the given line
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 3
perpendicular slope = – 1/m = -1/3 = -1/3
Therefore, substituting the values of perpendicular slope = -1/3 and the point (3, -2) in the point-slope form of the line equation
[tex]y-\left(-2\right)=-\frac{1}{3}\left(x-3\right)[/tex]
[tex]y+2=-\frac{1}{3}\left(x-3\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=-\frac{1}{3}\left(x-3\right)-2[/tex]
[tex]y=-\frac{1}{3}x-1[/tex]
Therefore, the equation of the line passes through (3, -2) and perpendicular to the given line:
[tex]y=-\frac{1}{3}x-1[/tex]
Conclusion:
The equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]The equation of the line passes through (3, -2) and perpendicular to the given line:

What is the area of rectangle?The area of the rectangle is the region enclosed by the perimeter of the rectangle and is equal to product of length and width. The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'.
So, the Area of Rectangle = (a × b) square units.
The area of a rectangle is length ✕ width.
So, width = area/length
length = 7.2 ft
width = 5.8ftnumber of office = 4
Area of one office = 7.2 * 5.8 Area of one office = 43.5ft^2

When we compare two fractions with the same numerator, which
statement below is true?
А
The fractions with the same
numerators are the same.
11
The fraction with the smaller
denominator is the larger fraction.
C
The fraction with the larger
denominator is the larger fraction.
D.
We cannot say which is larger or
smaller than the other.
Answer:
The fraction with the smaller denominator is the larger fraction.
Step-by-step explanation:
Let's take [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{10}[/tex]. The larger the denominator, the more the number of pieces. So if you have a pizza box divided into 6 slices, and they are all the same size, compared to that same box of pizza divided into 10 slices. Each of those 10 slices will be smaller than the 6 slices. Now if you eat 5 of the 6 slices, compared to if you eat 5 of the 10 slices, which one will make you more full and you know that you have eaten a lot? Of course, it is the 5 out of 6 slices because each of those slices is bigger. So the smaller the denominator of the fraction, the larger it is (if the numerator stays the same).

Maurice takes a roast out of the oven when the internal temperature of the roast is 165F after ten minutes , the temperature roast drops to 145
The above question is incomplete
Complete Question
Maurice takes a roast out of the oven when the internal temperature of the roast is 165°F. After 10 minutes, the temperature of the roast drops to 145°F.
The temperature of the room is 72°F.
How long does it take for the temperature of the roast to drop to 120°F?
Answer:
27.3143 minutes
Step-by-step explanation:
Using the Newton's law of cooling: The formula is given as:
T (t) = T₀ + T₁ e^ (rt)
Where
T₀ = Original temperature of the room (°F) ; 72°F
T₁ = Temperature of the roast (°F)
This is calculated as:
165 - 72 =93°F
r = Rate of cooling (°F/min)
t = time (min)
Substituting the values, we can obtain:
T (t) = 72 + 93 e ^rt
Step 1
We solve for r
From the question, we know that: the temperature dropped to 145°F after 10 minutes,
t =10 mins and T(10) = 145 °F
Substituting
T(10) = 72 +93 e^10r
145 = 72 + 93 e^10r
145 - 72 = 93 e^10r
Divide both sides by 93
(145-72)/93 = e^(10r)
We take the natural logarithm of both the left and right hand sides
In [(145-72)/93 ] = In (e^10r)
In [(145-72)/93 ] = 10r
-0.24214 =10r
r = -0.24214/10
r = -0.02421 °F/min
Substituting into
-0.02421 °F/min for r in the Equation below
T (t) = 72 + 93 e ^rt
T (t) = 72 + 93 e^ (-0.024214t)
To find the time taken to reach 120°F, we substitute into equation
120 = 72 +93 e^(-0.024214 ×t)
(120-72)= 93 e^ (-0.024214t)
Divide bother sides by 93
[(120-72)/93] = e^-0.024214t
We take the natural logarithm of both sides
In[(120-72)/93] = In(e^-0.024214t)
-0.66139 = -0.024214t
Divide both sides by -0.024214t
t = -0.66139/ -0.024214
t =27.3143 minutes

Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=1001.06t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=1001.06t[/tex]
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
[tex]b(3)=1001.06(3)[/tex]
[tex]b(3)=3003.18[/tex]
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
[tex]b(3)\approx 3003[/tex]
Therefore, the number of total bacteria after 3 hours is about 3003.

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there
Answer:
60,949,324,800
Step-by-step explanation:
We solve the above question using Permutation formula
The formula for Permutation =
nPr = n!/(n - r)!
Total Amount in a Set (n) = 20 persons
Amount in each Sub-Set (r) = 9 batting order
Hence:
20P9 = 20!/(20 - 9)!
= 60,949,324,800
Therefore, the different batting orders they would have are: 60,949,324,800

Answer:
12x+36
Step-by-step explanation:
If we subtract 36 from all 4 y's we get 72, 144, 216, and 288. We divide each one by 6, 12, 18, and 24. After we divide them up, we get 12 for each one. Now we need to set the equation up, it has to be 12x because the price of just one T-shirt is $12, the x is how many T-shirts are bought. The 36 is the b-intercept of the equation, and since we write this in y=mx+b, the equation is y=12x+36.
A linear model will be 12x+36.

What is the volume of the toy top pictured below?
Answer:
The volume of the top toy is 67.1175 cubic feet
Step-by-step explanation:
The toy top is a composite figure of a cylinder and an hemisphere, the volume of the figure is therefore, the sum of the volume of the cylinder and the hemisphere
The dimensions of the cylinder are;
The height of the cylinder = 6 feet
The diameter of the cylinder, [tex]D_{cylinder}[/tex] = 1.5 feet
Therefore, the radius of the cylinder, [tex]r_{cylinder}[/tex]= 1/2 × [tex]D_{cylinder}[/tex] = 1/2 × 1.5 ft. = 0.75 ft.
The volume of the cylinder = Area of the base × Height = π × [tex]r_{cylinder}^2[/tex] × (The height of the cylinder)
Where;
π = 3.14
∴ The volume of the cylinder = 3.14 × (0.75 ft.)² × 6 ft.= 10.5975 ft.³
The dimensions of the hemisphere are;
The diameter of the hemisphere, [tex]D_{hemispher}[/tex] = 6 feet
Therefore, the radius of the hemisphere, [tex]r_{hemisphere}[/tex]= 1/2 × [tex]D_{hemispher}[/tex] = 1/2 × 6 ft. = 3 ft.
The volume of the hemisphere = 2/3×π×[tex]r_{hemisphere}^3[/tex]
∴ The volume of the hemisphere = 2/3 × 3.14 × (3 ft.)³ = 56.52 ft.³the
The volume of the top toy = The volume of the cylinder + The volume of the hemisphere
∴ The volume of the top toy = 10.5975 ft.³ + 56.52 ft.³ = 67.1175 ft.³.

You can actually draw both points in a graph to find out as it makes it easier to understand. Or you could think, if C has moved from (0,0) to (-2,3). It means it moves to the left of the x axis by 2, then moves up by 3 on the y axis.
So point P should move the same way. (-3, 4) move by -2 on the x axis would make it -5, and for y you go up 3 steps so 4+3=7 making P's final location (-5,7)
