The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2

An experiment consists of rolling a number cube (dice). What is the probability of rolling a number GREATER THAN 4? Express your answer as a fraction in the simplest form.
Answer:
1/3
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur
Probability = Expected/Total outcome
Since the experiment requires rolling a dice
S = {1, 2, 3, 4, 5, 6}
Total outcome n(S) = 6
Number greater than 4 are;
Events E = {5,6}
Expected outcome n(E) = 2
Probability of rolling a number greater then 4 = 2/6
Probability of rolling a number greater then 4 = 1/3

Answer:
red = 28 apples
green = 13 apples
equations:
r + g = 41
r = g + 15
Step-by-step explanation:
r = number of red
g = number of green
r = g + 15 (the number of red apples is 15 more than the number of green apples)
r + g = 41
Substitute the firs equation into the second and solve for a numerical value of g
(g + 15) + g = 41
2g + 15 = 41
2g = 26
g = 13
Now solve for a numerical value of r
r = g + 15
r = 13 + 15
r = 28
checking the math:
r + g = 41
28 + 13 = 41

Volume without holes = 3 x 6 x 11 = 198 cubic inches.
Calculate volume of one hole:
3.14 x 0.5^2 x 3 = 2.355 cubic inches
There are 3 holes: 3 x 2.355 = 7.065
Subtract volume of the holes from the brick:
198 - 7.065 = 190.935 cubic inches.
Rounded to the nearest tenth: 190.9 cubic inches.
Answer:
190.9 inches^3
Step-by-step explanation:
First of all we have to find the total volume:
V = dimension 1 x dimension 2 x dimension 3
V = 3 x 6 x 11 = 198 inches^3
now we have to find the volume of the cylinders:
V= radius^2 x pi x height = 0.5^2 x 3.14 x 3 = 2.355 inches^3
the cylinders are three so:
V = 2.355 x 3 = 7.065 inches^3
at least we have to subtract this value at the total volume:
V= 198 - 7.065 = 190.935 = 190.9 inches^3

Find the distance between the two points in simplest radical form.
(-5,6) and (-3,-1)
Answer:
√53
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = -5
x2 = -3
y1 = 6
y2 = - 1
Solution
d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )
d = sqrt( ( -3 + 5)^2 + (-7)^2 )
d = sqrt( 2^2 + 49)
d = sqrt(4 + 49)
d = sqrt(53)

Two trains are 1.5 miles apart, train a is traveling at 3/4 the speed of train b if they meet in 4 minutes how fast is each train going
Answer:
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.
Step-by-step explanation:
Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have the following kinematic equations:
Train A
[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)
Train B
[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)
If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:
[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]
[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]
[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]
[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]
[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]
Then, the speed of the train B is:
[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.

10(x - 5) = -80 find the value of
Answer:
the value of x = -3
Step-by-step explanation:
10 (x-5) = -80
10x - 50 = -80
10x = -30
x = -3
CHECK:
10 ( -3 - 5) = -80
10 (-8) = -80
-80 = -80
Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2

а. .
y = -x-4
C.
y=x+4
by=-x+4
d. y = x-4
Answer:
y = -x + 4
Step-by-step explanation:
Mathematically, the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from the plot, the y intercept is 4
So we have;
y = mx + 4
To get the value of m, we substitute the coordinates of any point and solve for m
we select the point; (4,0)
so;
0 = m(4) + 4
4m = 0-4
4m = -4
m = -1
so the equation of the line is;
y = -x + 4
