A cuboid has 4 rectangular faces and 2 square faces. Each rectangular face measures 8 cm by 6 cm. Find the two possible values for the surface area of the cuboid.
pls give me answer with steps
Answer:
320 cm² or 264 cm²
Step-by-step explanation:
first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²
the 2 square faces will be either 8 x 8 or 6 x 6.
If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²
If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²

IM SICK OF ALL THE FAKE LINKS! Can I get help?
Answer:
equation: 28 = 2h+ h + h or you could say 28 = 4h
h= 7
Step-by-step explanation:
since both lines are the same length they equal each other.
to get h = 7 you have to solve the equation you made.
28 = 4h
28/4 = 4h/4
7 = h

Instead of dividing $15.00 by 2 1/2, double both numbers and then find the quotient.
Answer:
6
Step-by-step explanation:
the mean of "n" numbers is "x" . if one more is added the mean is "y" . write an algebraic expression for the value of the number added?
Answer:
yn +y -xn
Step-by-step explanation:
Mean= sum of numbers ÷number of numbers
x= sum of n numbers ÷n
Multiply both sides by n:
xn= sum of n numbers
sum of n numbers= xn -----(1)
Let the number added be a.
After a has been added,
y= (sum of n numbers +a) ÷(n+1)
Multiply both sides by (n +1):
y(n +1)= sum of n numbers +a
sum of n numbers= y(n +1) -a -----(2)
Substitute (1) into (2):
xn= y(n +1) -a
Expand:
xn= yn +y -a
a= yn +y -xn
Let's check!
Let the numbers be 1, 2, 3 and 4.
mean, x= 10 ÷4= 2.5
n= 4
Let the new number added, a, be 7.
a= 7
mean, y= 17 ÷5= 3.4
a= yn +y -xn
a= 3.4(4) +3.4 -2.5(4)
a= 7
Thus, the expression is true.
Perpendicular to x+y=6 and passing through (0,1)
Answer:
y = x + 1
Step-by-step explanation:
x + y = 6
y = -x + 6
Perpendicular slope to -1 is 1
(0,1)
y - y1 = m(x - x1)
y - 1 = 1(x - 0)
y - 1 = x
y = x + 1
Standard form:
y = x + 1
-x + y = 1

Does anyone know what 9x*3x/4 is?
Answer and Step-by-step explanation:
We are given the expression [tex]\frac{9x * 3x}{4}[/tex].
First, we need to multiply 9x by 3x. This results us with [tex]27x^2[/tex].
[tex]\frac{27x^2}{4}[/tex] -- This is the final expression simplified. There isn't anything else we can do this expression, as it is not factorable and can't be simplified any further.

The points plotted below are on the graph of a polynomial. How many roots
of the polynomial lie between x = -4 and x = 3?
URGENT
Given:
The graph of a polynomial.
To find:
The number of roots of the polynomial lie between x = -4 and x = 3.
Solution:
From the given graph it is clear that the graph is a downward U-shaped curve. It means the given graph represents a quadratic polynomial.
The graph of the polynomial is below the x-axis immediate before x=-2 and above the x-axis immediate after x=-2. It means the graph intersect the x-axis at x=-2.
The graph of the polynomial is above the x-axis immediate before x=2 and below the x-axis immediate after x=2. It means the graph intersect the x-axis at x=2.
Since the graph of the polynomial divides the x-axis two times between x = -4 and x = 3, therefore the two roots of the polynomial lie between x = -4 and x = 3.
If using the method of completing the square to solve the quadratic equation

what is the mean,median,mode ,and range of 24,12,10,15,10,22,12
Answer:
24, 12, 10, 15, 10, 22, 12
mean: 7
median: 12
mode: 12
Range: 14
Step-by-step explanation:
Answer: Mean=15, Median=12, Mode=10 and 12, Range=14
Step-by-step explanation:
Data:
Numbers: 10, 10, 12, 12, 15, 22, 24
Mean: x, Median: x, Mode: x, Range: x
Step One, Find the Mean by adding all of the numbers and dividing them by the number of numbers
10+10+12+12+15+22+24=105/7=15
Mean=15
Reason: By adding all of the numbers together and dividing them by the number of numbers, you can find the mean because that is the method on finding the mean.
Step Two, Find the Median(middle) by finding the number in the middle
10, 10, 12, 12, 15, 22, 24
Median=12
Reason: Since the median is the number in the middle, 12 would be the median since it is the number in the middle of the array of numbers.
Step Three, Find the mode by finding the number that show up the most
10, 10, 12, 12, 15, 22, 24
Mode=10 and 12
Reason: Since mode is finding the number that shows up the most, 10 and 12 would be the answer for that reason and that they show up the same number of times in the array of numbers.
Step Four, Find the range by subtracting the biggest number by the smallest
24-10=14
Reason: Since to find the range you have to subtract the biggest number(24) by the smallest(10) the answer has to be 14 because that us the answer to 24-10.

Which expression is equivalent to the expression for the perimeter of the larger garden. Select all the apply.
Answer:
Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden
Step-by-step explanation:
The complete question is
A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.
4x+40 2(2x+20) 2(x+15)(x+5) 4(x+15)(x+5) 2(x+15)+2(x+5)Solution
The expression for the perimeter of the larger garden: [tex](x+15)+(x+5)+(x+15)+(x+5)[/tex]
If the given expression is expanded and solved, we get the following
[tex](x+15)+(x+5)+(x+15)+(x+5)\\X+X+X+X + 15+15+5+5\\2X+2X+30+10\\4X +40[/tex]
Hence, option A is correct
Reuben made $247 for 13 ours of work.

(A) A controlled experiment.
(B) An uncontrolled experiment.
(C) A double blind experiment.
Ablocked design experiment.
Answer:
(B) An uncontrolled experiment.
Step-by-step explanation:
In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled
Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the cholesterol level is decreased after particular time period,
Hence, it is an uncontrolled experiment.
Thus, option B is correct.

B
mDB = [?]°
Answer:
124°
Step-by-step explanation:
measure of arc DC = 44 because the measure of central angle equals the measure of its arc.
measure of arc CB = 80 because the measure of central angle equals the measure of its arc.
measure of arc DC = measure of arc DC + measure of arc CB
= 44 + 80 = 124°

The angles in a triangle are in the ratio 1 : 2 : 3
Show that the triangle is a right-angled triangle
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The angles in the triangle are 30°, 60°, 90°
Then the triangle is right angled
Answer:
The angles are 30°, 60° and 90°.Step-by-step explanation:
Hint : sum of the angles in triangle = 180°.The triangle is a right-angled triangle.Answer:Let missing angles be [tex]x[/tex], [tex]2x[/tex].
As the triangle is right-angled triangle.
[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]
[tex]3x = {180}^{o} - {90}^{o} [/tex]
[tex]3x = {90}^{o} [/tex]
[tex]x = \frac{90 ^{o} }{3} [/tex][tex]x = {30}^{o} [/tex]
[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]
Check:30° + 60° + 90° = 180°.Hope it is helpful....If a pumpkin weighs 2.7 kilograms and 1 pound is about 0.45 kilograms, how many pounds does the pumpkin weigh?
