*Note that I'm assuming the prism is a triangular prism
Volume = 60cm³
Height = 6cm
Width = 2cm
The equation for the volume of a triangular prism is:
V = [tex]\frac{b * h * l}{2}[/tex]
Let's substitute in the values we already know:
60 = [tex]\frac{2 * 6 * l}{2}[/tex]
And now we need to make l the subject by multiplying both sides by 2:
120 = 2 x 6 x L
Simplify:
120 = 12L
Flip to make easier to read:
12L = 120
Divide both sides by 12 to get the value of L (length):
L = 10
And let's show proof that L = 10 (remember that V (volume) should be equal to 60):
V = [tex]\frac{2 * 6 * 10}{2}[/tex]
V = [tex]\frac{120}{2}[/tex]
V = 60
Therefore we can determine the the length is indeed 10cm.
I hope this helped! :)

Joseph needs 345 cement blocks to build a wall 40 cm thick. He needs 205 cement blocks to build a wall 25 cm thick. Each block costs $0.75. How much more will the thicker wall cost?
9514 1404 393
Answer:
$105
Step-by-step explanation:
The thicker wall takes 345 -205 = 140 more blocks. Each of those costs $0.75, so the added blocks will cost ...
140 × $0.75 = $105
The thicker wall will cost $105 more.
A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x - 1) where x is the number of hours. What is the
function that shows total sales, including the first hour? (1 point)
s(x) = 15(x - 1) - 120
s(x) = 120x - 15
Os(x) = 120 + 15(x - 1)
Os(x) = 120 - 15(x - 1)
Answer:
X=104
Step-by-step:
Sorry IF my answer is wrong
Answer:
Os(x) = 120 + 15(x - 1)
Step-by-step explanation:
The total sales will be the sum of the constant 120 copies that were sold in the first hour and the sales in the subsequent hours, represented by the function s(x) = 15(x-1).
Thus, add 120 to the function s(x).

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?
Answer:
3miles per hour^2
Step-by-step explanation:
given data
initial speed u= 15mph
final speed v=45mph
time taken t= 10 seconds
Step two:
Required
acceleration a=?
applying the first equation of motion
v=u+at
substitute we have
45=15+a*10
45=15+10a
make a subject of the formula
45-15=10a
30=10a
divide both sides by 10
a=30/10
a=3miles per hour^2

Joe creates a new email account. In October he receives 120 emails and in November he receives 177 emails. Joe says the percent change from October to November
is calculated by taking the ratio of the difference between the number of emails received in November and October to the number of emails received in November
Therefore, he says, the percent change, rounded to the nearest whole percent is 32%. Is he correct?

Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.
Answer:
a) is wrong because a number gets smaller, not larger, when you take 4.2 from it
Step-by-step explanation:
Given
[tex]5 - 4.2 = 8[/tex]
Required
Determine which of the options is true
First, we need to solve for 5 - 4.2
[tex]5 - 4.2 = 0.8[/tex]
Compare this answer with Terell's answer (8)
We observe that: [tex]0.8 \neq 8[/tex]
This implies that; Terell is wrong
The two options that support the answer being wrong are (a) & (d)
Analyzing (a):
5 should get smaller when 4.2 is subtracted from it.
This isn't the case in Terell's solution.
Hence, (a) is true
Analyzing (d):
d is wrong because a decimal can be subtracted from a whole number
Hence, (a) answers the question

What is the slope of a line that is perpendicular to the graphed line?
Answer:
The slope of the line perpendicular to the graphed line is 2.
Step-by-step explanation:
The Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The graphed line passes through two visible points (0,4) and (8,0). Thus, its slope is:
[tex]\displaystyle m=\frac{0-4}{8-0}[/tex]
[tex]\displaystyle m=\frac{-4}{8}[/tex]
Simplifying:
[tex]\displaystyle m=-\frac{1}{2}[/tex]
Two lines of slopes m1 and m2 are perpendicular is:
[tex]m_1.m_2=-1[/tex]
Suposse the given line has slope [tex]m_1=-\frac{1}{2}[/tex]. To find m2, we solve the above equation:
[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]
Substituting:
[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{2}}[/tex]
Operating
[tex]m_2=2[/tex]
The slope of the line perpendicular to the graphed line is 2.

write 62/15 as a mixed number.
Answer:
4 & 2/15Step-by-step explanation:
Answer:
[tex]4\frac{2}{15}[/tex]
Step-by-step explanation:
A mixed number is a number that contains an integer with a proper fraction eg: [tex]1\frac{1}{2}[/tex]. The fraction that is given is improper and can be turned into a mixed number to simplify it.
First, we need to find how many times 15 goes into 62:
62÷15 = 4r2
This can then be written as the mixed fraction: [tex]4\frac{2}{15}[/tex].

Step-by-step explanation:
Select all the ordered pairs that make this statement true?
3x + 4y = 36
(3,-2)
(1,7)
(0,0)
(24,-9)
(0,9)
(4,6)
(-12,18)
Answer: (24,-9)
(0,9)
(4,6)
Step-by-step explanation:
3x + 4y = 36
Using (3,-2) will be:
= 3(3) + 4(-2)
= 9 - 8 = 1
Using (1,7) will be
= 3(1) + 4(7)
= 3 + 28 = 31
Using (0,0) equals to 0
Using (24,-9) will be:
= 3(24) +4( -9)
= 72 - 36 = 36
Using (0,9) will be:
= 3(0) + 4(9)
= 0 + 36 = 36
Using (4,6) will be:
3(4) + 4(6)
= 12 + 24
= 36
Using (-12,18) will be:
= 3(-12) + 4(-18)
= -36 - 72
= -108
The correct options are (24,-9), (0,9 and (4,6)
whats 100x100x100 idk wht it is
Answer:
100,000,0
Step-by-step explanation
To solve this problem you need to start with 100, since 100 has 2 zero's you want to add 2 zero's 2 times in a row, like this-- 100+00=10,000+00=100,000,0.
Thus your answer: 100,000,0
Convert the following into slope-intercept form. 3x+4y=-16
Answer:
y = -3/4x -4
Step-by-step explanation:
3x+4y=-16
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+4y=-3x-16
4y = -3x-16
Divide each side by 4
4y/4 = -3x/4 - 16/4
y = -3/4x -4
Answer:
y= -3/4x - 4
Step-by-step explanation:
3x+4y=-16
4y= -3x-16
y= -3/4x -4
