Work done= 10 10 ft-lbs.
This prism has a right triangle for a base. What is the volume of the prism?
length = 6 x 1/3 = 2 inches
width = 4 x 1/3 = 4/3 inches
height = 8 x 1/3 = 8/3 inches
volume = lwh = 2 x 4/3 x 8/3 = 64/9 cubic inches
Another approach is the following:
There are 6 x 4 x 8 = 192 cubes inside the prism,.
Each cube has a volume of 1/27 cubic inches.
Therefore total volume = 192 x 1/27 = 192/27 = 64/9

The expression 6k is an algebraic expression where 6 is the number of dollars Andrew earns per hour doing odd jobs and k is the number of hours he works. What expression describes the number of hours Andrew worked if he earned $30.00?
Answer: 30 = 6(5) thirty equals six times five.
Step-by-step explanation: Divide the total money earned by the pay Andrew gets for every hour to find how many hours Andrew worked to get that amount of money.
$30.00 = 6k

There are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Write the ratio of boys to girls in lowest terms.
Given that : There are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Need to find : the ratio of boys to girls in lowest terms.
Firstly we need to find out the number of boys . For that subtract the number of teachers and girls from total number of teachers and students. That will be ,
[tex]\implies \sf n( boys) = 76 - 4 - 40 =\red{ 32 }[/tex]
Therefore our required ratio will be:-
[tex]\implies \sf 32 : 40 = \boxed{\sf 4:5 }[/tex]
Hence the required answer is 4:5 .

The number of coloured papers as per the given problem is 18.
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
Given that,
The ratio of coloured papers to white papers is 3/8.
And, the number of white papers is 48.
Suppose, the number of coloured papers be x.
Then, as per the question the following equation can be obtained,
3/8 = x/48
=> x = 3/8 × 48
=> x = 18
Hence, the number of coloured papers is 18.

Solve for x.
x = [?]
X - 6
8x + 24
Answer:
x=18
Step-by-step explanation:
Both angles are supplementary angles and form 180
Set your formula up as following
(x-6) + (8x+24) = 180
x+8x-6+24=180
9x=180+6-24
9x=162
x=162/9
x=18
Now substitute 18 for x to get your angles and check your work .

I REALLY NEED HELP PLS HELP ME ON THIS MATH
Answer:
Ok, we can define a function as a relation that maps elements from a set (the domain) into elements from another set (the range), such that each element in the domain can be mapped into only one element of the range.
2) Here you choose the autographed poster, and we know that each one of these costs $10.
So, if the artist sold x posters, then he/she would earn x times $10:
earnings = $10*x
So we can create a function:
f(x)
such that f(x) represents the total earnings of the artist for selling x posters.
And we already know the equation for the earnings, so the function will be:
f(x) = $10*x
3) Now, it asks us if the values:
-2, -1, 0, and 1
be appropiate for the domain of the function.
Remember that x represents the number of posters that the artist sold.
Then, if we take x = -2 or x = -1 (like the first two given values) this would mean that the artist sold a negative number of posters, which has no real sense in the situation given. So we can conclude that these values should not be in the domain of the function.
For the other two cases, 0 and 1, these two can be in the domain, because these represent the case where the artist sold only one poster and the case where the artist did not sell any poster (that are two possible cases)

If the probability that a student in school wears contacts is 0.38 and the probability that a student in the same school has a car is 0.42, what is the probability that a student wears contacts and has a car?
Answer:
Probability [Student wears contacts and has a car] = 0.1596
Step-by-step explanation:
Given:
Probability [Student in school wears contacts] = 0.38
Probability [Student in the same school has a car] = 0.42
Find:
Probability [Student wears contacts and has a car]
Computation:
P[A and B] = P(A) × P(B)
So,
Probability [Student wears contacts and has a car] = Probability [Student in school wears contacts] x Probability [Student in the same school has a car]
Probability [Student wears contacts and has a car] = 0.38 x 0.42
Probability [Student wears contacts and has a car] = 0.1596
A survey of 125 freshmen business students at a local university produced the results listed below. How many students took history and math, but not music? 30 took history; 32 took math; 33 took music; 14 took history but not math; 9 took math and music; 13 took history and music; 2 took all three
Answer:
Total Number of students taking Math and History and not music are 68.
Number of students who took both math and history at the same time is 6.
Step-by-step explanation:
History = 30
Math = 32
Music= 33
Math and Music= 9
History and Music= 13
History and Music and Math = 2
History but not math = 14
We have to find students taking history and math but not music.
Total number of students = 125
From the figure number of students taking Math and History and not music are
=30+6+32= 68
Number of students who took both math and history at the same time is 6.
In the question, "35 is what percent of 40?" what is the 35?
Answer:
35 is the 'is' and 40 is the 'of'
Step-by-step explanation:
is/of = %/100
35/40 = x/100
cross-multiply to get:
40x = 3500
x = 3500/40
x = 87.5
