Answer:
1) B
Step-by-step explanation:
1)
The formula for the volume of a prism is h * l * w
So, if we do that we get 25/18
2) B
Lets say we talk the top surface, there are 30 cubes on that surface and we want to find the volume of one cube so we are going to divide by 50. we take the measurements which are 5/6 and 1 for the top surface and we multiply. We get an answer of 5/6 now we divide by 30
So...
5/6 * 1/30 (We switched the numbers around because we are dividing.)
5/6 * 1/30 = 5/180 now we can simplify this to 1/36.
5 and 180 are a factor of 5
Hope this helps
Answer:
2/7
Step-by-step explanation:
-1 1/7 + 6/7 = -8/7 + 6/7 = 2/7
Answer:
26, 27, 28, 29
Step-by-step explanation:
Let the first integer be x.
Then, (x)+(x+1)+(x+2)+(x+3) = 110
=> x+x+1+x+2+x+3 = 110
=> 4x+6 = 110
=> 4x = 110-6
=> 4x = 104
=> x = 104/4
=> x = 26
So, the four consecutive integers are:
1. x = 26
2. x+1 = 26+1 = 27
3. x+2 = 26+2 = 28
4. x+3 = 26+3 = 29
R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)
= </span>$320 + <span>$360
= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
Answer:
Step-by-step explanation:
Let x represent the total number of stdents that has all grades in the school.
There are three grades in the school. One grade has 1/3 of the students, this means that number of students that belongs tho this grade is 1/3 × x = x/3
One grade has 1/4 of the students, this means that number of students that belongs to this grade is 1/4 × x = x/4
Total number of students in both grades would be x/3 +/x/4 = 7x/12
The number of students in the remaining grade would be
x - 7x/12 = 5x/12
fraction of students in the remaining grade would be
(5x/12)/x = 5/12
