The volume of a pyramid is 1/3 the volume of the cube mentioned in the question since it fits exactly inside it. So multiply 49*3 = 147 cubic feet
Set up a proportion of acres to days. 1/2 acre is to 4 days as 2 3/4 acres is to x days.
x= # days to clear 2 3/4 acres
2 3/4 to improper fraction= 11/4
(1/2)/4 = (11/4)/x
cross multiply
(1/2 * x) = (4 * 11/4)
on the right, the 4 "cancels out"
1/2x= 11
divide both sides by 1/2
x= 11 ÷ 1/2
to divide fractions, multiply by reciprocal/inverse of 1/2
x= 11 * 2/1
x= 22 days
ANSWER: It would take 22 days to clear 2 3/4 acres.
Hope this helps! :)
-3 + 8 is also the same as the expression mentioned above.
We can have the basic inequalities and equalities’ sign. (>, =, <).
These three set of symbols can discern, describe and explain the relationship between of numbers. These signs are used varying in many mathematical operations to explain and find discrepancy between value, sets of values or numbers in single and equitable category.
Examples includes
6 > 5; 6 is greater than 5; 5 is less than 6
1 > -1; -1 is less than 1; 1 is greater than -1
<span>-2 = -2; -2 is equal to -2 <span> </span></span>
