A rectangle's area formula is Length x Width.
24/6 = 4
The length is 4 ft.
<h3>Given</h3>
–5x3y3 + 8x4y2 – xy5 – 2x2y4 + 8x6 + 3x2y4 – 6xy5
<h3>Find</h3>
Which of the following represents the expression written in standard form:
–7xy5 + 5x2y4 – 5x3y3 + 8x4y2 + 8x6
5xy5 + 8x4y2 + x2y4 – 5x3y3 + 8x6
8x6 + 5xy5 + 8x4y2 + x2y4 – 5x3y3
8x6 + 8x4y2 – 5x3y3 + x2y4 – 7xy5
<h3>Solution</h3>
The variables are x and y. All terms have degree 6, so we can choose to write them in order of decreasing powers of x or of decreasing powers of y.
The terms tha can be combined are those involving xy⁵ and x²y⁴. Combining those terms, we have xy⁵(-1-6) = -7xy⁵, and x²y⁴(-2+3) = x²y⁴.
The first offered choice has the powers of y in decreasing order, but it has an incorrect coefficient for x²y⁴. The second and third offered choices have no consistent ordering of powers.
The best choice is the last one:
... 8x⁶ +8x⁴y² -5x³y³ +x²y⁴ -7xy⁵
0.326
to get percent, move the decimal point over two spaces to the right:
32.6%
to get fraction, put it over 100 by moving the decimal spaces two to the right:
32.6/100
To get a fraction that is not include a decimal, write it over 1000 (at this case:
326/1000
hope this helps
Answer:
The correct answer is option B
Step-by-step explanation:
The general form of inverse variation between the variables x and y is as following:
where c is constant
option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (correct option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12x (wrong option)
So, the correct option is B
Answer:
7 : 210
Step-by-step explanation:
ratio of teachers : students
= 210 : 3300 ← divide both parts by 30
= 7 : 210
