If there are 35 drum students out of 112 students, that means there are 77 other band students. So, the ratio of drummers to other musicians would be 35:77, or 5:11 when simplified.
Hope this helps!
= (4x^3y^4)/(-8xy^2)
simplify exponents by subtracting the denominator exponent from numerator exponent [x^(3-1)]
= (4x^3y^4)/(-8xy^2)
simplify -4/8 by 4 into numerator and denominator
= (-1x^2y^2)/2
= (-x^2y^2)/2
ANSWER: (-x^2y^2)/2
Hope this helps! :)
9 students in the class play in the school band.
30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3
In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.
You can also turn the percentage into a fraction, it's really up to preference.
30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
If you divide 600/ 45 mins you get the kilometers per minute which is 13.33. Then you multiply 13.33 times 30 mins and you get 399.9 or 400 kilometers
