Help please... dont answer if u dont know bc this is for a grade

1/3 and t/9

there are 3 trombones in the orchestra

Step-by-step explanation: it says the ratio of trombones to violas is 1/3 so that’s ur first one and it says there’s 9 violas so there’s ur 2nd one. 9 divided by 3 is 3 so you would multiply 1 by 3 and the answer is 3, making it 3 trombones in the orchestra

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
