Answer:
the length of the wall of the room = 11
Step-by-step explanation:
if it's a square room, area of each wall, floor and top are equal, so,
=》
=》
=》
so, length of wall of the room is 11 meters.
If you divide the cost by the ounces, that will be the unit rate.
3.60 divided by 12 is 0.3 or 30 cents. 5 divided by 20 is 0.25 or 25 cents. 6.40 divided by 32 is 0.20 or 20 cents
Out of 170 students in 12th grade, 27+23 = 50 students have more than 1 college in mind.
So 50/170, or 29% is your answer.
Answer:
23.5 cm
Step-by-step explanation:
The model distance x is proportional to the scale:
x/(47 ft) = 1 cm/(2 ft)
Multiplying by 47 ft gives ...
x = (1 cm)(47/2) = 23.5 cm
The distance from half-court on the model is 23.5 cm.

3x-2=A(x-1)+Bx
3x-2=x(A+B)-A
A+B=3
-A=-2=>A=2
A+B=3=>2+B=3=>B=1
lets check our partial fraction
we have
