Answer:
A = 15x^2 +11x+4
Step-by-step explanation:
can we assume you want the area...
A = 1/2 (B1+B2) h
A = 1/2(10x +4)(3x+2)
A= 1/2(30x^2 +22x+8)
A = 15x^2 +11x+4
Hey there!
When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.
If the small school had 60% boys, it will have 40% girls. The number of boys <em>is</em> 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.
0.6t=48
We divide both sides by 0.6.
t=80
Therefore, there are 80 total kids at the school.
We can also check our answer below.
BOYS: 0.6(80)= 48
GIRLS: 0.4(80)=32
48+32=80
I hope that this helps!
Answer:
-1 
, -1.75, 3/11, 0.3
Step-by-step explanation:
Negatives are always less then positive, so they would go first since its least to greatest.
7/9 = 0.77 which means -1 7/9 = -1.77, therefore it is less then -1.75
-1.75 would be next
3/11 = 0.2 which is less then 0.3 so it would go next.
and at last, goes 0.3 as the greatest number.
If the last day is y. and then the answer will be y=120-x
