Answer:
A.
1. 6/9
2. 6/3
3. 3/6
4. 9/6
5. 3/9
B.
1. 8/12
2. 3/7
3. 5/3
4. 12/15
5. 20/25
Step-by-step explanation:
You can turn a ratio from #:# into #/# so if the ratio was 3:9 the fraction form would be 3/9.
225000=200000(1.03^t)
9/8=1.03^t
ln(9/8)=tln(1.03)
t=ln(9/8)/ln(1.03)
t=3.98
t=4 years
Answer:
Part A is $21 and part B is $30.21
Answer:
no
Step-by-step explanation:
-7+x^2-3x = 9+x-10
-7+(-2)^2-3*(-2) 9+(-2)-10
-7+4+6 9-12
3 > -3
if we substitute -2 to x, answer is not equal
Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
