Answer:
2 : 3
Step-by-step explanation:
We need to convert minutes to seconds
1 minute = 60 seconds
2 minutes = 2*60 = 120 seconds
80 seconds : 120 seconds
Divide by 40
80/40 : 120/40
2 : 3
Answer:
See below
Step-by-step explanation:
population = 28400* ( 1+.05)^t t = years past 2000
8 years from 2000 pop = 28400(1.05)^8= 41 960 foxes
Answer:
x=1
Step-by-step explanation:
Substitute the value of y to the first given
3x+4(-x)=-1
3x+(-4x)=-1
-x=-1
divide both sides by -1
x=1
Answer:
22.1
Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1

Answer:
(a) cannot be determined
(b) 44 cm^2
(c) 87 m^2
(d) 180 m^2
(e) 132 m^2
Step-by-step explanation:
(a) missing a horizontal dimension
__
(b) The difference between the bounding rectangle and the lower-left cutout is ...
(8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2
__
(c) The difference between the bounding rectangle and the center cutout is ...
(13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2
__
(d) The difference between the bounding rectangle and the two cutouts is ...
(20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2
__
(e) The difference between the bounding rectangle and the two cutouts is ...
(14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2
