Answer:
6.5 inch speakers for 17.99 is the better deal.
Step-by-step explanation:
Divide 17.99 by 6.5 to find the cost per inch for the 6.5 inch speakers, which is approx. 2.8 (rounded to the tenth).
Multiply 2.8 by 12 to get $33.60, which is obviously a better deal, as the 6.5 inch speakers are cheaper. Hope this helps.
The answer is no because after each 3 there is one more zero added
to be repeating the number of zeros would have to stay the same
Answer:
D: 5 : 8 and 20 : 32
Step-by-step explanation:
A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.
B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.
C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.
D is correct because 5 x 4 = 20 and 8 x 4 = 32.
another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....
Easy right!?

Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
Answer:
10
Step-by-step explanation:
3/5 = 15 dogs
divide 15 by 3 and get 5
so each 1/5 = 5 animals
4/5 = 20
5/5 = 25
25-15=10
