Answer:
percentage decrease,20%
Step-by-step explanation:
50_40 books=,10 bus
10|50 ×100%=20%
2 x
----- = ------
3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
ANSWER
y=(x+3)(x-1)(x-5)
EXPLANATION
The given polynomial has x-intercepts at x=-3,x=1,x=5
These are called the zeros of this polynomial.
We can use the factor theorem to obtain the polynomial in factored form.
The polynomial in factored form is of the form
y=a(x+3)(x-1)(x-5)
The polynomial rises on the left and keep rising on the right.
This implies that, the 'a' is positive.
Therefore
y=(x+3)(x-1)(x-5)
The correct choice is the first option.
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda <em>still</em> have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer/Step-by-step explanation:
Greg rent the car for 3 day so 3 x 24.95= $74.85 off the top without driving a single mile.
If he has a budget of $250, his remainder budget for mileage is $250 - $74.85 = $175.15.
How many miles he can travel at $0.28/mile with $175.15 budget?
Greg can drive $175.15/0.28 = 625.53 or 625 Miles
