Answer:
$59.96
Step-by-step explanation:
Given:
The science club has raised $154. 24 to buy food for a polar bear cub at the zoo.
It costs $53.55 to feed the cub each week.
Question asked:
How much more money does the club need to raise to feed the cub for one month (four weeks)?
Solution:
Cost of feed for the cub for 1 week = $53.55
Cost of feed for the cub for 4 weeks = $53.55 
4 = $214.20
Money raised by the science club = $154. 24
More money needed by science club = Cost of feed for 4 weeks - Money raised by the science club
More money needed by science club = $214.20 - $154. 24
= $59.96
Thus, the science club will be needed $59.96 more money for one month (four weeks) feed.
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
Answer:
The possible rational roots are: +1, -1 ,+3, -3, +9, -9
Step-by-step explanation:
The Rational Root Theorem tells us that the possible rational roots of the polynomial are given by all possible quotients formed by factors of the constant term of the polynomial (usually listed as last when written in standard form), divided by possible factors of the polynomial's leading coefficient. And also that we need to consider both the positive and negative forms of such quotients.
So we start noticing that since the leading term of this polynomial is 
, the leading coefficient is "1", and therefore the list of factors for this is: +1, -1
On the other hand, the constant term of the polynomial is "9", and therefore its factors to consider are: +1, -1 ,+3, -3, +9, -9
Then the quotient of possible factors of the constant term, divided by possible factor of the leading coefficient gives us:
+1, -1 ,+3, -3, +9, -9
And therefore, this is the list of possible roots of the polynomial.
answer is 13 but I can't understand the question
I think there is no correct answer in this question!
you can solve this by analytic geometry rules easily!!
Answer:
4 (x + 7) = 8
Step-by-step explanation:
4 (x + 7) = 8 Because you add 7 to Amy's number then multiplied by 4 which equals 8
