You would have 90 cause the tank is full then you would subtract that from 2x because 2 gallons drain per minute so your answer is 90-2x
Answer:
-225
Step-by-step explanation:
6*9*(-5)
45*(-5)
-225
when you multiply a negative number by a positive number its negative or if its positive by positive then its positive.
We are given function f(a) = 1.07a for total amount including sales tax.
g(b) = b+50 total cost including delivery.
We need to write function g(f(a)).
g(f(a)) = g of f(a).
We need to substitute function f(a) in g(b) function for b.
g(f(a)) = g(1.07a) = 1.07a +50.
<h3>Therefore, g(f(a)) = 1.07a +50.</h3>
We are given mattress price a = $1125.
In order to find the total cost including delivery charges, we need to plug a= 1125 in the above function 1.07a +50.
Plugging a= $1125, we get
g(1125) = 1.07a +50 = 1.07*1125 +50 = 1203.75 +50 = 1253.75.
<h3>Therefore, total cost including delivery charges is $1253.75.</h3>
(99(82)+99)/100 is the later mean of scores= 82.17
And the current mean of 82
82.17-82= 0.17 is the difference between the mean scores
The square root of 78 is Irrational
