Answer:
8587 should be in the box
Step-by-step explanation:
we would see it question as: 12/- 8587
12 goes into 85 7 times, so 7
12 goes into 18 1 time, so 1
12 goes into 67 5 times, so 5
then the remainder is 7
or you further divide to get . 5 8 3333333...
so your answer should be 715r7 or 715.58333
Answer:
C=$50+$75×T
Step-by-step explanation:
$50 is the amount charged to record an album + 75 amount charged per hour ×T which is how much hours you are going to record an audio.
Step-by-step explanation:
a^2 + b^2 = c^2
(x+2)^2 + 4x^2 = (3x+4)^2
(x+2)(x+2)+ 4x^2= (3x+4)(3x+4)
x^2 + 2x + 2x + 4 + 4x^2 = 9x^2 + 12x + 12 x + 16
5x^2 + 4x + 4 = 9x^2 + 24x + 16
-4x^2 - 20x - 12 = 0
now we can use the quadratic formula
(-b±√(b²-4ac))/(2a)
I can't type all this so
.....
x = -0.697224362 or -4.302775638
AB can't be negative so it's the first one
so it's equals to 1.302775638
The correct answer should be 20% because u were 80% certain he would remember so that means ur 20% certain he would forget
