Answer:
5
Step-by-step explanation:
40 mins left! total time= 60 mins x 3 hours =180 mins. 180 divided by 9 is 20. 20 times 7 is 140. 180-140 equals 40. yay!
It’s either no solution or just false depending on the answer choices you have
solving steps:
5(5t+1)=25t-7
25t+5=25t-7
5= -7
which is not true
Answer:
The publisher must sell 4,632 books in order to break even(total sold equals production costs).
Step-by-step explanation:
So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.
So you set up an equation:
13.75x=$63,690
x=63690/13.75
x=4632
Answer:
480 in²
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c², where "a" and "b" are side lengths of a right triangle, and c is the hypotenuse of the right triangle. We are given a side length of 30 inches and a hypotenuse of 34 inches, which will be "a" and "c" respectively. Therefore, we can solve for b, the missing side length:
a²+b²=c²
30²+b²=34²
900+b²=1156
b²=256
b=16
Therefore, the missing side length is 16 inches, making the area of the triangle A=bh=(30)(16)=480 in².
