Answer:
y=-4x+7/2
Step-by-step explanation:
slope-intercept form follows the following format:
y=mx+b
simply replace m with -4 and b with 7/2
Answer:
It will take 146 days to earn an interest of $80.
Step-by-step explanation:
The simple interest formula is:

It is provided that:
I = $80
P = $4,000
r = 5% p.a.
Compute the time required as follows:



Thus, it will take 146 days to earn an interest of $80.
Answer:
total # of boxes sold = 90
Step-by-step explanation:
54 is 60% of total #
54 = .6x
x = 54/0.6 = 90
Answer:
5cm
Step-by-step explanation:
volume = πr²h
225π = π × r² × 9
225/9 = r²
r = √225/9 = 15/3 = 5cm
Answer:
1. 12/13 and 5/13
2. 5/13 and 12/13
3. The sin of <A and cos of <B are congruent.
Since "Sine" is Opposite/Hypotenuse and Cosine is adjacent hypotenuse...
The opposite of angle A is 12, and the hypotenuse is 12, therefore making 12/13.
The adjacent of angle B is 12, (The adjacent side is the side next to the opposite that is not the hypotenuse) and the hypotenuse is 13, therefore making 12/13. (The hypotenuse never changes no matter how you look at the triangle.)
Sin <A = 12/13
Cos <B= 12/13
