Rewrite the fractions as improper fractions:
1. −4 2/5 ÷ (−5)
= -22/5 ÷ −5/1
= -22/5 x -1/5
=22/25
2. −4 4/5÷4
= -24/5 ÷ 4/1
= -24/5 x 1/4
= -6/5
= -1 1/5
3. −2 1/8 ÷ 1 1/4
= -17/8 ÷ 5/4
= -17/8 x 4/5
= -68/40
= -17/10
=-1 7/10
4. −6 7/8 ÷ (−3 3/4)
= -55/8 ÷ -15/4
= -55/8 x -4/15
= 220/40
= 11/6
= 1 5/6
5. −8 3/4÷ 2 1/6
= -35/4 ÷ 13/6
= -35/4 x 6/13
= -210/52
= - 105/26
= -4 1/26
Answer: 65000$ worth of things
This is edited, because I got it backwards last time.
We need to make 2500, but she only makes 4% of whatever she sells.
That means the equation is
2500 = 0.04x
Now, we just need to divide both sides by 0.04 and we get 65000.
Sorry for the confusion.
Answer:
obtain from (a number) another which contains the first number a specified number of times.
(X+5)^2 = x^2 +10x + 25
the expression that is equivalent to
To multiply it we apply FOIL method
Multiply x with x+5 first and then we multiply 5 with x+5

Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.
