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

GIVING 100 POINTS FOR THIS QUESTION PLS PL SPL SPLS PLS HELPPP!!!!! !!
sergiy2304 [10]

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:

  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°.
