Answer:

37.5%

Step-by-step explanation:

This week, the cost is higher when we compare to last week. Therefore, the percentage difference is given by comparing the price differences to the price for the previous week.

Difference in costs=165-120=45

Percentage difference with respect to last week's price= \frac {45}{120}\times 100=37.5%

Therefore, percentage increase is 37.5%

5x−4 = 3x +8<br> i need the steps on how to find x<br> plz, i got a 0 the first time i did it
svetoff [14.1K]

Answer:

5x − 4 = 3x + 8

5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>

5x = 3x + 12

5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>

2x = 12

2x <em>/ 2</em> = 12 <em>/ 2</em>

x = 6

HELP!! I'm not sure what goes in the blank.
natta225 [31]

Answer:

10sin^{2} (β)

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10sin^{2} (β) on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10sin^{2} (β).

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10sin^{2} (β) cos(β)

But since cos(β) is already present, we can see that the answer is 10sin^{2} (β)

0.25q+0.10d=4.95<br> D=3q
lorasvet [3.4K]
0.25q + 0.1d = 4.95
d = 3q

0.25q + 0.1(3q) = 4.95
    0.25q + 0.3q = 4.95
               <u>0.55q</u> = <u>4.95</u>
                0.55     0.55
                      q = 9
0.25(9) + 0.1d = 4.95
    2.25 + 0.1d = 4.95
  <u>- 2.25             - 2.25</u>
               <u>0.1d</u> = <u>2.7</u>
                0.1     0.1
                    d = 27
