Okay so first we need to find 40% of 7.50. To do this you simply divide the percentage by 100, so you have .4 now. You multiply 7.50 by .4 and get 3. Lastly, you just subtract 3 from 7.50 and you get $4.50

Emma will pay $4.50 after the discount.

Answer:

$28 . 26cm$

Step-by-step explanation:

First find the radius

$d = 2r \\ 9 = 2r \\ \frac{9}{2} = \frac{2r}{2} \\ r = 4.5$

Now find the CIRCUMFERENCE

$c = 2\pi \: r \\ = 2 \times \pi \times 4.5 \\ = 9 \times \pi \\ = 28.26$

Angle RZT=110<br> Angle RZS=3s<br> Angle TZS=8s<br> What are angles RZS and TZS?

nekit [7.7K]

Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:

110+3s+8s=180

Simplifying, we have:

11s=70

Dividing by 11, we see that:

s=70/11

Therefore, RZS=3s=210/11, and TZS=8s=560/11.
