Answer:
one 40% discount
Step-by-step explanation:
lets use 100$ total for an example.
Say we have 40% of 100 so the total would be 60$ but it we have 20% and then another 20% off that we would have a final total of 64$\
Prove: 100*.4=40 100-40=60
100*.2=20 100-20=80, 80*.2=16 80-16= 64$
Answer:
Surface Area= 498 cm²
Step-by-step explanation:
To calculate the surface area of this composite shape, work out the area of each face and add them together (break this composite figure into two shapes)
- Calculate the areas of the different sized faces
7 x 7 = 49
12 x 7 = 84
12 x 7 = 84
- Now, multiply these areas be number of corresponding faces
49 x 2 = 98
84 x 2 = 168
84 x 2 = 168
- Add these areas together
98 + 168 + 168 = 434
Now do the same for the shape above it
2 x 2 = 4 → 4 x 2 = 8
2 x 7 = 14 → 14 x 2 = 28
7 x 2 = 14 → 14 x 2 = 28 = 64
Add the surface areas together : 434 + 64 = 498 cm²

Answer:
-5
Step-by-step explanation:
Let's call this unknown number x.
Then (x+15)-8=2. Therefore, x=2+8-15 = -5.
Answer:
A = (5s^2t - 9st) (3t + 1)
Step-by-step explanation:
(5s^2 - 9s) (3t^2 + t)
= 15s2t^2 + 5s^2t - 27st^2 - 9st
= 5s2t (3t + 1) - 9st (3t + 1)
= ( 5s^2t - 9st) (3t+1)
