Take 15% of 400, or 0.15 x 400
0.15 x 400 = 60
However, $60 is only the 15%.
Now, take away 60 from 400.
400 - 60 = 340.
So $340 went towards the trip.
Answer:
± 13
Step-by-step explanation:
= ± 13, since
13 × 13 = 169 and - 13 × - 13 = 169
23x25 is the same as 46x50 because you just multiplied both by two
Answer:
Insert non-suspicious whistling
Answer:
Step-by-step explanation:
1.
19² = 17² +x²
19² - 17² = x²
√361-289 =x
√72 = 8.5 ≈ x
Area = base*h/2 = 17*8.5/2 ≈ 72.3
Perimeter = 19+17+8.5= 44.5
and so on...
2.
x²= 5² +13²...
A= 5*13/2 =...
P= 5+13+x=...
3.
20² = 10² +x²...
A=10*x/2=...
P=20+10+x=...
4.
x² = 5² +14²...
A=5*14/2 =...
P= 5+14+x = ...
