Answer:
Step-by-step explanation:
3+5+2=10
3/10 x 300=£90
3/10 x300=£150
2/10 x300=£60
Mary receives £150
Answer:
Dave gets £5
Explanation:
1 + 7 = 8
40 / 8 = 5
1 x 5 = 5
7 x 5 = 35
Answer:
the inverse is the third choice
AC+CE=AE
Pythagorean theorem is a big part of this problem. a^2+b^2=c^2
Part AC
8^2+6^2=c^2
64+36= 100
c^2 =
or
5^2 to match c^2.
Part CE
It is similar to the other one. It's just scaled. 6 to 8, 4 to....6
4^2+6^2=c^2
16+36=52
c^2 =
It is not a perfect square. So that will be the answer.
