Step-by-step explanation:
a) Desiree is correct 630000÷70=900
180 - 53 - 96 = 31°. you know the angles are 53 and 96 degrees because the triangles are congruent via SAS congruency.
S.F. of 9/24 = 3/8
S.F. of 14/24 = 7/12
S.F. of 10/15 = 2/3
S.F. of 10/12 = 5/6
S.F. of 18/27 = 2/3
S.F. of 10/15 = 2/3
Hope this helps!
For calculating that, you have to find the unit rate first;
2.4 pound carrot = $1.68
1 pound carrot = $1.68/2.4 = $0.7
1.8 pound broccoli = $1.53
1 pound broccoli = $1.53/1.8 = $0.85
So, it would be = $0.85 - $0.7 = $0.15
SO, YOUR ANSWER IS $0.15
No. they change because you are changing the size of the shape
