Answer:
Cara:108
Step-by-step explanation:
John: x number of cards
Cara: 12 times x number of cards(she has 12 times more cards than John)
Cara+John=117 cards

Cara has 12×9 cards, so she has 108 cards.
Hope this was helpful :)
Answer:
- arc BF = 76°
- ∠M = 31°
- ∠BGE = 121°
- ∠MFB = 111°
Step-by-step explanation:
(a) ∠FBM is the complement of ∠FBC, so is ...
∠FBM = 90° -52° = 38°
The measure of arc BF is twice this angle, so is ...
arc BF = 2∠FBM = 2(38°)
arc BF = 76°
__
(b) ∠M is half the difference between the measures of arcs BE and BF, so is ...
∠M = (1/2)(138° -76°) = 62°/2
∠M = 31°
__
(c) arc FC is the supplement to arc BF, so has measure ...
arc FC = 180° -arc BF = 180° -76° = 104°
∠BGE is half the sum of arcs BE and FC, so is ...
∠BGE = (1/2)(arc BE +arc FC) = (138° +104°)/2
∠BGE = 121°
__
(d) ∠MFB is the remaining angle in ∆MFB, so has measure ...
∠MFB = 180° -∠M -∠FBM = 180° -31° -38°
∠MFB = 111°
Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
=
%
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
=
%
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,
Therefore, Option B and F is correct only.
The answer to this question is INTEGER
