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
![12 \times x + x = 117 \\ 13x = 117 \\ x = \frac{117}{13} \\ x = 9](https://tex.z-dn.net/?f=12%20%5Ctimes%20x%20%2B%20x%20%3D%20117%20%5C%5C%2013x%20%3D%20117%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B117%7D%7B13%7D%20%20%5C%5C%20x%20%3D%209)
Cara has 12×9 cards, so she has 108 cards.
Hope this was helpful :)
Hello!
The following numbers are greater than 0.7:

Answer:
exponential function, cool
Step-by-step explanation:
looks like f(x) = e ^x
So f(3) would be e^(3)
you can work this out on your calculator.
press [2ndf] [e^x]] [3] = 20
Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer
Answer:
19.8 and 8/(sin(theta))+ 6/(cos(theta))
Step-by-step explanation:
If you make a table you can see that L_1 + L_2 gets larger as you increase theta prom pi/2 and decrease theta from pi/2. This means that pi/2 is the theta that will yield the smallest length for the ladder. Plugging this into L_1 + L_2 you get 19.8 (rounded to the nearest hundred)
C = 8/(sin(theta))+ 6/(cos(theta))
