Answer:
D 16 cupcakes and 40 cookies
Step-by-step explanation:
I wrote an equation to solve for this
2.5x + x = 56
x represents cupcakes
3.5x = 56
x = 16
16 represents cupcakes.
16*2.5 = 40 (cookies)
Answer:
C.$0.15 I TOOK IT ON STUDY ISLAND
Step-by-step explanation:
First, you want to find an exact point on the graph. What I mean by this is you want to go somewhere on the graph where the line goes through an exact y and x value.
Second, you want to figure out where this x and y value are. Where the graph first goes through two points is at (20, 3).
Third, you want to figure out what the 20 and the 3 mean. 20 is the number of messages and 3 is the dollar amount.
Finally, to calculate the amount of money per message, you divide the dollar amount (3) by the number of messages (20). So, you have 3/20. After this, simplify 3/20 to get 0.15, or 15 cents per message.
You would use the Law of Sines here. First realize that if A and B equal 35 and 65 respectively, C=180-65-35=80°. Then from the Law of Sines:
b/sin65=15/sin80
b=15sin65/sin80
b≈13.8 units (to the nearest tenth of a unit)
So if 1 CM in the model is 200 CM in the actual, just 200 x 17 which is 3400cm
so in Meters it would be 34 m
