A sign in a bakery gives these options:
15 cupcakes for $26
24 cupcakes for $42
40 cupcakes for $66
Find each unit price to the nearest cent, and show your reasoning.
Which option gives the lowest unit price?
Answer:
The lowest unit price would be last option
Step-by-step explanation:
We must divide the price by the amount of cupcakes we will be getting. Once we do that we'll get:
A. 1.77 cents
B. 1.75 cents
C. 1.65 cents
Hope this helped
Answer:
40 cupcakes for $66
Step-by-step explanation:
To find the unit price of something, dived the total amount by how may there are.
$26 divided by 15 cupcakes would be $1.7333333333, but if you round it up, it would be $1.74
$42 divided by 24 cupcakes would be $1.75
$66 divided by 40 cupcakes would be $1.65
A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?
36 feet
29 feet
24 feet
31 feet
Answer:
[tex] \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 [/tex]
therefore the answer is 24
The height of the tree is approximately 26 feet.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Let's denote the height of the tree with 'h'.
Then we can use the trigonometric ratio for cosine as follows:
cos(50°) = adjacent/hypotenuse
cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)
Now we can solve for 'h':
0.64 = 20/(h + 5)
0.64(h + 5) = 20
0.64h + 3.2 = 20
0.64h = 16.8
h = 26.25
So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.
Therefore,
The height of the tree is approximately 26 feet.

How does the scatter plot of a nonlinear association differ from that of a linear association?
Scatter Plots of a non-linear association represent points scattered all over the graphs as there is no association with them. On the other hand, a linear association represents dots placed in a more straight line that covers most of the dots on a graph. To sum it up, a nonlinear association is a bunch of random dots all over the place and a linear association is straight with no mess-ups (nothing).
