Suppose he took 60 shots during his second season. How many shots would you expect
Quinnel to make during his second season of basketball?
Answer:
21
Step-by-step explanation:
his ratio of shots from the first game would be 14:40 or 7:20
so if he made the same ratio from 60 shots it would be
21:60
Which statement is true about the slope of the line and what it means in this
situation?
The slope of the line is 1. This means that Jan runs 1 lap every minute.
The slope of the line is 2. This means that Jan runs 2 laps every minute.
I
The slope of the line is 2. This means that Jan runs 1 lap every 2 minutes.
The slope of the line is 4. This means that Jan runs 4 laps every minute.
Answer:
B. The slope of the line is 2. This means that Jan runs 2 laps every minute.Step-by-step explanation:
This is a proportional relationship as the line passes through the origin.
Therefore you can use one point to determine the slope, (2, 4):
m = y/x = 4/2 = 2The slope is 2. It is a 2 laps per minute.
Correct answer choice is B
Slope
m=4-0/2-0m=4/2 m=2Rate is 2 laps every minute

Triangle UVW is dilated by a scale factor of 3 to form triangle UVW. Side VW
measures 54. What is the measure of side VW?
Answer:
162
Step-by-step explanation:
In geometry, dialation is increasing the size of a shape on a plane. Since the porblem you have givine isn't requiring the triangle to be centered around a point, this is fairly easy. If you are increasing UVW by a scale factor of 3, you are multiplying each side by 3. So, if side VW is 54, after dilation VW' will have a length of 162. (54 × 3 = 162)

Bob sees a very tall white pine tree. He estimates that the angle of elevation from him to the top of the tree is 77°
. He is 20 feet from the base of the tree when he measures the angle. What is the height of the tree rounded to the nearest hundredth?
Answer:
86.63 ft
Step-by-step explanation:
The tangent relation applies.
Tan = Opposite/Adjacent
tan(77°) = (tree height)/(20 ft)
tree height = (20 ft)·tan(77°) ≈ 86.63 ft
_____
Additional comment
It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.

Karen stacks a set of cans as shown. The top can has a diameter of 2 inches, the middle can has a diameter of 5 inches, and the bottom can has a diameter of 6 inches.
please help me
Answer:
B and E are the only correct answers.
Step-by-step explanation:
The top can's diameter is 2 inches, so the radius is 1. First find the area of the circular end, pi * r^2, 3.14 * 1^2 = 3.14
Then multiply by the height 3.14 * 5 = 15.7 cubic inches
The middle can's diameter is 5 inches so the radius is 2.5.
3.14 * 2.5^2 = 3.14 x 6.25 = 19.625
Multiply by the height 19.625 * 3 = 58.875 cubic inches
The bottom can's diameter is 6 inches, so the radius is 3. 3.14 * 9 = 28.26
Multiply by the height 28.26 * 2 = 56.52 cubic inches
15.7 + 58.875 + 56.52 = 131.095
B and E are the only correct answers.

Step-by-step explanation:
In general, you compare each line to the one before, and figure out what step was taken. Anything involving an arithmetic operation is allowed by the <Operation> Property of Order.
1. Matches the equation you're solving. This equation is Given.
2. The parentheses have been eliminated by multiplying their insides by the factor outside. The Distributive Property says you can do that.
3. The term 7x has been subtracted from both sides. The Subtraction Property of Order says you can do that.
4. The term -20 has been eliminated by adding 20 to both sides. The Addition Property of Order says you can do that.
5. Both sides have been divided by 18. The Division Property of Order says you can do that.
A quantity with an initial value of 240 grows exponentially at a rate of 9.5% every 2 decades. What is the value of the quantity after 52 years, to the nearest hundredth?
Answer: 303.870087962229
Simplify ≈303.87
Step-by-step explanation:
Grows 9.5%→r=0.095 Divide by 100
Grows every 2 decades: exponent of t2
(where t is in decades)
Write a function:
f(t)=240(1+0.095) ^t/2 Percent change every 2 decades
52 years→52/10→5.2 decades There are 10 years in a decade
Plug in t=5.2
f(5.2)=240(1+0.095) 5.2/2
Answer: 303.870087962229
≈303.87
Round to the nearest hundredth
