Answer:
960 cm^3
Step-by-step explanation:
The volume of any object is found by multiplying the area of the base times the height. I'll use the triangular sides as the base in this case. The area of the triangle is (bh)/2, so this calculation is:
(16x12)/2 = 96
The height is 10, so Volume is 96 x 10 = 960 cm^3
Two game board spinners are shown below, one number 1, 2, 3, and one numbered 5, 6, 7, and 8. A contestant gets to spin both needles just once to win money. The first spinner points to the tens digit and the second points to the digit of their prize. For example, if they spin a 3 and a 6 they win $36.

What is a tree diagram?A tree diagram is a tool used in general mathematics, probability, and statistics to compute the number of alternative outcomes of an event or issue and to arrange those potential outcomes.
Since the first spinner has 3 outcomes, the second spinner has 4 outcomes. Therefore, the total number of outcomes will be 12.
Hence, the tree diagram can be drawn as shown below.

Answer:
Option A for part (a) and Option B for part (b)
Step-by-step explanation:
Step 1: Determine the ratios in part a
First Batch --> 8 minutes / 2 customers = 4 minutes per customer
Second Batch --> 18 minutes / 6 customers = 3 minutes per customer
Third Batch --> 21 minutes / 7 customers = 3 minutes per customer
In part (a) we would choose option a which is that it does not always take the same amount of time to serve each customer.
Step 2: Determine the ratios in part b
First Batch --> 27 points / 3 dollars = 9 points per dollar
Second Batch --> 45 points / 5 dollars = 9 points per dollar
Third Batch --> 63 points / 7 dollars = 9 points per dollar
In part(b) would choose option b which is that each dollar spent appears to earn the same number of points which would give us 8 dollars for 72 points.
Answer: Option A for part (a) and Option B for part (b)
Calculate the perimeter of the shape below
Answer: The answer is C ≈ 18.85 meters.
Step-by-step explanation: The formula that you need is...
2 × π (pi or approximately 3.14) × r (which is the radius)
In this case, your radius is 3, so you solve by 2 × π (pi or approximately 3.14) × 3 which equals 18.8495559215 but you round to your nearest hundredth which gets you to have 18.85 meters as your answer! I hope this helps!
radius= 3 m
to find:the perimeter of the circle.
solution:[tex]perimeter = 2\pi \: r[/tex]
[tex]p = 2 \times \pi \times 3[/tex]
[tex]p = 18.84956[/tex]
[tex]p = 18.95[/tex]

PLEASE I NEED HELP!!!
Answer:
1/27
Step-by-step explanation:
Okay first, calm down. Math is always hard when your stressed.
First step is to elimate b and write the equation in terms of a. So rearrange a-b=3 to b=a-3. Substitue that into the equation. Now you have :
27^1/3(a-3)
---------------
9^1/2(a)
Now rewrite the equation in terms of 3, you do this by realizing that 9 is simply 3^2 and 27 is simply 3^3. This gives you
3^(a-3)
---------
3^a
Now you use the laws of powers, and you get 3^-3, which is essentially 1/27.

The median rainfall during a spring storm in the lowlands is about 4 mm less than a spring storm in the highlands. The mean rainfall for the lowlands is about 3 mm less than for the highlands. Why is there a difference in the central measures for each data set?
Answer:
There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.
Step-by-step explanation:
Answer:
There is a difference since there could be more rainy days in the spring than on other days. As a result, the mean for the spring would be higher than on other days.

A bicycle manufacturer is studying the reliability of one of its models. the study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent. if the probability of a defect with the brakes or the chain is 6 percent, what is the probability of a chain defect? 1.5 percent 2 percent 2.5 percent 3 percent
Using Venn probabilities, it is found that there is a 0.03 = 3% probability of a chain defect.
What is a Venn probability?In a Venn probability, two non-independent events are related to each other, as are their probabilities.
The "or probability" is given by:
[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)[/tex]
In this problem, the events are:
Event A: Brake defect.
Event B: Chain defect.
For the probabilities, we have that:
The study finds that the probability of a brake defect is 4 percent, P(A) = 0.04.The probability of both a brake defect and a chain defect is 1 percent, P(A∩B) = 0.01.The probability of a defect with the brakes or the chain is 6 percent, P(A∪B) = 0.06.Substitute all the values in the formula
[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)\\\\0.06=0.04+P(B)-0.01\\\\P(B)=0.06-0.04+0.01\\\\ P(B)=0.03[/tex]
0.03 = 3% probability of a chain defect.
Hence, there is a 0.03 = 3% probability of a chain defect.

If r= 3 cm, p = 2.4 cm, q = 1.8 cm, and m= 4.35 cm, what is the measure of n?
Answer:
C
Step-by-step explanation:
given the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{LM}{PR}[/tex] = [tex]\frac{LN}{PQ}[/tex] ( substitute values )
[tex]\frac{n}{1.8}[/tex] = [tex]\frac{4.35}{3}[/tex] ( cross- m ultiply )
3n = 7.83 ( divide both sides by 3 )

Answer:
Step-by-step explanation:
When we add the area of semicircle I and III of same radius, we get a cirlce.
diameter = 48 cm
r = 48/2 = 24 cm
Area of I and III = area of circle
= πr²
= 3.14 * 24 *24
= 1808.6 cm²
Figure II:
length = diameter of the bigger semicircle = 48 cm
width = diameter of the smaller circle = 14 cm
Area of rectangle (figure II) = length *width
= 48 * 14
= 672 cm²
Smaller semicircle A & B
diameter = 14 cm
r = 14/2 = 7 cm
Area of Semicircle A & B = Area of a circle
[tex]\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}[/tex]
Area of shaded region = area of rectangle II + area of figure I & III - area of A &B
= 672 + 1808.6 - 154
= 2326.6cm²

three friends Luke nick and serena are kicking a soccer ball to each other on the beach Luke kicks the ball to Serena who kicks the ball to nick, who kicks the ball back to Luke. the friends location on the beach are drawn on a coordinate plane as shown where the x values and y represent distance in feet.
WHAT IS THE APPROXIMATE DISTANCE THE BALL TRAVELS AFTER MAKING A FULL ROTATION AROUND THE TRIANGLE OF FRIENDS?
A. 288 feet
B.57.94 feet
C. 144 feet
D. 67.91 feet
The approximate distance the ball travels after making a full rotation around the triangle of friends is: B. 57. 94 feet.
Total distanceLuke ( 4,10)
Nick (-8, -2)
Serena (4, -14)
Hence:
Distance between two points=√(x2-x1)²+ (y2-y1)²
Distance between Luke and Nick=√ (-8, -4)²+ ( -2-10)²
Distance between Luke and Nick=√288
Distance between Luke and Nick=16.97 feet
Distance between Luke and Serena=10-(-14)
Distance between Luke and Serena=24
Distance between Nick and Serena=√ (-8, -4)²+ ( -2+14)²
Distance between Nick and Serena=√ 288
Distance between Nick and Serena=√16.97 feet
Total distance=16.97 feet+16.97 feet+ 24
Total distance=57.94 feet

a
What is the area of the base of the pyramid?
Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.
