A. 2 cm, 3 cm, 4 cm
B. 6 cm, 7 cm, 8 cm
C. 8 cm, 15 cm, 17 cm
D. 9 cm, 12 cm, 15 cm
Answer: D.
Step-by-step explanation:
If the triangle PQR has sides from biggest to smallest 3,4,5 we need another triangle with a similar ratio to compare it to.
9/3= 3 12/3=4 15/3=5
So the answer is D because I can divide all the sides of the new triangle by the same number to get the sides of triangle PQR
Answer:
D. 9 cm, 12 cm, 15 cmStep-by-step explanation:
Given
ΔLMN ~ ΔPQRΔPQR has sides ratio 3 : 4 : 5
ΔLMN should also have same ratio and the ratio of corresponding sides should be same.

what is the diameter in the circle above
7
3.5
14
3.14
Answer:
14
Step-by-step explanation:
The diameter is the length from one point on the circle to another, passing through the center. The radius is the length from a point on the circle to its center, so we can always find the diameter by doubling the radius. In this case, with a radius of 7, our diameter is 7 · 2 = 14

Answer:
6955 ftStep-by-step explanation:
Refer to attached. Point J, segment BJ and angle measures added.Step 1, find BJ
BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ftStep 2, find BP
BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ftStep 3, find PQ
PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ftStep 4, find the elevation of peak P

Answer:
G = 50
H = 80
I = 50
Step-by-step explanation:
Angle in a triangle is equal to 180. This means that we will equal all the angles to 180
2x + 2x + 4x-20 = 180
8x - 20 = 180
8x = 180 + 20
8x = 200
x = 200 / 8
x = 25
G = 2 * 25 = 50
I = 2 * 25 = 50
H = 4 * 25 - 20
H = 100 - 20 = 80

Step-by-step explanation:
Answer:
B and C
Step-by-step explanation:
Side lengths of 4, 8, and 12 do not form a right triangle. According to the Pythagorean Theorem, a² + b² = c². In this theorem, "c²" represents the largest side (c) squared
use the equation i=6j-10 to find i when j=2

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.
Cost of 8 friendship bracelets = $62.00
Therefore,
Cost of 1 friendship bracelets = $62.00/ 8
Cost of 1 friendship bracelets = 7.75
The cost of 1 friendship bracelets is $7.75

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?
Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15
Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?
Answer:
1 hour 42 minutes approx
Step-by-step explanation:
Given data
Mayas work rate= 1/4 room per hour
Reginald work rate= 1/3 room per hour
Let the total time taken for both of them be T
Hence their combined work rate
1/4+1/3= 1/T
3+4/12=1/T
7/12=1/T
T= 12/7
T= 1.7 hours
Hence it will take them 1 hour 42 minutes approx

Education researchers are interested in the workload expectations of freshmen at a local university. Since all of the freshmen are randomly placed into freshman seminar classes, the researchers randomly select 3 freshman seminar classes and survey all of the students within those classes. Which sampling method was used?
cluster sampling
simple random sampling
stratified random sampling
systematic random sampling
Answer: Cluster Sampling
Step-by-step explanation: I just took this test and got it correct :)
If the researchers choose three freshmen seminar classes at random and poll every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.
What is cluster sampling?In the probability sampling technique known as cluster sampling, you split a population into groups, such as districts or schools, and then randomly choose a sample from among these groups. Ideally, each cluster should be a small representation of the population as a whole.
When studying large, dispersed populations, cluster sampling is most effective since interviewing every individual would be expensive, time-consuming, and sometimes impossible.
By using cluster sampling, it is possible to create smaller, more comparable clusters that represent the population being studied.
Thus, the researchers choose three freshmen seminar classes at random and polled every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.
