Classify the triangle shown below. Check all that apply.
The shown triangle is scalene and right, so the correct options are C and F.
How to identify the shown triangle?
First, we can see that the 3 sides have different measures. So the triangle is Scalene (and we discard options A and E).
We also can see that one of the angle is 90°, which means that we have a right triangle. So option C is correct. (And we discard B and D).
Concluding, we have a scalene right triangle. So the correct options are C and F.

Find the volume of the prism.
5 units
2 units
8 units
Answer:
80 units.
Step-by-step explanation:
If it is a rectangular prism, then it is 5×2×8, which is 10, from the 5×2 and 8. 10×8 is 80. So the final answer is 80 units cubed. Hope this helps! If you are still confused, please comment so I can help you!
Rectangular Prism: 80 units^3
V = lwh = 5(2)(8) = 80 units^3
Triangular Prism: 40 units^3
V = [tex]\frac{bhl}{2}[/tex] = [tex]\frac{5(2)(8)}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40 units^3

Step-by-step explanation:
Leo wants to determine the average number of texts middle school students send in a day. Since all middle school students are enrolled in history, he randomly surveyed 4 students from each of Mr. Barnes’s eighth-grade history classes. Ms. Lopez and Mrs. Frank also teach eighth-grade history. What should Leo do to ensure his sample is representative of all middle school students?
He should take the sample as is because he randomly surveyed students in each of Mr. Barnes’s classes.
He should also take a sample from Ms. Lopez’s and Mrs. Frank’s classes so that each student has the same chance of being chosen.
He should also take a sample from each of the other history classes in all of the other grades in the middle school.
He should survey all the students in all the history classes to make sure he collects enough data.
Answer:
In order for his sample to be representative of all middle school students Leo: C) Should also take a sample from each of the other history classes in all of the other grades in the middle school.
What is sample?
Sample can be defined as the data that is randomly collected by a researcher so as to reach or draw a conclusion.
Since only one grade is being surveyed which is Mr. Barnes’s eighth-grade history classes, he should as well carryout the survey on Ms. Lopez and Mrs. Frank history class.
In conclusion he should also take a sample from each of the other history classes in all of the other grades in the middle school.
Final answer:
Leo should improve his survey method by sampling students from all eighth-grade history classes, including those of Ms. Lopez and Mrs. Frank, to ensure that each student has an equal chance of being selected and to obtain a representative sample of the middle school population.
Explanation:
Leo aims to determine the average number of texts middle school students send in a day. To ensure his sample is representative of the entire middle school student population, he should consider the sampling method. While he randomly surveyed students from Mr. Barnes’s eighth-grade history classes, only selecting students from a single teacher's classes might not guarantee a representative sample.
Thus, Leo should extend his survey to include students from Ms. Lopez’s and Mrs. Frank’s classes, which will give every student an equal chance of being chosen. This is important because it would include a wider range of perspectives and reduce the chance of sample bias. If Leo's goal is to understand the average texting behavior of all middle school students, and not just those in eighth grade, he should ideally sample students from other grades as well. However, if his focus is specifically on eighth graders, then sampling from all eighth-grade history classes should suffice.

If you had 20 equal parts, how would you shade in 20% of it? How much parts would you have shade in?
Answer:
4
Step-by-step explanation:
20 percent is 1/5. 1/5 of 20 is 4.
You would need to shade in 4 parts.
20% of something is equal to 1/5 (because 100/5=20), so you would need to find 1/5 of 20. You can do this by dividing 20 by 5, and 20 ÷ 5 = 4.

Step-by-step explanation:
Please let me know if it is right
The volume of a dollhouse is V=24×8×10+1/2 ×24×6×8. Therefore, the correct answer is option A.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, Jasper built a dollhouse for his younger sister.
A rectangular prism has a length of 24 inches, width of 8 inches, and height of 10 inches.
We know that, the formula to find the volume of a rectangular prism is Length×Width×Height
Now, V₁ =24×8×10
= 1920
A triangular prism has a triangular base of 24 inches and height of 6 inches. The height of the prism is 8 inches.
V₂=Area of triangle ×Height
= 1/2 ×24×6×8
= 12×6×8
= 576
So, equation is V=V₁+V₂
V=24×8×10+1/2 ×24×6×8
Therefore, option A is the correct answer.

Captain Ben has a ship, the H.M.S Crimson Lynx. The ship is four furlongs from the dread pirate Umaima and her merciless band of thieves.
If his ship hasn't already been hit, Captain Ben has probability 3/4 of hitting the pirate ship. If his ship has been hit, Captain Ben will always miss.
If her ship hasn't already been hit, dread pirate Umaima has probability 1/2 of hitting the Captain's ship. If her ship has been hit, dread pirate Umaima will always miss.
If the Captain and the pirate each shoot once, and the pirate shoots first, what is the probability that both the pirate and the Captain hit each other's ships?

Write an explicit formula for the sequence. Use this, to find the 80th term of the sequence that begins: -3,1,5,9....
Answer:
see explanation
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
9 - 5 = 5 - 1 = 1 - (- 3) = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 4, thus
[tex]a_{n}[/tex] = - 3 + 4(n - 1) = - 3 + 4n - 4 = 4n - 7 ← explicit formula
Thus
[tex]a_{80}[/tex] = 4(80) - 7 = 320 - 7 = 313
Matias' stepmother uses a 30%-off coupon to buy the ingredients for huevos rancheros.
She spends $28.
» What is the regular price, r, of the ingredients before the discount?
Enter the amount
Answer:
$40Step-by-step explanation:
To determine the regular price r of the ingredients before the discount, we have to consider that $28 represents 70% of the regular price as this amount has a 30% discount and with that, find the price that represents 100%:$28 → 70% r ← 100%r=($28*100%)/70%= $40The regular price r of the ingredients before the discount is $40.The regular price, r of the ingredients before the discount is $40.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number. So the percentage actually means a part per 100.
Percentage is usually denoted by the symbol '%'.
Amount spent by Matias' stepmother to buy the ingredients for huevos rancheros = $28
This is the discounted price after a 30% off discount.
Let the regular price be x.
x - (30% of x ) = 28
x - (0.3 x) = 28
0.7x = 28
x = 28 / 0.7
x = 40
Hence the original price of the items is $40.
