a) 15.6b) 12c) 36d) 51.6============================================
Explanations:
Part (a)
The area of a triangle formula is A = 0.5*b*h where b and h are the base and height. You could use 1/2 in place of the 0.5
We're focused on the blue shaded triangle, which is the "floor" so to speak of this pyramid. To find the floor area, we will use b = 6 and h = 5.2 and we get
A = 0.5*b*h = 0.5*6*5.2 = 15.6
For this problem, all areas are in square inches as denoted by the [tex]\text{in}^2[/tex]
If you're curious where the b = 6 came from, it's because all sides of the equilateral triangle are the same length.
Note: The base and height of a triangle are always perpendicular.
----------------------
Part (b)
Focus on any single non-shaded triangle. Let's say we focus on the upper triangle. We have b = 6 and h = 4. It then leads to the area A = 12 sq in. This is the area of one lateral face.
------------------------
Part (c)
The instructions state that the lateral faces are congruent triangles, aka they are identical triangles. So that means we have three copies of the same area we found back in part (b), which was 12. Therefore, the lateral surface area is 3*12 = 36 square inches. As your teacher mentions, we do not include the shaded triangle as part of this result (that will happen in part d below).
------------------------
Part (d)
We add the results of parts (a) and (c) together to get the full surface area. This is the total area of the flat net, and it corresponds directly to the full surface area because we fold up the 2D figure to get the 3D one.
The total surface area is 15.6+36 = 51.6 in^2

While sitting on a park bench, Tanisha counts that 16 out of 20 people who walk by her have a pet with them.
Part A. What is the probability that a person who walks by Tanisha has a pet?
Part B. What is the probability that a person who walks by her does not have a pet?
Answers
Answer:
the answer would be-
Step-by-step explanation:
The probability that a person who walks by Tanisha has a pet- 0.8
The probability that a person who walks by Tanisha does not have a pet- 0.2
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
Part A. The probability that a person who walks by Tanisha has a pet can be calculated by dividing the number of people who have a pet by the total number of people who walk by her. In this case, 16 out of 20 people have a pet, so the probability is:
P(having a pet) = 16/20 = 4/5 = 0.8
So, the probability that a person who walks by Tanisha has a pet is 0.8 or 80%.
Part B. The probability that a person who walks by Tanisha does not have a pet can be calculated by subtracting the probability of having a pet from 1. That is:
P(not having a pet) = 1 - P(having a pet)
P(not having a pet) = 1 - 0.8
P(not having a pet) = 0.2
So, the probability that a person who walks by Tanisha does not have a pet is 0.2 or 20%.

for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm

Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,

You buy 10 pounds of birdseed at Store A for $11.50. Your friend buys 15 pounds of birdseed at Store B for $19.50. How much less would you spend buying 20 pounds of birdseed at the store with the better deal and why?
Answers
Answer:
The answer is three
Step-by-step explanation:
$11.50/10 = $1.15 per pound
$19.50/15 = $1.30 per pound
$1.15 * 20= $23
$1.30 * 20 =$26
$26- $23 = $3
answer: $3
Answer: You would spend $3 less at store A with 23 and Store B with 26
Step-by-step explanation: Store B: 15 pounds / 19.50 = $1.3*20 =$26
Store A: 10pounds =11.50*2=$23
