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
--------------------------
Side note: Another name for "triangular pyramid" is "tetrahedron". The "tetra" means "four", and "hedron" means "face".

Answer:
-4°C
Key:
( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8
Step-by-step explanation:
If it was -9°C and it INCREASED by 5°C, you need to ADD.
-9°C + 5°C
*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and make it either positive or negative, depending on which absolute value is the greatest (|9|).*
-9°C + 5°C OR |9| - |5|
|9°C| - |5°C| = |4°C| = -4°C
(because the greatest absolute value, |9|, is negative, the answer is too.)
HOPE THIS HELPS :DWhich value of x makes the equation true?

For x = -6
Step-by-step explanation:
1.5x + 5 = -4
1.5x = -4 - 5
1.5x = -9
x = -6
Checking: 1.5 * -6 + 5 = -4
1. You subtract 5 to both sides
2. divide 1.5 to the other number

Which graph represents the solution of 3y-9≤6x?
Answers
The graph that represents the solution of 3y - 9 ≤ 6x is option A.
Option A is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
3y - 9 = 6x
We can find the following coordinates.
When x = 0,
3y - 9 = 0
3y 9
y = 3
When y = 0,
3y - 9 = 6x
-9 = 6x
x = -9/6
x = -3/2
x = -1.5
Thus,
The graph on option A represents the solution.

Step-by-step explanation:
Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.
1) change 6.8 into fraction: 34/5
2) rewrite: 34/5 divide by 4/5

A bag contains 5 yellow balls 3 red balls and 2 green balls. A ball is removed from the bag without looking, the colour recorded, and then returned the bag. A second ball is drawn and its colour is also recorded.
c) What would be the outcome of the 2 balls if it has a probability of 1/10?
Answers
Answer:
the two balls are yellow and green, in either order.
Step-by-step explanation:
P(Y) = 5/10 = 1/2
P(R) = 3/10
P(G) = 2/10
Since the only combination that makes a product of 1/10, so
P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10
So the two balls are yellow and green, in either order.

Answers
Answer:
The numbers are 44 and 36
Step-by-step explanation:
n + n - 8 = 80
2n - 8 = 80

2n = 88
2n/2 = 88/2
n = 44
44 - 8 = 36
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%.
