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".

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?
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

If two sectors have an area of 12π square units, and one sector is from a circle with radius 6 units, while the other is from a circle with a radius of 4 units, how do the central angles for these sectors compare?
Answer:
Thus, the ratio of the central angles is 4 : 9.
Step-by-step explanation:
Area, A = 12 π square units
radius, R = 6 units
radius, r = 4 units
Area of sector is given by
[tex]A=\frac{\theta }{360}\times \pi r^{2}[/tex]
For first sector
[tex]12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}[/tex]
For second sector
[tex]12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}[/tex]
So, the ratio is
[tex]\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9[/tex]
Answer:
4 : 9
Step-by-step explanation:
Given:
Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.
Find ratio of central angles.
Solution:
Let A = central angle
Area of a sector = pi r^2 (A/360)
Since both sectors have the same area,
pi r1^2 (A1/360) = pi r2^2 (A2/360)
simplifying
A1 r1^2 = A2 r2^2
Therefore
A1 : A2 = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9

Answer:
Hope this helps you
The diameter is 1 unit
Step-by-step explanation:
The circumference is 3.14 units
C = pi * d
Using 3.14 for pi
3.14 = 3.14 d
Divide each side by 3.14
3.14/3.14 = 3.14 d/ 3.14

Marsha Deposited $5,500 into a savings account 5 years ago. The simple interest rate is 2%. How much money did Marsha earn in interest?
Answer: $550.00
Step-by-step explanation: Equation: I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 5500 × 0.02 × 5 = 550
I = $ 550.00
The simple interest accumulated
on a principal of $ 5,500.00
at a rate of 2% per year
for 5 years is $ 550.00.

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?
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%.

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?
With step by step explanation = Brainliest
Answer:
don't know
Step-by-step explanation:
ok please mark mr brainlist
Answer:
3%
Step-by-step explanation:
Interest rat is calculated by using the equation A = P(1 + r)^n
A is the amount after interest. Here, it is 1635.30
P is the principal, or base, amount. Here, it is 1422
r is the rate at which there is interest. It is what we need to find out.
n is the amount of years interest is calculated for. Here, it is 5
Now that we have everything, we calculate:
1635.30 = 1422(1 + r)^5
Now we have to get r on one side of the equation by itself:
Divide both sides by 1422:
1635.30/1422 = (1 + r)^5
5√(1655.30/1422) = 1 + r
5√(1.16406469) - 1 = r
Now r is on one side of the equation.
The 5th root of 1.16406469 is 1.03084987
1.03084987 - 1 = 0.0308, so it is 3%
The 5√ is the 5th root of the numbers
Or it's 2.835 percent I don't know
In a packet of mixed candies there are 2 fruit centers for every 3 caramel centers. There are 30 candies in the packet. How many caramel centers are there?
Answer:
18 Caramel Centers
Step-by-step explanation:
Solution
So first off, we can group 2 and 3 toghether to make one "packet" with 5 candies in it. Now, we can divide 5 by 30 and get 6. Now we know how many packets/candies there are. After that, we can multiply 6 with 3 to get 18 caramel centers.
Verification:
2 x 6 = 12
3 x 6 = 18
12 + 18 = 30 ✅
