A. less than 7 cm
B. between 7 cm and 8 cm
C. between 8 cm and 9 cm
D. greater than 9 cm
2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?
Answer:
65^2
Step-by-step explanation:
if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.
#1:
Between 8 cm and 9 cm
Work:
SA = 6s^2
390 = 6 s^2
390/6 = 6s^2 /6
65 = s^2
sqrt(65) = s
s = 8.06
#2:
The total surface area of the triangular pyramid is 107 * square feet.
What is a triangular pyramid?
Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.
We are given that;
The length of median from outer triangle to side of the inner triangle is 8 ft
Side of inner equilateral triangle is 12 ft
Now,
First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:
a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).
a^2 + (m/2)^2 = b^2
b^2 = 6^2 + 8^2/4
b^2 = 36 + 4
b^2 = 40
b = sqrt(40)
b = 2 * sqrt(10)
So the height of the outer triangle is:
h = b * sqrt(3)/2
h = sqrt(30)
Now we can find the area of each equilateral triangle using the formula:
A = (sqrt(3)/4) * s^2
For the inner triangle:
A_inner = (sqrt(3)/4) * 12^2
A_inner = 36 * sqrt(3)
For the outer triangle:
Now we can find the area of the base, which is just the area of the inner equilateral triangle:
A_base = A_inner
A_base = 36 *
Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:
SA = A_inner + 3 * A_outer + A_base

EXPERT HELP: Some species can reproduce sexually or asexually. In which two situations is sexual reproduction advantageous?
A. When no individuals of the same species are available for mating
B. When many individuals of the same species are available for
mating.
C. When the individuals live in a stable environment in which they
thrive.
D. When the individuals live in an environment that suddenly
changes.
answer: B,C
Step-by-step explanation:
to be able to reproduce sexually you need enough of the same species to mate with. A says no individuals to reproduce with but for that it would be better if they were asexual. D says they change living environment and that usually changes the amount of same species animals that are around to reproduce with.
B. Now, assume that all of these circles have a radius of two. Then, calculate the ratio of a proximate circumference to the diameter.

Hayden drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?
Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.
Given:
Daily base pay = $200
Earnings per mile driven = $0.25
Cost of the laptop = $1800
Average miles driven per day = 300
The basic arithmetic operations have been used to solve this question
1. Calculating the total earnings per day.
Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)
Total earnings per day = $200 + ($0.25 × 300)
Total earnings per day = $200 + $75
Total earnings per day = $275
2. Determining the number of days required to save enough money for the laptop.
Number of days = Cost of the laptop ÷ Total earnings per day
Number of days = $1800 ÷ $275
Number of days ≈ 6.545 (rounded to the nearest whole number)
Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

Amalia wants to pour all of the water from Container 1 into Container 2. What must the height of Container 2 be in order for it to hold exactly the same amount of water as Container 1?
Note: Find the volume of container 1 first. Then use the same volume to solve for the missing height of container 2.
Show your work and write your answer on the line in the space below.
9514 1404 393
Answer:
18 in
Step-by-step explanation:
The volume of each container is the product of its dimensions:
V = LWH
We can let h represent the unknown height of Container 2. The volumes are equal when ...
32·18·12 = 24·16·h
(32·12·18)/(16·24) = h =18 . . . . . divide by the coefficient of h, simplify
The missing height of Container 2 is 18 inches.
Mr. Aamodt bought a new lawn tractor for $3,350.
a. The state sales tax on the lawn tractor purchase will be 6.5%. How much state sales tax will Mr. Aamodt pay on the tractor? (2 points)
b. Mr. Aamodt has applied for a 2‐year loan at the bank for $3,350 to pay for the new lawn tractor. The bank will charge him 8.4% simple interest on the loan. What amount of interest will Mr. Aamodt pay on the loan? (2 points)
c. What is the total cost of Mr. Aamodt’s new lawn tractor, including the purchase price, the loan interest, and the sales tax? (2 points)
Answer:
A) 217.75 sales tax
B)281.40 he will pay on the loan
C)$3849.15 he will pay including total cost, interest, and tax
Step-by-step explanation:
A)
To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.
B)
This is the same for loan.
3350x0.084=281.40 he will pay for loan.
C)
Now add it all up. 3350+217.75+281.40=3849.15
Answer:
The correct answers are:
a. $217.75!
b. $281.40!
c. $3,849.15!
Step-by-step explanation:
a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)
3,350 x 0.065=217.75
so the sales tax is $217.75
b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).
3,350 x 0.084 = 281.40
so the loan is $281.40
c. This time, sum the original price with both the loan and sales tax.
3,350 + 217.75+ 281.40= 3849.15
so the total cost for the new tractor is $3,849.15

What is the area of this parallelogram?
Answer:
25 cm
Step-by-step explanation:
The distance that a object covered in time was measured and recorded in the table. What equation would describe this motion?
y = 2x
y = 4x + 2.5
y = 4x + 4
y = 1.5x + 4.0
Answer:y = 1.5x + 4.0
Step-by-step explanation:
This is because the equation relates the distance traveled (y) to the time elapsed (x) through a linear relationship with a slope of 1.5, which represents the object's speed in meters per second, and a y-intercept of 4.0 meters, which represents the initial position of the object at time zero.
I'm pretty sure.
The equation that describes the motion of the object is y = 2x (option a)
Let's calculate the slope (m) using the values from the table. We take any two points (x₁, y₁) and (x₂, y₂) from the table:
(x₁, y₁) = (1, 2.0)
(x₂, y₂) = (5, 10.0)
The slope (m) is given by:
m = (y₂ - y₁) / (x₂ - x₁)
m = (10.0 - 2.0) / (5 - 1)
m = 8.0 / 4
m = 2.0
Now that we have the slope (m), we can determine the equation:
y = mx + b
Using one of the points from the table (1, 2.0) and the calculated slope (m = 2.0), we can solve for the y-intercept (b):
2.0 = 2.0 * 1 + b
2.0 = 2.0 + b
b = 2.0 - 2.0
b = 0
So, the Answer is option (a) y = 2x
