(50 pts, will mark brainliest) Classify Angle 3 & Angle 4 by choosing the correct term from the choices below.
A) adjacent
B) complementary
C) vertical
D) straight
Answer:
Adjacent
Step-by-step explanation:because it is right next to 4
The correct term that can be used to classify angles 3 and 4 is: A) adjacent.
What are Adjacent Angles?If two angles lie next to each other and they share one side and a vertex, then, both angles can be called adjacent angles.
An example of such angles that share a common side and a vertex are angles 3 and 4 as shown in the image.
Therefore, the correct term that can be used to classify angles 3 and 4 is: A) adjacent.

Step-by-step explanation:
If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent.
and if it has no solutions (lines are parallel), then it is inconsistent.
I think that information can be easily found on the internet.
so, the first one on the left is consistent independent. it has a unique solution at (-2, 1). the solution is always the crossing point of the lines.
the middle system is consistent dependent. both lines are identical, and so we have infinite many "crossing points" or solutions.
the right system is inconsistent, as 2 parallel lines have no solution at all.

[tex]\frac{2}{3}[/tex] x - 4 = 20 ( multiply through by 3 to clear the fraction )
2x - 12 = 60 ( add 12 to both sides )
2x = 72 ( divide both sides by 2 )
x = 36
2
4 = [tex]\frac{-1+x}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
8 = - 1 + x ( add 1 to both sides )
9 = x

12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18

8(3f-6)<-24 solve each inequality.
Answer:
f < 1
Step-by-step explanation:
8(3f−6)<−24
Divide both sides by 8. Since 8 is positive, the inequality direction remains the same.
3f−6< [tex]\frac{-24}{8}[/tex]
Divide −24 by 8 to get −3.
3f−6<−3
Add 6 to both sides.
3f<−3+6
Add −3 and 6 to get 3.
3f<3
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
[tex]f<\frac{3}{3}[/tex]
Divide 3 by 3 to get 1.
f < 1
Solution:
Note that:
Given inequality: 8(3f - 6) < -24Simplify the inequality to obtain the inequality for f.
8(3f - 6) < -24=> (24f - 48) < -24=> 24f - 48 < -24=> 24f < -24 + 48=> 24f < 24=> f < 1The simplified inequality is f < 1.
A scientist is studying wildlife in Ohio and she estimates that the population of bats is tripling every year. If she had counted 3000 bats in 2017, how many will there be in 2021?
The number of bats that there would be in 2021 would be 768,000.
What would be the number of bats in 2021?The formula that can be used to determine the future value of bats in 2021 is:
FV = P (1 + r)^n
Where:
FV = Future value P = Present value = 3000R = interest rate = 300%N = number of years = 43000(1 + 3)^4
3000 x 4^4 = 768,000

A shipping container will be used to transport several 120-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24500 kilograms. Other shipments weighing 12300 kilograms have already been loaded into the container. What is the greatest number of 120-kilogram crates that can be loaded into the shipping container?
Answer:
101
Step-by-step explanation:
The leftover weight that can be put onto the container (x)
x = 24500 - 12300
x = 12200
The amount of crates that can be hauled into the container
x = 12200 / 120
= 101.6667
We need a whole number so we round down.

Find the exponential function that passes through the points (2,80) and (5,5120)
Answer:
y = 5·4^x
Step-by-step explanation:
If you have two points, (x1, y1) and (x2, y2), whose relationship can be described by the exponential function ...
y = a·b^x
you can find the values of 'a' and 'b' as follows.
Substitute the given points:
y1 = a·b^(x1)
y2 = a·b^(x1)
Divide the second equation by the first:
y2/y1 = ((ab^(x2))/(ab^(x1)) = b^(x2 -x1)
Take the inverse power (root):
(y2/y1)^(1/(x2 -x1) = b
Use this value of 'b' to find 'a'. Here, we have solved the first equation for 'a'.
a = y1/(b^(x1))
In summary:
b = (y2/y1)^(1/(x2 -x1))a = y1·b^(-x1)__
For the problem at hand, (x1, y1) = (2, 80) and (x2, y2) = (5, 5120).
b = (5120/80)^(1/(5-2)) = ∛64 = 4
a = 80·4^(-2) = 80/16 = 5
The exponential function is ...
y = 5·4^x

Type a comma to separate the digits and type the $ symbol when you enter your answer as shown below:
Example: $10
Using proportions, it is found that the Customer Acquisition Cost was of $1,215.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.
80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:
97200/80 = $1,215.
