Answer:
Step-by-step explanation:
hypotunes isnt involved(as the length inst given and we know it is hypotunes as it is the oppisite direction from the right angle)
so sohcahtoa
therefore ir toa
tan(x)=o/a
(tan inverse)tan^-1=34/54
oppisite= 34 as it is oppisite to teh angle your trying to find
and the adjacent is beetwen the right angle and the angle your mesuring
The angle x is 32.2° which is opposite to the side perpendicular of the length 34.
Right angled triangle:
A right angle triangle have one angle as right angle, the side opposite to the right angle is called hypotenuse and the side on which angle 90 degree is created is called base. The third side is called perpendicular.
Here we have given that
Perpendicular = CD = 34
Base = BC = 54
If we apply tan on this triangle we will find the relation between angle B, CD and BC.
How to use tan into right angle triangle?we know that
tan x = [tex]\frac{perpendicular}{base}[/tex]
Using tan into our given triangle we have
[tex]tanx=\frac{CD}{BC}[/tex]
[tex]tanx=\frac{34}{54}[/tex]
[tex]tanx=0.629629[/tex]
[tex]x=tan^-1(0.629629)\\\\x=32.2[/tex]
Hence the final answer is 32.2°

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.
= 101

[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
3
12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18
4
5x + 14 = - 7 ( subtract 14 from both sides )
5x = - 21 ( divide both sides by 5 )
x = - [tex]\frac{21}{5}[/tex] = - 4.2

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
A company makes 5 blue cars for every 3 white cars it makes. If the company makes 15 white cars in one day, how many blue cars will it make?
Answer:
25
Step-by-step explanation:
25, because 3 times what is 15, 5. So multiply 5 by 5 and get 25.
Answer:
25
The set-up would go something like this:
3 * x = 15
x is our variable that isn't defined, bur by doing some simple math we can determine that "x" is 5 becuase of simple logic and reasoning.
This means that you would also have to multiple the 5 by the 5 as well since we know that for every 3 white cars there is 6l5 blue cars.
this would bring the total to 25z hope this helped :)

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.

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
