Answer:
[tex] \huge{ \fbox{ \sf{10}}}[/tex]
Step-by-step explanation:
Remember that The sum of the interior angles of a triangle is two right angles ( 90 + 90 ) or 180 . Create an equation:
[tex] \sf{ \: 8x + 60 + 40 = 180}[/tex]
In the question, we are asked to find the value of x.
Now , Add the numbers : 60 and 40
[tex] \longrightarrow \sf \: 8x + 100 = 180[/tex]
Move 100 to RHS ( Right Hand Side ) and change it's sign
[tex] \longrightarrow{ \sf{8x = 180 - 100}}[/tex]
Subtract 100 from 180
[tex] \longrightarrow{ \sf{8x = 80}}[/tex]
Divide both sides by 8
[tex] \longrightarrow{ \sf{ \frac{8x}{8} = \frac{80}{8} }}[/tex]
[tex] \longrightarrow{ \sf{x = 10}}[/tex]
The value of x is 10
Hope I helped!
Best regards! :D

11+102 +73 = 186 total killed for ivory = 186 Total killed 19 + 129 + 139 = 287. What percent of the total elephants killed does this number represent? Student Response: Show calculations and answer.
Answers
Answer:
64.8% of elephants were killed for ivory
Step-by-step explanation:
divide the number of elephants killed for ivory by the total number of elephants killed: 186÷287= 0.6780
multiply your answer by 100 to get a percentage: 0.6780 x 100= 67.8%
67.80% percent of the total elephants killed does this number represent.
What is Percent?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is primarily used to compare and determine ratios and is represented by the symbol %.
Given:
Total elephants killed for ivory= 186
Total elephants killed = 287.
So, the percent of the total elephants killed does this number represent
= 186 / 287 x 100
= 0.6780 x 100
=67.80%
Hence, the 67.80% percent of the total elephants killed does this number represent.

================================================================
Explanation:
S = number of tons of sugar
150S = cost of transporting all S tons of sugar
150S+4500 = total cost since we add on the $4500 fixed cost
C = 150S+4500 is the cost equation
--------------------------
If we replace C and S with y and x (in that order), then the equation turns into y = 1500x+4500
To graph this, you only need two points since this is a linear equation in the form y = mx+b. We have m = 1500 as the slope and b = 4500 as the y intercept.
To find a point, you plug in some number for x to get a corresponding y value. For instance, if x = 0
y = 1500x+4500
y = 1500(0)+4500
y = 4500
Showing (0,4500) is the y intercept and one point on the line
Now plug in x = 1
y = 1500x+4500
y = 1500(1)+4500
y = 6000
Showing (1,6000) is another point on the line
You can keep going to generate more points, but two is enough.
The graph will be a straight line through (0,4500) and (1,6000)

Which model would best describe the population of a city if it increases in size by a factor of two every 29 years?
A)doubling time growth model
B) learning curve model
C) logistic curve model
D) half-life decay model
Answers
Answer:
A) doubling time growth model
Step-by-step explanation:
Doubling time growth model can be defined as the total or overall number of time it takes for a specific quantity to increase by doubling in value or size at a constant growth rate.
Mathematically, the doubling time growth model is given by the rule of 70;
[tex]dt = \frac{70}{r}[/tex]
Where,
dt represents the doubling time.
r is the growth rate.
Hence, a doubling time growth model would best describe the population of a city if it increases in size by a factor of two every 29 years. The doubling time growth model is typically used to study or model the human population growth.

An employee put $10.000 in a retirement
account that offers 4%, interest
Compounded annually.
The employee makes no additional deposits or
withdrawals. Which amount is closest to the interest
the employee will have earned at the end of 12 years?
Answers
Answer:
Interest earned after 12 years is $48,000.
Step-by-step explanation:
The first step is to find 4% of 10,000
10,000 times .4 equals to 4,000
4% of 10,000 is 4,000
So each year, $4,000 is added
Times $4,000 by 12 years and you will have the total interest earned.
In case you need to know, the total amount of the bank account should be $58,000.
