Answer:
a)
Verify is the corresponding sides have same ratio:
AB / DE = 50/60 = 5/6 BC / EF = 20/24 = 5/6Since the ratios are same, the triangles are similar
b)
If one dimension is same, the base areas will make difference by the square of the scale factor:
(6/5)² = 1.44 timesSolve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?
Answer:
x=42
Step-by-step explanation:
2(x-8)=68
Distribute the 2
2x-16=68
Use the addition property of equality (add 16 to both sides)
2x=68+16
2x=84
Use the division property of equality (divide both sides by 2)
x=84/2
x=42
The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

If fixed cost of 20 article is 500 and variable cost for each article is 40. Find the total cost function? Also ,find the total cost of 90 articles?
Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level.
The Variable cost is $40 and increases by every additional unit produced.
Assume the number of articles produced is a.
Cost function would be:
Total cost = Variable cost * Number of articles + Fixed cost
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100

Write the equation of the line that passes throught the points (-1, 6) and (5, -4).
Answer:
y = -5/3x + 13/3
Step-by-step explanation:
(-1, 6) and (5, -4).
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (5 - (-1))
Simplify the parentheses.
= (-10) / (5 + 1)
= (-10) / (6)
Simplify the fraction.
-10/6
= -5/3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -5/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (5, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = -5/3(5) + b
To find b, multiply the slope and the input of x(5).
-4 = -25/3 + b
Now, add 25/3 to both sides to isolate b.
-4 ⇒ -12/3
-12/3 + 25/3 = 13/3
13/3 = b
Plug this into your standard equation.
y = -5/3x + 13/3
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, 6).
y = -5/3x + 13/3
6 = -5/3(-1) + 13/3
6 = 5/3 + 13/3
6 = 18/3
6 = 6
Your equation is correct.
Hope this helps!

The volume of a cylinder is 980 in cubed.
The height of the cylinder is 20 in. What is the radius of the cylinder?
Express your answer to the nearest hundredth.
9514 1404 393
Answer:
3.95 in
Step-by-step explanation:
The volume is given by ...
V = πr²h
Solving for radius, we get ...
r = √(V/(πh))
For the given numbers, the radius is ...
r = √(980 in³/(π·20 in)) = 7/√π in ≈ 3.95 in
The radius of the cylinder is about 3.95 inches.

(−7x 2 −4)+(−7x 2 −6x−2)
-20
Explanation:
( − 7 ^ 2 − 4 ) + ( − 7 ^ 2 − 6 − 2 )
Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:
− 1 4 2 −6 −6
Figure that problem out then you will get -20.
Answer:
−14x^2 − 6x - 6
Step-by-step explanation:
(−7x 2 −4)+(−7x 2 −6x−2) should be written as (−7x^2 −4) + (−7x^2 −6x−2). The " ^ " symbol denotes exponentiation. 7x^2 means "7 times the square of x." We can immediately remove the parentheses, obtaining:
−7x^2 −4 −7x^2 − 6x − 2
Our next step is to combine like terms. For example, -7x^2 appears twice, with the same (negative) sign; summing these up results in -14x^2.
Immediately after doing that, we have:
−14x^2 −4 − 6x − 2
and need to combine the constants -4 and -2:
−14x^2 −6 − 6x
Finally, we write these terms in descending powers of x:
−14x^2 − 6x - 6

Answer:
B
Step-by-step explanation:
The graph of function is |x + 2| – 5= -(x - 1)(x - 3) which is represented in the graph option first is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
As we can see in the graph, there are two graphs of a function shown.
First one is a graph of a mod function and second one is a graph of a quadratic equation.
|x + 2| – 5= -(x - 1)(x - 3)
f(x) = |x + 2| - 5
g(x) = -(x - 1)(x - 3)
Thus, the graph of function is |x + 2| – 5= -(x - 1)(x - 3) which is represented in the graph option first is correct.

PLEASE HELP THIS HAS A TIMER The following two-way table shows the distribution of daily traffic and weather issues in a certain large city.
A 4-column table with 3 rows. Column 1 has entries bad weather, good weather, total. Column 2 is labeled heavy traffic with entries 25, 55, 80. Column 3 is labeled Light traffic with entries 5, 15, 20. Column 4 is labeled Total with entries 30, 75, 100. The columns are titled daily traffic and the rows are titled weather conditions.
Suppose a day from this city is selected at random. Let event A = heavy traffic and event B = bad weather. Are events A and B independent?
No, P(A) = P(B|A).
No, P(A) ≠ P(A|B).
Yes, P(A) = P(A|B).
Yes, P(A) ≠ P(B|A).
Answer:
I believe the answer is (B).
Both are not independent, and the probability of A is 30/100.
While the probability for A|B is like 30/100(80/100) which does not equal 30/100.
I've been trying to figure out how to do it and stuff, and this seems the most reasonable answer. I'm taking it now. Goodluck

The two events are not independent as the traffic is affected by the weather conditions.
What is independent probability?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).
Let event A = heavy traffic and event B = bad weather.
P(A)= 25/30 and P(B)=25/30
Two events are said to be independent only when the change in one event affect the other event.
Here the two given events are not independent.
Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.
Hence, the two events are not independent as the traffic is affected by the weather conditions.
