Step-by-step explanation:
a= -9, b= -4.8 and c = 8
Evaluating in steps:
-c+b-a=- 8 + (-4.8) - (-9) =- 8 - 4.8 + 9 = (9 - 8) - 4.8 = 1 - 4.8 = - 3.8Why do you think wars cause periods of high inflation

A burst of electromagnetic radiation has a frequency of 1 exahertz. One exahertz equals 10^12 megahertz. Each megahertz is equal to 10^6 hertz. What was the frequency of the burst of radiation in hertz? (^ indicates an exponent) *
Answer:
The frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.
Step-by-step explanation:
Since the frequency of the burst of electromagnetic radiation is 1 exahertz, and 1 exahertz = 10¹² megahertz. So, the frequency of radiation is 10¹² megahertz. Also 1 megahertz = 10⁶ hertz. So, 10¹² megahertz = 10¹² × 1 megahertz = 10¹² × 10⁶ hertz = 10¹² ⁺ ⁶ hertz = 10¹⁸ hertz.
So the frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

what value of n makes the equation ? 4(0.5-3)=n-0.25(12-8n)
Answer:
4(0.5-3)=n-0.25(12-8n)
2-12=n-3+2n
-10=-3+3n
-10+3=3n
-7=3n
n=-2.3
Answer: n= -7/3
Step-by-step explanation:
4(0.5 - 3) = n - 0.25(12 -8n) solve for n .
2 - 12 = n - 3 + 2n
-10 = 3n - 3

for the past five baseball seasons miguel had 122 45 109 124 and 115 hits what is his median number of hits for the past five seasons
Answer:
His median hit = 115
Step-by-step explanation:
Given:
122 45 109 124 and 115 hits
To find his median hit, you will either arrange the hits in ascending order or descending order
In ascending order (lowest to highest value)
45, 109, 115, 122, 124
In descending order (highest to lowest value)
124, 122, 115, 109, 45
It can be observed that thehe hits are 5
The median is the middle value
From either the ascending or descending order arrangement, 115 is the middle hit.
Therefore, his median hit = 115
What is the domain of the function graphed below?
Answer:
Domain: 0, 5
Range: 0, 2
Step-by-step explanation:
The Domain is the first coordinate which is x.
The Range is the second coordinate which is y.
Hope This Helps :)
The domain of the function will be 0 < x ≤ 5. The correct option is A.
What is a domain?In mathematics, a domain typically refers to a set of values for which a particular function or equation is defined. For example, the domain of the function f(x) = 1/x is all real numbers except for x = 0 since the function is undefined at that point.
The Domain is the first coordinate which is x. The Range is the second coordinate which is y.
The domain of the given graph in the image will be calculated as,
0 < x ≤ 5
Therefore, the correct option is A.

If EF = 6 and EG = 23, find the value of FG.
Answer:
FG=138
Step-by-step explanation:
Since 23 is a prime number, the only factors of it are 1 and 23.
Which means E is either 1 or 23.
Since 23 is not a factor of 6, E=1. Therefore, G= 23. And, F=6.
So, FG=23*6, which means FG=138.

2 factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Two percent of the panels from Plant A and 5% of the panels from Plant B we’re defective. How many panels did Plant B produce, if the two plants together produced 1140 defective panels
Answer:
Number panels Plant B produce = 18,000
Step-by-step explanation:
Given:
Plant produces defective panels = 1140
Plant B produce = 5%
Plant A produce = 2%
Find:
Number panels Plant B produce
Computation:
Assume
Number panels Plant B produce = x
Number panels Plant A produce = x - 6000
So
5%(x) + 2%(x-6000) = 1140
0.05x + 0.02x - 120 = 1140
0.07x = 1260
x = 18,000
Number panels Plant B produce = 18,000

Explanation:
This is a piecewise function. It's composed of 3 pieces of other functions. A piecewise function is a function that changes its identity based on what the input is.
We have three different situations here
If t = 17, then h(t) = sqrt(17t) based on what the first row saysIf t = 19, then h(t) = -34/t which is the second row of the piecewise function.If t does not equal either 17 or 19 (ie t is anything but those values), then h(t) = 23-tThe notation h(17) means we want to evaluate h(t) when t = 17. So we'll use the first case mentioned above. Plug t = 17 into h(t) = sqrt(17t) to get...
h(t) = sqrt(17t)
h(17) = sqrt(17*17)
h(17) = sqrt(17^2)
h(17) = 17
In the last step, I used the rule that sqrt(x^2) = x when x is nonnegative.

A company is looking to hire a lawyer. One law firm states that their legal fees can be determined using the expression 350x + 22,000, where x is the number of hours of legal assistance. A second law firm states that their legal fees can be determined using the expression 410x+16,000. The company president wants to know when the legal fees would cost the same for each law firm. What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?
Answer:
100 hours
Step-by-step explanation:
The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
We have,
Two expressions that denoted the legal fees for x hours:
350x + 22,000 ____(1)
410x+16,000 _____(2)
Where x = number of hours
The number of hours where both the legal fees are equal:
350x + 22,000 = 410x + 16,000
Subtract 350x on both sides.
22,000 = 410x -350x+ 16,000
22,000 = 60x + 16,000
Subtract 16,000 on both sides.
22,000 - 16,000 = 60x
6,000 = 60x
Divide both sides by 60.
x = 100
Thus,
The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.

Alessandra is raising turtles and must keep the air temperature in their enclosure at 32. C , with a relative error less than 3%. Write an absolute value inequality for the actual temperature
The absolute value inequality for the temperature T is:
|T - 32°C| < 0.96°C
How to write the absolute value inequality?
The general way of writing these inequalities is:
|variable - average value| < accepted error.
Here the variable is the temperature so we can use T for it.
The average is 32°C, and the accepted error is less than 3%, so it is:
0.03*32°C = 0.96°
Then the absolute value inequality will be:
|T - 32°C| < 0.96°C
Where it means that the temperature will be at less of 0.96°C of the 32°C.
