Answer:
When we divide 50 by 100 we get 0.5 (a decimal number). So, to convert from percent to decimal: divide by 100, and remove the "%" sign.
Answer:
To convert a decimal to a percentage, multiply by 100 (just move the decimal point 2 places to the right).

An airplane cuts through the morning sky. For every 1,000 feet that it climbs, the outside temperature drops 20 degrees Fahrenheit. What is the rate of temperature change in degrees Fahrenheit per foot? Complete the steps below to answer the question.
part A: Write the change in elevation and the change in temperature as rational numbers.
part B: Write a numerical expression to represent the rate of temperature change in degrees Fahrenheit per foot.
part C: What is the rate of temperature change in degrees Fahrenheit per foot?
part D: Now, consider the reverse situation: as the airplane descends, or drops, 1,000 feet in the air, the temperature rises 20 degrees Fahrenheit. Write a numerical expression representing the rate of temperature change in degrees Fahrenheit per foot.
part E: What is the rate of temperature change in degrees Fahrenheit per foot?
part F: How is the rate you found in part E related to the rate you found in part C? What does this mean?
I've been stuck on this for so long and I think today is my last day to finish it and I haven't been able to concentrate or focus all day
Answer:
Step-by-step explanation:
part A=The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.
Part B= -20 degrees fehrenheit/1,000 feet
Part C= -20 degrees fehrenheit/1,000 feet= -1 degrees fehrenheit/50 feet
The answer can also be written as -1 degrees fehrenheit/50 per foot.
Part D = The airplane is descending, so the change in elevation is -1,000 feet. The temperature is rising, so the change in temperature is +20 degrees Fahrenheit.
The rate of temperature change in degrees Fahrenheit per foot is 20/-1000
Part E= The answer can also be written as-1/-50
Part F= The rate in part E is equal to the rate in part C. It means that -1/50=1/-50=-1/-50

Hannah estimates the ribbon is 100 cm long. The actual length of the ribbon is 125 cm. What is the percent error of Hannah's measurement?
Answer: -20
percent error= amount of error/actual value * 100
amount of error= 100-125= -25
percent error = -25/125 *100
percent error= -20
The percent error of Hannah's estimate will be 20%.
Hannah estimates the ribbon's length to be 100 cm. The ribbon's real length is 125 cm.
How to calculate the percent error?To find the percent error of Hannah's estimate, we need to first calculate the difference between the estimated value and the actual value.
In this case, the difference is 125 cm - 100 cm = 25 cm.
Now we can divide the difference by the actual value and multiply by 100% to find the percent error.
As per the given question, the percent error is :
⇒ (25 cm / 125 cm) x 100%
⇒ 0.2 x 100%
⇒ 20%.
Therefore, the percent error of Hannah's estimate will be 20%.

Abby and Alex were practicing free throws. Abby attempted 40 shots and made 36 of them. Alex attempted 60 shots and made 54 of them. Who made a higher percentage of their attempts?
Answer:
Abby is the answer
Step-by-step explanation:
When you calculate Abby’s free throws you should realize
40 - 36 = 4
However with Alex’s free throws you calculate
60 - 54 = 6
When you compare the two Abby has a higher percentage of attempts because she was more successfu!

9514 1404 393
Answer:
9
Step-by-step explanation:
Let x and y represent the two numbers, with y being the smaller.
x - y = 6 . . . . . . difference is 6
3x = 5y . . . . . . . 3 times the larger is 5 times the smaller
Use the first equation to write an expression to substitute for x:
x = y + 6
3(y +6) = 5y
18 = 2y . . . . . . .subtract 3y and collect terms
9 = y
The smaller number is 9.

Nevan’s gross pay was $45,150 last year. The federal income tax withholding from his pay was 16% of his gross pay. Nevan determined the federal income tax he owes is $6,150. Which of the following is true?
Nevan owes an additional $984 in federal tax.
Nevan owes an additional $1,074 in federal tax.
Nevan will receive a refund of $984.
Nevan will receive a refund of $1,074.
Nevan owes an additional $1,074 in federal tax.
What is federal tax?" Federal tax is tax which is imposed by United state government on annual earning."
According to the question,
Nevan's gross pay = $45,150
Percentage of federal income tax on his gross pay = 16%
Federal income tax = [tex]45,150[/tex] × [tex]\frac{16}{100}[/tex]
= $ 7,224
Federal income tax Nevan's owes = $6,150
Additional federal tax Nevan's owes = [tex]7,224 -6,150[/tex]
=$1,074
Hence Nevan owes an additional $1,074 in federal tax.

Engineers measure angles in gradients, which are smaller than degrees. The table shows the conversion of some angle measures in degrees to angles in gradients. What is the slope of the line representing the conversion of degrees to gradients?
Express your answer as a decimal rounded to the nearest hundredth.
Answer:
1.11
Step-by-step explanation:
The slope of the line representing the conversion of degrees to gradients is 1.11.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
Engineers measure angles in gradients, which are smaller than degrees.
The formula for the slope:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Taking two points (-180, -200) and (-90, -100)
[tex]\rm m =\dfrac{-100-(-200)}{-90-(-180)}[/tex]
m = 100/90
m = 1.11
Thus, the slope of the line representing the conversion of degrees to gradients is 1.11.

Step-by-step explanation:
1. If it takes 1 hour to travel 48 miles, then you can subtract it from the 60 miles, and have 12 miles left. Divide 12 by 48, and you get 0.25, so if you add it together, you get 1.25. To check, 48 x 1.25 equals 60.
2. 270 minutes is equal to 4.5 hours. Divide 63 by 4.5, and you'll get 14 miles per hour. To check, 4.5 x 14 equals 63.
