Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C
ANSWER

Answer:
Angle 7 and angle 15
Step-by-step explanation:
- <em>Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.</em>
Alternate interior angles with angle 9 are:
<u>Transversal s, parallel lines are t and u,</u>
- Angle 9 is in pair with angle 7
<u>Transversal u, parallel lines are s and r,</u>
- Angle 9 is in pair with angle 15
Answer:
children = 177, adults =215
Step-by-step explanation:
im too lazy to write but solve this with a systeme
x(children),y(adults)
x+y=392
x=392-y
2.5y+1.25x=758.75
2.5y+1.25(392-y)=758.75
2.5y+490-1.25y=758.75
490+1.25y=758.75
1.25y=758.75-490
1.25y=268.75
y=268.75/1.25
y=215
x=392-215=177(number of kids)
