Answer:
The value of the given expression is 84.
Step-by-step explanation:
The given expression is
![\frac{252}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B252%7D%7B3%7D)
The number 252 can be written as 240+12, because 24 can easily divisible by 3.
The compatible numbers are 240 and 12
![\frac{252}{3}=\frac{240+12}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B252%7D%7B3%7D%3D%5Cfrac%7B240%2B12%7D%7B3%7D)
![\frac{252}{3}=\frac{240}{3}+\frac{12}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B252%7D%7B3%7D%3D%5Cfrac%7B240%7D%7B3%7D%2B%5Cfrac%7B12%7D%7B3%7D)
![\frac{252}{3}=80+4](https://tex.z-dn.net/?f=%5Cfrac%7B252%7D%7B3%7D%3D80%2B4)
![\frac{252}{3}=84](https://tex.z-dn.net/?f=%5Cfrac%7B252%7D%7B3%7D%3D84)
Therefore the value of the given expression is 84.
Answer:
Hailey's distance from home
Step-by-step explanation:
as time passes, the y value get ssmaller and smaller. ultimately becoming zero.
for the first option, if she is riding her bike away from school, her distance from school would not be getting smaller and smaller
the height of the tree would not be getting shorter and shorter
the number of students on a bus would be increasing on the way to school
however, as hailey approaches her house, her distance from the house would be getting smaller
Answer:
Step-by-step explanation:
Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.
If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;
Note that the function can either be negative or positive because of the modulus sign
If x = 0.5
For positive value,
f(0.5) = 98.6-0.5
f(0.5) = 98.1
If the function is negative
f(0.5) = -(98.6-0.5)
f(0.5) = -98.6+0.5
f(0.5) = -98.1
The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1
