Step-by-step explanation:
Let
x------> represent babysitting hours
y ------> represent tutoring hours
we now that
The system of inequalities that model the scenario is
-----> inequality A
-----> inequality B
The solution is the shaded area between the positive values of x and y
see the attached figure
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
Answer:
? = 110
Step-by-step explanation:
We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.
All angles of a triangle always adds up to 180
Add all the known angles 25 + 45 = 70
Than subtract 180 - 70 = 110
I think what may be confusing is the fact that they also list two three digit numbers with two decimal places each. Since the number is greater than 4.49 with only two digits, it can't be 4.5 since the tenths place is odd. Same goes for less than 4.71. So the only answer would be 4.6--two digits, even tenths place, greater than 4.49 and less than 4.71.
Just some logical thinking, I guess. I think they were trying to trick you on this one.
Good luck.
