adding a negative number is the same as subtracting a positive number. This question is the same as 10.5-8.3
Answer:
Room and board
30%
Step-by-step explanation:
If you look at the numbers in the table, you can easily see Room and board is the largest expense, with $127.50, three times more than the second place.
Now, to find the percent of that expense vs her income we just have to divide this big expense ($127.50) by the total income she has ($425).
% = $127.50 / $425 = 30%
So, that expense is 30% of her income, that's a big chunk, but it's normal for lodging expenses.
Answer:
A,C,D
Step-by-step explanation:
The general formula for the equation of the straight line is:
y−b=m(x−a) where
m is the slope
a is the x coordinate of the given point
b is the y coordinate of the given point
The slope is given as 2
x coordinate in the given point is 5
y coordinate of the given point is 9
Substitute with these values in the mentioned equation as follows:
y−9=2(x-5)
Answer:
530.998cm^2
Step-by-step explanation:
General formula for the area of a circle is πr^2
And π is given to be 3.142
R is 13 cm
So let's apply the formula
Area=3.142×(13^2)
Area=3.142×169
Area=530.998cm^2
So the area of the circle is 530.998cm^2
