Answer:
The missing information is attached in the picture below.
The company made $292.5 dollars in profit.
Step-by-step explanation:
Using the information provided by the table, we can calculate how much money was spent
1. gravel
12 and a half cubic yards * $15 = $187.5
2. tar/sealant
$0.15 per square foot * (75*20 ft^2) = $225
3. labor
$10 per hour * 25 hours = $250
4. insurance
fixed $45
We add all the expenses together
$(187.5 + 225 + 250 + 45) = $707.5
The profit will be equal to
$1000 - $707.5 = $292.5

Answer:
Hey there!
There are 13 clubs in a deck of cards.
There are 4 tens.
However, the tens overlap with the clubs, so there are 16 cards to choose.
16/52=4/13

Answer:
10 inches
Step-by-step explanation:
The formula for the triangle area is the following:
A = b * h / 2
Where b is the length of the base side and h is the height.
So, as the height is 4 less than the base, we have that:
h = b - 4
Using this value in the area equation, we have that:
A = b * (b - 4) / 2
30 = (b^2 - 4b) / 2
b^2 - 4b = 60
b^2 - 4b - 60 = 0
Using Bhaskara's formula to solve the quadratic equation, we have:
Delta = 4^2 + 4*60 = 256
sqrt(Delta) = 16
b1 = (4 + 16)/2 = 10
b2 = (4 - 16)/2 = -6 (negative value does not fit for this problem)
So the length of the base is 10 inches.
