95.7942857 pie form hope this is right got it off the internet so yeah
$1 = $20.19 pesos, try dividing 510 pesos by 20.19. That should give you the dollar amount.
X would equal 57 if 52 replaces x then 3+52 is 55 and 55+2 equals 57.
Divide both sides by 35
r-7=1/35
add 7 to both sides
r=7+1/35
r=245/35+1/35
r=246/35
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.
