March 15 balance: 56.75
Add: Deposit x
Less: Outstanding check 18.25 ⇒ 5 + 13.25
March 20 balance: 87.37
56.75 + x - 18.25 = 87.37
x = 87.37 - 56.75 + 18.25
x = 48.87 CHOICE D.
Outstanding checks are issued checks that are not yet deducted from the account.
X/35 = 7
we can multiply 35 on both sides
x = 245
Ok equilateral triangle
altitude=27
height=27
if you drwa the height, you see that the equilateral triangle is split up into 2 right trnalges
base=1/2 of one side
hypotonuse=1 side
vertical side=27
represent measure of 1 side as x
base=x/2
hypotonuse=x
vertical side=27
we have a right triangle
use pythagoran theorem
a^2+b^2=c^2
a=x/2
b=27
c=x
so
(x/2)^2+27^2=x^2
(x^2)/4+729=x^2
multiply both sides by 4 to clear fraction
x^2+2916=4x^2
subtract x^2 fromboth sides
2916=3x^2
divide both sides by 3
972=x^2
squuare root both sides
18√3
one side is 18√3 feet or aprox 31.1769 feet
