Answer:
Step-by-step explanation:
4/(2+4+8+2) = 4/16 = 1/4
Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
y + 3y + y + 30 + 90 = 360 , that is
5y + 120 = 360 ( subtract 120 from both sides )
5y = 240 ( divide both sides by 5 )
y = 48
3y = 3 × 48 = 144
y + 30 = 48 + 30 = 78
The measure of the 4 angles are
48°, 78° , 90° , 144°
It is 3f - 9
So you multiply f by 3 and subtract 9
As simple as that!
Answer: The balance in the account increases at a rate of 2.5%
Step-by-step explanation:
The balance in the account after x years is modeled by
b (x) = 850(1.025)x
In another form
b(x) = 850(1 + 25%)^x
Where
850 = initial deposit
25% = Interest rate
"+" sign signifies the increase
Therefore the balance in the account increases at a rate of 2.5%
This is placed at the thousandth place
(i think that is what you wanted me to answer..?)
hope that helps :)
