Step-by-step explanation:
30 x .47 = 14.1
Answer:
x = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 9²
x² + 1 = 81 ( subtract 1 from both sides )
x² = 80 ( take square root of both sides )
x =
=
=

= 4
-10x -120-11x
combine like terms so -10-11= -21x-120
Hey!
So we have 6 multiplied by -12 and that is over 10
so we are multiplying a positive number by a negative number. When you do that the answer will be a negative number.
Now we have -72/10
we can simplify that more
divide the numerator and denominator by 2 because that is the largest number that is divisible by both number
now it is -36/5
The answer is -36/5
Hope this helps!
Answer:
309
Step-by-step explanation:
The formula for simple interest is
A = P(1 + rt)
where A is the amount of money in the account
P is the principal invested
r is the interest rate in decimal form
t is the time invested in years
We know
P = 300
r = 4% = .04
t = 9 months = 9 months * 1 year/12 months = .75 year
Substituting into the equation
A = 300(1 + .04*.75)
=300 (1+.03)
=300(1.03)
= 309
