Answer:
The balance after 15 year is $831.25 .
Step-by-step explanation:
Formula
Where P is the principle and r is the rate of interest in the decimal form and t is the time.
As given
Caiden earned $475 from mowing lawns last summer.
He deposited this money in an account that pays an interest rate of 3.8% compounded annually.
Here
P = $475
3.8% is written in the decimal form.
= 0.038
r = 0.038
t = 15 years
Put in the formula
Amount = $831.25
Therefore the balance after 15 year is $831.25 .
Answer:
Width is 4cm, length is 12 cm.
Step-by-step explanation:
Write the problem as an equation.
(x+12)*(x)=48
Where x is the length of the shorter side.
Solve.
(x^2)+12x=48
x=4
Answer:
x=31
Step-by-step explanation:
we need to isolate x so we put 48 t the other side to make -x=17-48
we do 17-48 =-31 so -x=-31
x=31
Answer:
Part 1) 11 is a rational number
Part 2)
is a irrational number
Step-by-step explanation:
we know that
A <u><em>Rational Number</em></u> is a number that can be made by dividing two integers
Part 1) we have

we know that

substitute

Is a rational number, because i can express the number 11 as the ratio of two integers (as example 11/1)
Part 2) we have

we know that

substitute

Is a irrational number, because cannot be expressed as the ratio of two integers
The coefficient of the variable......the variable is a letter subbed in for an unknown number.....so the variable is x....the coefficient is the number multiplied by the variable....so that is -5.
