Answer:
Step-by-step explanation:
The formula for simple interest is
I = Prt,
where I is the interest earned,
P is the initial investment amount,
r is the interest rate in decimal form, and
t is the time in years. For us,
I = 75,
P = ?
r = .05
t = 1
Filling in what we were given:
75 = P(.05)(1) and
.05P = 75 so
P = 1500
ANSWER= 30 rides
STEP-BY-STEP EXPLANATION
y=mx+b
m= $0.5 (per ride)
b= $5 (the cost)
x(rides) and y(parents money)
y= 0.5 x + 5
20= 0.5 x +5
20 - 5 = 0.5 x
15=0.5x
x=
x=30 rides
The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)
<h3>What is an expression?</h3>
An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division
x^3 – 7x^2 – 5x + 35
factor the given equation
x^2(x – 7) – 5(x - 7)
Factor out x - 7
(x^2 - 5)(x - 7)
Therefore, the factored expression is (x^2 - 5)(x - 7)

To
get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do
this, we will get 20.70, which means that 20.70 milliliters of alcohol were
used. On the other hand, we can get the milliliters of water used through two
ways: the first one is by simply subtracting 20.70 from 690, which will give us
the answer 669.30. Another would be by multiplying 690 by 0.97, which will also
yield the answer 669.30. The number of milliliters of water used was 669.30.
