Answer:
$6534.42
Step-by-step explanation:
Put the given values into the simple interest formula and solve for the remaining variable.
A = P(1 +rt)
where P is the principal invested, r is the annual rate, and t is the number of years.
$7000 = P(1 +0.095(9/12)) = 1.07125P
$7000/1.07125 = P ≈ $6534.42
The value that must be invested is $6534.42.
Answer:
8 spools
Step-by-step explanation:
48 divided by 6
Answer:
100
Step-by-step explanation:
M = log(I/S)
The intensity of the first earthquake:
8 = log(I₁/S)
10⁸ = I₁/S
I₁ = 10⁸ S
The intensity of the second earthquake:
6 = log(I₂/S)
10⁶ = I₂/S
I₂ = 10⁶ S
The ratio is:
I₁/I₂ = (10⁸ S) / (10⁶ S)
I₁/I₂ = 100
It is 100 times stronger.
Answer:
Which number is the slope of the line shown by the equation?
B. 40
Which number is the y-intercept
D.75
Step-by-step explanation:
The formula for the Equation of a line =
y = mx+b
where:
m is the slope and b is the y-intercept.
Hence, interpreting the above question:
On a two-week job, a repairman works a total of 70 hours,He charges 75$ plus 40$ per hour.
x is the number of hours and y is the total fee.
Hence, the Equation we have is:
y = $40 × x + 75
y = 40x + 75
Comparing with the Equation of a line formula
= y = mx+b
Therefore:
The slope of the line = 40
The y intercept = 75
