Answer:

$L = 80 - 8t$

Step-by-step explanation:

Given

$Debt = \$80$

$Weekly\ Payment = \$8$

Required

Write an equation to determine the payment at a given week

At week 1, she'd have paid $8

At week 2, $16

Week 3, $24

This leads to arithmetic progression (AP):

8, 16, 24.....

To further solve, we'll make use of AP formula

$T_n = a + (n - 1)d$

In this case;

$t = n$

$d = 16 - 8 = 24 - 16 = 8$

$a = 8$

So, the equation becomes

$T_n = 8 + (t - 1) * 8$

$T_n = 8 + 8t - 8$

Collect Like Terms

$T_n = 8t + 8 - 8$

$T_n = 8t$

The above represents the amount paid at a particular week;

Amount owed, L is then calculated as follows;

$L + T_n = 80$

$L = 80 - T_n$

$L = 80 - 8t$

I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t

igomit [66]

Answer:

The tax on property assessed at $660,000 is $13860 .

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, we need to get the tax rate of Atlanta first.

Tax Rate = Tax / Property assessed × 100.

$Tax\ rate=\frac{19530}{930000} \times 100$

$Tax\ rate=0.021 \times 100$

$Tax\ rate=2.1\%$

According to question the tax rates are proportional.

So, for getting the tax in this city we use the same rate of Atlanta:

Tax = tax rate of property assessed.

$Tax = 2.1\% of\ \$660,000$

$Tax = \frac{2.1}{100}\times 660000.$

$Tax = 0.021\times 660000$

$Tax=\$13860$

Therefore, the tax on property assessed at $660,000 is $13860.

A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?

Bumek [7]

Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft
