**Answer 1**

If the **repayment **on a **loan** was **Php 23600**, the **principal amount **is equal to **Php 131,111.11.**

Given the following data:

Interest rate = 12%Simple interest = Php 23600Time = 18 months

Conversion:

12 months = 1 year

18 months = 1.5 year

To calculate the **principal amount** if the **interest rate** is **12%** a **year**:

Mathematically, **simple interest** is given by the **formula**:

[tex]S.I = \frac{PRT}{100}[/tex]

Where:

S.I is the **simple interest**.P is the **principal amount**.R is the **interest rate**.T is the** time** measured in **years**.

Making **P** the subject of **formula**, we have:

[tex]P = \frac{100S.I}{RT}[/tex]

Substituting the given parameters into the **formula**, we have;

[tex]P = \frac{100 \times 23600}{12 \times 1.5}\\\\P = \frac{2360000}{18}[/tex]

**Principal amount**, **P **=** Php 131,111.11**

What is an equation?

An **equation **is a formula that expresses the equality of two **expressions**, by connecting them with the equals sign =

Given that, A **fish **swims 4 feet directly above a scuba **diver**. The **fish **suddenly **dives **to double its depth under the surface of the ocean. The fish **dives **to a depth of −34 feet.

Let the position of the **fish **is at x feet from surface of the ocean

Therefore, the position of scuba diver = x-4

Since, the **fish **dives double its depth, therefore, new position of diver = 2(x-4)

According to question,

2(x-4) = -34

2x-8 = -34

2x = -26

x = -13

Therefore, the position of the **diver **= -13-4 = -17

Hence, the position of the scuba **diver **relative to sea level is 17 feet below surface.

y∝1/√x If y=5

when x=36 find,

x when y=3

### Answers

**Answer:**

**x = 100**.

**Step-by-step explanation:**

y ∝ 1/√x

y = k /√x where k is a constant.

When x = 36 y = 5 so we have:

5 = k / √36

5 = k / 6

k = 30

So we have the relation:

**y = 30 /√x **

When y = 3

3 = 30/ √x

√x = 30/3 = 10

**x= 100**.
