Angle 1&3 is 70° becuase 180-110= 70

Angle 4 is 110° becuase it is the alternate exterior angle to Angle 2, which equals 110°.

Hope this helps!

How is estimation helpful when adding and subtracting decimals?

alex41 [277]

Estimation is always helpful when it comes to math. By estimating, you will have a good idea with what the final answer should be before you actually get it. This way, you will hopefully be able to have a good sense of whether the answer is wrong

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

Setler79 [48]

The A option is correct.

<h2>Ratio and proportion</h2>

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

$\rm P = PV(\dfrac{i}{1-i})^{-n}$

The effect an increase in i.

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\$

on simplifying the equation, we get

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}$

Let n be the constant, then the equation will be

$\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i$

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.

More about the ratio and the proportion link is given below.

Why do we measure capacity what is a real world example

NISA [10]

Hello there,

We measure capacity because it's useful for everything. Capacity, for example, is how much milk do you need in a cake recipe. Without measuring the capacity of milk, it could be too liquidy or too dry.

Hope this helps!
