Find the value of x if (1.1)^x=100

iragen [17]

Answer:

x ≈ 48.3177

Step-by-step explanation:

This is what logarithms are for (among other things).

log(1.1^x) = log(100)

x·log(1.1) = 2

x = 2/log(1.1) ≈ 48.3177

Write and solve an equation for the following word problem. Define your variable.

marshall27 [118]

Answer:

The variable is the number of clothes sold 'x'.

The equation is: $118.50=100+0.25x$

The number of clothes sold by Lynn are 74.

Step-by-step explanation:

Let the number of pieces of clothes sold be 'x'.

Given:

Earning of Lynn per cloth is $0.25.

Fixed earning of Lynn per day is $100

Total earning after selling 'x' clothes is $118.50.

Variable: Number of clothes 'x'.

Equation:

Earning of Lynn for 1 cloth = $0.25

∴ Earning of Lynn for 'x' clothes = $0.25\times x=0.25x$

Now, total earning of Lynn is the sum of fixed earning and earning from selling 'x' clothes. Therefore,

Total earning = Fixed earning + Earning for 'x' clothes

⇒ $118.50=100+0.25x$

Solution:

Add -100 both sides and then divide the result by 0.25 both sides. This gives,

$118.50-100=100-100+0.25x\\0.25x=18.50\\x=\frac{18.50}{0.25}=74$

Therefore, the number of clothes sold by Lynn are 74.

Congruence Properties

In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!

The Reflexive Property of Congruence

The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
