Step-by-step explanation:

9^8/9^2 ➡ 9^8-2 = 9^6 to divide this expression we subtract the bottom number from the top number

5^2 × 5^3 ➡ 5^2×3 = 5^6 to multiply this expression we multiply the powers

1. Write an algebraic expression for the word phrase ; the quotient of r and 12.

oksano4ka [1.4K]

r ÷ 12 or r/12

<h3>Further explanation</h3>

Given the word phrase: the quotient of r and 12.

An algebraic expression for it is $\boxed{ \ r \div 12 \ or \ r/12 \ or \ \frac{r}{12} \ }$

<u>Notes:</u>

The quotient is the ratio of two quantities to be divided or the number obtained by division. Synonyms for the quotient are proportion, ratio, or fractions.

An algebraic expression for the quotient of a and b is $\boxed{ \ a \div b \ or \ a/b \ or \ \frac{a}{b} \ }$

'a' is called a dividend
'b' is called a divider
The quotient is the result derived after dividing the dividend by the divisor.

The quotient, a dividend, and a divisor represent the fundamental components of a division equation.

<u>Another example:</u>

A car requires 10 liters of fuel to travel 60 km. Determine the quotient of the distance of the car with fuel (in km/L).

The quotient (or ratio) is

$\boxed{ \ the \ distance \div fuel \ consumption \ }$

$\boxed{ \ 60 \ km \div 10 \ L \ }$

$\boxed{\boxed{ \ 6 \ km/L \ }}$

Consider the same method as follows.

$\boxed{ \ \frac{the \ distance}{fuel \ consumption} \ }$

$\boxed{ \ \frac{60 \ km}{10 \ L} \ }$

$\boxed{\boxed{ \ 6 \ \frac{km}{L} \ }}$

This means that the car can travel a distance of 6 km for every 1 L of fuel.

Kilometers per liter is a unit used to measure fuel economy and we see this as one example of the use of the quotient (or ratio).

Alina has to spend $30 000 on expenses each year. If that amount of money is 40% of her total yearly earnings, then how much mon

BaLLatris [955]

Answer:

$75000

Step-by-step explanation:

Given data

Let her yearly earnings be x

40% of x= $30000

40/100*x=30000

0.4x=30000

x=30000/0.4

=$75000

Hence the total amount made per years is

$75000

Attached is the problem, if anyone could help me and explain this I would be grateful.

Kryger [21]

Let's say that, that equals some angle θ
thus $\bf sec^{-1}(1)=\theta \iff sec(\theta)=1\\\\
-----------------------------\\\\
sec(\theta)=\cfrac{1}{cos(\theta)}\qquad thus\\\\
-----------------------------\\\\
\cfrac{1}{cos(\theta)}=1\implies \cfrac{1}{1}=cos(\theta)\implies 1=cos(\theta)
\\\\\\
\textit{now, taking }cos^{-1}\textit{ to both sides}
\\\\\\
cos^{-1}(1)=\theta$

so.. .check your Unit Circle, what is that angle anyway?
