sammy [17]

Answer:

See explanation

Step-by-step explanation:

cos(θ)= 18/30 = 3/5

sin(θ)= 24/30 = 4/5

tan(θ)= 24/18 = 4/3

cos(ϕ)= 24/30 = 4/5

sin(ϕ)= 18/30 = 3/5

tan(ϕ)= 18/24 = 3/4

Dvds are for $24 each,felipe write the expression 4 times 24 to find the costin dollars of buying 4 dvds, how can i rewrite feli

Karo-lina-s [1.5K]

The distributive property states that:

a(b+c)=ab+bc.

or more generally: a(b+c+d)=ab+av+ad.

This is a very useful tool to perform multiplication.

For example, if we want to multiply 7 by 234, we can proceed as follows:

7*234=7(200+30+4)=7*200+7*30+7*4=1400+210+28=1610+28=1638

back to our problem,

4 * 24 = 4(20+4)=4*20+4*4=80+16=96 ($)

So, instead of multiplying 4 by 24, we multiplied 4 by 20 and 4, which is easier, and then added these together.

Answer:

4 * 24 = 4(20+4) [=4*20+4*4=80+16=96 ($)]

Is 50.2 a rational or an irrational number, why?

Greeley [361]

Answer:

Rational.

Step-by-step explanation:

$\textbf{A rational number is a real number that can be expressed as}~ \dfrac{p}{q},\\\\\textbf{where}~ p~ \textbf{and}~ q~ \textbf{are integers.}\\\\ \boxed{50.2 = \dfrac{502}{10}}\\\\ \textbf{50.2 can be expressed as a ratio of two integers,}~ \textbf{so it is a rational number.}$
