Yes, for fractions you can multiply the denominator by the numerator. For square roots you can use the square root button.

You can try


well, a number is rational if it can be writtten in form a/b where a and b are integers and b≠0

integers are like -4,-3,-2,-1,0,1,2,3,4


irrational numbers can't be written in form a/b like that with integers

so if we had 2/3, we're done, no need to use calculator
note: all releating deciamals can be written as a fraction and are therefor rational

you can use a calculator, but if it's in fraction form, no need to do that
sometimes a number repeats but you might not be able to see it if you use a calculator

Como repartir 5,20 dolares en cuatro partes iguales?
Tems11 [23]

Answer:

Por ejemplo, podrías utilizar la división para determinar cómo repartir 40 ... 15 ÷ 5 = 3. Podrías también usar la recta numérica para modelar ésta división. ... ¿Cuáles de las siguientes expresiones representan dividir $56 en partes iguales entre 7 ... “5, 10, 15, 20, 25, 30. Debo saltar 6 veces para llegar a 30.” 30 ÷ 5 = 6.

Need help ASAP!!!!!
svetlana [45]

Answer:

cos 45 degree = A/H

cos 45 degree =  2 square root 2 / x

x = 2 square root 2 / cos 45 degree

x = 4

Sin 45 degree = O/H

Sin 45 degree = y/ 4

4 x Sin 45 degree = y

y = 2.83

or

we could use tan

tan 45 degree = O/A

tan 45 degree = y / 2 square root 2

2 square root 2 x tan 45 degree = y

y = 2.83

i hope this would elp a little bit.

Determine sum of the first 16 terms (S16) for an arithmetic series given the first tem is 9 (a = 9) and
Mekhanik [1.2K]

\boxed{Sum=624}

<h2>Explanation:</h2>

The nth term of an arithmetic series (a_{n}) and the sum of an arithmetic series (Sum), for n terms, can be found as:

a_{n}=a_{1}+d(n-1) \\ \\ Sum=\frac{n}{2}[2a_{1}+(n-1)d] \\ \\ \\ Where: \\ \\ a_{1}:First \ term \\ \\ d:Common \ difference \\ \\ n=Number \ of \ term

So, in this exercise:

a_{1}=a=9 \\ \\ d=4 \\ \\ n=16 \\ \\ \\ Sum=\frac{16}{2}[2(9)+(16-1)4] \\ \\ Sum=8[18+(15)4]  \\ \\ Sum=8[18+60] \\ \\ Sum=8[78] \\ \\ \boxed{Sum=624}
