PERCENT means parts out of 100 so

What s an equivalent fraction to 70/80

Answers

An equivalent fraction is a fraction where its numerator and denominator are multiplied by the same constant factor. If the fraction can be simplified more, then the equivalent fraction simplified is also an equivalent fraction.

Some equivalent fractions for $(70)/(80)$ are $(7)/(8) , (140)/(160) , (14)/(16) , (210)/(240) , (21)/(24), ...$ and so on.

Hope that helps :)

What number should be added to the expression x^2 + 4x to change it into a perfect square trinomial?

Answers

x^2 + 4x
the number to be added is found by dividing the constant of x by 2
and squared the number
so # to be added = ( 4/2)² = 4
the perfect square trinomial is
x² + 4x + 4 = (x + 2 )² which is a perfect square trinomial
I hope this help you

he number that must be added is four because (x+2)^2=x^2+4x+4

Write all names that apply to 121/√121

Answers

Answer:

Natural, Whole, integer, rational, real

Step-by-step explanation:

Here, the given number,

$(121)/(√(121))$

We can write,

$(121)/(√(121))=(121)/(11)$

∵ 121 and 11 are integers also, 11 ≠ 0,

So, $(121)/(11)$ is a rational number,

⇒ $(121)/(√(121))$ is a rational number,

Now,

$(121)/(11)=11$

11 is a whole number,

⇒ $(121)/(√(11))$ is a whole number,

Again, a whole number is always a natural number and a positive integer ,

⇒ $(121)/(√(11))$ is a natural number or an integer,

All numbers ( rational or irrational ) are called real number.

So, we can also write,

$(121)/(√(121))$ is a real number.

type it in the calculator and there is your answer

your bag`s weigh is 22 pound right now so you still can add 40 - 22 = 18 pounds. So you can right this inequality:
x + 22 ≤ 40
so x is the number of pound that you can add:
x ≤ 40-22
x ≤ 18 :)))
