Answer:$24

Step-by-step explanation:

To find 20 percent of a number you multiply the number by 20, then multiply the answer by .01.

120 x 20 = 2400

2400 x .01 = 24

In the equation, t is a constant. If the equation has no real solutions, what could be the value of t? 2x^2 − 4x = t please help

swat32

2x^2-4x=t

2x(x-2)=t

if t=0:

0=2x(x-2)

$\frac{0}{2(x - 2)} = x$

so, x=0

if t is not=0:

$x = \frac{t}{2(x - 2)}$

If A is the set of prime numbers and B is the set of

Natasha2012 [34]

The correct option is (A) None.

The numbers of digits that are common to both sets is none.

In mathematics, a set is a group of distinct objects that form a group. A set can contain any type of group of items, such as a grouping of numbers, days of the week, vehicle types, and so on.

Each element inside the set is referred to as a set element. When writing a set, curly brackets are used.
A simple instance of a set could be as follows. Set A = {1,2,3,4,5}. A set's elements can be represented in a variety of ways.
A roster form or even a set builder form is typically used to represent sets.

Now, according to the question;

Set A = {1,3,5,7,11,13,17,19,......} Prime Number Collection (The numbers which have only two factors i.e, 1 and the number itself)

Set B {15,25,35,45,55,......} Set of two-digit positive integers with the unit digit ("5").

Each two-digit positive integer with such a unit digit of 5 has much more than two factors; Set B has 1,5 as well as "itself" as factors.

As a result, these two sets are disjoint sets (no common element).

HELP PLEASE!! Which of the following best describes the graph below? A. it us a one-to-one function B. it us a function but it i

masha68 [24]

The correct statement regarding the function $y = \sqrt{x + 2}$ is given by:

A. it us a one-to-one function.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on the internet, the function used is $y = \sqrt{x + 2}$ .

<h3>Is it a function?</h3>

For $y = \sqrt{x + 2}$ , each value of x is associated with only one value of y, that is, the graph has <u>no vertically aligned points</u>, hence it is a function.

<h3>Is the function one-to-one?</h3>

Each value of y is also associated with only one value of x, that is, the graph has <u>no horizontally aligned points</u>, hence it is a one-to-one function, and the correct statement is given by:

A. it us a one-to-one function.
