What are two numbers that when multiplied equal -30 and when added together equal 1?

Answers

Answer:

5 and 6

Step-by-step explanation:

-5 x 6 = -30

-5 + (6) = 1

x2 + 1x - 30 = 0

(X - 5 ) (X + 6)

To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:

x2 + 1x - 30 = (X - 5 ) (X + 6)

The answer is 6 and -5

In a marketing survey involving 1,000 randomly chosen people, it is found that 630 use brand P, 420 use brand Q, and 210 use both brands. How many people in the survey use brand P and not brand Q?

Answers

By Set theory, 420 many people in the survey use brand P and not brand Q.

What is Set theory?

The mathematical concept of sets, which are well-defined collections of things that are referred to as their members or elements, is known as set theory. As only sets are the subject of pure set theory, the only sets that are taken into account are those whose members are also sets.

                               The major reason why set theory is significant is because it offers the axioms upon which the rest of mathematics is constructed. We study sets and their characteristics in the area of mathematical logic known as set theory. A collection of items or a group of items is referred to as a set. These items are frequently referred to as elements or members of a set.

P use = 630 people

Q use = 420 people

both P&Q use ie P∩Q = 210 People

use brand P but not brand Q = P/ P∩Q

                                               = 630 - 210

                                             = 420

Grogg skips count by 5 starting at x. The sum of the first 5 numbers he says is 65. What is the value of x?

Answers

Answer: 11

Step-by-step explanation:

Let the 5 numbers be x,x+1,x+2,x+3 and x+4.

Therefore,

x + x+1 + x+2 + x+3 + x+4 = 65

5x + 10 = 65

5x = 65 - 10

5x = 55

x = 55/5

x = 11

Therefore, the 5 numbers are 11, 12, 13, 14 and 15.

The first number is 11

Step-by-step explanation:

The volume of bed of dump truck :

From the dimension given in the attached picture ;

Volume of bed = 4 ft * 8 ft * 6 ft = 192 ft³

This means dump truck can convey 192 ft³ of salt per trip

Number of trips required to convey 800 ft³ of salt :

800 ft³ / 192 ft³

= 4.166

-10 + 15xy = 20 Direct and inverse variation. constant of variation (k)​

Answers

Answer:

This is an inverse variation, and the constant of variation is k = 2.

Step-by-step explanation:

Direct variation is something like:

y = k*x

Where k is the constant of variation.

So as x increases also increases y.

Inverse variation is something like:

y = k/x

k is the constant of variation.

In this case, if x increases, y decreases.

Now let's look at the equation:

-10 + 15*x*y = 20

Let's isolate y in one side of the equation:

15*x*y = 20 + 10 = 30

15*x*y = 30

y = 30/(15*x) = (30/15)/x = 2/x

y = 2/x

Then we can conclude that this is an inverse variation, with a constant of variation equal to 2.
