Answers

Answer 1

The factors of the quadratic equation are (2x + 5)(2x + 5).

What are factors?

If (x – α) is the common factor of the given quadratic equations then, x = α becomes the root of the corresponding equation.

Given

The quadratic equation is;

[tex]\rm 4x^2+20x+25\\\\[/tex]

The factors of the equation are;

[tex]\rm 4x^2+20x+25\\\\4x^2+ 10x+10x+25\\\\ 2x(2x+5)+5(2x+5)\\\\(2x + 5)(2x + 5)[/tex]

Hence, the factors of the quadratic equation are (2x + 5)(2x + 5).

Answers

Answer: 40,320

Step-by-step explanation:

By Permutation,

The number of arrangements for n things is given by n!.

[Here order matters]

Given: Number of people will give a presentation in class  =8

Then, the number of different orders = 8!

= 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 40320

Hence,  the number of different orders = 40,320

Answers

While making a perfect square for the given quadratic equation [tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex] the value of c is 9/4

It is given that the quadratic equation  [tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex] while forming the perfect square.

It is required to find the value of c.

What is a quadratic equation?

It is defined as the equation of polynomial of degree two. The standard form of the quadratic equation is as follows:

[tex]\rm ax^2+bx+c=0[/tex]  where [tex]\rm a\neq 0[/tex]

We have a quadratic equation:

[tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex]

We know that we can make any quadratic equation into a perfect square by the perfect square trinomial method as follow:

[tex]\rm ax^2+bx+c=0\\\rm ax^2+bx=-c\\\rm ax^2+bx+(\frac{b}{2a})^2 =-c+(\frac{b}{2a})^2\\[/tex]

So, the value of 'c' would be:

[tex]\rm c=(\frac{b}{2a})^2\\[/tex]  here b=3 and a=1 by comparing the equation to the standard equation.

[tex]c=(\frac{3}{2\times1} )^2\\c=(\frac{3}{2} )^2\\c=\frac{9}{4}[/tex]

Thus,  while making a perfect square for the given equation the value of c is 9/4

Bus A stops at a certain bus stop every 25 minutes. Bus B stops at the same stop every 40 minutes. If both buses are at the bus stop at 9:30 a.m., when is the next time they will be there together again? A. 12:20 p.m. B. 12:50 p.m. C. 1:10 p.m. D. 1:30 p.m.​

Answers

Basically we are finding the least common multiple of 40 & 25:

25 : 1,25,50,75,100,125,150,175,200

40: 1,40,80,120,160,200

They will meet again after 200 minutes.

[tex]x = \frac{200}{60} = 3 + \frac{20}{60} [/tex]

So they will meet again after 3 hours and 20 minutes;

9:30 + 3:20 = 12:50 p.m.

That's your answer

The next time where both bus A and bus B are together at a stop is

12:50 pm.

Given,

Bus A stops at a certain bus stop every 25 minutes.

Bus B stops at the same stop every 40 minutes.

If both buses are at the bus stop at 9:30 a.m.

We need to find when is the next time they will be there together again.

How many minutes in one hour?

1 hour = 60 minutes.

Find the total minutes traveled by bus A after 8 stops.
We have,

1 stop = 25 minutes

Multiplying by 8 on both sides.

8 x 1 stop = 8 x 25 minutes

8 stops = 200 minutes

We see that at the 8th stop bus A has traveled for 200 minutes.

Find the total minutes traveled by bus B after 5 stops.
We have,

1 stop = 40 minutes

Multiplying both sides by 5.

5 x 1 stop = 5 x 40 minutes

5 stops = 200 minutes

We see that at the 5th stop bus B has traveled for 200 minutes.

We can say that after 200 minutes of traveling each bus has stopped at the same place.

We have,

Both buses are at the bus stop at 9:30 a.m.

So,

60 minutes = 1 hour

200 minutes

= 60 minutes + 60 minutes  + 60 minutes  + 20 minutes

= 3 hours 20 minutes

So,

9:30 am + 3 hours 20 minutes

= 12:50 pm

Thus the next time both the buses are together is 12:50 pm.

The quotient of the number given number  7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline is 7.

What is the quotient?

Quotient is the resultant number which is obtain by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The number StartFraction 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline EndFraction, given can be written as,

[tex]\dfrac{7^{-1}}{7^{-2}}[/tex]

Let the quotient of this division is n. Therefore,

Step-by-step explanation:

Answer:

-1.4

Step-by-step explanation:

substitute 10 and -3y

so it should look like -3y=10-5.8

then simplify so its -3y=4.2

divide both sides by -3 and you get y = 4.2/-3

multiply both the numerator and denominator by 10 and you get                  y= 42/-30

reduce the fraction to lowest terms by extracting and canceling out 6.

you end up with - 7/5 which simplifies to -1.4 so y = -1.4

A teacher has a treats bag with eleven different types of candy/chocolate inside. What is the minimum number of pieces of candy must be taken to ensure that two of the same pieces of candy are picked?

Answers

The minimum number of pieces of candy must be taken to ensure that two of the same pieces of candy are picked is 12.

How to find the minimum number?

So obviously, there is the case where with only two draws you can get the same candy twice, but we need to find a number N such that we know for sure that always that we take N candy, we drew at least one pair of equal candy.

There are 11 types of candy in the bag.

Now, suppose the next thing.

First, you draw a candy, now there are 10 types of candy in the bag that are different than the one you got.

Now you draw again, and get a different candy, so now there are 9 types of candy in the bag different to the two you got.

Now you keep doing this and getting a different type of candy until you already have the 11 types of candy in your hands.

Now if you draw a candy again, one pair will be formed (because you have all the types of candy already).

From this, we can conclude that always that you draw 12 pieces of candy, at least one pair will be formed.
