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

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,

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

A number in numerator of a fraction with negative exponent can be written in the denominator with the same but positive exponent and vise versa. Therefore,

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

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

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.

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

Step-by-step explanation:

-5/18  - ( -1/4)

Subtracting a negative is like adding

Getting a common denominator of 36

-5/18 *2/2 + 1/4 *9/9

-10/36 + 9/36

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

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.

Answer:

y = 14

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

Answer:

0.32km

Step-by-step explanation:

The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot , where S is the speed in kilometers per hour and d is the average depth of the water in kilometers.

This is written mathematically as:

S = 356√d

What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour?

S = 200km/hr

Hence:

200km/hr = 356√d

Divide both sides by 356

200/356 = 356√d/356

√d = 200/356

Square both sides

(√d)² = (200/356)²

d =(0.5617977528)²

d = 0.3156167151km

Approximately = 0.32km

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.

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.
