what is -15 plus 22 please answer

Answer:

78,624,000 license plates

Step-by-step explanation:

For each of the 4 numbers, we have the following possibilities:

First number: 10 digits possible

Second number: 9 digits possible (one used)

Third number: 8 digits possible (two used)

Fourth number: 7 digits possible (three used)

For each of the 3 letters, we have the following possibilities:

First letter: 26 digits possible

Second letter: 25 digits possible (one used)

Third letter: 24 digits possible (two used)

The total number of license plates is the product of all these possibilities:

Number of plates = 10 * 9 * 8 * 7 * 26 * 25 * 24 = 78,624,000 license plates

The license plates can be formed if neither the digits nor the letters are repeated is 78,624,000.

A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

In a certain country, the car license plate is formed by 4 numbers from the digits 1-9 followed by 3 letters from the alphabet.

There are 10 numbers.

And there is 26 alphabet.

The license plates can be formed if neither the digits nor the letters are repeated will be

[tex](number)(alphabet)\\\\(9*8*7*6)(26*25*24) \\\\78,624,000[/tex]

The license plates can be formed if neither the digits nor the letters are repeated is 78,624,000.

Answer:

7,893,600

Step-by-step explanation:

Permutations

n = possible things used (26 letters)

r = how many at a time (5 at a time - this is without repeating)

nPr = n! / (n - r)!

26P5 = 26! / (26 - 5)!

26! = 26 x 25 x 24 x 23 x 22... = 403291461126605635584000000

(26 - 5)! = 21! = 51090942171709440000

An easy hack for solving division of large factorials is to use canceling.

26!/21! = 26 x 25 x 24 x 23 x 22 (because 21 down to 1 is cancelled by 21!)

= 7,893,600

Answer:

$150-$129-($129*7%)=$11.97

$531.25

$9414.5

Step-by-step explanation:

The amount that Anike would have left is the budgeted amount minus the regular price as well as the applicable sales tax.

Amount left=$150-$129-($129*7%)=$11.97

The amount that Harper would have to pay is the purchase price of $500 plus the 6.25% of sales price as sales tax i.e $500+$500*6.25%=$531.25

The yearly tax fees is the appraised value multiplied by property tax rate i.e $250,000*3.7658%=$9414.5

The property tax rate is 3.7658% not 37.658%

Using Pythagoras theorem,

H^2 = P^2 + B^2

h = 200

p = 2x

b = 6x

Solving,

(200)^2 = (2x)^2 + (6x)^2

40000 = 4x^2 + 36x^2

40000 = 40x^2

40000/40 = x^2

1000 = x^2

[tex]\sqrt{1000}[/tex] = x

Answer:

[tex]\theta=\dfrac{7}{4}\ \text{radian}[/tex]

Step-by-step explanation:

We have,

Radius of the circle is 12 cm

Arc length, l = 21 cm

It is required to find the central angle of the circle. The formula for the length of an arc of a circle is :

[tex]l=r\times \theta[/tex]

[tex]\theta[/tex] is central angle

[tex]\theta=\dfrac{l}{r}\\\\\theta=\dfrac{21}{12}\\\\\theta=\dfrac{7}{4}\ \text{radian}[/tex]

So, the angle at the centre of the circle is [tex]\dfrac{7}{4}\ \text{radian}[/tex].

Answer:

(0,−7)

Step-by-step explanation:

Since this is the equation of a straight line, there are no restrictions on what you could choose for a value of x. In "official" terms, we say the domain of the function is all real numbers.

Say you pick something simple like x=1. Now, insert this value, and the equation becomes

2−7=y

or y=−5

This means (1,−5) must be a point on the line, and it is also an ordered pair that satisfies the equation.

Answer:

36 miles

Step-by-step explanation:

Maya can bike 9 miles in one hours, meaning that she can bike 27 miles in 3 hours. Since Maya can run 18 miles in 3 hours, and half of 3 is 1.5, she can run 9 miles in 1.5 hours.

Biking Miles + Running Miles= Total Miles

27 + 9= 36 total miles

Step-by-step explanation:

(-2ab+4a-1) - (3ab+1)

-2ab+4a-1 -3ab-1 (you put them out of the brackets by following the procedures. )

-2ab-3ab+4a-1-1 (then you collect like terms)

-5ab+4a-2

Answer:

5 • (2x + 1) • (x + 1)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((2•5x2) +  15x) +  5

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  10x2 + 15x + 5  =   5 • (2x2 + 3x + 1)  

Trying to factor by splitting the middle term

3.2     Factoring  2x2 + 3x + 1  

The first term is,  2x2  its coefficient is  2 .

The middle term is,  +3x  its coefficient is  3 .

The last term, "the constant", is  +1  

Step-1 : Multiply the coefficient of the first term by the constant   2 • 1 = 2  

Step-2 : Find two factors of  2  whose sum equals the coefficient of the middle term, which is   3 .

     -2    +    -1    =    -3  

     -1    +    -2    =    -3  

     1    +    2    =    3    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  1  and  2  

                    2x2 + 1x + 2x + 1

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (2x+1)

             Add up the last 2 terms, pulling out common factors :

                    1 • (2x+1)

Step-5 : Add up the four terms of step 4 :

                   (x+1)  •  (2x+1)

            Which is the desired factorization

So the answer is:

 5 • (2x + 1) • (x + 1)

Answer:

Answer:

Minimum value = −13/4

Step-by-step explanation:

Answer:

-37/4

Step-by-step explanation:

The minimum value of the parabola y =x² + 5x – 3 is  f(-b/2a)

in this case a = 1 and b = 5 and c = -3

then

-b/2a = -5/2(1) = -5/2

then

f(-b/2a) =  f(-5/2) = -37/4

Answer:

C

Step-by-step explanation:

ax^2 + bx + c

x^2 + 12x + 3 = 7

x^2 + 12x = 4

Take b, half it, then square it--

x^2 + 12x + 36 = 40

That equation becomes

(x+6)^2 = 40

+ 6 = ± (square root of 40)

= 0.324555

Step-by-step explanation:

Answer:

x = -3 +/- sqrt(17)

Step-by-step explanation:

-6x - (x^2) - 8 = 0

-((x^2) + 6x + 8) = 0

(x^2) + 6x + 8 = 0

(x + 3)^2 - 1 = 0

(x + 3)^2 = 1

x + 3 = +/- sqrt(1)

x + 3 = +/- 1

x = -3 +/- 1

x = -4, -2

Answer: B. 140 cubic inches.

Step-by-step explanation:

The question is asking you to find the volume of the rectangular prism.

You can find this by using this formula:

[tex]V = w*h*l[/tex]

Where w is the width, h is the height, and l is the length.

Substitute the sides of the rectangular prism into the equation:

[tex]V = 3.5 * 10 * 4\\\\V = 140[/tex]

The volume of the prism is 140 cubic inches.

The correct answer is B.

Answer:

x = 4

Step-by-step explanation:

-3x + 4 = -8

-3x = -8 - 4

-3x = -12

x = -12/-3

x = 4

Answer: x = 4

Step-by-step explanation: Move all terms that don't contain x to the right side and solve.

-3x +4 = -8

     -4     -4

Subtract four from the four to cancel out and the -8.

That makes the equation -3x = -12

Then, divide by -3 by -3, then -12 divide by -3, to equal 4
