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

x = 31.62 ft

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: 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:

10

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:

$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%

Answer: I think its 24.5 dollars left

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:

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

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

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:

Answer:

-5ab+4a-2

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:

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:

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:

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)

$165 worth of hamburgers + $180 worth of hot dogs = $345 total sales revenue

Hello hello!

Solving this is simple, just remember the vertical angles theorem. Due to this theorem, you are able to conclude that x+40 and 60 are equal in terms of their angle measure. This means that to solve this, we need to set both sides equal to each other and solve for x, and plug it in!

STEP ONE: 60 = x + 40

DO: Subtract 40 from both sides.

STEP TWO: 20 = x

DO: You've answered the question!
