3 out of every 5 picks are orange. If 12 picks are orange, how many picks are there in all?

Answers

Answer 1
So basically the formula is:
3/5 = 12/n
so then we get 3n = 60
n = 20
so there are 20 picks in all

12 ticket sellers, 25 cleaning persons, and 15 ushers employees will be paid $10, $7.50, 8.50 per hour for 50 hours per month what is the monthly salary

Answers

----------------------------------------------------------
Ticket Sellers
----------------------------------------------------------
1 ticket seller  = $10 x 50
1 ticket seller  = $500

12 ticket sellers = $500 x 12
12 ticket sellers = $6000

----------------------------------------------------------
Cleaning person
----------------------------------------------------------
1 cleaning person = $7.50 x 50 
1 cleaning person = $ 375

25 cleaning person = $375 x 25
25 cleaning person = $9375

----------------------------------------------------------
Ushers
----------------------------------------------------------
1 usher = $8.50 x 50
1 usher = $425

15 ushers = $425 x 15
15 ushers = $6375

----------------------------------------------------------

The mean of 10,12,16,20,p,26 is 17.Find the value of p.

Answers

there are 6 numbers total

17 * 6 = 102

10 + 12 + 16 + 20 + 26 = 84

p = 102-84 = 18

p = 18
Answer:  " p = 18 " .
__________________________________________________
Explanation:
__________________________________________________
The [arithmetic] mean =
 
{the sum of all the values in the data set} 
        divided by {the number of values in the number set} ; 
__________________________________________________
  → 17 = (10 + 12 + 16 + 20 + 26 + p) / 6 ;  

__________________________________________________
→ (10 + 12 + 16 + 20 + 26 + p)  = 17 * 6 ;

 →     (p + 84) = 102

Subtract "84" from each side of the equation; 
  to isolate "p" on one side of the equation; & to solve for "p" ; 

→ p + 84 – 84 = 102 – 84 ; 

→ p = 18 . 
_________________________________________________

The answer is:  " p = 18 " .

El lote de la familia lópez tiene un lote de 16m*10m y se desea construir una casa de base rectangular en el centro de el.¿que dimensiones debe tener el rectángulo del piso de la casa si tiene un área de 91m2?

Answers

The dimensions of the house should be 7 m by 13 m.

If the house is to be centered, we will take the same amount from the width as we do from the length of the lot for the dimensions.  This gives us (10-x) and (16-x) as the dimensions.

The area of a rectangle is found by multiplying the length and width:
(10-x)(16-x) = 91

Multiplying the binomials we have:
10*16 - x*10 - x*16 -x*(-x) = 91
160 - 10x - 16x --x² = 91
160-10x-16x+x² =91

Combine like terms:
160-26x+x²=91

Rewrite this in standard form:
x²-26x+160=91

Subtract 91 from both sides:
x²-26x+160-91 = 91-91
x²-26x+69 = 0

Factoring this, we look for factors of 69 that sum to -26.  -23*-3 = 69 and -23+-3 = -26, so:

(x-23)(x-3) = 0

Using the zero product property we know that either x-23=0 or x-3=0, so x=23 or x=3. 

x was the amount we take off of the width and length of the lot; if we took 23m off of it, 10-23 gives us a negative amount, which is not realistic. This means both the width and length are subtracted by 3.

10-3 = 7 and 16-3 = 13.

These are the dimensions of the house.

The first step you would take is to combine all like terms in the parentheses.

Answers

7(2) + 30 = 14+30 = 44
3(2^2) -5(2)+20 = 12 - 10 + 20 = 22
4(2^2) +8(2) = 16 + 16 = 32

P = 31 + 44 + 22 + 32 = 129

answer
129 inches

Answer:

Perimeter is 129 inches.

Step-by-step explanation:

We are given,

A quadrilateral with sides lengths [tex](4x^2+8x),(3x^2-5x+20),(7x+30),31[/tex] inches.

Now, the values of the side lengths when x = 2 are,

[tex](4x^2+8x)=(4\times 2^2+8\times 2)=(4\times 4+16)=16+16=32\ inch\\\\(3x^2-5x+20)=(3\times 2^2-5\times 2+20)=(3\times 4-10+20)=12+10=22\ inch\\\\(7x+30)=(7\times 2+30)=14+30=44\ inch[/tex]

Since, Perimeter of a quadrilateral = Sum of its sides.

Then, Perimeter of given quadrilateral = 32 + 22 + 44 + 31 = 129 inches.

Hence, the perimeter is 129 inches.

which are the solutions of the quadratic equation x^2=9x+6

Answers

You can use the quadratic equation to solve this once you have this set equal to zero. The answers would be roughly 9.6 and -0.6. 

The solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex]are:

[tex]\[x = \frac{9 + \sqrt{105}}{2}\][/tex] and [tex]\[x = \frac{9 - \sqrt{105}}{2}\][/tex]

To find the solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex], we need to rewrite it in standard quadratic form [tex]\(ax^2 + bx + c = 0\).[/tex]

Given:

[tex]\[x^2 = 9x + 6\][/tex]

Subtract [tex]\(9x\) and \(6\)[/tex] from both sides to get it in standard form:

[tex]\[x^2 - 9x - 6 = 0\][/tex]

Now, to solve this quadratic equation, we can factor it or use the quadratic formula:

The quadratic formula is:

[tex]\[x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}\][/tex]

For our equation:

[tex]\[a = 1, b = -9, \text{ and } c = -6\][/tex]

Substituting these values into the quadratic formula:

[tex]\[x = \frac{-(-9) \pm \sqrt{(-9)^2-4(1)(-6)}}{2(1)}\]\[x = \frac{9 \pm \sqrt{81+24}}{2}\]\[x = \frac{9 \pm \sqrt{105}}{2}\][/tex]

So, the solutions of the quadratic equation [tex]\(x^2 = 9x + 6\)[/tex]are:

[tex]\[x = \frac{9 + \sqrt{105}}{2}\][/tex] and [tex]\[x = \frac{9 - \sqrt{105}}{2}\][/tex]

Answers

Area = (1/2) x 2.75 x 1.32 x sin(35 deg) = 1.815 x (0.573576) = 1.04 sq. miles.

Answer:

2.08 mi²

Step-by-step explanation:

Since, the area of the triangle is,

[tex]A=s_1\times s_2\times sin \theta[/tex]

Where, [tex]s_1[/tex] and [tex]s_2[/tex] are adjacent sides and [tex]\theta[/tex] is the included angle of these sides,

Here, [tex]s_1[/tex] = 2.75 miles,

[tex]s_2[/tex] = 1.32 miles,

And, [tex]\theta[/tex]  = 35°,

hence, the area of the given triangle is,

[tex]A=2.75\times 1.32\times sin 35^{\circ}[/tex]

[tex]= 3.63\times 0.57357643635[/tex]

Maria plans to fill pots in her garden with soil and plant food. Maria has 8 1/2 quarts of soil as 1 1/2 quarts of plant food. Each pot requires 3/4 quart of soil. For how many pots does Maria have enough soil?

Answers

1. You have the following information:

 - Maria has 8 1/2 quarts of soil.
 - Each pot requires 3/4 quart of soil.

 2. Keeping this on mind, you can convert the mixed number 8 1/2 and the fracion 3/4 to decimals, as below: 

 8 1/2=8.5 quarts
 3/4=0.75 quarts

 3. Therefore, you have:

 1 pot-----0.75 quarts
       x-----8.5 quarts

 x=(8.5x1)/0.75
 x=11 pots

 For how many pots does Maria have enough soil?

 The answer is: 11 pots

Answer: choice A) -4

Step 1) Draw a vertical line through 1 on the x axis

Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)

Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis. 

So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.

In short, this is why f(1) = -4
