It takes 42,000 lbs of sand to fill 10 park sandboxes. How much sand will the parks and recreation department need to put in each of the 10 sandboxes?

Answer:

D) 55°.

Step-by-step explanation:

The sum of angles in a triangle add up to 180°.

[tex]y+(y+30)+40=180[/tex]

[tex]2y+70=180\\[/tex]

Subtract 70 from both sides:

[tex]2y+70-70=180-70[/tex]

[tex]2y=110[/tex]

Divide both sides by 2:

[tex]\frac{2y}{2}=\frac{110}{2}[/tex]

[tex]y=55[/tex]

Answer:

N=10

Step-by-step explanation:

-2n=-n+8

subtract 8 on both sides

-10/-n= -n/-n

the variables cancel out and you divide -10 with -1 because your variable is always 1 giving you the answer

n=10

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{n = 5}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{n - 2 = - n + 8}[/tex]

Move n to left hand side and change it's sign

Similarly, move 2 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{n + n = 8 + 2}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{2n = 8 + 2}}[/tex]

Add the numbers: 8 and 2

[tex] \longrightarrow{ \sf{2n = 10}}[/tex]

Divide both sides by 2

[tex] \longrightarrow{ \sf{ \frac{2n}{2} = \frac{10}{2}}} [/tex]

Calculate

[tex] \longrightarrow{ \sf{n = 5}}[/tex]

Hope I helped!

Best regards! :D

The two numbers are [tex]-2[/tex] and [tex]-14[/tex].

It is given that,

Explanation:

Let [tex]x[/tex] be the one number. Then the second number is [tex]7x[/tex].

Sum of two numbers is negative sixteen.

[tex]x+7x=-16[/tex]

[tex]8x=-16[/tex]

[tex]x=\dfrac{-16}{8}[/tex]

[tex]x=-2[/tex]

The value of other number is:

Answer:

[tex]x = \frac{17}{18}[/tex]

[tex]y = \frac{23}{6}[/tex]

Step-by-step explanation:

Given

[tex]y = 3x + 1[/tex]

[tex]Points = (0,0)\ to\ (-3,4)[/tex]

Required

Determine (x,y) equidistant from the equation and the given point

This question will be answered using distance formula;

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Considering The first Point [tex](0,0)\ to\ (x,y)[/tex]

[tex](x_1 ,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (x,y)[/tex]

The distance is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]d = \sqrt{0 - x)^2 + (0 - y)^2}[/tex]

[tex]d = \sqrt{(- x)^2 + (- y)^2}[/tex]

[tex]d = \sqrt{x^2 + y^2}[/tex]

Considering the second point: [tex](x,y)\ to\ (-3,4)[/tex]

[tex](x_1,y_1) = (x,y)[/tex]

[tex](x_2,y_2) = (-3,4)[/tex]

The distance is:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]d = \sqrt{(x - (-3))^2 + (y - 4)^2}[/tex]

[tex]d = \sqrt{(x + 3)^2 + (y- 4)^2}[/tex]

[tex]d = \sqrt{x^2 + 6x + 9 + y^2- 8y + 16}[/tex]

[tex]d = \sqrt{x^2 + 6x + y^2- 8y + 16 + 9}[/tex]

[tex]d = \sqrt{x^2 + 6x + y^2- 8y + 25}[/tex]

Equate both values of d

[tex]\sqrt{x^2 + 6x + y^2- 8y + 25} = \sqrt{x^2 + y^2}[/tex]

Square both sides

[tex]x^2 + 6x + y^2- 8y + 25 = x^2 + y^2[/tex]

Collect Like Terms

[tex]6x - 8y + 25 = x^2 -x^2+ y^2 -y^2[/tex]

[tex]6x - 8y + 25 =0[/tex]

Recall that [tex]y = 3x + 1[/tex]

[tex]6x - 8(3x + 1) + 25 = 0[/tex]

[tex]6x - 24x - 8 + 25 = 0[/tex]

[tex]-18x+ 17 = 0[/tex]

[tex]-18x=- 17[/tex]

Solve for x

[tex]x = \frac{-17}{-18}[/tex]

[tex]x = \frac{17}{18}[/tex]

Substitute [tex]\frac{17}{18}[/tex] for x in [tex]y = 3x + 1[/tex]

[tex]y = 3 * \frac{17}{18} + 1[/tex]

[tex]y = \frac{17}{6} + 1[/tex]

[tex]y = \frac{17 + 6}{6}[/tex]

[tex]y = \frac{23}{6}[/tex]

Answer:

360 ft

Step-by-step explanation:

Answer:

If the bisector of AB is at origin (0,0) and A is at (4,0)

we can say that the mid-point of the line AB is at (0,0)

Hence, the point B will be 4 units on the other side of the origin

Therefore, the co-ordinates of B are: (-4,0)

Since the line AB is 4 units to the left and 4 units to the right of the origin,

the length of line-segment AB is 4 + 4 = 8 units

Answer:

Step-by-step explanation:

In this exercise, we want to convert the sellers gain or say represent the sellers gain as a percentage

given data

given that he sells a total of 75 apples

and also that he gains 15 apples

To solve or show the percentage gain, we have to divide the total sales by the profit made and multiply the result by 100, that way we have the percentage gain.

i.e (profit/total sales)*100

= (15/75)*100

= 0.2*100

= 20%

Answer: yes, it is valid

Step-by-step explanation:

Given the following probability distribution :

X ________f(x)

100,000___ .10

200,000__ .20

300,000 __ .25

400,000 __ .30

500,000 ___.10

600,000 ___.05

To examine the validity of the distribution :

Each individual observation or point must have probability value in within the range (0 < p ≤ 1)

Where p = probability value.

The sum of the individual probabilities must add up to 0

(0.1 + 0.2 + 0.25 + 0.3 + 0.1 + 0.05)

= 1

Since the two consitions are meet, then, the probability distribution is valid

Substitute the coordinates of M and D into the formula:

[tex]( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&= \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4 &\\ - 2= x1 + 1&, &10 &= y1 + 4 &\\ x1= - 2 - 1&,& y1 &= 10 - 4 &\\ x1= - 3&, &y1& =6 \: \: \: \: \: \: \: \: \: \: &[/tex]

Thus, the coordinates of G is (-3,6).

Answer:

D'(-2, -1)

E'(5, 5)

Step-by-step explanation:

DE has the coordinates of the endpoints as D(-3, -4) and E(4, 2).

These points are translated by the rule to give the translated image as D'E',

(x, y) → (x + 1, y + 3)

By following this rule,

D(-3, -4) → D'(-3 + 1, -4 + 3)

             → D'(-2, -1)

E(4, 2) → E'(4 + 1, 2 + 3)

          → E'(5, 5)

Now we can graph these image points having coordinates D'(-2, -1) and E'(5, 5).

Answer:

The probability of getting defective product from warehouse C is 0.3448

Step-by-step explanation:

Missing question "Assume that Ware houses A, B and C ship 30%, 20% and 50% of the dot-com's sales respectively.

P(A) = Probability of product that comes from warehouse A

P(B) = Probability of product that comes from warehouse B

P(C) = Probability of product that comes from warehouse C

P(A) =  30% = 0.30, P(B) =  20% = 0.20, P(C) =  50% = 0.50

Let D denotes the number of defective products

P(D|A) = 3% = 0.03

P(D|B) = 5% = 0.05

P(D|C) = 2% = 0.02

The probability of getting defective product from warehouse C is as below using the Bayes Rule

P(C|D) = P(D|C) P(C) / P(D|A)P(A) + P(D|B)P(B) + P(D|C)P(C)

P(C|D) = 0.02 * 0.50 / (0.03*0.30) + (0.05*0.20) + (0.02*0.50)

P(C|D) = 0.01 / 0.009 + 0.01 + 0.01

P(C|D) = 0.01 / 0.029

P(C|D) = 0.3448

Therefore the probability of getting defective product from warehouse C is  0.3448.
