1/6y+1/6(y+12)-2
1/3y+1/3(6-y)

Answers

Answer:

The answer is 1/6y+1/6(y+12)-2

Answer:

1/6y+1/6(y+12)- 2

Step-by-step explanation:

Distribute [tex]\frac{1}{6}[/tex] through the parentheses : [tex]\frac{1}{6}[/tex]y + [tex]\frac{1}{6}[/tex]y + 2 - 2Remove the opposites and calculate ( since two opposites add up to zero remove them from the expression) : [tex]\frac{1}{6}[/tex]y + [tex]\frac{1}{6}[/tex]yCalculate the sum : [tex]\frac{1}{3}[/tex] y

Georgia said she could make 11 out of 20 blankets for a craft show. She has already made 3 blankets. What percent of the 20 blankets does she still have to make? helppppppppppppppppppppp pleaseeeeeeeeeeeeeeeeeeeeeeeeeee i wil give you 100 0point i swerare

Answers

Answer:

Step-by-step explanation:

Total she can make = 11

Amount she has already made = 3

Amount she still have to make = 11-3 = 8

% of the 20blanket she still have to make = 8/20×100

= 8×5

= 40%

Hence she Still need to make 40% of the 20blanket

Answer:

11-3=8

40% of 20 is 40/100*20 = 8

Answer:

4N left

5N left

0N (balanced)

9N right

Step-by-step explanation:

The net force is the vector sum of all of the forces acting on an object. To find the net force when there are two opposite forces subtract the smaller number from the larger, for example, 7-2. Then take to total, 5N, and add the direction of the stronger force. If the equation equals zero that means you have a balanced force. To find the force of two actions in the same direction simply add them.

A 2 1/2 pound of grass seed covers 1/8 of an acre. How much grass seed is needed for 1 acre

The weekly amount spent by a small company for in-state travel has approximately a normal distribution with mean $1450 and standard deviation $220. What is the probability that the actual expenses will exceed $1560 in 20 or more weeks during the next year?

Answers

Answer:

0.0903

Step-by-step explanation:

Given that :

The mean = 1450

The standard deviation = 220

sample mean = 1560

[tex]P(X > 1560) = P( Z > \dfrac{x - \mu}{\sigma})[/tex]

[tex]P(X > 1560) = P(Z > \dfrac{1560 - 1450}{220})[/tex]

[tex]P(X > 1560) = P(Z > \dfrac{110}{220})[/tex]

P(X> 1560) = P(Z > 0.5)

P(X> 1560) = 1 - P(Z < 0.5)

From the z tables;

P(X> 1560) = 1 - 0.6915

P(X> 1560) = 0.3085

Let consider the given number of weeks = 52

Mean [tex]\mu_x[/tex] = np = 52 × 0.3085 = 16.042

The standard deviation = [tex]\sqrt {n \time p (1-p)}[/tex]

The standard deviation = [tex]\sqrt {52 \times 0.3085 (1-0.3085)}[/tex]

The standard deviation = 3.3306

Let Y be a random variable that proceeds in a binomial distribution, which denotes the number of weeks in a year that exceeds $1560.

Then;

Pr ( Y > 20) = P( z > 20)

[tex]Pr ( Y > 20) = P(Z > \dfrac{20.5 - 16.042}{3.3306})[/tex]

[tex]Pr ( Y > 20) = P(Z >1 .338)[/tex]

From z tables

P(Y > 20) [tex]\simeq[/tex] 0.0903

A school is installing a flagpole in the central plaza. The plaza is a square with side length 100 yards as shown in the figure below. The flagpole will take up a square plot in the middle of the plaza and its base will have an area of x^2−6x+9 yd^2.

Area of the flagpole plot: x^2−6x+9

Find the length of the base of the flagpole by factoring. (Hint: Because the area of the flagpole is an expression that involves the variable x, the length of the base will also involve the variable x.)

The length of the base of the flagpole is

Answers

Answer:

[tex]x-3[/tex]

Step-by-step explanation:

The area of the flagpole base is [tex]x^2-6x+9\ \text{yd}[/tex]

where the factor of the equation is the length of the base.

In order to find the length we need to factorize the equation

[tex]x^2-6x+9[/tex]

[tex]=x^2-3x-3x+9[/tex]

[tex]=x(x-3)-3(x-3)[/tex]

[tex]=(x-3)(x-3)[/tex]

The length of the base of the flagpole is [tex](x-3)\ \text{yd}[/tex].

The area of a square base is the product of the side lengths.

The length of the base is x - 3

The area is given as:

[tex]\mathbf{Area =x^2 - 6x + 9}[/tex]

Expand

[tex]\mathbf{Area =x^2 - 3x - 3x + 9}[/tex]

Factorize

[tex]\mathbf{Area =x( x- 3) - 3(x - 3)}[/tex]

Factor out x - 3

[tex]\mathbf{Area =( x- 3) (x - 3)}[/tex]

Express as squares

[tex]\mathbf{Area =( x- 3)^2}[/tex]

Rewrite the area as:

[tex]\mathbf{Length^2 =( x- 3)^2}[/tex]

Take square roots of both sides

[tex]\mathbf{Length =x- 3}[/tex]

Hence, the length of the base is x - 3
