Answer:

Partially correct!!

Step-by-step explanation:

To find the area, you only need to multiply LENGTH x WIDTH. So, you did it correctly.

Not the height and the length. You wouldn't need the height to calculate area! Good try though! If you're still stuck next time you measure a door, look up how to calculate area if you are ever stuck.

Step-by-step explanation:

because im right

If a function is defined by the equation y = 2x−32, the equation that defines the inverse of this function would be: B. y=2x+32

To determine the inverse of the function, we would first replace x with y in the function:

y = 2x - 32

x = 2y - 32

x + 32 = 2y

Divide both sides by 2

x/2 + 32/2 = y

f−1(x) = x/2 + 32/2

The common facot between the denominatoes of the values is 2. So, when expanded, we have;

(x + 32)/2

So, the closest option that represents the inverse is B. y=2x+32.

Step-by-step explanation:

The number of teams and matches in the soccer league illustrates permutation and combination

There are 12 teams in the soccer league in the first season

The number of teams in the soccer league is given as n.

So, the total number of matches played in a season is:

Matches = n(n-1)/2

When the number of teams increases by 2, we have:

Matches = (n + 2)(n + 2 -1)/2

Also, the number of matches increases by 27.5%.

So, we have:

Matches = n(n-1)/2 * (1 + 27.5%)

Equate both equations

[tex]\frac{(n + 2)(n + 2 -1)}{2} = \frac{n(n-1)}{2} * (1 + 27.5\%)[/tex]

Simplify

[tex]\frac{(n + 2)(n + 1)}{2} = \frac{n(n-1)}{2} * (1.275)[/tex]

Multiply through by 2

[tex](n + 2)(n + 1) = n(n-1) * (1.275)[/tex]

Expand

[tex]n^2 + 3n + 2 = 1.275n^2 - 1.275[/tex]

Collect like terms

[tex]n^2 -1.275n^2+ 3n + 2 +1.275 = 0[/tex]

Evaluate the like terms

[tex]-0.275n^2+ 3n + 3.275 = 0[/tex]

Using a graphing calculator, we have:

n = -1 or n = 11.909

n cannot be negative.

So, we have:

n = 11.909

Approximate

n = 12

Hence, there are 12 teams in the soccer league in the first season

Step-by-step explanation:

Let X be the random variable that represents the weights of the fish.

Given: Weights of the fish in a certain lake are normally distributed with a mean of 10.1 lb ([tex]\mu[/tex]) and a standard deviation of 2.9 lb ([tex]\sigma[/tex]).

sample size : n= 32

The probability that the mean weight will be more than 10.9 lb:

[tex]P(\overline{X}>10.9)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{10.9-10.1}{\dfrac{2.9}{\sqrt{32}}})\\\\=P(Z>1.56)\\\\=1-P(Z<1.56)\\\\=1- 0.9406\ \ [\text{By p-value table}]\\\\=0.0594=5.94\%[/tex]

Hence, the required probability = 5.94%.

Answer:

Step-by-step explanation:

Given that the  function is  f(x)=1.6x+15,

we can see that the function corresponds to the equation of a straight line

that y=mx+c      

now comparing this function with the equation of a straight line

 f(x)=1.6x+15

  y=mx+c      

we can see that

x represents the number of golf balls in the package

15 is constant c which is the weight of the package used in the shipping

Answer:

$3.75

Step-by-step explanation:

Cost of one shirt = $12.25

cost of two shirt = 2*Cost of one shirt= 2*$12.25 = $25

cost of necklace = $8.50

cost of pair of shoes = $22.75

Total cost for the shopping = cost of two shirt+cost of necklace+ cost of pair of shoes

Total cost for the shopping = $25 + $8.50+ $22.75 = $56.25

Given that Maddy had done total shopping worth $56.25 but she gave cashier all her birthday money which is equal  to $60.

Then , cashier will return all the money from $60 exceeding $56.25

change returned to money = money given to cashier - total cost for shopping

change returned to Maddy = $60 - $56.25 = $3.75

Thus, Maddy got Back $3.75

Answer:

Piece1:  12.7 meters

Piece2:  39.9 meters

Product of the two to nearest tenth: 506.7

Step-by-step explanation:

Piece1:   x

Piece2:  x + 27.2

x + x + 27.2 = 52.6

2x + 27.2 = 52.6

2x = 25.4

x = 12.7

Piece1:   12.7

Piece2:  12.7 + 27.2 = 39.9

Product of the two pieces:

12.7 * 39.9 = 506.73

Answer: 18693.51075= £18,693.51

Step-by-step explanation:

16470.45/100=164.7045

164.7045x13.5=2223.51075

2223.51075=16470.45=18693.51075

18693.51075= £18,693.51

The increment of £16470.45 by 13.5% is £18693.96.

A part per hundred is what the percentage denotes. The symbol '%' is used to symbolise it. Example percentages include: 10% is represented as the fraction 1/10.

The amount is given as  £16470.45.

As, the amount is increased by 13.5%.

Thus 13.5% of £16470.45 will be calculated as,

= 16470.45 ×(13.5/100)

= 2223.51

Thus, the 13.5% of the amount will be £2223.51

As, the incremented amount is calculated as  £2223.51.

The amount after the increment will be,

= 16470.45 + 2223.51

= 18693.96

Therefore, the total amount after the increment of 13.5% is £18693.96.

Answer:

y = x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, - 3 ) and (x₂, y₂ ) = (7, 8 )

m = [tex]\frac{8-(-3)}{7-(-4)}[/tex] = [tex]\frac{8+3}{7+4}[/tex] = [tex]\frac{11}{11}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (7, 8 ) , then

8 = 7 + c ⇒ c = 8 - 7 = 1

y = x + 1 ← equation of line

You need to subtract 11 from x, (which is the first number in the parenthesis) because the rule is (x-11, y+4) and add 4 to y.

I really hope this helps!

The value represents the is D(-5,5), E(-3,4), F(-6,0), G(-8,1) (-8,1) . A rectangle is a quadrilateral with four right angles in the Euclidean plane.

A rectangle is a quadrilateral with four right angles in the Euclidean plane. A parallelogram with a right angle or an equiangular quadrilateral, where equiangular means that all of its angles are equal, are other ways to describe it. A rectangle with four equally length sides is a square.

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.

Given,

vertices D(61), E(8,0),

F(5.-6), and G(3-5); (x, y)(x-11, y + 4)

Because the rule is (x-11, y+4), you must subtract 11 from x, which is the first number in the parenthesis, and then add 4 to y.

D(-5,5), E(-3,4), F(-6,0), G(-8,1) (-8,1)

Therefore D(-5,5), E(-3,4), F(-6,0), G(-8,1) (-8,1)  is the value represents the rectangle.
