Answer:

Width=17m and Length=31m

Step-by-step explanation:

The perimeter of basketball court is rectangle in shape and is 96 m.

let us assume width be x m

so accordingly length will be 2*x-3=2x-3m

Perimeter= 2*(length+width)

96=2*(2x-3+x)

96=2*(3x-3)  

96=6x-6

6x=102

x=102/6

x= 17

so, the width is 17m

and length is 2x-3=2*17-3=31m

The area of the rectangular deck is 20 ft²

The length of a rectangular deck is five times its width.

Therefore,

l = 5w

perimeter of the rectangular deck = 2(l + w)

where

Therefore,

24 = 2(5w + w)

24 = 2 × 6w

12w = 24

divide both sides by 12

w = 24 / 12

w = 2

Therefore,

area of the rectangular deck = lw

area of the rectangular deck = 2 × 10

area of the rectangular deck = 20 ft²

Therefore, the area of the rectangular deck is 20 ft²

Answer:9514 1404 393

Answer:

 y = 95°

 x = 60°

Step-by-step explanation:

The applicable theorem is the one that says the exterior angle (120°) is the sum of the remote interior angles:

 120° = 25° +y

 95° = y . . . . . . . . . . subtract 25° from both sides

_____

If you like, you can get there by calculating x (or not):

 x = 180° -120°

 y = 180° -25° -x = 180° -25° -(180° -120°)

 y = 120° -25° . . . . . simplify — notice we didn't actually have to compute x

Putting SIN² A in evidence

SIN² A(1 + TG² A) = TG² A

SIN² A(SEC² A) = TG² A

SIN² A/COS² A = TG² A

TG² A = TG² A

Answer:

20,200

Step-by-step explanation:

Let the number of lines in each cube be a term in the sequence:

4, 12, 24, 40, ...

Work out the differences between the terms until the differences are the same:

[tex]4 \underset{+8}{\longrightarrow} 12 \underset{+12}{\longrightarrow} 24 \underset{+16}{\longrightarrow} 40[/tex]

     [tex]8 \underset{+4}{\longrightarrow} 12 \underset{+4}{\longrightarrow} 16[/tex]

As the second differences are the same, the sequence is quadratic and will contain an n² term.  The coefficient of n² is always half of the second difference.  Therefore, the coefficient of n² is 2.

To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare this sequence with the given sequence.

[tex]\begin{array}{|c|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4\\\cline{1-5}2n^2 & 2 & 8 & 18 & 32\\\cline{1-5}\sf operation & +2&+4&+6&+8 \\\cline{1-5}\sf sequence & 4 & 12 & 24 & 40\\\cline{1-5}\end{array}[/tex]

From inspection of the table, we can see that the "operation" is to add 2n to 2n².

Therefore, the nth term is:

[tex]a_n=2n^2+2n[/tex]

To find the number of lines in the 100th cube, substitute n = 100 into the equation for the nth term:

[tex]\begin{aligned}n=100 \implies a_{100} & = 2(100)^2+2(100)\\& = 2(10000)+200)\\& = 20000+200\\& = 20200\end{aligned}[/tex]

Therefore, the 100th cube has 20,200 lines.

The solution to the given system of equations is x = -2, y = 4, and z = -2. That is, the solution is (-2, 4, -2)

From the question, we are to solve the given system of equations

The given system of equations is

4x - y -2z = -8      ------------ (1)

-2x + 4z = -4        ------------ (2)

x + 2y = 6            ------------ (3)

From equation (2)

-2x + 4z = -4

4z = -4 + 2x

Divide through by 2

2z = -2 + x         ----------- (4)

From equation (3)

x + 2y = 6

2y = 6 - x

y = 3 - 1/2(x)      ---------- (5)

Substitute equations (4) and (5) into equation (1)

4x - y -2z = -8

4x -(3 -1/2(x)) - (-2 +x) = -8

4x -3 + 1/2(x) + 2 - x = -8

Multiply through by 2

8x - 6 + x + 4 -2x = -16

Collect like terms

8x + x -2x = -16 + 6 - 4

7x = -14

x = -14/7

x = -2

Substitute the value of x into equation (4)

2z = -2 + x

2z = -2 + (-2)

2z = -2 - 2

2z = -4

z = -4/2

z = -2

Substitute the value of x into equation (5)

y = 3 - 1/2(x)

y = 3 - 1/2(-2)

y = 3 + 1

y = 4

Hence, the solution to the given system of equations is x = -2, y = 4, and z = -2. That is, (-2, 4, -2)

By using a trigonometric relation, we can see that the missing angle is a = 41.1°

In the image we have a right triangle where we know the measures of the 3 sides and we want to find an interior angle.

These measures are:

Now we can use the trigonometric relation:

Cos(a) = (adjacent cathetus)/(hypotenuse)

Where a is the angle we want to get, so we can rewrite:

Cos(a) = 55/73

Now, if we apply the inverse cosine function in both sides, we get:

Acos(Cos(a)) = Acos( 55/73)

a = Acos(55/73) = 41.1°

By using a trigonometric relation, we can see that the missing angle on the right triangle is a = 41.1°

For the standard deviation, from the equation find the value of X₀ is 10.2

What is Standard Deviation ?

The standard deviation measures the degree of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean (also known as the expected value) of the set, whereas a high standard deviation indicates that the values are dispersed over a wider range.

Given

Z = 1.3

μ = 5 , σ = 0.4

Now for  X₀

Z =    X₀ -X / σ

1.3 =   X₀ - 5 / 0.4

X₀ = 10.2

Answer: Bikes were ordered as part of new order order is = 80 bikes

scooters were ordered as part of new order order is = 32 scooters.

Step-by-step explanation:

Given data,

A sporting goods store ordered new bikes and scooters.

For every 3 bikes ordered, 4 scooters were ordered.

Then, The ratio of the bike and scooter is equal to = 3:4

where,

bike ratio is 3

scooter ratio is 4

Then 48 bikes

original order = 64 scooter

                       = 64/4

                       = 16 scooters

However, bike is more popular than scooter.

So,

they changed it into new ratio = 5:2

where,

5 is equals to bikes ratio

and 2 is equal to scooter ratio.

Then,

5(original order) = 5(16)

                           = 80 bikes

2(original order) = 2(16)

                           = 32 scooters.

Therefore,

bikes were ordered as part of new order order is = 80 bikes

scooters were ordered as part of new order order is = 32 scooters.
