Answer:

a) Length [tex]x + 12[/tex], Width [tex]x - 3[/tex], b) [tex]x = 3[/tex]

Step-by-step explanation:

a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:

[tex]A = x^{2} + 9\cdot x - 36[/tex]

[tex]A = (x+12)\cdot (x-3)[/tex]

Length

[tex]x + 12[/tex]

Width

[tex]x - 3[/tex]

b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:

- When both binomials are negative.

[tex]x \leq 3[/tex] and [tex]x \leq -12[/tex]

[tex]x \leq -12[/tex]

- When both binomials are positive.

[tex]x \geq 3[/tex] and [tex]x \geq -12[/tex]

[tex]x \geq 3[/tex]

Since x is an integer, x must be positive and therefore the least possible value of x is:

[tex]x = 3[/tex]

135 new employees should be hired by company to increase 30% of the employees.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The number of employees in electronic company is 450.

The company plans to increase its staff by 30%

We need to find the number of employees to be hired by company.

30% of 450

Thirty percentage of four hundred fifty.

Convert 30% to decimal value by dividing with 100.

30/100=0.3

Now multiply 0.3 with 450

0.3×450

One hundred thirty five.

Answer:

The length of the fence is 38 yards

These are the expressions

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

The length of the fence is the perimeter of the garden which is the expression that Chole could use

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Answer:

y = sin(x+90)

Step-by-step explanation:

The shape of the graph shown is a y = cos x graph

Since that is not an option, we know that it must be translated somewhat

Sin x and cos x graphs are the exact same in shape, but differ by 90°

Y = sin (x+90) is the same as a Y = cos x graph, so Y = sin(x+90) is our answer

Answer:

Assuming that the die has sides that are equal and that the sides are numbered 1 to 666 (since there are 666 sides), then the probability of rolling a 555 and flip a heads is 1/1,332.

Step-by-step explanation:

Probability of flipping a heads: 1/2

Probability of rolling a 555: 1/666

Multiply the two probabilities to get your probability for rolling both.

Answer:

  1229 km

Step-by-step explanation:

The missing angle is ...

  180° -60° -75° = 45°

Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.

  ?/sin(75°) = 900 km/sin(45°)

  ? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km

The UFO is about 1229 km from KA-12.

Answer: e = 10

Step-by-step explanation: 9e + 4 = -5e + 14 + 13 e

Now lets bring the variables and numbers on a different side

Remember that when the numbers go to the other side the sign changes

so 4 - 14 = -9e + 13e -5e

-10 = -e

10 = e

if plug in both equations on a graph then you will see that when e = 10 the lines meet at 94.

Answer:

[tex]e=10[/tex]

Step-by-step explanation:

[tex]9e+4=-5e+14+13e[/tex]

Simplify both sides by combining [tex]-5e+13e[/tex] :

[tex]9e+4=8e+14[/tex]

Isolate the variable e. Subtract  8e from both sides:

[tex]9e-8e+4=8e-8e+14\\\\e+4=14[/tex]

Subtract 4 from both sides:

[tex]e+4-4=14-4\\\\e=10[/tex]

Answer:

Step-by-step explanation:

Given that, a series of triangle,

For the sine and cosine to be equal, then,

Sinθ = Cosθ

From, trigonometry identities

Sinθ = Cos(90-θ)

Then,

θ = 90-θ

θ + θ = 90

2θ = 90

θ = 90 / 2

θ = 45°

From the triangle given, using trigonometry ratio,

Sinθ = opposite / hypotenuse.

Sinθ = 20 / 25

Sinθ = 0.8

θ = arcsin(0.8)

θ = 53.13°

The other angles at the triangle is

90-53.13 = 36.87°.

The volume of the sphere is 500/3 π cubic units. What is the value of x?  

x = radius

Answer:

x = 5 units

Step-by-step explanation:

The volume for a sphere can be represented as follows

volume = 4/3πr³

volume = 500/3 π

x = radius

volume = 4/3πx³

500/3 π = 4/3 × π × x³

multiply both sides by 3/4

500/3 × π × 3/4 = π × x³

125π = πx³

divide both sides by π

x³ = 125π/π

x³ = 125

cube root both sides

x³ = ∛125

x = 5 units

Answer:

I think the answer is 4 1/2 out of 30 chance.

Step-by-step explanation:

The probability of selecting two solid chocolates in a row is 4/145.

To calculate the probability of selecting two solid chocolates in a row, we need to consider the probability of selecting a solid chocolate on the first draw and the probability of selecting a solid chocolate on the second draw, given that a solid chocolate was selected on the first draw.

There are a total of 30 chocolates, with 9 solid chocolates. Therefore, the probability of selecting a solid chocolate on the first draw is 9/30.

After eating the first chocolate, there are now 29 chocolates left in the box, with 8 solid chocolates remaining. So the probability of selecting a second solid chocolate is 8/29.

Since the two events are independent, we can multiply the probabilities of each event to find the probability of both events occurring:

Probability of selecting two solid chocolates = (9/30) * (8/29) = 4/145.

[tex]\large \boxed{\text{1. B. $T_{{<6, -2>}}(QRST)$; 2. D. A$'$ (3,9), B$'$(4,0), C$'$(5,5)}}[/tex]

Step-by-step explanation:

1. Translation of Quadrilateral

A translation rule tells you how much to add to the values of x and y.

In your translation, the value of x increases from -5 to +1 — a distance of 6 units.

The value of y decreases from +4 to +2 — a distance of 2 units.

[tex]\text{The translation rule is $\large \boxed{\mathbf{T_\mathbf{{<6, -2>}}(QRST)}}$}[/tex]

2. Translation of triangle

The rule tells you to translate the triangle two units to the left and three units up, as in the second figure below.

A(5,6)  ⟶ A'(3,9)

B(6,-3) ⟶ B'(4,0)

C(7,2)  ⟶ C'(5,5)

The coordinates of the vertices of ∆A'B'C' are A'(3,9), B'(4,0), C'(5,5).

They're same side interior angles because since it's a parallelogram, the lines are parallel, and in this case, AB and CD are the parallel lines, AD is the transversal, and therefore, x and 115 are same side interior.

Same side interior angles are supplementary so x + 115 = 180

x = 180 - 115 = 65

x^2 = 36

x = 6 (-6 can't be a length)

Answer:

The Answer Is 6

Step-by-step explanation:

By Pythagoras Theorem

(AC)^2 = (AB)^2 + (BC)^2

(AB)^2 = (AC)^2 - (BC)^2

Answer:

111 pounds

Step-by-step explanation:

A boy holding a stack of 9 identical books steps on a scale and weighs 138 pounds.

If the boy's weight is represented as B and the books are represented as b, this implies that:

B + 9b = 138

The boy then holding a stack of 3 of the same books again steps on the scale and weighs 120 pounds. This implies that:

B + 3b = 120

This has yielded two simultaneous equations:

B + 9b = 138

B + 3b = 120

We can solve by subtracting the second from the first.

B + 9b = 138

- (B + 3b = 120)

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

=> 6b = 18

b = 18 / 6 = 3 pounds

This means that each book weighs 3 pounds.

Putting b back in the second equation:

B + (3 * 3) = 120

B + 9 = 120

B = 120 - 9

B = 111 pounds

Therefore, the boy weighs 111 pounds.

Answer:

The boy would weigh 111 lbs.

Answer:

31.2

Step-by-step explanation:

To work out 60% of 52 you would first need to find 10%. You can do this by dividing 52 by 10, this gives you 5.2.

The final step is to multiply 5.2 by 6, this gives 31.2. This is because in order work out 60% you multiply 10% by 6.

1) Divide 52 by 10.

[tex]52/10=5.2[/tex]

2) Multiply 5.2 by 6.
