Answer:

Answer= 7

Step-by-step explanation:

the unknown number being, x, .

i think of a number ( x), double it, ( 2× x)= 2x, and add 11 to be ( 2x + 11), i get 25.

So, the equation will be:

2x + 11 = 25.

to solve it, take (+11) to the equals side and it will change to (-11), or in other words, subtract 11 on both sides.

the equation will thus remain to be:

2x = 25-11

2x = 14.................Divide both sides by 2 to remain with x

so, X = 7.

Step-by-step explanation:

Label the triangle (Best for organization)

Longest side of the triangle is called the Hypotenuse, or Hyp.

Shortest side of the triangle is called the Opposite, or Opp.

Last side of the triangle is called the Adjacent, or Adj.

Formula

[tex]sin[/tex] x*=[tex]\frac{Opp}{Hyp}[/tex]

Find the inverse (value for "?")

sin x*=17/30

x*=[tex]sin^{-1}[/tex][tex](\frac{17}{30} )[/tex]

34.5*-->35*

?=35*

Triangle interior angles amount in 180 degrees

180-(35+33)=112*

Exterior angle equals the two opposite interior angles (aka/ defined as the Exterior Angle Theorem)

R=33*+112*

R=145*

When there is a recession, the employees will have to с learn new skills or face unemployment.

Recessions are a period of low business productivity which means that jobs would become very competitive.

An employee should therefore learn new skills that will make them more attractive in the market or they will probably end up unemployed.

Step-by-step explanation:

for the (a) put 6 in for x in h(x)=x/3

which looks like this...

h(6)=6/3 so, h=2

not put 2 in for x in g(x)=√3

which would end up as...

g(x)=√3 since there is no x in the equation

now finally put √3 in for x in f(x)=x^3

so, f(√3)= √3^3

which is... f(x)= 3√3

[Answer] a= 3√3

Answer:

[tex]\displaystyle [6, -3][/tex]

Step-by-step explanation:

To begin this process, we will first select the second equation. Here is how the Substitution method wourks:

[tex]\displaystyle \left \{ {{3x + 5y = 3} \atop {x + 2y = 0}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {x = -2y}} \right. \\ \\ 3[-2y] + 5y = 3 \hookrightarrow -6y + 5y = 3 \hookrightarrow -y = 3; -3 = y, 6 = x \\ \\ \\ \boxed{[6, -3]}[/tex]

So, you substitute [tex]\displaystyle x[/tex]for [tex]\displaystyle -2y[/tex]and continue combining like-terms until you receive the y-value. You then plug this back into the system to get the x-value, which was what you saw.

Answer:

∠a= 65°, ∠b= 115°, ∠c= 25°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. This is abbreviated to '∠ sum of ∆'.

∠c +55° +60° +40°= 180° (∠ sum of ∆PQR)

∠c +155°= 180°

∠c= 180° -155°

∠c= 25°

∠a +60° +55°= 180° (∠ sum of ∆PQS)

∠a +115°= 180°

∠a= 180° -115°

∠a= 65°

The sum of the angles on a straight line is 180°. It's abbreviation is 'adj. ∠s on a str. line'.

∠b +∠a= 180° (adj. ∠s on a str. line)

∠b +65°= 180°

∠b= 180° -65°

∠b= 115°

An easy way to figure out the answer fast is to plug the x values into the equation.

Wavelength is the ratio of speed and frequency. The wavelength of yellow light is 5.8 × 10⁻⁷ m. Then the correct option is A.

The division means the separation of something into different parts, sharing of something among different people, places, etc.

Yellow light has a frequency of 5.2 × 1014 Hz and travels at a speed of 3.0 × 108 m/s. Then the wavelength is given as

[tex]\lambda = \dfrac{v}{f}\\\\\\\lambda = \dfrac{3.0 \times 10^8}{5.2 \times 10^{14}}\\\\\\\lambda = 5.76\times 10 ^{-7} \approx 5.8 \times 10 ^{-7}[/tex]

Step-by-step explanation:

Area of a rectangle

The area of a rectangle of dimensions x, y is:

A=x.y

The diagram provided in the question is to a scale of 1 inch=16 ft.

We have provided a modified diagram where all the dimensions are also shown in ft.

The longer side of the shape is 4*16=64 ft

The smaller side of the shape is 3*16=48 ft

The bottom side of the store is 2 1/4*16=36 ft

The leftmost side of the store is 1 3/4*16=28 ft

We need to find the value of x and y.

The value of x is x=64 ft - 36 ft = 28 ft

The value of y is y=48 ft - 28 ft = 20 ft

The area of the whole rectangle of dimensions 48 ft and 64 ft is:

[tex]A1=48 ft * 64 ft = 3,072 \ ft^2[/tex]

The area of the small blue rectangle is:

[tex]A2=28 ft * 20 ft = 560\ ft^2[/tex]

The area of the store is:

[tex]As=A1-A2=3,072 \ ft^2- 560\ ft^2=2,512 \ ft^2[/tex]

Rounding to the nearest 50 square feet:

[tex]\boxed{As=2,500 \ ft^2}[/tex]

Correct choice D. 2,500 square feet

Answer:

60 x 4 = 240 times

Step-by-step explanation:    

In every hour there are 60 minutes.

That means for every hour the minute hand moves 60 times

Take the amount of hours and times it by 60 ( Hours x 60 )

The minute hand of the clock completes 4 rotations as it moves from 12:00 noon to 4:00 p.m

In a clock there are second hand, minute hand and hour hand, all rotates anticlockwise. If the minute hand come at the same place after start rotating from that place , then the rotation is called one complete rotation.

Since 1 complete rotation of a minute hand takes 60 minutes, which is one hour.

Therefore, In one hour the minute hand completes one rotation.

Thus, after first complete rotation of minute hand the time will be 1:00 p.m.

After two complete rotation of minute hand the time will be 2:00 p.m.

After three complete rotation of  minute hand the time will be 3:00 p.m.

Similarly, after four complete rotation of minute hand the time will be 4:00 p.m.

Hence it takes 4 complete rotation of a minute hand to moves from 12:00 noon to 4:00 p.m.
