Answer:

0.548

Step-by-step explanation:

5 x 0.1 = 0.5

4 x 0.01 = 0.04

8 x0.0001 = 0.008

Now add them all together to get 0.548 in standard form.

I hope this helps! :)

Answer:

5 × 0.1 is 0.5

4 × 0.001 is 0.04

8 × 0.0001 is 0.008

so add all number is

0.548

Hi ;-)

[tex]u+51^o=79^o\\\\u=79^o-51^o\\\\\huge\boxed{u=28^o}[/tex]

The required equation is,

→ 51° + U = 79°

Now we should,

find the required value of U.

→ 51° + U = 79°

→ U = 79° - 51°

→ [U = 28°]

Let's check whether the required value of U is correct or incorrect,

→ 51° + U = 79°

→ 51° + 28° = 79°

→ 79° = 79°

→ LHS = RHS

Hence, 28° is the required value of U.

The area of a figure is the amount of space the figure can occupy. [tex]18a^4 + 10[/tex] of the door will be made from the wood.

Given

[tex]Length = 6a^2 + 2[/tex]

[tex]Width = 3a^2 + 5[/tex]

First, calculate the area of the rectangular door

[tex]Area = Length \times Width[/tex]

[tex]Area =(6a^2 + 2) \times ( 3a^2 + 5)[/tex]

[tex]Area = 18a^4 + 6a^2 + 30a^2 + 10[/tex]

[tex]Area = 18a^4 + 36a^2 + 10[/tex]

Next, calculate the area of the glass panel

The dimension of the glass panel is not given, and the diagram is not attached. So, I will assume the dimension of the square glass panel is [tex]6a[/tex].

So, the area of the glass panel is:

[tex]Area = 6a \times 6a[/tex]

[tex]Area = 36a^2[/tex]

To calculate how much wood that will be needed for the rectangular door, we simply subtract the area of the glass panel from the area of the door

[tex]Wood = 18a^4 + 36a^2 + 10 - 36a^2[/tex]

Collect like terms

[tex]Wood = 18a^4 + 10 + 36a^2 - 36a^2[/tex]

[tex]Wood = 18a^4 + 10[/tex]

Considering the assumed value, [tex]18a^4 + 10[/tex] of the door will be made from the wood.

t=4x+c

Since we are looking for x,

t-c=4x

Divide through by the coefficient of x which is 4

4x/4=t-c/4

Therefore, x=t-c/4

Answer:

X should equal 12.

Step-by-step explanation:

I say this because we know TED= 30° bc 50°-20° = 30

then u have to think about what × 2 + 6 equals 30

sure enough 12 × 2 = 24 and 24 + 6 = 30

that's why I say X equals 12

Answer:

C.(CCCXLIII)

Step-by-step explanation:

The aspect ratio represents the ratio of the width to the height of a television.  

The size of a TV is calculated using Pythagoras theorem. Assume the length ratio of the older 25-inch [tex]4:3[/tex] TV is x.

The ratio is represented as:

[tex]Width : Height = 4:3[/tex]

Using Pythagoras theorem, we have:

[tex]Width^2 + Height^2 = 25^2[/tex]

[tex](4x)^2 + (3x)^2 = 25^2[/tex]

[tex]16x^2 + 9x^2 = 625[/tex]

[tex]25x^2 = 625[/tex]

Divide both sides by 25

[tex]x^2 = 25[/tex]

Take positive square roots

[tex]x = 5[/tex]

So, the height of the image is:

[tex]Height = 3x[/tex]

[tex]Height = 3 \times 5 = 15[/tex]

While the width is

[tex]Width = 4x = 4 \times 5 = 20[/tex]

Hence, the height of the image is 15 inches

The height of each black bar is calculated as follows:

[tex]Width : Height = 2.35 : 1[/tex]

Where

[tex]Width = 20[/tex]

So, we have:

[tex]20 : Height = 2.35 : 1[/tex]

Express as fraction

[tex]\frac{Height}{20} = \frac{1}{2.35}[/tex]

Make Height the subject

[tex]Height = \frac{20}{2.35}[/tex]

[tex]Height = 8.51[/tex]

The height of each black bar at the top and at the bottom is 8.51 inches

The percentage of the screen’s area that is occupied by the image is calculated using

[tex]\% Screen = \frac{A_1}{A_2} \times 100\%[/tex]

Where

[tex]A_1 \to[/tex] Area of black bars

[tex]A_2 \to[/tex] Area of the 25-inch 4:3 television

So, we have:

[tex]A_1 =8.51 \times 20 = 170.2[/tex]

[tex]A_2 =15 \times 20 = 300[/tex]

[tex]\% Screen = \frac{A_1}{A_2} \times 100\%[/tex] becomes

[tex]\% Screen = \frac{170.2}{300} \times 100\%[/tex]

[tex]\% Screen = \frac{170.2}{3} \%[/tex]

[tex]\% Screen = 56.73 \%[/tex]

Hence, the percentage of the screen area occupied is 56.73%

Consumers moved to TV with a wide screen because a TV with wide screen shows bigger pictures than smaller dimension TV screens,

When the pictures are bigger, the consumers will have a clearer view of what they're watching.

Answer:

x=11

y=3

Step-by-step explanation:

(9x+25)=(13x-19)

9x+25 = 13x−19

9x+25-25 = 13x−19-25

9x=13x-44

9x-13x=13x-44-13x

-4x= -44

x=11

y= 180-(9x+25)

y= 180-(99+25)

y= 180-124 = 56

y= 56-5 = 51

y= 51/17

Answer:

1078 minutes

Step-by-step explanation:

18 + 0.05x = 71.90

0.05x = 71.90 - 18

0.05x = 53.9

x = 53.9/0.05

x = 1078 minutes

The minimum number of minutes is 1078 minutes.

To find the minimum number of minutes she has used on her phone in a month.

The branch of mathematics dealing with the properties and manipulation of numbers.

Given that :

Halima pays a monthly fee of 18 AED and she pays an additional 5 files per minute of use. The least she has been charged in a month is 71.90 AED.

so, that

18 + 0.05x = 71.90

0.05x = 71.90 - 18

0.05x = 53.9

x = 53.9/0.05

x = 1078 minutes

So, the minimum number of minutes is 1078 minutes.
