solve:
2sinxcosx=0.5

Answer:

2

Step-by-step explanation:

4x+3−x=12x−15

Combine 4x and −x to get 3x.

3x+3=12x−15

Subtract 12x from both sides.

3x+3−12x=−15

Combine 3x and −12x to get −9x.

−9x+3=−15

Subtract 3 from both sides.

−9x=−15−3

Subtract 3 from −15 to get −18.

−9x=−18

Divide both sides by −9.

x= –18÷–9

Divide −18 by −9 to get 2.

x=2

The thickness of the sheet of paper in nanometre is 50,000

The sheet of paper is 0.00005 meter thick .

1 nanometre = 1 × 10⁻⁹ meters

1 × 10⁻⁹ meters = 1 nanometre

0.00005 meters = ?

cross multiply

Therefore,

Thickness of the paper (nanometre) = 0.00005/1 × 10⁻⁹

Thickness of the paper(nanometre) = 50,000

Using the information given in the table, and the speed - time relationship, the solutions to the exercises goes thus :

Using the information given in the table :

1.) The winning time for last year's race will be the lowest time on the table. Using the winning time column, the winning time for each city is :

2.)

The winning time of past winners cannot be determined as the exact distances of each city isn't given.

3.)

The information required to calculate speed is distance and time ;

4.)

Distance = 1000/5 = 200 ft/min

5.)

Speed in Knots ;

Speed in feets per hour

200 ft/ min × 60/1 hour = 12000 feets per hour

Speed in nautical mile per hour

(12000 ft/hr) × (1/6076)feets = 1.975 nautical miles per hour

Therefore, speed in knots is 1.975 knots.

Answer:

the answer to x is 15 degrees

Answer:

x = 15

Step-by-step explanation:

these two labeled angles are supplementary because they are same-side interior angles

we can add them together and set the sum equal to 180 to find 'x'

3x - 15 + 150 = 180

combine -15 and 150 to get 135

3x + 135 = 180

subtract 135 from each side to get:

3x = 45

divide each side by 3 to get:

x = 15

The length of the other parallel side is 10 cm.

Trapezium is a quadrilateral (has four sides and four angles) with a pair of parallel sides. The area (A) of a trapezium is given by:

A = (1/2)(a + b)h

where a and b are the length of the parallel sides, h is the height of the trapezium

Given A = 54, a = 8 cm, h = 6 cm, hence:

54 = (1/2)(8 + b)6

8 + b = 18

b = 10 cm

The length of the other parallel side is 10 cm.

[tex]x=13[/tex]

[tex]y=23[/tex]

Step-by-step explanation:

[tex](12x - 41) + 5x = 180[/tex]

[tex]12x + 5x = 180 + 41[/tex]

[tex]17x = 221[/tex]

[tex] \frac{17x}{17} = \frac{221}{17} [/tex]

[tex]x = \frac{221}{17} [/tex]

[tex]x = 13[/tex]

[tex](12 \times 13 - 41) + 5(13) = 180[/tex]

[tex]115 + 65 = 180[/tex]

[tex]180 = 180[/tex]

[tex]vertical \: angles[/tex]

[tex](12x - 41) = 5y[/tex]

[tex]12 \times 13 - 41 = 5y[/tex]

[tex]115 = 5y[/tex]

[tex] \frac{115}{5} = \frac{5y}{5} [/tex]

[tex]y = \frac{115}{5} [/tex]

[tex]y = 23[/tex]

[tex]5y=12x-41[/tex]

[tex]5×23=12×13-41[/tex]

[tex]115=115[/tex]

We can use the two terms in x to find the value of x.

Angles on a line have a sum of 180°

⇒    (12x -41)° + 5x° = 180°

⇒    (12x + 5x -41)° = 180°

⇒                    17x° = 180 + 41°

⇒                       x = 13

We can use the same principle of angles to find y

                      5x° + 5y° = 180°

since x = 13;  5(13) + 5y = 180

                                 5y = 115

                                   y = 23

Answer:

[tex]59.6[/tex] mm

Step-by-step explanation:

We know that the base times the height divided by two is the area, so we have that [tex](8.6*h)/2=256.28[/tex].

We can multiply both sides by [tex]2[/tex] to get [tex]8.6*h=512.56[/tex].

Lastly, we divide by [tex]8.6[/tex] on both sides to get [tex]h=512.56/8.6[/tex].

This simplifies to [tex]\boxed{h=59.6}[/tex] mm!
