the answer is 2 years

Step-by-step explanation:

v+27°+4v+39+11v=180°

v+4v+11v+27°+39°=180°

16v+66=180°

16v=180°-66

16v=114

16v÷16=114÷16

The team's time on their final run is 4.31 minutes.

According to the question,

We have the following information:

Their first run takes 4.85 minutes. On each of the next two runs, the team's time changes by -0.27 minute compared to the previous time.

Now, the second run will be 0.27 minutes less than 4.85 minutes.

Time for the second run = 4.58 minutes

Now, the third run will be the final run and 0.27 minutes less than the previous run.

Now, the time for the final run will be as given below:

4.58-0.27

4.31 minutes

Hence, the team's time on their final run is 4.31 minutes.

Answer: 50, 99

Step-by-step explanation:

we just have to substitute the values of x and y in the given expressions.

7(2)+4(9)=50

4(9)+7(9)=99

Answer:

Step-by-step explanation:

7x + 4y= 50 and 4y + 7y= 99

Since, x=2 and y=9

7x + 4y= 7*2 + 7*9= 14 + 36= 50

For the image 1, the angular values are x=9⁰ and y=23⁰

For the image 2, the angular values are x=9⁰ and y=14⁰

An angle is a figure in Euclidean geometry made up of two rays that share an endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. Dihedral angles are what they are. A measure of an angle or of a rotation is also referred to as an angle. The ratio of a circular arc's length to radius is known as this quantity. A geometric angle's arc is centered at the vertex and is bound by its sides.

For the first image x and y values are,

As from the given figure,

(4y-2)⁰=90⁰

4y=90+2

y=92/4

y=23⁰

3x-6=21⁰

3x=27

x=9⁰

Therefore, x=9⁰ and y=23⁰

For the second image x and y values are,

The missing measure is  ∠P =∠X = 122°

Given △ACP ≅ △LNX

AC = 21 cm, m∠C = 29°

PC = 13 cm, m∠Y = ??  (there is no angle Y)

On the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.

PA = PC = XL = XN = 13 cm

In the same way, ...

LN = AC = 21 cm

Of course, the angles have a similar relationship:

∠A = ∠C = ∠L = ∠N = 29°

The two base angles in the triangle add to 58°, so the third angle is ...

180° -58° = 122°

∠P =∠X = 122°

As is often the case in over-specified problems, the numbers shown are not consistent. The length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified.

Answer:The value of cos 60 degrees can be calculated by constructing an angle of 60° with the x-axis.

Step-by-step explanation:

Then finding the coordinates of the corresponding point (0.5, 0.866) on the unit circle.
The value of cos 60° is equal to the x-coordinate (0.5).
     ∴ cos 60° = 0.5.

The value of cos 60° using trigonometric ratio  is 1/2 or 0.5 .

What is trigonometric ratios?

There are six trigonometric ratios used in trigonometry: sine, cosine, tangent, secant, and cotangent. The abbreviations for these ratios are sin, cos, tan, sec, cosec(or csc), and cot. Look at the below-displayed right-angled triangle. Any two of the three sides of a right-angled triangle can be compared in terms of their relative angles using trigonometric ratios.

Here , the given is ,

=> cos60°

Since the cosine function is a periodic function, we can represent cos 60° as, cos 60 degrees = cos(60° + n × 360°),

Then

=> Cos 60° = 1/2 = 0.5.

Hence the value of cos 60° is 1/2 or 0.5.

Using the straight line method, the depreciation expense in year 1 and 2 is $14,000.

Using the double declining method, the depreciation expense in year 1 is  $29,600 and $17,760 in year 2.

Using the unit of production method, the depreciation expense in year 1 is $18,000 and $19,000 in year 2.

The straight line depreciation method is a depreciation method in which the the depreciation amount each year of the asset's useful life is the same.

Straight line depreciation = (cost of the asset - salvage value) / useful life

Cost of the asset = $70,000 + $3000 + $1000 = $74,000

Straight line depreciation = ($74,000 - $4,000) / 5  = $14,000

The double declining method entails depreciating an asset at twice the rate of the straight line method.

Depreciation expense = cost of the asset x depreciation factor

Depreciation factor = 2 x (1/useful life)

Depreciation expense in year 1 = (2 /5) x  $74,000 = $29,600

Book value in year 2 = $74,000 = $29,600  = $44,400

Depreciation expense in year 2 = (2 /5) x  $44,400 = $17,760

The depreciation in the unit of production method depends on the output of the machine each year.

Depreciation = (output in a year / total output) x (cost of the asset - salvage value)

Depreciation in year 1 = ($74,000 - $4,000) x (36,000 / 140,000) = $18,000

Depreciation in year 2 = ($74,000 - $4,000) x (38,000 / 140,000) = $19,000
