Answer:

10 Km/h

Step-by-step explanation:

Let the speed of the container ship be y

The speed of the aircraft = y + 5

Next, we shall determine the time taken by the aircraft to travel 450 Km. This can be obtained as follow:

Speed of aircraft (Sₐ) = y + 5

Distance travelled (dₐ) = 450 Km

Time for aircraft (tₐ) =?

Speed = distance / time

Sₐ = dₐ / tₐ

y + 5 = 450 / tₐ

Cross multiply

(y + 5) × tₐ = 450

Divide both side by (y + 5)

tₐ = 450 / (y + 5)

Finally, we shall determine the speed of the carrier. This can be obtained as follow:

Speed of container ship (S꜀) = y

Distance travelled (d꜀) = 300 Km

Time for container ship (t꜀) = Time for aircraft (tₐ)

Time for aircraft (tₐ) = 450 / (y + 5)

t꜀ = tₐ

t꜀ = 450 / (y + 5)

Speed = distance / time

S꜀ = d꜀ / t꜀

y = 300 ÷ 450 / (y + 5)

y = 300 × (y + 5) / 450

y = (300y + 1500) / 450

Cross multiply

450y = 300y + 1500

Collect like terms

450y – 300y = 1500

150y = 1500

Divide both side by 150

y = 1500 / 150

y = 10 Km/h

Thus, the speed of the container ship is 10 Km/h.

Answer: SP is Rs 690

Step-by-step explanation:

CP= Rs 750

loss percent = 8%

so

loss = 8% of CP

= 8/100 * 750

= Rs 60

Loss = Rs 60

so

SP = Rs 750-60

= Rs 690

Answer:

here,

CP=750

loss%=8%

now,

SP= (100-L)×cp/100

= (100-8)×750/100

= (92×750)/100

= 69000/100

= 690

hence the SP of the article is Rs 690

Answer:

g = At/60

Step-by-step explanation:

A = 60(g/t)

To solve for 'g'

Open the bracket

A = 60g/t

Multiply both sides by t

At = 60g

Divide both sides by 60

At/60 = 60g/60

At/60 = g

Answer: Hello your question lacks vital information attached below is the vital information

Along with the image below, Use your knowledge of the unit circle and radian measure of angles to answer the following questions. [Note: When the questions ask you to consider circles and their angle in relation to the main circle, the question is referring to the location of the center of each circle.]

answer:

Circle 7 = π / 4

Circle 8 = 7π / 12

Circle 9 = 11 π / 12

Circle 10 = 5π / 4

Circle 11 = 19π / 12

Circle 12 = 23π / 12

Step-by-step explanation:

Given that 45° = π/4.

∴  All the six(6) circles ( 7 through 12 ) are separated by : 60° = π/3

The Radian measure of the remaining circles through 12 :

Circle 8 = π/3 + π /4 = 7π / 12

Circle 9 = π/4 + 2 π/3 = 11 π / 12

Circle 10 = 5π / 4

Circle 11 = 19π / 12

Circle 12 = 23π / 12

Reason : All the six(6) circles ( 7 through 12 ) are separated by : 60° = π/3

Answer: 24(option A) is the answer

exterior angle = 360/n

so, n = 15

then, 360/15 = 24

Answer:

20 is the answer

Step-by-step explanation:

x+3x+10=90(right angle triangle)

4x=90-10

x=80/4

x=20°

Answer:

x = 20

Step-by-step explanation:

Based on the square indication at the corner of the angle, we can assume it's a right angle, so 90°. This means that x + 3x + 10 = 90. Solve it like any algebraic equation, isolating x. add x to 3x + 10, this would net you 4x + 10 = 90. Subtract 10 on both sides of the equation to further isolate x, meaning 4x = 80. Simplify this, dividing 4 on both sides, meaning x = 20.

=========================================================

Work Shown:

SA = surface area of the rectangular prism (aka block or box)

SA = 2*(LW + LH + WH)

SA = 2*(8*3 + 8*1 + 3*1)

SA = 2*(24 + 8 + 3)

SA = 2*(35)

SA = 70 square feet

This is the amount of wrapping paper you would need to cover all six sides of the box. This assumes that there are no gaps or overlaps.

Answer:

~ 220.6

Step-by-step explanation:

sine rule : a/sinA =b/sinB = c/sinC

AB/sinC =BC/sinA

A = 180 - 110.2 - 13.5 = 56.3 degrees

AB/sin13.5 = 786/sin56.3

AB = 786sin13.5/sin56.3 = 220.5506

The distance across the river of AB is 220.55 m.

Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.

That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,

a / sin A = b / sin B = c / sin C

Given a triangle ABC.

We have,

∠B = 110.2° and ∠C = 13.5°

We know that the sum of the interior angles of a triangle is 180°.

∠A = 180 - (110.2 + 13.5) = 56.3°

Using the law of sines,

BC / Sin A = AB / Sin C

Substituting the values,

786 / sin (56.3°) = AB / sin (13.5°)

AB = (786 / sin (56.3°)) sin (13.5°)

     = 220.55 m

Hence the distance is 220.55 m.
