Determine whether the two triangles are similar and, if they are similar, state a reason.

Mathematics
1 answer:
aleksley [76]2 years ago

Answer:

Step-by-step explanation:

By triangle sum theorem,

Sum of interior angles of a triangle is 180°.

Therefore, measure of third angle in the larger triangle = 180° - (35° + 120°) = 25°

Similarly, measure of third angle in the smaller triangle = 180° - (25° + 120°)

= 35°

Since, measure of interior angles of larger triangle is equal to the measure of smaller triangle,

Both the triangles will be similar by AA property of similarity.

Dr yang buys a violin for £13200 plus vat at 20% dr yang pays a deposit for the violin he then pays the rest of the cost in 12 e
Andre45 [30]

Answer:

8/3

Step-by-step explanation:

Given that:

Cost of violin = 13200 plus VAT at 20%

Cost of violin = (100 + 20)% * 13200

Cost of violin = 1.20 * 13200 = £15,840

Instalment pay = (360 * 12) = 4320

Therefore, deposit made equals ;

Total cost - Instalment pay

£(15,840 - 4320) = £11,520

Hence, ratio of deposit made to the total Instalment payment made ;

£11520 / £4320 = 8 / 3

In four years, 40% of a radioactive element decays. Find its half-life. Round to one decimal place.
White raven [17]

To find the answer, use k = \frac{2.303 }{ 4} (log\frac {100 }{ 40}) , and then use the equation t=\frac{.693}{k} To find it's half life.

Describing Function Notation of a Scenario
san4es73 [151]

Answer:

v(h) represents the volume of the water (ft³) in the pool at h hours

h is the number of hours

When h increased v(h) decreased

Step-by-step explanation:

- A swimming pool has about 603 cubic feet of water

∴ The volume of the water in the pool initially is 603 feet³

- The pool liner has a small hole and is leaking at a rate of 15  cubic

   feet each hour

∴ The rate of decreasing of the volume of the water in the pool is

   15 feet³ per hour

- The volume of the the water v at a time h hour can represented by

  a linear function v(h)

∴ v(h) = -15 h + 603 , where v(h) is the volume of the water in the

   pool in cubic feet at h hour

- Let us put an example to understand the relation between v(h)

  and h

- Assume that h = 0

∵ h = 0

∴ v(0) = -15(0) + 603

∴ v(0) = 603 ft³ ⇒ The volume of the water at the beginning

- Assume that h = 2 hours, that means we need to know the volume

  of the water after two hours

∵ h = 2 hours

∴ v(2) = -15(2) + 603

∴ v(2) = -30 + 603 = 573 ft³

∵ h increased from 0 to 2

∴ v(t) decreased from 603 ft³ to 573 ft³

∴ The volume decreased when the number of hours increased

* v(h) represents the volume of the water (ft³) in the pool at h hours

* h is the number of hours

* When h increased v(h) decreased
