Answer:

The speed is 900,000,000 km/h

Step-by-step explanation:

The ratio of distance covered to time taken gives the speed of an object

[tex]Speed, \ v = \dfrac{Distance, \ d}{Time, \ t}[/tex]

Given that the distance covered, d = 5 × 10⁵ cm

The time to travel the given distance, t = 2 × 10⁻⁵ seconds

Therefore;

[tex]Speed, \ v = \dfrac{5 \times 10^{5} \ cm}{2 \times 10^{-5} \ s} = 2.5 \times 10 ^{10} \ cm/s[/tex]

In km/h, we have;

1 cm = 0.00001 km

∴ v = 2.5 × 10¹⁰ cm/s × 1 km/(100,000 cm) × 3,600 s/h = 900,000,000 km/h

The speed is 2.5 × 10¹⁰ cm/s or 900,000,000 km/h.

The statement which says that the measure of ∠ABD = ¹/₂ ∠ABC. So, the correct option is C.

An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.

A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.

For the given case,

Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.

Answer:

Option A and E.

Step-by-step explanation:

It is mentioned that Chiyo has a toolbox having a  rectangular prism shape with a length of 8 inches, width of 15 inches, and height of 6 inches.

In addition to this, A triangular prism with a triangular base with base 8 inches and height 3 inches. The prism has a height of 15 inches.  

So here the shape can be broken into a triangular prism and rectangular prism

Therefore the first option is correct

Now as we know that

Volume of the rectangular prism is

= l×b× h

= 8 × 15 × 6

= 720

And, the volume of the triangular prism is bh

And, the area of the triangular prism is 1 ÷ 2 × b × h

= 1 ÷ 2 × 8 × 3

= 12

Now the volume is

= 12 × 15

= 180

So, the volume of the tool box is

= 720 + 180

= 900

Hence, the last option is correct  

Answer:

Angle of elevation from the duck is [tex]59.7^{o}[/tex]

Step-by-step explanation:

This description can be represented by the three sides of a triangle and the given angle. Let the angle required be represented by θ. Thus applying the appropriate trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

So that,

Tan θ = [tex]\frac{12}{7}[/tex]

          = 1.7143

θ = [tex]Tan^{-1}[/tex] 1.7143

  = 59.7438

θ = [tex]59.7^{o}[/tex]

The angle of elevation from the duck is determined as [tex]59.7^{o}[/tex].
