The length of the ramp calculated using Pythagoras is approximately 350 cm

From the diagram attached :

  • Height of ramp = opposite = 225 cm

  • Angle of inclination, θ = 40°

Using Pythagoras ; the length of the ramp can calculated as follows :

Sin θ = opposite / hypotenus

Sin 40° = 225 / hypotenus

Cross multiply

Hypotenus × 0.6427876 = 225

Divide both sides by 0.6427876 to isolate the hypotenus

Hypotenus = 225 / 0.6427876

Hypotenus = 350.03786 cm

Therefore, the length of the ramp which is the hypotenus is approximately 350 cm

If a/b = c/d, then ad = bc.
Nikolay [14]

Answer:

The statement is true

see the explanation

Step-by-step explanation:

we have the proportion

\frac{a}{b}=\frac{c}{d}

we know that

To solve the proportion multiply in cross

so

(a)(d)=(b)(c)

ad=bc

therefore

An animals heart beats 80 beats per minute how many minutes does it take to beat a million times?
Klio2033 [76]

The key calculation in this problem is figuring out <em>how many times 80 goes into 1,000,000</em>. I'll build up in steps here.

80 x 5 = 400. This gives us a building block on our way to 1,000,000. From here, we can go further and say that 400 x 5 = 2,000; that 2,000 x 5 = 10,000; and finally that 10,000 x 100 = 1,000,000. Altogether, starting from 80, that's

80 x 5 x 5 x 5 x 100 = 80 x 25 x 500 = <em>80 x 12,500</em>

So, since 80 goes into one million 12,500 times, it takes 12,500 minutes for the animal's heart to beat that 1,000,000 times.

ABC is a right angled triangle right angled at B . A circle with centre O inscribed in the triangle . AB=6CM BC=8CM . Find the r
Vikki [24]

Answer:

Radius = 2 cm.

Step by step explanation:

By the Pythagoras theorem  the third side of the triangle

= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.

The formula for the radius of the circle is

r = sqrt [ (s - a)(s-b)(s-c)/ s ]  where a,b,c are side lengths and s = the semi perimeter.

Here s = ( 6+8+10) / 2 = 12

So the radius r  

= sqrt [ (12-6)(12-8)(12-10)/ 12 ]

= sqrt 4

= 2 (answer).
