A disc has a diameter of centimeters while a mini disc has a diameter of centimeters. Write the ratio of the mini disc diameter

Dafna1 [17]

Answer:

2 : 3

Step-by-step explanation:

A disc has a diameter of 21 cm while a mini disc has a diameter of 14cm. Write the ratio of the mini disc diameter to the disc diameter.

Answer: Let the diameter of the mini disc be $d_1$ while the diameter of the disc be $d_2$ . To get the ratio of the mini disc diameter to the disc diameter, we just simply have to divide the diameter of the mini disc by the diameter of the disc and then represent the fraction in ratio form. The ratio of the disc diameters is given by:

Ratio of the mini disc diameter to the disc diameter = Diameter of mini disc / diameter of disc

Ratio of the mini disc diameter to the disc diameter = $\frac{14}{21}=\frac{2}{3}$

Ratio of the mini disc diameter to the disc diameter = 2 : 3

What is the measure of angle BCD? m∠BCD = degrees

ratelena [41]

Angle DAC = 180-25 = 155 degrees
Angle ABC = 180 - 146 = 34 degrees
Angle ADC = 180 - 149 = 31 degrees

ABCD is a quadrilateral and angles in quadrilateral add up to 360 degrees

Angle BCD = 360 - (155 + 34 + 31)
= 360 - 220
= 140 degrees

The building of the Blue Museum of Barcelona is triangular. Each side of the building is 180 m. How far do we have to travel to

Sever21 [200]

Answer:

540 m

Step-by-step explanation:

The building of the Blue Museum of Barcelona is triangular and each side of the building is 180 m.

This means the building is shaped as an equilateral triangle.

We need to find the total distance traveled if we go round the building, that is, its perimeter.

The perimeter of an equilateral triangle is given as:

P = 3L

where L = length of the side of the building = 180 m

The total distance traveled if we go round the building will be:

P = 3 * 180 = 540 m

We would need to go 540 m to travel around the building completely.
