How much time does it take for a bird flying at a speed of 45 kilometers per hours to travel a distance of 1,800 kilometers

Mathematics
1 answer:
____ [38]4 years ago
4 0

Step-by-step explanation:

This is simply a case of division. since you already know that the bird is flying at 45 kilometres per hour, you should be able to devise that every hour the bird is going 45km

we are gonna use ratio for this

1:45

?:1800

first of all divide 1800 by 45, to find the number you are gonna multiply the other number by, secondly multiply ur answer by 1 since that is the number of hours it takes to for the bird to travel 45km, after u have suceeded in doing this, you already have ur answer which is 1800 divide by 45 times 1

2x + 3y = 15 and x - 3y = 3 What's the ordered pair
Ganezh [65]

Answer:

x = 6

y = 1

Step-by-step explanation:

to solve this system of equation we say let

2x + 3y = 15 .......................... equation 1

x - 3y = 3.................................. equation 2

from equation 2

x - 3y = 3.................................. equation 2

x = 3 + 3y.................................... equation3

substitute for x in equation 1

2x + 3y = 15 .......................... equation 1

2(3+3y) + 3y = 15

6 + 6y + 3y = 15

9y = 15 -6 ................................... combining the like terms

9y = 9

divide both sides by the coefficient of y

9y/9 = 9/9

y =1

put y = 1 in equation 3

x = 3 + 3y.................................... equation3

x = 3 + 3(1)

x = 3 +3

x = 6

therefore the value of  x is 6 and y is 1 respectively

Find the length of the arc<br> A.8 pie ft<br> B.32 pie ft<br> C.64 pie ft<br> D. 361 pie/ 12 ft
ExtremeBDS [4]
<h3>Answer: Choice A. 8pi  feet</h3>

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

Explanation:

The perimeter around the circle is known as the circumference

The full circumference of a circle with radius r is

C = 2*pi*r

In this case, r = 16 is the radius, so,

C = 2*pi*r

C = 2*pi*16

C = 2*16*pi

C = 32pi

is the full distance around the circle. But we only want 90/360 = 1/4 of that total distance. So take 1/4 of 32pi to get

(1/4)*32pi = (1/4*32)pi = 8pi

The arc length is exactly 8pi feet long

Approximately this is about 25.13274 feet
