Answer:

AB is on the latitude 30°N.

Find AB:

AB = 2*3.142*6400*cos 30°*(32+35)/360 = 6482.15 km

BC is along longitude 35°W

Find BC:

BC = 2*3.142*6400*(30 + 20)/360 = 5585.77 km

Total distance traveled:

6482.15 + 5585.77 = 12067.92 km

Convert the distance to nautical miles:

12067.92/1.86 = 6488.13 nautical miles

Find the average speed:

6488.13/22 = 294.92 nautical miles / hour

Note. This is unrealistically high speed for a ship, this must be a plane or the time given wrong.

If l=3, w= 3, and h= 5, what is the volume of this box

ArbitrLikvidat [17]

Answer and Step-by-step explanation:

To find the volume, we multiply the length by the width by the height for a rectangular prism (aka the box).

length = l = 3

width = w = 3

height = h = 5

Now, we multiply each together.

3 × 3 × 5

9 × 5

The volume of the box is 45.

Clare knows that Priya has a bunch of nickels and dimes in her pocket and that

enyata [817]

Answer:

a) 21 nickels and 2 dimes

b) $5x+10y=125$

c) There are 13 nickels and 6 dimes

d) The point (13,6) a solution to the equation you wrote

Step-by-step explanation:

Let x be the number of nickels and y be the number of dimes in Priya's pocket.

1 nickel = 5 cents

x nickels = 5x cents

1 dime = 10 cents

y dimes = 10y cents

b. Total amount in nickels and dimes is $5x+10y$ cents that is $1.25. Convert $1.25 into cents:

$\$1.25=125\ cents,$

so the equation that describes the relationship between the number of dimes and number of nickels is

$5x+10y=125$

a. To find one possible solution, substitute an arbitrary value of y and find x. Let y = 2, then

$5x+10\cdot 2=125\\ \\5x+20=125\\ \\5x=125-20\\ \\5x=105\\ \\x=21$

21 nickels and 2 dimes

c. The point (13,6) means that there are 13 nickels and 6 dimes.

d. Substitute x = 13 and y = 6 intoe the equation and check whether it is true:

$5\cdot 13+6\cdot 10=65+60=125$

True, so the point (13,6) a solution to the equation you wrote

Rina wants to ride the bumper cars 1 time and the Ferris wheel 5 times. It costs 1 ticket to ride the bumper cars and 1 ticket t

Lana71 [14]

Answer:

Rina will need 6 tickets.

Explanation:

Rina needs only 1 ticket to ride the ferris wheel once, and 1 ticket to ride the bumper cars once. If she wants to ride the ferris wheel 5 times, then she'll need 5 tickets since 1 x 5 = 5. If she wants to ride the bumper cars only once, she'll only need 1 ticket since 1 x 1 = 1.

Add the answers together, and you get 6 tickets since 5 + 1 = 6.

Hope this helps! :)
