Answer:
$3.3
Step-by-step explanation:
To find how much a single cople costs divide 1.1/20=11/200
Then, to find how much money for 60 coples, multiply the amount of money for one cople by 60: (11/200)(60)=
33/10 0r $3.3
Hope this helps! :)
<span>Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore,
</span>1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)
= (3600/57.1) mi/hours
<span> = 63.047 mi/hours</span>
Answer:
62
Step-by-step explanation:
By the outside angle theorem, r is equal to the difference of the two arcs over 2.
We know the first arc is 242. We can find the second arc by subtracting that from 360.
So we have the seconds are is 118.
242-118 = 124
124/2 = 62
Base of pyramid, a = 756 ft
= 252 yards (1 ft = 0.333 yards)
Height of pyramid, h = 480 ft
= 160 yards
(a). For a square pyramid, we have:
Volume =
=
= 33,86,880 cubic yards
Hence, volume of the Great Pyramid = 33,86,880 cubic yards
(b). Volume of limestone block = 1.5 cubic yards
Number of limestone blocks needed to construct the Great Pyramid = Volume of pyramid / volume of limestone block
= 33,86,880 / 1.5
= 22,57,920 limestone blocks
