there are 360 degress in a circle if you cut a circle in half at its center aka its diameter the center angle would be 180 degree or a straight line 360/2 180 and a circle divide into 2 sectors so your questoin would be equal algebraically to 360x=30 360 is the totatal number degrees in every circle 30 is the resulting degree and x is the length of each of the sectors if you solve yo get 1/12 thus total sectors would be 12

if the humpback whales had traveled at the same rate for 32 days,how many more miles would the have traveled than the grey whale
Nataliya [291]

Answer:

192 miles more than the gray whales.

Step-by-step explanation:

first, get the rate of each whale per day. To put it in simpler terms, divide 2,240 miles by 28 to find how much the humpback whales travel in a day. next, do the same for the gray whales. I got that the humpback whales traveled 80 miles in a day and the gray whales traveled 74 in a day. Multiply 80 miles by 32 days to get the distance the humpback whales travel in 32 days (2,560 miles). Since you know the distance the Gray whales traveled in 32 days, you do not need to solve for it. Subtract 2,560-2,368 and you get 192 miles.


Hope this helped. If you can, label this answer as brainliest. Dont hesistate to ask if you have any questions. <3

kkurt [141]
Hello

Answer: The ratio of the first 6 months to the last 6 months is 0.765.
First, we need to determine the amount of money they had in each 6 month period.
In the first 6 months they had: 6 x 76500 = 459000
In the second 6 months they had: 6 x 100000 = 600000
Divide the 2 values to find the ratio:  459000 / 600000 = 0.765

speed=distance /time-------> time=distance/speed
1/y=2.5/x-------> y=x/2.5------> x=2.5y-------> equation 2

equals 1 and 2
6+y=2.5y-----> 2.5y-y=6------> 1.5y=6-----> y=6/1.5-----> y=4 mi/h
x=6+y-----> x=6+4-----> x=10 mi/h

the answer is
the speed walking is 4 mi/h
