Answer:
308m²
Step-by-step explanation:
[(7*6)/2]*4= 84
(3*6)*2=36
(3*5)*2=30
8*6=48
[(2*14)+(3*5)]2=(28+15)2=43*2=86
(2*6)*2=24
84+36+30+48+86+24=308m²
Answer:
2/3y
Step-by-step explanation:
If the class usually has y students and has 2/3 today, it can be represented by 2/3y.
Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.
So, in terms of y, 2/3y represents the number of students in class today.
To answer this you will need to write the ratio of difference in the tides over the amount of time that goes by.
1. 3.21 ft - 0.20 ft= 3.01 ft change.
2. 3.01 change over 6 5/12 hr.
3. Divide these to find the lapse rate per hour. This is about 0.47 ft per hour.
Circumference's formula is: 2πr
Since π is not added in the total (as it is 28π), just divide 28 with 2 to get r
28/2 = 14
The radius is 14
hope this helps
