Answer: 1 hour
Step-by-step explanation:
1st trip = 4mph
12 mi / 4 mi
12 mi = 3 hrs
2nd trip = 6 mph
12 mi / 6 mi
12 mi = 2 hrs
3hrs - 2 hrs = 1 hr
To organize 169 students in a square formation, we find the square root of 169, which is 13, so there should be 13 students in each row.
The question pertains to arranging 169 students in a square formation for a photo. When we arrange anything in a square formation, we are essentially arranging them equally in rows and columns. Therefore, by taking the square root of the total number of students, which is 169, this will tell us the number of students that should be arranged in each row and the number of rows required.
A square root of a number is that value which, when multiplied by itself, gives the original number. The square root of 169 is 13. So, for a square formation, there should be 13 students in each row.

Answer:
πr²
Step-by-step explanation:
The surface area of a circle is πr²
Pie is 22/7 or 3.14
While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.
To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.
If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.
22/7 X 7 ²
22/7 X 7 X 7
22 X 7
154cm²

Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
Answer:
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
3r+(-21)=8+(-8r)+4
-21+8+4=3r+(-8r)
-9=-5r
