Answer:

17 1/8 km

Step-by-step explanation:

6 7/8 + 5 1/2 + 4 3/4

The common denominator is 8

6 7/8 already has a denominator of 8

5 1/2 = 5 1/2*4/4 = 5 4/8

4 3/4 *2/2 = 4 6/8

6 7/8 + 5 4/8 + 4 6/8

15 17/8

15 + 8/8+ 8/8+1/8

15 + 1 + 1 + 1/8

17 1/8

Answer:

17⅛ km

Step-by-step explanation:

Total distance covered = sum of the two individual distances

= 6⅞ + 5½ + 4¾

= (6 + 5 + 4) + (⅞ + ½ + ¾)

= 15 + [7 + 1(4) + 3(2)]/8

(LCM of 8,2 and 4 is 8)

= 15 + (17/8)

= 15 + 2⅛

= 17⅛

If u = -8i + 7j, what is the magnitude of -5u? Simplify any radicals.

lubasha [3.4K]

Answer:

$- 5 \sqrt{113}$

Step-by-step explanation:

Find the magnitude of the complex number

Notice the magnitude is equal to

$u = \sqrt{ {a}^{2} + {b}^{2} }$

where a is the real number and b is the imaginary number.

Substitute

$u = \sqrt{ - 8 {}^{2} + 7 {}^{2} }$

$u = \sqrt{64 + 49}$

$u = \sqrt{113}$

Multiply this by -5

$- 5 \sqrt{113}$

A rectangular scoreboard at a football filed has an area of 56 square yards.the scoreboard has a height of 4 yeatds. What is the

monitta

Alright so it's a rectangle so we know that both lengths are equal to each other and both widths are equal to each other. We know that the area, which is length times width, equals 56 and we also know that the height is 4 yards. So what times 4 equals 56? Calculate 56/4 and you will get 14. The height is 4 yards and the length is 14 yards. You're not done yet though! The question is looking for the perimeter, which is the total of all four sides. Since both lengths and both widths are equal, you would need to do 14+14+4+4. This equals 36 yards. Therefore the perimeter is 36 yards.
