Which of the following is equivalent to the expression below?(3) (4) (-3/4)

A. -12(-3/4)
B. -13(3/4)
C. -12- 3/4
D. -12 + 3/4

Answers

The expression (3)(4)(-3/4) is equivalent to -9.

None of the given options is correct.

Given information:

The expression is (3) (4) (-3/4).

Multiplying 3, 4, and -3/4, we get:

(3)(4)(-3/4),

Simplify the parenthesis,

= 12(-3/4)

Multiplying,

= -36/4

Divide -36 by 4, and we get,

= -9

Therefore, the expression is equivalent to:-9

IS 25%, YOU FIND OUT BY DIVIDING 8760/100=87.60 WHICH REPRESENTS 1 PERCENT AND THEN 2160/87.60=25%
ALSO, IF YOU DIVIDE 8760/2190=4, SO THIS REPRESENTS 25%

In a video game, two golfers tee off at hole 6, which has the coordinates (–32, –27). Golfer A’s ball lands at (–43, –18). Golfer B’s ball lands at (–44, –16). Which golfer hit the longer shot?

Answers

Answer:

Golfer B's hit the longer shot.

Step-by-step explanation:

In a video game, two golfers tee off at hole 6

Position of hole at (-32,-27)

Golfer A's ball lands at (-43,-18)

Golfer B's balls lands at (-44,-16)

Distance formula:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

Distance of shot of Golfer A's $=√((-32+43)^2+(-27+18)^2)=√(11^2+9^2)\approx 14.21$

Distance of shot of Golfer B's $=√((-32+44)^2+(-27+16)^2)=√(12^2+11^2)\approx 16.28$

16.28 > 14.21

Golfer B's shot > Golfer A's shot

Hence, Golfer B's hit the longer shot.

Using Pythagoras' theorem, you can work out the distance the balls travelled.
Golfer A: -43 - -32 = -43 + 32 = -11
-27 - -16 = -27 + 16 = -11
a² + b² = c²
(-11)² + (-11)² = √242 = 15.556

Golfer B: -44 - -32 = -44 + 32 = -12
-27 - -16 = -27 + 16 = -11
a² + b² = c²
(-11)² + (-12)² = √265 = 16.278

∴ B hit the longest shot.
