Answer:

${8}^{ \frac{3}{4} } • {3}^{ \frac{15}{4} }$ (third opti0n)

Step-by-step explanation:

$(8 • {3}^{5} {)}^{ \frac{3}{4} }$

${8}^{ \frac{3}{4} } • ( {3}^{5} {)}^{ \frac{3}{4} }$

$= {8}^{ \frac{3}{4} } • {3}^{ \frac{15}{4} }$

On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball traveled 79 met

Sav [38]

Answer:

0.395 kilometre

Step-by-step explanation:

Given:

On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole.

On his second stroke, the ball traveled 79 meters and went into the hole.

Question asked:

How many kilometres from the hole was Martin when he started?

Solution:

Let distance from Martin starting point to the hole in meters = $x$

On Martin's first stroke, ball traveled = $\frac{4}{5} \ of \ total \ distance\ to\ the\ hole$

$=\frac{4}{5} \times x=\frac{4x}{5}$

On his second stroke, the ball traveled and went to the hole = 79 meters

Total distance from starting point to the hole = Ball traveled from first stroke + Ball traveled from second stroke

$x=\frac{4x}{5} +79\\ \\ Subtracting\ both\ sides\ by \ \frac{4x}{5}\\ \\ x- \frac{4x}{5}= \frac{4x}{5}- \frac{4x}{5}+79\\ \\ \frac{5x-4x}{5} =79\\ \\ By \ cross\ multiplication\\ \\ x=79\times5\\ \\ x=395\ meters$

Now, convert it into kilometre:

1000 meter = 1 km

1 meter = $\frac{1}{1000}$

395 meters = $\frac{1}{1000}\times395=0.395\ kilometre$

Thus, there are 0.395 kilometre distance from Martin starting point to the hole.

Simplify the expression -3 ÷ (-2/5

Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first from left to right)

Addition>Subtraction (See Multiplication>Division)

So First, lets solve the Parenthesis. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just Divide.

-3/-.4=7.5

The solution is 7.5

Hope this helps!

Im Gonna Do 14 And 15.

14:
3/4 (9/12) + 1/3 (4/12) = 13/12
4/5 (16/20) - 1/4 (5/20) = 11/20

15:
-15 < -6
-31 < -19
-5 < 20
-21 < -15
0 < 22
-57 < -26
-71 < -10
3 < 21
-124 < 30
-43 < 18

Hope This Helps!
