Answer:

720000 J

Step-by-step explanation:

The formula is

Work = Force * Distance

Here we have the weight force, which is calculated as w = m * g

acceleration of gravity (g) ≈ 10 m/s

people's mass (m) = 12 * 50 kg = 600 kg

So Force = 10 m/s * 600 kg = 6000 N

Distance = 120 m

Work = Force * Distance = 6000 N * 120 m = 720000 J = 720 kJ

  5 5/6 hours

Step-by-step explanation:

We can add the times, but it is more convenient to use multiplication.

  5(3/6) + 4(5/6) = (15/6) +(20/6) = 35/6 = 5 5/6

Step-by-step explanation:

Answer:

x = - 3, y = - 11

Step-by-step explanation:

Given the 2 equations

y = 7x + 10 → (1)

y = - 4x - 23 → (2)

Substitute y = 7x + 10 into (2)

7x + 10 = - 4x - 23 ( add 4x to both sides )

11x + 10 = - 23 ( subtract 10 from both sides )

11x = - 33 ( divide both sides by 11 )

x = - 3

Substitute x = - 3 into either of the 2 equations and evaluate for y

Substituting into (1)

y = 7(- 3) + 10 = - 21 + 10 = - 11

Answer:

[tex]y = 4(2^{x} )[/tex]

Step-by-step explanation:

The general form for an exponential function is [tex]y = kb^{x}[/tex]

When x = 2,  y = 16    So, [tex]16 = kb^{2}[/tex]    

and when x = 3,  y = 32    So, [tex]32 = kb^{3}[/tex]

Divide  [tex]\frac{32}{16} = \frac{kb^{3} }{kb^{2} }[/tex]

2 = b

Now, [tex]16 = k2^{2}[/tex]

16 = 4k

k = 4

Therefore, the exponential function is [tex]y = 4(2^{x} )[/tex]

Answer:

Answer:

3a) 4:5

4a) 1:4

Step-by-step explanation:

3a) you just find the GFC of both 12 and 15, and then use the first number for girls and 2nd for boys, in this case 4 for girls and 5 for boys giving you 4:5.

4a) You just add 4 to 12 it gives you 16 and divide 4 and 16 by 4 giving you a ratio of 1:4.

Step-by-step explanation:

y-13<6

y<6+13

y<19

hope it helps.

Answer:

y<19

Step-by-step explanation:

Add 13 to both sides.

y<6+13

Simplify  6+13  to  19.

y<19

Answer:

Ratio 5 = 9375

Ratio 3 = 5625

Step-by-step explanation:

Write your question here (Keep it simple and clear to get the best answer)

a sum of 1,5000.00 in the ratio 5:3

The ratio is given as:

5:3

Total Proportion = 5+3 = 8

For ratio 5

= 5/8 × 15000

= 9375

For ratio 3

= 3/8 × 15000

= 5625

He makes £470 profit

Step-by-step explanation:

He pays $160 for 60 jumpers.

He sells 80% (48) for $12 each. Income of $576

He puts the remaining (12) on sale for one full one half off.

He sells 3 for half price ($6) and 3 for full price ($12) Income of $54

$576 + $54 = $630

Answer: 8 days

Step-by-step explanation:  Get out your calculator. Put in 1/2, did you get .5? You should've gotten .5. Now if you put in 4 / .5, then you'll get 8. Seems pretty simple I guess. Lmk if this helped you.

The dog food last for 8 days.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Mr. Simpson feeds his dog 1⁄2 of a cup of dog food each day.

Total cups of food= 4

So, 4 cups of dog food lasts

= 4/ (1/2)

= 4 x2

= 8

Hence, the dog food last for 8 days.

Answer:

160

Step-by-step explanation:

Answer:

15 percent

Step-by-step explanation:

First use the equation part over total to get 27/180. Then reduce the equation by dividing both the numerator 27 and the denominator 180 by 9. You are left with 3/20. Then use your calculator or you can work it out long hand to get 0.15. You times 0.15 by 100 if you want to find the percent, leaving you with 15 percent.
