Select the correct answer. Victor and Dennis are weeding a garden. If Victor worked alone, it would take him 30 minutes. Working together, they would finish in 12 minutes. When x represents the number of minutes it would take Dennis working alone, this situation is represented by this equation: Working alone, how long would it take Dennis to weed the garden? A. 15 minutes B. 18 minutes C. 20 minutes D. The rational equation has no valid solutions.

Answers

Answer:

C. 20 minutes

Step-by-step explanation:

If Victor (V) worked alone, it would take him 30 minutes.

30 * V = 1

V = 1 / 30

When x represents the number of minutes it would take Dennis (D) working alone,

x * D = 1

D = 1 / x

Working together, they would finish in 12 minutes

12 (V + D) = 1

12( 1/30  + 1/x) =1

1/30 + 1/x = 1/12

Multiply all through by x

x/30 + 1 = x/12

x/30 - x/12 = - 1

( 2x - 5x ) / 60 = - 1

- 3x / 60 = - 1

- 3x = -60

x = -60 / -3 = 20 minutes

- Mia and Lily are trying to find the nearest whole number to the square root of 120

Mia: It is 10
Lily: It is 11

Who is correct?

Give a reason for your answer.​

Answers

Lily is correct

11x11=121 and 10x10 is 110 so the nearest number of the square root 120 is 11.

For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Given that,

Mia has 10 number.And,  Lily is 11 number.

Now if we square both the numbers so it comes:

10^2 = 10011^2  = 121

So, 121 is nearest to 120.

Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

800+900×25-65(89+5)-12÷67-7​

Answers

Answer:

As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,

'800+900×25-65(89-5)-12÷67-7'

Solving the bracket gives us:

'800+900×25-65(84)-12÷67-7'

Now avoiding the Bracket:

'800+900×25-5460-12÷67-7'

Now first we have to do MUltiplication, so we will get,

'800+22500-5460-12÷67-7'

Now let's do the division, so we will get,

'800+22500-5460-0.17-7'

Now lets do the additions and subtractions we will get,

Use the multiplier method to increase £258 by 43%
You must show your working out.

Answers

Answer:

£368.94

Step-by-step explanation:

The multiplier for 43% is 0.43

0.43 x 258 = 110.94 which is 43%

But if you are increasing 258 by 43% you must add on 258 as well

Or instead you can just do 258 x 1.43= 368.94

Find the midpoint of the line segment with end coordinates of:(−1,−6) and (4,5)
Give coordinates as decimals where appropriate.

Answers

The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

Finding the midpoint of the line segment

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:

((x1 + x2)/2, (y1 + y2)/2)

In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:

((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)

Simplifying this expression, we get:

((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)

Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).
