Answer:

1/2

Step-by-step explanation:

(1/8+3/12)×(11/6-1/2)

Using bodmas

Deal with the bracket first and it should start with the addition

1/8+3/12

Lcm of the two is 96

12+24/96

=36/96

Then move to the next bracket

11/6-1/2

Lcm is 6

11-3/6

=8/6

Bring the two answers together

36/96×8/6

=1/2

Answer:

1/2

Step-by-step explanation:

1/8 + 3/12 is 3/8.

1 1/6 - 1/2 is 1 1/3.

If you multiply 3/8 and 1 1/3, you'll get 1/2

Answer:

675 litres
80 mL

Step-by-step explanation:

1. The total amount of oil in the two tanks at the start is ...

total oil = n + (n +150) + 0 = 2n+150 . . . . litres

The amount of oil in tank C at the end is 1/3 this amount, or

oil in tank C = (total oil)/3 = (2n+150)/3 . . . . litres

The amount pumped into tank C was 500 litres, so we have ...

(2n +150)/3 = 500

2n +150 = 1500 . . . . . . multiply by 3

2n = 1350 . . . . . . . . . . . subtract 150

1350/2 = n = 675 . . . . . divide by the coefficient of n

___

2. Let x represent the amount remaining in container A. Then 4x is the amount in tank B. Before the transfer, the amount in each container was the same, so ...

x +120 = 4x -120 . . . . . A had 120 more than remains; B had 120 less

240 = 3x . . . . . . . . add 120-x

240/3 = x = 80 . . . divide by the coefficient of x

The amount of liquid left in container A is 80 mL.

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.

kari74 [83]

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

Step-by-step explanation:

Given

L(3,4)

M(1,-2)

Determining the length of LM

(x₁, y₁) = (3, 4)

(x₂, y₂) = (1, -2)

The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

$=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}$

$=\sqrt{2^2+6^2}$

$=\sqrt{4+36}$

$=\sqrt{40}$

$=\sqrt{4\times 10}$

$=\sqrt{2^2\times \:10}$

$=2\sqrt{10}$

$=6.3$

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

If an arithmetic sequence

goblinko [34]

Answer:

a₄ = 12

Step-by-step explanation:

To obtain the terms in the sequence add 2 to the previous term, that is

a₂ = a₁ + 2 = 6 + 2 = 8

a₃ = a₂ + 2 = 8 + 2 = 10

a₄ = a₃ + 2 = 10 + 2 = 12
