The lost pair of weight can be found by subtracting the a known pair from

the total weight leaving the value of the lost pair.

The lost weight of a pair of boys is 120 kg

Reasons:

Let a, b, c, and d represent the weights of the four boys, we have;

The number of ways of selecting pairs (two boys) of boys from a group of

four is given using combination formula as follows;

[tex]_nC_r = \dfrac{n!}{r! \cdot (n - r)!}[/tex]

Which gives;

[tex]_4C_2 = \dfrac{4!}{2! \cdot (4 - 2)!} = 6[/tex]

₄C₂ = 6

Therefore, the weights of the pairs are;

a + b = 110

a + c = 112

a + d = 113

b + c = 118

b + d = 121

c + d = Lost weight

a + b + c + d = 230 (given)

Therefore;

The lost weight, c + d = 230 - (a + b)

Which gives;

c + d = 230 - (110) = 120

The lost weight = c + d = 120

Answer:

116

Step-by-step explanation:

you can use variables

a+b=110

a+c=112

a+d=113

b+c=118

b+d=121

add up the weights and you get 574 kg (you need to find c+d)

3a+3b+2c+2d=574

a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3

you are left with c+d=116

similar method to the answer previously

Answer:

To solve for h, isolate the “h” on one side of the equation.

Combine like terms on the left sides (h). When combing like terms add and subtract as normal and attach the variable.

4-14h=60

Subtract 4 from both sides.

-14h=56

Divide both sides by -14.

h=-4

Hope this helps! :)

Answer:

h = -4.

Step-by-step explanation:

4-6h-8h=60

4-4-6h-8h = 60-4

-14h = 56

h = 56/-14

= -4.

Step-by-step explanation:

Answer:

Step-by-step explanation:

the x intercept occurs when y=0

[tex]0=\frac{2x+6}{x-1}\\0=2x+6\\x=-3\\(-3,0)[/tex]

The y intercept occurs when x=0

[tex]y=\frac{2(0)+6}{0-1}=-6\\(0,-6)[/tex]

Answer:

Below in bold.

Step-by-step explanation:

To find the x -intercept put f(x) = 0:

(2x - 6)/(x - 1) = 0

2x - 6 = 0

2x = 6

x = 3

So the x-intercept is at the point(3, 0).

To find the y-intercept put x = 0:

y = (2(0) - 6)/(0 - 1)

= -6/-1

= 6

So the x-intercept is at the point(0, 6).

C = 12 * pi

C = 2*pi * r

Solution

2*pi * r = 12*pi                        Divide both sides by 2pi

2*pi * r/ 2*pi = 12*pi/2pi

r = 6

Answer: the diameter = 2 * r

the diameter = 12

Answer:

Step-by-step explanation:

Step-by-step explanation:

4z = 8

z = 8/4

z = 2

3x - 2z = 11

3x - 2.2 = 11

3x - 4 = 11

3x = 11 + 4

3x = 15

x = 15/3

x = 5

x - 4y + z = 11

5 - 4y + 2 = 11

-4y = 11 - 5 - 2

-4y = 4

y = 4/-4

y = -1

Solution → {x,y,z} = {5,-1,2}

Answer:

20 out of 120 times

Step-by-step explanation:

As others have said, the general formula is:

expected successes = probability*number of trials

Perhaps an easier question: If you roll a die 6 times, how many 4s would you expect to get?

1, right? 1 out of every 6. That’s what 1/6 means.

If you roll a die 12 times, you expect 2. 2/12 = 1/6

Answer: 7.2

Step-by-step explanation: u times 0.9 by 15, then separately u times 2.1 by 3. then u take both numbers and subtract.

Answer:

Step-by-step explanation:

0.9d - 2.1f = 0.9*15 - 2.1*3

                 = 13.5 - 6.3

                 = 7.2

Answer:

B) <

Step-by-step explanation:

Since both numbers are being multiplied by 10^-5, we can completely cut that part out of the inequality and instead just compare the values 3.2 and 4.6. It is obvious when looking at the problem that 3.2 is smaller than 4.6, so we will use the less than symbol <.

Hopefully that's helpful! Good luck on your quiz. :)

Answer:

296 miles

Step-by-step explanation:

Use a proportion:

111/( 3/8) = x/ 1

Cross Multiply

   (3/8)x = 111

Multiply both sides by 8/3 ; reciprocal

          x = (8/3) (111)

          x = 296 miles

(Hope this helps can I pls have brainlist (crown)☺️)

Step-by-step explanation:

Example:

Discount formula:

(original_price * discount / 100)

_____________________________________________________

Percentage discount is a discount that is given to a product or service that is given as an amount per hundred. For example, a percentage discount of 20% would mean that an item that originally cost $100 would now cost $80. This is common with promotional and seasonal sales, as a way of encouraging consumers to buy an item at a reduced cost.

___________________________________________________

$279 - $55.80 = $223.20

You would therefore be saving $55.80 on the purchase for a final price of $223.20.

For this calculator, a "stackable additional discount" means getting a further percent off of a product after a discount is applied. Using the same example, assume that the 20% discount is a discount applied by the store to the product. If you have a coupon for another 15% off, the 15% off would then be applied to the discounted price of $223.20. It is not a total of 35% off of the original price. It is less:

15% of $223.20 = $33.48

$223.20 - $33.48 = $189.72

Thus, with a 20% discount off of $279, and an additional 15% off of that discounted price, you would end up saving a total of:

$55.80 + $33.48 = $89.28

This equates to a 32% discount, rather than a 35% discount, and this calculation is how the calculator is intended to be used. As an example, to more efficiently compute the discount described above:

Final price = (0.80 × 279) × 0.85 = $189.72

This is because 80% of the original price is the same as subtracting 20% of the original price from the original price. The same is true for 85% and 15% case applied to the discounted price.

Answer:

40%

Step-by-step explanation:

6 divided by 15 times 100 = 40

Answer:

40

(40%)

Step-by-step explanation:

6 / 15 = 0.4

0.4 * 100 = 40%

We can check this by doing 40% times 15;

15 * 0.4 = 6 ✓

It checks :D
