OK soto find percentages or portions of a number you need to do this equation %/100 * x/#. Meaning that for example number one it would be 23/100 * x/52. And the process is to multiply the numbers opposite of each other and divide by 100. Which would give you 11.96. For instances like number two you would have to put the numbers depending on what they are for example 12/42 * x/100
Tell me if any of this makes sense and I can give you more explanation if you need help

Sock hop (ExH). You have 10 pairs of socks, fi ve black and fi ve blue, but they are not paired up. Instead, they are all mixed
kvasek [131]

Answer:

Step-by-step explanation:

Total number of pairs of socks in a drawer = 10

Number of black pairs of socks = 5

Number of blue pairs of socks  = 5

A. If you picked 2 socks [black] and [blue] 3rd pick guarantees you will have one pair of either blue or black

Number of socks you pull out to guarantee that you have a pair of one color = 3 socks

B. If you want to pick 2 good pairs and your 6 picks are worst case, so 7th pick of the socks will give you good pair of two colors.

Number of socks you pull out to have two good pairs = 7 socks

C. If you want to have a pair of black socks your worst case will be you pick all 10 blue socks so another 2 socks must be black.

Number of socks you pull out to have two black socks = 12 socks

4 consecutive numbers that add up to 8
Digiron [165]

Answer:

The answer top your question is: 1/2, 3/2, 5/2 and 7/2

Step-by-step explanation:

Data

4 consecutive numbers that add up to 8

First number = n

2nd number = n + 1

3rd number = n + 2

4th number = n + 3

Now, add them up           n + n + 1 + n + 2 + n + 3 = 8        

                                                                                          Simplify like terms

                                         4n + 6 = 8

                                         4n = 8 - 6

                                         4n = 2

                                         n = 2/4 = 1/2

First number = n         = 1/2

2nd number = n + 1    = 1/2 + 1 = 3/2

3rd number = n + 2    = 1/2 + 2 = 5/2

4th number = n + 3    = 1/2 + 3 = 7/2

A rectangular tank 60 cm long and 50 cm wide is /5 full of water. When 24 liters of water are added, the water level rises to th
bija089 [108]

Answer:

The tank is 10cm high

Step-by-step explanation:

Given

L=60cm -- length

W=60cm -- width

x = \frac{1}{5} --- water lever

Addition = 24L

Required

The height of the tank

Let y represents the remaining fraction before water is added.

So:

y + x = 1

Make y the subject

y = 1 - x

y = 1 - \frac{1}{5}

Solve

y = \frac{5 - 1}{5}

y = \frac{4}{5}

Represent the volume of the tank with v

So:

y * v = 24L

Make v the subject

v = \frac{24L}{y}

Substitute: y = \frac{4}{5}

v = \frac{24L}{4/5}

v = 30L

Represent the height of the tank with h;

So, the volume of the tank is:

v = lwh

Make h the subject

h = \frac{v}{lw}

Substitute values for v, l and w

h = \frac{30L}{60cm * 50cm}

Convert 30L to cm^3

h = \frac{30*1000cm^3}{60cm * 50cm}

h = \frac{30000cm^3}{3000cm^2}

h = 10cm
