Answer:

[tex]-27x^2\\[/tex]

Step-by-step explanation:

(Assuming you can use a calculator)

[tex]\sqrt[3]{-729x^6} = \sqrt[3]{-1} * \sqrt[3]{729} * \sqrt[3]{x^6} \\\sqrt[3]{-1} =-1\\\sqrt[3]{729} = 27\\\sqrt[3]{x^6} = ((x^6)^{1/3}) = x^(6/3) = x^2\\\\hence\\\sqrt[3]{-729x^6} = -1*27*x^2 = -27x^2[/tex]

Answer:

£43.05 (I believe, refer to step-by-step explanation.)

Step-by-step explanation:

Let's compare both of these tubs if we were to buy either of them for 14 days.

Starting with the 1 kilogram tub we need to do the calculation:

£3.20 × 14 = £44.80

(Type 3.2×14 into your calculator or write on paper this way to calculate.)

Now let's do the 2 kilogram tub.

£6.15 × 7 = £43.05

(Type 6.15×7 into your calculator or write on paper this way to calculate.)

The reason why I have put 7 instead of 14 is because it is 2 kilograms. Since Pippa uses 1 kilogram per day, you only need to buy 7. 2 × 7 = 14

So comparing either of these prices, buying 7 2-kilogram tubs is much cheaper compared to the 14 1-kilogram tubs.

Answer:

[tex]P(E) = 26 \%[/tex]

Step-by-step explanation:

Given

[tex]P(F) = 46\%[/tex]

[tex]P(E\ and\ F) = 10\%[/tex]

[tex]P(E\ or\ F) = 62\%[/tex]

Required

Find P(E)

In probability:

[tex]P(E\ and\ F) = P(E) + P(F) - p(E\ or\ F)[/tex]

Substitute the right values

[tex]10\% = P(E) + 46\% - 62\%[/tex]

[tex]10\% = P(E) -16 \%[/tex]

Collect Like Terms

[tex]P(E) = 10\% +16 \%[/tex]

[tex]P(E) = 26 \%[/tex]

It is a probability because all probabilities are within the range 0 to 100%

Answer:

31,000 and 6

Step-by-step explanation:

The product of 0.031 and 1,000,000 is 31,000, because the decimal point in 0.031 moves  6 places to the right.

Answer:

questions mistake look questions and apply the formula 1/2 B×H

if you have a triangle and don't know where are the base and the high use this formula

area = 0.5 × side  × side  × sin the angle between the 2 sides

area = o.5 (32.4) (49.2) (sin 18.5)

         = 797.04 × sin 18.5

          =252.9

Answer:

x = 13

Step-by-step explanation:

1. We can tell if the radical is in its simplest form if the square root term is a number that cannot be broken down to give a perfect square factor

what we are saying in this case is that if the number that is under the square root sign is one in which cannot be broken down to give a perfect square or that a perfect square is not its factor. Then it is in the simplest form

2. 512 = 2^(x-4)

512 = 2^9

2^9 = 2^(x-4)

since base is equal, we equate the powers

9 = x - 4

x = 9 + 4

x = 13

Answer:

the length of the other altitude of the given parallelogram will be 6 units and option B is the correct choice.

The length of the other altitude in the parallelogram will be B. 6 units.

The equation to find the altitude in the parallelogram will be:

Altitude 1 × Vertical base = Altitude 2 × Horizontal base

✓22.5 × ✓40 = Altitude 2 × 5

30 = Altitude 2 × 5

Altitude 2 = 30/5

Altitude = 6
