1 5/6 times 4/7 so whats the answer

The value of m from the given equation is 3

Given the expression

5m + 4 = 19

Subtract 4 from both sides using the subtraction law of equality.

5m + 4 - 4 = 19 - 4

5m = 19 - 4

5m = 15

Divide both sides by 5 using the Division law of equality

5m/5 = 15/5

m = 3

Hence the value of m from the given equation is 3

Using the arrangements formula and the probability concept, it is found that:

The number of possible arrangements of n elements is given by:

[tex]A_n = n![/tex]

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 4 runners, hence, the number of different ways the race can be completed is:

[tex]A_4 = 4! = 24[/tex]

Considering A first and C second, for the third and fourth positions, it is an arrangement of 2 elements, hence:

[tex]A_2 = 2! = 2[/tex]

The probability is:

[tex]p = \frac{2}{24} = \frac{1}{12}[/tex]

[tex]\frac{1}{12}[/tex] probability that A finishes first and C finishes second.

Answer: To combine like terms, we must first understand what they are. Like terms are, well like. An example will make more sense. See the equation 2 + 4x - 5y * 0.2xy. Here, we have no like terms. Why? Because 2 has no variable while 4x has x. However, 4x and 5y don't have the same variable so they are NOT like either. Do not fall into the 0.2xy trap either because that is not like with 4x or 5y. Now that you (hopefully) understand let us try an example.

5x * 2x - 24 = 16

As you can see, the like terms here are 5x and 2x as well as 4 and 16. Now let us simplify by bringing the like terms together.

5x * 2x = 16 + 24

10x^2 = 40 (Be careful here! since we are multiplying x twice it will become x^2)

x^2 = 40/10

x^2 = 4

x = 2 (or -2)

And there you go! You just simplified using like terms.

The explicit formula for calculating the sum is

The sum of the nth term of a sequence is expressed as;

a is the first term

d is the common difference

6 gallons

If you have 4 gallons for 30 plants, half of 4 gallons is 2, which will water 15 plants. Add 4 gallons plus 2 gallons, it gives you 6 gallons and 45 plants.

It use 6 gallons of water to water 45 plants.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

WE have been given that;

Let 4 gallons of water ... 30 plants

Let x gallons of water = ? ... 45 plants

The water will it take to water 45 plants, it can be calculate this using the following steps;

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Therefore, We will use 6 gallons of water to water 45 plants.

At the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below -

P(h) = P[tex]e^{-0.000122h}[/tex]

where {P} is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters.

For 50% of the air pressure at the surface of the Earth, we can write -

50P/100 = P[tex]e^{-0.000122h}[/tex]

1P/2 = P[tex]e^{-0.000122h}[/tex]

1/2 =  [tex]e^{-0.000122h}[/tex]

- 0.000122h = log(1/2) = - 0.301

h = - 0.301/- 0.000122

h = 2467.2 meters

Therefore, at the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

Answer:

Step-by-step explanation:

Let x and y represent the prices of adult and student tickets, respectively. Then the revenue equations are ...

  13x +9y = 138

  3x +14y = 163

Solving this using a graphing calculator, we find (x, y) = (3, 11).

The price of an adult ticket is $3; the price of a student ticket is $11.

_____

Algebraic solution

When the numbers are "messy," as they are here, I like to use the "cross-multiplication method" for solution. I find it easier to use the order 1, x, y, rather than the order x, y, 1 as shown in the second attachment. That way, the coefficients are in their original order, with the first coefficient repeated. Note the right-side constant must be subtracted to get the form ax+by+c = 0.

  [tex]\begin{array}{cccc}13&9&-138&13\\3&14&-163&3\end{array}[/tex]

Then we have ...

  1/(13·14 -3·9) = x/(9·(-163) -14·(-138)) = y/((-138)·3 -(-163)·13)

  x = 465/155 = 3 . . . . price of an adult ticket

  y = 1705/155 = 11 . . . price of a student ticket

The acres of land she will need to produce 24 tons of nuts is 28 acres.

9 tons of nuts needs 10 1 / 2(21 / 2) acres of land

24 tons of nuts will need ? acres of land

cross multiply

Acres of land needed = 24 × 21 / 2 / 9

Acres of land needed = 252 / 9

Using the binomial distribution, it is found that there is a 0.81 = 81% probability that NEITHER customer is selected to receive a coupon.

For each customer, there are only two possible outcomes, either they receive the coupon, or they do not. The probability of a customer receiving the coupon is independent of any other customer, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that neither receives a coupon is P(X = 0), thus:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{2,0}.(0.1)^{0}.(0.9)^{2} = 0.81[/tex]

0.81 = 81% probability that NEITHER customer is selected to receive a coupon.
