The conversion of 230.2 g to metric ton is given by 0.0002302 metric tons.

Grams (g) and metric ton (MT) are the SI units of mass. Scientist measure various things with different units. The following are measures and their units;

Convert metric ton to grams:

1 metric ton = 1,000,000 grams

230.2 g = 230.2 ÷ 1,000,000

= 0.0002302 metric tons

Therefore, it can be said that 230.2 g is equivalent to 0.0002302 metric tons

As per the given angle of elevation, the height of the building is 368.5 ft.

Angle of elevation:

Basically, an angle between the horizontal plane and line of sight from the observer's eye to some object above is known as angle of elevation.

Given,

The angle of elevation to the top of a Building in New York is found to be 2 degrees from the ground at a distance of 2 miles from the base of the building.

Here we need to find the height of the building and round to the tenths.

Here we know that the angle of elevation of the building in New York is written as,

=> θ = 2°

And the distance of observation point from the building is given as,

=> l = 2 miles

Here we know that, 1 miles = 5280 feet

So, the value of l in feet is,

=> l = 2 x 5280

=> l = 10560

Now, it is required to calculate the height of the building. Use the concept of trigonometry to find the height,

So, the height is calculated as,

=> tan θ =h/l

Apply the values on the formula, then we get,

=> tan 2° = h/10560

=> 0.0349 = h/10560

=> h = 0.0349 x 10560

=> h = 368.5 feet.

Therefore, the height of the building is 368.5 ft.

Answer: 32 km

Step-by-step explanation:

Set the unknown value as x and use proportions to find the answer:

[tex]\frac{72}{90} =\frac{x}{40} \\\\90x=72*40\\\\x=\frac{72*40}{90} =32[/tex]

The linear equation that represents the number of words Nebi types per minutes after the timer is started is: w = 50m + 250.

Linear equation can be written in the slope-intercept form as y = kx + b. To write this, find the values of the slope = m, and the y-intercept of starting value = b.

From the equation given, find the unit rate/slope, which is the number of words typed in one minute.

Thus, we have:

Slope/unit rate (m) = 150/3

m = 50 words per minute.

The y-intercept (b) is 250, because it is the initial/starting value.

Let w represent the total number of words, and m represents the minutes after the starting time.

To write the linear equation, substitute k = 50 and b = 250 into w = km + b:

w = 50m + 250

The measure of the missing length of the triangle is 16 units.

According to the question,

We have the following information:

We have a figure of right-angled triangle where two sides are given.

In order to find the third side of this triangle, we will use the Pythagoras theorem.

So, we have the following expression:

[tex]AC^{2} = AB^{2} + BC^{2}[/tex]

[tex](20)^{2} = AB^{2} + (12)^{2}[/tex]

The value of 198.02 percent of £83.02 is £164.40

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

The value will be illustrated thus:

198.02% × £83.02

= 1.9802 × £83.02

= £164.3962

The probability that Jordan will win in three or fewer matches if they play 5 matches using binomial probability distribution is; 0.95636

The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability.

The general formula for binomial probability distribution is;

P(X = x) = nCx * p^(x) * (1 - p)^(n - x)

where;

Px = the probability of exactly x events occurring

x = the number of expected successful outcomes

n = the number of trials you perform

nCx = the number of different combinations for x items you test in n trials

We are given probability that Jordan wins the match as 1/3. Thus;

p = 1/3 = 0.333

Thus, probability that Jordan will win in three or fewer matches if they play 5 matches is;

P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)

As per the concept of unitary method, there are 180.8 ml of the 65% mixture will you need to add to obtain the desired solution

Unitary method:

Basically, the way of finding out the solution of a problem by initially finding out the value of a single unit, and then finding out the essential value by multiplying the single unit value.

Given,

You need a 35% alcohol solution. On hand, you have a 300 mL of a 20% alcohol mixture. You also have 65% alcohol mixture.

Here we need to find how much of the 65% mixture will you need to add to obtain the desired solution.

Let us consider x be the amount of the 65%  alcohol needed (in milliliters.

Here the amount of the resulting 65%  alcohol solution will be is (x+15) milliliters.

So, the amount of the "pure" alcohol in 300 mL of the 20% alcohol solution is written as,

=> 0.20 x 300 mL.

And the amount of the "pure" alcohol in x mL of the 65% alcohol solution is written as,

=> 0.65 * x mL.

Therefore, the total amount of the "pure" alcohol in ingredients is the sum  and it can be calculated as,

=> 0.20*300 + 0.65*x mL.

So, it should be equal to the amount of the "pure" alcohol in the mixture, which is written as,

=> 0.35 * (x+15) ml.

Therefore, your "pure alcohol" equation is

=> 0.65* x + 0.20 * 300 = 0.35*(x+15).

When we simplify this one then we get the value of x as,

=> 0.65* x + 0.20 * 300 = 0.35*(x+15).

=> 0.65x + 60 = 0.35x + 5.25

=> 0.3x + 54.25

=> x = 180.8
