At the present time, Daniel is 8 years older than his cousin William. In two years' time, Daniel will be 3 times older than William is at the present time. How old is Daniel at the present time?

Answers

Answer:

Daniel is 10 years old presently

Step-by-step explanation:

Since we do not know the ages of both people, we assign variables.

Let Daniel’s present age be d while Willam’s present age is w

Daniel is 8 years older;

Mathematically;

d = w + 8 •••••••••••(i)

In two years time Daniel’s age will be d + 2 while William’s age will be w + 2

We know that Daniel will be 3 times as old as Williams will be in these two years time

Mathematically;

d + 2 = 3(w + 2) ••••••• (ii)

From equation 1, we have w = d-8

we substitute this into equation ii

d + 2 = 3(d-8+2)

d + 2 = 3(d-6)

d + 2 = 3d - 18

3d - d = 18 + 2

2d = 20

d = 20/2

d = 10 years

If a sample of 2.00 moles of NO gas was reacted with excess
oxygen, how many moles of nitrogen dioxide gas would be
produced?

Answers

Answer:

2 moles

Step-by-step explanation:

first you have to balance the equation:

2NO + O2⇒2NO2

then set up your mole to mole ratio

2 mol NO2/2 mol NO

multiply by the given 2.00 mol NO gas

and you should get 2 mol NO2

Final answer:

Starting with 2.00 moles of nitrogen monoxide (NO) and reacting it with excess oxygen (O2) will produce 2.00 moles of nitrogen dioxide (NO2) based on the 1:1 mole ratio from the balanced chemical equation.

Explanation:

The student is asking about the stoichiometry of a chemical reaction involving nitrogen monoxide (NO) and oxygen (O2) to produce nitrogen dioxide (NO2). In the balanced chemical equation, the reaction is typically represented as 2NO + O2
ightarrow 2NO2. Following the mole ratio from the balanced equation, 1 mole of NO reacts with 1/2 mole of O2 to produce 1 mole of NO2. Consequently, if you start with 2.00 moles of NO, you would also produce 2.00 moles of NO2 given that oxygen is in excess and will not limit the reaction.

This is because the balanced chemical equation shows the NO and NO2 in a 1:1 mole ratio. Therefore, the number of moles of reactants you start with will directly determine the number of moles of products formed, assuming you have an excess of the other reactants.

A circle has a circumference that is greater than 8 meters. The inequality 3.14 d greater-than 8 can be used to determine the possible lengths of the diameter of the circle. What are the possible values of d, the length of the diameter in meters?

Answers

Answer:

The possible values of d, the length of the diameter is d > 2.55 meters.

Step-by-step explanation:

The circumference of a circle is:

[tex]C=2\pi r=\pi\ d[/tex]

Here,

C = circumference

r = radius

d = diameter

It is provided that the circumference is greater than 8 meters.

That is,

a right triangle with an angle of approximately 53.1 is inscribed in the first quadrant of the unit circle with a horizontal length of 3/5 and a vertical length of 4/5 complete the table for the following trigonometric functions

Answers

Final answer:

In a right triangle with an angle of 53.1 degrees, and sides 3/5 and 4/5, the sine is 4/5, the cosine is 3/5, and the tangent is 4/3. aThese methods and results are a fundamental part of understanding trigonometric functions in Mathematics.

Explanation:

In this scenario, you were given a right triangle inscribed in the first quadrant of the unit circle. The angle of the triangle is given as 53.1 degrees, the horizontal length (adjacent side) is 3/5, and the vertical length (opposite side) is 4/5. We can calculate the trigonometric functions based on this. Trigonometry revolves around the relationship between side lengths of triangles and the angles they form.

Sine (sin) of an angle is defined as the ratio of the length of the side that is opposite the angle to the length of the longest side of the triangle (hypotenuse). Here, sin(53.1) = Opposite/Hypotenuse = 4/5.

The Cosine (cos) of an angle is defined as the ratio of the length of the adjacent side of the angle to the hypotenuse. So, cos(53.1) = Adjacent/Hypotenuse = 3/5.

The Tangent (tan) of an angle is the ratio of the sine of the angle to the cosine of the angle, which also equals the ratio of the opposite side to the adjacent side. Tan(53.1) = Sin(53.1)/Cos(53.1) = (4/5) / (3/5) = 4/3.

https://brainly.com/question/11016599

#SPJ12

Final answer:

The sine, cosine, and tangent of an angle in a right triangle inscribed in the first quadrant of the unit circle are respectively equal to the ratios of opposite/hypotenuse, adjacent/hypotenuse, and opposite/adjacent sides. So, in your case where the triangle has an angle of 53.1 degrees, horizontal length 3/5, and vertical length 4/5, sinθ = 4/5, cosθ = 3/5, and tanθ = 4/3.

Explanation:

In the right triangle you mentioned, the hypotenuse is the radius of the unit circle which is 1, the horizontal length (adjacent side, often represented as x) is 3/5, and the vertical length (opposite side, often represented as y) is 4/5. The quoted angle, usually symbolized as θ, is 53.1 degrees. With this information, we can calculate the trigonometric functions as follows:

Sine (sin) of θ is defined as the ratio of the opposite side to the hypotenuse. So, sinθ = y/h = 4/5 Cosine (cos) of θ is the ratio of the adjacent side to the hypotenuse. So, cosθ = x/h = 3/5 Tangent (tan) of θ is the ratio of the opposite side to the adjacent side. So, tanθ = y/x = (4/5) / (3/5) = 4/3

What is Box and whisker plot?

The lower and upper quartiles are shown on the left and right sides of a box and whisker plot, respectively. The interquartile range, which contains 50% of the data, is covered by the box. The median is the vertical line that divided the box in half.

We have a box and whisker plot.

Based on the position of the median value in the box plot, we may decide if a distribution is skewed or not. The distribution is right-skewed (or "positively" skewed") when the median is closer to the bottom of the box and the whisker is shorter on the lower end of the box.

A right-skewed distribution with a positive skewness is one in which the median is smaller than the mean. The median of a left-skewed distribution is bigger than the mean when the skewness is negative, on the other hand.

Here, the data is shorter on the lower end of the box.

Thus, the plot is positively skewed.

Karlen started painting the walls at 10:45 am, and he said that he could complete the job at 5:25 pm. His father said that five eighths of that time was enough to paint the walls. However, when Karlen finished the job, they noticed that it actually took him 80% of an hour longer than the time predicted by the father. How much longer did Karlen predict it would take than the time it actually took him to complete the job (what part of an hour)? Please help as soon as possible

Answers

Answer:

karlen predicted it will take 1.7 hours longer than he actually did

Step-by-step explanation:

If Karlen started painting the walls at 10:45 am, and he said that he could complete the job at 5:25 pm.

Which means he thought he would spend 6 hrs 40 minutes or 6⅔ hours or 20/3

Now, his father said ⅝ of that time was going to be enough to paint the whole wall.

Thus; estimated time by father to paint whole wall = ⅝ x 20/3 = 25/6 hours.

Now, it says karlen took 80% of an hour longer than the time predicted by his father to finish the painting.

Thus, karlen actually spent;

25/6 + 80/100 hours = 25/6 + 4/5 = 149/30 hours

Thus, since karen predicted he was going to spend 20/3 hours, the difference is;

20/3 - 149/30 = 1.7 hours

So karlen predicted it will take 1.7 hours longer than he actually did

Answers

Answer:7 sr 2

Step-by-step explanation:

The length of side GH in an isosceles right triangle where angle G is 45 degrees and side HI is the hypotenuse equal to 7, is 7/√2 or 7√2/2 when rationalized.

You asked about finding the length of side GH in a right triangle where angle G equals 45 degrees, and side HI equals 7. In an isosceles right triangle, the lengths of the two legs are equal. As angle G is 45 degrees, it indicates that triangle GHI is an isosceles right triangle. Using the concept that in such a triangle, the lengths of the legs are equal, since they correspond to the sine and cosine of 45 degrees, which both equal 1/√2.

Given that HI is the hypotenuse and GH is one of the legs, we can use the relationship between the sides: GH = HI * cos(45°) = 7 * 1/√2. Therefore, the length of side GH is 7/√2 or 7√2/2 when rationalized.
