How to divide decimals

Answer:

0.0037

Step-by-step explanation:

Because 36/9643 cannot be simplified down any further, the only other way to describe it is as a decimal which is ~0.0037.

There are 20 marbles, and 12 of them are yellow; therefore, the number of yellow marbles does not equal the number of marbles, nor does the number of yellow marbles equal the number of yellow marbles because they are yellow.

I There can only be 31 marbles in the bag, since 30 marbles is the most number that each person can have equitably, plus one extra marble. As a result, the first response is A. Since 60 is divisible by 2, 3, and 5, plus 1 (leaving 1 remaining), 61 might also be a conceivable number of marbles in the bag.

The likelihood of selecting a ball from a bag is calculated by dividing the total number of balls by the quantity of that color. As a result, the likelihood of a red ball in the first case is 3/9, or 1/3. The likelihood of selecting a second ball if that ball is now eliminated is 2/8 or 1/4.

One less than the given number is known as preceding number whereas one more than the given number is the succeeding number.

The logics followed in order to find them:

Base numbers work exactly the same as base 10 numbers (the ones we use on a daily basis).

Take for example, in a decimal system, we have 10 digits available:

0,1,2,3,4,5,6,7,8,9.

When counting, when we get to the 9, we start over again, but writing a 1 to the left.

0,1,2,3,4,5,6,7,8,9,10,11,12....20,21,22,23....,90,91,92,93,94,95,96,97,98,99,10

When reaching 99, we have no more digits to use, so we start the count again and go from 99 to 100.

The same works with any other base number, take for example the base 7 number.

When counting in base 7, we only have 7 digits available: (0,1,2,3,4,5,6) So when 0_{7},each the digit 6, we go immediately to 10, like this:

It went from 6 to 10 and from 16 to 20. This is because in base 7, there is no digits from 7 to 9, so we have directly to 20.

So, if working with decimal numbers, the previous value for 640 would be 639, but notice that in base 7,

There is no such thing as the digit 9, so the greatest digit we can use there 6,

Therefore, the previous value for the number would be. The next number would be because the 1 does exist for a base 7 system.

Therefore , the solution of the given problem of slope comes out to be

line's equation is y =.1333 x + 1.55.

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).If you look at the line from left to right, a line that is moving up will have a positive slope and a line that is moving down will have a negative slope.

Here,

Given : f(x) =4 +x

The line's "intercept" of the y-axis marks the location of the y-intercept. It also makes sense because a player with a 25 cm heel to toe measurement is about 1.55 metres tall. This is most likely.

Any line has the equation y=mx+b (m=slope, b=y-intercept).

Finding two spots on this line where it crosses will reveal the slope of the line. I'll use the numbers (25.5, 1.6) and (26.25,1.7).

=> (y(2)-y(1)) / (x(2)-x(1))

=> m 1.7 - 1.6 / 26.25 - 25.5

=>.1/.75 =.13333 is the formula to calculate the slope.

At roughly 1.55m, this line crosses the y-intercept.

This line's equation is y =.1333 x + 1.55.

From the question, we have the following parameters that can be used in our computation:

The triangle

Using the law of cosines, we have the following equation:

t² = x² + y² - 2xy * cos(T)

Substitute the known values in the above equation, so, we have the following representation

44² = 32² + 24² - 2 * 24 * 32 * cos(T)

Evaluate the products and exponents

1936 = 1600 - 1536 * cos(T)

So, we have

Answer:

Step-by-step explanation:

We can start solving the problem by using the formula for compound interest:

A =[tex]P(1+\frac{R}{n})^{nt}[/tex]

Where A is the final amount, P is the initial principal, R is the interest rate, n is the number of times the interest is compounded in a year, and t is the number of years.

Given that the interest he earns during t = 0.5 to t = 1.5 is 1.0816 times the interest he earns during t = 0 to t = 1. We can use this information to set up an equation as follows:

[tex]P(1+\frac{R}{4})^{2}[/tex] = [tex]1.0816*P(1+\frac{R}{4})[/tex]

We can simplify this equation by canceling out the P and the (1+R/4) on the right side:

[tex](1+\frac{R}{4})[/tex] = 1.0816

We can then solve for R:

[tex]\frac{R}{4}[/tex]=[tex]\sqrt{(1.0816)-1}[/tex]

R = [tex]4(\sqrt{(1.0816)-1)}[/tex]

R ≈ 0.08, is the exact value of R.

Given are the functions as follows -

p(x) = - 5x + 5

q(x) = - 4x - 2

We can write -

(p о q)(5) = (- 5x + 5)(- 4x - 2)

(p о q)(5) = - 5x(- 4x - 2) + 5(- 4x - 2)

Answer:

To find the cost of a hot dog and hamburger, we can set up a system of equations based on the information given. For example, let x be the cost of a hot dog and y be the cost of a hamburger. Then we have:

4x + 7y = 68 (equation 1)

7x + 3y = 67 (equation 2)

We can use substitution or elimination methods to solve the system of equations.

Substitution method:

Solve equation 1 for y in terms of x: y = (68 - 4x)/7

Substitute this expression into equation 2: 7x + 3((68 - 4x)/7) = 67

Simplifying and solving for x: 7x + 3(68 - 4x)/7 = 67

7x + 204 - 12x = 469

-5x = -401

x = 80

Substitute x = 80 back into equation 1: 4(80) + 7y = 68

320 + 7y = 68

7y = -252

y = -36

Therefore, the cost of a hot dog is $80, and the price of a hamburger is $-36 (which is not possible, it could be a typo or mistake in the given information)

A polygon having three edges and three vertices is called a triangle. It is one of the fundamental geometric forms. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

The properties of a Triangle are :

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right.

In triangle ΔABC

∠B = 44° and ∠C = 17°

So, The sum of angles of a triangle is 180°

Therefore,

∠A + ∠B + ∠C = 180°

The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle.

Using a left-hand approximation means that we will use the left endpoint of each interval to approximate the area under the curve.

a) Using 4 boxes:

The interval from 0 to 2 can be divided into 4 equal parts, so each part has a length of 0.5.

The height of each box will be the value of y at the left endpoint of each interval.

The area of each box can be calculated as follows:

For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.5 * 1 = 0.5.

For the second box, the left endpoint is (0.5, 2) and the height is 2(0.5) + 1 = 2.5. The area is 0.5 * 2.5 = 1.25.

For the third box, the left endpoint is (1, 3) and the height is 2(1) + 1 = 3. The area is 0.5 * 3 = 1.5.

For the fourth box, the left endpoint is (1.5, 4) and the height is 2(1.5) + 1 = 4.5. The area is 0.5 * 4.5 = 2.25.

The total area is the sum of the areas of all the boxes, so the total area is 0.5 + 1.25 + 1.5 + 2.25 = 5.

b) Using 8 boxes:

The interval from 0 to 2 can be divided into 8 equal parts, so each part has a length of 0.25.

The height of each box will be the value of y at the left endpoint of each interval.

The area of each box can be calculated as follows:

For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.25 * 1 = 0.25.

For the second box, the left endpoint is (0.25, 2.5) and the height is 2(0.25) + 1 = 2.5. The area is 0.25 * 2.5 = 0.625.

For the third box, the left endpoint is (0.5, 3) and the height is 2(0.5) + 1 = 3. The area is 0.25 * 3 = 0.75.

And so on, for all 8 boxes.

The total area is the sum of the areas of all the boxes, so the total area is 0.25 + 0.625 + 0.75 + ... + 3.375 = 5.125.

So, the area between the x-axis and the curve y = 2x + 1 on the interval (0, 2) can be approximated as 5 or 5.125 depending on the number of boxes used.
