what is the probability of rolling an odd number on one roll of dice

Answer:42.46444

Step-by-step explanation: 4.57×4.04x2.3

I think 42.46444 is the answer

The percentage uncertainty for each measurement, sum them, and apply this to the area, resulting in an uncertainty of approximately 0.0350 m².

To calculate the area of a rectangular room, you multiply the length by the width. In this case, we have been provided with the measurements for the length (3.955 "+/-" 0.005 m) and the width (3.050 "+/-" 0.005 m). Multiplying these measurements gives us the area of the room, albeit with some uncertainty due to measurement errors.

First, calculate the area using nominal values:

Area = Length x Width = 3.955 m x 3.050 m = 12.07275 m²

To compute the uncertainty in the area, apply the rule for the multiplication of quantities with uncertainties:

The percentage uncertainty for both the length and the width is:

Length: 0.005 / 3.955 = 0.001264 (about 0.1264%)

Width: 0.005 / 3.050 = 0.001639 (about 0.1639%)

Add the percentage uncertainties:

Total percentage uncertainty = 0.1264% + 0.1639% = 0.2903%

Apply this to the area:

Uncertainty in area = 0.2903% of 12.07275 m² ≈ 0.0350 m²

Therefore, the area of the room with its uncertainty is:

12.07275 m² "+/-" 0.0350 m² (approximately, we could round the nominal area to 12.073 m² and the uncertainty to 0.035 m² due to significant figures)

Answer:

Same gets 32 sweets.

Step-by-step explanation:

We have by proportion  4/5 = x/40    where x is the number of sweets that Sam gets.

5x = 4*40

5x = 160

x = 160/5 = 32 sweets.

Answer:

The measure of angle AOB is 36°

Step-by-step explanation:

- Point B is in the interior of ∠AOC

- That means angle AOB is a part of angle AOC

- Measure of angle AOC is 108°

- Measure of angle AOC is 3 times measure of angle AOB

- We need to find measure of angle AOB

* Lets solve the problem

∵ m∠ AOC = 3 m∠ AOB

∵ m∠ AOC = 108°

- Substitute m ∠AOC in the equation above

∴ 108 = 3 m∠ AOB

- Divided both sides by 3

∴ 36° = m∠ AOB

The measure of angle AOB is 36°

Answer: The measure of ∠AOB = 36°.

Step-by-step explanation:

Since we have given that

m∠AOC = 108°

and we need to find the measure of ∠AOB.

As we know that

[tex]m\angle AOC=3m\angle AOB\\\\108=3\angle AOB\\\\\dfrac{108}{3}=\angle AOB\\\\36^\circ=\angle AOB[/tex]

Hence, the measure of ∠AOB = 36°.

Answer:

Symmetry

Step-by-step explanation:

Because the two sides are equally the same. Basically identical.

well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?

we can simply put both fractions with the same denominator, by multiplying one by the other's denominator, so let's proceed,

[tex]\bf \stackrel{\textit{\large Marcus is taller}}{5~feet + \left( \cfrac{19}{24}\cdot \cfrac{16}{16}\implies \boxed{\cfrac{304}{384}} \right)}\qquad \qquad \qquad \stackrel{\textit{\large Ben}}{5~feet + \left( \cfrac{9}{16}\cdot \cfrac{24}{24}\implies \boxed{\cfrac{216}{384}} \right)}[/tex]

16. 10 ml of 20% saline and 40 ml of 10% saline

Step-by-step explanation:

A chemist takes x ml of 20% saline and y ml of 10% saline. In total, he takes

x + y ml that is 50 ml, so

[tex]x + y = 50.[/tex]

There are  [tex]0.2x[/tex] ml of salt in x ml of 20% saline and [tex]0.1y[/tex] ml of salt in 10% saline. There are [tex]0.12\cdot 50=6[/tex] ml of salt in 50 ml of 12% saline. Thus,

[tex]0.2x+0.1y=6[/tex]

15. We get the system of two equations:

[tex]\left\{\begin{array}{l}x+y=50\\0.2x+0.1y=6\end{array}\right.[/tex]

16. Solve this system. From the first equation:

[tex]x=50-y[/tex]

Substitute it into the second equation:

[tex]0.2(50-y)+0.1y=6\\ \\10-0.2y+0.1y=6\\ \\-0.1y=6-10\\ \\-0.1y=-4\\ \\y=40\\ \\x=50-y=50-40=10[/tex]

C/R = d.

Answer:

The answer is 10.

Step-by-step explanation:

Multiply both sides of the equation by 12.

12( 3/4x - 5/6) = 12 times 2/3x.

Distribute 12 through the parenthesis.

12 times 3/4x - 12 times 5/6 = 12 times 2/3x.

Reduce the numbers with greatest common divisor 3.

12 times 3/4x - 12 times 5/6 = 4 times 2x.

Reduce the numbers with greatest common divisor 4.

3 times 3x - 12 times 5/6 = 4 times 2x.

Reduce the numbers with greatest common divisor 6.

3 times 3x - 2 times 5 = 4 times 2x.

Calculate the product, 4 times 2x.

3 times 3x - 2 times 5 = 8x.

Calculate the product 3 times 3x.

9x - 2 times 5 = 8x.

Multiply the numbers - 2 times 5.

9x -10 = 8x.

Move the constant to the right by adding its opposite to both sides.

9x - 10 + 10 = 8x + 10.

Eliminate the opposites, -10 + 10.

9x = 8x + 10.

Move the variable to the left by adding its opposite to both sides.

9x -8x = 8x -8x + 10.

Now eliminate the opposites

9x - 8x = 10.

Collect the like terms by subtracting their coefficients.

(9-8)x

Subtract the numbers.

1x.

When the term has a coefficient of 1, it doesn't have to be written, so it's basically x.

Then, x will equal to 10!

Answer: Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

h(t) = 2t 2 – 11t – 10 is the answer

The value of h(t) is h(t) = 2t^2 – 11t – 10.

To add or subtract functions, just add or subtract the values at each point where it makes sense.

How to find h(t) = f(t) – g(t)?

Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:

Given : Dam A  f(t) = 5t^2 – 7t – 1

Dam B : g(t) = 3t ^2 + 4t + 9.

Then f(t) – g(t) = (5t^2-7t-1) -(3t^2+4t+9)

=> 2t^2 – 11t – 10.

Thus, h(t) = 2t^2 – 11t – 10.

[tex]15.5 \times \pi = 48.694686[/tex]

round it and you'll get to 48.7cm

Hope it helps :)

Sorry if not :(

Answer: A. 48.7 cm

Step-by-step explanation:

The circumference of circle is given by :_

[tex]\text{Circumfernce}=\pi d[/tex] , where d= diameter of the circle .

In the given [picture , we are given that the diameter of the circle = 15.5 cm

Then, the circumference of the circle will be :-

[tex]\text{Circumfernce}=\pi (15.5)\ cm[/tex]

Substitute [tex]\pi =3.14[/tex] , we get

[tex]\text{Circumfernce}=(3.14) (15.5)\ cm[/tex]

[tex]\text{Circumfernce}=48.67\approx48.7\ cm[/tex]

Hence, the approximate circumference of the circle = 48.7 cm

Thus , the correct answer is 48.7 cm  .

Answer:

Step-by-step explanation:

We can round off the values for estimation.

29,354 can be rounded off to 30,000, which is

[tex]3 \times 1 {0}^{4} [/tex]

Similarly, 6,156,782,221 can be rounded off to 6,000,000,000 which is

[tex]6 \times 1 {0}^{9} [/tex]

Now we divide these two terms.

[tex](6 \times 1 {0}^{9} ) \div (3 \times 1 {0}^{4} )[/tex]

[tex]6 \div 3 = 2[/tex]

so it cannot be options B or D.

[tex]1 {0}^{9} \div 1 {0}^{4} = 1 {0}^{5} [/tex]

Hence, by estimation, it is

[tex]2 \times 1 {0}^{5} [/tex]

times more.

The length of segment AD is found by subtracting the length of CD from that of AC, which gives AD = 18 - 5 = 13.

In this problem, you are given the lengths of segments AC and CD. The question is asking you to find the length of segment AD. This looks like a problem of segment addition in geometry. Segment addition postulate states that if a point B lies on a line segment AC, then the whole length of the segment AC equals the addition of AB + BC. In this case, however, we are given that the whole length AC equals 18, and a part of it, CD equals 5. To find the length of the unknown segment AD, we now need to subtract CD from AC. Therefore, using the segment addition postulate, we can solve this problem as follows:

AD = AC - CD

AD = 18 - 5

AD = 13

So, the length of segment AD equals 13.
