What is the probability of rolling a 3 on a number cube and choosing a letter that is a vowel form the word MATHEMATICS?

Answers

Answer:

2/33

Step-by-step explanation:

1.Since a number cube has six sides, and the word mathematics has 11 letters, and there are four vowels in mathematics, the probability of rolling a 3 in a number cube is 1/6. The probability of choosing a letter that is a vowel in mathematics is 4/11.

2. You multiply them together. 1/6*4/11=2/33.

3. The answer is 2/33.

Step-by-step explanation:

So to solve for AC you'll want to find the hypotenuse for ACD. In order to do that, we need the length of AD. We can find it by using the pythagoram theorum. So 7²=A² + 5²=> 49=A²+25 so A =[tex]\sqrt{24}[/tex]

Now that we have AD we can find x which is A²=24+9=A=[tex]\sqrt{33}[/tex][tex]\sqrt{33} x^{2}[/tex]

Luke and Pedro work for Crown Carpentry. On Thursday, they each hung the same amount of wooden trim, but Pedro finished first. On Friday, they will work for the same amount of time hanging trim in a new movie theater. Will Pedro likely hang more trim or less trim than Luke?

please help

Answers

I think he’ll hang more because on Thursday, they both hung the same amount but Pedro finished first meaning he can hang trim faster than Luke. So if they both worked for the same amounth of time, for example if Luke worked for as much time as it took Pedro to hang trim on Thurday, Luke wouldn’t have been finished. I hope that makes sense!

I need help with this question.

Answers

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

Read another paragraph and graphic from the text “Overfishing the Oceans.” Then answer the question.
Overfishing is a problem that affects a whole ecosystem. A healthy ocean has a balance of different species. One problem with overfishing is that it takes away many of the top predator fish and disrupts this balance. Overfishing can also disrupt the marine ecosystem in other ways.

Based on the information in the paragraph and graphic, what might be a result of a decrease in tuna populations?
A. Sharks may have difficulty finding food.
B. A rise in squid and mackerel populations.
C. The balance in the food web would be disrupted.
D. All of the above are potential results of a decrease in tuna populations.

Answers

D- all of the above because sharks eat tuna, tuna eats mackerel and squid meaning if there’s nothing to eat them the population will just grow. And ofc the balance of the food web will be wack so all of the above

Example.

If Stefan has 1 bouncy ball, Hannah would have 20.

Formula.

Stephan's Amount + 19 = Hannah's Amount

Solving Your Problem.

We will do the same thing except replacing "1" with "b".

b = Stefan's Amount

b + 19 = Hannah's Amount

We are just adding 19 to his.

The outer layers of cells are dead. Dissolve it in liquid with sugar, called proofing, before mixing with the other ingredients. This removes the dead cells and activates the yeast.Instant yeast has been gently dried. Its outer cells are alive. It does not need to be proofed and can be mixed with other ingredients.This essay would benefit from transitional words and phrases. Choose the option below that uses transitions most effectively.A.Yeast makes bread rise. There are two types of yeast commonly used in bread making, active dry yeast and instant yeast. Either type can make good bread, but each has been processed differently and thus must be handled differently.Active dry yeast has been heat treated, and as a result the outer layers of cells are dead. Before mixing this kind of yeast with other ingredients, it must first be dissolved in liquid with some added sugar. This step, called proofing, removes the dead cells and activates the yeast.Instant yeast has been more gently dried. Unlike active dry yeast, its outer cells are still alive. Since it does not need to be proofed, it can be mixed directly into other ingredients.B.Yeast makes bread rise, including active dry yeast and instant yeast. Either can be used, but based on the fact that they are processed differently, they must be handled differently.First, active dry yeast has been heat treated. The outer layers of cells are dead because of it. Dissolve it in liquid with sugar, defined as proofing, before mixing with the other ingredients. This then removes the dead cells, and activates the yeast.Second is instant yeast, which has been gently dried. Its outer cells are alive in consequence. It does not need to be proofed and can be mixed with other ingredients.C.Yeast makes bread rise. For example, there is active dry yeast and instant yeast. Either can be used. They are processed differently, however, and must therefore be handled differently.Active dry yeast has been heat treated. Specifically, the outer layers of cells are dead. First, dissolve it in liquid with sugar, called proofing, before then mixing it with the other ingredients. This removes the dead cells and activates the yeast.Instant yeast has been gently dried. Its outer cells, in contrast to active dry yeast, are alive. At this point, it does not need to be proofed and can be mixed with other ingredients.D.Yeast, such as active dry yeast and instant yeast, makes bread rise. Subsequently, either can be used.
