Explain how to solve the equation and how to check the solution.
40 = 8y


there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Look at the picture and answer the question: What is the length of QS?

Answers

Step-by-step explanation:

firstly draw the triangle and label it. (you will find the picture down)

Now this remind us with the cosine rule. (you will find the picture down)

This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.

So using that rule we can say that:

[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]

square root both sides, so you will have QS alone in one side.

QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]

plug in the values we have and y=this will yield:

QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10

You have a deck of cards and draw three cards one after the other without replacing the cards. What is the probabilities of drawing three tens? (Pls give a good explanation & the answer lol)

Answers

Answer:

The probability of drawing 3 tens one after another without replacing them is 1/5525

Step-by-step explanation:

In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52

Therefore:

The first draw, P(10) = 4/52  

Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.

The second draw, p(10) = 3/51

Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.

The third draw, p(10) = 2/50

Hence, the probability of drawing out 3 number 10 cards without replacement is:

4/52 * 3/51 * 2/50 = 1/5525  

The probability of drawing 3 tens one after another without replacing them should be 1/5525.

Calculation of the probability:

Since  we know that

In a pack, there are 52 cards and there are 4 cards that are 10,

so the probability of drawing one ten [p(10)] = 4/52

Now it should be left with 51 cards in total and 3 cards of 10.

So, The second draw, p(10) = 3/51  

and, The third draw, p(10) = 2/ 50

Thus,  the total probability is

= 4/52 * 3/51 * 2/50

= 1/5525

Kathryn is cooking pancakes. The recipe calls for 3 2/9 cups of flour. She accidentally put in 5 4/5 cups. how many extra cups did she put in?

Answers

subtract
29/5 - 29/9
261/45 - 145/45
116/45

Answer

So basically you need to subtract 5 4/5 - 3 2/9

then you do all this:

= (5-3) + (4/5 - 2/9)

= 2+ 4x9/5x9 - 2x5/9x5

= 2 + 36/45 - 10/45

= 2 + 36/45 - 10/45

= 2 + 26/45

= 2 26/45

So then the answer is 2 26/45

Aight so...

1) 16

2) 36

3) 125

4) 64

Step-by-step explanation:

So when you have a number being squared or with an exponent of 2, all you're doing is multiplying it by itself. Same thing if it's being cubed, or it has an exponent of 3. You'll multiply it by itself 3 times. For example, 6^2 is 36 because 6 x 6 is 36. Hope this helps, I dunno if it did but I hope so ^^
