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?
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

Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.
Look at the picture and answer the question: What is the length of QS?
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

Simplify these exponents
1) 4^2
2) 6^2
3) 5^3
4) 2^6
Answer:
1.) 16
2.) 36
3.) 125
4.) 64
Step-by-step explanation:
multiply the base however many time it says so 4^2= 4*4=16 2^6=2*2*2*2*2*2=64
Answer:
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 ^^

Answer:
So for box 5 you would say that the weight of the box (48) plus the movers weight (185) is less than or equal to the amount of weight the elevator can hold which represents the 2,000. The last box could be something like "Amanda is shipping a 48lb T.V. the sound bar it came with and speakers totals to 180lbs. Amanda can't ship these items if they exceed 2,000 pounds total. Create an inequality to show if Amanda will be able to ship all these items without going over the allowed weight.

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)
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
