Step-by-step explanation:

Stem | Leaf.

2 | 6

3 | 7

4 | 8

3 | 3

4 | 9

2 | 6

1 | 9

2 |6

4 | 8

if you organize this from least to greatest, this is your answer

Stem | Leaf

1 |9

2 |6 6 6

3| 3 7

4| 8 8 9 The Stem represents the Tens

place while the Leaf represents

the ones place, the 1, 2, 3 and 4

stand for two digit numbers

meaning 3 stands for 33 and 37,

good luck! ;)

Answer:

[tex]36[\cos{127^\circ}+i\sin{127^\circ}][/tex]

Step-by-step explanation:

Polar form:  [tex]z=r(\cos(\theta)+i\sin(\theta)[/tex]

To multiply two complex numbers in polar form, multiply the r values and add the angles.

[tex]w_1w_2=36\left[\cos{(95^\circ+32^\circ)}+i\sin{(95^\circ+32^\circ)}\right]\\\\=36[\cos{127^\circ}+i\sin{127^\circ}][/tex]

Answer:

5x2+6x-6=0

Step-by-step explanation:

Standard form is ax2+bx+c=0

We add 6x to both sides and we get:

5x2+6x-6=0

Got a 100% on edge quiz

Answer:

558 weeks

Step-by-step explanation:

let x = number of weeks

this equation can be derived from the question

2 + 1x = 560

collect like terms

x = 560 - 2

x = 558

Answer:

Step-by-step explanation:

Perimeter= all sides added together

so in this case

3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2

now you may be wondering why i put two 2x's, two 2+x, and two x-1  , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 )  so you need to account for all sides.

so lets simplify this huge equation!

3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2

3x+1 = 8x - 1 + 2 - 1 + 2

3x + 1 = 8x + 2

-3x on both sides

1 = 5x + 2

-2 on each side

-1 = 5x

x = -1/5

Answer:

1.1

Step-by-step explanation:

1 in probability means always so anything greater than 1 is meaningless

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.  

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

[tex]z^{2} = 28.31^{2} - 25^{2}[/tex]

z = 13.29

Answer:

11

Step-by-step explanation:

All angles on a triangle equal 180. 80+60=140.

Now to solve for x, we set it to equal 40 for 180-140.

40=3x+7. 40-7=33

33=3x 33/3=11

x=11

Answer: 601 square inches

Answer:

Supplier A: 5.25 per bushel and deliver fee of 3 per bushel

Supplier B: 6.50 per busher and flat delivery fee of $1500 each week

500 bushels of grain each week.

Supplier A: 5.25x + 3x = 5.25(500) + 3(500) =  2,625 + 1,500 = 4,125

Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750

Supplier B would cost more if the company buys 500 bushels of grain per week.

Answer:

a = 6 , b = -9

Step-by-step explanation:

2a + b = 3

b = -2a + 3

3a + 2(-2a + 3) = 0

3a - 4a + 6 = 0

-a = -6

a = 6

2(6) + b = 3

12 + b = 3

b = -9

Answer:

b

Step-by-step explanation:

because if u divide-5/-5 u will get 0 answer

Answer:

B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

the answer is B because to find the cost for just 1 ounce would be the amount of money divided by the original amount of ounces.

2.88/12 = 0.24

3.24/14 = 0.2314...

4.52/18 = 0.2511...

4.75/20 = 0.2375

Remember that she wants to SAVE money so the best answer would be B because she is only spending less than 24 cents an ounce.

Answer:

Brand B because it is less than 0.24 per ounce

Step-by-step explanation:

Brand A is 0.24 per ounce

Brand B is 0.2314 per ounce

Brand C is 0.251 per ounce

Brand D is 0.2375

Answer:

Answer:

5/44

Step-by-step explanation:

3 plus 4 plus 5 is 12 so for a white it is 4/12 or 1/3

then you take out the white baseball and you want a green which is 5/11 3 red 3 white 5 green

5/11 times 1/3 is 5/33

so the odds of picking both is 5/33

Step-by-step explanation:

Answer: 59049 or 4.64

Step-by-step explanation: 59049 is the answer to 3^sqrt(100), but I wasn't totally sure if you meant ^3sqrt(100) or not so I solved both.

3^sqrt(100) = 59048

^3sqrt(100) = 4.64158
