The main stalk seems limp, and the supporting stalk's leaves are now flat against the soil.

x^2 + 4x + 2 =0

***I rounded my final answers to the nearest 1000th***

x1 = -0.586

x2= -3.414

2x - 5y = 4

3x - 4y = -1

One number is 30 more than another number. If the difference between the two numbers is equal to 8. What are the numbers?

What number is 15% of 120

10 - 3x+5/6 = 47/12 - x/2/4 last term reads x over 2 divided by 4

3x/8 -7/10 - 12x-5/16 - 2x-3/20 + 4x+9/4 + 7/80 = 0

5 + x/4 = 1/3 (2 - x/2) - 2/3 + 1/4 (10-5x/3)

10 - 3x+5/6 = 47/12 - x/2/4 last term reads x over 2 divided by 4

3x/8 -7/10 - 12x-5/16 - 2x-3/20 + 4x+9/4 + 7/80 = 0

5 + x/4 = 1/3 (2 - x/2) - 2/3 + 1/4 (10-5x/3)

U = {I, II, III, IV, V, VI, VII, VIII}

A= {I, II, IV, V}

B= {II, III, V, VI}

C= {IV, V, VI, VII}

I do not know how to enter the functions, so I typed them in word format.

1. A intersection ( B Union C)

2. ( A intersection B) Union C

3. ( A complement B) complement

Determine which of the collections are not well defined and not sets

1. A collection of US Presidents--defined; set

2. The collection of part-time and full-time students currently enrolled in your college--not defined; { }

3. The collection of the 5 worst US presidents--not defined, { }

4. The collection of elderly full-time students currently enrolled at your college--not defined; { }

If I got any wrong, please explain. Thanks.

You have two samples of the SAME organic compound one weighing 8.28 g and the other weighing 15.07 g. Would the mass of EACH element in the sample weighing 15.07 be the same as, less than, or more than the mass of the 8.28 g organic compound?

Please explain answer. Thank you.

If a chemical compound increased from 8.28 g to 15.07 g would the mass of each element remain the same, become less than, or more than the previous sample?

Please explain. Thanks

A sample of an organic compound (known to be composed of only carbon, oxygen, and hydrogen) weighing 8.28 g is found by elemental analysis to contain 4.70 g of carbon, 2.52 of oxygen, and 1.06 g of hydrogen. What is the fractional, decimal, and percentage composition of the 3 elements?

I divided each of the elements from the total weight and multiplied by 100 and got the following answers:

Carbon-- 57/100 (fractional) 0.57 (decimal) and 57% (percentage)

oxygen-- 3/10 (fractional) 0.30 (decimal) and 30% (percentage)

hydrogen-- 13/100 (fractional) 0.13 (decimal) and 13% (percentage)

Please note any errors. Thanks

I need help with the following problem:

You obtain the mass of an organic liquid "by difference" on an analytical balance using a 50.0 ml volumetric flask. Your weights are 102.5608 g empty and 139.7432 g containing the 50.0 ml of the organic liquid. A chemistry reference book gives the density for this organic liquid as 0.733 g/ml at the temperature of your measurements.

a) calculate the experimental density

b) calculate your experimental percent error using 0.733 g/ml as the true density

Please explain work. Thanks

I know that biological adaptations are inherited and cultural adaptations are learned, but I'm not sure if any similarities exist between the two. Could someone shed some light on this? Thanks.

Would it be the first. second, or third syllable?

1/x-1 + 1/2 = 2/x^2-1

The worlds largest taco had 1kg of onions per every 6.6 kg of grilled steak. If the total weight of the taco was 617.6 kg. what was the ratio of onions and grilled steak to the nearest tenth of a kg?

I got this as an answer on a previous post, and one thing doesn't make sense---where did the 24y come from?

2y^2 +13y -132 = 0

2y^2 + 24y - 11y - 132 = 0 2y(y + 12) -11(y + 12) = 0

(2y - 11) (y + 12) = 0

2y - 11 = 0

2y = 11

y = 11/2

y = 5 1/2

y + 12 = 0

y = -12

2y^2 +13y -132 = 0
