My first cheerleading competition, along with all of the practices and events leading up to it, was a nerve racking, yet extremely exciting experience. I don't know if that is the right subject/verb agreement. It is a topic sentence for a narrative paragr...

When I joined cheerleading in the seventh grade, it was stressful because the majority of the girls were already extremely good at stunts and gymnastics while everything was new to me. should there be a comma between gymnastics and while?

In my sentence I typed, "I did not have a clue what to expect," and the computer said that it was not proper grammar. Should it be, "I did not have a clue of what to expect?" >> sorry for all the questions this is part of a final and we didn't do any proo...

Is excitedness a word? Any better words?

Find the value of x. x / x+5 = x-4 / x the book says the answer is 20, but im not getting that. I crossed multiplied and got x^2=(x+5)(x+4) and then multiplied that out x^2 = x^2 + 9x+ 20 and then 9x=20.. what am I doing wrong?

Show that the given proportions are equivalent. a+c / b+d = a-c / d-b and a / b = c / d

wow. i can't believe i forget this from last year. 5x^2 - 11x - 36 = 0 theres some kind of box trick or somethin to factor that but i forget!

if you have two similar polygons and the scale factor is 3:5 and 12 times square root of 3 is one side, what is the cooresponding side

if you have two similar triangles and the scale factor is 3:5 and 12 times square root of 3 is one side, what is the cooresponding side

how do Al and Cl ionically bond with each other? I think its AlCl3 am i right?

One triangle has vertices A, B, and C. Another has vertices T, R, and I. Are the two triangles similar? If so state the similarity and the scale factor. AB- 6 BC- 8 AC- 10 TR- 10 RI- 7.5 TI- 12.5

Write the formula for each Ionic compound. *barium nitrate

what is the approx. atomic weight for Boron? (to the nearest tenth)

1. The percentage of a composition is equal to ???. 2. A compound's molecular formaul is numerically equal to its ??? Help!! Thanks =]

USE THE INFORMATION TO DECIDE IF TRIANGLE ABC IS ACUTE, RIGHT, OR OBTUSE AC = 13 BC = sq rt. 34 CD = 3 I know the answer is obtuse but I don't know how to get there. The sq rts threw me off

1. The sides of a triangle have lenghts x, x+4, and 20. Specify those values of x for which the triangle is acute with the longest side 20. 2. use the information to decide if triangle ABC is acute, right, or obtuse. AC=13, BC= sq. rt. 34, CD=3 >>i know t...

I know this might sound easy... but i need these problems for bonus and i want to make sure they are right Silver nitrate reacts with strontium chloride in an aqueous precipitation reaction. What are the formulas of silver nitrate and strontium chloride?...

Whew. long question. Barium carbonate is the source of barium compounds. It is produced in an aqueous precipitation reaction from barium sulfide and sodium carbonate. (Barium sulfide is a soluble compound obtained by heating the mineral barite, which is b...

those are proportions by the way

oooooh! i was wondering what i did. thank you =]

whoops did it again lol.. no its a-c / b-d ...but i still don't know how to do it

yeah i get it.. thanks some times i have brain farts and once i see it written out im like.. oh i should have known that. thanks again!!

umm... i don't remember how to do any of it. like to factor and get the ( ) ( ) can you tell me how to do that

ooh.. damon how did you get the (5x+9)(x-4) = 0 that's what i need to know

it the smaller side.. bt i don't know how to do the sq root

take water for example... when its cold.. water freezes (solid).. then warmer it melts(liquid).. then at 100 degrees c it boils (steam/gas)

sorry i meant to type: the percentage composition of a compound is equal to __________. for # 2 the whole question is a.) A compound's molecular formula is numerically equal to its _______ b.) THis means that the molecular formula can be determined given...

3x+4(x-2)=27 3x+4x-8=27 7x-8=27 7x=35 x=5

the answer is C 3x+4(-x-2)=-11 3x-4x-8=-11 -1x-8=-11 -1x=-3 x=3 y= -(3)-2 y=-5 any questions?

set it up like this x-2=2x then x=-2
