Algebra

Hi y’all. I am notoriously bad at math, somehow got scooted into intermediate algebra. I am stuck on one problem, and was wondering if anyone could show me why / how I am getting stuck. X2 -5x-6=0 I know that I need to find two numbers that will multiply to -6, and add up to -5. I found 2 & 3. But when I multiply negative 2&3, they become positive six. I can’t add one of them positive, one...

As a riddle, the answer is zero legs on the bus since the bus has wheels instead of legs. But as a maths problem; It's not a tricked question -- just a straightforward maths problem Confirmed answer is 10990 legs. § Let's say the whole situation simply : - There are 7 girls. - Each girl has 7 backpack - Each backpack has 7 big cats - Each big cat has 7 little small cats. § Question: How many legs are there in the bus? § Let's...

No. It is a very large number, but not infinite.

A cube has 6 faces, 8 vertices, 12 edges.

It depends a great deal on where you live and how well your home is insulated. Square feet is not a great help when planning the size of an air conditioner. It is very useful to also have the cubic feet in the home, along with the sizes and types of windows. Where I live in the northwest US, a 3-ton unit would do the trick easily, but then, we do not get the intensely hot, long summers as you might in...

the opposite of negative 18 is positive 18. It's just like absolute value. |-18| is 18 because 18 is 18 steps away from 0 so is -18 like how it is 18 away from 0 and not -18 away from 0. -18 away from 0 is not a thing. So therefore, the opposite of negative 18 is positive 18 because the opposite of negative is postitve....

2 and 3. In fact, 2 and 3 are the ONLY prime factors of both. 36 = 22 x 32. 144 = 24 x 32. ...

The term is written as "One millionth." As a prefix in SI measurements it is "micro". For example, 0.000001 grams is the same as 1 microgram. 0.000001 metres is called a micrometer but also has the special name "micron". Sometimes expressed as "zero point zero zero zero zero zero one" ...

Circumference divided by pi to find the diameter then divide that by 2 to give you answer!! Formula: R=c/pi/2 eg. circumference =60 so, 60 divided by pi = 19.098, then divide 19.098 by 2 to give you 9.549!! ...

In the personal sense, it means something negative in your personality like being negative (pessimistic) or not concentrating in school. In algebra it means a minus number below zero eg. -2 is 2 less than zero. An extra note - if the equation is 5--5 (five minus minus five) then just add five because two minuses or negatives equal a plus or positive. Sorry if I got the wrong meaning of what you asked! ...

To cube a number means simply to multiply that number by itself 3 times. To work out 40 cubed you would simply go: 403 = 40 x 40 x 40 40 x 40 = 1,600 1,600 x 40 = 64,000 403=64,000 Therefore, 40 cubed equals 64,000. The phrase "multiply that number by itself 3 times." can cause confusion. Sometimes, instead of multiplying it thrice (the number itself) others, due to confusion, just multiply the number by 3... take note it's cube... What do you get if you...

To convert a fraction (or decimal) to percentage, multiply by 100, thus: 8/25 = 8/25 x 100% = 32% ...

It depends on what kind of label it is and what kind of period it is.

A protractor, compass, speed square, goniometer, theodolites, sextant, or angle finder can be used to measure angles. A protractor is a circular or semi circular instrument for measuring angles and some have existed from ancient times. A half circular protractor is marked for 180 degrees and a full circle for 360 degrees. Protractors usually have two sets of numbers going in opposite directions, so be careful which side you use. When in doubt you should ask yourself is the angle greater or...

1 foot equals 0.3048 meters 18 feet X 0.3048 = 5.4864 meters

Sometimes you can't simplify a mixed fraction, but simplifying a mixed fraction is just like simplifying an original fraction. For example: You can not simplify 1 and 3/4, because 3/4 can not be simplified. But 1 and 10/16 can be simplified. To do this: You take the actual fraction part 10/16 Find a LCD (Least Common Denominator) for this it is 2 Divide both the reciprocal and denominator by this number 10 divided by 2=5, 16 divided by 2=8 Put the new divided numbers where...

The percent sign % can be defined as "divide by 100". So the decimal of 140% would be 140/100 or 1.4 So if you wanted to know what 140% of any number was you could multiply by 1.4 i.e. 140% of 50 is 50 x 1.4 = 70, or since multiplication is distributive you could also do this (140 x 50)/100 which will also give you 70 1.4 ...

Hovercraft are becoming more common, and as technology improves, they have become quieter and more affordable. Hovercraft are very useful for rescuing people from floods, mud, ice and sand - as global warming increases the risk of flooding, as witnessed in Pakistan and China, hovercraft can play a very important role. Leisure hovercraft are now available, see the related link below, and small patrol hovercraft can play an important role in homeland security, particularly for patrolling coastal areas. Small race hovercraft have very...
