How much is 60x30?
Well, to do this mentally is fairly easy. If you take 6 x 3 it equals 18. Then take the 0's (Both of them) and add it to 18. Thus making 60 x 30 equaling, 1,800.
How many seconds in thirty minutes?
Oh, dude, you're really testing my math skills here. So, like, there are 60 seconds in a minute, right? And you want to know how many seconds in 30 minutes? Well, that's just 30 times 60, which is like 1800 seconds. Easy peasy lemon squeezy.
Which is the best estimate for the product 63x29?
60 x 30 = 1800
What is the area of a wall 60 feet long and 30 feet wide?
well its 60x30 and that's 1800. so the answers 1800! ~Thanks it helped alot :)~

How much is the area of a land measuring 70'Length x40'widthx60'lengthx30'width?
Area is two dimensions. You've given four, defining a hypervolume of 70x40x60x30 = 5,040,000 ft4 (hypercubic feet). If you mean TWO areas, it's just a matter of simple multiplication, which is left as an exercise for the student: 70x40 = ___ ft2 (sq.ft., square feet) 60x30 = ___ ft2 (sq.ft., square feet)
What is Partial-product method for 67x34?
To use the partial product method for the problem 67x34, first look at this problem like this: 60 + 7 x30 + 4 Then, simply multiply each of the top numbers by each of the bottom numbers. Once you have four different products, simply add these four numbers together to get your answer. For example, this problem would be solved as followed: 60x30 = 1800 60x4 = 240 7x30 = 210 7x4 = 28 1800 + 240 + 210 + 28 = 2278
How many typewritten pages of information are stored in a 4G-byte memory system?
30 line double spaced with 10 chars per inch with one inch margins would be about 65x30 bytes. 60x30 is 1800 so to make the math easy, let's say 2000. 2G-byte of memory divided by 2000 is 1 million pages, so a 4 Gig memory stick can hold 2 million pages of straight text, not formatted. Each volume of the Encyclopedia Britanica is about 1000 pages, Say a set of Encyclopedias are 25 volumes(making the math easier) So 2000 volumes divided by 25 = 80 complete sets of that encyclopedia. One thing is for certain.... It is not infinite.
How many seconds in thirty minutes?
Oh, dude, you're really testing my math skills here. So, like, there are 60 seconds in a minute, right? And you want to know how many seconds in 30 minutes? Well, that's just 30 times 60, which is like 1800 seconds. Easy peasy lemon squeezy.
How do you convert roof angle to roof pitch?
The quick and easy way is to purchase a speed square ($8). It has pitch and angles on it. Next a bit more of an investment is to purchase a Construction Master calculator($100). This is an invaluable tool for the building trade.Other than that you will need to use a trigonometric function. This will require a tangent table that can be found in a Trigonometry book or on a scientific calculator.IE. If you have an angle of 18.5 you will need to know the tangent of that angle. First you will need to understand how degrees are represented in the chart. If you look at the Trigonometric functions table you will find that the degree's are represented inn°n'. in this format for example 18d30' means 18 degrees and 30 minuets which is a term used for fractions of a degree. As on a clock the minuets represent 60 units so you will need to convert the decimal value to minuets. So 60(for our minuets value)/ (divided by)1 (for our decimal value) X.5 (our fractions of a degree)=30' now we have 18°30'The pitch is represented as 12 units of run (horizontal) and n units of rise (vertical) to solve for n the formula would be the tangent of the measured angle times the run (12) = the rise. Therefore the tangent of 18°30' is .3346 times the run 12 = 4.0152 or 4/12 (4 in 12) pitch. For each 12" out you go 4" up.Converting a roof pitch to roof angle:IE. a 4 in 12 pitch. Formula will be the opposite over the adjacent = the tangent of the angle you are looking for. In this case 4 is the opposite and the 12 is the adjacent. therefore we have 4/12 or 4 divided by 12 that = .33333 looking at the tangent of this fraction we will find it falls between .3314 and .3346 the angle for .3314 is 18d20'00" and .3346 is 18d30'00". you have to be looking at the Nat. tangent table to understand this part. There is more, in this format 18d20'00" means 18 degrees and 20 minuets 0 seconds which is a term used for fractions of a degree. As on a clock the minuets and seconds represent 60 units each so it will need to be converted to decimal value. So 1 (for our decimal value) / (divided by) 60(for our minuets value)X20(number of minetus)=.3333 or .3333° and 1/60X30=.5 or .5° so the angle for a 4 in 12 pitch is between 18.3333° and 18.5°.Now a bit more to narrow it down. our tangent for a 4/12 was .3333 falling between .3314 and .3346 the difference between the 2 choices is 32 units. the difference between the 2 angles is 10'(minetus) so for each unit of difference you have 10 divided by 32 = .3125' (minutes per unit) now from .3314 to our tangent of .3333 you have 19 units thus 19x.3125'=5.93' now you need to add this to the first angle of 18d20'00" for a total of 18d 25.93' so converting the minutes to decimal 1/60x25.93=.4321 for a total of 18.4321°. The construction Master gives the answer of 18.43 in about 6 seconds, the speed square about 3 seconds.Concluding: if a Construction Master is not in the budget buy a speed square.Short list of angles/pitch4.76°=1/129.46°=2/1214.04°=3/1218.43°=4/1222.62°=5/1226.57°=6/1230.26°=7/1233.69°=8/1236.87°=9/1239.81°=10/1242.51°=11/1245°=12/12
