Math and Arithmetic

To calculate crank length in slabs, you typically determine the amount of reinforcement required for tensile strength and then apply the appropriate lengths based on the design codes. The crank length is usually calculated as a function of the effective depth of the slab and the distance from the support to the point where the bending moment is critical. Generally, the crank length can be taken as a fraction of the span or can be based on specific design guidelines that consider the slab's thickness and loading conditions. It's important to ensure that the cranks are properly anchored into the slab to effectively transfer forces.

In the number 489, the digit 4 represents 400, as it is in the hundreds place. In contrast, in the number 5741, the digit 4 represents 40, since it is in the tens place. Therefore, the value of the digit 4 in 489 is significantly greater than its value in 5741.

2 3/4 X 4/5

1. Convert to Improper Fractions.

11/4 X 4/5

2. Cancel down by '4'

11/1 X 1/5

3' Multiply numerators and separately denominators.

11/5

4. Convert to mixed number/fraction

2 1/5 The answer!!!!!!

I have 1 quart how much more do I need to have 1.o6

It sounds like the asker needs to read the section in the text to understand fractions.

3.100 in fractions is very easy. To get rid of the decimal point, you divide it by a denominator that is a 1 followed by an equal number of zeros as are after the decimal point. 3.100 becomes 3100 / 1000. 3100/1000 can be reduced to 31/10.

The steps used to convert decimals to fractions are always the same. Learn those steps and you will have a foundational skill for more advanced math.

Another way to do this is by multiplying by a fraction equal to one.

3.100 x (1000 / 1000) = 3100/1000

YES!!!

The 'x-axis' is by convention the horizontal axis.

It follows that the 'y-axis' is the vertical axis.

This is for a 2-dimensional graph.

In a 3-dimensional graph , drawn on paper ( 2 -dimension) , there is a 'z-axis' . This is shown as an angled line, going 'up' from left to right.

All three axes intersect at the origin.

The coordinates are ( x,y,z,) in that order. The origin is ( 0,0,0).

Actully we learnt this in class and the true answer is 1.738724282

189 ÷ 16 = 11.8125 (11 times with 13 remaining).

4.464666.....

Is Rational it can be converted to a Ratio/Fraction/Quotient.

P = 4.4646666...

Let 1000P = 4464.66666...

10000P = 44646.6666

Subtract

9000P = 40182

P = 40182/9000

Cancel down by '3'

P = 13394/3000

Cancel down by '2'

P = 6697/1500 Done!!!!!

YES!!! A Fraction is a RATIO , hence it is RATIOnal.

NB Irrational numbers are those decimals that CANNOT be converted to a Ratio/Fraction/Quotient.

pi ~ 3.141592..... is the most famous Irrational Number.

To find out what 700 is 10 times as much as, you divide 700 by 10. This calculation results in 70. Therefore, 700 is 10 times as much as 70.

Oh, dude, seriously? Okay, so there are 10 millimeters in a centimeter, so if you have 37 centimeters, you just multiply that by 10 to get 370 millimeters. It's like converting dollars to cents, but with metric units. Easy peasy.

y = x^(2) + 4

If you plot it on a graph paper, you will find it produces a curved linea. Hence NOT linear.

On a graph '

A linear Equation produces a Straight line

A Quadratic Eq'n produces a Curved line.

Oh, dude, you're hitting me with some math now? Okay, so if you wanna sound all fancy, you can say "x divided by 4" or just keep it real and say "a number divided by 4." Either way, it's like x/4 or n/4, you feel me? Math, man, it's a trip.
