1 upon 8 of a number equals 2 upon 5 divided by 1 upon 20 what is the number

Answer»

Step-by-step explanation:

Let the REQUIRED number be X.

ATQ,

$\frac{1}{8} \times x = \frac{2}{5} \div \frac{1}{20}$

$=>\frac{x}{8} = \frac{2}{5} \times \frac{20}{1}$

$=>\frac{x}{8} = \frac{8}{1}$

$= > x = 8 \times 8$

$= > x = <klux>64</klux>$

10.	Basic formula for finding angle between hour and minute hand
Answer» Clock angle PROBLEMS relate two different measurements: angles and time. The angle is typically measured in degrees from the mark of number 12 clockwise. The time is USUALLY based on 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees PER minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute.

11.	Different statistical test used for remote sensing validation
Answer» There are many statistical tools for model validation, but the primary tool for most process modeling applications is graphical residual analysis. Different types of plots of the residuals (see definition below) from a FITTED model provide information on the adequacy of different aspects of the model. Numerical methods for model validation, such as the R2 statistic, are also useful, but usually to a lesser degree than graphical methods. Unfortunately, a high R2 (coefficient of determination) does not guarantee that the model fits the DATA well, because as Anscombe's quartet SHOWS, a high R2 can occur in the presence of misspecification of the functional form of a relationship or in the presence of outliers that DISTORT the true relationship. One problem with the R2 as a measure of model validity is that it can always be increased by adding more variables into the model, except in the unlikely event that the additional variables are EXACTLY uncorrelated with the dependent variable in the data sample being used. To avoid such spurious increases of the R2, one can instead use the adjusted R2, which penalizes the use of additional explanatory variables in accordance with the amount that they are likely to spuriously increase the R2.

14.	Does this figure have rotational symmetry?A) No, pentagons cannot be rotated. B) No, it has five lines of symmetry. C) Yes, it has five lines of symmetry. D) No, it only looks the same if it is rotated 360°. CORRECT ANSWER
Answer» Answer: D) No, it only looks the same if it is ROTATED 360°. Step-by-step explanation: We are GIVEN a pentagon with a solid circle at ONE of its CORNER. We know that a figure is said to has rotational symmetry if it appears exactly same after a rotation about particular degrees. The order of rotational symmetry is the number of times a SHAPE maps onto itself during a rotation of 360°. Generally the order of rotational symmetry of a pentagon is 5 as it maps onto itself during a rotation of 360°. But the given pentagon has a solid circle at one of its corner, because of this it only looks the same if it is rotated 360°. Therefore, the given figure do not has rotational symmetry.

Answer»

Answer: D) No, it only looks the same if it is ROTATED 360°.

Step-by-step explanation:

We are GIVEN a pentagon with a solid circle at ONE of its CORNER.

We know that a figure is said to has rotational symmetry if it appears exactly same after a rotation about particular degrees.

The order of rotational symmetry is the number of times a SHAPE maps onto itself during a rotation of 360°.

Generally the order of rotational symmetry of a pentagon is 5 as it maps onto itself during a rotation of 360°.

But the given pentagon has a solid circle at one of its corner, because of this it only looks the same if it is rotated 360°.

Therefore, the given figure do not has rotational symmetry.

28.

A is twice as old as B 5 year ago a was three times as old as B find their present ages

Answer»

LET the PRESENT ages of A and B be x and y respectively.

ATQ,

• x = 2y (equation 1)

• (x-5) = 3(y-5)

x - 5 = 3y - 15

x - 3y = -15 +5

2y - 3y = -10 (from equation 1)

-y = -10

y = 10

Put y=10 in equation 1,

x = 2(10)

x = 20

Hence present ages of A and B are 10 and 20 respectively.

Hope it HELPS!!! :)

A sum of money is borrowed and paid back in two equal installments

Answer»

"The general formulae for INSTALLMENTS in case of compound interest is P =x/(1+R/100) + x/(1+r/100)^2 ....x/(1+000)

And here we have to find P

Given x = 882 r = 5 and n=2

On substituting the values

We GET P =882/ (1+5/100) + 882/ (1+5/100) ^2 p = 882*20/21 + 882*400/441

P= 840 + 800 = 1640"

Based on inductive reasoning, if two lines meet at a 90 angle, then they have opposite reciprocal slopes.D. Based on inductive reasoning, if two lines have opposite reciprocal slopes, then they meet at a 90 angle.
Answer» ANSWER: A. Based on the law of syllogism, if two LINES MEET at a 90 angle, then they have opposite reciprocal slopes. Step-by-step explanation: Law of Syllogism which is also known as reasoning by transitivity is a VALID argument method of a deductive reasoning that follows a sequence. Its similar to the transitive property of equality, which states that if a=b and b=c then a=c The given statement : If two lines meet at a 90 angle, they are perpendicular. If two lines are perpendicular, they have opposite reciprocal slopes. let a →" two lines meet at a 90 angle" b→ "two lines are perpendicular are perpendicular" c→" two lines have opposite reciprocal slopes" Since a→b and b→c Therefore by law of syllogism, a→c Therefore by law of syllogism, a→ci.e. If two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Based on inductive reasoning, if two lines have opposite reciprocal slopes, then they meet at a 90 angle.

Answer»

ANSWER: A. Based on the law of syllogism, if two LINES MEET at a 90 angle, then they have opposite reciprocal slopes.

Step-by-step explanation:

Law of Syllogism which is also known as reasoning by transitivity is a VALID argument method of a deductive reasoning that follows a sequence.

Its similar to the transitive property of equality, which states that if a=b and b=c then a=c

The given statement : If two lines meet at a 90 angle, they are perpendicular. If two lines are perpendicular, they have opposite reciprocal slopes.

let a →" two lines meet at a 90 angle"

b→ "two lines are perpendicular are perpendicular"

c→" two lines have opposite reciprocal slopes"

Since a→b and b→c

Therefore by law of syllogism, a→c

Therefore by law of syllogism, a→ci.e. If two lines meet at a 90 angle, then they have opposite reciprocal slopes.
