If d is the number of degree and G is the number of grades of the same angle prove that D/9=G/10 |
|
Answer» Step-by-step explanation: The angle be C D degreesor G grades As π radian is EQUAL to 180 ∘ and 200 g
D degrees is D 180 × π radians i.e. C = D 180 × π or D π = 180 C
and similarly G grade is G 200 × π radians i.e. C = G 200 × π or G π = 200 C
Hence ( G − D ) π = 20 C |

A sum of money amounts to Rs. 1500 after 3 years and Rs. 2000 after 5 years at the same rate of SI. Find the rate of interest per annum ? |
|
Answer» Let assume that SUM of money invested be Rs P at the rate of r % per annum. We know, Simple interest (SI) on a certain sum of money of Rs P invested at the rate of r % per annum for n years is always same for every year and is given by and Now, ACCORDING to statement it is given that Amount on a certain sum of money is Rs 1500 after 3 years. Let assume that simple interest for 1 year on Rs P at the rate of r % per annum is SI. So, and Further it is given that Amount on certain sum of money is Rs 2000 after 5 years. So, On Subtracting equation (1) from equation (2), we get On SUBSTITUTING the value of SI in equation (1) we get Now, we have Simple Interest for 1 year = Rs 250 Sum of money invested, P = Rs 750 Time, n = 1 year We know, On substituting the values, we get Additional Information :-1. Amount on a certain sum of money of Rs P invested at the rate of r % per annum for n years compounded annually is 2. Amount on a certain sum of money of Rs P invested at the rate of r % per annum for n years compounded semi - annually is 3. Amount on a certain sum of money of Rs P invested at the rate of r % per annum for n years compounded quarterly is |

Prove that:sec⁶A - tan⁶A = 1 + 3 tan²A + 3 tan⁴A |
|
Answer» We have to prove: → sec⁶A - tan⁶A = 1 + 3 tan²A + 3 tan⁴A Taking LHS, we get: = sec⁶A - tan⁶A = (sec²A)³ - (tan²A)³ Using identity a³ - b³ = (a - b)³ + 3ab(a - b), we get: = (sec²A - tan²A)³ + 3 × sec²A × tan²A(sec²A - tan²A) We know that: → sec²θ - tan²θ = 1 Therefore, we get: = 1³ + 3 × sec²A × tan²A = 1 + 3 × (1 + tan²A) × tan²A [sec²θ = 1 + tan²θ] = 1 + 3 × (tan²A + tan⁴A) = 1 + 3 tan²A + 3 tan⁴A = RHS (HENCE Proved) 1.

Renu completed23part of her homework in 2 hours. How much part of her homework had shecompleted in 11⁄4 hours? |
|
Answer» Answer: 5/4 Step-by-step explanation: RENU completed 2/3 PART of her home work in 2 hours. Let us assume TOTAL part of homework be ‘P’. Then, 2/3 of P = 2 2/3 × P = 2 By cross MULTIPLICATION we get, P = 2 × 3/2 P = 3 home work So, part of her home work had she completed in 1¼ hours i.e. 5/4 hours |

What is 37 1\2% of 64? With explanation |
|
Answer» Answer: this your answer mate Step-by-step explanation: “percentage” is a fraction: “per CENT” means the denominator is one hundred (100). The numerator of this fraction is 37 + 1/2, which is 37.5, so just do the following: write the numerator: 37 + 12 or 37.5 draw a LINE underneath what you have written underneath the line, write a one (1) then a zero (0) and another zero (0) Now, you should SEE the following: 3712100 or: 37.5100 If you want the numerator to be a whole number, just multiply it by ten by moving the decimal point one place to the right (and then eliminating it because a decimal point is optional if nothing follows it); since you’ve multiplied the to by ten, you must do the same to the bottom: 3751000 Each of the above fractions is a correct answer to the question, but that last one is probably the one you want. |

Convert signed binary two's complement numbers to decimal system (base ten) integers Entered binary number length must be: 2, 4, 8, 16, 32, or 64 - otherwise extra bits on 0 will be added in front (to the left). Length, automatically calculated Signed binary two's complement (max. 64 bits): 11010101 Convert to integer How to convert a signed binary number in two's complement representation to an integer in base ten: 1) In a signed binary two's complement, first bit (leftmost) indicates the sign, 1 = negative, 0 = positive. 2) Get the signed binary representation in one's complement, subtract 1 from the initial number. 3) Construct the unsigned binary number: flip all the bits in the signed binary one's complement representation (reversing the digits) - replace the bits set on 1 with 0s and the bits on 0 with 1s. 4) Multiply each bit of the binary number by its corresponding power of 2 that its place value represents. 5) Add all the terms up to get the positive integer number in base ten. 6) Adjust the sign of the integer number by the first bit of the initial binary number.

The first bit is 1, so our number is negative. Get the signed binary representation in one's complement, subtract 1 from the initial number: 1101 1110 - 1 = 1101 1101
Get the binary representation of the positive number, flip all the bits in the signed binary one's complement representation (reversing the digits) - replace the bits set on 1 with 0s and the bits on 0 with 1s: !(1101 1101) = 0010 0010 Write bellow the positive binary number representation in base two, and above each bit that makes up the binary number write the corresponding power of 2 (numeral base) that its place value represents, starting with zero, from the right of the number (rightmost bit), walking to the left of the number, increasing each corresonding power of 2 by EXACTLY one unit: powers of 2: 7 6 5 4 3 2 1 0 digits: 0 0 1 0 0 0 1 0 Build the representation of the positive number in base 10, by taking each digit of the binary number, multiplying it by the corresponding power of 2 and then adding all the terms up: 0010 0010(2) = (0 × 27 + 0 × 26 + 1 × 25 + 0 × 24 + 0 × 23 + 0 × 22 + 1 × 21 + 0 × 20)(10) = (0 + 0 + 32 + 0 + 0 + 0 + 2 + 0)(10) = (32 + 2)(10) = 34(10) Signed binary number in two's complement representation, 1101 1110 = -34(10), a signed negative integer in base 10 aboutsuggestionstermscookie policy© 2016 - 2021 binary-system.base-conversion.roBinary base conversionAdd, subtract, round offPercentages calculatorsVAT calculatorSales taxSimple flat RATE interestsPrime factorsFractions operationsRoman numeralsNumbers to words converterLeap yearshaios.ro :-)Boys children namesWeb directory |
