1.	Find 3 rational no between -7/2 and-2
Answer» Given: $\frac{ - 7}{<klux>2</klux>} \: and \: - 2$ To find: 3 rational number between them Solution: At FIRST we will make the denominator of -2 equal to that of -7/2 $\frac{ - 2 \times 2}{1 \times 2} = \frac{ - 4}{2}$ Now, $\frac{ - 7}{2} \: and \frac{ - 4}{2}$ we have $\frac{ - 7 \times 2}{2 \times 2} = \frac{ - 14}{4} \\ \\ \frac{ - 4 \times 2}{2 \times 2} = \frac{ - 8}{4}$ Hence, 3 rational numbers between -2 and -7/2 are -13/2 , -12/2 , -11/2 You can also TAKE any other number in PLACE of 2 according to the values.

1.

Find 3 rational no between -7/2 and-2

Answer»

Given:

$\frac{ - 7}{<klux>2</klux>} \: and \: - 2$

To find:

3 rational number between them

Solution:

At FIRST we will make the denominator of -2 equal to that of -7/2

$\frac{ - 2 \times 2}{1 \times 2} = \frac{ - 4}{2}$

Now,

$\frac{ - 7}{2} \: and \frac{ - 4}{2}$

we have

$\frac{ - 7 \times 2}{2 \times 2} = \frac{ - 14}{4} \\ \\ \frac{ - 4 \times 2}{2 \times 2} = \frac{ - 8}{4}$

Hence, 3 rational numbers between -2 and -7/2 are

-13/2 , -12/2 , -11/2

You can also TAKE any other number in PLACE of 2 according to the values.

Find the simple intrest payable on a loan of N$ 6500 at 13.25% p.a at the end of fifty four months

Answer»

<P>Answer:

3875.63

Step-by-step explanation:

If P denotes the principal ($), R denotes the rate (percentage p.a.) and T denotes TIME (years), then:-

Given,

P = $ 6500,

R = 13.25% p.a.

T = 54 MONTHS = 4 years 6 months = 54/12 years = 9/2 years

S.I = (P × R × T)/100

= (6500 * 13.25 * 9) / 100*2

= 775125/200

Plzz ans this as quick as possible

Answer»

we know that

${\sin} {}^{2} ( \alpha ) + { \cos} {}^{2} ( \alpha ) = 1$

so

${\cos} {}^{2} ( \alpha ) = 1 - { \sin} {}^{2} ( \alpha )$

$but \: we \: have \: sin \alpha = \sin(q) \\ more \: appropritel \sin( \alpha ) = a \div b$

THEREFORE

${ \sin(q) } {}^{2} = (a \div b) {}^{2}$

$\cos( = \alpha ) = \cos(q)$

${\cos(q) } {}^{2} = 1 - a {}^{2} \div b {}^{2}$

$we \: have \: \\ \cos(q) = \sqrt{b {}^{2} - a {}^{2} \div b {}^{2} }$

therefore OPTION C should have been CORRECT but it is having a little blunder

a sum is distributed between a b and c in the ratio of 9:6:11.if A gives 500 feom his share to C then the ratio of the share of A b and c become 4:6:11

Answer»

Answer:

3545.45 ......... IND.

step by step EXPLANATION:

LET intial constant ratio be 'x'

sum = 9x + 6x + 11x = 26x

total sum will remain same in both cases as they EXCHANGED 500 between 2 of them .

final Shares with A = 4/21 *26x = 104x/21

& C = 11/21 *26x = 286x/21

(9x - 500)/(11x + 500) = 104/286

1430x = 195000 => x = 195000/1430

sum = 26 × 195000/1430 = Rs 3545.45

For what value of x, the mean of the given observations 2x – 5, x + 3, 7 – x, 5 – x andx + 9 with frequencies 2, 3, 4, 6 and 1 respectively is 4.

Answer»

ANSWER:

Step-by-step explanation:

Value of x = 1.

Step-by-step explanation:

We are given the following data below;

X frequency (f) X*f

2*x - 5 2 4*x - 10

x + 3 3 3*x + 9

7 - x 4 28 - 4*x

5 - x 6 30 - 6*x

x + 9 1 x + 9

Here, ∑f = 2 + 3 + 4 + 6 + 1 = 16

∑X*f = 4*x - 10 + 3*x + 9 + 28 - 4*x + 30 - 6*x + x + 9 = 66 - 2*x

Now, Mean of data, X BAR =

4 =

64 = 66 - 2*x

2*x = 66 - 64

x = 2/2 = 1

Therefore, value of x is 1.

For what value of y is 3 (y-1) + 7=40?

Answer»

Answer:

y = 12

Step-by-step explanation:

3(y-1) + 7 = 40

Multiply 3 with (y-1)

3y - 3 + 7 = 40

Solve the constants

3y + 4 = 40

LEAVE variable in the Left side and take constant in the Right side

3y = 40 - 4

3y = 36

y = 36/3

y = 12
