Answer:

The rate of interest is6.4 %

Step-by-step explanation:

Given : Principal (P) = Rs12500

Total amount (A) = Rs16500.

The time period (t) =5 years

To find : Rate of interest (R) = ?

Solution :

It is given that Principal (P) = Rs. 12500

Total amount (A) = Rs. 16500

The time period (t) =5 years

We have to find rate of interest (R).

We know the formula for simple interest as,

S.I. = A-P

= 16500±12500

= Rs. 4000

Now, to find rate of interest, use the formula for simple interest as

S.I. =

∴

∴ *R

∴

∴R=6.4 %

∴ The rate of interest is6.4 %.

Which expression represents the correct form for the quotient and remainder, written as partial fractions, of StartFraction 6 x

diamong [38]

Answer:

The answer is "quotient =2x+5 and remainder =6x+1".

Step-by-step explanation:

Some of the data is missing that's why defined this question as follows:

Given:

$\to \frac{6x^3+15x^2+20x+36} {3x^2+7}$

when we divide the above value it will give the quotient =2x+5 and remainder =6x+1.

Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

1. Given the expression

$\dfrac{\sqrt[7]{x^5} }{\sqrt[4]{x^2} }$

Note that

$\sqrt[7]{x^5}=x^{\frac{5}{7}} \\ \\\sqrt[4]{x^2}=x^{\frac{2}{4}}=x^{\frac{1}{2}}$

When dividing $\sqrt[7]{x^5}$ by $\sqrt[4]{x^2},$ we have to subtract powers (we cannot subtract 4 from 7, because then we get another expression), so

$\dfrac{5}{7}-\dfrac{2}{4}=\dfrac{5}{7}-\dfrac{1}{2}=\dfrac{5\cdot 2-1\cdot 7}{14}=\dfrac{3}{14}$

and the result is $x^{\frac{3}{14}}=\sqrt[14]{x^3}$

2. Given equation $3\sqrt[4]{(x-2)^3} -4=20$

Add 4:

$3\sqrt[4]{(x-2)^3} -4+4=20+4\\ \\3\sqrt[4]{(x-2)^3}=24$

Divide by 3:

$\sqrt[4]{(x-2)^3} =8$

Rewrite the equation as:

$(x-2)^{\frac{3}{4}}=8\\ \\(x-2)^{\frac{3}{4}}=2^3$

Hence,

$\left((x-2)^{\frac{3}{4}}\right)^{\frac{4}{3}}=(2^3)^{\frac{4}{3}}\\ \\x-2=2^{3\cdot \frac{4}{3}}\\ \\x-2=2^4\\ \\x-2=16\\ \\x-2+2=16+2\\ \\x=18$

Find x, y, z, so that 41, 46, x, y, z has a mean of 50 and a mode of 45

nevsk [136]

Answer:

Step-by-step explanation:

as mode is 45 ,two of three is 45

i assume x =y=45

now (41+46+45+45+z)/5=50

177+z=50×5=250

z=250-177=73

so x=45

y=45

z=73
