A shopkeeper bought a chair for RS 75 and sold it for rs100 find the gain percentage

40 POINTS AVAILABLE!!! PLEASE HELP

NemiM [27]

Step-by-step explanation:

$\begin{array}{ccc}1&-&d\\2&-&c\\3&-&a\\4&-&b\\5&-&f\\6&-&e\end{array}$

Value 1:

r = 5ft, h = 10ft. Substitute:

$SA=2\pi(5)(10)+2\pi(5^2)=100\pi+50\pi=150\pi\ ft^2$

Value 2:

r = 2in, h = 4in. Substitute:

$V=\dfrac{1}{3}\pi(2^2)(4)=\dfrac{1}{3}\pi(4)(4)=\dfrac{16\pi}{3}\\\\\pi\approzx3.14\to V\approx\dfrac{(16)(3.14)}{3}\approx16.75\ in^3$

Value 3:

r = 6m. Substitute:

$V=\dfrac{4}{3}\pi(6^3)=\dfrac{4}{3}\pi(216)=4\pi(72)=288\pi\ m^3\\\\\pi\approx3.14\to V\approx288(3.14)=904.32\ m^3$

There are 107 coins in a jar, all dimes and nickels. The coins are worth $6.70. How many of each kind of

weqwewe [10]

d = number of dimes

n = number of nickels

The jar contains a total of 107 coins, so

d + n = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10d + 0.05n = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10d + 5n = 670

Multiply both sides of the first equation by -5:

-5d - 5n = -535

Add the corresponding sides of these two equations to eliminate n and solve for d :

(10d + 5n) + (-5d - 5n) = 670 + (-535)

(10 - 5)d + (5 - 5)n = 670 - 535

5d = 135

d = 135/5 = 27

Then

n = 107 - d = 80

so the jar contains 27 dimes and 80 nickels.

If a 6 mile race is divided into 1 3 of a mile sections, how many sections are there in the race?

arlik [135]

Hey there!

Here is your answer:

The proper answer to this question is "18 sections".

Reason:

Divide 6 and 1/3

6×3=18
1×1=1

18/1=18

Therefore it would be divided into 18 different sections.

If you need anymore help feel free to ask me!

Hope this helps!

Write the sum using summation notation, assuming the suggested pattern continues. -9 - 4 + 1 + 6 + ... + 66

Darya [45]

Answer:

$\sum\limits^n_{k=1} {(-14+5k)}$

Step-by-step explanation:

The series is an arithmetic series with first term (a1) -9 and common difference (d) 5. Then the general term (an) is ...

an = a1 +d(n-1) = -9 +5(n-1) = -14 +5n

The summation notation indicates the sum of "n" of these terms.
