Answer:

The number of nickles in drawer is 20 and

The number of dimes in drawer is 10

Step-by-step explanation:

Given as :

Total money in nickels and dimes = $ 2

Let The number of nickels = n

And The number of dimes = d

According to question

The number of nickels is three times number of dimes

I.e n = 3 times d

Or , n = 3 d

∵ n + d = $ 2

and 20 nickles = 1 dollar

10 dimes = 1 dollar

So, 20 nickles + 10 dimes = $ 1 + $ 1

or, 20 nickles + 10 dimes = $ 2

So, number of nickles is 20, and number of dimes is 10

Hence The number of nickles in drawer is 20 and

The number of dimes in drawer is 10 answer

Area of a Circle

Cloud [144]

Answer:

The diameter of the pond is 38 m.

The radius of the pond is 19 m.

The area of the pond is 361 m^2.

Step-by-step explanation:

We know that the circumference C of a circle is equal to

$C=\pi D$

In this case, C is equal to 120 m.

The diameter is then:

$D=C/\pi=120/3.14=38.21\approx 38$

Rounded to the nearest whole number, the diameter is D=38 metres.

The radius is equal to half the diameter, so the radius of this pond is R=19 metres.

$R=D/2=38/2=19$

The area can be calculated from the radius as:

$A=r^2=19^2=361$

The area is 361 m^2

Q5:

$\frac{\sqrt{3x^2y^3}}{4\sqrt{5xy^3}}$

$\frac{\sqrt{3}xy\sqrt{y}}{4\sqrt{5}y\sqrt{x}\sqrt{y}}$

Cancel off $\sqrt{x}$ :

$\frac{\sqrt{3}y\sqrt{x}\sqrt{y}}{4\sqrt{5}y\sqrt{y}}$

Cancel off $y:$

$\frac{\sqrt{3}\sqrt{x}\sqrt{y}}{4\sqrt{5}\sqrt{y}}$

Cancel off $\sqrt{y} :$

$\frac{\sqrt{3}\sqrt{x}}{4\sqrt{5}}$

Multiply $\sqrt{5}$ on the numerator and denominator:

$\frac{\sqrt{3}\sqrt{x}\sqrt{5}}{4\sqrt{5}\sqrt{5}}$

$\frac{\sqrt{15}\sqrt{x}}{20}$
