Answer: False.

Step-by-step explanation:

There does not exist a "quarter circle" as a circle with a radius of 4 units, the only notable circle that does exist is the unit circle, that is the circle where the radius is equal to 1, represented by the equatin x^2 + y^2 = 1

The term "quarter circle" actually does refer to a fourth part of a circle, not to a circle of radius 4.

So the statement is false

If two triangles are put together what is the name of the shape

Lostsunrise [7]

It depends on which triangles you put together, if they are equilateral triangles, then its a diamond, if they are rectangle (right) triangles, then its a rectangle, if they are isosceles triangles, then its a really sharp diamond, and if they are scalene triangles, then the shape is like a common kite.

When y is 4, p is 0.5, and m is 2, x is 2. If x varies directly with the product of p and m and inversely with y, which equation

Radda [10]

<h3><u>Question:</u></h3>

When y is 4, p is 0.5, and m is 2, x is 2. If x varies directly with the product of p and m and inversely with y, which equation models the situation?

xpmy=8

xy/pm=8

xpm/y=0.5

x/pmy=0.5

<h3><u>Answer:</u></h3>

The equation models the situation is $\frac{x y}{p m}=8$

<h3><u>Solution:</u></h3>

Given that

x is 2, y is 4, p is 0.5, and m is 2

x varies directly with the product of p and m

x varies inversely with y

$\text {Product of } p \text { and } m=p \times m=p m$

x varies directly with the product of p and m

$=>x \propto p m$ ---- eqn 1

As x varies inversely with y,

$=>x \propto \frac{1}{y}$ ----- eqn 2

From (1) and 2, we can say that

$x \propto \frac{p m}{y}$

$\Rightarrow x=k \frac{p m}{y}$

where k is constant of proportionality

$\Rightarrow \frac{x y}{p m}=k$ ---- eqn 3

On substituting given values of x = 2, y = 4, p = 0.5 and m= 2 in eqn (3) we get

$\frac{x y}{p m}=\frac{2 \times 4}{0.5 \times 2}=k$

$\begin{array}{l}{\frac{x y}{p m}=\frac{8}{1}=k} \\\\ {=>\frac{x y}{p m}=8}\end{array}$

Hence correct option is second that is $\frac{x y}{p m}=8$

Please show me the steps of 78.32/0.22

iragen [17]

Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

Let's first establish the problem as the following:

= 78.32 / 0.22

First, we will make the deniminator a whole number. In order to accomplish this, we will multiply both the numerator and denominator in the fraction by 100.

= ( 78.32 × 100 ) / ( 0.22 × 100 )

= 7832 / 22

Next we will divide both the numerator and denominator by the highest common factor ( HCF ) of the two numbers in order to simplify the fraction fully.

The highest common factor of 7832 and 22 is 22.

HCF = 22

This means that we will divide both the numerstor and denominator of the fraction by 22.

= ( 7832 ÷ 22 ) / ( 22 ÷ 22 )

= 356 / 1

= 356

FINAL ANSWER:

Therefore, the answer is: 356.

Hope this helps! :)
Have a lovely day! <3
