Kiley would need glass of area between 3.14 and 12.56 square feet

Step-by-step explanation:

The Circumference of the circle is given by 2πr where “r” is the radius

Range of the circle’s circumference- 6.28 feet to 12.56 feet

Considering lowest radius as r₁ and the largest as r₂

2πr₁= 6.28

∴r₁= 6.28/(3.14*2) = 1 feet

Similarly

⇒2πr₂=12.56/(3.14*2)=2 feet

We know that area of the circle is given by πr ²

Area of the circle= 3.14*(1)² = 3.14 square feet

Area of the largest radius= 3.14*(2)²= 12.56 square feet

Hence Kiley would need glass of area between 3.14 and 12.56 square feet

Write a linear equation in standard form that satisfies the given set of conditions. X-intercept: 3, y-intercept: 5
Artyom0805 [142]

The linear equation in standard form is y=\frac{-5}{3}x +5.

<h3>Linear Function</h3>

An equation can be represented by a linear function. The standard form for the linear equation is: ax+b , for example, y=7x+2. Where:

a= the slope. It can be calculated for  \frac{\Delta x }{\Delta y}.

b= the constant term that represents the y-intercept.

The question gives: X-intercept:3  and  y-intercept: 5. Then,

  • The x-intercept is the point that y=0, then the x-intercept point is (3,0).
  • The y-intercept is the point that x=0, then the x-intercept point is (0,5).

With this information, you can find the slope (a).

a=\frac{\Delta y }{\Delta x}= \frac{0-5}{3-0} =\frac{-5}{3}

The question gives the coefficient b since it gives the y-intercept=5.

Therefore the linear equation is : y=\frac{-5}{3}x +5.

Find the value of n:<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B11%7D%20%3D%20%5Cfrac%7B3.5%7D%7B7%7D" id="TexFormul

The value of n from the given expression is 5.5

<h3>Solution to linear equation and fractions</h3>

Fractions are expression written as a ratio of two integers. The linear equation on the other hand has a leading degree of 1.

Given the equation below;

n/11 = 3.5/7

Simplify to have

n/11 = 1/2

Cross multiply the given result to have:

11 = 2n

Swap

2n = 11

Divide both sides by 2 to have;

2n/2 = 11/2

n = 5.5

Hence the value of n from the given expression is 5.5
