Why is 6/8 greater than 5/8 but less that 7/8

1 answer:

6 0

Why 6/8 is greater than 5/8 is because 6/8 would be after 5/8. Its just "greater"! Why it's less than 7/8 is because it's not pass 7/8. Ex: 5 or 6. Which is greater? Would be 6 right. Same thing! Hope I helped!

Matilda is planning a walk around the perimeter of wedge park, which is shaped like a circular wedge, as shown below. the walk a

alukav5142 [94]

The area of the circular sector is
$A=\frac{1}{2}r^{2}\theta$

From that, the equation for the central angle is
$\theta=\dfrac{2A}{r^{2}}$

The perimeter of the circular sector is the sum of the arc length and twice the radius.
$P=2r+r\theta\\\\P=r(2+\theta)$

From that, the equation for the central angle is
$\dfrac{P}{r}=2+\theta\\\\ \theta=\dfrac{P}{r}-2$

The value of r can be found by equating these two expressions for θ.
$\dfrac{2A}{r^{2}}=\dfrac{P}{r}-2\\\\2r^{2}-Pr+2A=0\\\\2r^{2}-2.9r+0.5=0$

By any of several means, you can find that r=0.2 or 1.25. The latter value corresponds to the requirement that the central angle be less than 90°. The radius is ...
1.25 miles.

What is the slope of the line on this graph between 10 and 20 seconds?

Irina18 [472]

Answer:

3m/s

Step-by-step explanation:

delta y = 40m - 10m = 30m

delta x = 20s - 10s = 10s

slope = delta y / deltax = 30m / 10s = 3m/s

Answer:

$x=\frac{15}{4}=3\frac{3}{4}$

Equation:

$\frac{2}{3}x+\frac{5}{6} =\frac{10}{3}$

<h3>Step-by-step solution</h3>

Linear equations with one unknown

_____________________________________

1. Group all constants on the right side of the equation

$\frac{2}{3}\cdot x+\frac{5}{6}=\frac{10}{3}$

Subtract $5/6$ from both sides:

$\frac{2}{3}x+\frac{5}{6}-\frac{5}{6}=\frac{10}{3}-\frac{5}{6}$

Combine the fractions:

$\frac{2}{3}\cdot x+\frac{5-5}{6}=\frac{10}{3}-\frac{5}{6}$

Combine the numerators:

$\frac{2}{3}\cdot x+\frac{0}{6}=\frac{10}{3}-\frac{5}{6}$

Reduce the zero numerator:

$\frac{2}{3}\cdot x+0=\frac{10}{3}-\frac{5}{6}$

Simplify the arithmetic:

$\frac{2}{3}\cdot x=\frac{10}{3}-\frac{5}{6}$

Find the lowest common denominator:

$\frac{2}{3}\cdot x=\frac{10\cdot 2}{3\cdot 2}+\frac{-5}{6}$

Multiply the denominators:

$\frac{2}{3}\cdot x=\frac{10\cdot 2}{6}+\frac{-5}{6}$

Multiply the numerators:

$\frac{2}{3}\cdot x=\frac{20}{6}+\frac{-5}{6}$

Combine the fractions:

$\frac{2}{3}\cdot x=\frac{20-5}{6}$

Combine the numerators:

$\frac{2}{3}\cdot x=\frac{15}{6}$

Find the greatest common factor of the numerator and denominator:

$\frac{2}{3}\cdot x=\frac{5\cdot 3}{2\cdot 3}$

Factor out and cancel the greatest common factor:

$\frac{2}{3}\cdot x=\frac{5}{2}$

2. Isolate the x

$\frac{2}{3}\cdot x=\frac{5}{2}$

Multiply both sides by inverse fraction 3/2:

$\frac{2}{3}x\cdot \frac{3}{2}=\frac{5}{2}\cdot \frac{3}{2}$

Group like terms:

$\frac{2}{3}\cdot \frac{3}{2}x=\frac{5}{2}\cdot \frac{3}{2}$

Simplify the fraction:

$x=\frac{5}{2}\cdot \frac{3}{2}$

Multiply the fractions:

$x=\frac{5\cdot 3}{2\cdot 2}$

Simplify the arithmetic:

$x=\frac{15}{2\cdot 2}$

Simplify the arithmetic:

$x=\frac{15}{4}$

Why learn this

Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?

Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.
