Answer:

Step-by-step explanation:

perimeter=22

AB+BC+AC=22

8+5+AC=22

AC=22-13

AC=9

Apply the Pythagorean theorem:

AB²+AB²=AC²

8²+5²=64+25=89

AC²=9²=81

no it is not a right triangle because it failed the Pythagorean theorem

Give the following equations determine if the lines are parallel perpendicular or neither

GaryK [48]

In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.

Let's start with the first equation.

$\frac{6x-5y}{2}=x+1$

Cross multiply both sides of the equation.

$6x-5y=2(x+1)$ $6x-5y=2x+2$

Subtract 6x on both sides of the equation.

$6x-5y-6x=2x+2-6x$ $-5y=-4x+2$

Divide both sides of the equation by -5.

$-\frac{5y}{-5}=\frac{-4x}{-5}+\frac{2}{-5}$ $y=\frac{4}{5}x-\frac{2}{5}$

Therefore, the slope of the first equation is 4/5.

Let's now simplify the second equation.

$-4y-x=4x+5$

Add x on both sides of the equation.

$-4y-x+x=4x+5+x$ $-4y=5x+5$

Divide both sides of the equation by -4.

$\frac{-4y}{-4}=\frac{5x}{-4}+\frac{5}{-4}$ $y=-\frac{5}{4}x-\frac{5}{4}$

Therefore, the slope of the second equation is -5/4.

Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.

What is 168.023 in expanded form using fractions

bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$

Step-by-step explanation:

Expanded form:

Is a way to write numbers to see the math value of the digits.

When numbers are separated into their place values and decimal places they can also form a mathematical expression.

Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + $\frac{2}{10}$ + $\frac{7}{100}$ = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = $\frac{2}{100}$

∵ Its thousandths digit is 3

∴ Its value = $\frac{3}{1000}$

∴ The expanded form of 168.023 = 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$
