Answer:

Let's break down the language first.

"8 less than" means minus 8 and should be put at the end of your mathematical statement. "the quotient" means division so we will be dividing "a number and ten"

I'm going to use the variable n for "a number"

n ÷ 10 - 8

n/10 - 8

Step-by-step explanation:

$\bf \sqrt{\cfrac{3}{16}}\cdot \sqrt{\cfrac{3}{9}}\implies \cfrac{\sqrt{3}}{\sqrt{16}}\cdot \cfrac{\sqrt{3}}{\sqrt{9}}\implies \cfrac{\sqrt{3}}{4}\cdot \cfrac{\sqrt{3}}{3}\implies \cfrac{\sqrt{3}\cdot \sqrt{3}}{4\cdot 3}
\\\\\\
\cfrac{(\sqrt{3})^2}{12}\implies \boxed{\cfrac{3}{12}}\implies \stackrel{simplified}{\cfrac{1}{4}}$

determine if the following triangles are similar, and if so which postulates or theorem proves they are similar

kari74 [83]

Not similar.

Because it should be $\frac{22}{11} =\frac{18}{9} \neq \frac{24}{13}$

2=2 $\neq$ 1.84

aisha used six boards on each of the birdhouses she made .which experssion represents the total number of boards she would need

insens350 [35]

Well normally you would have to know the amount of birdhouses that she made. But if not, then it would be multiplying 6 times the number of n the amount of birdhouses that she made. Not sure if this is making sense. but if there are 6 boards for N (each of the bird houses) then the answer would just be 6n which is 6 times n

Write the equation of the line that passes through the given point and has the given slope. (-4,1)

Olenka [21]

Answer:

$_{\text{point-slope form}}$

$\huge\boxed{y-1=-\dfrac{1}{4}(x+4)}$

$_{\text{slope-intercept form}}$

$\huge\boxed{y=-\dfrac{1}{4}x}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

where

$m$ - a slope

$(x_1 y_1)$ - a point of a line

We have

$m=-\dfrac{1}{4};\ (-4;\ 1)\to x_1=-4;\ y_1=1$

Substitute:

$y-1=-\dfrac{1}{4}(x-(-4))\\\\y-1=-\dfrac{1}{4}(x+4)$

=============================================

$y-1=-\dfrac{1}{4}(x+4)\qquad|\text{use the distributive property}\\\\y-1=-\dfrac{1}{4}x-1\qquad|\text{add 1 to both sides}\\\\y=-\dfrac{1}{4}x$

What is the difference between lcm and lcd??

Hunter-Best [27]

The lowest common denominator, or LCD, denotes the smallest number divisible by the denominators of every fraction in a set, whereas a least common multiple, orLCM, is the smallest multiple that two numbers have in common as products. Finding the LCD and LCMrequires knowing prime factors of a number.
