Answer: x= 5

Step-by-step explanation:

distribute the -2 into the parentheses then do the same for the 3 on the other side of the plus sign then combine like terms you end up with 6x-5=25 to undo that add the five to the 25 to get 6x=30 divide by 6 therefore you end up with x= 5

Since the scale factor is 4:3 then every dimension of triangle WXY is (3/4) of every dimension of triangle CDE.
The perimeter of triangle CDE = 13 + 22 + 29 = 64.
So, the perimeter of triangle WXY = (3/4) * 64 = 48

As the limit of x goes to 3 from the left find the limit of (x/ sqrt x^2 -9)

Dimas [21]

$\displaystyle\lim_{x\to3^-}\frac x{\sqrt{x^2-9}}=\lim_{x\to3^-}\frac x{\sqrt{x^2}\sqrt{1-\frac9{x^2}}}=\lim_{x\to3^-}\frac x{|x|\sqrt{1-\frac9{x^2}}}$

Since $x>0$ , you have $|x|=x$ and the limand reduces to

$\displaystyle\lim_{x\to3^-}\frac1{\sqrt{1-\frac9{x^2}}}$

For $x>3$ , you have $\sqrt{1-\frac9{x^2}}>0$ since $\dfrac9{x^2}$ will always be smaller than 1, which means $\dfrac1{\sqrt{1-\frac9{x^2}}}\to+\infty$

When renting a limo for prom, the number of people is inversely proportional to the cost per person. Originally there were 5 peo

Oksana_A [137]

Answer: The cost per person would be $15.20.

Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.

8,8 x 6 = 52,80.

44 x 5= 220,00. That was the cost for the limo for 5 people.

It means 220,00 - 52,80 = 167,20 (new price for 11 people)

167,20 ÷ 11 (new price per person) = 15,20.

What is the distance in meter of an object that has an angular diameter of 30 arcseconds and a linear diameter of 10 cm?

Leya [2.2K]

Answer:

Distance of object = 0.0144 meter

Step-by-step explanation:

Given:

Angular diameter = 30 arcseconds = 30[100 / 3600]

Length of diameter = 10 cm

Find:

Distance of object

Computation:

Distance of object = [(2)(a)][TanФ / 2]

Distance of object = [(2)(10)][Tan(300 / 7200]

Distance of object = [20][Tan 0.04167]

Distance of object = [20][0.00072]]

Distance of object = 0.0144 meter
