so what they mean by "similar" is just that the shapes are the same but different sizes. since we have the measurement for sides PM, MN and TQ, we can figure it out. we have to think of it as a ratio. so PM/TQ = MN/QR. if we plug the amounts in its 57/23 = 40.3/QR. then we cross multiply. so thats 23 x 40.3 which is 926.9. then we divide 926.9 by 57 which is 16.2614035. rounding to the nearest tenth is 16.3

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of g
kirill115 [55]

Answer:

5 gallons

Step-by-step explanation:

We can use ratios to solve

5/12 gallon        x gallons

----------------  = -------------------

1/24 minute       1/2 minute

Using cross products

5/12 * 1/2 = x *1/24

5/24 = x/24

Multiply each side by 24

24*5/24 = x/24*24

5=x

We can pump 5 gallons

A ball is thrown from an initial height of 3 meters with an initial upward velocity of 30 m/s. The ball's height h (in meters) a
yanalaym [24]

h=3+30t-5t^2\implies 13=3+30t-5t^2\implies 0=-10+30t-5t^2 \\\\\\ 5t^2-30t+10=0\implies 5(t^2-6t+2)=0\implies t^2-6t+2=0

now, it doesn't give us nice looking integers, so let's plug that into the quadratic formula.

~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{1}t^2\stackrel{\stackrel{b}{\downarrow }}{-6}t\stackrel{\stackrel{c}{\downarrow }}{+2}=0 ~\hspace{10em} t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ t= \cfrac{ - (-6) \pm \sqrt { (-6)^2 -4(1)(2)}}{2(1)}\implies t=\cfrac{6\pm\sqrt{36-8}}{2}

t=\cfrac{6\pm\sqrt{28}}{2}\implies t=\cfrac{6\pm\sqrt{2^2\cdot 7}}{2}\implies t=\cfrac{6\pm 2\sqrt{7}}{2}\implies t=\cfrac{2(3\pm 1\sqrt{7})}{2} \\\\\\ t=3\pm \sqrt{7}\implies t= \begin{cases} 3+\sqrt{7}\\ 3-\sqrt{7} \end{cases}\implies t\approx \begin{cases} 5.65\\ 0.35 \end{cases}

All sides of a regular pentagon have the same length

1 side = 4

4x5 = 20 = Perimeter

Pentagon area formula :

1/4(sqrt(5(5+2sqrt(5)))x)

Plug x in (side length)

27.53

round to nearest tenth

elena55 [62]
Siamone has $65.32 + DAN 
Dan has CARLY - $37.50
CARLY = $127.75 
Plug Carly into Dan's equation... 
$127.75 - $37.50 = $90.20
DAN = $90.20
Plug Dan into Siamone's equation
$65.32 + $90.20 = $155.57
