x/7 has to be proportionate to 9.2/16.1 so find out how 7 relates to 16.1

16.1/7=2.3 and 7*2.3=16.1

then apply it to x and 9.2

9.2/2.3= 4 and 4*2.3=9.2

So, x=4

Consider kite WXYZ. What are the values of a and b? a = 4; b = 10. a = 4; b = 40, a = 8; b = 10, a = 8; b = 40

Brut [27]

Check the picture below.

let's recall that a kite is a quadrilateral, and thus is a polygon with 4 sides

sum of all interior angles in a polygon

180(n - 2) n = number of sides

so for a quadrilateral that'd be 180( 4 - 2 ) = 360, thus

$\bf 3b+70+50+3b=360\implies 6b+120=360\implies 6b=240 \\\\\\ b=\cfrac{240}{6}\implies b=40 \\\\[-0.35em] ~\dotfill\\\\ \overline{XY}=\overline{YZ}\implies 3a-5=a+11\implies 2a-5=11 \\\\\\ 2a=16\implies a=\cfrac{16}{2}\implies a=8$

Answer:

If they are travelling in opposite directions, their total distance is the 135. So add their distances together to get 135

x=Quinn's speed

x+5 = James' speed

they each travel for 5 hours

speed x time = distance

x(5) + (x+5)(5) = 135

Quinn's distance + James' distance = total distance

5x+5x+25=135

10x = 110

x = 11

Quinn travels at 11 mph and James travels at 16 mph

Quinn travels 55 miles (5x11)

and James travels 80 miles (16 x 5)

80 + 55=135

elena-14-01-66 [18.8K]

Step 1

Nathaniel

Start time = t

Speed = 48

$\text{Distance = 48t}$

Step 2

Mikaela

$\begin{gathered} \text{Start time = t - 0.5} \\ \text{Speed = 72} \\ \text{Distance = 72(t - 0.5)} \end{gathered}$

Step 3

Equate the two distance

$\begin{gathered} 48t\text{ = 72(t - 0.5)} \\ 48t\text{ = 72t - 36} \\ 36\text{ = 72t - 48 t} \\ \text{36 = 24t} \\ \text{t = }\frac{36}{24} \\ \text{t = }\frac{3}{2}\text{ = 1}\frac{1}{2}\text{ hours} \end{gathered}$

Final answer

$It\text{ take( 1}\frac{1}{2}-\frac{1}{2})=1\text{ hours to catch up}$

Answer: 1 hour
