Rewrite 7.13 as a mixed number in lowest terms

bezimeni [28]

Hey there! I'm happy to help!

A mixed number is a whole number and a fraction. We already see that our whole number is 7.

Our decimal is 0.13. Since this goes into the hundredths place, we can rewrite this as 13/100. This cannot be simplified anymore.

Therefore, 7.13 is 7 13/100 in lowest terms.

Have a wonderful day! :D

A car traveling east at a constant rate of 33 mi/hr passes through an intersection at 10 A.M. A truck traveling north at a const

Rufina [12.5K]

Answer:52.33 m/s

Step-by-step explanation:

Given

Speed of car $v_1=33 mi/hr$

Speed of truck $v_2=42 mi/hr$

Distance traveled by car in 1 hr is 33 mi

Therefore after 11 am distance of car and truck from Junction in time t is

Car $=33+33t$

truck $=42 t$

Let D be the distance between them

$D^2=42t^2+(33+33t)^2$ ------------1

at $t= 2 hr$

$D^2=(42\times 2)^2+(33+66)^2$

$D=129.83 miles$

To get how fast distance between them is increasing differentiate 1 we get

$2D\frac{\mathrm{d} D}{\mathrm{d} t}=2\cdot(42)^2t+2\cdot 33^2(1+t)$

$\frac{\mathrm{d} D}{\mathrm{d} t}=\frac{42^2t+33^2\left ( 1+t\right )}{D}$

$\frac{\mathrm{d} D}{\mathrm{d} t}=\frac{1764\times 2+1089\times 3}{D}$

$\frac{\mathrm{d} D}{\mathrm{d} t}=\frac{6795}{129.83}=52.33 m/s$
