Answer:

  1596 miles

Step-by-step explanation:

A suitable proportion can be ...

  \dfrac{\text{miles}}{\text{hours}}=\dfrac{M}{14\text{ h}}=\dfrac{342\text{ mi}}{3\text{ h}}\\\\M=\dfrac{14\cdot 342}{3}\text{ mi}=1596\text{ mi}

We solved it by multiplying both sides by 14 hours. The units of hours cancel, leaving units of miles.

Michelle's car can travel 1596 miles in 14 hours.

Divide the distance by the average speed to find the time. 30 miles 20.04 mph 1.497 hrs. So it would take about 1.5 hours.

Answer: Choice A) x = 15; y = 17

---------------------

Explanation:

The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15

We technically have enough to stop here, but let's keep going to find y

The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees

So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17

Answer:

CD = 2 units

Step-by-step explanation:

in the given right triangle ΔCDE,

By applying tangent rule,

tan(∠E) = \frac{\text{Opposite side}}{\text{Adjacent side}}

            = \frac{\text{CD}}{\text{DE}}

tan(30)° = \frac{\text{CD}}{2\sqrt{3}}

\frac{1}{\sqrt{3}}=\frac{\text{CD}}{2\sqrt{3}}

CD = \frac{2\sqrt{3}}{\sqrt{3}}

CD = 2 units

Therefore, CD = 2 unit will be the answer.
