Hello ! I'm happy to help
the answer all revolves around this simple formula:
speed= distance/time
since you were driving for 1/4 of an hour that's 15 minutes
and we already know that you traveled 15 miles
so the speed would equal 15 miles every 15 minutes
if you want to find the total distance travelled is 15x15 =225

For a resistor in a direct current circuit that does not vary its resistance, the power that a resistor must dissipate is direct

Mrrafil [7]

THe problem is basically telling us: $P=kV^2$

where P is the power disappated and V^2 is our voltage squared.

$\frac{1}{16}=k*14^2\implies\\ \frac{1}{16*196}=k \implies \\ \frac{1}{3136}=k$

So, for the second example to find the power we simply have to plug k and our voltage back in, so: $P=\frac{14^2*3^2}{14^2*6} \implies \\ P=\frac{9}{6}= \frac{3}{2}$

Answer:

$\displaystyle 79°$

Step-by-step explanation:

The m∠x is 79°, according to the Alternate Exterior Angles Theorem.

I am joyous to assist you anytime.

* That does NOT look like an acute angle because 79° is considered an acute angle, since it is less than 90°.
