A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile

Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where d represents the distance, that the car travels at this speed in t at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

PLEASE HELP ME!<br> Find m∠FEC.<br><br> Answer Options:<br> A. 69<br> B. 50<br> C. 57<br> D. 37

Anna35 [415]

Answer:

Option (A)

Step-by-step explanation:

Measure of an angle formed between a chord and a secant is equal to the half of the difference of the intercepted arcs.

m(∠FEC) = $\frac{1}{2}[m(\text{arc FC})-m(\text{arc})FD]$

(15 + 6x)° = $\frac{1}{2}[(24x - 6)^{\circ}-(9+7x)^{\circ}]$

30 + 12x = (24x - 7x) - (6 + 9)

30 + 12x = 17x - 15

17x - 12x = 30 + 15

5x = 45

x = 9

m(∠FED) = (15 + 6x)

= 15 + 6(9)

= 69°

Option (A) will be the correct option.
