Acar is traveling down a highway at a constant speed, described by the equation d = 65t, where d represents the distance, in miles, that the car travels at this speed in t hours questions = a. what does the 65 tell us in this situation? b. how many miles does it take the car to travel 26 miles at this speed? c. how long does it take the car to travel 26 miles at this speed?

We are required to explain what 65 tell us in this situation

65 in situation is the speed of traveling

Given:

d = 65t

Recall the formula to calculate distance

d = s × t

where,

d = total distance travelled

s = speed

t = total time taken

Therefore, 65 in situation is the speed of traveling

d = 65t

26 miles = 65 × t

26 = 65t

t = 26/65

t = 0.4 hours

1 hour = 60 minutes

0.4 hour = 60 × 0.4

= 24 minutes

In conclusion, it takes 24 minutes for the car to travel 26 miles at this speed.

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,

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.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
