Answer:

24 km/hr

Step-by-step explanation:

Speed is the rate of distance traveled in a defined time. Average speed is to take calculate the total distance travel at different speeds dividing by the total time taken.

Total Time = 4 hours

Total Distance = 68 km + 3 km + 25 km = 96 km

Average Speed = Total Distance / Total Time taken= 96 km / 4 hours

Average Speed = 24 km per hour

Kayleigh babysat for 11 hours this week that was 5 fewer than 2/3 as manyas she baby sat last week, h write an equation to repre
mars1129 [50]

Answer:

10.5 hours

Step-by-step explanation:

To find the number of hours she babysat last week subtract 5 from 11 which is 7 hours. 7 hours is equal to 2/3 of the many hours. If she babysat h hours last week then solve for h using 2/3 h = 7.

Solve the equation by multiplying each side by the reciprocal.

3/2 * 2/3h = 7*3/2

h = 21/2

h = 10.5 hours

Who can help me with this
Lady bird [3.3K]

Answer:

Growth

Step-by-step explanation:

Given

\frac{2}{3}(2.5)^x

Required

Growth or decay

The general form is:

y = ab^x

Such that:

b = rate

For b, we have the following conditions:

b > 1 ----- Growth

0 --- Decay

b = 1 ---- None

Compare \frac{2}{3}(2.5)^x to y = ab^x

b = 2.5

<em>Because 2.5 > 1, then the first condition applies (growth)</em>

Alona [7]
Earl's expression is correct because if you sold 6 times more (multiplication) the opposite would be division.

If 1,456 regular tickets is 6 times more than discount tickets than the number of discount tickets is the number of regular tickets divided by 6. (1,456÷6)
