Becca hikes 9/10 mile in 3/5 hour. Which fraction represents Becca's speed in miles per hour? The answer choices are: 3/5 / 9/10

Answer:

Step-by-step breakdown:

Let c denote the quantity of child tickets sold.

Let a denote the quantity of adult tickets sold.

On Tuesday, the zoo sold a total of 250 admission tickets. This total consists of child tickets and adult tickets, resulting in the equation:

c + a = 250 - - - - - - - - - - 1

The cost for a child's ticket is $12.75, while an adult ticket costs $18.50. The total ticket sales amounting to $4739.50 indicates that:

12.75c + 18.5a = 4739.50 - - - - - - - 2

Equations 1 and 2 form the system necessary to find the number of adult tickets, a, and child tickets, c, sold.

To isolate C in the equation

start by subtracting P from both sides:

Then, add C to both sides to get:

The equation that represents the quantity of quarters, q, and dimes, d, in Austin's piggy bank is standardized as 5q + 2d = 270. This can be altered to slope-intercept form for clarity. By dividing every term by 2, the equation transforms to d = -2.5q + 135. This indicates that Austin starts with 135 dimes in his piggy bank and is losing 2.5 dimes for each quarter he has.

Response:

Detailed explanation:

The spinner has four colors: red, blue, green, and yellow. Joaquin spins this spinner two times. The possible outcomes are represented as

S = {RB, RG, RY, RR, BR, BG, BY, BB, GR, GB, GY, GG, YR, YB, YG, YY}.

Considering the variable “yellow (Y),” let’s determine the potential values for Y.

From the aforementioned set, it appears that Y can assume only three values: 0, 1, or 2.

Within the 16 possible outcomes, Y appears 0 times in 9 instances, 1 time in 6 instances, and 2 times in 1 instance.

Therefore, the probability is calculated as the number of favorable outcomes divided by the total outcomes in the sample space.

This means

P(Y=0) = 9/16

P(Y=1) = 6/16 = 3/8

P(Y=2) = 1/16

The water contains no larvae at temperatures of -10 degrees Celsius and 20 degrees Celsius.
