To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $59 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for t.

Answer:

It is the last answer shown where the absolute value of -4 is the greatest

-2.47, -2, -1 3/4, -3/8, | -4 |

Step-by-step explanation:

Absolute value indicates how far away a value is from zero.  The sign is not relevant in that context.

The inches below average was the precipitation for both March and April is 6 1/4 inches

From the information given, the precipitation for the month of March was 4 3/4 inches less than average. In April, the precipitation was 1 1/2 inches less than average.

Therefore, the inches below average will be:

= 4 3/4 + 1 1/2

= 4 3/4 + 1 2/4

= 6 1/4

The inches is 6 1/4 inches.

Answer:

Step-by-step explanation:

In the counting of numbers from 2 to 99, the digit 9 appears 20 times.

To identify how many times the digit 9 appears, we can first list the numbers we know have a 9 in them:

9, 19, 29, 39, 49, 59, 69, 79, 89, 99

Although we've identified these numbers, we are not finished. Numbers in the 90s also qualify as digits of 9. Therefore, these numbers also are included:

91, 92, 93, 94, 95, 96, 97, 98

Now that we have all the numbers from 1 to 99 with the digit 9 in them, we can count up how many numbers there are with consideration that the number 99 also has two digits of 9 in it:

[(10 + 8) + 2] = 20

Hence, the digit 9 appears 20 times in the counting numbers from 1 to 99.

Answer:

There are 20 times the digit 9 appears in counting numbers from 1 to 99.

Step-by-step explanation:

To see why this is the case, we can break the counting numbers down into two categories: numbers with a 9 in the units place and numbers without a 9 in the units place.

For the first category, we can count the number of times a 9 appears in the units place by counting from 9 to 99 in increments of 10. There are 10 numbers in this category.

For the second category, we can count the number of times a 9 appears in the tens place by counting from 19 to 99 in increments of 100. There are 10 numbers in this category as well.

Therefore, the total number of times the digit 9 appears in counting numbers from 1 to 99 is 20 times.

If the Sharks had 16 swim meets in all, they won 10 swims.

Given,

Regan swims for the Sharks swim team. Last season, the Sharks won 5 swim meets for every 3 they lost.

We need to find out if the Sharks had 16 swim meets in all, and how many did they win.

Example:

2 cups = 4 eggs

To find for 4 cups.

We need to multiply 2 so that 2 cups becomes 4 cups.

4 cups = 2 x 4 eggs = 8 eggs

We have,

5 sims own for every 3 swims lost.

We can write it as:

5 own = 3 lost

Multiply 2 on both sides

2 x 5 own = 2 x 3 lost

10 own = 6 lost

We have,

16 swims in total.

It can be written as,

10 own = 6 lost

And we see that,

10 + 6 = 16 swims

Thus,

If the Sharks had 16 swim meets in all, they won 10 swims.

Reason:

If we were asked to compute log(ab), then we could use this log rule

log(ab) = log(a) + log(b)

However, we aren't multiplying the 'a' and b, so we cannot use the log rule above. There's not enough information to be able to compute log(a+b)

Choice C is a trick answer I've seen many students fall for since the erroneous thinking would be log(a+b) = log(a)+log(b) = 1.2+5.6 = 6.8

Answer:

  b) Not enough information

Step-by-step explanation:

Given the logs of two values, you want to know the log of their sum.

The logarithm function cannot be applied to a sum. The purpose of the logarithm function is to turn the log of a product into a sum of logs. The logarithm function cannot be applied to a sum.

The only way to determine the log of the sum is to take the antilogs of the given values, add them, then take the log of the result.

Assuming the base of the logarithms is 10, using the strategy just described, we can compute ...

  log(a +b) = log(10^log(a) +10^log(b)) = log(10^1.2 +10^5.6)

  ≈ log(15.848932 +398,107.17) ≈ log(398,123.02)

  ≈ 5.6000173 . . . . using base 10 logs

If these are natural logs, which are also often written as log(x), as well as ln(x), then the log of the sum is about

  log(e^1.2 +e^5.6) ≈ 5.6122026 . . . . using base e logs

The short answer is, there is not enough information. (The base of the logarithms must be known.)

Total distance travelled by the honey bee is 4km and honeybee’s displacement is 0

Displacement is defined as the shortest distance travelled by the object.

According to the question we have been given that the honeybee travelled 2km before returning to the hive.

Thus the total distance travelled by the honeybee is = 2 + 2 km

                                                                                             = 4 km

And the honeybee’s displacement = 0

Because the bee has returned to the same from where she had left and displacement is a vector quantity that has magnitude and direction and depends upon the initial and final position. So as the initial and final destination is same for the honeybee. Thus the displacement will be zero.

Hence total distance = 4km

And displacement = 0

Assets are simply subtracted from liabilities to determine net value. Your money and investments, your home and other properties you own, your automobiles, and any other valuable possessions you own are all considered assets.

Liabilities = 500 + 210,000 + 18,000 + 25,000  = 257000

Net worth = Assets - Liabilities

The rate of change in elevation will be:

R = -225m/10s = -22.5 m/s

The airplaen descends at a rate of 22.5 meters per second.

The rate in change of the elevation will be given by the quotient between the change in elevation and the time in which that change happens.

Here we know that the airplane descended 225 meters, so the change in elevation is:

C = -225m

And that change happens in 10 seconds, so the rate of change in elevation will be:

R = -225m/10s = -22.5 m/s

What is Probability ?

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Probability Formula = f/n

where,

f is the number of times an event occurs

n is the total number of trial

The probability is represented as:

P(Large | Hot)

This is calculated using:

P(Large | Hot) = n(Large and hot)/n(hot)

Using the data on the given table, we have:

P(Large | Hot)  = 22/(8 + 12 + 5)

P(Large | Hot)  = 0.88

we have no continuous curve here, the supposed function only consists of a few data pair points. and that is absolutely ok.

any function just maps a set of x (input) values to a set of y (function result) values.

A.

yes, it is a function, because every "used" x value has exactly 1 assigned y value.

when we draw a vertical line and move it across the grid, there are never 2 or more of the points in the line. always only one.

the opposite (every y value has exactly 1 x value as origin) is NOT necessary to be a function. but it would have to be true for the inverse function to be a function too.

B.

the domain is the interval or set of all valid x values.

since we have only single points, it is a set here :

{-4, -3, -2, 0, 2, 3}

C.

the range is the interval or set of all valid y values :

{-3, -1, 0, 2, 3}

D.

as we can see on the chart, the only point with x value = 2 has the y value = -3.

A possible solution for this case of collinear points is (x, AB, BC, CD, AC, AD) = (0, 18, 14, 10, 32, 42).  

In this question we have four points that are collinear, that is, that lie on the same line. Mathematically, speaking we have the following equations representing the geometric system:

BC = 14 + x             (1)

AD = 42 + x           (2)

AC = x + 32           (3)        

By (1) and (3):

AB = (x + 32) - (14 + x)

AB = 18

By (2) and (3):

CD = (42 + x) - (x + 32)

CD = 10

If x = 0, then BC, AD and AC are, respectively:

BC = 14, AD = 42, AC = 32
