A 28-story hotel building has 18,000 square feet of space for rooms per floor. The average room is 16 ft x 28 ft. How many rooms do you have available?
Answer:
1,120 rooms
Step-by-step explanation:
You need to find out how many hotel rooms are on one floor, and then multiply that by 28. So each room is 16ft x 28ft, which comes out to be 448ft^2. Then to find how many of these rooms go onto one floor, you must divide 18,000 by 448. This equals about 40. So 40 rooms per floor, times 28 floors is: 1,120. And that's your answer! Make sure you understand how we got that. If you have any questions I can help! :)

Answer:
1. d<=200
2. f>=35
Step-by-step explanation:
Answer:
d ≤ 200
f ≥ 35
Step-by-step explanation:
"no more than 200 " means it can be equal to or less than 200. Therefore, we would use the "less than or equal to" sign, or "≤". We would put 200 at the end as it is no more than 200 feet, so 200 is the max.
"at least 35" means it is equal to or more than 35. Therefore, we would use the "greater than or equal to sign" or "≥". Since it is talking about 35 miles, we put the 35 at the end with the sign pointing away from it since 35 is the lesser number.
Remember, the "mouth" or opening of the equality sign always points to the greater or bigger number. You can think of it as an alligator wanting to eat the bigger number.

use the model to solve 4 friends equally split in one half of a pound of candy how much will each friend get
Answer:
.25 pounds
Step-by-step explanation:
Unfortunately, the type of model that is supposed to be used is not given so I will just solve what I can. So each friend gets and equal amount. If we have 1 pound in the beginning, and 4 friends, then we have to divide the candy by 4. So we do 1 pound/4=.25 pounds. If you want to go above and beyond, we can always convert the pounds into ounces and make it so each friend gets 4 ounces of candy.
In Belmont it snowed 1 inch in the morning and 1/5 of an inch in the afternoon. What was the total amount of snowfall ?
Answer:
11/5 or 1 and 2/10
Step-by-step explanation:
9514 1404 393
Answer:
1 1/5 inches
Step-by-step explanation:
It should come as no surprise that the sum of 1 and 1/5 can be written as the mixed number 1 1/5.
Recognizing that 1 = 5/5, the sum of 1 and 1/5 can also be written as the improper fraction ...
1 1/5 = 5/5 +1/5 = (5+1)/5 = 6/5
The total snowfall was 1 1/5 or 6/5 inches.

A box contains 3 green marbles, 5 blue marbles, and 7 red marbles. Three marbles are selected at random from the box, one at a time, without replacement. Find the probability that the first two marbles selected are not red, and the last marble is red. Round your answer to four decimal places.A box contains 3 green marbles, 5 blue marbles, and 7 red marbles. Three marbles are selected at random from the box, one at a time, without replacement. Find the probability that the first two marbles selected are not red, and the last marble is red. Round your answer to four decimal places.
Answer:
The probability is [tex]P(K) = \frac{ 28 }{195} [/tex]
Step-by-step explanation:
From the question we are told that
The number of green marbles is [tex]n_g = 3[/tex]
The number of red marbles is [tex]n_b = 5[/tex]
The number of red marbles is [tex]n_r = 7[/tex]
Generally the total number of marbles is mathematically represented as
[tex]n_t = n_r + n_g + n_ b[/tex]
[tex]n_t = 7 + 3 + 5[/tex]
[tex]n_t = 5 [/tex]
Generally total number of marbles that are not red is
[tex]n_k = n_g + n_ b[/tex]
=> [tex]n_k = 3 + 5[/tex]
=> [tex]n_k = 8[/tex]
The probability of the first ball not being red is mathematically represented as
[tex]P(r') = \frac{n_k}{n_t}[/tex]
=> [tex]P(r') = \frac{ 8}{15}[/tex]
The probability of the second ball not being red is mathematically represented as
[tex]P(r'') = \frac{n_k - 1}{n_t -1}[/tex]
=> [tex]P(r'') = \frac{ 8 -1 }{15-1}[/tex] (the subtraction is because the marbles where selected without replacement )
=> [tex]P(r'') = \frac{ 7 }{14}[/tex]
The probability that the first two balls is not red is mathematically represented as
[tex]P(R) = P(r') * P(r'')[/tex]
=> [tex]P(R) = \frac{ 8}{15} * \frac{ 7 }{14}[/tex]
=> [tex]P(R) = \frac{ 8 }{30}[/tex]
The probability of the third ball being red is mathematically represented as
[tex]P(r) = \frac{n_r}{ n_t -2}[/tex] (the subtraction is because the marbles where selected without replacement )
[tex]P(r) = \frac{7}{ 15 -2}[/tex]
=> [tex]P(r) = \frac{7}{ 13}[/tex]
Generally the probability of the first two marble not being red and the third marble being red is mathematically represented as
[tex]P(K) = P(R) * P(r)[/tex]
[tex]P(K) = \frac{ 8 }{30} * \frac{7}{ 13}[/tex]
=> [tex]P(K) = \frac{ 28 }{195} [/tex]

A psychology professor wants to know whether verbal ability is related to memory quality in current first-year students at her small college. Participants in the study (first-year students at her college) complete an online memory task. The students are first shown a list of 60 words. Next they are shown a list of 10 words that were on the original list. Then they are asked to identify the words on the second list that appeared on the original list. She uses the percentage of words that were correctly recognized on the original list as her measure of memory quality. She also asks the students to report several characteristics such as their age, gender, and verbal SAT score. Each of the 750 first-year students (338 males and 412 females) at her school volunteers to participate. The professor chose 75 students at random to complete the memory task and answer the questions. The average percentage of words that were correctly recognized on the original list was 68%. The professor infers that if all 750 first-year students had completed the study, the results would show that an average of 68% (plus or minus sampling error) of the words were correctly recognized as being on the original list. Which of the following are variables in the study? Check all that apply.
A. The students' verbal SAT scores
B. The students' percentage of words that were correctly recognized on the original list
C. The 75 students
D. The 750 students
Answer:
The variable are
A and B
Step-by-step explanation:
Generally we can define a variable as a name of a placeholder representing a value now considering the option to be selected from we see that
The students' verbal SAT scores is a variable because it is a phrase or a place holder that represent a value (in the is case a numerical value) which the score its self
The second option The students' percentage of words that were correctly recognized on the original list is also a variable because it is a placeholder of a name (in this case a phrase ) that represented the actual value itself
The third option The 75 students is not a variable because it is not representing any value but itself is the value
The third option The 750 students is not a variable because it is not representing any value but itself is the value

3 times what equals -18
Answer:
-6
Step-by-step explanation:
Let "what" be termed as "x".
Set the equation:
3 * x = -18
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:
(3x)/3 = (-18)/3
x = -18/3
x = -6*
*Note: When you divide a negative number with a positive number, your answer will be negative.
-6 is your answer.
~
The value of number which is 3 times to -18 is -6 .
Given,
3 *x = -18
So,
Let "what" be termed as "x".
Form the equation including the variable x ,
3 * x = -18
Isolate the variable, x.
Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:
(3x)/3 = (-18)/3
x = -18/3
x = -6
-6 is the required answer .

What is hydrogen peroxide?Hydrogen peroxide is a chemical compound that is gaseous in nature. Its viscosity is greater than that of water.
Since it is unstable it slowly decomposes in the presence of light to form water and oxygen.
The control experiment is necessary for the determination of reliability and statistical significance of results obtained.
Replication helps to ensure accuracy and randomization aids us in making quality generalizations from experimental data.
Testing the concentration of hydrogen peroxide decanted to dark bottles is the control experiment.
Testing the concentration of the species after exposure to air for 10,20 and 30 hours is randomization.

Write 37/3 as a mixed number
Answer:
12 1/3
Step-by-step explanation:
Answer:
12 1/3
Step-by-step explanation:
1. Divide the numerator by the denominator.
Divide 37 by 3, which equals 12 with a remainder of 1.
37 ÷ 3 = 12 r1
2. Find the whole number.
The whole number is the number of times the denominator divides into the numerator.
3 (the denominator) divides into 37 (the numerator) 12 times, so 12 is the whole number.
Make the remainder the new numerator.
Because the remainder (the leftover value) of dividing 37 by 3 is 12, 1 is the new numerator. The denominator is still 3. So, the mixed fraction is:
12 1/3
