a and b are two natural numbers such that
a b
a< 512 < b < 608. What is the difference between
the biggest and smallest possible values of a + b
Answer:
604
Step-by-step explanation:
Recall that the Natural Numbers consist of the set of positive integers. Therefore, the minimum value of a is "1", and its maximum value is 511 (it has to be smaller than 512)
On the other hand, "b" has its minimum value as 513 (must be larger than 512); and has its maximum value as 607.
Then the maximum possible value of a + b would be: 511 + 607 = 1118
and the minimum possible value of a + b is given by: 1 + 513 = 514.
And the difference between these two numbers is:
1118 - 514 = 604
You purchase a video game for $150. You make a down payment of $25. You pay the rest of the money you owe in 5 equal monthly payments with no interest. How much is each monthly payment?
Answer: So basically for this you just need to multiply. The answer is 25
each month since 5x30=150 and you already made a down payment of 25. So 5x30=150-25=125.

A painter is paid a standard hourly rate and makes $41.25 for five hours of painting. How much is the painter paid for eight hours of painting
A.$8.25
B.$24.75
C.$66.00
D.$74.25
Let the random variable Q represent the number of students who go to a certain teacher office hour each day. The standard deviation of Q is 2.2. Which of the following is the best interpretation of the standard deviation?
a. On average, the number of students going to an office hour varies from the mean by about 2.2 students.
b. For a randomly selected office hour, the number of students who will go is 2.2.
с. For a randomly selected office hour, the number of students expected to go will vary from the mean by 2.2 students.
d. For a random selection of office hours, the average number of students expected to go is 2.2.
e. For a random selection of office hours, the E average number of students expected to go will vary from the mean by 2.2 students.
Answer:
A: On average, the number of students going to an office hour varies from the mean by about 2.2 students.
Step-by-step explanation:
We are given that:
- Random variable Q is used to represent the number of students who go to a certain teachers office hour each day.
-The standard deviation of Q is 2.2.
Now, standard deviation in relation to mean is defined as the statistic that measures the dispersion of a set of data relative to its mean.
Applying that definition to the question means that the number of students on the average varies from the mean by 2.2.
Thus, option A is correct.
Answer:
A: On average, the number of students going to an office hour varies from the mean by about 2.2 students.

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F
in right triangle RST altitude TV is drawn to hypotenuse RS If RV = 12 and RT = 18, what is the length of SV
Answer:
12
Step-by-step explanation:
Given that:
RV = 12 and RT = 18
Kindly refer to attachment for triangle diagram:
Using the altitude on hypotenus theorem :
Length of RS = 12 + a
RT² = RV * RS
18² = 12 * (12 + a)
324 = 12(12 + a)
324 = 144 + 12a
324 - 144 = 12a
180 = 12a
Divide both sides by 12
180/12 = a
15 = a
Hence, SV = 12
1/2 divided by 1/8 in simplest terms
HELP!!! IM STUCK ON THIS QUESTION!!!
Answer:
The answer is 4 simplified.
Step-by-step explanation:
The answer is 4 because when dividing you flip the second fraction you are using and you multiply instead of dividing so the equation turns into 1/2 * 8/1 and it equals 8/2 and 8/2 simplified is 4

3 times sum of a number and nine is 12
Answer:
-5 is the missing number.
Step-by-step explanation:
Let's write the equation.
Represent the number with x.
3( x + 9 ) = 12
Now, we solve for x.
Divide by 3 on both sides.
x + 9 = 4
Now, subtract by 9 on both sides.
x = -5
The number is -5.

Twenty (20.0) mL of argon gas (Ar) is stored at STP. If the temperature and pressure are both doubled, what is the new volume?
Answer:
20.0mL
Step-by-step explanation:
The general gas formula is expressed as;
P1V1/T1 = P2V2/T2
P1 and P2 are the initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
T1 and T2 are the initial and final temperature respectively
If the temperature and pressure are both doubled, then;
P2 = 2P1 and T2 = 2T1
Given
V1 = 20.0mL
Required
New volume V2
Substitute the given parameters into the formula above as shown;
P1V1/T1 = P2V2/T2
20P1/T1 = (2P1)V2/(2T1)
20 = 2V2/2
20 = V2
Hence the new volume is also 20.0mL
