Answer:
(-5, 4)
Step-by-step explanation:
if you are moving up and down only the y part of the coordinate will change so 5 going 6 down would put you at -1 then going 5 up would put you at 4
Final answer:
Starting at (-5, 5), moving down 6 units and then up 5 units results in a final position of (-5, 4).
Explanation:
If you start at the point (-5, 5) and then move down 6 units, your vertical position decreases by 6. That means you subtract 6 from 5, the y-coordinate, resulting in -1. However, if you then move up 5 units, you're adding 5 back to your y-coordinate. So, you take -1 and add 5, which results in 4. Your final position then is still at the same x-coordinate, -5, but with a new y-coordinate of 4. Therefore, the point you end up at is (-5, 4).
How many ⅛-pint tubes can be filled
from a ¾-pint bottle of hydrogen
peroxide?
Answer:
6
Step-by-step explanation:
3/4 to get the common denominator of 8 would be 6/8. Then, divide by 1/8 to get 6.
48 ⅛-pint tubes can be filled.
To find out how many tubes can be filled:
Convert ¾ pint to eighths: ¾ pint = 6 eighths
Divide the total eighths by the eighths per tube: 6 eighths ÷ ⅛ eighths per tube = 6 ÷ 0.125 = 48 tubes
So, from a ¾-pint bottle of hydrogen peroxide, 48 ⅛-pint tubes can be filled.

Rework problem 23 from section 2.4 of your text involving congressional committees. Assume that the committee consists of 6 Republicans and 5 Democrats. A subcommittee of 4 is randomly selected from all subcommittees of 4 which contain at least 1 Democrat. What is the probability that the new subcommittee will contain at least 2 Democrats?
Answer:
21/22 or 0.955 (3 sf)
43/66 or 0.652 (3 sf)
Step-by-step explanation:
P(atleast 1 Democrat)
= 1 - P(no Democrat)
= 1 - (6C4/11C4)
= 1 - 1/22 = 21/22 or 0.955 (3 sf)
P(atleast 2 Democrats)
= 1 - P(0 or 1 Democrats)
= 1 - 1/22 - (6C3×5C1)/11C4
= 1 - 1/22 - 10/33
= 43/66 or 0.652 (3 sf)
The probabilities that the new subcommittee will contain at least 2 Democrats are 0.955 (least 1) and 0.652 (least 2).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
To calculate the probability that the new subcommittee will contain at least 1, Democrat
⇒ 1 - P(no Democrat)
⇒ 1 - (⁶C₄/¹¹C₄)
⇒ 1 - 1/22
⇒ 21/22
⇒ 0.955
To calculate the probability that the new subcommittee will contain at least 2, Democrat
⇒ 1 - P(0 or 1 Democrats)
⇒ 1 - 1/22 - (⁶C₃×⁵C₁)/¹¹C₄
⇒ 1 - 1/22 - 10/33
⇒ 43/66
⇒ 0.652.
Thus, the probabilities that the new subcommittee will contain at least 2 Democrats are 0.955 (least 1) and 0.652 (least 2).

The length of a rectangle is three times the width. the parameter is 240 inches. find the length and width
Answer:
L = 90 inches
W = 30 inches
Step-by-step explanation:
Give the length of a rectangle L is three times the width
That’s
L = 3w
And perimeter = 240 inches
Recall that the perimeter of a rectangle is given by
P = 2(L + W)
L = 3w
We now have two equations
Now substitute 3w for L in The above formula and 240 for P.
We have
240 = 2(3w + w)
Distribute 2 into (3w + w)
240 = 2 x 3w + 2 x w
240 = 6w + 2w
240 = 8w
Divide both sides by 8
240/8 = 8w/8
30 = w
W = 30inches
Now substitute 30 for w into either of the above equations to get L .
Using
L = 3w
L = 3 x 30
L = 90 inches
L = 90 inches and
W = 30 inches

Tim installs 50 square feet of his floor in 45 minutes. At this rate, how long does it
take him to install 495 square feet?
Answer:
9 hrs and 10 mins
Step-by-step explanation:
We can convert this into a proportion. 50/45 = x/495. Cross-multiply to get 45x = 50*495. Divide both sides by 45 to get x = 50*11 = 550 minutes or 9 hrs and 10 mins
Answer: 445.5 minutes
Step-by-step explanation:
Hi, to answer this we have to apply a proportion:
Proportion: square feet / time (minutes)
Tim installs 50 square feet of his floor in 45 minutes: 50/45
For 495 square feet: 495/x
Where x is the time it takes Tim to install 495 square feet of his floor.
50ft/45min = 495ft/x min
Solving for x
x = 495 / (50/45)
x= 445.5 minutes

The length of a rectangle is the width minus 3 units. The area of the rectangle is 54 units. What is the width, in units, of the rectangle ?
Final answer:
To find the width of the rectangle, you can set up an equation using the given information and the formula for the area of a rectangle. Solve the equation to find the width of the rectangle, which is 9 units.
Explanation:
To find the width of the rectangle, we need to use the given information. We are told that the length of the rectangle is the width minus 3 units. Let's call the width of the rectangle 'w'.
So, the length of the rectangle is w - 3 units. The area of the rectangle is given as 54 square units. We can set up an equation using the formula for the area of a rectangle: Length x Width = Area.
Substituting the length expression into the equation, we get (w - 3)w = 54. Simplifying the equation gives us w² - 3w - 54 = 0. We can solve this quadratic equation to find the width of the rectangle.
Using factoring or the quadratic formula, we find that the width of the rectangle is 9 units.

A math teacher needs to choose 6 students from class of 30 to go to the library. How many different groups can she select?
Possible answers
A 180
B 427,518,000
C 593,775
D none of the choices are correct
To determine the number of different ways a math teacher can select 6 students from a class of 30, we use the combination formula C(30, 6) = 30! / (6! * (30 - 6)!), which gives us 593,775 different possibilities. Therefore, the correct answer is C, 593,775.
The math teacher needs to select 6 students from a class of 30 students to go to the library, which is a combinatorial problem in mathematics. The number of ways to choose k students from a group of n students without regard to the order is given by the combination formula:
C(n, k) = n! / (k! * (n - k)!), where n! is the factorial of n and equals n multiplied by all positive integers less than n, and k is the number of students chosen.
Applying the formula for our situation:
C(30, 6) = 30! / (6! * (30 - 6)!)
= (30 * 29 * 28 * 27 * 26 * 25) / (6 * 5 * 4 * 3 * 2 * 1)
= 593,775
So there are 593,775 different ways the teacher can select 6 students from a class of 30. Hence, the correct answer is C, 593,775.
You buy a printer for $79.80 and a scanner for $67.10; you receive a $11 mail-in rebate for the printer and a $17 mail- in rebate for the scanner. a) If each envelope costs $0.15 and each stamp costs $0.37, calculate the total cost after the rebates. b) How much is the actual rebate after your expenses
The total cost of the printer and scanner after the rebates is $117.86, and the actual rebate after expenses is $26.96.
Explanation:For part a, first, add up the cost of the printer and scanner: $79.80 (printer) + $67.10 (scanner) = $146.90 (total original cost). Then calculate the mail-in rebates: $11 (printer rebate) + $17 (scanner rebate) = $28 (total rebates). However, you incur some costs when mailing these rebates. You need one envelope and one stamp for each rebate so multiplying the price of the envelope and the stamp by 2 gives us 0.15*2 + 0.37*2= $1.04. We subtract the $28 (rebate) and this $1.04 (mail cost) from the original cost ($146.90), giving us a final cost of $146.90 - $28 - $1.04 = $117.86.
For part b, the actual rebate after your expenses is the total value of the rebates ($28) minus the mail-in costs ($1.04), which ends up being $28 - $1.04 = $26.96.
