Answer:
2 1/6 feet
Step-by-step explanation:
A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?
Total length of the board = 8 feet
Piece A = 3 1/2 feet
Piece B = 2 1/3 feet
Piece A + piece B
= 3 1/2 feet + 2 1/3 feet
= 7/2 + 7/3
= (21+14) / 6
= 35/6
= 5 5/6 feet
Length of the board remaining = Total length of the board - length of the two pieces
= 8 feet - 35/6 feet
= (48-35) / 6
= 13/6 feet
= 2 1/6 feet
Length of the board remaining = 2 1/6 feet
A store sells watches for $69.99 each and watch batteries for $9.50 each. Justin is buying 2 watches and x number of watch batteries. Which equation can be used to find y, the total price Justin must pay in dollars?
A y = 139.98x + 9.50x
B y = 69.99x + 9.50
C y = 9.50x + 69.99
D y = 9.50x + 139.98
Answer:
D. y= 9.50x + 139.98
Step-by-step explanation:
69.99 x 2 = 139,98

What is the Mean, Median, Mode, and Range for number 4
Please help
Answer:
Mean: 63. Median: 69. Mode: 41. Range: 51.
Step-by-step explanation:
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list. The "range" of a list a numbers is just the difference between the largest and smallest values.
Hope this helps!
A swim instructor would like to test the effect of a new swim technique versus the standard technique for a group of 25 competitive swimmers.
The swim instructor divides the students by class (junior or senior), and then randomly allocates half of the 14 juniors and 5 of the 11 seniors to receive instruction on the new technique.
During swim practice, the instructor times the juniors as they race against each other to see if those who learned the new technique outperform their peers. The instructor does the same for the seniors.
At the end of practice, the instructor compares the average swim time for both juniors and seniors among those who did and did not use the new technique.
A) The instructor should place the 25 student names on slips of paper and place them in a hat. Twelve of the slips should be drawn out and those students should receive the instruction on the new technique.
B) The instructor should place the names of the 14 juniors on slips of paper and place them in one hat. The 11 seniors’ names should be placed on slips of paper and placed into a separate hat. The instructor should randomly select 7 juniors and 5 seniors to receive instruction on the new technique.
C) For each student, the instructor should flip a coin. If the coin lands on heads, the student will receive instruction on the new technique. If the coin lands on tails, the student will not receive instruction on the new technique.
D) The students should line up alphabetically and count off by 2s. Every student who gets a 1 will receive instruction on the new technique. Every student who gets a 2 will not receive instruction on the new technique.

The parallelogram shown below has an area of 35 units^2 2 squared. Find the missing height. h =h=h, equals units
Answer:
h = 5 units
Step-by-step explanation:
Given that,
The area of the parallelogram, A = 35 unit²
In the attached figure, we can see that the base is 7 unit.
We know that,
Area of a parallelogram, A = b × h
So,
[tex]h=\dfrac{A}{b}\\\\h=\dfrac{35}{7}\\\\h=5\ units[/tex]
So, the value of h is equal to 5 units.

A town government is designing a new bus system. The planners are deciding where to put the different bus stops. They want to pick a set of bus stop locations that will minimize the distance anyone needs to walk in order to get to any bus stop in town. What term best defines this kind of problem
Answer:
Optimisation Problem
Explanation:
Optimisation Problem is a mathematical economics, computer science problem - which finds the best solution from all feasible solutions (based on constraints & other aspects).
The problem might be in form of maximisation or minimisation. The bus system designing is based on minimizing walking distance. Thus is an optimisation problem.

A car travels 220 miles in 4 hours. If the car travels at the same speed, how far will it have traveled after 6 hours?
Answer: 330
Step-by-step explanation:
220 divided by 4 is 55 meaning 55x4=220 so in that case 55x6=330

someone help me quickly
pls help with these math problems
Answer:
Step-by-step explanation:
1)
First we add what we know for y into the second equation.
5x - 4(x +2)= -3
From there, we simplify it
5x-4x-8= -3
x-8=-3
Now we get the x on its own
x=5
and now we add x=5 into the first equation that we had and simplify to find y
y=5+2
y=7
So the answer is x=5, y=7 or (5,7)
2)
For this one we do the same thing as with 1.
Add what we know for y (bottom equation) to the top equation
3x-8(x-8)=24
Now we simplify
3x-8x+64=24
-5x+64=24
And now solve for X
-5x=-40
x=8
And then substitute x=8 to find y
y=8=8
y=0
So the answer is x=8, y=0 or (8,0)

5 divided by 14?
......................................
Answer:
0.3571
Step-by-step explanation:
Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:
14[tex]\sqrt{x}[/tex]5
Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).
Therefore, put 0 on top:
14[tex]\sqrt{x}[/tex]0 5
Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.
14 0
[tex]\sqrt{x}[/tex]5
0
Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.
14 0
[tex]\sqrt{x}[/tex] 5
-0/5

How many grams are 7.00 x 1022 molecules of NaOH?
Answer:
46.5
explanation
6.022*10^23 molecules=40g.
7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g are 7.00 x 10²² molecules of NaOH.
What is mole?The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
given number of atoms of NaOH= 7.00 x 10²² atoms
Substituting the values
mole=7.00 x 10²²÷ 6.022×10²³
mole =0.116 moles of NaOH
mass of NaOH= Molar mass of NaOH× moles of NaOH
= 40 × 0.116
= 4.65g
Therefore, 4.65g are 7.00 x 10²² molecules of NaOH.
