A rectangle has a length of 26 yards less than 8 times it’s width. If the area of the rectangle is 682 square yards, find the length of the rectangle.
Answers
Answer:
Length is 62 yards
Step-by-step explanation:
A = wL
L = 8w-26
682 = w(8w-26)
682 = 8w^2 -26w
0 = 8w^2 - 26w - 682
Use the quadratic formula (it's really hard to type it but just look it up if you want to see the explanation)
w = 11
L = 8(11) - 26 = 62 yards
Check: 62(11) = 682

Riley makes a necklace for his sister. Twelve beads take up 5 inches of string.
How many beads fit on 1 foot of string?
Answers
Hey how was your day? What did you do today?
Answer:
28.8
If rounded 28
Step-by-step explanation:
If every 12 beads takes up 5 inches that means that 1 foot (12 inches) would be divided by 5 (12/5) (A. 2.4) and then multiplied by 12. which would give you 12.8 or since you cant have 28.8 beads, you can only put on 28 when rounded.
Solve: 3x + 2y = 11 and 6x - 2y = 25.
Answers
Answer:
x = 4, y = -0.5
or (4,-0.5)
Step-by-step explanation:
Given:
3x + 2y = 11. . . (i)6x - 2y = 25. . . . (ii)Solution:
Adding equations (i) and (ii):
==> (3x + 2y) + (6x - 2y) = 11 + 25
2y gets cancelled:
==> 9x = 36
dividing the equation by 4:
==> x = 4
Substituting 4 for x in equation (i):
==> 3(4) + 2y = 11
==> 12 + 2y = 11
subtracting 12 from both sides:
==> 2y = 11 - 12
==> 2y = -1
dividing both sides by 2:
==> y = -1/2
==> y = -0.5

14 students have volunteered for a committee. Eight of them are seniors and six of them are juniors. (a) How many ways are there to select a committee of 5 students
Answers
======================================================
Explanation:
We have five slots to fill, which I'll label A through E.
There are,
14 choices for slot A13 choices for slot B12 choices for slot C11 choices for slot D10 choices for slot EEach time we fill up a slot, we count down by 1.
This gives 14*13*12*11*10 = 240,240 different permutations. If order mattered, then this would be the answer.
However, order doesn't matter on a committee without rankings. Each member has the same rank as any other.
Within any group of 5 people, there are 5! = 5*4*3*2*1 = 120 ways to arrange them. This means we divide that 240,240 figure by 120 to find the number of combinations.
There are (240,240)/(120) = 2002 different combinations.
---------------------------------------
Here's how we could have done the problem using the nCr combination formula.
Plug in n = 14 and r = 5.
n C r = (n!)/(r!(n-r)!)
14 C 5 = (14!)/(5!*(14-5)!)
14 C 5 = (14!)/(5!*9!)
14 C 5 = (14*13*12*11*10*9!)/(5!*9!)
14 C 5 = (14*13*12*11*10)/(5!)
14 C 5 = (14*13*12*11*10)/(5*4*3*2*1)
14 C 5 = (240240)/(120)
14 C 5 = 2002

Answers
First you distribute the -3. So -3 times x which is -3x and -3 times -1 which is positive 3. Therefore you get y+2=-3x+3.
Then you subtract the 2 from both sides. 2-2=0, so you have just y. Now subtract 2 from the 3 on the right and you get 1. Therefore you get y=-3x+1.

I provided a Picture for the graph! Thanks a ton!
Answers
Answer to the 1st question: 8 years
Answer to the 2nd question: The year 2022
=======================================================
Further explanation:
x = number of years after 2008
y = average price of a new car
The prices are going up by $1250 per year on average. This is the slope because the slope is the rate of change. So m = 1250.
The y intercept is b = 30100 as this is the price in 2008.
This leads us to go from y = mx+b to y = 1250x+30100
Plug in x = 0 and you should get y = 30100.
Also, plugging x = 6 into the equation leads to y = 37600 to help confirm things.
-----------------
Next, we plug in y = 47600 and solve for x.
y = 1250x+30100
47600 = 1250x+30100
47600-30100 = 1250x
17500 = 1250x
1250x = 17500
x = 17500/1250
x = 14
This means 14 years after the year 2008 is when the average new car price will be $47,600.
2008+14 = 2022
2022-2014 = 8
Therefore, 8 years after 2014 (aka the the year 2022) is when the new car average price will be $47,600.
A bag contains sixty marbles. Adam takes 18 of them. The rest are shared equally between Oscar, Priya and Daisy. How many marbles does Daisy get?
Answers
Answer:
14
Step-by-step explanation:
Take away the marbles that adam has
60-18 = 42
There are 42 marbles to divide between Oscar, Priya and Daisy.
Divide 42 by 3
42/3 = 14
Daisy gets 14 marbles
Daisy gets 14 marbles
How to determine the amount Daisy got?The number of marbles in the bag is:
Marbles = 60
When Adam took 18 marbles, the remaining number of marble is:
Marbles = 60 - 18
Marbles = 42
When the remaining marbles are shared by Oscar, Priya and Daisy.
The amount by Daisy is:
Daisy = 42/3
Daisy = 14
Hence, Daisy gets 14 marbles
