Connor has five nickels in one hand and some dimes in his other hand. He has more than two times as many dimes as nickels. He has fewer than three times as many dimes as nickels.
Answers
Complete question :
How many dimes might he have?
How many coins would he have altogether?
Answer:
11, 12, 13, 14 ;
16, 17, 18, 19
Step-by-step explanation:
Let :
Nickel = n
Dimes = d
Total number of nickels = 5
He has more than 2 times as many dimes as nickels ;
d > 2n
d > 2*5 ; d > 10
He has fewer than 3 times as many dimes as nickels;
d < 3n
d < 3*5 ; d < 15
Meaning he has more than 10 dimes but less than 15.
10 < d < 15
So, d could be ;
11, 12, 13, 14
Number of coins altogether :
11 + 5 = 16
12 + 5 = 17
13 + 5 = 18
14 + 5 = 19

Answer:
The slope is 2
Step-by-step explanation:

m = y/x —> 4/2 —> 2
m = 2
Answer:
[tex]\boxed {\boxed {\sf m=2}}[/tex]
Step-by-step explanation:
The formula for slope is:
[tex]m= \frac {y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are the points on the line.
We are given the points (-3,1) and (-1,5). Therefore,
[tex]x_1= -3 \\y_1= 1 \\x_2= -1 \\y_2=5[/tex]
Substitute the values into the formula.
[tex]m= \frac {5-1}{-1--3}[/tex]
Solve the numerator.
[tex]m= \frac{4}{-1--3}[/tex]
Solve the denominator.
-1 --3= -1+3 =2[tex]m=\frac{4}{2} \\[/tex]

у = х + 3
у =-2x-3
Answers
Answer:
x = - 2, y = 1
Step-by-step explanation:
Comparing both the equations,
→ y = y → x + 3 = - 2x - 3
=> x + 3 = - 2x - 3
=> x + 2x = - 3 - 3
=> 3x = - 6
=> x = - 6/3 = - 2
Substitute the value of x in any of these:
=> y = x + 3 = - 2 + 3 = 1
Answer:
Step-by-step explanation:
If a solution exists for the system of equations y=y so we can say
x+3=-2x-3 Add 2x to each side
3x+3=-3 Subtract 3 from each side
3x=-6. Divide each side by 3
x=-2, since y=x+3
y=-2+3
y=1
So the solution to the system of equations is the point (x,y)=(-2,1)
Is (5,2) a solution to this system? x+4y=13 x-y=3 *
Answers
Answer:
yes
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
x + 4y = 13
x - y = 3 Subtracting:
0 + 4y - (-y) = 13 - 3
5y = 10
y = 2.
Plug y = 2 into the second equation:
x - 2 = 3
x = 5.

the number of squirrels in a park at the end of the month
Answers
Using the given recursive function, we have that:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.
What is the recursive function for this problem?
The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:
[tex]S_{n+1} = 1.6S_n - 30[/tex]
For this problem, we have that at the amount at the end of May is of 70, hence:
[tex]S_{5} = 70[/tex]
Hence, we find the amounts at the end of June, July and August, as follows:
[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].Hence:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.

Write a function to represent the set of ordered pairs.
{(2, -1), (4, 5), (6, 15), (8, 29)}
Answers
Step-by-step explanation:
ES6 has a new Set data structure for storing sets of unique objects. However it is based on object references as opposed to value comparisons. As far as I can tell this makes it impossible to have a set of pairs of numbers without stringifying.
For example, typing in Chrome's console (needs Chrome 38+):
> var s = new Set(); < undefined > s.add([2, 3]); < Set {[2, 3]} > s.has([2, 3]) < false <--- was hoping for 'true'
This appears to be by design: since I passed a different array of [2, 3] to has(), it returns false, because although the contents is the same it only looks at object references, and I allocated a new and different array to pass to has(). I would need to store a reference to the original array I passed to add() to check with has(), but this is not always possible. For example if the number pairs represent co-ordinates, I might need to check if the set has [obj.x, obj.y], but this will always return false since it allocates a new array.
The workaround is to stringify the arrays and key on strings like "2, 3" instead. However in something performance-sensitive like a game engine, it is unfortunate if every set access needs to make a string allocation and convert and concatenate number strings.
Does ES6 provide any feature to solve this problem without stringifying, or is there any feature on the horizon with ES7 that could help as well?

As you've noted [2, 3] === [2, 3] is false, meaning you can't use Set like this; however, is Set really the best option for you?
You may find that using a two-level data structure like this will be better for you
var o = {}; function add(o, x, y) { if (!o[x]) o[x] = {}; o[x][y] = true; } function has(o, x, y) { return !!(o[x] && o[x][y]); } function del(o, x, y) { if (!o[x]) return; delete o[x][y]; // maybe delete `o[x]` if keys.length === 0
You have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long. How many feet of streamers do you have left?
Answers
Answer:
48
Step-by-step explanation:
If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.
What is Unit of Measurement ?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that we have a 84 feet of streamers.
You cut 24 pieces that are each 1/2 yard long.
Need to find the feet of streamers we left.
We know that 1 yard is equal to 3 feet.
Therefore, 1/2 yard is equal to 1.5 feet.
The total length of the streamers that were cut is:
24 pieces x 1.5 feet/piece = 36 feet
To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:
84 feet - 36 feet = 48 feet
Therefore, you have 48 feet of streamers left.
