Step-by-step explanation:
Step-by-step explanation:
Let x represents the number of cans of repellent and y represents the number of mosquitos,
If f be the relation from x to y,
Then by the given table,
f(x) = { (0, 11), (1, 8), (5, 2), (4,5), (2, 9), (3, 6)}
∵ If for each input in a relation has exactly one output, the relation is called a function.
Here, for each value of x there is exactly one value of y,
Hence, f(x) is a relation from x to y,
Solve for x. Round to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
take 60 degree as reference angle
using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
Answer:
x = 160
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{CD}{CE}[/tex] = [tex]\frac{80}{x}[/tex] ( multiply both sides by x )
x × cos60° = 80 ( divide both sides by cos60° )
x = [tex]\frac{80}{cos60}[/tex] = 160
Solve for x.

Answer:
n = 24
Step-by-step explanation:
Multiply the given equation by the product of denominators. Then subtract 6n and go from there.
[tex]\dfrac{6}{n-6}=\dfrac{8}{n}\\\\6n=8(n-6)\qquad\text{rid of fractions}\\\\0=2n-48\qquad\text{subtract 6n, simplify}\\\\0=n-24\qquad\text{divide by 2}\\\\\boxed{24=n}\qquad\text{add 24}[/tex]
_____
Alternate solution
Any proportion can be written 4 ways. If we write this one "sideways," we have ...
6/8 = (n -6)/n
1 -1/4 = 1 -6/n . . . . . expand in parallel fashion
6/n = 1/4 . . . . . . . . subtract 1, multiply by -1
n = 24 . . . . . . . . . multiply by 4n
__
Another alternate solution (can be done mentally)
The above "sideways" proportion can be reduced to ...
3/4 = (n -6)/n
The difference between values on the left is 1 unit. On the right, the difference between values is 6. (The numerator is 6 less than the denominator.) The denominator on the left (4) is 4 times the difference, so the denominator on the right (n) will likewise be 4 times the difference: n = 4·6 = 24. Check: 3/4 = 18/24.

Answer:
Henry had 12 cans of Xtreme diet soda, if he drinks 2 sodas each hour and ends up with 8 cans at the end of the day, how many hours did he drink?
Step-by-step explanation:
12-2h=y
y=8 and your final amount
h = hrs and your variable
12 is your constant! he only has 12 cans, which cannot change
2 is your coefficient, but you can change it to whatever you want

Answer:
Perimeter = AB + AC + BC = 26.55 units
Step-by-step explanation:
The perimeter of a triangle is the sum of lengths of all sides.
Here we have a right triangle, right-angled at C
angle B = 46°
AB = 11
We continue to calculate
AC = (11)sin(46°) = 7.91
BC = (11)cos(46°) = 7.64
Perimeter = AB + AC + BC = 26.55 units
A basketball coach had her team practice free throws. The team attempted 308 free throws altogether. They made 6 times as many free throws as they missed. How many free throws did the team miss?
Let the number missed = x
They made 6 times that amount which would be 6x
The total of missed and made is 308:
X + 6x = 308
Combine like terms
7x = 308
Divide both sides by 7
X = 44
They missed 44

Which equation represents a line which is perpendicular to the line y=-\frac{1}{8}x+3
Answer:
An equation with -8 as the slope.
Step-by-step explanation:
I can't see your choices but you need to look for an equation in which the slope is -8. A line with an opposite reciprocal slope is needed in order to be perpendicular to the line y = 1/8x + 3. The opposite reciprocal of 1/8 is -8.

Hi again, I'm here to answer!
The correct answers:
10. x = -7 2/3
11. x = 2
12. x = 3
Step-by-step explanation:
(x + 3)/2 = (x - 4)/5
(5x + 15)/10 = (2x - 8)/10
3x/10 = -23/10
x = -23/3
x = -7 2/3
(2x - 1)/3 = x/2
(4x - 2)/6 = 3x/6
x/6 = 2/6
x = 2
(3x + 1)/5 = 2x/3
(9x + 3)/15 = 10x/15
-x/15 = -3/15
x = 3

Answer:
A = 8
B = 6
C = 4
D = 7
Top = 29
Side = 20
Step-by-step explanation:
To get A on the bottom side row you divide 32 by 4 and get 8.
To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.
To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.
To get C, on the third side row, subtract B and divide by 2 and you get 4.

Cindy took her five grandchildren to the movies, where she offered to buy all of them popcorn and candy. A popcorn bag costs $4.00, and a box of candy costs $2.50. Cindy ended up spending $35.00 and purchasing one more box of candy than bags of popcorn.
Use a system of equations to model the situation above, and determine which of the following is a possible description of Cindy's purchase.
Answer:
She buys 5 boxes of popcorn and 6 boxes of candy
Step-by-step explanation:
this is because 5 times 4.00 is 20$ and 2.50 times 6 is 15$
15 + 20 is 35
so your answer is 5 boxes of popcorn and 6 boxes of candy
hope this helped :D
Answer:
B
Step-by-step explanation:
If she spent 35$ and got 1 more candy and popcorn that only leaves a single option

what is the solution to this system of linear equations 2x +y =1 3x -y= -6
Answer:
x= -1 y=3
Step-by-step explanation:
Answer:
x = -1
y = 3
Step-by-step explanation:
2x +y =1 3x -y= -6
Add the two equations together to eliminate y
2x +y =1
3x -y= -6
------------------
5x = -5
Divide by 5
5x/5 = -5/5
x = -1
2x+y = 1
2(-1) +y = 1
-2 +y =1
Add 2 to each side
y = 1+2
y =3

Answer:
Step-by-step explanation:
[tex]\frac{x+6}{x+7}-\frac{x+1}{x+2}=\frac{(x+6)*(x+2)}{(x+7)*(x+2)}-\frac{(x+1)(x+7)}{(x+2)(x+7)}\\\\[/tex]
USE FOIL method
(x +6)(x + 2) = x*x + x*2 +6*x +2*6
=x² + 2x + 6x + 12 {Combine like terms}
= x² + 8x + 12
(x+ 7)(x + 2) = x*x+ x*2 +7*x + 7*2
= x² +2x+ 7x + 14
= x² + 9x + 14
(x+1)*(x +7) = x*x + x *7 + 1*x + 1*7
=x² + 7x +x + 7
=x² + 8x + 7
[tex]\frac{x+6}{x+7}-\frac{x+1}{x+2}=\frac{(x+6)*(x+2)}{(x+7)*(x+2)}-\frac{(x+1)(x+7)}{(x+2)(x+7)}\\\\\\ =\frac{(x+6)*(x+2) - [(x+1)(x+7)]}{(x+2)(x+7)}\\\\\\= \frac{x^{2}+8x+12 -[x^{2}+8x+7]}{x^{2}+9x+14}\\\\\\=\frac{x^{2}+8x+12-x^{2}-8x-7}{x^{2}+9x+14}\\\\=\frac{5}{x^{2}+9x+14}\\\\\\\\\frac{x+6}{x+7}-\frac{x+1}{x+2}=\frac{1}{3x+1}\\\\\frac{5}{x^{2}+9x+14}=\frac{1}{3x+1}\\\\[/tex]
Cross multiply,
5*(3x+1) = x² + 9x + 14
5*3x + 5*1 = x² + 9x + 14
15x + 5 = x² + 9x + 14
x² + 9x + 14 - 5x - 5 = 0
x² + 9x - 5x + 14 - 5 = 0
Combine like terms
x² + 4x + 9 = 0
a = 1 ; b = 4 ; c = 9

Answer:
8 x 8 = 64
64 x 6 = 384 ft^2 is your answer.
Answer:
384 Sq ft
Step-by-step explanation:
multipliy 8 by 8 to get the area of one side. then because it is a cube, and all the side lengths are the same, you can just multipliy the area of one face by the amount of faces total.
8×8=64
64×6=384
384 ft²
or
384 Sq ft
