A rectangle has an area of 135 ft 2 . What is the length, if the width is 9 ft?
Answer:
15 ft
Step-by-step explanation:
A=LxW
135 ft2 =m X 9ft
Divide 135 by 9
& that equals 15ft.
To check your answer, you multiply 15X9 and that equals 135. So the length of the rectangle is 15ft.

its C:)The Science Club went on a two-day field trip. The first day the members paid $70 for transportation plus $19 per ticket to the planetarium. The second day they paid $100 for transportation plus $16 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.
Answer:
$170 + $35n
Step-by-step explanation:
Given that:
First day:
Transport fare = $70
Fee per ticket = $19
2nd day:
Transport fare = $100
Fee per ticket = $16
Total cost in dollars for the two days for n members
Number of members = n
First day:
70 + 19n
Second day :
100 + 16n
Totak cost :
(70 + 19n) + (100 + 16n)
70 + 100 + 19n + 16n
170 + 35n
$170 + $35n

Find(x^3+8x^2-25x-193) divide (x-5) by using synthetic division.
Answer:
x^2+13x+40 remainder 7. (or 7/(1-5))
Step-by-step explanation:
Answer:
x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]
Step-by-step explanation:
Using Synthetic division
dividing by ( x - 5) , thus use h = 5
5 | 1 8 - 25 - 193
↓ 5 65 200
+ + +
---------------------------------
1 13 40 7 ← remainder
quotient = x² + 13x + 40
Thus
[tex]\frac{x^3+8x^2-25x-193}{x-5}[/tex] = x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]

The best way to help is to get some water or get some sleep.It is either because you didn't get enough sleep or that you are dehydrated.
Step-by-step explanation:
Answer:
Drink a soda the instant you feel one coming on- sugar and caffeine tend to help.
If you can, try a good chiropractor- they can do adjustments that help with so many things including splitting headaches.
Try an OTC medicine.
sleep, dark, quiet, calm- try not to think too much and stay hydrated. maybe try carbonated water.
try to massage your neck yourself. it could help.
try to use a cold or a hot compress on your head.
Bananas. A tried and true natural headache reliever, bananas have potassium, magnesium, B vitamins, and complex carbohydrates, all components that contribute to headache relief.
The taste and smell of green apples have shown to help dim or lessen the intensity of migraines.
Hot packs and heating pads can relax tense muscles. Warm showers or baths may have a similar effect. Drink a caffeinated beverage. In small amounts, caffeine alone can relieve migraine pain in the early stages or enhance the pain-reducing effects of acetaminophen (Tylenol, others) and aspirin.

please help what is the value of u
Answer:
34
Step-by-step explanation:
It is an isosceles triangle.
112 + u + u =180 {Angle sum property}
112 + 2u = 180
2u = 180 - 112
2u = 68
u = 68/2
u = 34

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = 2x - 4
y = -x + 5
Step 2: Solve for x
Substitution
Substitute in y: 2x - 4 = -x + 5Add x to both sides: 3x - 4 = 5Add 4 to both sides: 3x = 9Isolate x: x = 3Step 3: Solve for y
Define equation: y = -x + 5Substitute in x: y = -3 + 5Add: y = 2How do I make 2x+y+ 3X - 7 y=mx+b
Step-by-step explanation:
[tex]2x + y + 3x - 7y \\ = (2x + 3x) + (y - 7y) \\ = (5x) + ( - 6y) \\ = 5x - 6y \\ = mx + b \\ where \: \: m = 5 \\ where \: \: b = - 6y[/tex]

Find the slope of 6x – 3y = 5
Answer:
slope is 2
Step-by-step explanation:
simplify this equation so that you can get to "y ="
your equation is: 6x - 3y = 5
start by subtracting 6x from both sides: -3y = -6x - 5
then divide both sides by -3 to isolate y: y = 2x - 5/3
so now we can clearly see that the slope is 2, since that is what is right next to x
How do you make x the subject of the formula?
Step-by-step explanation:
Open the brackets
px - pq = x
Add pq to both sides.
px = x + pq
Subtract x from both sides.
px - x = pq
x (p - 1) = pq
Divide both sides by (p - 1)
x = pq/(p-1)

Let $n$ be the smallest composite number such that it can be written as the product of two positive integers that differ by 10?
Answer:
The smallest composite number for [tex]n[/tex] is 24, which is the product 2 and 12.
Step-by-step explanation:
A composite number is an integer that is not a prime number, that is, a number that can be divided only by one and itself. Let be [tex]n[/tex] the smallest composite number such that there are two positive integers [tex]x[/tex], [tex]y[/tex] such that [tex]x - y = 10[/tex] and [tex]x\cdot y = n[/tex]. [tex]n[/tex] is a positive integer, since both integers are positive. Then, we can use the following formula:
[tex](y+10)\cdot y = n[/tex]
[tex]y^{2}+10\cdot y = n[/tex]
[tex]y^{2}+10\cdot y - n = 0[/tex] (1)
We obtain the roots of this second order polynomial by means of the Quadratic Formula:
[tex]y = \frac{-10\pm \sqrt{10^{2}-4\cdot (1)\cdot (-n)}}{2}[/tex]
[tex]y = -5\pm \sqrt{25+n}[/tex] (2)
Given that [tex]y > 0[/tex], we must observe the following inequation:
[tex]-5\pm \sqrt{25+n}>0[/tex] (3)
[tex]\sqrt{25+n} > 5[/tex]
[tex]25 + n > 25[/tex]
[tex]n > 0[/tex]
Let is find the values of x and y by iterative means:
x = 11, y = 1
[tex](11)\cdot (1) = 11[/tex]
11 is not a composite number, but a prime number.
x = 12, y = 2
[tex](12)\cdot (2) = 24[/tex]
24 is a composite number, which contains the following product of prime numbers:
[tex]2^{3}\cdot 3 = 24[/tex]
The smallest composite number for [tex]n[/tex] is 24, which is the product 2 and 12.
Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60 detergent and 40% water in a 5 gallon buckets. To make this he combined some 80/20 mixture with some pure water in each 5 gallon bucket. How much gallons of pure water does Manny add to each 5 gallon bucket.
Answer:
1.67 gallons
Step-by-step explanation:
Given that:
Original mixture contains 80% detergent and 20% water in a 15 gallon bucket.
New Mixture to contain 60% detergent and 40% water of 5 gallon bucket.
To find:
Volume of Pure water to be added to each 5 gallon bucket to obtain the new mixture.
Solution:
First of all, let us calculate the answer by adding pure water to 15 gallon bucket.
Let the number of gallon of water to be added = [tex]x[/tex]
New volume = (15+[tex]x[/tex]) gallons
Now, let us compare the number of gallons of water in the mixture before and after.
[tex]15\times 20\% + x = (15+x)\times 40\%\\\Rightarrow (3+x)\times 5 = (15+x)\times 2\\\Rightarrow 15+5x=30+2x\\\Rightarrow 3x=15\\\Rightarrow x =5\ gallons[/tex]
Therefore, to a 15 gallon bucket (80% detergent and 20% water)of detergent mixture, if we add 5 gallons of pure water , it will become 60% detergent and 40% water.
To a 5 gallon bucket, the number of gallons of water to be added = [tex]\frac{5}{3} =\bold{1.67\ gallons}[/tex]
