39. An adult male Western Banded Gecko is 5 1/2 (or 5.5) inches long.
41. 13,000 feet long, because 1 4/9 of 9,000 is 13,000.
43. to answer the question we need to know if 35 out of 50 states is equal or greater than 3/4 if that is the case, the Constitution will be ammended, and that is represented like this:
35/50 >= 3/4
that inequality is saying that 35 states out of 50 is equal or greater than 3/4, lets simplify and modify the fractions to compare easily:
35/50 >= 3/4
7/10 >= 3/4
now we need to find the least common multiplier of 10 and 4 to take the fractions to a common denominator and compare easy. Lets multiply numerator and denominator for a correct number to get the fractions to denominator common 20, the lcm:
7/10 >= 3/4
(2/2)(7/10) >= (5/5)(3/4)
2*7/2*10 >= 5*3/5*4
14/20 >= 15/20
we can see that the inequality does not hold, so,
35/50 >= 3/4
does not hold either, therefore the Constitution cannot be ammended
40. 10 students play chess and sudoku,
30*2/5 is 12, out of 12; the number of students that play chess,5/6 play sudoku.
So..12*5/6 is 10 and that is the number of students that play both sudoku and chess.
42. Four fifths of 7/8 will be less than 7/8 (because you've multiplied by a number less than 1).
Similarly, 7/8 of 4/5 will be less than 4/5.
This means that the product will be less than each of the original factors.
answer: no
44. The answer is 7/12 because 3/4 - 1/6= 7/12
3/4 converts to 9/12 and 1/6 converts to 2/12. The domanaters stay the same, but 9-2=7. that is how you get 7/12

Answers
Answer:
Total cost of producing is 2800.
Step-by-step explanation:
Given
Ratio of profit, material cost and production labour is 5:7:13.
Material cost is 840 more than that of labour cost.
To find:
Total cost of producing the article.
Solution:
Cost of producing the article includes material cost and the labour cost.
Profit will not be included in the production cost because profit comes in the picture after the article is sold.
We are given that, the ratio is:
Profit: Material Cost: Production Labour = 5:7:13
So, we can let Material Cost = 7[tex]x[/tex] and
Production Labour = 13[tex]x[/tex]
As per the question statement:
[tex]13x-7x=840\\\Rightarrow 6x=840\\\Rightarrow \bold{x=140}[/tex]
Total cost of producing = Material Cost + Production Labour
Total cost of producing = 7[tex]x[/tex] + 13[tex]x[/tex] = 20[tex]x[/tex] = 20 [tex]\times[/tex] 140 = 2800
So, Total cost of producing is 2800.
Thirty years ago, police would check a highway for speeders by sending a helicopter up in the air and observing the time it would take for a car to travel between two wide lines placed 1/10th of a mile apart. On one occasion, a car was observed to take 7.2 seconds to travel this distance.
What is the speed of this car in miles per hour?
Answers
==============================================
Work Shown:
1/10 = 0.1
0.1 mile = 7.2 seconds
1 mile = 72 seconds (multiply both sides by 10)
1/72 mile = 1 second (divide both sides by 72)
3600/72 = 3600 seconds (multiply both sides by 3600)
50 miles = 3600 seconds
50 miles = 1 hour
The car's speed is 50 mph
Note: 1 hour = 60 min = 60*60 = 3600 seconds

Step-by-step explanation:
the photo contains the needed working out
Aron’s score is x,
Betty’s score is 2(x-5).
X+2(x-5)=320,
Distribute 2 to get
x+2x-10=320;
Add like terms (terms with x, and add 10 to both sides to get

Answer:
[tex](x^{2}-9)(x^{2} -1)[/tex]
Step-by-step explanation:
Step 1: Find what adds to _ and multiples to_
It needs to multiple to the 'c' term or 9
It needs to add to the 'b' term or -10
Step 2: Find the numbers
We know -9 and -1 make 10 and multiple to 9
-9 x -1 = 9
-9 + (-1) + -10
Step 3: Write equation in form a(x-r)(x-s)
a = 1
r = -9
s = -1
Plug in the equation to get the factored form of the equation:
[tex](x^{2}-9)(x^{2} -1)[/tex]
Therefore the factored form of the equation is [tex](x^{2}-9)(x^{2} -1)[/tex]
Quadratic equations are also a type of algebraic fractions that have factors.
The factor of [tex]x^{4} - 10x^{2} + 9 = (x -3)(x + 3)(x - 1)(x + 1)[/tex]
In order to completely factor [tex]x^{4} - 10x^{2} + 9[/tex] we would apply the formula:
a(x-r)(x-s)
To find the variables a, x, r and s, we have to love at the coefficients of [tex]x^{2}[/tex] which is -10 and the term 9 and find out what can we multiply together to give us 9 and add together to give us -10
That would be , -9 and - 1 because:
-9 x -1 = 9
-9 + (-1) = -10
Hence: the value for a = 1
, r = -9 and s = -1
Putting this into the equation:
1(x -(-9)(x - (-1))
Hence, we have:
[tex](x^2-9)( x^{2} - 1)[/tex]
Factorizing the above expression further, we have
[tex](x - 3)(x + 3)(x - 1)(x + 1)[/tex]
Therefore, the factor of [tex]x^{4} - 10x^{2} + 9 = (x -3)(x + 3)(x - 1)(x + 1)[/tex]

e Ann, Claire, and Josh collect stickers. One week, Ann collects 7 more stickers than Josh. Josh collects twice as many stickers as Claire. If they collect a total of 157 stickers, how many stickers did each collect?
Answers
Answer: Ann = 67 Josh = 60 Claire = 30
Step-by-step explanation: You get the equation 5x+7 = 157. You get the equation because for example, Claire = x then josh = 2x and Ann = 2x + 7. You do all the math and boom! You get the answer :)
The number of stickers collected are:
Ann = 67
Claire = 30
Josh = 60
Given,
Ann, Claire, and Josh collect stickers.
One week, Ann collects 7 more stickers than Josh.
Josh collects twice as many stickers as Claire.
Total tickets collected = 157 stickers.
We need to find out how many stickers each collected.
Let the tickets collected by Ann, Claire, and Josh be A, C, and J.
We can write the following equation:
Ann collects 7 more stickers than Josh.
A = 7 + J _______(1)
Josh collects twice as many stickers as Claire.
J = 2C_______(2)
Total tickets collected = 157 stickers.
A + C + J = 157 ______(3)
Solve the equation (1), (2), and (3).
A = 7 + J _____(1)
J = 2C _______(2)
A + C + J = 157 ______(3)
Put J = 2C in A = 7 + J
A = 7 + 2C ______(4)
Put (2), (4) in (3)
7 + 2C + C + 2C = 157
7 + 5C = 157
Subtracting 7 on both sides.
7 + 5C - 7 = 157 - 7
5C = 150
Dividing both sides by 5.
C = 30
Putting C = 30 in J = 2C
J = 2x30 = 60
J = 60
Putting J = 60 in A = 7 + J
A = 7 + 60
A = 67
Thus the number of stickers collected are:
Ann = 67
Claire = 30
Josh = 60

Step-by-step explanation:
Let be [tex]f(x) = -x^{2}+3\cdot x[/tex], such that:
[tex]f'(x) = \frac{f(x+h)-f(x)}{h}[/tex]
Hence,
[tex]f(x+h) = -(x+h)^{2}+3\cdot (x+h)[/tex]
[tex]f(x+h) = -(x^{2}+2\cdot x\cdot h + h^{2})+3\cdot x + 3\cdot h[/tex]
[tex]f(x+h) = -x^{2}+(3-2\cdot x) \cdot h - h^{2}+3\cdot x[/tex]
[tex]f(x) = -x^{2}+3\cdot x[/tex]
Then,
[tex]f'(x) = \frac{-x^{2}+(3-2\cdot x)\cdot h-h^{2}+3\cdot x+x^{2}-3\cdot x}{h}[/tex]

Answers
Answer:
10 Ships
Step-by-step explanation:
Khan Academy
The number of ships Astrid can build is 10, assuming she receives the maximum possible amount of wood.
What is multiplication is mathematics?Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. In math, multiply means the repeated addition of groups of equal sizes.
Given that:
Astrid receives a delivery of 4 tons of wood each day.
The deliveries can continue for 100 days at most.
At most, she received amount of wood = 4 × 100 tons = 400 tons.
Each ship requires 40 tons of wood.
Number of ships required = (400÷40) = 10.
Each ship accommodates 300 sailors.
She have to build enough ships to accommodate = (300 × 10) = 3000 sailors.
Again, she wants to build enough ships to accommodate at least 2100 sailors.
As 3000>2100; the number of ships Astrid can build is 10.

Terry is filling spherical water balloons with a faucet that puts out 100 cm^3 of water per second. At least rate, it takes Terry 6 seconds to fill a balloon. What is the radius of a filled balloon?
Answers
Answer:
its 5 cm
Step-by-step explanation:
its what I got off of Khan
The radius of a filled balloon is approximately 5.22 cm.
What is the volume of a sphere?The volume of a sphere is given by the formula V = (4/3)πr³, where V is the volume and r is the radius.
Let's first find the volume of a filled balloon.
Since Terry can fill a balloon in 6 seconds and the faucet puts out 100 cm³ of water per second, the volume of a filled balloon is:
V = 6 × 100 = 600 cm³
Now we can use the formula for the volume of a sphere to find the radius.
Rearranging the formula, we get:
[tex]r = [\dfrac{3V}{4\pi}]^{(1/3)}[/tex]
Substituting V = 600 cm³, we get:
[tex]r = [\dfrac{3\times600}{4\pi}]^{(1/3)}[/tex]
r ≈ 5.22 cm
Therefore, the radius of a filled balloon is approximately 5.22 cm.
