For this case we have that if Molly spent all the spool ribbon with 12 people, then "r" would be given by the product of 12 for the amount of ribbon that each person received, that is:
[tex]r = 12 * 3\\r = 36 \ft[/tex]
Thus, the spool initially had 36 feet of ribbon.
If Molly also keeps 3 feet of ribbon, then the value of "r" is given by:
[tex]r = 13 * 3\\r = 39 \ ft[/tex]
In this case, the ribbon spool initially had 39 feet of ribbon.
Answer:
[tex]r = 36 \ ft[/tex]shared between 12 people
[tex]r = 39 \ ft[/tex]shared between 12 people and Molly

Express 256^-3/4 as a fraction. Write the fraction in the form a/b, where a and b are positive integers with no common factor greater than 1 .
Answer:
1/64
Step-by-step explanation:
[tex]256^{-\frac{3}{4}}=2^{8(-\frac{3}{4})}=2^{-6}=\dfrac{1}{2^6}=\dfrac{1}{64}[/tex]
256^-3/4 can be converted into a positive fraction by interpreting the negative exponent as a reciprocal and the fractional exponent as a root. It simplifies to 1/(4th root of 256^3), which equals 1/64.
Explanation:To express the numeral 256^-3/4 in the form of a fraction, we first need to understand how negative and fractional exponents work. The number is in the form of a^(-m/n) which is equivalent to the nth root of a^-m or 1/(nth root of a^m). The negative sign in the exponent implies a reciprocal of the number and the fractional exponent denotes a root of the number.
Now applying this understanding to our number which is 256^-3/4. Here, the base a is 256 and the fractions -m/n is -3/4. Therefore, it is equivalent to the 4th root of 256^-3, which can also be written as 1/(4th root of 256^3).
The 4th root of 256 is 4. So, the expression now becomes 1/(4^3), which after simplifying gives us the result 1/64.
So, the expression 256^-3/4 written as a positive fraction is 1/64.

The area of a parking lot is 1710 square meters. A car requires 5 square meters and a bus requires 32 square meters of space. There can be at most 180 vehicles parked at one time. If the cost to park a car is $2.00 and a bus is $6.00, how many buses should be in the lot to maximize income? Please help :(
Answer:
To maximize the income should be 30 buses and 150 cars
Step-by-step explanation:
Let
x-----> the number of cars
y ----> the number of bus
we know that
[tex]5x+32y\leq1,710[/tex] ------> inequality A
[tex]x+y\leq 180[/tex] ----> inequality B
The function of the cost to maximize is equal to
[tex]C=2x+6y[/tex]
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
The vertices of the solution are
(0,0),(0,53),(150,30),(180,0)
Verify
(0,53) ---> [tex]C=2(0)+6(53)=\$318[/tex]
(150,30) ---> [tex]C=2(150)+6(30)=\$480[/tex]
therefore
To maximize the income should be 30 buses and 150 cars
Answer:
Givens
The area of the parking lot is 1710 square meters.A car requires 5 square meters.A bus requires 32 square meters.There can be a maximum of 180 vehicles.The cost for a car is $2.00.The cost for a bus is $6.00.To solve this problem we need to create a table to order all this information and express it as a system of inequations.
Car Bus Total Capcity
Sq. Meters 5c 32b 1710
N° vehicles c b 180
Therefore, the inequalities are
[tex]5c+32b\leq 1710\\c+b\leq 180[/tex]
The expresion which represents the income is
[tex]I=2c+6b[/tex], because a car is $2.00 and a bus is $6.00.
Now, we first need to find the critical points of the solution of the inequality system, which is attached. Observe that the only points that can be a solution is (150,30), because there can't be just car or just buses.
Then, we replace this point in the income expression
[tex]I=2c+6b\\I=2(150)+6(30)=300+180=480[/tex]
Therefore, in order to maximize incomes, we need to park 150 cars and 30 buses, to make $480 income.

Which of the following statements are true?
Answer:
Both graphs have been shifted and flipped
Both graphs have exactly one asymptote
Step-by-step explanation:
Choice A is incorrect since both graphs are not logarithmic functions. The graph of f(x) appears to be an exponential function.
Choice B is also incorrect since both graphs are not exponential functions. The graph of g(x) does not belong to the exponential family since y can take on negative values.

The potential and kinetic energy of a rock thrown into the air and falling back is misunderstood in statement 1. Voting rates are lower in the United States compared to some other democratic countries, and according to Kepler's laws, a satellite speeds up as it approaches its parent body and slows down as it moves away.
Explanation:For the given set of statements:
The statement that 'If a rock is thrown into the air, the increase in the height would increase the rock's kinetic energy, and then the increase in the velocity as it falls to the ground would increase its potential energy.' is False. The potential energy increases with height, not kinetic energy, and when the rock falls, its velocity increases which in turn increases its kinetic energy, not potential energy.The statement that 'Voting rates are higher in the United States than in most democratic industrialized countries, including Sweden and South Korea' is False. These countries are known to have higher voter turnouts compared to the United States.The statement, 'According to Kepler's laws of planetary motion, a satellite increases its speed as it approaches its parent body and decreases its speed as it moves away from the parent body' is True. As a satellite approaches the parent body, gravitational force pulls it in, causing it to speed up and as it travels further from the parent body, it decelerates.

Alice and Will are measuring a liquid solution using graduated cylinders. Alice uses 6.5liters of the liquid solution, and Will uses 4,750milliliters of the liquid solution. What is the ratio of Alice's measurements to Will's measurements? Simplify your answer.
The simplified ratio of Alice's measurements to Will's measurements is 26:19 when both measurements are converted to milliliters.
Explanation:The ratio of Alice's measurements to Will's measurements can be found by converting both measurements to the same units and then simplifying the resulting fraction. Alice's measurement is in liters and Will's measurement is in milliliters. We know that 1 liter equals 1,000 milliliters, so Alice's measurement converted to milliliters is 6.5 liters * 1,000 = 6,500 milliliters.
Therefore, the ratio of Alice's measurement to Will's measurement in milliliters is 6,500:4750. To simplify this ratio, you can find the greatest common divisor (GCD) of the two numbers and divide both numbers by the GCD. In this case, the GCD of 6,500 and 4,750 is 250. Thus, the simplified ratio is 26:19.

The ratio of Alice's measurements to Will's measurements is approximately [tex]\[ \frac{4750 \text{ milliliters}}{1000} = 4.75 \text{ liters} \][/tex]
To compare Alice's measurement to Will's, we need to express them using the same unit. Let's convert Will's measurement from milliliters to liters:
1 liter = 1000 milliliters
So, Will's measurement of 4750 milliliters is equivalent to:
[tex]\[ \frac{4750 \text{ milliliters}}{1000} = 4.75 \text{ liters} \][/tex]
Now, we can compare Alice's and Will's measurements:
Alice's measurement: 6.5 liters
Will's measurement: 4.75 liters
The ratio of Alice's measurements to Will's measurements is:
[tex]\[ \frac{\text{Alice's measurement}}{\text{Will's measurement}} = \frac{6.5}{4.75} \][/tex]
To simplify the ratio, we can multiply both the numerator and the denominator by 4 to get rid of the decimal in the denominator:
[tex]\[ \frac{6.5 \times 4}{4.75 \times 4} = \frac{26}{19} \][/tex]
So, the ratio of Alice's measurements to Will's measurements is [tex]\( \frac{26}{19} \)[/tex].

Which classification best represents a triangle with side lengths 6 cm, 10 cm, and 12 cm? 1. acute, because 62 + 102 < 122 2.acute, because 6 + 10 > 12 3.obtuse, because 62 + 102 < 122 4.obtuse, because 6 + 10 > 12
Answer:
The best represents a triangle is obtuse, because 6 + 10 > 12 ⇒ answer 4
Step-by-step explanation:
* Lets talk about some facts in the triangle
- The triangle is formed when the sum of the lengths of the shortest
two side is greater then the length of the longest side
∵ The lengths of the sides are 6 cm , 10 cm , 12 cm
∵ 6 + 10 > 12
∴ 6 , 10 , 12 are the sides of a triangle
- Two know the type of the triangle use these rules
# The three sides of the triangle have lengths a , b , c where a and b
are the shortest sides means a , b < c, then
- If a² + b² > c² , the triangle is acute triangle (its 3 angles are acute)
- If a² + b² = c² , the triangle is right triangle (the angle opposite to c is a
right angle and the other 2 angles are acute angles)
- If a² + b² < c² , the triangle is obtuse triangle (the angle opposite to c is an
obtuse angle and the other 2 angles are acute angles)
∵ (6)² + (10)² = 36 + 100 = 136
∵ (12)² = 144
∵ 136 < 144
∴ (6)² + (10)² < (12)²
∴ The triangle is obtuse
* The best represents a triangle is obtuse, because 6 + 10 > 12

(a)
The opposite sides of a rectangle are congruent, hence

x = 4
Or
x - 1 = 3 ( add 1 to both sides )
x = 4
(b)
The sum of the 3 angles in a triangle = 180°, hence
3y + 2y + y = 180
6y = 180 ( divide both sides by 6 )
y = 30
Answer:
PART A "4"
PART B "30"
Step-by-step explanation:
PART A
If you refer to my picture below, then you will know that the sides are equal.
The x-1 side is equal to 3 and the x+1 sign is equal to 5. So it best makes sense that 4 is equal to x. That's because x-1 is 3 and x+1 is 5.
PART B
This is tricky. As you know all sides of a triangle add up to 180 degrees. I would divide by 3, but that would be incorrect. Whenever you see these y's, you have to divide by that amount. The y's are there for a reason, so that some sides are bigger than the other. Divide 180 by 6(number of y's). That is 30. This gives you the solution to one y so if it asks you for 2y or 3y, then you would multiply. But it's not. 30 is the answer
