Central subs made 27 sandwiches using 12 pounds of turkey, how much turkey was used per sandwich?
Answer: [tex]\frac{4}{9}[/tex] lbs of turkey
Step-by-step explanation:
hey there,
< Since we know 27 sandwiches = 12 lbs, then let's make a ratio table.
27 sandwiches = 12 lbs
1 sandwich = ? lbs
The way you solve a ratio table is multiply the two amounts that cross each other that do not include the thing we are trying to find. Here, it would be 12 lbs x 1 sandwich, as they are right across from each other and there is no "?" within either of those two. 12 x 1 = 12. Now, divide by the last amount left that we haven't touched yet (27 sandwiches).
12 ÷ 27 = [tex]\frac{12}{27}[/tex] = [tex]\frac{4}{9}[/tex] lbs of turkey or you can change it to a decimal so it would be 0.44 lbs (not precise so it's better to use a fraction). >
Hope this helped! Feel free to ask anything else if you still have questions.
Answer:
4/9 lbs per sandwich
Step-by-step explanation:
We want turkey per sandwich
12 lbs turkey/ 27 sandwiches
4/9 lbs per sandwich
solve the equation below
for the indicated variable
1/3ab^2=6 (solve for a)
Answer:
a=18/b2
Step-by-step explanation:
The required equation for the indicated variable is a = 18/b² which is solved for a.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given the equation for the indicated variable as
⇒ 1/3ab² = 6
Multiply by 3 both sides of the above equation,
⇒ ab² = 6×3
⇒ ab² = 18
Divide by b² into both sides of the equation, and we get
⇒ a = 18/b²
Therefore, the required equation for the indicated variable is a = 18/b².

Write 7.35 as a mixed number.
Answer:
7 7/20 is the answer.
Answer: 7 7/20
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
7.35=7.35 / 1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 100
7.35/ 1 × 100/ 100=735 / 100
Find the Greatest Common Factor (GCF) of 735 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5
735 ÷ 5 = 147
100 ÷ 5 = 20
Divide 147/ 20 = 7 7/20
To which subset(s) of real numbers does the number -4 belong? Choose all that apply Irrational numbers Integers Whole numbers Natural numbers Rational numbers
Answer:
The answer is: Integers, and Rational Numbers.
Step-by-step explanation:
the number -4 belongs to the subsets of real numbers: Integers and Rational numbers.
The number -4 belongs to the following subsets of real numbers:
1. Integers: Integers include all positive and negative whole numbers, as well as zero. Since -4 is a negative whole number, it is an integer.
2. Whole numbers: Whole numbers include all non-negative integers. Since -4 is negative, it is not a whole number.
3. Natural numbers: Natural numbers include all positive integers. Since -4 is negative, it is not a natural number.
4. Rational numbers: Rational numbers include all numbers that can be expressed as a ratio of two integers, where the denominator is not zero. -4 can be expressed as -4/1, where -4 is an integer and 1 is also an integer. Therefore, -4 is a rational number.
In conclusion, the number -4 belongs to the subsets of real numbers: Integers and Rational numbers.

find all values of c such that the domain of the following function is the set of all real numbers
f(x) = (x + 7) / (x^2 + 2cx + 14)
Answer:
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
Step-by-step explanation:
For the function to have a domain of all reals, the denominator cannot have a value of zero. x^2 + 2cx + 14 will not have zero as a root if it has no real solutions. A quadratic equation has no solutions when the discriminant is negative.
b^2 - 4ac < 0
(2c)^2 - 4(1)(14) < 0
4c^2 - 56 < 0
4c^2 < 56
c^2 < 14
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
The domain of the function, f(x) = (x + 7) / (x^2 + 2cx + 14) is the set of all real numbers for the value of c as [tex]-\sqrt{14} < c < \sqrt{14}[/tex] .
Domain of a function are the values that a function can take that is the set of all possible inputs.
Given the following function:
[tex]f(x)=\dfrac{x+7}{x^2+2cx+14}[/tex]
For the real number domain of the given function, the denominator must be a non-zero term. Because, if the denominator is zero then the function will result in an undefined number which does not lie in the real number domain.
For denominator to be non zero, we have to find the value of x which is not the solution of the equation of denominator.
x²+2cx+14≠0
Such value of x can be determined using discriminant.
d<0, then no real solution exists.
d=b²-4ac
Here a=1, b=2c, c=14
d=4c²-4x14
d=4c²-56
d<0
4c²-56<0
4c²<56
c²<14
[tex]-\sqrt{14} < c < \sqrt{14}[/tex]
Thus, [tex]-\sqrt{14} < c < \sqrt{14}[/tex] is such that the domain of the function is the set of all real numbers.

For the constant function v(x) = 1, which statement describes the additive and multiplicative inverses? Both inverses are equal to v(x). Neither inverse is equal to v(x). The additive inverse is equal to v(x), but the multiplicative inverse is not. The multiplicative inverse is equal to v(x), but the additive inverse is not.
Answer:
The multiplicative inverse is equal to v(x), but the additive inverse is not.
Step-by-step explanation:
The multiplicative inverse is equals to v(x) but the additive inverse is not.
What is additive inverse?Additive inverse is a number which on getting added to the original number results in zero.
For example, 5 - 5 = 0
⇒ -5 is the additive inverse of 5.
What is multiplicative inverse?Multiplicative inverse of a number is a value which when multiplied by the original number results in 1.
For example
[tex]5 (\frac{1}{5} )= 1[/tex]
⇒ [tex]\frac{1}{5}[/tex] is the multiplicative inverse of 5.
According to the given question.
We have a function
v(x) = 1
Let the additive inverse of 1 is x.
⇒ 1 + x = 0
⇒ x = -1.
Hence, the additive inverse of 1 is -1.
Let the multiplicative inverse of 1 is y.
⇒ 1 × y = 1
⇒ y = 1/1
⇒ y = 1
Hence, the multiplicative inverse of 1 is 1.
From the above calculation we can see that, the multiplicative inverse is equals to v(x) but the additive inverse is not.
Thus last option is correct.

¿De que manera las propiedades de las operaciones de los números racionales las podemos emplear en la estimación de presupuesto?
Answer:
La pregunta no está completa. Explicaré las propiedades de funcionamiento de los números racionales.
Explanation:
Las principales propiedades de los números racionales son:
- Propiedad de cierre
- Propiedad de conmutatividad
- Propiedad asociativa
- Propiedad distributiva
La propiedad de cierre establece que para dos números racionales cualesquiera xey, x + y, x-y, x * y, y x / y también será un número racional.
La propiedad de conmutatividad establece que para dos números racionales cualesquiera xey, x + y = x + y; x - y ≠ y - x; x * y = y * x; x / y ≠ y / x.
La propiedad asociativa establece que para cualesquiera tres números racionales dados x, y y z, (x + y) + zyx + (y + z) son iguales.
La propiedad distributiva establece que para tres números cualesquiera x, y y z, x × (y + z) = (x × y) + (x × z).

The formula for the distance traveled over time ttt and at an average speed vvv is v\cdot tv⋅tv, dot, t. Amit ran for 404040 minutes at a speed of about 555 kilometers per hour. What calculation will give us the estimated distance Amit ran in kilometers?
Answer:
5 x 40/60
Step-by-step explanation:
The distance Amit ran will be 3.34 kilometers in 40 minutes.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Distance is defined as the length between the two points.
It is given that the distance traveled over time t and at an average speed is s. Amit ran for 40 minutes at a speed of about 5 kilometers per hour.
The distance will be calculated by using the speed formula:-
Speed = Distance / time
Convert the formula to calculate distance.
Distance = Speed x Time
Distance = 5 x ( 40/60 )
40/ 60 is the time in hours.
The distance will be calculated as:-
Distance = 10 / 3
Distance = 3.34 kilometers
Therefore, the distance Amit ran will be 3.34 kilometers in 40 minutes.

Make t the subject of the formula 2(d – t) = 4t + 7
Step-by-step explanation:
2(d-t)=4t +7
open the bracket
2d - 2t =4t +7
collect like terms
2d-7=4t +2t
2d-7=6t
divide both sides by 6
2d-t/6=6t/6
T=2d-t/6
Answer:
t = (2d-7)/6
Step-by-step explanation:
2(d – t) = 4t + 7
Distribute
2d-2t=4t+7
Add 2t to each side
2d-2t+2t=4t+2t+7
2d = 6t+7
Subtract 7 from each side
2d-7 = 6t
Divide by 6
(2d-7)/6 = t
