The leg of a right triangle is 3 units and the hypotenuse is 11 units. What is the length, in units, of the other leg of the triangle? HURRY PLEASE!!!
a
112 units
b
square root 112 units
c
130 units
d
square root 130 units
The correct option is (b) square root 112 units
Step-by-step explanation:By using Pythagoras theorem,
a² + b² = c²where a & b = legs of triangle and c = hypotenuse
Hence:
3² + b² = 11²9 + b² = 121b² = 121 - 9b² = 112b = √112A manufacturer makes bags of popcorn and bags of potato chips. The average weight of a bag of popcorn is supposed to be 3.03 ounces with an allowable deviation of 0.02 ounces. The average weight of a bag of potato chips is supposed to be 5.08 ounces with an allowable deviation of 0.05 ounces. A factory worker randomly selects a bag of popcorn from the assembly line and it has a weight of 3.06 ounces. Then the worker randomly selects a bag of potato chips from the assembly line and it has a weight of 5.03 ounces. Which description closely matches the findings on the assembly line?
Answer:
The weight of the popcorn is off but the potato chips are safe. Simply determine whether each value is within the limit of deviation from eachother.
Question 6(Multiple Choice Worth 2 points)

At a restaurant, hot chocolate can be purchased in three different cup sizes. A 12-ounce cup costs $1.97, a 16-ounce cup costs $2.62, and a 20-ounce cup costs $3.27.
Which statement is true based on the given description?
O The description shows a linear relationship, but not a proportional relationship.
O The description shows a linear relationship and a proportional relationship.
O The description does not show a linear relationship or a proportional relationship.
O The description shows a proportional relationship, but not a linear relationship
We need to know about linear and proportional relationship to solve this problem. Statement 2 is true, the description shows a linear relationship and a proportional relationship.
Linear relationship is a relationship between two variables where if one increases the other increases or if one decreases the other decreases. The varibales in a linear relationship form a straight line on graph. Proportional relationship is the relationship between two variables where the ratio between pairs of different data always remains constant. In the given question, a 12 ounce cup costs $1.97, a 16 ounce cup costs $2.62 and a 20 ounce cup costs $3.27. The price of each cup increases with increase in capacity of the cup, so we can say that the cup capacity and price have a linear relationship. The ratio between each pair can be given by
12/1.97=6.10
16/2.62=6.10
20/3.27=6.10
The ratios between every pair is same, so it is a proportional relationship.
Thus we found that the description shows a linear relationship and a proportional relationship between the cup capacity and it's price, statement 2 is the right option.

6) On a map scale 1cm to 250m the area of
a car park is 3cm². What is the actual
area of the care park in hectares? (1 hectare=10,000m^2)
The actual area of the care park in hectares is 18.75
As per the known fact, ratio of measurement on scale is equal to the ratio of measurement in real. So, writing the equation first -
Area of car park = 3 cm²
Keep the value of 1 cm in the above mentioned equation.
Area of car park = 3 × (250)²
Taking square
Area of car park = 3 × 62,500
Performing multiplication
Area of car park = 1,87,500 m²
Converting the area in hectares
10,000 m² = 1 hectare
1,87,500 m² = (1 ÷ 10,000) × 1,87,500
1,87,500 m² = 18.75 hectares.
Therefore, the actual area of the care park is 18.75 hectares.

For logarithmic equation 1/2 log x + log 4 = 2, the value of x is 34,040.25
How can a logarithmic equation be solved?Step 1: Using exponentiation principles, isolate a logarithmic expression (with the same base) on both sides of the equation.
Step 2: balance the arguments.
Step 3: Solve the resultant equation.
Step 4: Double-check your answers.
Given,
1/2 log x + log 4 = 2
log x^(1/2) + log 4 = 2
using logₐ(m.n) = logₐ(m) + logₐ(n)
log e (4 (x^1/2)) = 2
e² = 4x^(1/2)
7.38 = 4√x
Squaring on both sides -

log₃9
The value of the expression log₃9 is 2.
The logarithmic function is the inverse of the exponential function. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x.
Log a to the base b can be written as- log a/ log b.
Moreover, log [tex]a^{k}[/tex]= k log a, for all non negative values of a
Here, we are given a logarithmic expression- log₃9
We can expand this as-

¿Qué es una recta numérica?Una recta numérica es una herramienta gráfica de las matemáticas que nos sirve para ubicar números positivos y negativos en un gráfico con el objetivo de organizarlos con respecto al número cero.
¿Cómo funcionan las líneas de tiempo con años Antes de Cristo y Después de Cristo?Las líneas de tiempo con fechas Antes y Después de Cristo se pueden asociar a una recta numérica debido a que los años Antes de Cristo se ubican en la parte negativa de la gráfica (a la izquierda del cero) y los número Después de Cristo se ubican en la parte positiva (a la derecha del cero).
¿Cuál es el año de nacimiento de su hijo?Para identificar el año de nacimiento del hijo debemos tener en cuenta que las fechas que se ubican en la zona negativa de la recta numérica aumentan de forma invertida, es decir que si su hijo nació 28 años después de ella se debe restar este número a su fecha de nacimiento como se muestra a continuación:

㏑ [tex](\frac{ac^{\frac{1}{3} }}{b^2} )[/tex]
What is a natural logarithm?A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.
The power to which e would need to be raised in order to equal x is the natural logarithm of x.
For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.
Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.
We have been asked to express ln a-2 ln b+1/3 ln c as a single natural logarithm.
