Answer:
Las siguientes desigualdades expresan la condición real de la medida:
[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.
O de manera más rigurosa:
[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex], donde [tex]\epsilon[/tex] es el sesgo no captado por el observador.
Step-by-step explanation:
La graduación de la regla es la resolución visual de la medida, equivalente a 0.1 centímetros. Entonces, la medida obtenida de 5.3 centímetros es equivalente a un valor [tex]x[/tex] mayor que 5.2 centímetros y menor que 5.4 centímetros. Matemáticamente hablando, tenemos la siguiente desigualdad:
[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.
De manera más rigurosa, podemos describir el valor medido más un sesgo no captado por el observador ([tex]\epsilon[/tex]), medido en centímetros, dentro del intervalo citado:
[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex]

y+1=3x+9
y=3x+8
The equation of the line passes through the point (-3, -1)(and (-4, -4) is y=3x+8.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line passes through the points (-3, -1)(and (-4, -4)
The slope will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( -4 + 1 ) / ( -4 + 3 )
Slope = 3
The y-intercept is calculated as,
y = 3x + c
-1 = 3 x -3 + c
c = 8
The equation of the line will be,
y=3x+8

According to Teo's bread recipe, he should bake the bread at ° for 30 minutes. His oven measures temperature in °F. To what temperature, in °, should he set his oven? Rewrite the formula C= 59 F-32 to find the Fahrenheit temperature that is equal to °C.
Answer:
[tex]F = \frac{9}{5}(C + 32)[/tex]
Step-by-step explanation:
Given
[tex]C = \frac{5}{9}F - 32[/tex]
First, we need to solve for F
[tex]C = \frac{5}{9}F - 32[/tex]
Add 32 to both sides
[tex]C + 32 = \frac{5}{9}F - 32 + 32[/tex]
[tex]C + 32 = \frac{5}{9}F[/tex]
Multiply both sides by [tex]\frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = \frac{5}{9}F * \frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = F[/tex]
[tex]F = \frac{9}{5} * (C + 32)[/tex]
[tex]F = \frac{9}{5}(C + 32)[/tex]
Next, is to determine the temperature in degrees Fahrenheit
However, this is not stated the degree Celsius equivalent is not stated in your question.
So, I'll assume a value for it.
Assume that C = 23
Substitute 23 for C in [tex]F = \frac{9}{5}(C + 32)[/tex]
[tex]F = \frac{9}{5}(23+ 32)[/tex]
[tex]F = \frac{9}{5}(55}[/tex]
[tex]F = 9 * 11[/tex]
[tex]F = 99[/tex]

Answer:
x = 10
x = 27
Step-by-step explanation:
53 and 5x + 3 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
53 = 5x + 3
subtract 3 from both sides of the equation
53 - 3 = 5x + 3 - 3
50 = 5x
divide both sides of the equation by 5
50/5 = 5x/5
10 = x
82 and 3x + 1 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
82 = 3x + 1
subtract 1 from both sides of the equation
82 - 1 = 3x
81 = 3x
divide both sides of the equation by 3
81/3 = 3x/3
27 = x

A scale drawing of an office space uses a scale of 2 in. : 3 yd. The scale drawing has an area of 12 square inches. What is the area of the actual office space?
Answer: The area of the actual office space = 18 sq. yards
Step-by-step explanation:
Formula : Image length = Scale factor x original length
Given: A scale drawing of an office space uses a scale of 2 in. : 3 yd.
i.e. scale factor = [tex]\dfrac23[/tex]
The scale drawing has an area of 12 square inches.
i.e. [tex]\text{12 sq. inches}=\dfrac23\times\text{area of the actual office space }[/tex]
[tex]\Rightarrow\ \text{Area of actual office space}=\dfrac{3}{2}\times12=18\text{ sq. yards}[/tex]

Nick has two pieces of twine.One 20 feet long and the other one 12 feet long.If he wants cut them up to produce many pieces of twine that are all of the same length with no twine left over what is the greatest length in feet that he can make them?
Answer:
The greatest length in feet the twines can be cut into with no twine left over is 4 feet
Step-by-step explanation:
To determine the greatest length a 20 feet long twine and a 12 feet long twine can be cut into such that the pieces are of the same length and no twine is left over, we will find the highest number that can be used to divide 20 and 12 with no remainder. Hence, we will find the Highest common factor (HCF) of 20 and 12.
Factors of 20 are: 1,2,4,5,10, and 20
and the factors of 12 are: 1,2,3,4,6, and 12
The highest common factors of 20 and 12 is 4.
Hence, the greatest length in feet the twines can be cut into with no twine left over is 4 feet.
Ivan works as a tutor for $8 an hour and as a waiter for $7 an hour. This month, he worked a combined total of 89 hours at his two jobs. Let t be the number of hours Ivan worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.
Answer:
t+623
Step-by-step explanation:
If t is the number of hours Ivan worked as a tutor this month, you can say that the number of hours that Ivan worked as a waiter would be the result of subtracting the amount of hours he worked as a tutor this month from the combined total of hours he worked, which is:
89-t
After this, you can say that the combined total dollar amount Ivan earned this month is the result of adding up what he earned as a tutor plus the amount he earned as a waiter which is equal to 89-t. So, you would have:
8t+7*(89-t)
=8t+623-7t
=t+623
This means that the expression for the combined total dollar amount he earned this month is: t+623
Is 80/10 equal to -8
Answer: No
Step-by-step explanation: Two positives divided never make a negative
Answer:
No, 80/10 turned into a whole number is 8, not -8.
Step-by-step explanation:
To get a whole (1), you need to have 10/10. Since we have 10/10 8 times (80/10) this means we get a whole number of 8, not -8. Therefore, its false. 80/10 is NOT equal to -8

Emmanuel is starting a cycling training program. He will start cycling a short distance and increase his distance over time. Emmanuel will cycle 5 miles during the first week and increase his distance by 2 miles each week for 12 weeks.
Answer:
29milesStep-by-step explanation:
We can use the equation of a straight line as a concept to solve this problem
that is y=mx+c
at the end of the 12 weeks we can estimate the total distance that Emmanuel must have covered.
Given data.
the total distance is y
the number of weeks is x
and the starting distance is c (based on the equation of line)
starting distance= 5 miles,
increment = 2miles each week
number of weeks =12
substituting we have
y=2(12)+5
y=24+5
y=29miles
the total distance covered after 12 weeks is 29miles
