Solve the inequality 2 (m+3) +1 > 23
Answers
Answer:
m>8
Step-by-step explanation:
The first step will be to distribute the 2, so that the equation becomes 2m + 6 + 1 > 23.
From here we should combine like terms, which just means adding 6 and 1, so that the equation is now 2m+7>23. Now, we just subtract 7 on both sides, which brings leave us with 2m > 16.
Lastly dividing by 2 on both sides, the answer is m>8

A line in xy - plane has a slope of 1 and passes through the point (0, 2). Which is an equation of the line?
y = x/2
y = 2x y = x + 2 y = x – 2
Answers
The equation of the line with a slope of 1 passing through the point (0, 2) is y = x + 2.
To verify this, we can substitute the coordinates of the given point (0, 2) into the equation y = x + 2:
2 = 0 + 2
This equation holds true, confirming that the line y = x + 2 passes through the point (0, 2) and has a slope of 1.

For the function F(x)=1/x+1 which of these could be a value of F(x) when x is close to -1
Answers
The value of the function as x tends to -1 is an infinite value.
Given the function f(x) = 1/(x+1)
The value of f(x) as x tends to -1, is gotten by substituting the value of x given into the function as shown:
f(-1) = 1/(-1+1)
f(-1) = 1/0
f(-1) = \(\infty\)
From the result, we can see that the value of the function as x tends to -1 is an infinite value.

What is the minimum point of the graph???
Answers
Answer:
(-2,1)
Step-by-step explanation:
Since this is an upwards opening parabola, the minimum point is at the vertex
We can find the x coordinate of the vertex by
y = 2x^2 +8x +9
where a=2 b =8 and c =9
x = -b/2a
x = -8/(2*2)
= -8/4 = -2
The x coordinate is -2
Now substitute this in to find the y coordinate
y = 2(-2)^2 +8(-2)+9
= 2*4 -16+9
8-16+9
=1
The vertex = (-2,1), which is the minimum point
Answer:
Step-by-step explanation:
y=2x²+8x+9
to find the minimum or maximum point x=-b/2a
x=-8/4=-2
y=2(-2)²+8(-2)+9
y=8-16+9
y=1
minimum point is (-2,-1)
Las dos ruedas traseras de un tractor tienen un perímetro 90 cm mayor que las delanteras. En un camino de 230 metros, las ruedas traseras giran 36 veces menos que las ruedas delanteras. ¿Cuál es el perímetro de las ruedas?
Answers
Sabemos que en un camino de 230 metros, las ruedas delanteras giran 36 veces más que las traseras. Esto significa que la distancia recorrida por las ruedas delanteras es 36 veces mayor que la distancia recorrida por las traseras en ese camino. Por lo tanto:
36(x + 90) = 23000
Resolviendo para x, obtenemos:
x + 90 = 23000/36
x + 90 = 638.89
x = 548.89
Por lo tanto, el perímetro de las ruedas delanteras es de 548.89 cm, y el perímetro de las ruedas traseras es x + 90 = 638.89 cm.

A gull can fly at a speed of 22 miles per hour i.e. equal to 116,160feett/hour and An AMTRAK train travels at 125 miles per hour i.e. equal to 2.1 miles/minute
Given that 1)A gull can fly at a speed of 22 miles per hour and asked to convert its units to foot/hour
2)An AMTRAK train travels at 125 miles per hour and is asked to convert its units to miles/minute
1 mile=5280 feet
22 miles/hour=22 × 5280 foot/hour
22 miles/hour=116,160 foot/hour
1 hour=60 minute
125 miles/hour= 125/60 miles/minutes
125 miles/hour= 2.083 miles/minutes≈ 2.1miles/minutes

Given are Hannah and Becky, who are learning to type on a computer keyboard. Hanna's typing speed is represented by the equation y = 11z. Becky's typing speed is given by the graph as shown in the question.
Now, for Hanna, her typing speed would be -
11 words per minute
For Becky, the slope of the graph will be -
m = (24 - 12)/(2 - 1)
m = 12
12 words per minute
It can be seen easily that Hanna's typing speed is one word fewer than that of Becky's speed.
Therefore, Hanna's typing speed is one word fewer than that of Becky's speed.

Doubt clarification - use comment section.
a variable has a normal distribution with a mean of 100 and a standard deviation of 15. what percent of the data is less than 105? round to the nearest 10th of a percent.
Answers
Rounding to the nearest tenth of a percent, we find that approximately 65.5% of the data is less than 105.
To find the percentage of the data that is less than 105 in a normal distribution with a mean of 100 and a standard deviation of 15, we can use the standard normal distribution table or a statistical calculator.
Using a standard normal distribution table, we need to calculate the z-score for the value 105, which represents the number of standard deviations away from the mean:
z = (x - μ) / σ,
where x is the value (105), μ is the mean (100), and σ is the standard deviation (15).
Substituting the values:
z = (105 - 100) / 15 = 5 / 15 = 1/3.
Looking up the z-score of 1/3 in the standard normal distribution table, we find that it corresponds to approximately 0.6293.
The percentage of the data that is less than 105 can be calculated by converting the z-score to a percentile:
Percentile = (0.5 + 0.5 * erf(z / √2)) * 100,
where erf is the error function.
Substituting the z-score into the formula:
Percentile = (0.5 + 0.5 * erf(1/3 / √2)) * 100 = (0.5 + 0.5 * erf(1/3 / 1.414)) * 100.
Calculating this value gives us approximately 65.48.

Answer:
The hand moved \(\bf \frac{3}{4}\) of a complete turn.
Step-by-step explanation:
The hand moved from 3 to 12, that is, it moved:
12 - 3 = 9 hours
In a clock, 12 hours represent a complete turn.
∴ Using the unitary method:
12 hours ⇒ 1 turn
1 hour ⇒ \(\frac{1}{12}\) turns
9 hours ⇒ \(\frac{1}{12}\) × 9 = \(\frac{9}{12}\)
= \(\bf \frac{3}{4}\) turns (simplified)
∴ The hand moved \(\bf \frac{3}{4}\) of a complete turn.
The answer is \(\boxed{\frac{3}{4}}\).
To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.
Hours covered between 3 and 12 : 12 - 3 = 9Hours covered in a complete turn = 12Fraction of a complete turn it moved : 9/12 = 3/4Find the missing dimension of the figure shown to the right round to the nearest 10th

Having six faces, a rectangular prism is a three-dimensional shape (two at the top and bottom and four are lateral faces). The prism's faces are all rectangular in form. There are three sets of identical faces as a result. A rectangular prism is often referred to as a cuboid because of its form. A rectangular prism may be found in everyday objects like a geometry box, notebooks, diaries, and rooms.
Properties of rectangular prism
There are 6 faces, 12 edges, and 8 vertices on a rectangular prism.The rectangular prism's top and bottom are always rectangles.It has three dimensions, or length, breadth, and height, much like a cuboid.opposing face pairs are identical or coincidentThe lateral sides of a right rectangular prism are rectangle-shaped.The lateral faces of an oblique rectangular prism are parallelograms.Its cross-section is rectangular in shape.It has a perfect cuboid appearance.Formula for volume of rectangular prism is length x width x height
Here,
length = 4 meter , width = 3. 5 meter , height = 1 meter
