Problem page a light bulb consumes 2400 watt-hours per day. how many watt-hours does it consume in 3 days and 6 hours?
Final answer:
The light bulb consumes 7800 watt-hours in 3 days and 6 hours, calculated by summing the daily consumption over three days and additional energy consumed in 6 hours.
Explanation:
To calculate the energy consumption in watt-hours, we first understand that the light bulb consumes 2400 watt-hours in one day. To find out how much it consumes in 3 days and 6 hours, we multiply the daily consumption by the number of days and then add the consumption for the additional 6 hours:
Energy consumed in 3 days = 2400 watt-hours/day imes 3 days = 7200 watt-hours
Energy consumed in 6 hours = (2400 watt-hours/day) / (24 hours/day) imes 6 hours = 600 watt-hours
Adding these two amounts gives us the total energy consumption in the specified time:
Total energy consumption = 7200 watt-hours + 600 watt-hours = 7800 watt-hours
Therefore, the light bulb consumes 7800 watt-hours in 3 days and 6 hours.
4.624 to the nearest 10m
The value of the decimal number 4.624 to the nearest 10 places is 4.6
What is rounding off the numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
Given decimal number is 4.624. The rounding off is:-
4.624 = 4.6 at 10 places
Therefore, the value of the decimal number 4.624 to the nearest 10 places is 4.6

3. Find the slope of the segments AB, CD, and EF.

Answer:
1) AB=7 CD=3 EF=[tex]3\sqrt{5}[/tex] 2) [tex]M_{AB}=\frac{-1}{2},2[/tex] [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] \\ [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] 3) AB not inclined CD not inclined EF 6/5
Step-by-step explanation:
1) We can use the Distance Formula to answer the 1st. question.
But in the first case AB I'd rather doing it intuitively because it is a straight line parallel to the x-axis
AB
A(-4,2) and B(3,2)
In this segment, also parallel we can calculate the length as |-4|+|3|=7 since both have the same y coordinate.
Using the Distance formula to check it:
[tex]D=\sqrt{(3--4)^{2}+(2-2)^{2}}\\D=\sqrt{49}\\D=7[/tex]
CD
C(-4,-1) D(-4,-4)
Similar to the first one but this time with different y coordinates.
The length will be calculated by subtracting the absolute values for y:
|-4|-|-1|=4-1 = 3
Using the Distance formula to check it:
[tex]D=\sqrt{(-4--1)^{2}+(-4--4)^{2}}\\D=\sqrt{9}\\D=3[/tex]
EF
E (1,-1) F(4,-5)
In this case there's no straight line.
So right to the Distance Formula:
[tex]D=\sqrt{(-5-1)^{2}+(4-1)^{2}}\\ D=\sqrt{36+9}\\D=\sqrt{45}\\D=3\sqrt{5}[/tex]
2) To find the Midpoints we need to calculate the Mean of these two points.
AB
A(-4,2) and B(3,2)
[tex]M_{AB} =\frac{-4+3}{2},\frac{2+2}{2}\\M_{AB}=\frac{-1}{2},2[/tex]
CD
C(-4,-1) D(-4,-4)
[tex]M_{CD} =\frac{-4-4}{2} ,\frac{-1-4}{2} \\M_{CD} =(0,\frac{-5}{2})[/tex]
EF
E (1,-1) F(4,-5)
[tex]M_{EF} =\frac{4+1}{2} ,\frac{-1-5}{2} \\ M_{EF} =(\frac{5}{2}-3)[/tex]
3) To find the Slope let's calculate the quotient of a difference between y-coordinates over x-coordinates of two given points.
[tex]m_{AB}=\frac{2-2}{3--4}=\frac{0}{7}=0[/tex]
AB is not inclined.
CD
C(-4,-1) D(-4,-4)
[tex]m_{CD}=\frac{-4--1}{-4--4}=\frac{-3}{-4+4}=\frac{-3}{0}[/tex]
Not Defined for all Real Set of Numbers
The line CD is not inclined.
EF
E(1,-1) F(4,-5)
[tex]m_{EF}=\frac{-5-1}{4--1}=\frac{6}{5}[/tex]
The line EF has a slope of 6/5

The length of a side of an equilateral triangle is 12. find the length of the altitude
Final answer:
To calculate the altitude of an equilateral triangle with side length 12, divide the side by 2 and multiply by [tex]\(\sqrt{3}\)[/tex] giving an altitude of approximately 10.3923 units.
Explanation:
To find the length of the altitude of an equilateral triangle with a side length of 12, you can use the Pythagorean theorem. The altitude of the equilateral triangle creates two 30-60-90 right triangles. The altitude is the longer leg in this case, and the side of the triangle is the hypotenuse. In a 30-60-90 triangle, the longer leg (altitude) is [tex]\(\sqrt{3}\)[/tex]times the shorter leg (half of the side of the triangle).
First, divide the side of 12 into two to get the shorter leg of the right triangle, which is 6. Then, multiply 6 by \(\sqrt{3}\) to find the length of the altitude. This results in:
[tex]\(6 \times \sqrt{3} = 6\sqrt{3} \approx 10.3923\)[/tex]
Therefore, the altitude of the equilateral triangle is approximately 10.3923 units long.

The Tony age and Howard age be 36 and 33 respectively.
It is required to find the age of tony.
What is age?The amount of time during which someone or something has lived or existed. The length of time that a person has lived or a thing has existed.
Given:
Let Howard age=x
Tony age=x+3
Before 5 year we have,
Howard age=x-5,
Tony age=x+4-5=x-1
Some of there age=59
According to given question we have,
x-5+x-1=59
2x-6=59
2x=65
X=65/2
x=32.5
The age can't be fraction or decimal so we take 33.
Howard age=33
Tony age=33+3=36
Therefore, the Tony age and Howard age be 36 and 33 respectively.

B.–5 and –1
C.–1 and 4
D.0 and 4
Answer
C.–1 and 4
Explanation
Solving the equations y = –x² + 4x and y = x – 4
–x² + 4x = x – 4
x² - 4x + x = 4
x² - 3x = 4
x² - 3x + (3/2)² = 4 + (3/2)²
(x - 3/2)² = 4 + 9/4
= 6.25
x - 3/2 = √6.25 or x - 3/2 = -√6.25
x = 2.5 + 1.5 x = -2.5 + 1.5

Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.
Let x represent the number of pounds of lettuce that Kendra buys. Let y represent the number of pounds of tomatoes that Kendra buys.
Which inequality represents this situation?
A. 2.25x+2.65y>8
B. 2.25x+2.65y<8
C. 2.25x+2.65y≤8
D.2.25x+2.65y≥8
Answer: The correct option is
(D) [tex]2.25x+2.65y\geq8.[/tex]
Step-by-step explanation: Given that Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.
x represent the number of pounds of lettuce that Kendra buys and y represent the number of pounds of tomatoes that Kendra buys.
We are to select the inequality that represents the situation.
We have
total amount of money that Kendra spends on lettuce is given by
[tex]a_l=2.5\times x=2.5x[/tex]
and the total amount of money that she spends on tomatoes is
[tex]a_t=2.65\times y=2.65y.[/tex]
Therefore, the inequality can be written as
[tex]a_l+a_t\geq 8\\\\\Rightarrow 2.25x+2.65y\geq8.[/tex]
Thus, option (D) is CORRECT.
