Step-by-step explanation:
Subtracts those with same units but given that 40" is lower than 50", we need to borrow from 50' which can be read as 50 minutes.
40" is read as 40 seconds. Since 1 minute has 60 seconds, we have:
40" + 60" = 100" and
50' - 1' = 49'
These values will yield 60° 49' 100"
Now that the upper values are higher than the one below, we can now perform the operation:
60° - 30° = 30°
49' - 40' = 9'
100" - 50" = 50"

decompose x^2+4x-3/x-2
Answer:
[tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]
Step-by-step explanation:
The given equation is :
[tex]x^2+\dfrac{4x-3}{x-2}[/tex]
We need to decompose this equation.
We have,
[tex]x^2+\dfrac{4x-3}{x-2}\\\\=\dfrac{x^2(x-2)+4x-3}{x-2}\\\\=\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]
So, [tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex] is the decomposed form of the given expression.

John rode his bicycle to school and back home. The distance from his home to school is 1.30 miles. What is the approximate number of kilometers that John rode? (1.00 kilometers = 0.62 miles)
Answer:
4.1935483871km
Step-by-step explanation:
Distance to and back = 1.3 miles *2 = 2.6miles
To convert kilometres to miles, multiply by 0.62. Therefore, to convert from miles to kilometres, divide by 0.62.
2.6/0.62=4.1935483871km
I heard that you might have to increase your prices by 12%. If I normally pay $45 per order, how much would my order be if the price increase happens?
Answer:
If the price increase happens, your order would be $50.4.
Step-by-step explanation:
To be able to determine how much would the order be if the price increase happens, first you have to calculate 12% of the normal price per order:
$45*12%=$5.4
Then, you have to add $5.4 that is the amount of the increase plus the normal price per order:
$5.4+$45=$50.4
According to this, the answer is that if the price increase happens, your order would be $50.4.

= 8564.856608.
Helpppppppp i really need help
Answer:
Step-by-step explanation:
1). Unit rate = slope of the graph at x =1
Unit rate means value of y at x = 1
From the graph of the given function,
(1, 2) is the point which defines the unit rate.
2). Table (1),
If the data shows the proportional relationship,
[tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]
[tex]\frac{2}{6}=\frac{1}{3}[/tex]
[tex]\frac{1}{3}= \frac{1}{3}[/tex]
Therefore, table (1) represents the proportional relationship.
Table (2),
If the data given in table is proportional,
[tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]
[tex]\frac{8}{5}=\frac{4}{2}[/tex]
[tex]\frac{8}{5}=\frac{2}{1}[/tex]
Which is not true.
Therefore, table (2) doesn't show the proportional relationship.
A type of battery-operated led lights has a known mean lifetime 7.9 hours with standard deviation 0.5. Assuming that the lifetimes of these led lights have a nearly symmetric/bell-curve distribution, find the percent (%) of these led lights having lifetime between 7.9 and 8.9 hours.
Answer:
47.5% of these led lights have lifetime between 7.9 and 8.9 hours.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.9 hours
Standard deviation = 0.5 hours
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
Lifetime between 7.9 and 8.9 hours:
7.9 hours is the mean.
8.9 = 7.9 + 2*0.5
So 8.9 hours is two standard deviations above the mean.
Of the 50% of the measures that are above the mean, 95% are between the mean of 7.9 and two standard deviations above the mean(8.9). So
0.5*0.95 = 0.475
47.5% of these led lights have lifetime between 7.9 and 8.9 hours.

An Air Conditioner uses 850 Watts of electricity and local emissions from electricity produce 1.37 pounds of CO2 per kWh. If you open a window instead of using the AC for 6 hours, how many pounds of CO2 would you keep from entering the atmosphere?
Answer: 6,987,000 pounds fo CO₂ per kWh.
Step-by-step explanation: Quilowatt-hour (kWh) is a unit of energy that measures the amount of energy expended in 1 hour.
The AC uses 850 Watts, which in kW is 850,000 kW
If you leave the AC on for 6 hours, it will consume
850,000(6) = 5,100,000 kWh
Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:
1.37 [tex]\frac{pounds}{kWh}[/tex].(5,100,000kWh) = 6,987,000 pounds
If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.
The value of y varies directly with x, and y
Find y when x = 2.4.
7.2 when x = 1.6.
Answer:
Step-by-step explanation:
Select the correct answer. Consider functions f and g.
WILL MARK BRAINLIEST Determine if each of the following are direct (D), Inverse (I), or neither (N). On the first blank, write the letter that corresponds with the variations. In the second blank, write the constant of variations. If the function doesn't have a constant of variations than leave the second blank empty. (PLEASE REFER TO PICTURE)
Answer:
A is neither, B is direct, and C is inverse
Step-by-step explanation
In B, as x increases y also increases, in C as x increases y decreases, and in A it's neither because it's not one line (if you graphed it you would understand what I mean). Though I have no idea what is constant of variations.
