To fill the tank, multiply 2/5 by the tank's capacity of 20.25 gallons.
Explanation:To find the number of gallons it will take to fill the tank, we need to determine how much more fuel is needed to make the tank full. We can do this by subtracting the current amount of fuel in the tank from its full capacity. The tank is 3/5 full, so the remaining amount of fuel needed to fill the tank is 2/5 of its capacity. Since the capacity of the tank is given as 20.25 gallons, we can calculate the number of gallons needed to fill the tank by multiplying 2/5 by 20.25:
2/5 * 20.25 = 8.1 gallons
Therefore, it will take 8.1 gallons to fill the tank.

Richard Lens receives a 3.5% commission for selling cleaning supplies. What is his commission on sales of $122,591?
Answer:
$4,290.69
------------------------------------------------------------------------------------------------------
- To find the commission, just convert the percentage into a decimal (divide by 100) and multiply it by the sales.
3.5% = 0.035
122,591 x 0.035 = $4,290.69
Answer:
Richard Lens received a commission of $4,290.685 on a sale of $122,591.
Step-by-step explanation:
We are given the following information in the question:
Total sale made = $122,591
Commission received by Richard = 3.5%
Amount of commission relieved =
Formula:
[tex]\displaystyle\frac{\text{Percentage of Commission recived}}{100}\times \text{Total sales}[/tex]
= [tex]\displaystyle\frac{3.5}{100}\times 122591[/tex]
= $4290.685
Thus, Richard Lens received a commission of $4,290.685 on a sale of $122,591.

A 48ft wire is cut into 3 pieces. The 2nd is three times as long as the first piece. The third piece is 4 times as long as the second piece. How long is each piece?
Answer:
3,9,and 36
Step-by-step explanation:
small=x
median=3x
big=12x
x+3x+12x=48
16x=48
x=3
3=small
3*3=9 (median)
9*4=36(big)
3+9+36 = 48
The problem is solved by setting up and solving an equation where 'x' represents the length of the first piece. The three pieces of the wire measure 3ft, 9ft, and 36ft respectively.
Explanation:The question is about finding the length of each piece of a 48ft wire when it's divided into 3 pieces, with each piece having a specific relative length. Let's denote the length of the first piece as 'x'. According to the problem, the second piece is three times as long as the first one, so it's '3x', and the third is four times as long as the second, so it's '4*3x', which simplifies to '12x'.
Combining all these pieces, we get the total length of the wire: x + 3x + 12x = 48ft. This simplifies to 16x = 48ft. Finally, solving for 'x', we find that x = 48ft / 16 = 3ft. Therefore, the three pieces of the wire measure 3ft, 9ft, and 36ft respectively.

What is the distance from the sun to mercury
Answer:
58,000,000 km
Step-by-step explanation:
the hair thing is just to throw you off
The average distance from the Sun to the planet Mercury is approximately 58 million kilometers, which also translates to 0.39 astronomical units (AU). Mercury's orbit varies from 46 million kilometers at its closest to 70 million kilometers at its farthest from the Sun due to its elliptical orbit.
Explanation:Distance from the Sun to Mercury
The average distance from the Sun to Mercury is about 58 million kilometers. This distance is known as the semimajor axis of Mercury's orbit. Since Mercury's orbit has a high eccentricity of 0.206, its actual distance from the Sun can vary significantly. The closest point, or perihelion, is about 46 million kilometers, and the farthest point, or aphelion, is about 70 million kilometers. The concept of astronomical unit (AU) is used as a standard measure within the solar system, defined as the average Earth-Sun distance, which is about 150 million kilometers or 1 AU. Consequently, Mercury's average distance from the Sun can also be expressed as 0.39 AU.

The length of a rectangle is 2 km less than 3 times the width. If the perimeter is 68 km,What is the length of the rectangle
Answer:
The length of the rectangle is 25 km
Step-by-step explanation:
Let
x ----> the length of rectangle
y ----> the width of rectangle
we know that
The perimeter of rectangle is
[tex]P=2(x+y)[/tex]
we have
[tex]P=68\ km[/tex]
so
[tex]68=2(x+y)[/tex]

[tex]34=(x+y)[/tex]---- > equation A
[tex]x=3y-2[/tex] ---> equation B
substitute equation B in equation A and solve for y

[tex]4y=34+2[/tex]
[tex]4y=36[/tex]
[tex]y=9\ km[/tex]

Nine more than seven times a number (x) is at least thirty.
Inequality:
The solution to the inequality is
Answer:
7x + 9 ≥ 30
x ≥ 3
Step-by-step explanation:
7x + 9 ≥ 30
7x ≥ 21
x ≥ 3
Final answer:
The inequality 7x + 9 ≥ 30 represents the description given, and the solution is x ≥ 3, meaning any number greater than or equal to 3 satisfies the inequality.
Explanation:
The inequality that represents the description 'nine more than seven times a number (x) is at least thirty' is written as 7x + 9 ≥ 30.
To solve this inequality:
Subtract 9 from both sides of the inequality: 7x ≥ 21.Divide both sides by 7 to isolate x: x ≥ 3.Therefore, the solution to the inequality is that x must be a number greater than or equal to 3.

a. What percent of people earn less than $40000?

variable X =−50000

~N(0,1).
( < 40000) = ( <
40000 − 50000
20000 ) = ( < −0.5) = (−0.5) = 0.3085375.
Here Φ(x) denotes the cumulative distribution function of a standard normal distribution.
Answer: 31%.
b. What percent of people earn between $45000 and $65000?
Solution:
(45000 < < 65000) = (
45000 − 50000
20000 < <
65000 − 50000
20000 ) = (−0.25 < < 0.75)
= (0.75) − (−0.25) = 0.7733726 − 0.4012937 = 0.3720789.
Answer: 37%.
c. What percent of people earn more than $70000?
Solution:
( > 70000) = ( >
70000 − 50000
20000 ) = ( > 1) = 0.8413447.
Answer: 84%.
By converting the salary amounts to Z-scores and checking a standard normal distribution table, the percentages of people earning less than $40,000, between $45,000 and $65,000, and more than $70,000 are approximately 30.85%, 37.21%, and 15.87%, respectively.
Explanation:In this question, we are dealing with what is known as a 'normal distribution' in statistics. The properties of a normal distribution allow us to calculate the percentages requested. First, we need to convert each salary to a 'Z-score'. A z-score will tell us how many standard deviations away from the mean the salary lies.
a) For $40,000, the Z-score will be (40000-50000)/20000, yielding -0.5. Looking up this Z-score in a standard normal distribution table, or using a calculator equipped with normal distribution functions, we find that roughly 30.85% of employees would earn less than $40,000.
b) For the range $45,000 to $65,000: the Z-scores will be -0.25 and 0.75 respectively. These correspond to about 40.13% and 77.34%. The percentage of people earning between these amounts would be 77.34% - 40.13% = 37.21%.
c) For over $70,000: the Z-score is 1.0 which corresponds to around 84.13%. Therefore, the percentage earning more than $70,000 is 100% - 84.13% = 15.87%

a football team lost 5 yards on each of 3 plays. Explain how you could use a number line to find the team's change in the field position after the 3 plays
You would start out at in the middle of a number line (horizontal). After the first play, you would move to the left on the line 5 spots (to simulate 5 yards lost) and then make a dot to show your new position. You would do the same thing for the next two plays, moving 5 spots to the left each play and creating a new starting point each time. The total spots moved after the 3 plays is 15 spots to the left.
