Water is added or drained from a tank each day. The first day, 910 of a gallon is added to the empty tank. The second day, 710 of a gallon is drained from the tank. The third day, 810 of a gallon is added to the tank. The fourth day, 610 of a gallon is drained from the tank. The amount of water in the tank after 15 days is given by 910+(−710)+810+(−610)+⋯+310+(−110)+210 9 10 + ( − 7 10 ) + 8 10 + ( − 6 10 ) + ⋯ + 3 10 + ( − 1 10 ) + 2 10 . How much water is in the tank after 15 days? Write your answer as a decimal. gallon(s)
Answer:
The quantity of water in the tank after 15 days is 1610.0 gallons OR 1.61 × 10³ gallons.
Step-by-step explanation:
The amount of water in the tank after 15 days is given by the series
910+(−710)+810+(−610)+⋯+310+(−110)+210
From the series, we can observe that, if water is added for a particular day then water will be drained the following day.
Also, for a day when water is to be added, the quantity to be added will be 100 gallon lesser than the quantity that was last added. Likewise, for a day when water is to be drained, the quantity to be drained will be 100 gallons lesser than the quantity that was last drained.
Hence, we can complete the series thus:
910+(−710)+810+(−610)+710(-510)+610(-410)+510(-310)+410(-210)+310+(−110)+210
To evaluate this, we get
910-710+810-610+710-510+610-410+510-310+410-210+310-110+210
= 1610.0 gallons
Hence, the quantity of water in the tank after 15 days is 1610 gallons OR 1.61 × 10³ gallons.

What is 7% tax of 20$ purchase
Answer:
$1.4
Step-by-step explanation:
[tex]7 \% \: of \: 20[/tex]
% means (/100)
[tex] \frac{7}{100} \times 20 \\ \\ = \frac{140}{100} = \frac{14}{10} \\ = 1.4[/tex]
which equation represents a line that passes through 4 6) and is parallel to the line whose equation is 3x - 4y= 6
TIMED TEST WILL GIVE BRAINLIEST
Parallel means their slopes should equal to each other.
Thus we need to find the slope of the given line ,
Let's do it.....
[tex]3x - 4y = 6[/tex]
Subtract sides -3x
[tex] - 3x + 3x - 4y = - 3x + 6[/tex]
[tex] - 4y = - 3x + 6[/tex]
Divided sides by -4
[tex] \frac{ - 4}{ - 4}y = \frac{ - 3}{ - 4}x + \frac{6}{ - 4} \\ [/tex]
[tex]y = \frac{3}{4}x - \frac{3}{2} \\ [/tex]
This is the slope-intercept of the line.
We know that the coefficient of the x in slope-intercept form , is the slope of the line.
Thus the slope of the equation which we want is :
[tex]slope = \frac{3}{4} \\ [/tex]
_________________________________
We have following equation to find the point-slope form of the linear functions.
[tex]y - y(given \: point) = slope \times (x - x(g \: p) \: ) \\ [/tex]
Now just need to put the slope and the given point in the above equation.
[tex]y - 6 = \frac{3}{4} \times (x - 4) \\ [/tex]
Multiply sides by 4
[tex]4(y - 6) = 3(x - 4)[/tex]
[tex]4y - 24 = 3x - 12[/tex]
Plus sides 24
[tex]4y - 24 + 24 = 3x - 12 + 24[/tex]
[tex]4y = 3x + 12[/tex]
Subtract sides -3x
[tex]4y - 3x = 3x - 3x + 12[/tex]
[tex]4y - 3x = 12[/tex]
And we're done....♥️♥️♥️♥️♥️
0,4 Find the roots of the following quadratic equations
using the quadratic formula
1) 6a²x² - 7abx - 3b²=0, a is not equal to zero
pls answer
Answer:
b = b2-4ac
= (-7ab)^2 -4 (6a^2)(-3b^2)
= 49a^2b^2 + 72a^2b^2
= 121a^2b^2
Now, x = (7ab +- root 121a^2b^2)÷2(6a²)
= (7ab +- 11ab ) ÷ 12a²
= ( 20ab)/12a² or 4ab/12a²
= 5/3ab or - 1/3ab .
So, these are its roots .

If a flagpole is 30 feet tall and Mai-Lin is
standing a distance of 15 feet from the flagpole, what
is the distance from her feet to the top of the flagpole?
Add the information given.
She is 15 feet away:
15 + ? = ?
The pole is 30 feet, and it is asking distance to the top.
15 + 30 = ?
15 + 30 = 45
Answer:
about 33.5 ft
Step-by-step explanation:
The distance from Mai-Lin’s feet to the top of the
flagpole is about 33.5 ft.

HELP ASAPP... Find the volume of a cylinder with a radius of 5 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest tenth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
1177.5 in³
Step-by-step explanation:
To find the volume of a cylinder, you need to do this:
V= π r² h
Substitute in 3.14, 5, and 15
V= 3.14 x 5² x 15
Multiply 5 by itself
V= 3.14 x 25 x 15
Multiply 3.14 and 25
V= 78.5 x 15
Multiply 78.5 x 15 to get your answer:
V= 1177.5 in³

What is the equation of the line that is perpendicular to the line y = 2x+5 and
passes through the point (-4, 2)?
O A. y = -1/2x+2
B. y = 2x + 6
O C. y = 2x-6
O D. y=-1/2x
Answer:
y= -1/2x
Step-by-step explanation:
perpendicular is the opposite slope so -1/2 is the opposite slope of 2y=mx+b to solve for b I was taught to plug in what you have so2= -1/2(-4)+b2=2+bsubtract 2 on both sides to get b=0129 times 6+1 pronto fast

of male teachers is 12, find the number of female teachers.
d)
7
Answer:
there is 16 female teachers because 4 * 4 is 14
male is eqaul to 12
so therefore female is eqaul to 3/4*12=9
3y-4x=9
standard to slope
3y - 4x = 9
3y = 4x + 9
y = 4/3x + 3

Marshall knows that he burns 235 calories by walking for 30 minutes. This week, Marshall walked for 360 minutes. How many calories did Marshall burn by walking this week?
Answer:
2820 calories
Step-by-step explanation:
Since 30 can fit into 360, you can divide it.
360/30=12
12 is what you will multiply to the number of calories in 30 minutes.
235*12=2820
