Answer:
I think that there might be some complex differential equation
stuff going on here if this were in the real world, but for the sake of this problem... may I suggest that the tank is filling up at a rate of
1/8 of a tank per hour...
it is evaporating at a rate of 1/12 tank per hour
you can subtract the rates
1/8 - 1/12 = 12/96- 8/96 = 3/96 = 1/32 tank/hr
so to fill the tank it should take 32 hours...
I think the logic and math work... lets see if someone else will verify this analysis?
Step-by-step explanation:
x + y = −3
y = 2x + 2
Answer:
Step-by-step explanation:
x + y = −3
y = 2x + 2
Substitute the y value of the second equation into the top equation
x + 2x + 2 = - 3
3x + 2 = - 3
3x = -3 -2
3x = - 5
x = -5/3
x + y = - 3
-5/3 + y = - 3
y = -3 + 5/3
y = -1 1/3
BRAINLIEST ANSWER TO WHOEVER ANSWERS FIRST... What is the volume of the sphere in terms of *pi ? in
Formula for the volume of a sphere: V = 4/3 x pi x r^3
V = 4/3 x pi x 6^3
V = 4/3 x pi x 216
V = 288 pi in^3
Hope this helps!
Answer:
288 pi in ^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3 where r is the radius
V = 4/3 pi *( 6)^3
V = 4/3 pi (216)
V = 288 pi in ^3

Answer: sqrt(x+1)+4
This is the same as writing [tex]\sqrt{x+1}+4[/tex]
The +4 is not under the square root
==========================================================
Explanation:
g(x) is the same as y, since they're both outputs of a function
So we have the starting equation y = (x-4)^2 - 1
Swap x and y and solve for y to get the inverse.
y = (x-4)^2 - 1
x = (y-4)^2 - 1
x+1 = (y-4)^2
(y-4)^2 = x+1
y-4 = sqrt(x+1) ... see note below
y = sqrt(x+1)+4
Note: Recall that [tex]x \ge 4[/tex] and we swapped x and y. This ultimately means [tex]y \ge 4[/tex] and this only occurs if we picked the positive version of the square root (ignoring the negative version).
What is the area for the circle?
Answer:
108 squared centimeters
Step-by-step explanation:
Let's exchange π for 3:
area = πr^2
= 3r^2
Now, as you can see, the radius of this circle is 6. Let's plug in the value of r:
area = 3r^2
= 3 · 6^2
Simplify 6^2:
area = 3 · 6^2
= 3 · 36
Multiply 3 by 36:
area = 3 · 36
area = 108
108 squared centimeters

Answer:
27.932 in
Step-by-step explanation:
The initial angle (or height) is not shown, so we have assumed it is 30°. The equation for the height of the valve cap can be written as a function of angle:
y = 15.375 +14.5·sin(x +30) . . . . . . where x is in degrees
The angle measured from the +x axis is already 30° when the rotation angle is zero. Evaluating the above equation with x = 390° gives an angle of 420°, or 60° beyond one full rotation.
y = 15.375 +14.5·sin(60°) ≈ 27.932 . . . . inches above the ground.
The valve cap is 27.932 in. above the ground.

Step-by-step explanation:
The value of x is 3 if the volume of the triangular prism is 54 cubic units.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that volume of the triangular prism is 54 cubic units.
We have to find the value of x
The volume of the prism with triangular base is 54 unit³.
The base is a triangle with,
base = 4 units
height = x units
height of the prism = 3x
V= 6x²
54= 6x²
Divide both sides by 6
x² = 9
x=3
Hence, the value of x is 3 if the volume of the triangular prism is 54 cubic units.

Many track hurdlers believe that they have a better chance of winning if they start in the inside lane that is closest to the field. For the data below, the lane closest to the field is Lane 1, the next lane is Lane 2, and so on until the outermost lane, Lane 6. The data lists the number of wins for track hurdlers in the different starting positions. Find the critical value to test the claim that the probabilities of winning are the same in the different positions. Use 0.05. The results are based on 240 wins.
Answer:
χ² = 6.75
χ² Critical = 11.07
Step-by-step explanation:
Given the data :
Expected winnings ;
1/n * total number of wins
Total number of wins = 240
n = number of starting positions = 6
Expected winnings = 1/6 * 240 = 40
Using χ² test :
χ² = Σ(O - E)² / E
O = Observed ; E = Expected
χ² = (32 - 40)^2 / 40 + (33 - 40)^2 / 40 + (45 - 40)^2 / 40 + (44 - 40)^2 / 40 + (50 - 40)^2 / 40 + (36 - 40)^2 / 40
= 6.75
χ² Critical at α = 0.05 ; df = n - 1 ; df = 5
χ² Critical = 11.07
Since χ² < χ² Critical ; WE fail to reject H0.
A rectangle has side lengths 2x + 3 and 5x - 2.
Write an expression without brackets for the area of the rectangle
Answer:
10x² + 11x - 6
Step-by-step explanation:
The area (A) is the product of the sides, that is
A = (2x + 3)(5x - 2) ← expand using FOIL
= 10x² - 4x + 15x - 6 ← collect like terms
= 10x² + 11x - 6

Answer:
B.
Step-by-step explanation:
Table B has x values that go to multiple y values. A function has inputs that only go to one output.
Please apply the properties of rational exponents to simplify expressions with radical or rational exponents. Explain the steps so that I understand because this is for my notes. Thank you for your time, the properties and problems to apply them to will be below.
Step-by-step explanation:
Product property
If the bases are the same, you don't multiple them. However, if they are the same, you do multiple for example : (2³ * 2¹ = 2⁴.when the bases are the same) (2³ * 3¹ =6⁴. When the bases are not the sameWe add the index.Quotient property
Same here, if the bases are the same, they stay the way they wereWe subtract the indexPower property
Here we multiple the index because of the bracket for example : (9²)²= 9⁴Negetive exponent property
When ever the index has a negative sign its convected to a fraction, for instance : 9¯² = 1 /9²Note, when it turns to a fraction th index becomes positiveAnswer problem below
Answer:
A = 2, B = 1, C = 28Step-by-step explanation:
Find the slope of the line AB.
The slope:
m = (11 - 9)/(11 - 7) = 2/4 = 1/2Since the altitude is perpendicular to AB, it has a slope of -2.
The line with the slope of -2 and passes through point C(6, 16).
Use point-slope equation to find the line:
y - 16 = -2(x - 6)y - 16 = -2x + 12y + 2x = 16 + 122x + y = 28A = 2, B = 1, C = 28
Answer:
Solution given:
A(7,9)
B(11,11)
C(6,16)
Slope of AB=[tex]\frac{11-9}{11-7}=\frac{2}{4}=½[/tex]
since altitude is perpendicular to it .
so its slope becomes negative reciprocal to the slope of base
so
slope of altitude(m) =-2
now
equation of a line passing through C(6,16) perpendicular to its base is:
By using formula
[tex]y-y_{1}=m(x-x_{1})[/tex]
y-16=-2(x-6)
solve it
y-16=-2x+12
y+2x=12+16
