A fish tank holds 832 gallons but is leaking at a rate of 5 gallons per week. A second fish tank hose 1040 gallons but is leaking any rate of 9 gallons per week after how many weeks with the amount of water in the two fish tanks me the same
Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52

The inverse of the function f(x) = {x+
+ 10 is shown
h(x) = 2x-0
What is the missing value?
A. 1
B.5
C.10
D.20
Answer:
D
Step-by-step explanation:
f(x) = x + 10
Replace f(x) with y.
y = x + 10
Now, remember that in an inverse function you flip the x and y, so
x = y + 10
Solve for y
y = x - 10
because its 2x... we must multiply by 2.
2y = 2x - 20
Original equation:
h(x) = 2x - 0
h(x) is 2y..
D.
Answer:
The missing value is 20

Eric has $4,610 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much will he have in 2 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
$ ___
Answer:
$ 4,986.18
Step-by-step explanation:
A = $ 4,986.18
A = P + I where
P (principal) = $ 4,610.00
I (interest) = $ 376.18
The rubber track for a toy digger goes around four circular wheels of diameter 8 cm, as shown. (b) Calculate the length of the rubber track that goes around the four wheels. Give your answer correct to one decimal place.
Answer:
73.1 cm
Step-by-step explanation:
In the drawing, the rubber track is in black and the wheels are in light gray.
As we can see in the figure, the rubber track will have a length of two halfs of a circunference of radius 8 cm plus six diameters of 8 cm. So the total length is:
Length of rubber track = pi * 8 + 6 * 8 = 25.13 + 48 = 73.133 cm
Rounding to one decimal place, we have that the length is 73.1 cm
This question is incomplete because it lacks the diagram of the 4 circular wheels.
Find attached to this answer the appropriate diagram
Answer:
100.5cm
Step-by-step explanation:
The formula to be used in this calculation is the circumference of a circle.
The circumference of a circle can be defined as the actual length of a circle when it is stretch out(opened up) or the distance around a circle.
The formula for the circumference of a circle is given as 2πr where r = radius of the circle
Or πD where D = Diameter of the circle
In the question, we are given the diameter of the circle = 8cm
So we use the Formula
= πD
The length of the rubber track around one wheel is
= π × 8cm = 25.132741229cm
From the attached diagram, we can see we have 4 wheels.
The length of the rubber track that goes around the four wheels is calculated as
4 × 25.132741229cm = 100.53096491cm.
Approximately to one decimal place = 100.5cm
Therefore, the length of the rubber track that goes around the four wheels to one decimal place is 100.5cm
What is the value of C in the equation 4c-6=22

Paloma added a garden to her painting. She has 12 rows of flowers. Each row has 13 plants in it. Each plant has 15 flowers on it. How many flowers are in Palomas garden?
Answer: 2340 flowers
Step-by-step explanation:
From the question, Paloma added a garden to her painting. She has 12 rows of flowers and each row has 13 plants in it while each plant has 15 flowers on it. To calculate the number of flowers in Palomas garden, we multiply the number of rows by the total number of plants and the number of flowers in each plant. This will be:

Find the surface area of the suitcase
Answer:
1,344 square inches
Step-by-step explanation:
First, determine the faces that you have to find the areas of! In this situation, you need to find the areas of two trapezoids and four rectangles.
Finding the area of a trapezoid is pretty straightforward! Simply find the average of the two bases and multiply that by the height. ((5+15)/2)*12 should equal the area of one trapezoid. Because they're both the same trapezoid, you can multiply this area by two in order to get the area of both. This will get you 240.
Now, find the area of each of the rectangles by multiplying their individual bases and heights together. You'll find them to be 312, 360, 120, and 312.
Lastly, add all the areas together to get the total surface area.

There were seven friends playing a video game online when two more players joined the game. If each player had seven lives, how many lives did they have total?
Answer:
14 lives in total
Step-by-step explanation:
7*7=14
Answer:
63 lives
Step-by-step explanation:
You had 7 players, and two more joined. Add these together for the total amount of players.

9 × 7 = 63
There are 63 total lives.
If triangle ABC defined by the coordinates A(1,1), B(9,1), C(1,9) is dilated by a scale factor of 1/2
Answer:
The transformed points of the triangle ABC are [tex]A' (x,y) = \left( \frac{1}{2}, \frac{1}{2}\right)[/tex], [tex]B'(x,y) = \left(\frac{9}{2}, \frac{1}{2} \right)[/tex], [tex]C'(x,y) = \left(\frac{1}{2}, \frac{9}{2}\right)[/tex]
Step-by-step explanation:
The new points after applying the scale factor are, respectively:
[tex]A' (x,y) = \frac{1}{2}\cdot (1,1)[/tex]
[tex]A' (x,y) = \left( \frac{1}{2}, \frac{1}{2}\right)[/tex]
[tex]B' (x,y) = \frac{1}{2}\cdot (9,1)[/tex]

Betty has a checking account and a non-interest bearing savings account. The function C(x), shown below, represents her checking
account balance, where x is the number of months. The function S(x), shown below, represents her saving account balance.
C(x) = -2401 - 140 + 1,400
S(s) = 4503 + 100
Which function represents Betty's total account balance. T(x)?
Answer:
T(x) or total account balance = C(x) + S(x)
Step-by-step explanation:
where = C(x) = -2401 - 140 + 1,400
and
S(x) = 4503 + 100
This implies that:
C(x) = 3,661
S(x) = 4,603
Therefore, T(x) 3,661 + 4,603 = 8,264
T(x) is the total account balance or the addition of the balances of checking and saving accounts.
C(x) is the checking account balance.
S(x) is the saving account balance.

[tex] {x}^{3} = 74.088 \\ x = \sqrt[3]{74.088} \\ x = 4.2[/tex]
Answer:
4.2 cm
Step-by-step explanation:
The side of a cube cubed is equal to the volume.
a³ = V
The volume is already given, solve for the side.
a³ = 74.088
a = ∛74.088
a = 4.2
The side x is 4.2 centimeters.

The value of g is 12.8, the solution of the equation.
Here, we have,
The equation you provided is:
g/4 = 3.2
To solve for the value of g, we can multiply both sides of the equation by 4 to isolate g:
4 * (g/4) = 4 * 3.2
The 4 on the left side cancels out with the 4 in the denominator, leaving us with:
g = 4 * 3.2
Multiplying 4 and 3.2 gives us:
g = 12.8
Therefore, the value of g is 12.8.

Answer:
a) [tex]2.036x^-\frac{1}{3}[/tex]
b) [tex]\frac{x^2}{\sqrt{x+1} }[/tex]
Step-by-step explanation:
For a cube, all the sides are equal. Let the length of each side be L
a) The volume of a cube (V) = L³
For the first cube:
V = 270x in³
270x = L³
L = ∛(270x) = [tex]6.463x^\frac{1}{3}[/tex]
For the second cube:
V = 32x² in³
32x² = L³
L = ∛(32x²) = [tex]3.175x^\frac{2}{3}[/tex]
Ratio of length = [tex]\frac{6.463x^\frac{1}{3} }{3.175x^\frac{2}{3} }=2.036x^-\frac{1}{3}[/tex]
b) The surface area of a cube (s) = 6L²
For the first cube:
s = 6x⁴ ft²
6x⁴ = L²
L = √6x⁴= 2.45x²
For the second cube:
s = 6(x + 1) ft²
6(x + 1) = L²
L = √6(x + 1)= 2.45√(x + 1)
Ratio of the length = [tex]\frac{2.45x^2}{2.45\sqrt{ (x + 1)}} =\frac{x^2}{\sqrt{x+1} }[/tex]

Answer:
The answer on the top is the best line for a line of best fit because...
Step-by-step explanation:
there is a noticeable correlation in the first graph- a positive one. The line of best fit should have about the same amount of line plots on the top than on the bottom. Also, there can be a few line plots that is touching the line of best fit as well. Those line plots will be about the middle of the data and provide a good guideline to make your line of best fit the most accurate. The second graph is pretty scattered and doesn't have a clear correlation therefore having no correlation. Hope this helps!!
