After 2 months, the gym memberships at Gym A and Gym B will cost the same amount, based on the membership cost equations of each gym.
Explanation:We need to determine after how many months the total costs of gym memberships at Gym A and Gym B will be the same. The cost of a gym membership at Gym A is described by the equation C = 12m + 36, where C represents the total cost and m represents the number of months. For Gym B, the cost is given by the equation C = 20m + 20.
To find the number of months where the costs are equal, we set the two equations equal to each other:
12m + 36 = 20m + 20
Subtracting 12m from both sides gives us:
36 = 8m + 20
Subtracting 20 from both sides gives us:
16 = 8m
Dividing both sides by 8 gives us:
m = 2
Therefore, after 2 months, the total costs for gym memberships at both Gym A and Gym B will be the same.

Claudine traded U.S. dollars for Mexican pesos at an exchange rate of 1 U.S. dollar = 12.6577 Mexican pesos. She gave the exchanger a total of 2300 U.S. dollars and was charged a flat fee of 55 U.S. dollars. Approximately how many Mexican pesos does Claudine have?
Answer:
Step-by-step explanation:
You have to start by taking away $55 from the 2300. The 55 does not get exchanged.
2300 - 55 = 2245
1 US dollar = 12.6577 pesos
2245 US dollars = x Cross multiply
x = 12.6577 * 2245
x = 28416.54 pesos. (rounded to 2 places)
Answer:
$28,416.54 Mexican pesos
Step-by-step explanation:
That $2,300 will be divided into two parts: 1) $55 fee and 2) equivalent amount in Mexican pesos:
The amount exchanged into pesos is $2,300 - $55, or $2,245.
Converting this into pesos:
$2,245 12.6577 Mex pesos
------------ * ------------------------------- = $28,416.54 Mexican pesos

Janelle invested $13000 into two mutual funds. Fund A earned 6% profit during the first year, well fund B suffered a 3.5% loss. If she received a total of 324$ profit, how much had she invested in each mutual fund?
Answer:
amount invested in mutual fund B; $4,800
amount invested in mutual fund A; $8,200
Step-by-step explanation:
Let the amount invested in mutual fund B be x. Then the amount invested in fund A would be;
(13000-x)
The loss emanating from fund B would be;
3.5% of x
=(3.5/100)*x
=0.035x
The profit resulting from investment in fund A would be;
6% of (13000-x)
= (6/100)*(13000-x)
=0.06(13000-x)
=780-0.06x
The total profit earned from funds A and B in terms of x will be;
780 - 0.06x + (-0.035x)
=780 - 0.095x
The total profit earned was 324, thus;
780 - 0.095x = 324
solving for x;
780 - 324 = 0.095x
456 = 0.095x
x = 4800
Then the amount invested in fund A would be;
13000 - 4800 = 8200
(X-2) is a factor of x^4+2x^3-7x^2-8x+12. The other factors are ____, ____, and _____
We have
[tex]\dfrac{x^4+2x^3-7x^2-8x+12}{x-2}=x^3+4x^2+x-6[/tex]
The rational root theorem suggests that other possible roots may be -6, 6, -3, 3, -2, 2, -1, and 1. It turns out that [tex]x=-2[/tex] is a root, since [tex](-2)^3+4(-2)^2+(-2)-6=0[/tex], so [tex]x+2[/tex] is also a factor and we have
[tex]\dfrac{x^4+2x^3-7x^2-8x+12}{(x-2)(x+2)}=x^2+2x-3[/tex]
Finally, we can factorize the remaining quotient easily:

If the scale on a map is 1 cm for every 117 km and Washington, D.C., and Baghdad, Iraq, are 85.26 cm apart on the map, then approximately how far apart are they really?
If 1 cm represents 117 Km.
Then, 85.26 cm represents 117×85.26=9975.42 Km
therefore, the given places are 9975.42 Km apart from eachother.
The distance between Washington, D.C., and Baghdad, Iraq, are approximately 9,764.82 km apart in real life.
What is the scale factor?The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.
We are given that;
11cm=117km
Distance of baghdad and iraq= 85.26cm
Now,
If the scale on a map is 1 cm for every 117 km and Washington, D.C., and Baghdad, Iraq, are 85.26 cm apart on the map, then we can use the scale to find the actual distance between the two cities.
We can set up a proportion to solve for the actual distance:
1 cm / 117 km = 85.26 cm / x
To solve for x, we can cross-multiply:
1 * x = 117 * 85.26
x = 9,764.82 km
Therefore, by the scale factor the answer will be 9,764.82 km.

It is hard to calculate the volume of a mountain but several estimates put the volume of Mount Everest at around 2,413 cubic kilometers. The Dallas Cowboys Stadium (currently the largest football stadium in the U.S.) has a volume of 140 million cubic feet. How many Cowboy stadiums could fit inside of Mount Everest?
Estimate an answer to this question and explain your estimation process. Be sure to state what facts or ideas you used to help.
Answer:
About 609,000 Cowboy stadiums could fit inside of Mount Everest
Step-by-step explanation:
we have
The estimate volume of Mount Everest is at around [tex]2,413\ km^{3}[/tex]
The Dallas Cowboys Stadium has a volume of [tex]140,000,000\ ft^{3}[/tex]
step 1
Convert ft³ to km³
we know that
1 km=3,280.84 ft
so
[tex]140,000,000\ ft^{3}=140,000,000*(1/3,280.84)^{3}=0.003964\ km^{3}[/tex]
step 2
To find how many Cowboy stadiums could fit inside of Mount Everest, divide the volume of Mount Everest by the volume of the Dallas Cowboys Stadium
[tex]2,413/0.003964=608,729[/tex]
Round to the nearest Thousands
[tex]608,729=609,000[/tex]
The volume of Mount Everest is about 609,000 times greater than the volume of the Dallas Cowboys Stadium
To estimate how many Dallas Cowboys stadiums could fit inside Mount Everest, we converted the volume of the stadium to cubic kilometers and then divided Mount Everest's volume by this number, resulting in approximately 608,845 stadiums.
Explanation:Calculating the Volume of Mount Everest Compared to the Dallas Cowboys Stadium
To estimate how many Dallas Cowboys stadiums could fit inside of Mount Everest, we need to convert the volume of both structures to the same units and then perform a division.
We have the volume of Mount Everest as approximately 2,413 cubic kilometers. To convert the volume of the Dallas Cowboys Stadium from cubic feet to cubic kilometers, we use the conversion factor of 1 cubic kilometer equals 35.3147 million cubic feet:
Cowboys Stadium volume in cubic kilometers = 140 million cubic feet × (1 cubic kilometer / 35.3147 million cubic feet) = 3.9642 × 10-3 cubic kilometers.
Now, we can find how many Cowboys stadiums fit into Mount Everest:
Mount Everest volume / Cowboys Stadium volume = 2,413 cubic kilometers / 3.9642 × 10-3 cubic kilometers ≈ 608,845.
Therefore, approximately 608,845 Dallas Cowboys stadiums could fit inside of Mount Everest's volume.
Evaluate the expression. Express the result in scientific notation.
(9.08 × 106) – (2.25 × 105)
To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵), align the exponents and then subtract the base numbers, resulting in (8.855 × 10⁶) expressed in scientific notation.
To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵) and express the result in scientific notation, we will align the exponents and then subtract the base numbers. Since the exponents are not the same, we need to adjust the smaller exponent to match the larger one.
First, we rewrite (2.25 × 10⁵) with a base of 10⁶, which becomes (0.225 × 10⁶). Now we can subtract:
(9.08 × 10⁶) - (0.225 × 10⁶) = (9.08 - 0.225) × 10⁶
Performing the subtraction, we get:
(8.855 × 10⁶)
A rectangle container that has a length of 25cm,a width of 37cm, and a height of 21cm a is filled with water to a depth of 18 cm. When an additional 7 liters of water are poured into the container, some water overflows.How many liters water overflows the container?use words,pictures,and numbers to explain your answer.(Remember:_1cm3=1 mL.)
Answer:
4.225 L
Step-by-step explanation:
The box has a height of 21 cm. After the box is filled to 18 cm, there's 3 cm left of space. The volume of this space is:
V = lwh
V = (25 cm) (37 cm) (3 cm)
V = 2775 cm³
1 cm³ is the same as 1 mL, so the volume of the space is 2775 mL.
1 L is 1000 mL, so this volume is 2.775 L.
7 L of water is then poured in. The box can hold 2.775 L. The rest overflows. The overflow volume is:
7 L - 2.775 L = 4.225 L
Final answer:
The volume of water that overflows from the container after pouring an additional 7 liters is 4,225 mL or 4.225 liters.
Explanation:
The question involves calculating the volume of water that overflows from a rectangular container when additional water is poured in. The existing water depth, dimensions of the container, and the volume of the additional water are given. We know that 1 cm³ of water is equivalent to 1 mL, and there are 1000 mL in 1L.
The initial water volume in the container is the product of the length, width, and depth filled with water. Thus, the initial volume is:
25 cm (length) × 37 cm (width) × 18 cm (depth) = 16,650 cm³ (or mL)
When an additional 7 liters (which is 7,000 mL) of water is added to the container, the total volume of water becomes:
16,650 mL + 7,000 mL = 23,650 mL.The full capacity of the container is calculated by multiplying its length, width, and height:
25 cm × 37 cm × 21 cm = 19,425 cm³ (or mL).By subtracting the full capacity from the total volume after pouring:
23,650 mL - 19,425 mL = 4,225 mL (or 4.225 liters)We find that 4,225 mL (or 4.225 liters) of water overflows.

Find the Quotient: 6/ 27L 600ML
Answer:
400mL/3l
Is the correct answer
Step-by-step explanation:
To find the quotient of 6 liters by 27 liters and 600 milliliters, convert both to milliliters and divide. The quotient is approximately 0.21739.
To find the quotient of 6 liters (L) divided by 27 liters and 600 milliliters (mL), we first need to convert the amounts to the same unit. Since there are 1,000 milliliters in a liter, we can convert 27 liters into milliliters:
27 L × 1,000 mL/L = 27,000 mL
Now we add the 600 mL:
27,000 mL + 600 mL = 27,600 mL
Rewrite the problem with both measurements in milliliters:
6,000 mL / 27,600 mL
We now divide 6,000 by 27,600:
6,000 mL / 27,600 mL = 0.21739 (rounded to five decimal places)
So, the quotient is approximately 0.21739.

Final answer:
To simplify the expression, distribute the -1.01 across the parentheses, combine like terms, and the simplified result is 14.652c - 21.22b. Given values for a, b, and c are not needed.
Explanation:
To simplify the algebraic expression 9.4c - 1.01∙(22b - 5.2c) + b, we first distribute the -1.01 across the parentheses, and then combine like terms.
Step-by-Step Explanation:
Distribute -1.01 to each term inside the parentheses: -1.01 * 22b = -22.22b, and -1.01 * (-5.2c) = 5.252c.
Combine the distributed terms with the original expression: 9.4c - 22.22b + 5.252c + b.
Combine like terms: (9.4c + 5.252c) + (b - 22.22b).
Adding c terms together gives 14.652c, and combining b terms gives -21.22b(because 1b - 22.22b equals -21.22b)
The simplified expression is now 14.652c - 21.22b.
Note: The given values a = 1, b = 0.0211, and c = -0.0211 are not relevant to the simplification process.

f(x) = 10(x^2 + 8x + 22) = 0
Complete the square of x^2 + 8x + 22 only, for now.
Identify the coefficient of the x term. It is 8. Take half of that (it is 4) and square your result: 16
Now add 16 to x^2 + 8x and then subtract 16 from that sum:
x^2 + 8x + 16 - 16 + 22 = 0, or
x^2 + 8x + 16 + 6 = 0
Rewrite x^2 + 8x + 16 as (x + 4)^2
and then the whole expression x^2 + 8x + 16 - 16 + 22 as (x + 4)^2 = -6
Finally, rewrite this as
f(x) = 10 [ (x + 4)^2 = -6 ] which is the desired form of the original equation.
Answer:
The answer is
[tex](x+4)^2=-6[/tex]
Step-by-step explanation:
Follow the steps below.
1) Take common factor 10
[tex]10(x^2 + 8x + 22) = 0[/tex]
2) For an equation of the form [tex]ax ^ 2 + bx + c[/tex]
Calculate [tex](\frac{b}{2})^2[/tex]
In this case the equation is [tex]x^2 + 8x + 22= 0[/tex]
[tex]a=1\\b=8\\c =22\\\\(\frac{b}{2})^2 = (\frac{8}{2})^2 = 16[/tex]
3) Add 16 on both sides of equality
[tex]10(x^2 + 8x + 16) +220= 16*10[/tex]
4) Factor the expression into parentheses and simplify
[tex]10(x+4)^2 +220= 16*10[/tex]
[tex]10(x+4)^2= 16*10-220[/tex]
[tex]10(x+4)^2 =-60[/tex]
[tex](x+4)^2 =-6[/tex]
