Answer: It can not be a mixed number because if you divide -27 by 50 you get -0.54, so then if you turn -0.54 in fraction form it would be -27/50, so the fraction would stay the way it is. -27/50 is not an improper fraction. To be improper, the numerator must be greater than the denominator!

Thank you!
Answer:
[tex]=\frac{3x^{5}(y-z)}{2(y+z)}[/tex]
Step-by-step explanation:
[tex]\frac{15x^3 (y-z)^2}{10x^{-2}(y^2-z^2)}[/tex] We need to solve this equation.
We know (x^2-y^2) = (x-y) (x+y)
Using the above formula, and taking 5 common:
[tex]=\frac{3x^3 (y-z)^2}{2x^{-2}(y^2-z^2)}\\=\frac{3x^{3+2} (y-z)^2}{2(y^2-z^2)}\\=\frac{3x^{5} (y-z)(y-z)}{2(y-z)(y+z)}\\=\frac{3x^{5}(y-z)}{2(y+z)}[/tex]

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.
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

If you horizontally stretch the quadratic parent function, f(x)= x^2, by a factor of 4, what is the equation of the new function
Answer:
[tex]f(x) = \frac{1}{16}x^2[/tex]
Step-by-step explanation:
If the graph of the function [tex]y=f(hx)[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <h <1[/tex] the graph is stretched horizontally by a factor [tex]\frac{1}{h}[/tex]
If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]
In this problem we have the parent function [tex]y=x^2[/tex] And we know that it stretches horizontally by a factor of 4
Therefore
[tex]0 <h <1[/tex] and [tex]h=\frac{1}{4}[/tex]
The transformation is:
[tex]y=f(\frac{1}{4}x)[/tex]
And the function is:
[tex]f(x) = (\frac{1}{4}x)^2[/tex]
A company did a quality check on all the packs of roasted almonds it manufactured. Each pack of roasted almonds is targeted to weigh 21.25 oz. A pack must weigh within 0.24 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured roasted almonds?
x < 21.01 or x > 21.49 because |x − 0.24| + 21.25 > 0
x < 21.25 or x > 21.49 because |x − 21.25| > 0.24
x < 21.01 or x > 21.49 because |x − 21.25| > 0.24
x < 21.25 or x > 21.49 because |x − 0.24| + 21.25 > 0
Answer:
x < 21.01 or x > 21.49 because |x - 21.25| > 0.24
Step-by-step explanation:
We know that each pack of almonds is targeted to weigh 21.25 oz.and a pack must weigh within 0.24 oz of the target weight to be accepted.
Assuming x to be the weight of a given pack of almonds, we can write it as:
[tex]|x-21.25| > 0.24[/tex]
Now finding the range of rejected masses (x) of the almonds.
[tex]|x-a| >b[/tex]
[tex]-b<(x-a)< b[/tex]
[tex]|x-21.25| >0.24[/tex]
[tex]-0.24>(x-21.25)>0.24[/tex]
[tex]-0.24>x-21.25[/tex] or [tex]x-21.25>0.24[/tex]
[tex]x<21.01[/tex] or [tex]x>21.49[/tex]
Therefore, the correct answer option is x < 21.01 or x > 21.49 because |x - 21.25| > 0.24.

Please help me with this question! I will give title of Brainliest if correct.
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.

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

Adrian’s recipe for raisins muffins calls for 1 3/4 cups of raisins for one batch of muffins. Adrian wants to make 2 1/2 batches of muffins for a bake sale. How many cups of raisins will Adrian use?
(HAPPY EID TO ALL!!!)
Adrian will need 4 3/8 cups of raisins to bake 2 1/2 batches.
Convert the mixed fractions into improper fractions:
1 3/4 = 7/4
2 1/2 = 5/2
Multiplying fractions:
1) Multiply numerators
2) Multiply denominators
3) Simplify answer
7/4 * 5/2 = 7*5 / 4*2 = 35/8
35/8 can be simplified into a mixed fraction 4 3/8
Adrian needs to use 4 3/8 cups of raisins.
Answer:
4 3/8
Step-by-step explanation:
Step 1: Convert the numbers into improper fractions. To do this, multiply the denominator value by the whole number and then add the numerator to that product. 1 3/4 becomes 7/4 and 2 1/2 becomes 5/2.
Step 2: Multiply the fractions straight across. Multiply the numerators together and the denominators together. 7 * 5 is 35. 4 * 2 is 8. The improper fraction is 35/8.
Step 3: Convert the improper fraction to a mixed number. Do this by dividing the numerator by the denominator. 35/8 is 4 with a remainder of 3/8. 4 3/8 is the number of cups he will use to make his batches of muffins.
Write an algebraic expression in standard form for the shaded area of the following shape
Answer:
x² + 7x + 12
Step-by-step explanation:
The area of a rectangle = length × width
here length = x + 4 and width = x + 3, hence
A = (x + 4)(x + 3)
Each term in the second parenthesis is multiplied by each term in the first parenthesis.
A = x(x + 3) + 4(x + 3) ← distribute each parenthesis
A = x² + 3x + 4x + 12 ← collect like terms
A = x² + 7x + 12 ← in standard form

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]

10x2 + 80x + 220 = 0
Select the best answer from the choices provided
Answer:
f(x) = 10 [ (x + 4)^2 = -6 ]
Step-by-step explanation:
Please use " ^ " to indicate exponentation. Thanks.
Also, please share the possible answer choices. "Select the best answer from the choices provided."
Start with f(x) = 10x^2 + 80x + 220 = 0
Factor out the 10 to simplify this "completing the square."
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]

Five years after jari's age now doubles, he will be 27. How old is jari now
Answer:
8 or 8.5
Step-by-step explanation:
27 divided by 2 = 13.5
13.5 take away 5 = 8.5
The age of Jari now if the age after 5 years doubles is 11.
Given that:
Five years after jari's age now doubles, he will be 27.
Let x be the age of Jari now.
An equation can be formed with the given information.
When the age doubles, the age is 2x.
Five years after this age can be written as 2x + 5.
Now, it is given that this age is 27.
So,
2x + 5 = 27
Subtract both sides by 5.
2x = 27 - 5
2x = 22
Divide both sides by 2.
x = 22/2 = 11
Hence Jari is now 11 years old.

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.
