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:

The full capacity of the container is calculated by multiplying its length, width, and height:

By subtracting the full capacity from the total volume after pouring:

We find that 4,225 mL (or 4.225 liters) of water overflows.

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.

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.

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.

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

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:

[tex]x^2+2x-3=(x+3)(x-1)[/tex]

so the other factors are [tex]x+2[/tex], [tex]x+3[/tex], and [tex]x-1[/tex].

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]

[tex](x+4)^2 =-6[/tex]

Step-by-step explanation: so I did 1×3/12+1×4/12 (3+4)/12 =7/12

Answer:

D. 7/36 pounds

Step-by-step explanation:

Combine the two using like terms so 1/3 and 1/4 = 4/12 and 3/12 so 4+3=7 so 7/12.

Next you divide by 3. To do this, find a larger denominator with a number that can be divided by 3.

7/12 to 14/24 and 21/36. 21 can be divided by 3.

Divide 21/36 by 3 and get 7/36. This can not be simplified any further.

Therefore your answer is D. 7/36.

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]

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]

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.

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.

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

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.
