Final answer:

The rectangle's width is found to be 7.3 cm, and the length is approximately 10.47 cm, both measured to three significant figures. This was determined by setting up equations based on the given perimeter and the relationship between the rectangle's length and width.

Explanation:

To find the dimensions of the rectangle, we need to set up an equation based on the given perimeter and the relationship between length and width.

Let's denote the width of the rectangle as w centimeters. According to the problem, the length l is 3 1/6 cm longer than the width, so l = w + 3 1/6 cm. The perimeter P of a rectangle is given by the formula P = 2l + 2w. Substituting the given perimeter 15 1/3 cm and the expression for l into the formula, we get:

15 1/3 = 2(w + 3 1/6) + 2w

To solve, first convert the mixed numbers to improper fractions:

46/3 = 2((6w + 19)/6) + 2w

Multiply through by 6 to clear the fractions, resulting in:

92 = 4w + 19 + 6w

Combine like terms and solve for w:

92 = 10w + 19

73 = 10w

w = 7.3 cm

Now that we have the width, calculate the length:

l = w + 3 1/6

l = 7.3 + 3 1/6

l = 7.3 + 19/6

l = 7.3 + 3.1667

l = 10.4667 cm

So the width of the rectangle is 7.3 cm, and the length is approximately 10.47 cm, to three significant figures.

Answer:

$39.50

Step-by-step explanation:

Multiply 7.9 by 5 to get 39.5

Answer:

if 10 of them costs $7.90 then 50 would cost $39.50.

there are two different ways of doing this:

1. you could divide $7.90 by 10 which would get you $0.79 (the price of one frozen juice bar) then multiply $0.79 by 50 to get $39.50 (the price of 50 frozen juice bars)

or

2. you could just take $7.90 and multipy it by 5 (b/c 10 x 5 is 50)

Answer:

The solution set can be given as:

[tex]\{x|x\ \epsilon\ R,x\neq -3\}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=\frac{1}{2x+6}[/tex]

To find the domain of the function in set notation.

Solution:

For the function [tex]f(x)[/tex] to exist the denominator must be ≠ 0

We have the denominator [tex](2x+6)[/tex] which  cannot be = 0.

Thus, we can find the domain of the function using the above relation.

The function [tex]f(x)[/tex] will not exist when:

[tex]2x+6=0[/tex]

Solving for [tex]x[/tex]

Subtracting both sides by 6.

[tex]2x+6-6=0-6[/tex]

[tex]2x=-6[/tex]

Dividing both sides by 2.

[tex]\frac{2x}{2}=\frac{-6}{2}[/tex]

∴ [tex]x=-3[/tex]

Thus, the function will not exist at [tex]x=-3[/tex]. This means it has all real number solutions except -3.

The solution set can be given as:

To find the length of segment EF, first equate ED and DF as D is the midpoint, solve for x, and then calculate EF as 2 times either ED or DF.

To find the length of segment EF, we need to use the given information: since D is the midpoint of EF, ED is equal to DF. The expressions given for ED (4x + 6) and DF (7x - 9) can therefore be set equal to each other to solve for x:

4x + 6 = 7x - 9

After solving for x, we can find the lengths of ED and DF, which are equal. Finally, we get the total length of EF by adding ED plus DF (or simply 2 times one of them since they're equal).

Here's how you solve for x:
3x = 15
x = 5

Now, substitute x back into one of the original equations to find one of the segment lengths:
ED = 4(5) + 6 = 20 + 6 = 26

Therefore, EF, which is made up of two segments of length 26, is 26 + 26 = 52 units long.

To find the length of EF, use the fact that D is the midpoint of EF. Set ED and DF equal to each other, solve for x, and substitute the value of x back into either ED or DF to find the length of EF.

To find the length of EF, we can use the fact that D is the midpoint of EF. This means that ED is equal to DF.

Given that ED = 4x + 6 and DF = 7x - 9, we can set these two expressions equal to each other:

4x + 6 = 7x - 9

Simplifying the equation:

6 + 9 = 7x - 4x

15 = 3x

Dividing both sides by 3:

x = 5

Now, we can substitute this value of x back into either ED or DF to find the length of EF. Let's use ED:

EF = 4x + 6 = 4(5) + 6 = 20 + 6 = 26

Therefore, EF = 26.

The equivalent expression is 12j + 21 and 3(4j + 7)

Solution:

Given that we have to write 2 equivalent expression

Given expression is:

3(3j + 7 + j)

Combine the like terms. Combine 3j and j we get 4j

Thus the expression becomes,

3(4j + 7)

Now let us use distributive property

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

The distributive property is represented as:

a(b + c) = ab + ac

Apply distributive property in 3(4j + 7)

[tex]3(4j + 7) = 3 \times 4j + 3 \times 7\\\\3(4j + 7) = 12j + 21[/tex]

Thus one of the equivalent expression is 12j + 21

Second equivalent expression:

From first equivalent expression,

12j + 21

Factor out the greatest common factor

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 21 are: 1, 3, 7, 21  

Then the greatest common factor is 3

Thus factor out 3 from 12j + 21

[tex]12j + 21 = 3(4j + 7)[/tex]

Thus the another equivalent expression is 3(4j + 7)

Answer:

2.15

Step-by-step explanation:

The easiest way to convert a percentage to a decimal is to simply add a decimal on the number (If the number does not already have one), then move that decimal two places to the left.

We can do that like so:

1: Remove the percentage sign: 215% -> 215

2: Add a decimal at the end of the number: 215.

3: Move the decimal two places to the left: 2.15

So 215% converted to a decimal would be 2.15

Allow me to review before I start.  Inconsistent means there's no solution to the system of simultaneous equations, i.e. parallel lines.  Consistent means there's at least one solution.  Independent and dependent apply to consistent systems.  The former means exactly one solution (two lines in different directions which meet).  Dependent means an infinite number of solution; the two lines are really the same line.

1. We have two different slopes, lines in two different directions, so they'll meet in exactly one place.  That system is consistent and independent, the usual case.

2. We can write the first one y-3x= -2 and the second y-3x=+2.  These are parallel lines that are different, so no solution: inconsistent.

3.  The first equation is x+2y=4, same as the second. An infinite number of solutions.  Consistent and dependent.

By rewriting the 3 given systems, we will see that:

Let's analyze each system.

Let's look at the first one, we can rewrite it as:

y = 2x + 3

y = -x - 3

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

Now let's look at the second system, we can rewrite it as:

y = 3x - 2

y = 3x + 2

Here both lines have the same slope, so the lines never do intersect, meaning that the system is inconsistent and independent.

For the final system we have:

y = (-1/2)*x + 2

y = (-1/2)*x + 2

So, we have two equal lines, so this system is dependent.

Final answer:

Craig, Ester, and Lisa wrote correct expressions equivalent to 8x - 20. Ali's expression is incorrect due to improper distribution of the negative sign, resulting in an expression equivalent to 8x + 20, rather than 8x - 20.

The expressions provided by the students need to be equivalent to 8x - 20. We can factor out a common factor or distribute and combine like terms to check the equivalence of each expression:

For the incorrect expression (-4)(2x + 5), Ali likely distributed the negative incorrectly. Ali should have distributed the negative sign across the terms inside the parenthesis, producing -8x - 20, which is equivalent to 8x + 20, and not 8x - 20.

Step-by-step explanation:

Write as an algebraic equation.

Look at each part in the word question : 0.7 of what number is 4 1/2

"0.7 of what number" can be written as 0.7x

The word "is" means equals.

0.7x = 4 1/2     <= The equation, using 'x' to represent the number.

To find the number, isolate 'x'.

0.7x = [tex]4\frac{1}{2}[/tex]    Convert mixed fraction to improper fraction

0.7x = [tex]\frac{(4*2)+1}{2}[/tex]     Multiply the whole number by the denominator and add it to the numerator

0.7x = [tex]\frac{9}{2}[/tex]     Now isolate 'x'

0.7x/0.7 = [tex]\frac{9}{2}/0.7[/tex]     Divide both sides by 0.7

x = [tex]\frac{9}{2}/0.7[/tex]     Simplify right side

x = [tex]\frac{9}{2}/\frac{7}{10}[/tex]     Rewrite 0.7 as a fraction

x = [tex]\frac{9}{2}*\frac{10}{7}[/tex]     To divide, you multiply a flipped fraction

To find the total amount of water needed to water all the plants in the house, the amount of water for a part of the plants is used to set up a proportion. After cross-multiplying and calculating, it is determined that 10/3 liters or approximately 3.33 liters of water is required.

If 4/3 liters of water is enough for 2/5 of the plants, then the amount of water required for all the plants can be found by setting up a proportion. We use cross-multiplication to solve for the unknown amount of water needed to water all the plants.

First, we express the given information as a fraction:

(4/3) liters

(2/5) plants

Next, we solve for the total water required (let's call it x):

(4/3) / (2/5) = x / 1

We cross-multiply to solve for x:

4/3 * 1 = x * (2/5)

Multiplying both sides by the reciprocal of (2/5), which is (5/2), to isolate x, we get:

(4/3) * (5/2) = x

Now we calculate:

x = (4 * 5) / (3 * 2) = 20/6 = 10/3 liters

Therefore, 10/3 liters of water, or approximately 3.33 liters, is necessary to water all the plants in the house.

The answer to 3 significant figures is 19.7

The question seeks to find the size of angle YZX in a triangle but lacks the necessary information to provide an accurate answer. By using the sum of the angles in a triangle (180 degrees), we could find the angle YZX if we had the other two angle measurements.

Your question is a mathematical one, specifically within the study of geometry, but it seems to be missing information needed to provide a specific answer. Determining the size of Angle YZX would depend on other given angles or measurements within the triangle. For example, if we know the other two angles, we could calculate Angle YZX by subtracting the sum of the other two angles from 180 (as the total degrees in a triangle is 180). Furthermore, the number of significant figures doesn't affect the calculation of an angle, it only refers to how precise your final answer should be represented. In this case, the answer should be given to three significant figures. Let's say that the value of Angle YZX was calculated to be 123.456 degrees, then presenting this to three significant figures would result in 123 degrees.
