chose the pieces with no symmetry

I believe it would be 673.98

I hope this helps :)

673.983 rounded to the nearest hundredth is 673.98, as the third decimal digit (3) is less than 5.

To round the number 673.983 to the nearest hundredth, we need to look at the third decimal place, which is in the thousandths place. If this digit is 5 or greater, we round up. If it is less than 5, we keep the second decimal place as it is. In the case of 673.983, the third decimal digit is a 3, which is less than 5. Therefore, the number rounded to the nearest hundredth is 673.98.

Aurora used 4 gigabytes of data in September.

To determine how many gigabytes of data Aurora used in September, we need to subtract the fixed phone service charge from her total bill. The difference will represent the additional charges for the data usage. Let's say she used x gigabytes. The equation for her bill can be written as: 65 + 12x = 113. To solve for x, we can subtract 65 from both sides and then divide both sides by 12 to isolate x. Solving this equation, we find that x = 4. So, Aurora used 4 gigabytes of data in September.

We can write this line in y-intercept form, and then solve to convert it to standard form.

Y = mx + b

m = slope

b = y-intercept

Y = -1/4x - 2 is the slope-intercept form of the equation.

Now, we can convert this to standard form.

Add 2 to both sides.

y + 2 = -1/4x

Subtract y from both sides.

-1/4x - y = 2

Multiply all terms by -4.

x + 4y = -8 (This is your answer.)

Answer:

2.81 and 0.3 are two decimals that give a product of 8.43 which is close to 8.4

Step-by-step explanation:

let consider a decimal number 0.3

now consider another decimal number 2.81

now if we multiply these two numbers then we get 8.43 which is also a decimal number and it is close to 8.4.

Answer:

Hence the approximate values are 2.91 and 2.89

Step-by-step explanation:

The area of a quadrilateral is expressed as

A=L*B

Where L=length

B=breadth or width

I. e assuming it has two of its sides equal

Say given area is

A=L*B=8.4 square feet

Let's take the square root of the area A=2.898

=2.89

Approximately

L= 2.9 feet

Let's us divide the area by L to get B

8.4/2.9= 2.91

The perimeter of a rectangle is twice the sum of the dimensions:

Factor a^2−2ab−6by+3ay

a^2−2ab+3ay−6by

=(a−2b)(a+3y)

Answer:

(a−2b)(a+3y)

the factored expression is:

a(a + y) - 2b(a + 3y)

We can factor the expression [tex]a^2-2ab-6by+ay[/tex] using a combination of grouping and factoring by difference of squares:

We can group the terms based on common factors:

[tex](a^2 + ay) - (2ab + 6by)[/tex]

In the first group, a is the common factor: a(a + y)

In the second group, 2b is the common factor: 2b(a + 3y)

Then we combine the terms

a(a + y) - 2b(a + 3y)

Therefore, the factored expression is:

a(a + y) - 2b(a + 3y)

we know that

[tex]I=Prt[/tex]

where

I is the amount in interest

P is the investment

r is the interest rate

t is the time in years

Solve for t

[tex]t=I/(Pr)[/tex]

we have

[tex]I=\$1,400\\ P=\$27,000\\ r=4.2\%=0.042[/tex]

substitute

[tex]t=1,400/(27,000*0.042)=1.23\ years[/tex]

therefore

the answer is

[tex]1.23\ years[/tex]

Answer: The probability lies between 0 and 1

Step-by-step explanation:

As from the given information probability of an event lies between 0% to 100% .

To convert percent into integer or fraction we have to divide it by 100

[tex] 0\%= \frac{0}{100} = 0 [/tex]

And

[tex] 100\% = \frac{100}{100} = 1 [/tex]

From the above the probability of an event lie between integers 0 to 1.

To find the total change in the number of bushels the farmer has for sale after 5 days, multiply the average number of bushels sold per day by the number of days.

To find the total change in the number of bushels the farmer has for sale after 5 days, we need to multiply the average number of bushels sold per day by the number of days.

The average number of bushels sold per day is 16 and three fourths, which can be written as 16.75.

Multiplying 16.75 by 5 gives us the total change in bushels after 5 days, which is 83.75 bushels.

The fraction 7/9 converts to the decimal 0.77777778, which is a repeating decimal as the digit '7' repeats infinitely.

To convert the fraction 7/9 to a decimal, divide 7 by 9. So, when you divide 7 by 9, the answer you get is 0.77777778. This decimal does not terminate (come to an end after a specific number of decimal spaces), instead it repeats. Specifically, the digit '7' repeats indefinitely, so we can say its a repeating decimal.

As an example, if you consider 1/2, when you divide 1 by 2 it gives 0.5, which is a decimal that terminates. However, in our case - when we divided 7 by 9 it gave us 0.77777778 which repeats, hence it is a repeating decimal, not a terminating decimal. This is the key difference between repeating and terminating decimals.

box number six: definition of a right triangle

just took the test and these are the correct answers, hope i helped :)

Solution:

Given : ∠ D E G= 51°, ∠GEF=39°

To prove: Δ D E F is a right triangle.

Proof:

A right angle triangle D E F.

∠ D E F =90°.

Point G is on segment D F, and segment E G is drawn.

Now, taking ∠DEG and ∠GEF into consideration,

∠DEG=51° and ∠GEF=39°→→(Given)

∠DEG + ∠GEF =

∠DEF=51° + 39°

∠DEF=90°,showing Triangle D E F is a right triangle.

to test the points, substitute the x-coordinate into the equation and if the value of y equals the y-coordinate then the point lies on the graph

(0, [tex]\frac{1}{2}[/tex]) → y = 0 + [tex]\frac{3}{4}[/tex] = [tex]\frac{3}{4}[/tex] ≠ [tex]\frac{1}{2}[/tex]

(0 , [tex]\frac{3}{4}[/tex]) → y = [tex]\frac{3}{4}[/tex] ← on graph

([tex]\frac{3}{4}[/tex], 0) → y = [tex]\frac{3}{8}[/tex] + [tex]\frac{3}{4}[/tex] ≠ 0

([tex]\frac{3}{4}[/tex],[tex]\frac{1}{2}[/tex] → y = [tex]\frac{3}{8}[/tex] + [tex]\frac{3}{4}[/tex] ≠ [tex]\frac{1}{2}[/tex]

([tex]\frac{1}{2}[/tex], 1) → y = [tex]\frac{1}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 1 ← on graph

the points (0, [tex]\frac{3}{4}[/tex]) and ([tex]\frac{1}{2}[/tex], 1) are on the graph

The points that are contained in the graph of the straight line y = (1/2)x + 3/4 are (0,3/4) and (1/2,1).

An equation describes that both sides of the variables and constants are in different forms but they are equal.

To determine if each given point is contained in the graph of the equation Y = (1/2)x + 3/4 we will put the values of x in the equation and determine the corresponding value of y.

When x = 0, y = (3/4).

When x = (3/4), y = 9/8.

When x = 1/2, y = 1.

So, the points that are contained in the graph Y = (1/2)x + 3/4 are (0,3/4), (1/2,1).

"·" - product

"+" - sum

x² - square of x

Answer: x · (6 + 8 · x²) = x(6 + 8x²)

The expression "the product of x and the sum of 6 and 8 times the square of x" can be written as [tex]\( x \cdot (6 + 8x^2) \)[/tex].

The mathematical expression "the product of x and the sum of 6 and 8 times the square of x" is represented as [tex]\( x \cdot (6 + 8x^2) \)[/tex]. To simplify, distribute x into the parentheses, yielding 6x + 8x^3. This expression captures the specified operation, where x is multiplied by the sum of 6 and 8 times the square of x.

It is essential to follow the order of operations, ensuring that the square of x is calculated first, then multiplied by 8, and finally added to 6 before multiplying the result by x. This expression forms the algebraic representation of the described mathematical operation.

1 + 4x = -5 + 7x

1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:

1+5=7x-4x

2nd step:

3x=6

3rd step: you need to divide both sides into 3, because it is the common divisor.

x=2

1 + 4x = -5+7x

7x - 4x = 1 + 5

3x = 6

If you are just dividing percent's, then each grade would have 12.5 percent.

Total investment is =$58500

Annual income produced = $3795

Rate of one investment = 5%

Rate of second investment = 7%

Let the amount invested at 5% be = x

Then, amount invested at 7% rate will be = [tex]58500-x[/tex]

The equation becomes:

5%x + 7%(58500-x) = 3795

= 0.05x + 0.07(58500-x) = 3795

0.05x + 4095 - 0.07x = 3795

0.02x = 300

x = 15000

Hence,  the amount invested at 5% is = $15000

Amount invested at 7% = 58500-15000 = $43500

This is a simultaneous equation in [tex]x[/tex] and [tex]x[/tex].

But the coefficient of [tex]x[/tex] in the second equation is zero. that is why it seems to be absent.

We solve these two equations simultaneously

by putting [tex]y=2[/tex] in to equation (1).
