ABCD is a rectangle. Which of the following pairs of angles are complementery?

C.

Any number that is over the denominator 9, will be repeating it self.

Answer:

Part 1) The units rates are

A) [tex]0.1165\frac{\$}{oz}[/tex]

B) [tex]0.1656\frac{\$}{oz}[/tex]

C) [tex]0.0516\frac{\$}{oz}[/tex]

D) [tex]0.0579\frac{\$}{oz}[/tex]

Part 2) The best buy is the size 48 1/4 oz

Step-by-step explanation:

we know that

To find out the unit rate divide the total cost by the total volume

Part 1) Calculate the unit rate for each size

case A) we have

8 1/2 ounce bottle costs $0.99

Convert mixed number to an improper fraction

[tex]8\frac{1}{2} =\frac{8*2+1}{2}=\frac{17}{2}\ oz[/tex]

Find the unit rate

[tex]\frac{0.99}{(17/2)}= 0.1165\frac{\$}{oz}[/tex]

case B) we have

18 2/2 oz. bottle costs $1.49

Convert mixed number

[tex]18\frac{2}{2} =18+1=19\ oz[/tex]

Find the unit rate

[tex]\frac{1.49}{19}= 0.1656\frac{\$}{oz}[/tex]

case C) we have

48 1/4 oz. carton costs $2.49

Convert mixed number to an improper fraction

[tex]48\frac{1}{4} =\frac{48*4+1}{4}=\frac{193}{4}\ oz[/tex]

Find the unit rate

[tex]\frac{2.49}{(193/4)}= 0.0516\frac{\$}{oz}[/tex]

case D) we have

64 3/4 oz. carton costs $3.75

Convert mixed number to an improper fraction

[tex]64\frac{3}{4} =\frac{64*4+3}{4}=\frac{259}{4}\ oz[/tex]

Find the unit rate

[tex]\frac{3.75}{(259/4)}= 0.0579\frac{\$}{oz}[/tex]

Part 2) which size is the best buy

we know that

The best buy is the one with the smallest unit rate

so

[tex]0.0516\frac{\$}{oz}[/tex]

The best buy is the size 48 1/4 oz

Hello!

So, to answer this question we need to note that quadruple = x4

25 (our initial count) x 4 = 100

100 (after one hour) x 4 = 400

400 (after two hours) x 4 = 1600

1600 (after three hours) x 4 = 6400

6400 (after four hours) x 4 = 25600

25600 (after five hours) x 4 = 102400

So to answer your question, after six hours, there will be 102,400 of that bacteria in the jar.

Hope this helps!

the answer will be  is V=8/t

By definition an irrational number is one that is not rational. Therefore, it is not possible for a number to both rational and irrational.

Answer:

|2a|

Step-by-step explanation:

Note that distance is positive.  a less -a comes out to +2a, which is the distance between and -a.

f(x) = (x - 4 )(x - 6) = 0

because you can see when each factor is equal to zero

x - 4 = 0 ⇒ x = 4

x - 6 = 0 ⇒ x = 6

Hi,

all of them multiplied together is 480.

1x8=8

8x5=40

40x2=80

Answer: 480

Step-by-step explanation:

Since commutative property can be used for multiplication, rewrite it as:

(1 x 8) x (5 x 12)

= 8  x  60

= 480

Its not clearly given that whether EBF = 2x + 9 or 2x - 9.

I have written the solution for both.

If EBF = 2x + 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x + 9)

           = (6x + 2x) + (26 + 9)

           = 8x + 35

11x - 8x = 35 + 31

3x = 66

x = 22

Therefore, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°

If EBF = 2x - 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x - 9)

           = (6x + 2x) + (26 - 9)

           = 8x + 17

11x - 8x = 17 + 31

3x = 48

x = 16

Therefore, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

The expression for angle ABF:  ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

From the question: If EBF = 2x + 9, then ABF = 6x + 26 and ABE = 11x - 31.

When, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x + 9)

          = (6x + 2x) + (26 + 9)

          = 8x + 35

11x - 8x = 35 + 31

3x = 66

x = 22

Hence, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°

When EBF = 2x - 9,

So, ABF = 6x + 26 and ABE = 11x - 31.

When, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x - 9)

          = (6x + 2x) + (26 - 9)

          = 8x + 17

11x - 8x = 17 + 31

3x = 48

x = 16

So,  ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

3.2c+1.7=24.1

First subtract 1.7 from both sides

3.2c=22.4

Now divide both sides by 3.2

c=7

Now put it in the equation.

3.2(7)+1.7=24.1

3.2c + 1.7 = 24.1'

c = (24.1 - 1.7) : 3.2

c = 22.4 : 3.2

Answer:

325 hamburgers were sold on Thursday.

Step-by-step explanation:

Let h be the number of hamburgers and c be the number of cheeseburgers.

Using this information we can set up two equation as:

[tex]h+c=593\\c=h-57[/tex]

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

[tex]h+h-57=593\\2h-57=593\\2h=650\\h=325[/tex]

Therefore, the number of hamburgers sold on Thursday were 325.

Answer: It is best solve using elimination method

Step-by-step explanation:

4x + y = 1 --------(1)

2x + y = 8---------(2)

subtract (2) from (1)

2x = -7

divide bothside by 2

2x/2 = -7/2

x= -7/2

we can substitute x = -7/2 in any of the equations.

Lets take equation (1)

4x + y = 1

4(-7/2) + y =1

2(-7) + y = 1

-14 + y = 1

y = 1+14

y =15

Answer:

{x | x = 0.5 or x = 4.5}

Explanation:

Before we begin, remember that:

The modulus gives the positive value of what's inside it.

This means that:

|a| = |-a| = a

Now, for the given, we have:

|2x-5| = 4

From the above rule, we can deduce that:

either:

2x - 5 = 4

2x = 4 + 5 = 9

x = 4.5 ............> first solution

Or:

2x - 5 = -4

2x = 5-4 = 1

x = 0.5 ..........> second solution

Now, we check:

at x = 4.5: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified

at x = 0.5: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified

Hope this helps :)

Without knowing the ages of all the different members of the club, I believe that the mean would go down due to 24 being an outlier. You generally take the mean by adding up all the numbers and dividing by all the # of given values. Outliers such as 24 would skew the results leaning none way or the other, in this case making it lower than the previous mean.

Step-by-step explanation:

If x=3+bi, then

[tex]|x|=\sqrt{3^2+b^2}.[/tex]

You know that [tex]|x|^2=13,[/tex] then

[tex]\left(\sqrt{3^2+b^2}\right)^2=13,\\ \\ 9+b^2=13,\\ \\b^2=4,\\ \\b=\pm 2.[/tex]

Two possible complex numbers satisfy these conditions:

[tex]x_1=3+2i, \ x_2=3-2i.[/tex]

As you can see the possible value of b is 2.

Answer: correct choice is A.

The possible value of b in the given complex number is 2 (Option A). This is found by using the definition of modulus of a complex number and solving the resulting equation.

This question requires understanding of complex numbers and their modulus. A complex number is a number of the form a + bi, where a and b are real numbers and i is the imaginary unit with the property i^2 = -1.

|x|^2 represents the square of the modulus (or absolute value) of the complex number x which is defined as |x|^2 = a^2 + b^2. Given in the question, x = 3 + bi and |x|^2 = 13. Thus, by substitution, we get 13 = 3^2 + b^2.

Performing arithmetic operations, it's equivalent to b^2 = 13 - 3^2 = 4. To solve for b, we take the square root of both sides. Because b can be positive or negative, we get b = ±2. Therefore, from the options given, the possible value of b is 2 (Option A).

Write an expression that shows how to use the halving and doubling strategy to find 28x50

Halving strategy means we divide by 2

Doubling strategy means we multiply by 2

We apply halving strategy for 28 and doubling strategy for 50

Half of 28 is 14

Double of 50 is 100

So 14 * 100 = 1400

Now we check with 28 * 50

28 x 50 = 1400

So required expression is
