Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?

Answers

Answer:

2 1/10 boxes were missing.

Step-by-step explanation:

It is given that,

Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday

Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday

After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.

We need to find the no of boxes that are missing.

Total no of boxes packed on Tuesday and Wednesday,

[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]

Missing boxes :

[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]

Hence, 2 1/10 boxes were missing.

Which statements are always true regarding the
diagram? Select three options.
Omz5 + mz3 = mz4
Omz3 + mz4 + mz5 = 180°
Dmz5 + mz6 =180°
Dm2 + mz3 = mz6
Omz2 + mz3 + mz5 = 180°

Answers

Answer:

Step-by-step explanation:

m∠5 +m∠6 = 180° ( the angles form a line)

m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)

m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)

Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?

Answers

Answer:

2x - 5 = (1/2)

 

4x - 10           [multiply by 2]

 x - 10 = -13                 [subtract 3x from both sides]

  x = -3                        [add 10 to both sides]

Step-by-step explanation:

The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"

What is algebra?

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."

"Twice the value of a number" is simply 2x.

"Five less" is simply -5, so for the first part we have (2x-5)

Examine the second section next. "Three times four times more than one half the number."

"Three times the quantity" simply indicates "three times something."

4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."

So the second part is simply 3(4+x/2).

Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x = 34

Therefore, the required number would be 34.

Sean multiplied two numbers and the resulting product was an irrational number. If the first number was 7/3, which of the following could be the second number? Two apply. 3/7, 2pie, 1, square root of three

Answers

Answer: 2*pi and √3.

Step-by-step explanation:

We know that when we multiply a rational number different than zero and an irrational number, the product will be also an irrational number.

Then if one of the numbers for this case is 7/3 (A rational number), the other must be an irrational number.

The given options are:

3/7 (is a rational number, so this is not the correct option)

2*pi (pi is an irrational number, then 2*pi is also an irrational number)

Then (2*pi)*3/7 will be an irrational number.

1 (this is a rational number, then this is not the correct option)

√3 (This is an irrational number, then this will be a correct option)

Then the two correct options are:

2*pi and √3.

Which of the following is the value of PQ?

Answers

Answer:

Step-by-step explanation:

Answer:

B) 61

Step-by-step explanation:

QR = QS

3x + 16 = 7x - 24

16 + 24 = 7x - 3x

40 = 4x

x = 40/4

x = 10

substitute x=10 into PQ = 2x+41

PQ = 2(10) + 41

PQ = 20 + 41
