Why is 2/10 equivalent to 1/5?

Answers

Answer 1

Answer:

If you divide both top and bottom of [tex]\frac{2}{10}[/tex] by 2, you get [tex]\frac{1}{5}[/tex]

Answer 2

Answer:

because you have to find common denominators

2/10= 1/5

2/10= 1x2/5x2

Whatever you do to the bottom, you do to the top so that is why i also multiplied the numerator by 2.

2/10=2/10

Find the angles:
m∠A = 2/3x°
m∠P = 4/5x°
∠A and ∠P are supplementary.

Answers

9514 1404 393

Answer:

  m∠A = 81 9/11°

  m∠P = 98 2/11°

Step-by-step explanation:

Supplementary angles have a total of 180°, so we have ...

  m∠A +m∠P = 180°

  2/3x° +4/5x° = 180°

  22/15x° = 180°

  x = 122 8/11 . . . . . . multiply by 15/22

Then the angles are ...

  m∠A = (2/3)(122 8/11)°

  m∠A = 81 9/11°

  m∠P = (4/5)(122 8/11)°

  m∠P = 98 2/11°

_____

Alternate solution

The fraction of 180° that is ∠A is ...

  (2/3x°)/(2/3x° +4/5x°) = (10/15)/(10/15 +12/15) = 10/22 = 5/11

  m∠A = (5/11)(180°) = 81 9/11°

  m∠P = 180° -m∠A = 98 2/11°

Answer:

m∡A = 81.8°

m∡P = 98.2°

Step-by-step explanation:

2/3x + 4/5x = 180

multiply each side by 15 to eliminate fractions

10x + 12x = 2700

22x = 2700

x = 122.7

∡A = 2/3 (122.7) = 81.8

∡P = 4/5 (122.7) = 98.2

Sharron bought some Flibbertigibbets and some
Whatchamajiggers. She bought 16 total items for a total of $42.
Flibbertigibbets cost $2 each, and Whatchamajiggers cost $4 each.
How many Flibbertigibbets did she buy? How many Watchamajiggers did she buy?

Answers

Answer:

She bought 11 Flibbertigibbets

and

5 Watchamajiggers

Step-by-step explanation:

Create a system of equations where x is fibbertigibbets and y is whatchamajiggers.

x+y=16
2x+4y=42

Now solve the system

y=16-x
2x+4y=42

Use the substitution method:

2x+4(16-x)=42
2x+64-4x=42
-2x=-22
x=11

Plug this back into either equation to solve for y:

x+y=16
11+y=16
y=5

So x=11 and y=5, meaning there are 11 fibbertigibbets and 5 watchamajiggers.

Is the new jar smaller, the same size or larger than the original?

Answers

Answer:

Step-by-step explanation:

Example: say the original size is 100

increasing 100 by 1/5 is the same as increasing 100 by 20, so the new size is 120

reducing 120 by 1/5 is the same as reducing 120 by 24, so now the new size is  96.

solve the iniquality 6x - 8 > 4x + 26

Answers

Answer:

x > 17

Step-by-step explanation:

Add 8 to both sides:

6x - 8 > 4x + 26

6x > 4x + 34

Subtract 4x from both sides:

2x > 34

Divide each side by 2:

x > 17

So, the solution is x > 17

Solution :

⇢ 6x - 8 > 4x + 26

⇢ 6x > 4x + 26 + 8

⇢ 6x > 4x + 34

⇢ 6x - 4x > 34

⇢ 2x > 34

⇢ x > 34/2

⇢ x > 17

Hence, solution is x > 17.

Your class is in groups, working on an induction worksheet. One of the questions asks to prove that if n is even, then 8n is also even. Your group proves it, but you're then asked if the converse is also true. Your classmate suggests that it is. What would you say to explain how this suggestion is flawed, and how would you help correct them

Answers

Answer:

The answer is "this statement is not true".

Step-by-step explanation:

It is true because it can be achieved by using the initiation method. (Or at even a look, as n is still n=2m for the whole m, and the same number is 8n=8* (2*m)=2*(8*m). So it's confirmed !! )

Now the opposite declaration says, "If 8n would be an even amount then n is an even number", that's why the statement is not true.

An easy way of demonstrating why an argument also isn't valid is to show an example it against. Take into consideration the 24. 24=8*3. i.e. the shape is 8n, where it is n=3. Of course, 24 is also an equivalent number, but n=3 is an odd number here. So, we at least this one event, wherein the opposite statement could be sustained. (q.e.d).  

Note:- "8n would be an even number per each integer n." is true since 8n=2*(4n), even for all integer n.

Sarah Sandoval is a coffee farmer trying to decide how many tons of coffee to produce. She can sell each ton of coffee for $2,400. The cost of producing her first ton of coffee is $600, and the second ton costs $1,200. Each additional ton of coffee costs $600 more to produce. How many tons of coffee should Sarah produce, and what is the total cost of her coffee production

Answers

Answer:

Sarah should produce four tons of coffee and total cost for four ton is $6,000.

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Selling price per ton = $2,400

Cost of production is increasing by $600 for each ton.

So, Cost of production first ton = $600

Cost of production for second ton = $600 + $600 = $1,200

Similarly, Cost of production for third ton = $1,200 + $600 = 1,800

Cost of production of fourth ton = $1,800 + $600 = $2,400

Here, Sarah can produce coffee till selling price = cost of production.

As, cost of production of four ton = selling price, then Sarah can produce only four tons of coffee.

Total cost for four ton coffee = $600 + $1,200 + $1,800 + $2,400

= $6,000

Sarah can produce 4 tons of coffee and the total cost of the production is $6000 and this can be determined by using the arithmetic operations.

Given :

Sarah Sandoval is a coffee farmer trying to decide how many tons of coffee to produce.She can sell each ton of coffee for $2,400. The cost of producing her first ton of coffee is $600, and the second ton costs $1,200. Each additional ton of coffee costs $600 more to produce.

The following steps can be used in order to determine the total amount of coffee (in tons) should Sarah produce and the total cost of her coffee production:

Step 1 - Remember that Sarah can produce coffee unitil selling price is equal to the cost of production.

Step 2 - According to the given data, each additional ton of coffee costs $600 more to produce.

Step 3 - From the above steps, it can be concluded that Sarah can produce 4 tons of coffee because the cost of 4 tons of coffee is equal to the selling price.

[tex]600\times 4 = $2400[/tex]

Step 4 - So, the total cost of producing four tons of coffee is:

Solve for the angle x.

Answers

Answer:

x=45

Step-by-step explanation:

An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.

You then divide each side by 2 to get the x by itself which leaves you with x=45.

Answer:

if I did my math right it's 45 if not please fix me

Step-by-step explanation:

First thing is the the sides are congruent meant the angles have to be the same.

Next is the box indicates 90°.

Last thing is that every triangle is 180°

so if I did this right the equation is 2x+90=180

and using algebra in this you eliminate the 90 by subtract because - is the opposite of + which cancels itself and leaving the total with 90.

Then divide the 90 by 2 as it cancels out 2x leaving the answer with x=45

Answers

Answer:

y = 340e^0.0427276t ; 908

Step-by-step explanation:

Given that :

t = time in days since study began

Number of bacteria after 11 days = 544

y = number of bacteria at time t

Exponential growth model:

y = ae^rt

Where a = initial amount ; r = Growth rate

y = 544 ; t = 11 ; a = 340

544 = 340*e^11t

544/340 = e^11t

1.6 = e^11t

Take the In of both sides

In(1.6) = 11t

0.4700036 = 11t

t = 0.4700036 / 11

t = 0.0427276

y = 340e^0.0427276t

Number of bacteria after 23 days :

Using the formula above :

t = 23

y = 340e^0.0427276(23)

y = 340 * 2.6717529

y = 908.39600

y = 908

The required formula is [tex]y = 340e^{0.0427}[/tex]

908 bacteria are there 23 days after the beginning of the study .

Given that,

A certain culture of bacteria has a population of 340.

The population grows according to a continuous exponential growth model. After 11 days, there are 544 bacteria.

We have to find,

Write a formula relating y tot. Use exact expressions to fill in the missing parts of the formula.

How many bacteria are there 23 days after the beginning of the study.

According to the question,

Let t be the time (in days) since the beginning of the study,

And let y be the number of bacteria at time,

t = time in days since study began

Number of bacteria after 11 days = 544

y = number of bacteria at time t

Then,

Exponential growth model:

[tex]y = a.e^{rt}[/tex]

Where, a = initial amount ; r = Growth rate

y = 544 ; t = 11 ; a = 340

Then,

[tex]544 = 340.e^{11t}\\\\\dfrac{544}{340} = e^{11t}\\\\1.6 = e^{11t}\\\\Taking \ log \ on \ both \ sides,\\\\ln(1.6) = 11t\\\\0.47 = 11t \\\\t = \dfrac{0.47}{11}\\\\t = 0.0427[/tex]

The required formula is [tex]y = 340e^{0.0427}[/tex]

 

There 23 days after the beginning of the study Number of bacteria after 23 days :

[tex]y = 340e^{0.0427}[/tex]

Where, t = 23

[tex]y = 340e^{0.0427276(23)}\\\\y = 340 \times 2.6717529\\\\y = 908.39600\\\\y = 908[/tex]

A grid has lines at 90-degreree angles. There are 12 lines in one direction and 9 lines in the other direction. Lines that are parallel are 11 inches apart. What is the least number of 12in by 12in floor tiles needed to cover all of the line intersections of the grid? The tiles do not have too touch each other.

Answers

Answer:

70

Step-by-step explanation:

Given that:

There are twelve (12) lines in a direction and another nine 9 lines in another direction.

If we draw the above illustration out, we will realize that we will have 11 squares by 8 squares.

i.e these 11 squares are 11 inches apart.

Hence, the length of their grid = 11  inches × 11 inches = 121  inches²

Thus, for 12 in by 12 in tiles; we will have:

= [tex]\dfrac {121}{12}[/tex]

= [tex]10 \dfrac{1}{12}[/tex]

This implies that there are 10 files with just [tex]\dfrac{1}{2}[/tex] inch gap in length.

Similarly, for 8 squares and 11 inches apart;

The width = 8 inches × 11 inches = 88 inches²

Thus; the 12 in tiles needed = [tex]\dfrac{88}{12}[/tex]

= [tex]7 \dfrac{1}{3}[/tex]

It signifies that there are 7 tiles with [tex]\dfrac{1}{3}[/tex] inch gap in width.

Thus, the least number of tiles required = 10 × 7 = 70
