first person to answer will get brainliest.

Answer:

4140 pieces

Step-by-step explanation:

This is true because we would have to multiply the number of jigsaw puzzles and how many pieces each on of them had to see how many pieces they put together in all.

To set up the equation we would do 345 times 12,

if you calculate it, the answer would be 4140.

Hopes this helps, and good luck!! :)

Answer:

aquí es cómo

Step-by-step explanation:

Convertir el número decimal a fracción colocándolo sobre una potencia de diez. Como hay 2 números a la derecha del punto decimal, coloque el número decimal sobre 10 ^ 2 (100). Luego, agregue el número entero a la izquierda del decimal.

espero que esto ayude.

Answer:

13 men's.........

.........

.......

One single men is needed to clear the entire man.

Given is that a farmer needs 5 men to clear his farm in 10 days.

Assume that the [x] men are needed to clear the bush in 2 days.

In 10 days, 5 men can clear the farm.

In 1 day, (5/10) men can clear the farm.

In 2 days -

{x} = (5/10 x 2) men

{x} = 1 men

Therefore, one single men is needed to clear the entire man.

Answer: the transformation of ABC to MNO preserves both side lengths and angle measures of the triangle.

Step-by-step explanation:

Answer:

B - The transformation of triangle ABC to triangle MNO preserves both the side lengths and angle measures of the triangle.

Answer:

20, 60, 100

Step-by-step explanation:

Since the angles in a triangle add up to 180 degrees, we can change the statement by saying x+3x+5x = 180 degrees. That would mean that 9x is equal to 180, and 180/9=20. 20 times 5 is 100, and 20 times 3 is 60.

Hi!

Your answer will be: 8,000.

hope this helps!

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

[tex]k = 59(f - 32) + 273.15[/tex]

Subtract the sides of the equation minus -273.15

[tex]k - 273.15 = 59(f - 32)[/tex]

Divided the sides of the equation by 59

[tex] \frac{k - 273.15}{59} = \frac{59}{59} (f - 32) \\ [/tex]

[tex] \frac{k - 273.15}{59} = f - 32 \\ [/tex]

Subtract the sides of the equation plus 32

[tex] \frac{k - 273.15}{59} + 32 = f \\ [/tex]

And we're done.

Thanks for watching buddy good luck.

Answer: 3x-4y=12

Step-by-step explanation:

Answer:

k = -3

Step-by-step explanation:

Step 1: Write equation

11 = -3k - 22 - 8k

Step 2: Solve for x

Step 3: Check

Plug in k to verify it's a solution.

11 = -3(-3) - 22 - 8(-3)

11 = 9 - 22 + 24

11 = -13 + 24

11 = 11

Answer:64

Step-by-step explanation:

2*2*2*2=4*4=16. 16*16*16=4,096. 2*2*2*2*2*2=4*4*4=64. 4,096/64=64.

Answer:

Fifth Score = 87

Sixth Score = 95

Step-by-step explanation:

Given

[tex]Average = 85[/tex]

[tex]Scores = 83, 78, 87, 80[/tex]

[tex]Fifth\ score = x[/tex]

[tex]Sixth\ Score = 8 + x[/tex]

Required

Set up an equation

Solve for the fifth and sixth score

Average is calculated as thus:

[tex]Average = \frac{\sum x}{n}[/tex]

[tex]Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]

Substitute 85 for Average

[tex]85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]

[tex]85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}[/tex]

[tex]85 = \frac{336+ 2x}{6}[/tex]

Multiply both sides by 6

[tex]85 * 6 = 336 + 2x[/tex]

[tex]510= 336 + 2x[/tex]

Solve for 2x

[tex]2x = 510 - 336[/tex]

[tex]2x = 174[/tex]

Solve for x

[tex]x = 174/2[/tex]

[tex]x = 87[/tex]

Hence:

[tex]Fifth\ Score = 87[/tex]

[tex]Sixth\ Score = 87 + 8[/tex]

[tex]Sixth\ Score = 95[/tex]

Answer:

D is correct

Step-by-step explanation:

Here, we want to select which of the options is correct.

The correct option is the option D

Since the die is unfair, we expect that the probability of each of the numbers turning up

will not be equal.

However, we should also expect that if we add the chances of all the numbers occurring together, then the total probability should be equal to 1. But this does not work in this case;

In this case, adding all the probabilities together, we have;

1/12 + 1/12 + 1/12 + 1/12 + 1/12 + 1/2

= 5(1/12) + 1/2 = 5/12 + 1/2 = 11/12

11/12 is not equal to 1 and thus the probability distribution cannot be correct

Answer:

a. [tex] p = 2\pi r + 8r [/tex]

b. [tex] r = \frac{p}{2\pi + 8} [/tex]

Step-by-step explanation:

a. Radius of semicircle (r) = r

Diameter of semicircle (d) = 2r

Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r

Distance around the track (p) = circumference of circle + 2(l)

Note: the two semicircles of the track = 1 full circle

Circumference of full circle = πd = π*2r = 2πr

Distance around the track:

p = 2πr + 2(4r)

p = 2πr + 8r

b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.

[tex] p = 2\pi r + 8r [/tex]

Factor out r

[tex] p = r(2\pi + 8) [/tex]

Divide both sides by (2π + 8)

[tex] \frac{p}{2\pi + 8} = \frac{r(2\pi + 8)}{2\pi + 8} [/tex]

[tex] \frac{p}{2\pi + 8} = r [/tex]

[tex] r = \frac{p}{2\pi + 8} [/tex]

Answer:

Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.

Step-by-step explanation:

From Function theory we get that range of a function is the set of values of [tex]y[/tex] so that exist a respective value of [tex]x[/tex], whose set is the domain of the function. Let be [tex]f(x) = (x+1)^{2}[/tex] and [tex]g(x) = -4\cdot |x+1|[/tex], the ranges of each function are, respectively:

f(x):

From Real Algebra we know that the square of every number is a non-negative number, which means that:

[tex](x+1)^{2} \geq 0[/tex]

[tex](x+1)^{2}-4 \geq -4[/tex] (Compatibility with addition)

[tex]f(x) \geq -4[/tex] (Definition/Result)

The range of [tex]f(x)[/tex] is: [tex]Ran \{f(x)\} = [-4, +\infty)[/tex]

g(x):

From Real Algebra we know that a absolute value leads to non-negative number, which means that:

[tex]|x+1|\geq 0[/tex]

[tex]-4\cdot |x+1| \leq 0[/tex] ([tex]a> b \longrightarrow a \cdot c < b\cdot c[/tex], if [tex]c < 0[/tex])

[tex]g(x) \leq 0[/tex] (Definition/Result)

The range of [tex]g(x)[/tex] is: [tex]Ran\{g(x)\} = (-\infty, 0][/tex]

If we compare each range, we came into the conclusion that:

[tex]-4 \leq y \leq 0[/tex].

Thus, correct answer is: Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.

Answer:2

Step-by-step explanation: Because the answer is 2 :)

Answer:

a) 0.011

b) 0.0032

Step-by-step explanation:

first lets say A₁ denotes the event that first inspector detects a flaw and A₂ is event that the law will be detected by the second inspector,

also let B denote the event that an item has a flaw.

a)

Given that;

P(B) = 0.1

so

P(A₁ / B ) = 0.9,  P(A₂ / B ) = 0.7

using Baye's rule, the probability that an item has a flaw if it was passed by the first inspector is;

P(B / A₁ⁿ ) =  [P(A₁ⁿ / B ) P(B)] / [ P(A₁ⁿ / B ) P(B) + P(A₁ⁿ / Bⁿ ) P(Bⁿ) ]

the probability that the first inspector will not detect the flaw if it actually exist is;

P(A₁ⁿ / B ) = 1 - P(A₁ / B )

= 1 - 0.9

= 0.1

Since there are no false detections, the probability that the first inspector will not detect the flaw, given that item does not have flaws is;

P(A₁ⁿ / Bⁿ ) = 1.0

so the probability that the item has flaw if it was passed by the first inspector is;

P(B / A₁ⁿ ) =  [(0.1) (0.1)] / [ (0.1 ) (0.1) + (1.0) (1 - 0.1) ]

= 0.01 / ( 0.01 + 0.9)

= 0.01 / 0.91

= 0.011

b)

Also by Bayes rule, the probability that the item has a flaw if it was passed by both inspectors is;

P(B / A₁ⁿ ∩ A₂ⁿ) =  [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B)] / [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B) + P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) P(Bⁿ)]

Now since inspectors function independently, the probability that both inspectors will not detect the flaw if it actually exists is;

P(A₁ⁿ ∩ A₂ⁿ / B) = P(A₁ⁿ / B) P(A₂ⁿ / B)

= ( 1 - 0.9 ) ( 1 - 0.7)

= 0.1 * 0.3

= 0.03

since there are no false detections, the probability that both inspectors will not detect the flaw, given that item does not have a flaw is;

P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) = 1.0

therefore

the probability that the item has a flaw if it was passed by both inspectors is;

P(B / A₁ⁿ ∩ A₂ⁿ) = [(0.03)(0.1)] / [(0.03)(0.1) + (1.0)(1-0.1)

= 0.003 / 0.93

= 0.0032
