Answer 2

Answer:

1/1/3 of a tree

Step-by-step explanation:

30 minutes = 2/3 of a tree

Since 1 hour = 60 minutes,

60 minutes = 2/3 × 2

                   = 4/3

                   = 1/1/3 of a tree

The fourth option is the answer.

Answer:

part #2 none are exactly correct... the terms go on forever, so 1 &2 are out...

the "difference" is definitely not the same, so three is out..

4 is the closest, but the ratio is not the same, there is a trend in the ratio..

this is the Fibonacci sequence, and the ratio trends toward the "golden ratio" ( φ -phi) but never is exactly φ because φ is irrational

Step-by-step explanation:

(I'm assuming you need to find the missing side of the triangle)

To find missing values in a right angle. we will use the pythagoras theorem which states that:

h^2 = a^2 + b^2

16^2 = 14^2 + b^2

256 = 196 + b^2

256 - 196 = b^2

60 = b^2 (take sqaure root)

b= 7.75

Answer from Gauthmath

Answer:

7.75

Step-by-step explanation:

*I’m a big starter to brainly so I’ll appreciate if I can get brainliest please thank you*

Solve the right triangle is a incomplete question. Instead the correct question should’ve been: “Solve for the missing side length”.

Two things we need to understand for this

• Pythagorean theorem
• A, b and c sides
——————————————————————

Pythagorean theorem: a formula used to solve for a missing side length.

Pythagorean theorem = a^2 + b^2 = c^2 where a^2 would be 14 b^2 would be missing side and c^2 would be 16.

Makes sense cause the two sides added (a^2 & b^2) add up to c^2 which is the largest side.

Now we’re going to get right into the steps!

Step 1. Find the missing side length of the right triangle

a^2 + b^2 = c^2

Substitute the side lengths to the formula

14^2 + b^2 = 16^2

Simplify the exponents

196 + b^2 = 256

Solve for b^2

b^2 = 256 - 196

b^2 = 60

Note: that’s not the final answer that is just side b being squared now to undo the square we must square root 60.

Sqrt rt 60 = 7.75

So the missing side length of the triangle would be 7.75

Supón que un obrero manufactura cajas rectangulares dedistintos tamaños. La longitud de cualquier caja debe ser superior a su ancho en al menos 3 cm, y el perímetro no puede ser superior a los 24 m. ¿Cuáles son las medidas posibles de una caja?

Answers

Answer:

Dado que un obrero manufactura cajas rectangulares de distintos tamaños, y la longitud de cualquier caja debe ser superior a su ancho en al menos 3 cm, y el perímetro no puede ser superior a los 24 cm, para determinar cuáles son las medidas posibles de una caja se debe realizar el siguiente cálculo:

X + X + 6 = 24

2X = 18

X = 9

Por lo tanto, la caja puede tener 4.5 centímetros de ancho por 7.5 de largo, o bien ir aumentando su longitud en desmedro de su anchura.

Answer:  Choice B)  [tex]\frac{y}{x} = \frac{2}{3}[/tex]

This is the same as saying  y/x = 2/3

Or I suppose you could say "y over x = two-thirds".

===============================================

Explanation:

Recall that slope is rise over run

slope = rise/run

The rise being the change in y, while the run is the change in x.

So we could informally think of it as slope = y/x

-----------

Since we're told that it "has a rise of 2 and run of 3", this means slope = 2/3.

The slope is both y/x and also 2/3.

Equating the two expressions leads us to y/x = 2/3. This is why choice B is the final answer.

This trick only works when the line goes through the origin (0,0)To rephrase the last bullet point, the line must have y intercept 0.If you multiplied both sides by x, then you get y = (2/3)x

identify each of the following as rational or irrational.

Answers

Answer:

Step-by-step explanation:

A rational number can be written as a fraction of two integers.

√23 is irrational because we do not know what the square root of 23 is in terms of integers in a fraction.

104.42 is rational because it can be expressed as 10442/100 . We can express it as this because

104.42 * 1 = 104.42 * 100/100 = 10442/100, and multiplying something by 1 keeps it the same

√64 is rational because it is equal to 8, and 8/1 is equal to 8

49.396 with the 6 repeating is rational because we can express 49.39 as

49.39 * 1 = 49.39 * 100/100 = 4939/100, and we are then left with

49.396- 49.39 = 0.006 (with the 6 repeating). A repeating decimal can be expressed as x/9, with the x representing all values before the repetition begins multiplied by 10.

For example, 0.6 with the 6 repeating can be represented as 6/9. This is because 0.6 * 10 = 6, and we divide that by 9. Similarly, 0.006 with the 6 repeating can be represented by 0.06/9

We add the two fractions together to get

4939/100 + 0.06/9

multiply both fractions by the other's denominator to even them out and make the numerator of the second fraction an integer

(4939*9)/(100*9) + (0.06*100)/(9*100)

= 44451/900 + 6/900

= 44460/900

Assuming that the last number has only the digits given, that is rational because, similarly to 104.42, it can be multiplied by a power of 10 to result in (integer)/(integer), making it rational. If the dots represent infinite digits, then it is not rational because there are infinite digits that are not repeating, and there is no way to know the last digit, so it is impossible to write a fraction from it

Tommy was going to buy a new lawn mower from Lawn Depot for $169, minus a 10% discount. He saw the same mower on sale at Mowers-R-Us. Their mower originally cost $210 and was on sale for ⅓ off. Determine the sale price of the mover at each store. Identify which store would be the most economical place to purchase the mover. Show your work.

Answers

Answer:

Sale price of first Mover = $ 152.1.

Sale price of second mover = $ 70

Mowers - R - Us store is economical place.

Step-by-step explanation:

Cost of first Mover = $ 169 and discount is 10%

Cost of second Mover = $ 210 and the sale is 1/3.

So, the effective cost of first Mover = $ 169 - 10 % of $ 169 = $ 169 - $ 16.9

= $152.1

So the effective cost of second Mover = 1/3 of $ 210 = $ 70

So, the second store is the economical place.  

what are the slope and the y-intercept of the linear function that is represented by the table?​

Answers

Slope is -2 and the y intercept is on the table where x is 0 so y intercept is 12
Answer:

The slope is -2, and the y-intercept is 12

Step-by-step explanation:

Slope = y2 - y1 / x2 - x1

Slope = 18 - 12/ -3 - 0

Slope = 6/-3

Slope = - 6/3

Slope = -2

So the slope is -2

When x was 0 y intercept was 12. Therefore, y-intercept = 12

y-intercept = 12

Cosine is the x-coordinate in our orderes pairs. If our point ends up on the right side of the y-axis, the cosine will be positive. If our point ends up on left side, it will be negative.

Choose a thetha (I'm going to choose it in degrees) in the first quadrant to help with a visual.

If theta=70:

1) then 180-70=110 which is in second quadrant, so our cosines will be opposite in value.

2) then 180+70=250 which is in third quadrant, so our cosines will be opposite in value.

3) then 4×180-70=720-70=650 =1(360)+290 which ends up in the 4th quadrant which means the consines will have the same value.

The proportion of 1s received at the end of the channel is of 0.598.

For each bit receive, 0.01 probability of an error, so 0.99 probability it is correct.

a. What is the proportion of 1s received at the end of the channel?

99% of 60%(sent 1s, received 1).

1% of 40%(sent 0s, received 1). So
