Answer:

2

Step-by-step explanation:

a=1 and b=3

\frac{2ab+2}{2ab-2}

\frac{2(1)(3)+2}{2(1)(3)-2}

\frac{6+2}{6-2}

\frac{8}{4} =\frac{2}{1} =2

A path is 0.75 m wide. Mr. Kassel extends the width by placing blocks 20 cm wide on each side of the pathl. What is the new widt
Nuetrik [128]
We know that there are 100 cm in 1 m. We can convert 0.75 m to cm by multiplying by 100 to give us:

0.75m*100=75cm

Therefore the path before the addition is 75 cm wide.

Mr. Kassel added 20 cm of blocks on each side of the path, meaning that the added width is actually 40 cm total (20 on each side, and there are 2 sides).

So we need to add 40 cm to the original 75 cm:

40cm+75cm=115cm

So now we have the width of the path in cm, the question asks for the width in meters. We can do this by dividing the width in cm by 100 to get the width in meters:

\frac{115cm}{100}=1.15m

Now we know that the new width of the path is 1.15 m.

Hay 12 canicas en una bolsa y 6
Genrish500 [490]

Answer:

50%.

Step-by-step explanation:

Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:

6 / 12 = X

0.5 = X

0.5 = 50/100

50/100 = 50%

Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.

The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.
suter [353]

we conclude that the correct option is A, the slope is:

<em>"the average number of pounds per foot tall"</em>

<h3>What does the slope of the line represent?</h3>

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"
