Answer:

13/12 or 1  1/12

Step-by-step explanation:

First you change 2/3 to 8/12 by multiply both the numerator and denominator by 4. Then, you add the numerators but DO NOT change the denominators. Therefore, your answer is 13/12 which = 1  1/12.

se necesita llenar un galon de agua,en 2 litros se tarda 30 minutos.cuantos litros me hacen falta para completar el galon y cual
mariarad [96]

Answer: 1.78 L are needed to complete the gallon and it will take 29.66 min to completely fill it

Step-by-step explanation:

The question in english is:

A gallon of water needs to be filled, in 2 liters it takes 30 minutes. How many liters do I need to complete the gallon and what is the time it takes me to fill it?

We know 1 gallon is equal to 3.78 liters:

1 gal=3.78 L

In addition, we are told you have filled the gallon with 2 L at a rate of \frac{2 L}{30 min}=0.06 L/min.

So, if we want to know how many liters are left to completely fill the gallon, we have to sbstract the 2 L to the total amount of a gallon:

3.78 L-2 L=1.78 L This is the amount you need to complete the gallon

On the other hand, the rate is defined as:

rate=\frac{Liters}{time}

Isolating time:

time=\frac{Liters}{rate}

Then, if we input the 1.78 L we need to fill the gallon we will have the time:

time=\frac{1.78 L}{0.06 L/min}

time=29.66 min This is the time you need to fill the gallon

Alright, let's convert to decimals for these calculations: fractions could get messy.
1/5 = .2
1/2 = .5

Imagine a rectangular solid in your mind. How many sides does it have?
6. In the image shown you have 3 facing you. In addition to those, there are 3 not shown. They will correspond to the calculations you make on the front, though, so all you have to do is double the values you get.

Area is length * width, or length * height, or width * height. So:
A = 3.2 (length) * 4.5 (height) for the front face of the rectangular solid(as well as the back face.)
A = 5 (width) * 4.5 (height) for the right face of the rectangular solid (and the one on the left, away from you.)
A = 3.2 (length) * 5 (width) for the top of the solid(and the bottom).

Calculating these values, we get that 
A=14.4
A=22.5
A= 16
So that's 3 out of 6 values for the full surface area.
Like I said though, these values can merely be doubled for the complete area.
Add these three together:
14.4+22.5+16=52.9
multiply by 2 to account for the other 3 sides
52.9 * 2 = 105.8
105.8 is the surface area.

The midpoint of FG is M( -1, 3). One endpoint is F(-2,5). Find the coordinates of Endpoint G
Mice21 [21]

Answer:

Step-by-step explanation:

mid point is basically the mean of the x coordiante and the y coordinate. that means that the x coordinate in M, whihc is -1, is the mean of the x coordinate in F and G. the x coordinate in F is -2, so that means that the x coordinate og G must be 0, because 0+(-2) / 2 = -1       so -1 is the x coordinate of G.

To find the y coordinate of G, do the exact same thing. the y coordinate of M is 3, and the y coordinate of F is 5, which means that the Y coordinate of G must be 1. so the points for G are:

(-1,1)
