The reading rate for each of the students are 186.975, 225.0625, 209.94 and 189.64 pages per minute.

First of all, we would determine the number of words in each page of this 325-page book as follows:

Number of words = 90,000/325

Number of words = 276.92 ≈ 277 words per page.

For Jamie's reading rate, we have:

Jamie = (277 × 81)/120

Jamie's reading rate = 186.975 pages per minute.

For Molly's reading rate, we have:

Molly = (277 × 65)/80

Molly's reading rate = 225.0625 pages per minute.

For Edgar's reading rate, we have:

Edgar = (277 × 72)/95

Edgar's reading rate = 209.94 pages per minute.

For Tyrone's reading rate, we have:

Tyrone = (277 × 89)/130

Tyrone's reading rate = 189.64 pages per minute.

Answer:

During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.

Answer:

11cm

Step-by-step explanation:

Hi, I can help.

Now to find this it is just simple subtraction but you need to know what to look for.

Let us first imagine that the top rectangle sticking out doesn't exist. Lets focus on the bottom rectangle who has the dimensions of 6 and 18cm. We need to find the ? on the top of the rectangle.

Now lets add the top rectangle. Something important to remember is that the 5cm top lines up with the ? even though it is above it.

Also, the top and bottom of a rectangle is always to going to match up / be equal.

So the 5cm + ? is going to be equal to 16cm.

So how can we use this info to find the answer? We can actually look at the 16cm and 5cm. Since the 16cm and the 5 + ? are equal we can take the 16cm at the bottom and actually take away 5cm away from it to find the ?.

So :

16cm - 5cm = 11cm

So literally that is it.

11cm is your ?

I feel like I didn't do a great job explaining this so if you have any questions AT ALL please comment or message me and I will help you anywhere its needed. :)

5Answer:

Step-by-step explanation:

 Let the first session be y =20 + 30x .................. equation 1

 Let the second session be y = 10 + 35x .............. equation 2

equate the two functions

20 + 30x = 10 + 35x

y = 20 - 10 +30x - 35x

y = 10 -5x

Find the y intercept (that is where y = 0)

10-5x = 0

5x =10

x = 2

substitute x = 2 into equation 1 and 2

y =20 + 30(2) = 80

y = 10 + 35(2) =80

Notice that when you plot the graph for equ. 1 and equ. 2 , it intercepts at x =2 and y =80 (2, 80)

Answer:

If you add up the amount of pencils there are then you get 20,

so that means that you have 20 pencils in all, and out of the 20 pencils, 4 of them are green so the probability is 4/20

and 4/20 in decimal form is 0.2, so the probability is unlikely that she will pick a green pencil

Answer:

78 inches

Step-by-step explanation:

Well if we are assuming that the 60 inches and 50 inches are straight then we can use the Pythagorean theorem to do a^2 + b^2 = c^2, so  so a=60 and b=50. so we do that we get 6100, and if we find the square root of that it will be about 78.1024, and that rounded is 78.

Answer:

Step-by-step explanation:

Answer:

Isn't that just soild liquid and gas atoms?

The image is showing how the atoms change depending on which state of matter it is, so if it is a soild the atoms would be really compacted as it moves slower, if it's a liquid then it's more looser than a soild, but more compacted than a gas, and a gas is just moving a lot and has a lot more space.

^^ That would be the answer if you on the states of matter or something like that unit.
