Digiron [165]3 years ago

Answer:

the person entering the room is 10 years old

Step-by-step explanation:

x / 5 = 40

x = 40 * 5

x = 200

so the total of all the ages of 5 people is 200

x/ 6 = 35

x = 35 * 6

x = 210

the total of all the ages of 6 people would have to be 210 for there to be a mean age of 35

therefore, a ten year old kid entering the room, will make up the difference

What is the slope?<br><br> A) 3/7<br> B) 7/3<br> C) -3/7<br> D) -7/3
Brut [27]

Answer:

B) 7/3

Step-by-step explanation:

To find the slope of a line using a graph, locate two points. In this example, the points are (0, -2) and (3, 5).

Then, find the distance between the two points. To do so in this example, find the difference between 0 and 3, and -2 and 5.

3 - 0 = 3

5 - (-2) = 7

Since we're dealing with slope, the answer will be in y/x form. 7 is the distance between the y-coordinates and 3 is the difference between the x-coordinates, the answer is 7/3.

An insect crawls 30 inches in 16.3 minutes. If
omeli [17]

Answer:

Step-by-step explanation:

Convert 6 hours to minutes so that 6 hours and 16. 3 minutes can be in the same units.

Since 1 hour = 60 minutes, then 6 hours = 6 x 60 minutes = 360 minutes

Since the insect has more minutes to crawl (360 minutes), then we expect more inches to be covered. Therefore, the ratio is 360 minutes to 16.3 minutes

= 360 minutes : 16.3 minutes

= 360 : 16.3  

Now express the ratio as fraction and relate it with 30 inches

= 360/16.3  x  30/1

= 10800/16.3

= 662 .576687 and this is approximately 650 inches

Answer  = 650 = (C)
