Answer: 7

35/7=5
84/7=12
21/7=3

5, 12, and 3 don’t have any common factors so 7 is the prime factor.

Lauren is reading a novel for English class. The data below shows the number of pages reads, y, in x hours.
strojnjashka [21]

Answer:

Choice B is correct

Step-by-step explanation:

The variable x represents the number of hours;

2, 4, 5, 7, 9

The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.

The y variable represents the number of pages read;

50, 100, 125, 175, 225

The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.

A chemist is conducting an experiment which involves a certain chemical reaction. He begins the experiment with 666 milliliters
Ket [755]

Answer:

8 Minutes

Step-by-step explanation:

since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.

666-562 = 104

Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.

104 / 13 = 8

Help needed ASAP will give BRAINLIEST
grin007 [14]

Answer:

C.

Step-by-step explanation:

Recall that the sum of the (3) interior angles of a triangle <em>must</em> equate to 180.

In other words:

(55)+(20)+(x)=180

Where x is our unknown angle. So, we need to solve for x.

On the left, add 55 and 20:

75+x=180

Subtract 75 from both sides. The left side cancels:

x=105

Therefore, the third angle is 105 degrees.

Our answer is C.
