Answer: 22 1/2
Step-by-step explanation: The scientist starts off his experiment with only <u>100</u> bacteria cells okay. It takes <u>15</u> hours for the bacteria cells to double there population. Meaning <u>15 hours</u>=<u>200</u> bacteria cells. So what you have to do know is find out what to do next which is count <u>15</u> in <u>half.</u> After that step you should get <u>7 1/2.</u> know what you do is add <u>15+7 1/2= 22 1/2.</u> meaning <u>22 1/2</u> is your answer.
Divide $31.75 by 2 to find out the cost for 1 pack. Then multiply that total times 3 to get the total for 3 packs.
31.75/2 = 15.875
15.875 x 3 = 47.625, rounded to $47.63
Answer:
Step-by-step explanation:
The marks on both sides of the triangle shows that the sides are equal. This means that the triangle is an isosceles triangle.
This means that
x = 4
Also, in an isosceles triangle, the base angles are equal. Therefore, the sum of the base angles would be 2y.
The sum of angles in a triangle is 180 degrees. Therefore,
2y + 50 = 180
Subtracting 50 from both sides of the equation, it becomes
2y + 50 - 50 = 180 - 50 = 130
2y = 130
y = 130/2 = 65 degrees.
Here's a graph. Remember that the y intercept crosses the y axis.
Answer:
6
Step-by-step explanation:
4/5=80%
1/8=12.5%
80÷12.5=6.4
