1/4 = 1/8
times by 4 to find the whole song as 1/4 × 4 is 1
1 = 4/8
4/8 = <em><u>1</u></em><em><u>/</u></em><em><u>2</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>minute</u></em>
After I explain the procedure in full detail, you'll be able to generate
your own work. Here it is.
To find the greatest common factor of two numbers:
1). List all of the factors of the first number.
2). List all of the factors of the second number.
3). Scan both lists, and find factors that are on BOTH lists.
These are the COMMON factors. Write them down in a short list.
4). Scan the short list. Find the biggest number on it.
That's the Greatest Common Factor.
OK, I'll go through the first one in your picture . . . 24 and 42 :
1). Factors of 24: <em>1, 2, 3,</em> 4,<em> 6,</em> 8, 12, 24
2). Factors of 42: <em>1, 2, 3, 6,</em> 7, 14, 21, 42
3). Short list: <em>1, 2, 3, 6</em>
4). Biggest number on the short list:<em> <u>6</u> </em>
4b - 24 + 19 = 4b - (-24 + 19) = 4b - 5
The line is 180 degrees you know you have a right angle and a 64 degree angle. Add 63 and 90 (right angle) then subtract from 180
180-154= 26 degrees
First you have to know what x and y mean in the equation. They told you in the problem that x is the avg # of feet the tree grew each month. That means that the number multiplied by x is the number of months.
Y will be the total height. That number is 57.6. When y = 57.6, the number that should be multiplied by x is 16.
The tree starts at 8 ft tall, not 0 feet, so the y-intercept in this equation should be 8, because even when 0 months have passed, it will be 8 ft tall. So you know the equation will have the +8 in it added to the slope times x part.
It should be d. 16x + 8 = 57.6
