Sq rt of 25 is 5 and 5 is less than 10
Sq rt of 36 is 6 and 6 is less than 10
Sq rt of 9 is 3 and 3 is less than 10
<span>the train cannot exceed a length of 1100 feet
Now, train A = 28 cars at 30 feet each
Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.
</span>Now, train B = 22 cars at 40 feet each
Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.
Thus, both the <span>trains meet the requirement. </span>
Answer:
( b, 0 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = - and b = b , thus
y= - x + b ← equation of line
The line crosses the x- axis when y = 0, substitute y = 0 into equation and solve for x, that is
- x + b = 0 ( multiply through by 3 to clear the fraction )
- 5x + 3b = 0 ( subtract 3b from both sides )
- 5x = - 3b ( divide both sides by - 5 )
x = b , thus
x- intercept = ( b, 0 )
For the top part, factors are the numbers that can be multiplied together to get a certain number. So for question 5, what times what is 12? Well 1x12, 2x6, and 3x4. Those numbers are your factors. A tip is that once your lower numbers are start to match your higher, then you get no more. So like once you start saying 3x4=12 you should stop because you can’t go past 3 anymore because of 4.
Now for GCF, that stands for greatest common factor. So for question 9, what are the factors of 40 and 48? List them out then find the Greatest (largest) Common (same) factor. I hope that help!
