Answer:
20
Step-by-step explanation:
if 7 nails are required for each piece of wood, you must determine how much wood you have in total by dividing the amount of nails by 7.
If you have used 40 nails out of sixty, you 20 left because
60-40=20
Answer:
ok let me slide
Step-by-step explanation:
Distance=√(x2−x1)2+(y2−y1)2 Distance = x 2 - x 1 2 + y 2 - y 1 2. Substitute the actual values of the points into the distance formula. √((8)−(3))2+((−7)−(−5))2 8 - 3 2 + - 7 - - 5 2. Simplify.
Unsure of what you mean by "reference number."
I do recognize that 11pi/9 is in quadrant III. I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.
That difference is 2pi/9.
5x + 55 <= 92.5
5x <= 92.5-55
5x <= 37.5 /: 5
x <= 7.5
