Answer:
80 racquets per hour.
Step-by-step explanation:
Divide 240 by 3, and you'll get 80. To double check, divide 400 by 5 and you'll still get 80. Hope that helps.
The answer is G. Perpendicular lines have opposite reciprocal slopes
Answer:
1732.2097 has 8 significant figures.
Step-by-step explanation:
Every non-zero digit is considered a significant number. Also, in some exceptional cases, zero can also be considered a significant figure if it is in the middle of two non-zero digits.
Just like in the number given, 1732.2097. We have 7 non-zero digits which certainly would be considered to be significant figures. Zero is between two significant figures, 2 and 9, therefore, it would also be referred to as a significant figure.
Therefore, the number, 1732.2097, has 8 significant figures.
So, first of all you have to identify the two equations which are: y=7x-8 and y=5x-2. after identifying the two equation you can choose one of them to start with. I chose the first one and I'll use substitution method, which means I'll pug in numbers in the unknown variables to find the value of x. Y=7x-8, I'll substitute the value of y in the equation that I chose and plug in the value of the second equation. Y=7x-8 --> 5x-2=7x-8 (this is our new equation). After that I'll combine like terms. -2+8=7x-5x --> 6=2x --> 6/2=x --> 3=x. So x=3 and that's the answer using substitution method. If the two points are graphed, they will intersect at the point (3,13). To see where the intersection of the line we can use a calculator to make it faster. So we plug in the points of the two lines in the calculator we graph and find the intersection point.
Answer:
Using the slope-intercept form, the slope is 2 .
