From the first 2 statements again , x + 8 = y.
area of the hole would be 4x cm^2
area of sheet without hole is 9y cm^2
9y - 4x =76 ------------- eqn one
y = x + 8 ----------------eqn two
subs eqn two into one and u got it
btw what questions are these :o
David drove at about 59 mph!
Answer:
$2.77 per quart.
Step-by-step explanation:
There are four quarts in a gallon.
4 * 3 = 12
There are 12 quarts in 3 gallons.
The price per quart should be $2.77.
Hope this helps.
Option B:
A ray has two endpoints and extends infinitely in both directions.
Solution:
Option A: Two lines that intersect are called skew lines.
It is false because,
Two lines are said to be skew lines if they do not intersect and do not lie in the same plane.
Option B: A ray has two endpoints and extends infinitely in both directions.
It is false because,
A ray has one endpoint and extends infinitely in one direction.
Option C: A line is a set of points that extends infinitely in both directions.
It is false true.
A line is a set of points that extends infinitely in both directions.
Option D: Two lines in the same plane are said to be perpendicular if they never intersect.
It is false because,
Two lines are said to be perpendicular if they are intersect.
Hence Option B is true. A line is a set of points that extends infinitely in both directions.
Isn’t it a 90 degree angle
