A line has one dimension which we call its length. A point has no dimensions. No length width or height. It's only a location.
9x-7= 29
9x-7+7= 29+7
9x= 36
Divide by 9 for 9x and 36
9x/9= 36/9
x= 4
Check answer by using substitution method
9x-7= 29
9(4)-7=29
36-7= 29
29= 29
Answer is x=4 (second choice)
Answer:
She bought 15 napkins
Step-by-step explanation:
First find the price before coupon
1.5 * n where n is the number of napkins
Then subtract the coupon
1.5n - 20
This is the price she paid before tax
1.5n -20 = 2.5
Solving for n
Add 20 to each side
1.5n -20+20 = 2.5+20
1.5 n= 22.50
Divide each side by 1.5
1.5n/1.5 = 22.5/1.5
n =15
She bought 15 napkins
The plane flies a distance of approximately 10.536 kilometers in <em>straight</em> line and with a bearing of approximately 035°.
A plane that travels a distance , in kilometers, with a bearing of sexagesimal degrees can be represented in standard position by means of the following expression:
(1)
We can obtain the resulting vector () by the principle of superposition:
(2)
If we know that , , , , and , then the resulting vector is:
The magnitude of the resultant is found by Pythagorean theorem:
And the bearing is determined by the following <em>inverse</em> trigonometric relationship:
(3)
If we know that and , then the magnitude and the bearing of the resultant is:
The plane flies a distance of approximately 10.536 kilometers in <em>straight</em> line and with a bearing of approximately 035°.
