Step-by-step explanation:
3)
2x + 3y = 12
Solve for y. Then you have y = mx + b, and m is the slope.
3y = -2x + 12
y = -2/3 x + 12
slope = -2/3
6x - 4y = 8
-4y = -6x + 8
y = -6/(-4) x + 8/(-4)
y = 3/2 x - 2
slope = 3/2
Since the slopes -2/3 and 3/2 are opposite reciprocals, the lines are perpendicular.
4)
3x - 4y = 12
-4y = -3x + 12
y = -3/(-4) x + 12/(-4)
y = 3/4 x - 3
slope = 3/4
4x + 3y = 15
3y = -4x + 15
y = -4/3 x + 5
slope = -4/3
Since the slopes 3/4 and -4/3 are opposite reciprocals, the lines are perpendicular.
Answer:
The new volume will be V + 0.06V or 1.06V
Step-by-step explanation:
The volume of the sphere increased by 6% or 0.06V. This means the total volume of the sphere will be V + 0.06V or 1.06V.
<span>Mrs. Kennedy is buying 315 pencils
But pencils are sold in boxes of 10
How can she use rounding in this given situation
315 = number of pencil she wants to buy
10 = number of pencils per box
=> 315 / 10
=> 31.5, Since she needs 315 pencils, she need to buy 31 boxes and half.
However, they are not selling half box. So Mrs. Kennedy needs to round off the
number of pencils to buy to its nearest value.
Since the value next to the decimal points is 5, Mrs. Kennedy will round up.
Therefore, Mrs. Kennedy will now buy 32 boxes of pencils or equals to 320
pencils.</span>
