So the expression for total number of straws is: 15p+48b
Step-by-step explanation:
We know that:
Straws in a pack = 15
Straws in a box = 48
Here
p denotes the number of packs and b is the number of boxes.
The product of number of packs and number of straws in a pack will give us the total straws in packs
15*p = 15p
Similarly, the product of number of boxes and number of straws in a box will give us the total straws in box
48*b = 48b
The sum of both will give us the total number of straws
So the expression for total number of straws is: 15p+48b

Answer:
y =

y =
- 8
y = 
Step-by-step explanation:
To know the pairs that are perpendicular lines, we need to understand what makes a line perpendicular to another.
Perpendicular lines generally have slopes;
m and
So, any of the pairs with a negative inverse value of slope will be perpendicular.
y =
- 8 slope = 
y =
slope = 
We see they are negative inverses
y =
- 8 slope = 
y =
slope = 
These are also negative inverses.
So you know that 11 U.S. Dollars can be exchanged for 10 Euros which is 10/11. To figure out how many Euros you will receive for 1 Dollor you have to find the unit rate. To do this divide 10 by 11. The answer is 0.90

Answer:
Step-by-step explanation:
Nothing in the problem statement tells you anything about the directions of lines LK or QT, so you cannot conclude they are parallel. You only know that EV crosses CN and KT at right angles.
EJ ⊥ CN means m∠CJV = 90°, as all angles at the intersection of EJ and CN are 90°.
