Answer:
t < 6
Step-by-step explanation:
Given
- 48 < - 8t
Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.
6 > t , that is
t < 6
Let x be the total number of papers that need to be delivered.
Number of papers Candy can deliver in 1 minute =x/85
Number of papers Tim can deliver in 1 minute =x/65
Time taken for both Tim and Candy all the papers together =x/ (x/85 +x/65)
= x/ (150x/ 5525)
=221/ 6 minutes
=36 minutes 50 seconds
It takes Tim and Candy 36 Minutes and 50 Seconds to deliver all the papers when they work together.
I hope this helps \(^_^)/

Answer:
0
Step-by-step explanation:
Use the discriminant formula for parabola
Since the answer is negative, we will have 2 imaginary roots so we won't have any real roots
the answer is Y/g
y=fgx
y/g=fx,which mines f(x)=y/g
Answer:
Step-by-step explanation:
Example:
If E, F, G and H are respectively the mid-points of the sides of a parallelogram ABCD shows that ar ( EFGH) = 1/2 ar ( ABCD)
If E, F, G and H are respectively the mid-points of the sides of a parallelogram ABCD show that ar (EFGH) = 1/2 ar (ABCD)
Given: A parallelogram ABCD where E, F, G, H are the mid-points of AB,BC,CD & AD respectively
To prove: ar (EFGH) = 1/2 ar (ABCD)
Proof: Join H & F
Now,
So, AD || BC ( Opposite sides of parallelogram are parallel)
> DH || CF ( Parts of parallel lines are parallel)
Also, AD = BC ( Opposite sides of parallelogram are equal)
1/2AD = 1/2 BC
DH = CF
( H is mid-point of AD
F is mid-point of BC)
