Answer:
2 seconds
Step-by-step explanation:
At max height, velocity = 0
u = 64 feet/sec
v = 0
a = -32
t = ?
v = u + at
0 = 64 - 32t
32t = 64
t = 2
Answer:
The solution is (-2, 0)
Step-by-step explanation:
Re-write -2x=-y+4 x=-2 in column form:
x=-2
-2x=-y+4
Next, substitute -2 for x in the second equation:
-2(-2) = -y + 4, or:
4 = -y + 4. Thus, y must be 0.
The solution is (-2, 0)
Answer:
Find out the what is the price of oranges this week .
To prove
As given
last week the price of oranges at the farmers market was $1.75 per pound.
This week a price has decreased by 20% .
20% is written in the decimal form

= 0.20
Decreased in the price = 0.20 × 1.75
= $0.35
The price of oranges this week = Price of orange at last week - Decreased in the price
= $1.75 - $0.35
= $ 1.4
Therefore the price of oranges this week is $1.4 .
Answer:
25 shelves
Step-by-step explanation:
The number of shelves he can make is basically the total amount of wood he has divided by the amount of wood it takes per shelf.
Given in the problem:
Total Amount of Wood = 15 meters
Wood Amount needed per Shelf = 3/5
Hence,
Number of Shelves = 15 divided by 3/5
Note: dividing by a fraction means multiplying by its reciprocal (upside down version)
We show the division below:
Number of Shelves = 
So Tom can make 25 shelves
Answer:
value of x = 20°
Step-by-step explanation:
the given pair of angles are pair of co - interior angles
So, their sum = 180°
=》3x - 10° + 5x + 30° = 180°
=》8x + 20° = 180°
=》8x = 180° - 20°
=》8x = 160°
=》x = 20°
