Answer:
-9a + b
Step-by-step explanation:
For this problem, let us factor out the variable a from the terms containing the variable, and apply addition and the distributive property to simplify the terms.
-5a - 4a + b
= a ( -5 + -4 ) + b
= a ( -9 ) + b
= -9a + b
Hence, the simplified expression for -5a - 4a + b is -9a + b.
Cheers.
Answer:
x = 162 cards need to be dealt with
Step-by-step explanation:
Given:
- Estimation of likelyhood of next card to be queen, a king, or an ace:
( 64 - 0.2*x ) / ( 208 - x )
Find:
For what values of x is this likelihood greater than 70%?
Solution:
- Use the likely-hood estimation relation and set up the inequality as follows:
( 64 - 0.2*x ) / ( 208 - x ) > 0.7
( 64 - 0.2*x ) > 0.7*( 208 - x )
64 - 0.2*x > 145.6 - 0.7*x
0.5*x > 81.6
x > 163.2
- It would require 162 cards to be dealt with for the probability of next card being queen, a king, or an ace is greater than 70%
We are required to find the percent of an acres is this lot
The percent of acres of the lot is 27.55%
Area of an acre = 4840 square yards
Area of the lot = Length × width
= 40 feet × 100 feet
= 4000 square feet
<em>convert feet to yards</em>
1 foot = 0.333333
4000 square feet = 1333.333 square yards
Therefore,
Area of the lot = 1333.333 square yards
percent of an acres is this lot = 1333.333 / 4840 × 100
= 0.2754820247933 × 100
= 27.548202479338
Approximately,
27.55%
Therefore,
The percent of acres of the lot is 27.55%
