A half times a half is a quarter. You can think of it this way: 1/2 is equivalent to 0.5, so you do 0.5 times 0.5 which is 0.25.(answer)
The area of Neil's rooms total
... (10 ft)×(10 ft) + (14 ft)×(14 ft) = 100 ft² +196 ft²
... = 296 ft²
Since Neil will save $1 per square foot by waiting on the sale, he will save
... (296 ft²)×($1/ft²) = $296
Let the number of nickels be = x
Let the number of dimes be = d
Let the number of quarter be = n
Given is, she has twice as many dimes as quarters
d=2n or n = 0.5d
She has two less quarters than nickles.
n= x-2 or
x= n+2
Total values of coins is = $2.60

Now replace x with (n+2) and d with 2n





Now x=n+2 ; x=5+2 = 7
d=2n ; d=2(5) = 10
Hence, Elina has 7 nickels, 10 dimes and 5 quarters.
Answer:
b₂ = 5
Step-by-step explanation:
Substitute the given values into the formula
16 =
× 4 × (3 + b₂)
16 = 2(3 + b₂) ( divide both sides by 2 )
8 = 3 + b₂ ( subtract 3 from both sides )
5 = b₂
