y^x:y^x = 1 because a:a=1 for every a
but y^x:y^x=y^(x-x)=y^0
Ex: 2^3:2^2=2^(3-2)=2
8:4=2
⇒ y^0=1
Answer:
$5.75
Step-by-step explanation:
20=9.75 + 4.5 + c
20-9.75-4.5=c
5.75=c
A/8 +1= 4 because a is devided by 8 then you have to add one to equal 4
Answer:
Step-by-step explanation:
B ----> Base Area
Base is triangle
base = b = 10 in
height = h = 6 in
Area of base B = 

B = 30 in²
H = 15 in
Volume of triangular prism = BH
= 30 * 15
= 450 in³
Find the unit costs and compare them:
$1.99
---------- = $0.199/oz
10 oz
$2.99
-------------- = $0.17/oz
18 oz
Clearly, the 18 oz bag for $2.99 is the better buy, at $0.17/oz versus $0.199 oz for the 10 oz bag for $1.99.
