Answer:
"Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce."
In order to find the rounded cost per one item (in this case, per one ounce) Susan needs to divide the total price between the number of units and after that, round the result obtained up to the nearest cent.
Therefore:
Brand A
2.55$/12 ounces= 0.2125 $/ounce
As the third decimal digit, 2, is closer to 0 than to 9, then we maintain the second decimal digit as 1.
The price per unit of brand A after rounding it up is 0.21 $ per ounce
Brand B
1.45$/8 ounces= 0.1812
As the third decimal digit, 1, is closer to 0 than to 9, then we maintain the second decimal digit as 8.
The price per unit of brand B after rounding it up is 0.18 $ per ounce
( 7 x 4 ) ^4 = 7^4 x 3^4
The rule is:
( a * b )^n = a^n * b^n
Answer:
D ) Power of a Product Property
Answer:
49π and 153.86 when multiplyed by 3.14.
Step-by-step explanation:
Hi!
The formula for finding the area of a circle is πr².
In that case, all we have to do is substitute 7 inches for our r.
7² × π
= 49π
If you want that solved out, we can substitute a rational number for π (3.14)
49 × 3.14 = 153.86
Thus, the area of the circle is 
, 153.86 roughly.
Hope this helps!
∈ ≤ ≥
-6 ≤ 2x + 6 ≤ 6 ( seperate the two inequalities)
2x + 6 ≥ - 6
2x + 6 ≤ 6 (solve the inequalities)
x ≥ -6
x ≤ 0 (find the intersection)
solution is : x ∈ { -6, 0 }
First find the amount at the end of the deferment period using the formula of the future value of a compound interest
A=8,960×(1+0.2735÷12)^(6)
A=10,257.25
Use the amount we found as the present value to find the monthly payment by using the formula of the present value of an annuity ordinary to get
PMT=10,257.25÷((1−(1+0.2735
÷12)^(−12×6))÷(0.2735÷12))
=291.27 ....Answer
