Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.
Answer:
The measure of the angles are 72 degrees and 18 degrees
Step-by-step explanation:
we know that
If two angles are complementary, then their sum is equal to 90 degrees
Let
x -----> the measure of an angle
y-----> the measure of he other angle
we know that
x+y=90 -----> y=90-x -----> equation A
x=y+54 ----> equation B
substitute equation B in equation A and solve for y
y=90-(y+54)
y=90-y-54
2y=36
y=18°
Find the value of x
x=y+54 -----> x=18+54=72°
therefore
The measure of the angles are 72 degrees and 18 degrees

Answer:
436.96
Step-by-step explanation:
Using the compoybd interest formula A=P(1+R÷N)^nt
A= Final amount 436.96
P= Initial Balance 420
r= interest rate 4%
n= number of times interest applied per time period 2
t = number of times periods elapsed 2
Answer
n = 30
Explanation
To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.
You 'remove' these numbers in backward PEMDAS.
So to 'remove' the 18, you subtract both sides by 18.
3-18 = -15
-n/2+18-18 = -n/2
So now you are left with -15 = -n/2.
To 'get rid' of the 2, you multiply each side by 2.
-15×2 = -30
-n/2×2 = -n
And now you have -30 = -n.
To 'get rid' of the negative sign, you multiply both sides by -1.
-30×-1 = 30
-n×-1 = n
So you get 30 = n or n = 30.
