The answer is C.
x^2 + z = 103x^2 + 22 = 103*Subtract both sides by 22*x^2 + 22 - 22 = 103 - 22x^2 = 81*square root both sides to find x*√x^2 = <span>√81</span>
<span>x = +- 9</span>

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
Let
the breadth =x
the length =6x
As we know that in a rectangle
- Length=6\times 5.1=30.6yards
- Breadth=5.1yards
Hey
Sorry if you get it wrong.
I got 28
Answer:
Step-by-step explanation: Part 1) The units rates are
A)
B)
C)
D)
Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction
Find the unit rate
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
Find the unit rate
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
Find the unit rate
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
Find the unit rate
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
The best buy is the size 48 1/4 oz
For cosФ×sinФ =0, then either cosФ or sin Ф must be zero.
cos 90 = cos 270 = 0
sin 0 = sin 180 = sin 360 = 0.
So, the values that would give you 0 are:
1. cos 90 sin Ф
2. cos 270sin Ф
3. cos Ф sin 0
4. cos Ф sin 180 and
5 cos Ф sin 360.
