Answer:
A =90 in^2
Step-by-step explanation:
The area of the rhombus is found by
A = 1/2 d1 * d2 where d1 and d2 are the diagonal lengths
d1 = 2*6 =12
d2 = 2 *7.5=15
A = 1/2 (12*15)
A =90 in^2
Answer: The required ratio is 1:1.
Step-by-step explanation:
Let the total number of CDs be 100
of CDs is given by
According to question,
of her Jazz CDs represents of all her CDs.
Let the number of Jazz CDs be x
So, it becomes
So, Number of Jazz's CDs is 50
Number of Jazz non CDs is given by
Ratio of her CDs to her non- CDs is given by
Hence, the required ratio is 1:1.
Given that y=kx
After substituting any of the given values, we will get constant k as -0.75 or -3/4
So the answer is B. -3/4
Okay, one, how many pieces are in each package, and two, how many pieces does each person need?
3x+3y=-3
divide both sides by 3 for ease
x+y=-1
now eliminate x's
multiply that equation by 2 and add to other one
2x+2y=-2
<u>-2x+y=2 +</u>
0x+3y=0
3y=0
y=0
x+y=-1
x+0=-1
x=-1
(x,y)
(-1,0)
