Cost of 2 1/2 yards= $15
cost of 1 yard=?
cost of one yard= 15/(2 1/2)
=15/5/2
=15/5*2
=3*2
=$ 6
so the cost of fabric for one yard will be $6

Step-by-step explanation:
Answer:
A. -16x²+64x+8
B. 72 ft.
Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)
B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.
Answer:
Amount invested at 10% = $47,400
Amount invested at 6% = $94,800
Step-by-step explanation:
Let
Amount invested at 10% = X
Amount invested at 6% = 2X
According to given condition
Interest received at 10% + Interest received at 6% = 10428
X10% + 2X6% = 10428
0.1X + 0.12X = 10428
0.22X = 10428
X = 10428/0.22
X = 47400
So
Amount invested at 10% = X = 47,400
Amount invested at 6% = 2X = 2*47400 = 94,800
<u>Check</u>
47400*10% + 94800*6% = 10428
4740 + 5688 = 10428
10428 = 10428
Answer:
8 male, 12 female
Step-by-step explanation:
male = x
female = 2x - 4
2x - 4 + x = 20
3x - 4 = 20
3x = 24
x = 8
2(8) - 4 = 12
there are 8 male, 12 female
