Answer:
try 87 or 86
Step-by-step explanation:
Answer:
width is 27 yards and length is 123 yards
Step-by-step explanation:
Perimeter of a rectangle is 2(L + W).
If length is 96 more than width, then we know L = 96 + W
Since we also know the perimeter, we can put them into an equation and solve for the length and width:
2(L + W) = P
2(96 + W + W) = 300
96 + 2W = 150
2W = 54
W = 27
Plug this back into L = 96 + W to find the length:
L = 96 + W
L = 96 + 27
L = 123
Therefore, the width is 27 yards and length is 123 yards.
Answer: (a) y = 250(1.8)ˣ (b) 89,262 bacteria
<u>Step-by-step explanation:</u>
Use the exponential growth formula y = a(b)ˣ where
- a = Initial Value
- b = 1 + r (for growth) or 1 - r for decay
- r = rate (convert percent to a decimal)
a) Given: a = 250, r = 80% (.80) → b = 1.8
y = 250(1.8)ˣ
b) Given: x = 10
y = 250(1.8)¹⁰
y = 89,261.68 = 89,262 (rounded to the nearest whole number)
Answer:
The line '10x-8=10' should be '10x-8=4x+10'
He took 2x away on the right side , as opposed to adding it.
