Answer:
<u>16</u>
Step-by-step explanation:
Dividing 2 fractions is the same as multiplying the fraction in the numerator with the inverse of the fraction in the denominator.
Therefore,
÷
×
- Note : -ve signs cancel out, cross multiply 20 and 5 to get 4, and cross multiply 12 and 3 to get 4
- ⇒ 4 x 4
- ⇒ <u>16</u>

Answer:
Option D
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Asako deposits $1000 into a bank that pays 1.5% interest compounded annually. Which inequality can she use to determine the minimum time in years 't' she needs to wait before the value of the account is 20% more than its original value?
A. 1000 . 1.01t > 1200
B. 1000 . 1.01t > 1.2
C.
D.
Formula to get the final amount by compounding is,
Final amount =
Here, r = rate of interest
n = number of compounding in a year
t = Time or duration of investments (In years)
Initial amount = $1000
Final amount = 20% more than its original value = $(1000 + 0.2×1000) = $1200
r = 1.5% = 0.015
Inequality that represents the final amount 20% more than the initial value,
> 1200
> 1.2
Therefore, Option D will be the correct option.
Answer:
Option A is correct
Step-by-step explanation:
The given equation is
h = -16t^2+6t+4
When the ball will hit the ground, height h = 0
Putting value of h = 0
0 = -16t^2+6t+4
Now solving to find the value of t
=> -16t^2+6t+4 = 0
Multiply with -1
16t^2-6t-4=0
Using quadratic formula to find value of t
a= 16, b= -6 and c= -4
Putting values,
Since time cannot be negative, so t = 0.721 or 0.72
So, Option A is correct
