Answer:
x ≈ 2.91644500708
Step-by-step explanation:
The equation can be simplified to ...
2(4^x) +4(4^x) = 342
6(4^x) = 342
4^x = 57
Taking logarithms, we get ...
x = log₄(57) = log(57)/log(4)
x ≈ 2.91644500708
Answer:
To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Step-by-step explanation:
If Trina has 3 and Randall gave her a fourth multiply 3 by 4: Randall had 12. If Randall had 12 and Selena gave him a third multiply 12 by 3: Selena had 36. If Selena had 36 and Anna gave her half multiply 36 by 2: Anna had 72. Anna had 72 brownies at the beginning :)
Answer:
17
Step-by-step explanation:
c = 12 (Replace c in equation with 12):
12 + 5
= 17
Answer:
The simple interest earned in one year is $10.5
Step-by-step explanation:
Simple interest = p × r × t
Where,
p = principal
r = interest rate
t = time
Principal= $350
Interest rate = 3%
=3/100
=0.03
Time= 1 year
Simple interest = p × r × t
= $350 × 0.03 × 1
= $10.5
The simple interest earned in one year is $10.5
