<span>[4b-4]+3-b^2]+2b^3 ;b=2
= </span><span>[4(2)-4]+3-2^2]+2(2^3)
=</span> [8-4] + 3 - 4]+2(8)
= [4 + 3 - 4]+2(8)

=19
answer is <span>A. 19</span>
Diameter = Radius * 2
So radius of the circle is 25/2 = 12.5 feet
Area of a circle is:
A = πr² = 3.14 * 12.5² = 490 sq ft.
Answer:
I got this one
<n would equal 20, <m would equal 50
We have been given that Lori runs 3 miles in 30 minutes.
First of all, we will find rate at which Lori runs per minute as:
We know that 1 minute equal 60 minutes. Let us convert speed into miles per hour as:
Therefore, Lori runs 6 miles per hour.
We have been given that Alexis runs 2 kilometers in 15 minutes.
We will find rate at which Alexis runs per minute as:
1 km = 0.621371 miles.
8 km = miles.
Therefore, Alexis runs 5 miles per hour.
Since Lori' speed is greater than Alexis's, therefore, Lori ran the fastest.
Answer:
The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000
Step-by-step explanation:
Let x be the hotel charge without tax in first city
We are given that The hotel charge before tax in the second city was $1500 lower than in the first.
So, Hotel charge without tax in second city =x-1500
Tax% in first city = 10%
So, tax in first city = 0.1x
Tax% in second city =5%
So, tax in second city = 0.05(x-1500)
We are given that The total hotel tax paid for the two cities was $600.
So,0.1x+0.05(x-1500)=600
0.1x+0.05x+75=600
0.15x=600-75
x=3500
Hotel charge without tax in first city = $3500
The hotel charge before tax in the second city =x-1500=3500-1500=2000
Hence The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000
