We are asked to solve for the value of "x" such that when it is added in the original area of the park it will double the area. Let us compute first the area of the original dog park (A1) and the solution is shown below:
Area = Lenght*Width = L*W where L=30 yards and W=20 yards
Area = 30*20
Area = 600 yards squared
Solving for the x, when x is added to both sides which double the area:
A1*2 = (L + 2x)*W
600*2 = (30+2x)*20
1200 / 20 = 30+2x
60 = 30 + 2x
60-30 = 2x
30/2 =x
15 = x
The value of x is 15 yards.
Answer:
39600 words
Step-by-step explanation:
Given data
In 1 minute, Alex can type 44 words
from 10:00 AM until 1 AM= 15 hours
15 hours to minutes= 15*60= 900 minutes
Hence in In 1 minute, Alex can type 44 words
in 900 minutes he will type x words
cross multiply
x= 900*44
x= 39600 words
Hence he will type 39600 words
A) 4/7
b) 1/32
c) 1 1/3 or 4/3
d) 20 1/4 or 81/4
Answer:
<h2>x = -1 and x = 4</h2>
Step-by-step explanation:
As they are traveling in opposite directions you need to do 50 + 40 to find out how far apart they travel every hour. 50 + 40 = 90. So you know that they are 90 miles apart every hour.
180 / 90 = 2. so you know that it takes them 2 hours to be 180 miles apart.
