Answer:
x=3 meters
Step-by-step explanation:
step 1
Find the area of the rectangular pool
we have
substitute
step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have
substitute
step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so
step 4
Find the value of x if the area of the walkway equal the area of the pool
so
Solve for x
Solve the quadratic equation by graphing
The solution is x=3 meters
see the attached figure
Answer: 41/365
Step-by-step explanation:
The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).
The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.
Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.
Tan 32 = f/18
f = 18 × tan 32
= 11.25
= 11 ( to 2 sf)

D. 6
E. 2/11
To solve the system if equations substitute the given values and simplify:
4x+2y=7
y=5x
To start off we are given what h equals already so we do not have to solve for it. This means we can just plug in its values into the first equation.
4x+2(5x)=7
Solve for x
4x+10x=7
14x=7
x=7/14
x=1/2
Now that we have an x value substitute back into the second equation to find the y value and be able to create a coordinate point.
y=5x
y=5(1/2)
y=5/2
y=2.5
So your answer would be
(1/2,5/2) or (0.5,2.5)
I hope this helps!
