Answer:
He will need 15.6 feet of fence
Step-by-step explanation:
Jim's back yard has the following dimensions;
Length=120 feet
Width=75 feet
The gardens dimensions can be calculated using the expression;
Length of garden=Length of back yard/scale factor
where;
Length of back yard=120 feet
Scale factor=25
replacing;
Length of garden=120/25
Length of garden=4.8 feet
Width of garden=Width of back yard/scale factor
where;
Width of back yard=75 feet
Scale factor=25
replacing;
Width of garden=75/25
Width of garden=3 feet
The gardens dimension are;
Garden width=3 feet
Garden length=4.8 feet
To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;
Perimeter=2(length+width)
Perimeter=2(4.8+3)=15.6 feet
He will need 15.6 feet of fence
When there are more the one values on right side for any value on left side , then it is not a function .
In the given figure as all the values on left side have single and unique answers on the right side ,
So yes V(x) is function.
TRUE
Multiply this 15 mph by the conversion factor derived from 1.6 km = 1 mi:
15 mph 1.6 km
------------ * ---------- = 24 km/hr
1 1 mi
The cyclist's speed in km/hr is 24 km/hr.
In 3 hrs the cyclist can cover (24 km/hr)(3 hr) = 72 km.
18 1/2 -17 3/4
= 18.50 -17.75
= 0.75
= 3/4
The 4th selection is appropriate.
It takes 8 trees to make a stack 1.2 metres tall, so if ut takes 20 minutes per tree, then it will take 8 × 20 or 160 minutes, or 2 hours 40 minutes.
