Answer:
128 square feet
Step-by-step explanation:
Let the perimeter of the rectangular garden be expressed as 2(L+W)
L = length of the garden
W = width of the garden
If the length of the garden is twice its width then L = 2W; W = L/2
P = 2(L+L/2)
Since the perimeter is L + 32 (One length of a rectangular garden that lies along a patio wall and the rest of the garden is enclosed by 32 feet of fencing.)
Substituting in the formula above:
32+L = 2(L+L/2)
32+L = 2L+L
32 = 2L
L = 16 feet
Since L = 2W
W = L/2 = 16/2
Width = 8 feet
Area of the garden = Length × Width
Area of the garden = 16×8
Area of the garden = 128 square feet
Answer:
(262, 690)
Step-by-step explanation:
Given that :
Mean score = 476
Standard deviation, s = 107
2 standard deviations above and below the mean :
Mean ± 2s
Hence,
2 standard deviations below :
476 - 2(107)
476 - 214 = 262
2 standard deviations above
476 + 2(107)
476 + 214 = 690
Answer:
2 gallons left after driving 50 miles
Step-by-step explanation:
Edgar has 7 gallons of gas remaining in his car after driving for 30 miles he had 4 gallons left in the tank
Initially he has 7 gallons of gas
after 30 miles 4 gallons left
Let m be the number of miles and g be the gallons left
(0,7) (30,4)
find slope using formula 
y intercept b= 7
so equation becomes
now find out g when m= 50 miles
so 2 gallons left after driving 50 miles
Answer:
35
Step-by-step explanation:
Let number = x
(1/5 of x) + (3 * x) = 42 + (2 * x)
x/5 + 3x = 42 + 2x
1/5x + 3x - 2x = 42
1 1/5x = 42
6/5 x = 42
x = 42 ÷ 6/5
x = 42 * 5/6
x = 210 / 6
x = 35
The number is 35
Answer:
Option (1)
Step-by-step explanation:
Equation of a line passing through 
having slope 'm' is represented as,
If a line passes through (1, 4) and having slope = 3,
By substituting the values in the equation of the line,
y - 4 = 3(x- 1)
Therefore, equation of the line will be,
y - 4 = 3(x - 1)
Option (1) will be the answer.
