Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
The prime number will be 69 and 89
Answer:
9^2= (x+2)^2+(y+8)^2
Step-by-step explanation:
The equation is r^2=(x+h)^2+(y-k)^2
A- it’s a Pythagorean triple(6, 8, 10)
Answer:
y = -1/5x + 19/5 or
x + 5y = 19.
Step-by-step explanation:
The slope of the line (m) = (5-3) / (-6-4)
= -1/5.
Using the point-slope form of the equation of a line:
y - y1 = m(x - x1) m = -1/5. x1 = 4 and y1 = 3 , so:
y - 3 = -1/5(x - 4)
y - 3 = -1/5x + 4/5
y = -1/5x + 19/5 which is the equation in slope-intercept form.
Converting to standard form ( multiplying by 5):
5y = -x + 19
x + 5y = 19.
