Answer:
A = 4200 ft^2
Step-by-step explanation:
We know the formula for area is
A = l*w
We need to have the same units
convert yd to ft
1 yd = 3ft
Multiply each by 70
70 yds = 210 ft
A = 210 *20
A = 4200 ft^2
Answer:constant of variation = 6/5
Step-by-step explanation:
t varies inversely as r
Let k be the constant of variation
t = k/r
t = 6 and r = 5
Substitute the value of t and r
6 = k/5
Make k the subject of the formula
k = 6/5
Answer:
Mirror across the y axis, then mirror across the x axis
Step-by-step explanation:
The answer is B 81 degrees
47: 2x * (3x^2 + x) = 6x^3 + 2x^2
48: (y^3 + 2) * 4y^2 = 4y^5 + 8y^2
