Answer:
59 yards x 99 yards
Step-by-step explanation:
Soccer fields are rectangular. If the width is W and the length is L:
316 = 2W + 2L
5841 = WL
We have two equations and two variables. Start by solving for one of the variables in the first equation:
316 = 2W + 2L
158 = W + L
W = 158 − L
Substitute into the second equation
5841 = (158 − L) L
5841 = 158 L − L²
L² − 158 L + 5841 = 0
Factor (or use quadratic formula):
(L − 59) (L − 99) = 0
L = 59 or 99
Find W:
W = 99 or 59
Therefore, the dimensions of the soccer field are 59 yards by 99 yards.
Answer:
£105.00
Step-by-step explanation:
£7/hour
Time and a quarter: (£7/hour)*(1 + 1/4) = (£8.75/hour)
Time and three quarters: (£7/hour)*(1+ 3/4) = (£12.25/hour)
Saturday for 5 hours: (£8.75/hour)*(5 hours) = £43.75
Sunday for 5 hours: (£12.25/hour)*(5 hours) = £61.25
Sum of £43.75 + £61.25 = £105.00
Answer:39
Step-by-step explanation:
90-51=39
F(x)=x/2-x and g(x)=2x^3-x/2-x so
f(x)-g(x)=x/2-x-2x^3+x/2+x
f(x)-g(x)=-2x^3+2x/2
f(x)-g(x)=-2x^3+x or if you prefer:
f(x)-g(x)=x(-2x^2+1)
Given:
Jennifer and Jane are best friends. They placed a map of their town on a coordinate grid and found the point at which each of their house lies. If Jennifer's house lies at (2, 12) and Jane's house is at (16, 2) and they wanted to meet in the middle.
