Answer:
Kimberly scores 8.77 points per event
Step-by-step explanation:
Total scores in four gymnastic events = 35.08 points
Total events = 4
If she scored the same amount in each event,how many points did she score each?
Kimberly points per event = Total scores in four gymnastic events /
Total events
= 35.08 points / 4 event
= 8.77 points per event
Kimberly scores 8.77 points per event
Perimeter (p) = 2×length (l) + 2×width (w)
p = 2l+2w
area (a) = l×w, so solve for one (I'll use l):
since p = 30, and a = 50, substitute the "a÷w" in for l in the perimeter equation:
Now plug in p and a values:
therefore width can be either 5 or 10 (but not both), so let's plug in:
l = a÷w = 50÷5 = 10
So if w = 5, then l = 10
D) 5 feet, and 10 feet
<span>Neighbor: 2/5(x) </span>
<span>Remainder = x - 2/5(x) = 3/5(x) </span>
<span>Cousin = 4/9 * 3/5(x) = 4/15(x) </span>
<span>x - 2/5(x) - 4/15(x) = 15 </span>
<span>x - 6/15(x) - 4/15(x) = 15 </span>
<span>x - 10/15(x) = 15 </span>
<span>(15x - 10x) = 225 </span>
<span>5x = 225 </span>
<span>x = 225/5 = 45 </span>
<span>Therefore, he made 45 rolls</span>
2.3^2= 2.3*2.3
2.3^2=5.29
4^3=4*4*4
4^3=64
64+13-2*4=300
Answer:
25
Step-by-step explanation:
i think you mean +10x
but (x+a)^2 = x^2 + 2ax + a^2
2ax = 10x
ax = 5x
a = 5
so (x+5)^2 = x^2+10x+25
