Answer:
p = 16
Step-by-step explanation:
Given p is directly proportional to (q + 2)² then the equation relating them is
p = k(q + 2)² ← k is the constant of proportion
To find k use the condition when q = 1, p = 1
1 = k(1 + 2)² = k × 3² = 9k ( divide both sides by 9 )
= k
p = (q + 2)² ← equation of proportion
When q = 10 , then
p = × (10 + 2)² = × 12² = × 144 = 16
Answer:
The answer is 299
Step-by-step explanation:
Even without doing the math, (and without having the requisite diagram to view), it seems likely that the rectangle was simply divided along the diagonal. And, if that's the case then the two triangles formed would have the same area. So, if one triangle's area ABC is 600 sq. yds. as the problem states, then the other triangle ACD also would be 600 sq. yds.
But if we do the math anyway, we can get the same result.
Keep in mind that:
P of rectangle = 2 ( l + w)
A of rectangle = (l x w)
A of triangle = h x b divided by 2
I'd say that the length of the rectangle is 40 and the width is 30.
P of rectangle is 2 (30 + 40) = 140 .... check
A of rectangle is 30 x 40 = 1,200 .... check
A of triangle is 30 x 40 divided by 2 = 600 ...... check

Step-by-step explanation:
V=Lhw R=$/ft³
Vv=10.5(6)(6)
Vv=378 ft³
Rv=94.5/378
Rv= 25¢ per ft³
Vs=12(8)6.75
Vs=648 ft³
Rs=162/648
Rs=25¢ per ft³
------
Vl=20(8.75)8.5
Vl=1487.5 ft³
1487.5=648n
2.295=n
