Answer:
120 cm^2
Step-by-step explanation:
area of a rhombus is pq/2
that means that the product of the two diagonals divided by 2 is the area of the rhombus.
so that means one diagonal is 24 and one is 10, (we are given what half of both diagonals are so just multiply by 2)
now put it in the formula
24x10 = 240
now divide by 2
240/2 = 120

Answer: B). 38:inches
Step-by-step explanation: the two length 20 and 28 have a close range of value. So the next close range of value is the 38 inch which will make a perfect fit.
Note this rule is by trial and error method and no formula is behind it.
46 divided by 4 is 11.5, R = 11.5
Answer:
2.5e-0.04x = 1.2 + 0.2x
Step-by-step explanation:
Given that:
Insect A:
Initial population, Po = 2.5 million
Rate of decline = 4%
Insect B:
Initial Population (Po) = 1.2 million
Yearly increase = 200,000 = (200,000/1,000,000) = 0.2
For insect A:
P(t) = Po(1 - r)^t = Po*e^-rt
Po*e^-rt = 2.5e^-0.04t ----(1)
For Insect B:
P(t) = Po + (yearly increase) * t
P(t) = 1.2 + 0.2t - - - - - (2)
Equating (1) and (2)
2.5e^-0.04t = 1.2 + 0.2t
Answer:
50 boxes
Step-by-step explanation:
first we can find how many apples there are
42*12=504
then subtract 4 of the rotten apples
504-4=500
then find how many boxes there can be
500/10=50
