Answer: The answer is 384 if your question is 12x1/2x64
Answer:
Profit
7.50
4.50
Loss
-3.50
-6.00
Step-by-step explanation:
Here, we want to write each profit as a positive number and each loss as a negative number
thus, we have that;
Profit;
7.50
4.50
Loss;
-3.50
-6.00
Answer:
B) Experiment: you imposed a treatment (new fertilizer on some plants, old on others) to determine its effect.
Step-by-step explanation:
In this situation, the fertilizer developer wants to evaluate a hypothesis, not just observe, by subjecting plants to two different treatments (new and old fertilizer) in order to determine which treatment provides a more desirable effect (more plant growth).
This process configures an experiment.
The answer is alternative B)
F= 9 x 7 = 63
G= 19 x 4 = 76
H= 12 x 4 = 48
J = 32 x 2 = 64
J is the answer
To solve this problem, let us first assign variables. Let
us say that:
A = runner
B = cyclist
d = distance
v = velocity
time = t
The time in which the cyclist overtakes the runner is the
time wherein the distance of the two is the same, that is:
dA = dB
We know that the formula for calculating distance is:
d = v t
therefore,
vA tA = vB tB
Further, we know that tA = tB + 2, therefore:
vA (tB + 2) = vB tB
4 (tB + 2) = 14 tB
4 tB + 8 = 14 tB
10 tB = 8
tB = 0.8 hours = 48 min
Therefore the cyclist overtakes the runner after 0.8
hours or 48 minutes.
