14 = 31.7 - 3x
-17.7 = -3x <---- I subtracted 31.7 from both sides
5.9 = x <---- I divided both sides by -3
Answer:
18 units
Step-by-step explanation:
Area of rhombus is given by 1/2(product of length of diagonals).
Given
Area of rhombus = 90 sq. units
length of one diagonal = 10 units
let the length of other diagonal be x units
Substituing the value given above in formula for area of rhombus we have
90 = 1/2(10*x)
=> 90*2 = 10x
=> 180 = 10x
=> x = 180/10 = 18
Thus, length of other diagonal is 18 units.
Answer:
The correct answer is D) 68%
Step-by-step explanation:
In order to find this, we first need to calculate out the probability of it raining and they win. We can do this by multiplying the two probabilities together,
80% * 60% = 48%
Next, we need to calculate the probability of it not raining and them winning.
50% * 40% = 20%
Now we can add the two percentages together.
48% + 20% = 68%
I honestly do not know what to say here: it's already in decimal form. Please, if you made a mistake while typing in the problem, tell me.
Substitute 3.5 for t
h(t) = -5(3.5)•(3.5) + 20
= -5•12.25 + 20
= -61.25 +20
= -41.25
If your initial equation is correct
