Answer:
Option B. 2.75
Step-by-step explanation:
It has been given in the question that a wedge has a width of 2 cm and a slope of 5.5 cm.We have to calculate the mechanical advantage of the given wedge.
We know the formula to calculate the mechanical advantage of the wedge
Mechanical advantage = Length of slope/Thickness of the widest end
= 5.5÷2 = 2.75
Therefore the answer is option B. 2.75
$88.50 you just add btw.just letting u know
Answer:
0.1469
Step-by-step explanation:
Given from the question;
Mean=8.4 hrs=μ
Standard deviation=1.8 hrs=δ
Sample size, n=40
Let x=8.7
z=(x-μ)÷(δ÷√n)
Find z(8.7)
z=(8.7-8.4)÷(1.8÷√40)
z={0.3×√40}÷1.8=1.05409
z=1.0541
Read from the standard normal probabilities table
P(z>1.0541)
=0.1459
Answer:
Step-by-step explanation:
The first rotation is clockwise, whereas the second is counterclockwise. We end up at the same point either way, and the trig functions are the same.
In summary, the final outcomes are the same, but the directions of rotation are different. For this reason: False
Answer:
h ≤ (approx) 3.7
Step-by-step explanation:
To start, we can take our knowledge that we have to spend 20$, at minimum. Therefore, we can only allocate (150-20)=130 to our payment per hour. As we pay 35$ per hour, the amount of money relative to hours would be 35*h. Therefore, as we can allocate 130 dollars or less for our hourly payments, and our money is 35*h, we can day that 35*h(the money we spend on hourly rates) ≤ 130. Then, as 35*h ≤ 130, we can divide 35 from both sides to get h ≤ 130/35, or h ≤ (approx) 3.7
