Answer:
x = 60 cents.
Step-by-step explanation:
The man wants to make up 100 one-pound jars of nuts, it means he will need 100 pounds of nuts. He plans to use 40 pounds of one type of nuts, so he needs 60 pounds of the other type of nuts to get 100 pounds.
Now, with this we can write a linear equation:
(40*0.75)+(60*x) = 100*0.66 (1)
Where:
- 0.75 is the unit price of the 40 pounds of one type of nuts.
- x is the unit price of the 60 pounds of the other type of nuts.
- 0.66 is the unit price of 100 one-pound jars.
Let's solve the equation (1) for x:
Therefore, x = 60 cents.

A. 30% is the correct. .30 is 30%
If one foot on the model represents 70 feet on the real object, the scale is 1:70. That scale applies to all dimensions and units. In other words, you can divide any object dimension by 70 to find the corresponding model dimension in the same units.
model tail height = 392 inches / 70 = 5.6 inches
model wing span = 2537 inches / 70 ≈ 36.2 inches
model length = 2785 inches / 70 ≈ 39.8 inches
Answer:
B) 36 ft
Step-by-step explanation:
Given:
The height as a function of time is given as:
At maximum height, the instantaneous velocity becomes 0. The instantaneous velocity is the first derivative of the height function.
So, the derivative of the the given function is 0 at the maximum height.
Differentiating the above function with time, we get
Now, equating the derivative to 0 and finding time.
Therefore, time taken to reach maximum height is 1.5 s.
Now, maximum height is obtained by plugging in 
in the height equation.
Maximum height is given as:
Answer:
1/2
Step-by-step explanation:
reciprocal is an inversion of a number.
Therefore the reciprocal of 10/6 is 6/10.
Therefore, the solution would be 5/12(6/10)
Which is 1/2
