57. If you draw a diagram and make a right traveler with the Jacques, the base of the cliff, and the top of the cliff, it should be obvious that tan(35 degrees) = (cliff height)/1200m. Solving, cliff height = 1200 * tan(35 deg) = 840 meters.

Original price = 480
After 20% off, price = 480 - 0.20 * 480 = 384
After 7.5% tax, price = 384 + 0.075 * 384 = 412.80, which is the total desired.
Answer:
Step-by-step explanation:
Previous Iron content per serving=1.2 mg
Current Iron content per serving=1.8 mg
Increase in Iron content per serving=1.8-1.2=0.6 mg
Percentage of Iron Increase
Answer:
Yes
Step-by-step explanation:
If you distribute 7(x + 10), you get 7x + 70.
Answer:
total number of students = 41
Step-by-step explanation:
A different class is made up of 66% women and has 27 women in it.
Let x be the total number of students in the class
66% of students are women
66% of women are 27 women
66 % of x is 27
divide both sides by 66
x=41
So total number of students = 41
The estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders
<h3>How to determine the regression equation?</h3>
We have:
- Predictor variables = 3
- Variable 1 = Age
- Variable 2 = Mileage
- Variable 3 = Cylinders
The regression equation is estimated using:
Price = bo +b1 * Variable 1+ b2 * Variable 2 + b3 * Variable 3
Substitute the variable parameters
Price = bo +b1Age+ b2Mileage + b3Cylinders
Hence, the estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders
