Answer:
The sail is a right triangle.
Step-by-step explanation:
We are given the following in the question.
Measure of triangular sales are:
10.5 feet, 14 feet and 17.5 feet
We have to check whether it is a right angled triangle or not.
Pythagoras theorem:
According to this theorem the sum of of squares of two sides of triangle is equal to the square of hypotenuse of triangle. The hypotenuse is the longest side of the triangle.
Verifying:

Thus, the measurement of sail follows the Pythagoras theorem.
Hence, the sail is a right triangle.

Answer:
7.26
Step-by-step explanation:
If your equation is ...
y = 7.26x
the coefficient of x is the constant of proportionality. It is 7.26.
Answer:
700 lei
Step-by-step explanation:
You have a geometric sequence for which you know the common ratio and the last term.
There are only three terms, so you can solve the problem in either of two ways.
1. The brute force method
(easiest for only a few terms)
Each term is half the one before it, so each term is double the one after it.
3rd term = 100 lei
2nd term = 200
1st term = 400
Total = 700 lei
Oana spent 700 lei
2. Using formulas (best for longer sequences)
The general formula for your sequence is
aₙ = a₁rⁿ⁻¹
For your sequence,
a₃ = 100; r = 0.5
(a) Calculate a₁
Set the last term equal to the general formula.
a₃ = a₁(0.5)ⁿ⁻¹
100 = a₁(0.5)² = 0.25a₁
a₁ = 100/0.25 = 400
(b) Calculate the sum
The general formula for the sum of a geometric sequence is

Oana spent 700 lei.
Answer:
I don't know if this is what your looking for but if you had 40 ohms and 5 amps, you would get 200 volts / and 1000 watts.
Hope that helps :)
Step-by-step explanation:
there no table showing mechanic b. but mechanic a charges a one time fee of $50
35 an hour times 5 hours is 175
the total of 225 -175= $50 as a one time fee
