So , the best way I can explain it is to try to find the closest number of lessons for both and add how much it be without going over the budget . I gave an example above
Answer:
The multiplicative inverse of y is .
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a =
Thus, the multiplicative inverse of y is .
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is .
⇒ 2 x = 1
ii. What is the multiplicative inverse of 5?
The required answer is .
Answer:
B
Step-by-step explanation:
Multiply 3.25*4+3.75= 16.75
Answer:
Part 1) The constant of variation is
part 2) The equation is
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Let
x -----> the number of square feet
y -----> the number of square yards
Three square yards are equivalent to 27 square feet
so
we have the point (27,3)
Part 1) What is the constant of variation?
The constant of variation or proportionality is equal to
substitute the values
Simplify
Part 2) What is the equation representing the direct variation?
we know that
substitute the value of k
Answer:
C.250
Step-by-step explanation:
If f(x) varies directly with x^2
f(x) = k * x^2
f(x) = 40 when x=2. Substitute these values in
40 = k(2)^2
40 = k*4
Divide by 4
40/4 = 4k/4
10 =k
f(x) = 10x^2
Now we want to find f(x) when x=5. Substituting
f(5) = 10 *5^2
f(5) = 10 *25
f(5) = 250
