Answer:32-10x
Step-by-step explanation:
Formula of direct variation is: y = kx
k is the constant of variation
y is the total value that is directly varies with the changes in x.
in this case. x is represented by a. y is represented by b.
A.) b = 0.7a ⇒DIRECT VARIATION with 0.7 as the constant of variation
B.) b = 1/8 a⁻³ ⇒ Not a direct variation. Because a has a negative exponent
C.) 5(1/a) = b ⇒ Not a direct variation
D.) 1a = b ⇒ DIRECT VARIATION with 1 as the constant of variation
Answer: Choice A) sqrt(17)
The square root of 17 is irrational because we cannot write this number as a fraction of two whole numbers (see note below). With something like choice B, we can do so and that would be 6/99; while choice C simplifies to 7 which is equivalent to 7/1. Choice D isn't fully visible, but it appears to be a fraction of two whole numbers.
Note: the denominator of the fraction cannot be 0.
First, we have to figure out how much cheese we have total. Do this by adding up all of the various cheeses.
Now to split the cheeses into sections of 1/4 pound each, we have to divide by 1/4, which is the same as multipling by 4
13 slices total
