HELPPPPPPPPP i have the most trouble with math what’s the answer??
kiruha [24]

Answer:

option B

3

Step-by-step explanation:

Given in the question an expression

\sqrt\frac{48}{x}

Whole numbers are positive numbers, including zero, without any decimal or fractional parts.

Possible range of domain will be 1 ≤ x ≤ 48

We know that perfect square between 1 and 48 are

1 , 4 , 16 , 25 , 36

1)

x = 3

√48/3 = √16 = 4

2)

x = 12

√48/12 = √4 = 2

3)

x = 48

√48/48 = √1 = 1

A high school football game Jill buys 6 hot dogs and 4 soft drinks for
ryzh [129]

Answer: D


Step-by-step explanation:Lets label hot dogs as 'h' and soft drinks as 's'


6h + 4s = 13 (Equation 1)

3h + 4s = 8.50 (Equation 2)


We can solve by process of elimination.


Subtract equation 1 from equation 2.


We get:


3h = 4.5

h = 1.5


So that means that the hot dog costs $1.50 which is answer choice D.
