Answer:

A, C, F.

Step-by-step explanation:

A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.

So, expression A has a square root of x, that is a rational exponent.

Expression C has variables in the denominators, that is negative exponent.

Expression F has variable at the exponent.

Answer:

A, C and F.

Step-by-step explanation:

A is not a polynomial because it contains a square root.

C is not a polynomial because it contains division by a variable (7/2x).

F is not one also because the variable is in the exponent (5^4x).

The Schuller family has five members. Dad is 6ft 2in tall. Mom is 3 inches shorter than Dad, but 2 inches taller than Ivan. Marc

Answer:

Mean = 5 feet 2 inches.

Step-by-step explanation:

1 feet = 12 inches

Height of Dad = 6 feet 2 inches = {(6 × 12)+2} = 74 inches

Mom is 3 inches shorter than dad = 74 - 3 = 71 inches (5 ft 11 in)

Since mom is 2 inches taller than Ivan,

Height of Ivan = 71 - 2 = 69 inches (5 ft 9 in)

Marica is 5 inches shorter than Ivan,

Height of Marica = 69 - 5 = 64 inches (5 ft 4 in)

Marica is twice as tall as Sally-Jo.

Height of Sally-Jo = 64 ÷ 2 = 32 inches (2 ft 8 in)

Hence the mean height of the Schuller family

= $\frac{74+71+69+64+32}{5}$

= 62 inches

converting 62 inches to feet = $\frac{62}{12}$ = 5 feet 2 inches

Mean height of the Schuller family is 5 feet 2 inches.

25 percent is the same as the decimal 0.25.

Multiply 100 by 0.25 to see what 25% of 100 is.
100x0.25=25

Then, to find the price raised by 25%, add 25 to 100.
100+25=125

The final answer is $125.

Hope this helps!
