Which of the statements is true a. v7 is an integer
C. V25 is a rational number
b. V16 is an irrational number
d. 190 is neither rational nor irrational number

The only valid choice is c.

Step-by-step explanation:

Rational Numbers

Rational numbers have the form a/b, where a and b are integers and b is not zero.

In other words, rationals are all numbers that can be written as a fraction.

Examples are -3/7, 11/2, 5, 0

Note the last two numbers are integers, but they are also rationals because an integer can be expressed as a fraction with a denominator of 1.

Irrational numbers are the opposite, they cannot be expressed as a fraction.

a. is not an integer since it's irrational. False

c. = 5 or -5. It is a rational number because it's an integer. True

b. = 4 or -4. It is not an irrational number because it's an integer. False

d. 190 is a rational number. False

The only valid choice is c.

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
