Step-by-step explanation:

because 35 divided by 5 is 7 and 15 divided by 15 is 3 making 7:3

hope it helps

Answer:

Option: C is the correct answer.

c) both the square root of 0.25 and -the square root of 16 are rational.

Step-by-step explanation:

Rational Number--

A number which could be expressed in the form of p/q where p belongs to integers and q belongs to natural numbers.

and if it could not be expressed as one then the number is called a irrational number.

(1)

\sqrt{0.25}

Now, we can represent it as follows:

$√(0.25)=\sqrt{(25)/(100)}\n\ni.e.\n\n√(0.25)=\sqrt{((\pm 5)/(10))^2}\n\ni.e.\n\n√(0.25)=\pm (5)/(10)=\pm (1)/(2)$

Hence, the number could be expressed in the form of p/q

Hence, the number is a rational number.

$-√(16)$

It could be represented as follows:

$-√(16)=-√((\pm 4)^2)\n\ni.e.\n\n-√(16)=\pm 4$

Hence, the number is a rational number.

The answer is C because the only time a square root is irrational is if it is a negative like -16 it is irrational because you can’t have 4^2=4*-4

A boy leaves on a bicycle trip at the rate of 8 mph. One hour later the father, realizing that his son forgot his camping gear, sets out by car. How fast must the father drive to overtake the boy in 15 minutes?

Answers

Speed of father is 40 mph

Given that;

Speed of boy on bicycle = 8 mph

Total time taken by father = 15 min = 0.25 hour

Find:

Speed of father

Computation:

Distance = Speed × Time

So,

Boy's cover distance = Father's cover distance

[(Speed of boy on bicycle)(Time taken by boy)] = [(Speed of father)(Time taken by father)]

[(8)(1 + 0.25)] = [(Speed of father)(0.25)]

[(8)(1.25)] = [(Speed of father)(0.25)]

Speed of father = 10 / 0.25

Speed of father = 40 mph

1st equation to find out how far boy will have traveled in 1hr 15 minutes:

8/1=x/1.25 (8 miles over 1 hour = x miles over 1.25 hours)
8(1.25) = 1(x)
10 = x

Now, divide 10 by .25 (15 minutes aka 1/4 hour) to get the speed father will have to drive.

10/.25 = x/1

x = 40 MPH
