D is the answer.

It is rational because it can be expressed as a ratio of 2 integers. All rational numbers are real. It is not an integer because it is not a whole number or the ngative of one. It is a fraction.

<h2>Answer:</h2>

Option: D is the correct answer.

          D.   5/7

<h2>Step-by-step explanation:</h2>

We know that a real number is a combination of:

  1) Rational numbers

 2) Irrational numbers

Also, further the rational number is divided into integers and non-integers.

If a number is represented as a whole i.e.  .... -3, -2,-1,0,1,2,3,.....

Then such numbers are integers and any number of the form p/q where q≠1 and q does not properly divide p are non-integers but a rational number.

Hence, among following given options the number which is rational and a real number but non-integer is:

          Option: D

( Option: B is an integer

and option: C is an irrational number)

A car with 15 gallons of gasoline drives 420 miles until the tank is empty. Write a linear equation that describes the amount of
storchak [24]

Answer:

y = -\dfrac{1}{28}x + 15

Step-by-step explanation:

The car uses 15 gallons of gasoline to drive 420 miles.

(15 gal)/(420 mi) = 1/28 gal/mi

The car uses 1/28 gallon of gasoline per mile.

y = mx + b

When x = 0, at the start of the drive, the car has 15 gallons of gasoline.

y = mx + 15

Then for every mile it travels, the amount  of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

y = -\dfrac{1}{28}x + 15

Given: mHL =40°, mEV =130°, mVL =110°. Find: m∠EYH.
IgorC [24]

Answer:

<h2>The measure of angle EYH is 25°.</h2>

Step-by-step explanation:

Notice that ray EY is a tangent and ray VY is a secant.

In this case, we use the theorem that states <em>"the angle formed by a tangent and a secant is half of the difference of the intercepted arcs".</em>

In this case, the intercepted arcs are EH  and EV. We know that a whole arc is 360°, so

arc(EH)=360-40-110-130=80

Using the theorem, we have

m\angle EYH=\frac{1}{2}(arc(EV)-arc(EH))=\frac{1}{2}(130-80)=\frac{1}{2}(50)\\   m \angle EYH = 25\°

Therefore, the measure of angle EYH is 25°.

Michelle made 26 more sales calls last month than Allen. Together, they made 120 calls. How many calls were made by Michelle?
arlik [135]

Answer:


Step-by-step explanation: OK so Allena and micheal has 120 all together right

and micheal made 26 more right

So they had the same number but its changed when micheal made 26 more calls

so 120-26=73

so they both cant have 73

So we would divided 73 by 2

since its 2 of them

So its M=47 and A=47

than add the 26 calls to Michael

and it would be 73

and than you add 47 (when they say add them all together)

from allen

and get 120

so the answer is 73 calls by micheal.
