Write each mixed number as a decimal

Mathematics

Hey there! I'm happy to help!

If we want to turn this into a decimal, we only need to find what the fraction is as a decimal because we already know the whole number

QUESTION 1

We know that our decimal is 4 point something. We know that this something is 1/5. To turn a fraction into a decimal, you just divide the numerator by the denominator.

1÷5=0.2

We add the whole number and fraction.

4+0.2=4.2.

QUESTION 2

14÷15=0.933333 repeating

We add this to the whole number.

12.93333333 repeating.

QUESTION 3

5÷32=0.15625

We add this to the whole number.

5.15625

Have a wonderful day! :D

MZJ and m M are base angles of isosceles trapezoid JKLM. If mZJ = 18x + 8 and m_M=11x + 15 find m2K.
maxonik [38]

The question is incomplete. Here is the complete question.

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°

A car's velocity changes at a rate of 36 miles per hour in 0.5 hour.
kotegsom [21]

Answer:

72

Step-by-step explanation:

In order to find the acceleration we need first to defined it, so:

acceleration=((final velocity)-(initial velocity))/time interval

a=(vf-vi)/dt

But (vf-vi) actually represents the velocity change, so (vf-vi)/dt represents the velocity change rate. This means that in our case:

a=(36miles/hour)/(0.5hours)

a=72miles/hour^2

In conclusion the acceleration is a=72miles/hour^2, without units just 72.

\bf \textit{Pythagorean Identities} \\\\ sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{csc(\theta )-sin(\theta )}{cos(\theta )}\implies \cfrac{~~\frac{1}{sin(\theta )}-sin(\theta )~~}{cos(\theta )}\implies \cfrac{~~\frac{1-sin^2(\theta )}{sin(\theta )}~~}{cos(\theta )}
