Hank estimated width of the door to his classroom in feet. what is a reasonable estimate?

Answers

Answer 1

Answer: The measurements of an average door are 80 inches by 36 inches. In this measurement, the length is 80 inches and the width is 36 inches. If Hank estimates the width of the door of his classroom, he will then most likely estimate it at 36 inches. To convert this into feet, you must know that 12 inches make 1 foot. So, 36 inches divided by 12 inches will convert the measurement to feet: 36/12 = 3. Thus, the answer is 3 feet.

Find the amount of the principal when the simple interest rate is 4.345%, the time is 7 months, and the amount of interest earned is $274.00.

Answers

tis noteworthy that 7 months is not even a year, since there are 12 months in a year then 7 months is really 7/12 of a year.

$\bf ~~~~~~ \textit{Simple Interest Earned} \n\n I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$274\n P=\textit{original amount deposited}\n r=rate\to 4.345\%\to (4.345)/(100)\dotfill &0.04345\n t=years\dotfill &(7)/(12) \end{cases} \n\n\n 274 = P(0.04345)\left( \cfrac{7}{12} \right)\implies \cfrac{274}{(0.04345)(7)/(12)}=P\implies 10810.46\approx P$

A rectangle has a perimeter of 68 inches it’s length is 2 inches less than 3 times the width what is the area of the rectangle

Answers

Answer:

225 inches²

Step-by-step explanation:

Let the length be l and width be w

Condition 1

2l+2w=68 (Perimeter=68)--------(i)

Condition 2

l=3w-2 ---------(ii)

Putting equation (ii) in (i)

2(3w-2)+2w=68

6w-4+2w=68

8w-4=68

8w=68+4

8w=72

dividing both sides by 8

w=9 inches

now putting w=9 in (ii)

l=3(9)-2

l=27-2

l=25 inches

Now

Area of rectangle = l × w

=9 × 25

=225 inches²

Answer: Length = 25 in., width = 9 in.

Answers

Answer:

The sum of two irrational numbers is always a irrational number

Step-by-step explanation:

You can take the number π+π and the result still is an irrational number,

you can also probe with a more common number like √2 and √3, thus, we always have an irrational result.

Remember, an irrational number is the one that can not be expressed as a fraction between two integers numbers, or has an infinite number of non repetitive decimals.

Answer:

When you add two irrational numbers together, you get an irrational number. It's like if you do pi+pi and obviously you still can't write it as a fraction. Hope this helps.
