The answer is 90

Step-by-step explanation:

So there is 12 inches in 1 foot so multiply 12 by 7 and that is 84 plus six because it said 7 1/2 feet 1/2 of a foot is 6 inches so right way to put the problem is...

12 x 7= 84+6=90 Hope this helps!

Which set of numbers is correctly ordered from greatest to least?

shepuryov [24]

Answer:

Step-by-step explanation:

Here is the corrected question and options:

Option 1:

$7\frac{1}{3} , \frac{221}{30} , 7.36, 3.16\sqrt{2e}$

Option 2:

$7\frac{1}{3} , 7.36 , \frac{221}{30} , 3.16\sqrt{2e}$

Option 3:

$3.16\sqrt{2e}, 7.36 , \frac{221}{30} , 7\frac{1}{3}$

Option 4:

$3.16\sqrt{2e}, \frac{221}{30} , 7.36 , 7\frac{1}{3}$

Solution:

Lets write each of the above given numbers in a simplified form:

$7\frac{1}{3}$

Simplify this by converting it into a decimal form:

This becomes:

(3*7+1) / 3 = (21 + 1) / 3 = 22/3 = 7.333333

$7\frac{1}{3}$ = 7.3

$\frac{221}{30}$

Simplify this by converting it into a decimal form:

This becomes:

221/30 = 7.3666666667

So,

$\frac{221}{30}$ = 7.367

$7.36$

This number comes with a bar sign on .36 which means that the number has a non terminating repeating decimal expansion as 7.3636363636...

So after rounding it off this becomes:

7.36

$3.16\sqrt{2e}$

Simplify this by converting it into a decimal form:

The value of e = 2.718

This becomes:

3.16 $\sqrt{2*2.718}$

= 3.16 (√5.436)

= 3.16 * 2.331523

= 7.3679949818

= 7.368

$3.16\sqrt{2e}$ = 7.368

7.367995

Now we get the numbers in decimal form:

$7\frac{1}{3}$ = 7.333333 = 7.3

$\frac{221}{30}$ = 7.3666666667 = 7.367

7.36 = 7.3636363636

$3.16\sqrt{2e}$ = 7.3679949818 = 7.368

Now lets order the numbers from greatest to least:

$3.16\sqrt{2e}$

$\frac{221}{30}$

7.36

$7\frac{1}{3}$

So the correct option is:

Option 4

$3.16\sqrt{2e}, \frac{221}{30} , 7.36 , 7\frac{1}{3}$

belle strong is swimming in lochness lake, 230 feet from shore. suddenly she screams for help and starts swimming toward shore a

spin [16.1K]

She's 230 feet from the shore and she starts swimming towards shore at 2ft/s and covers 20 ft then Maxx starts out at 5ft/s at this point 10 seconds will have elapsed ( remember to add this on).They have now to cover 210 ft between them so the ratio will be5:2 making 210 divide by 7 = 30secs. So max will cover 150 ft and belle will cover 60 ft. So in summation for Belle to cover 60ft it would take her 30 secs plus the first 10 secs total 40 secs

What is the real part of the complex number -3+9i

VikaD [51]

The real part of given complex number -3 + 9i is -3

Solution:

We have to find the real part of complex number -3 + 9i

A Complex Number is a combination of real Number and an imaginary Number

The general form of complex number is:

a + bi

Where "a" and "b" are real numbers and i is the unit imaginary number

The given complex number is:

-3 + 9i

On comparing the above complex number with general form of complex number we get,

Real part = -3

Thus real part of given complex number is -3
