Step 1 ) Create equation.

\displaystyle\ 8 - 2\frac{1}{4}

Step 2 ) Convert mixed number into improper fraction.

\displaystyle\ 2 \frac{1}{4}

↓

\displaystyle\frac{9}{4}

Step 3 ) Convert whole number to fraction.

8

↓

\displaystyle\frac{8}{1}

Step 4 ) Create new equation.

\displaystyle\ 8 - 2\frac{1}{4}

↓

\displaystyle\frac{8}{1} - \frac{9}{4}

Step 5 ) Re-write equation so that each have common denominators.

\displaystyle\frac{32}{4} - \frac{9}{4}

Step 6 ) Subtract the numerators.

\displaystyle\frac{32}{4} - \frac{9}{4}

↓

\displaystyle\frac{23}{4}

Bonus Step ) Convert to mixed fraction.

\displaystyle\frac{23}{4}

↓

\displaystyle\ 5 \frac{3}{4}

The answer is now in simplest form, this means the final amount of fabric left is..

\displaystyle\ 5 \frac{3}{4}

or it could also be...

\displaystyle\frac{23}{4}

Both are correct, the only difference is that one is in the simplest form.

If Sheila started with 8 yards of fabric and used 2 1/4 yards, she will have the difference of these two values remaining. Subtract 2 1/4 from 8.

Convert the mixed fraction to an improper fraction. (Multiply its denominator by the whole number and replace the numerator with this new number.)

2 1/4 = 9/4

We now have:

8/1 - 9/4

Multiply 8/1 by 4/4 to get common denominators.

8/1 × 4/4 = 32/4

Now subtract.

32/4 - 9/4 = 23/4 = 5.75

Alternatively, we could have converted the fraction 2 1/4 to decimal form and subtracted it from 8.

2 1/4 = 2.25

8 - 2.25 = 5.75

Answer:

Sheila has 5.75 yards of fabric left.

Which one do i choose fam? I suck at geometry
Viefleur [7K]
The best choice would probably be the third option from the top. Since by using the distance formula you can solve for the length or distance of each of the sides of the triangle, and check to see if it is equal. As would be in an equilateral triangle.

Slope wouldn’t be best for the last leg or bottom leg as there is no change in y and x.

Step-by-step explanation:

The graph shifts one unit up the y axis since there's a value outside the absolute value which directly adds 1 to it.

A(x) = -0.015x^3+1.05xA ( x ) = − 0.015 x 3 + 1.05 x gives the alcohol level in an average person's blood x hrs after drinking 8
goldfiish [28.3K]

Answer:

Yes

Step-by-step explanation:

the function that gives the alcohol level is:

A ( x ) = - 0.015 x^3 + 1.05 x

where x is the number of hours.

we need to know if after 4 hours an average person is legally drunk, thus:

x=4

and we substitute this in the function:

A ( 4 ) = - 0.015 (4)^ 3 + 1.05(4)

solving these operations we obtain:

A(4)=-0.015(64)+4.2\\A(4)=-0.96+4.2

A(4)=3.24

the alcohol level after 4 hours is 3.24.

Since a person is considered to be legally drunk if the level exceeds 1.5, and we obtained 3.24 which is greater than 1.5, a person who has been drinking for 4 hours under the conditions indicated by the problem would be considered legally drunk.
