4 0

<u>Answer:</u>

<h2>4. A = 1029 cm²</h2>

<u>Steps:</u>

A = (35×21)+(21+2×3.5)×21/2

A = 735 + (21+7)×21/2

A = 735 + 28×21/2

A = 735 + 588/2

A = 735 + 294

<h2>A = 1029 cm²</h2>

Please help e and my sister want to go somewhere but we cant because of this​
gtnhenbr [62]

Answer:

1 5/12 lb

Step-by-step explanation:

This is a subtraction problem.

He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.

Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.

We start with the

subtraction below

       4 2/3

  -    3 1/4

---------------

The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.

We use the LCD to get

the subtraction below

       4 8/12

  -    3 3/12

----------------

Now we subtract the whole numbers and the fractions.

       4 8/12

  -    3 3/12

----------------

       1 5/12

Answer: 1 5/12 lb

Ad libitum [116K]

\frac{2}{3}  \div  \frac{1}{6}
{is the same as / equal to:}
\frac{2}{3}  \times  \frac{6}{1}  \\  =  \frac{2}{3}  \times 6 \\  =  \frac{2 \times 6}{3}  \\  =  \frac{12}{3}
{Simplify the fraction to become:}
= 12 \div 3 \\  = 4

Hope this helps! :)

Which input value produces the same output value for the two functions on the graph?
DiKsa [7]

Answer:

The input value is 3/4

Step-by-step explanation:

we know that

The input value that produces the same output value for the two linear functions, is the intersection point both graphs

we have

f(x)=-3x+1 ---> equation A

g(x)=x-2 ---> equation B

Equate equation A and equation B

x-2=-3x+1

solve for x

3x+x=1+2

4x=3

x=\frac{3}{4}

therefore

The input value is 3/4
