Answer:

1 11/12

Step-by-step explanation:

Simplify 3\times 43×4 to 1212.

\frac{12+1}{4}-1\frac{1}{3}

12+1

−1

3 Simplify 12+112+1 to 1313.

\frac{13}{4}-1\frac{1}{3}

−1

4 Convert 1\frac{1}{3}1

to improper fraction. Use this rule: a \frac{b}{c}=\frac{ac+b}{c}a

ac+b

5 Simplify 1\times 31×3 to 33.

13/4 -3 +1 / 3

6 Simplify 3+13+1 to 44.

13/4-4/3

7 (Find the Least Common Denominator (LCD) of 13/4,4/3 In other words, find the Least Common Multiple (LCM) of 4,34,3.)

LCD = 1212

8 (Make the denominators the same as the LCD)

13 x 3 - 4 x 4

4 x 3 -3 x4

9 (Simplify. Denominators are now the same.)

39/12-16/12

10 (Join the denominators.)

39-16

39−16

11 Simplify.

23/12

12 (Convert to mixed fraction.)

Mazyrski [523]

Answer:

The correct equation is "y=30x+6147". A further explanation is given below.

Step-by-step explanation:

The given values are:

(x1, y1) = (50, 7647)

(x2, y2) = (100, 9147)

As we know,

The slope is,

⇒ $m=\frac{y2-y1}{x2-x1}$

On substituting the given values, we get

⇒ $=\frac{9147-7642}{100-50}$

⇒ $=\frac{1500}{50}$

⇒ $=30$

Now,

⇒ $(y-y1)=m(x-x1)$

On substituting the given values in the above equation, we get

⇒ $y-7647=30(x-50)$

⇒ $y-7647=30x-1500$

On adding "7647" both sides, we get

⇒ $y-7647+7647=30x-1500+7647$

⇒ $y=30x+6147$

The designer sketched a model of the pond. The model drawing had a circumference of 24 inches. What is the AREA of the model she

Delicious77 [7]

Answer:

Area of model pond = 45.6 inch² (Approx.)

Step-by-step explanation:

Given:

Circumference of circular pond = 24 inches

Find:

Area of model pond

Computation:

Circumference of circle = 2πr

Circumference of circular pond = 2πr

24 = 2[22/7][r]

Radius r = [24 x 7] / [2 x 22]

Radius r = 3.81 inch (Approx.)

Area of circle = πr²

Area of model pond = πr²

Area of model pond = (22/7)(3.81)²

Area of model pond = [3.1428][14.5161]

Area of model pond = 45.6 inch² (Approx.)

1/2(6 2/3+1/4)-5/24=

Helen [10]

For this case we must simplify the following expression:

$\frac {1} {2} (6 \frac {2} {3} + \frac {1} {4}) - \frac {5} {24} =$

We convert the mixed number to an improper fraction:

$6 \frac {2} {3} = \frac {3 * 6 + 2} {3} = \frac {20} {3}$

So, by rewriting we have:

$\frac {1} {2} (\frac {20} {3} + \frac {1} {4}) - \frac {5} {24} =\\\frac {1} {2} (\frac {4 * 20 + 3 * 1} {4 * 3}) - \frac {5} {24} =\\\frac {1} {2} (\frac {80 + 3} {12}) - \frac {5} {24} =\\\frac {1} {2} (\frac {83} {12}) - \frac {5} {24} =$

$\frac {83} {24} - \frac {5} {24} =\\\frac {83-5} {24} =\\\frac {78} {24} =\\\frac {39} {12} =\\\frac {13} {4} =\\3 \frac {1} {4}$

Answer:

$3 \frac {1} {4}$
