Answer:

51 $units^{2}$

Step-by-step explanation:

You can split the polygon into two shapes, a triangle and a square. First, let's find the area of the square. The length of this figure is 7 and the height is 6. So, all we do is multiply 7 times 6 and get the area of the square to be 42.

Next, let's find the area of the triangle. The formula to find the area of a triangle is: $\frac{1}{2} bh$ . The base (or length) of this figure is going to be 6, while the height of this figure is going to be 3. We can then plug in these numbers into the formula: $\frac{1}{2}(6)(3)$ . This gives us the answer of 9.

We then can add these numbers up and get the area of the polygon to be 51 squared units.

Answer:

Step-by-step explanation:

I think it's 50 because the length is 10 units long And the width is 5 units long and when you do area, you multiply the width times length.

convert the linear equation 3x-2y=5 to point slope form. use the point with an x-coordinate equal to 1

Mademuasel [1]

When x = 1, y = (5 - 3) / -2 = -1 , let x1 = 1 and y1 = -1
2y = 3x - 5
so slope = 3/2

y - y1 = m(x - x1)

y -(-1) = (3/2)(x - 1)

y + 1 = 3/2 ( x - 1) <----- answer

Which of the following options have the same value as 30\%30%30, percent of 818181?

Nataly_w [17]

Answer:

Option B is correct = $0.3 \times 81$

Step-by-step explanation:

The complete question is: Which of the following options have the same value as 30% of 81?

Group of choices is:

(A) $\frac{30}{100}\times 81 \times 100$

(B) $0.3 \times 81$

(D) $\frac{3}{10}\times 81 \times 10$

(E) $30 \times 81$

Now, the expression given to us is 30% of 81.

Simplifying the above expression we get;

30% of 81 = $\frac{30}{100} \times 81$

= $\frac{3}{10} \times 81$ = $0.3 \times 81$

Now, we will solve each of the given options and then see which option matches with our calculation.

Option (A) is given;

$\frac{30}{100}\times 81 \times 100$ = $30 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (B) is given;

$0.3 \times 81$

This matches with our answer, so this option is correct.

Option (C) is given;

$0.03 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (D) is given;

$\frac{3}{10}\times 81 \times 10$ = $3 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (E) is given;

$30 \times 81$

This doesn't match with our answer, so this option is not correct.
