Answer:

176 square feet

Step-by-step explanation:

add the areas of the rectangle and triangle

rectangle area is

16 times 8 which is

128

rectangle area is

1/2 times 12 times 8 which is

then add them

128 plus 48 is

A community park is shaped like a trapezoid with a height of 30 yd, a top base of 25yd,and a bottom base of 33yd. The park has a

Likurg_2 [28]

Answer: 819.73 yd²

Step-by-step explanation:

$A_{trapezoid} = \frac{b_{1}+b_{2}}{2}*h$

= $\frac{25+33}{2}*30$

= $\frac{58}{2}*30$

= 29 * 30

= 870

$A_{circle} = \pi r^{2}$

= π(4)²

= 16π

≈ 50.27

Area of the park = $A_{trapezoid} - A_{circle}$

= 870 - 50.27

= 819.73

Use the diagram to determine which statement is true

Dahasolnce [82]

The answer is d.

Finding area of ABCD :

Find side length

side = √3² + 4²
side = 5

2. Apply formula to find area

area = 5²
area = 25

Finding area of GHIA :

area = 4²
area - 16

Finding area of DEFG :

area = 3²
area = 9

Now, let's see whether is true.

Area (ABCD) - Area (GHIA) = Area (DEFG)
25 - 16 = 9
9 = 9

∴ Hence, it is proved √

Can someone tell me step by step how to solve this?

sasho [114]

Answer:

Step-by-step explanation:

I take it that this is some sort of ratio. Start by solving the brackets on the left.

Brackets: 1/3 - 1/10

Brackets: 10/30 - 3/30

Brackets: 7/30

Brackets^2: 49/900

Brackets^2 - 1/5: 49/900 - 180/900

Brackets^2 - 1/5: -131/900

(2/5)^2 = 4/25

The way this read, it should be

$\frac{\frac{-131}{900} }{\frac{4}{25} }$

Which when you invert and multiply becomes

$\frac{-131}{900} * \frac{25}{4}$

which finally becomes

$\frac{-131}{144}$

A line passes through the points (–1, –5) and (4, 5). The point (a, 1) is also on the line.

IgorC [24]

Answer:

a = 2

Step-by-step explanation:

Let's find the equation of the line using the 2 points given.

Let's call -1 as x_1 and -5 as y_1

also, 4 as x_2 and 5 as y_2

The equation of line is :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let's plug the points and get the equation of the line:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y+5=\frac{5+5}{4+1}(x+1)\\y+5=2(x+1)\\y+5=2x+2\\y=2x-3$

Now, to find a, we substitute a in x and 1 in y of the equation of the line we just got:

$y=2x-3\\1=2(a)-3\\1=2a-3\\2a=4\\a=\frac{4}{2}=2$
