Answer:

426.9 Km²

Step-by-step explanation:

The shaded area is the area of the triangle subtract the area of the circle.

Area of triangle = 0.5 bh ( b is the base and h the perpendicular height )

Here b = 40 and h = 27, thus

Area = 0.5 × 40 × 27 = 20 × 27 = 540 Km²

Area of circle = πr² ← r is the radius

Here the diameter is 12, thus radius = 12 ÷ 2 = 6

Area = π × 6² = 36π ≈ 113.1 Km²

Shaded area = 540 - 113.1 = 426.9 Km²

Abbey is adopting a kitten. Abbey has a rectangular container to bring the kitten home in. The container has a volume of 3,100

solniwko [45]

L=10.6in
H=15.6in
B=?

$\\ \rm\Rrightarrow V=LBH$

$\\ \rm\Rrightarrow 3100.5=10.6(15)B$

$\\ \rm\Rrightarrow 3100.5=159B$

$\\ \rm\Rrightarrow B=\dfrac{3100.5}{159}+19.5$

Can someone help me find this

PSYCHO15rus [73]

Step-by-step explanation:

In triangle,

 XYZ PYZ

XZ = PZ = 12cm

XY = PY = 5cm

YZ = YZ (Common side)

Hence,

As three sides of the two triangles are equal so,

Triangle XYZ is congruent to Triangle PYZ by SAS congruence condition

Y + 3y + 5y = -18 what is the value of y

ANEK [815]

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

$(y+3y+5y)=-18$
$9y=-18$

Step 2: Divide both sides by 9.

$9y/9=-18/9$
$y=-2$

Step 3: Check if solution is correct.

$-2+3(-2)+5(-2)=-18$
$-2-6-10=-18$
$-18=-18$

Therefore, y = -2.
