ANSWER

Each triangle:40 cm²

Kite : 80cm²

EXPLANATION

The area of a triangle is

$\frac{1}{2}bh$

The height of the triangle is

$h = \frac{1}{2} (10)=5cm$

and the base is 16 cm.

The area of each triangle is

$= \frac{1}{2}(16)(5) = 40 {cm}^{2}$

2. The total area of the kite is 2 times the area of one triangle.

$= 2 \times 40 = 80 {cm}^{2}$

Answer:the answer is 8

Step-by-step explanation:

because they split up the triangle which makes the height a diffrent number so u divide by 2, 16 divided by 2 = 8.

What is the solutions of the equation 2 (x+2) ^2-4=28

JulsSmile [24]

Answer:

x = 2 x = -6

Step-by-step explanation:

2 (x+2) ^2-4=28

Add 4 to each side

2 (x+2) ^2-4+4=28+4

2 (x+2) ^2= 32

Divide by 2

2/2 (x+2) ^2=32/2

(x+2)^2 = 16

Take the square root of each side

sqrt((x+2)^2) =±sqrt( 16)

x+2 = ±4

Subtract 2 from each side

x+2-2 = -2±4

x = -2±4

x = -2+4 and x = -2-4

x = 2 x = -6

Martha Alison and Scott buy 3.8 pounds of clay Martha used 1 /4 of the clay for a sculpture Scott used 2/5 of the remaining amou

Sever21 [200]

They are left with 0.51 pounds of clay.

Step-by-step explanation:

Given,

Amount of clay bought = 3.8 pounds

Amount used by Martha = $\frac{1}{4}\ of\ clay$

Amount used by Martha = $\frac{1}{4}*3.8=0.95\ pounds$

Amount left after Martha's use= Total amount - amount used by Martha

Amount left = 3.8 - 0.95 = 2.85 pounds

Amount used by Scott = $\frac{2}{5}\ of\ amount\ left$

Amount used by Scott = $\frac{2}{5}*2.85=\frac{5.70}{5}$

Amount used by Scott = 1.14 pounds

Amount left after Scott's use = Amount left after Martha's - Amount used by Scott

Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds

Amount used by Alison = 1.2 pounds

Amount left = Amount left after Scott's use - Amount used by Alison

Amount left = 1.71 - 1.2 = 0.51 pounds

They are left with 0.51 pounds of clay.
