Answer:

8/18=4/9

Step-by-step explanation:

since it there is 1/6 for red marbles and 5/18 for blue marbles it works because it is 8*9=72 for the denominator and 4*3=12 so it is 12/72=1/6 and for blue it is 5/18 because it is 5*4=20 and 20/72=10/36=5/18 so it is 1/6+5/18=8/18=4/9

Red line shows
y=x^2-4 , cause it's going through point (0,-4)

So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down

Can someone please help me
Bad White [126]

Answer:

<h2>L.A. = 384 cm²</h2><h2>S.A. = 640 cm²</h2>

Step-by-step explanation:

Lateral Area:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a traingle:

A_\triangle=\dfrac{bh}{2}

Substitute:

A_\triangle=\dfrac{(16)(12)}{2}=(8)(12)=96\ cm^2

L.A.=4A_\triangle=4(96)=384\ cm^2

Surface Area:

S.A.=B+L.A.

In the base we have the square with side s = 16cm. The formula of an area of a square:

A_\square=s^2

Substitute:

B=16^2=256\ cm^2

S.A.=256\ cm^2+384\ cm^2=640\ cm^2
