What should be the paper weight

nata0808 [166]

Answer:

6.25 cm

Step-by-step explanation:

$\rho=\dfrac{m}{V} \\\\V_{\text{pyramid}}= A_{\text{base}}\cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{V} \\\\V=120 \cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{40h} \\\\1.6=\dfrac{10}{h} \\\\1.6h=10 \\\\h=\dfrac{10}{1.6}=6.25\text{ cm}$

The LATERAL Surface Area for the shape below is ____________. (assume the bases are the larger faces on the top and bottom.)

Zolol [24]

Answer:

$LA=210\ cm^2$

Step-by-step explanation:

we know that

The lateral area of the figure is given by

$LA=Ph$

where

P is the perimeter of the base (larger faces)

h is the height

Find the perimeter of the base P

$P=2(11+10)=42\ cm$

we have

$h=5\ cm$

substitute in the formula of lateral area

$LA=42(5)=210\ cm^2$

Triangle JKL has vertices J(2,4), K(3,1), and L(3,3). A translation maps the point J to J'(3,3).

ZanzabumX [31]

Answer:
k' = (4,0)

Explanation:
Point J is originally (2,4)
When translated, point J' became (3,3)
We can note that point J was translated 1 unit to the right and 1 unit down.

We will do the same for point k as follows:
Point k is originally (3,1)
Translating it 1 unit and 1 unit down will result in:
k' = (3+1 , 1-1) = (4,0)

Hope this helps :)
