Answer:

12√3

1) To find out the Lateral Area of this pyramid we need to calculate the area of those three equilateral triangles.

$\begin{gathered} Lateral_(Area)=3(s^2\frac{\sqrt[]{3}}{4})=3(16\frac{\sqrt[]{3}}{4}) \n L=3\cdot4\sqrt[]{3} \n L=12\sqrt[]{3} \end{gathered}$

2) Hence, the Lateral Area of that pyramid is 12√3 u²

Find the smallest number by which 240 must be multiplied so that the product is a perfect square. *

Answers

Answer:

Step-by-step explanation:

$240 = 2 * 2 * 2 * 2 * 3 * 5 \n = {2}^(4) * 15 \n$

Here, 15 is not a square number so, 240 should be multiplied by 15 to make 240 as perfect square.

240* 15 = 3600

Find the slope (m) and the y-intercept (b) of the given line on the graph. pls show work/explanation!

Answers

Answer:

Slope: 1; Y-int: (0,2)

Step-by-step explanation:

The slope is rise over run, the equation is y two minus y one divided by x two minus x one.

(3-2) / (1-0) = 1

The y-int. is where the line crosses the y-axis, or the x value is 0.

The perimeter of a rectangle, P, is given by P = 2L + 2W, where L is its length and W is its width. What is the perimeter of a rectangle of length 9 ft and width 13 ft?

Answers

Answer: 44 ft

Step-by-Step Explanation:

Length (L) = 9 ft
Width (W) = 13 ft
Perimeter (P) = 2L + 2W

Substitute values of ‘L’ and ‘W’ :-

= 2L + 2W
= 2(L + W)
= 2(9 + 13)
= 2(22)
= 2 * 22
=> 44

Hence, Perimeter (P) = 44 ft
