HELP MEEEEEEEEEEEEEEEEEEEE
uysha [10]

A=0.25^2+2*0.25\sqrt{\frac{0.25^2}{4}+ 1.2^2}Alright, lets get started.

The side of square base is given 0.25 in. (say a)

The height of pyramid is given 1.2 in. (say h)

The formula for surface area A is given below:

A=a^2+2a √(a^2/4+ h^2 )

Putting the value of a and h .

A=a^2+2a\sqrt{\frac{a^2}{4}+ h^2}

Putting the value of a and h

A=0.25^2+2*0.25\sqrt{\frac{0.25^2}{4}+ 1.2^2} \\A=0.0625+ 0.5\sqrt{\frac{0.0625}{4}+ 1.44} \\A=0.0625+ 0.5\sqrt{0.015625 + 1.44} \\A=0.0625+ 0.5\sqrt{1.455}\\A=0.0625+ 0.5*1.20\\A=0.0625+ 0.60\\A = 0.6625 square inches

Hence the area of pyramid is 0.6625 square inches. : Hope it will help :)

The two-way frequency table below shows data on whether medicine was taken and cold length for
ivann1987 [24]

Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69

0.76. 0.31

Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.
