Which formulas can be used to find the surface area of a right prism where p is the perimeter of the base, h is the height of th
svp [43]
Let
ba--------> area of bases (<span>the two bases included</span>)
p---------> perimeter of the base
h--------> height of the prism  
la-------> lateral area

we know that

[surface area]=2*[area of one base]+[perimeter of the base]*height 
so
2*[area of one base]=ba
[surface area]=[ba]+[p]*h

and 
the formula of lateral area is
[la]=[perimeter of the base]*height
[la]=[p]*h
therefore
[surface area]=[ba]+[la]

the answer is
[surface area]=[ba]+[p]*h
[surface area]=[ba]+[la]

Calculate the median of the data set below. {0.3, 1.5, 3.8, 2.6, 1.5, 9.1, 4.2, 3.8, 1.5, 2.9} A. 3.8 B. 3.35 C. 2.75 D. 2.5
vekshin1

Answer:

2.75

Step-by-step explanation:

0.3,1.5,1.5,1.5,2.6,2.9,3.8,3.8,4.2,9.1

(smaller to greater)

middle of this is 2.6 and 2.9

so, 2.6+2.9=5.5

now we divide it by 2

so, 5.5/2=2.75

Perform the indicated operation. 22 6/7 ∙ 1 1/2
gavmur [86]

Answer:

34\frac{2}{7}

Step-by-Step Explanation:

Given:

The expression to simplify

22\frac{6}{7}\times 1\frac{1}{2}

Convert the mixed fractions to improper fractions. This gives,

22\frac{6}{7}=\frac{22\times 7+6}{7}=\frac{160}{7}\\  1\frac{1}{2}=\frac{1\times 2 + 1}{2}=\frac{3}{2}

Now, we multiply to simplify.

\frac{160}{7}\times \frac{3}{2}= \frac{160\times 3}{7\times 2}=\frac{80\times 3}{7}=\frac{240}{7}=34\frac{2}{7}

Therefore, the product of 22\frac{6}{7}\textrm{ and }1\frac{1}{2} is 34\frac{2}{7}.
