9/10 + 3/5

liubo4ka [24]

Answer:

15/10

Step-by-step explanation:

Since it is adding you need to get a common denominator(bottom number).

I know that 2 × 5 = 10 so now we multiply 3/5 × 2

we get 6/10

now the problem is 9/10 + 6/10

9 + 6 = 15 and the denominator is 10

15/10

What is the total surface area of this square pyramid?

slamgirl [31]

Answer:

The total surface area of this square pyramid is $297\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

$SA=b^{2} +4[\frac{1}{2}(b)(h)]$

we have

$b=9\ mm$ ----> the length side of the square base

$h=12\ mm$ ----> the height of the triangular faces

substitute the values

$SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}$

Write the equation of the line with a slope of 1/6 that contains (12,-7)

tatiyna

$\bf (\stackrel{x_1}{12}~,~\stackrel{y_1}{-7})~\hspace{10em} slope = m\implies \cfrac{1}{6} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-7)=\cfrac{1}{6}(x-12) \\\\\\ y+7=\cfrac{1}{6}x-2\implies y=\cfrac{1}{6}x-9$
