Answer:

106 m^2

Step-by-step explanation:

First multiply the shaded area:

12 * 10 = 120

Then multiply the white space:

7 * 2 = 14

Then subtract the white space from the shaded area to find the area of only the shaded area.

120 - 14 = 106

Final answer: 106 m^2

I hope this helps!

An ant crawls at a rate of 216 ft per minute.
AysviL [449]
First, we need to understand the speed formula:

The time used = distance ÷ rate

In this case, the time needed would be:

5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6

When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:

=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)

Factorize 26 and 13,we get:

=2/5 x 6/1
= 12/5 ft or 2.4 ft

Therefore the answer is 12/5ft or 2.4ft.

Hope it helps!

Evaluate the given integral by making an appropriate change of variables, where r is the rectangle enclosed by the lines x - y =
vova2212 [387]
\begin{cases}u=x-y\\v=x+y\end{cases}

\mathbf J=\dfrac{\partial(u,v)}{\partial(x,y)}=\begin{bmatrix}\dfrac{\partial u}{\partial x}&\dfrac{\partial u}{\partial y}\\\\\dfrac{\partial v}{\partial x}&\dfrac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}1&-1\\1&1\end{bmatrix}
\implies\det\mathbf J=2

The area of the region is then given by

\displaystyle\iint_R\mathrm dA=\int_{u=0}^{u=7}\int_{v=0}^{v=6}2\,\mathrm dv\,\mathrm du=84
