Answer: Total cost to make 12 pennants is $52.5.

Step-by-step explanation:

Since we have given that

There is a rectangle and a triangle.

Length of rectangle = 1 ft

Width of rectangle = 3 ft

So, Area of rectangle is given by

$Area=Length\times Breadth \\\\Area=1\times 3\\\\Area=3\ ft^2$

Base of triangle = 1 ft

Height of triangle = 1 ft

So, Area of triangle is given by

$Area=\frac{1}{2}\times base\times height\\\\Area=\frac{1}{2}\times 1\times 1\\\\Area=\frac{1}{2}\ ft^2$

So, Total area of the pennants will be

$3+\frac{1}{2}\\\\=\frac{6+1}{2}\\\\=\frac{7}{2}\ ft^2$

Number of pennants = 12

Cost per square foot of pennant = $1.25

So, Total cost for 12 pennants is given by

$12\times \frac{7}{2}\times 1.25\\\\=\$52.5$

Hence, Total cost to make 12 pennants is $52.5.

What is the solution to the equation 1/square root of 8 = 4^(m + 2)?

Digiron [165]

Take the log (base 4) of both sides of the equation.
$\log_{4}(\frac{1}{\sqrt{8}}) = m + 2$
$\frac{-1}{2} \log_{4}(4^{\frac{3}{2}})-2 = m$
$-2 \frac{3}{4}= m$

The appropriate choice is ...
m = -11/4
