Svetradugi [14.3K]

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.

James and Lin got married and got new jobs. Lin earns $3100 more per year than James. Together they earn $81,980. How much does

Bumek [7]

Answer:

The earning to James per year is $ 39,440

The earning of Lin per year is $ 42,540 .

Step-by-step explanation:

Given as :

The total earning of James and Lin together = $ 81,980 per year

The earning of Lin is $ 3100 more per year than James

Let The earning of James = $ J

And The earning of Lin = $ J + $ 3100

So, According to question

The total earning of James and Lin together = $ 81,980 per year

Or, The earning of Lin + The earning of James = $ 81,980 per year

Or, $ J + $ 3100 + $ J = $ 81,980 per year

or, 2 $ J = $ 81,980 - $ 3100

Or, 2 $ J = $ 78880

∴ J = $\frac{78880}{2}$

I.e The earning to James per year = $ 39,440

And The earning of Lin per year = $ 34,440 + $ 3100 = $ 42,540

Hence, The earning to James per year is $ 39,440

And The earning of Lin per year is $ 42,540 . answer

Answer:

$=-39xy+24y$

Step-by-step explanation:

$\mathrm{Multiply\:the\:numbers:}\:6\cdot \:2=12$

$=12xy-3xy-24\cdot \:2xy+12\cdot \:2y\\\mathrm{Multiply\:the\:numbers:}\:24\cdot \:2=48\\=12xy-3xy-48xy+12\cdot \:2y\\\mathrm{Multiply\:the\:numbers:}\:12\cdot \:2=24\\=12xy-3xy-48xy+24y\\\mathrm{Add\:similar\:elements:}\:12xy-3xy-48xy=-39xy\\=-39xy+24y$
