Answer 1

Answer:

The area is 2,600 cm^2

Step-by-step explanation:

The area of a rectangle is the product of its sides

And the difference between both areas is 1,400 cm^2 (P-Q)

Thus, we have it that;

40(3x-10) - (30(x + 15)) = 1,400

120x - 400 - 30x - 450 = 1400

120x -30x -400-450 = 1400

90x - 850 = 1400

90x = 1400 + 850

90x = 2,250

x = 2,250/90

x = 25

The area for painting P

is;

40 (3x - 10)

Substituting the value 25 for x

we have

40 ( 3(25) -10)

= 40(75-10)

40 * 65 = 2,600 cm^2

Joseph operates a consulting business. He uses his personal credit card for both business and personal use. The total finance charges paid for the year were $957. Joseph's total business charges on the card were 41% of all the charges. What amount of interest expense can be deducted on Joseph's Schedule C

Answers

Answer:

$392.37

Step-by-step explanation:

Data provided in the question:

The total finance charges paid for the year = $957

Joseph's total business charges on the card = 41% of all the charges

Now,

The amount of interest expense can be deducted on Joseph's Schedule C will be the Joseph's total business charges on the card

Therefore,

The amount of interest expense can be deducted on Joseph's Schedule C

= 41% of $957

= 0.41 × $957

= $392.37

Jason’s Cookie Store allocates 12% of its annual budget to supplies. It spends $42,153 annual on supplies. What is the annual budget of Jason’s Cookie Store?

Solve the system by graphing. Write the solution as an ordered pair. y = 1/3x + 2 y = –x – 2Help me please....I need good grades

Answers

ANSWER

The solution is where the two graphs intersect, which is
$(-3,1).$

EXPLANATION

The given system of equations are
$y = (1)/(3) x + 2$
and

$y = - x - 2$

We need to graph the two equations.

Let us graph

$y = (1)/(3) x + 2$
first.

We need at least two points.

You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.

When
$x = 0$

$\Rightarrow \: y = (1)/(3) (0) + 2$

$\Rightarrow y = 0 + 2$

$\Rightarrow y = 2$

So this gives us the ordered pair,

$(0,2)$

When
$y = 0$
we get,

$0= (1)/(3) x + 2$

$\Rightarrow \: - 2 = (1)/(3) x$

$\Rightarrow \: - 2 * 3= x$

$\Rightarrow \: -6= x$
This also gives the ordered pair

$(-6,0).$

We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.

For the second line

We again find the intercepts and plot them.

When
$x = 0$

$y = - 0 - 2$

$\Rightarrow \: y = - 2$

This gives the ordered pair

$(0,-2)$

Also, when
$y = 0$

then we have,

$0 = - x - 2$

$2 = - x$

$x = - 2$

Then we again have the ordered pair,

$(-2,0)$

We plot these two points on the same graph sheet to obtain the red graph above.

The intersection of the two lines is
$(-3,1)$
