1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields
$\frac{19}{4} * \frac{12}{5} =$
$= \frac{57}{5} = 11.4 ft^{2}$

Part 2:
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:
$\frac{69}{10} / \frac{3}{8} = \frac{69}{10} * \frac{8}{3} = \frac{92}{5}$
since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is 18 cutouts

Find the distance between the point (2, 3) and the line 4x + 3y = 10 (round your answer to the nearest tenth).

Monica [59]

Explanation

Let's first graph the elements:

Using the distance formula we get:

$d=\frac{|4(2)+3(3)-10|}{\sqrt{4^2+3^2}}$ $d=\frac{|7|}{\sqrt{25}}=\frac{7}{5}=1.4$

pedro earned gross income of 35200 last year. if he took the standard deduction of 5450 and one exemption of 3500, what was his

Elenna [48]

Answer:

33250

Step-by-step explanation:

Pedro had earned a gross income of 35200 last year.

So, the gross income of Pedro for the current year will also be 35200.

But, this year he has taken the standard deduction of 5450.

Hence, his current year's income will be reduced to (35200-5450)= 29750.

Again, in the current year, he got an exemption of 3500.

Therefore, the net taxable income of Pedro for the current year will become (29750+3500) =33250. (Answer)
