Answer:

h = 430

Step-by-step explanation:

1290 = h/10 + h/5 Make h/5 into something that is something / 10

1290 = h/10 + 2h/(5*2) Clean up the brackets.

1290 = h/10 + 2h/10 Add the right.

1290 = 3h/10 Multiply both sides by 10

1290*10 = 10(3h/10)

12900 = 3h Divide both sides by 3

h = 430

From 1994 to 1995 the sales of a book decreased by 80%. If the sales in 1996 for the same as in 1994, By what percent did the in

zheka24 [161]

Answer:

400%

Step-by-step explanation:

Let the sales be "100" in 1994

Since, it decreased 80%, the sales was:

80% = 80/100 = 0.8

0.8 * 100 = 80 (decreased by 80)

So, it was

Sales in 1995: 100 - 80 = 20

Sales in 1996 was same as in 1994, so that's 100

Thus,

Sales in 1994: 100

Sales in 1995: 20

Sales in 1996: 100

We need to find percentage increase form 1995 to 1996, that is what percentage increase is from 20 to 100?

We will use the formula:

$\frac{New-Old}{Old}*100$

Where

New is 100

Old is 20

SO, we have:

$\frac{New-Old}{Old}*100\\=\frac{100-20}{20}*100\\=4*100\\=400$

So, it increased by 400%

A point is reflected across the x-axis. The new point is located at (4.75, -2.25) Where was the original point located.

sergejj [24]

Answer:

(4.75, 2.25)

Step-by-step explanation:

Given the coordinate (x,y). If this coordinate is reflected over the x axis, the resulting coordinate will be (x, -y)

Note that the y coordinate was negated.

Let the original point needed be (x, y)

If the new point is located at (4.75, -2.25)

Since the y coordinate was negated, then;

-y = -2.25

y = 2.25

x = 4,75 (x coordinate remains the same)

Hence the original point is (4.75, 2.25)

Calculate the area shaded

Rudiy27

Answer:

7.722 cm^2

Step-by-step explanation:

Step 1: Find the area of the square.

Area of square = s^2, where s = side
6^2 = 36 cm^2

Step 2: Find the area of the circle.

We are given the diameter of the circle as 6 cm, so the radius must be 3 cm.
Area of circle is $\pi r^2$ , so now we plug in and simplify.
$3.142 * 3^2$
$3.142 * 9$
$28.278$

Step 3: Subtract area of circle from area of square.

$36 - 28.278$
$7.722$

Therefore, the area of the shaded region is 7.722 cm^2.
