Pat's average weekly income from her part time job was 15% more in September than it was in July. her average weekly income in July was 10% less than it was in August. if her average weekly income in September was $207, what was her average weekly income in August?​

Answers

Her average weekly income in August was $200.

Step-by-step explanation:

To find the income in july :

Given that,

Her average weekly income in September was $207.Her part time job was 15% more in September than it was in July.

Let,

'x' be the 100% of income she got in July.

Therefore, the income $207 in September is 115% of x.

⇒ 115% of x = 207

⇒ 1.15 × x = 207

⇒ x = 207 / 1.15

⇒ x = 180

∴ Her average weekly income in July was $180.

To find the income in August :

Given that,

Her average weekly income in July was 10% less than it was in August.We found that, $180 is the average weekly income in July which is 10% less than August.

Let,

'y' be the 100% of income she got in August.

Therefore, the income $180 in July is 90% of y.

⇒ 90% of y = 180

⇒ 0.9 × y = 180

⇒ y = 180/0.9

⇒ y = 200

Her average weekly income in August was $200.

her average weekly income in August was $200 .

Step-by-step explanation:

Let in July income was x , So in September :

⇒ [tex]x+\frac{15x}{100}[/tex]

According to question , her average weekly income in September was $207 i.e.

⇒ [tex]x+\frac{15x}{100}=207[/tex]

⇒ [tex]\frac{115x}{100}=207[/tex]

⇒ [tex]x=207(\frac{100}{115})[/tex]

⇒ [tex]x=180[/tex]

Now , average weekly income in July was 10% less than it was in August , let income of august = y,  i.e.

Income in august = [tex]180+\frac{August(10)}{100}[/tex]

⇒ [tex]y=180 + \frac{y(10)}{100}[/tex]

⇒ [tex]\frac{9}{10}y=180[/tex]

⇒ [tex]y=\$200[/tex]

Therefore , her average weekly income in August was $200 .

The circumference of a circle is 48 pie units. What is the radius of the circle

Answers

Answer:

r = 24

Step-by-step explanation:

The formula for circumference is

C = 2*pi*r

48 pi = 2 * pi *r

Divide each side by  2pi

48 pi / 2pi = 2 * pi *r/ 2pi

24 = r

Describe what Pi is and explain how it is used in finding the circumference of a circle

Answers

Pi is 3.14. You use it to find the circumference of a circle by multiplying pi, 2, and the radius of the circle.

Answer:

Sample response: Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.

the length of a rectangle is six times it’s width. If the perimeter of the rectangle is 112 yards, find it’s length and width.

Answers

The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.

Step-by-step explanation:

The given is,

                   The perimeter of the rectangle is 112 yards

                   The length of a rectangle is six times it's width

Step:1

          Let, p - Perimeter of the rectangle

                   l - Length of the rectangle

                 w - Width of the rectangle

Step:2

        Formula for perimeter of rectangle,

                    [tex]Perimeter, p = 2(l+w)[/tex]............................(1)

        From given,

                      p = 112 yards

                       l = 6w                            ( ∵ From given)

                     w = w

        Substitute the values,

                   112 = 2 ( 6w + w )

                   112 = 2 ( 7w )

                   112 = 14w

                    w = 8 yards

         From the w value, l becomes

                     l = 6w

                     l = 6 × 8

                   l  = 48 yards

Result:

       The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.

4) -8 – 3a = 46 whoever has best answer gets brainliest

Answers

Answer:

A= -18

Step-by-step explanation:

-8-3(-18)= 46= -18

Answer:

a=-18

Step-by-step explanation:

Let's break this down step by step.

-8-3a=46

Since 3a has a variable, a, we want to get it by itself. So the first step is to do the inverse operation and add 8 on both sides. That leaves this equation:

-3a=54

The 3a is -3a because of the subtraction sign in front. Now we divide on both sides because we want the variable, a, to be by itself. That leaves this simplified expression.

a=-18.

Now, let's work it out in context of the problem.

-8-3x-18=46

3x-18 is -54, and -8-(-54), it would become 46.

Not on there but it is 76in2

Step-by-step explanation:

Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.

Which set of line segments could create a right triangle? (4 points)
O 15,30,35
O 15,36,39
O 15, 20, 29
O 5,15,30

Answers

Answer:

(B)15,36,39

Step-by-step explanation:

To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.

By Pythagoras Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]

In  15,30,35

[tex]35^2\neq 15^2+30^2\\1225\neq 1125[/tex]

In 15,36,39

[tex]39^2=36^2+15^2\\1521=1521[/tex]

In 15, 20, 29

[tex]29^2\neq 15^2+20^2\\841\neq 625[/tex]

In 5,15,30

[tex]30^2\neq 15^2+5^2\\900\neq 250[/tex]

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.

¿Cuál dígito debe ir en el recuadro para

Answers

Answer:

7

Step-by-step explanation:

English:

Which digit should go in the box to

make the next number divisible

between 2, 3 and 9? 8 ,? 48

Let x be the number, then the number will look like this:

8x48

This number is already divisible by 2, because it ends with an even number.

Now we need to check for divsibility by 3.

For this to be divisible by 3, the sum of the digit should be a multiple of 3.

[tex]8 + x + 4 + 8 = x +20[/tex]

We know if a number is divsible by 9, it is also divsible by 3.

So

[tex]x + 20=9,18,27,....[/tex]

The least positive solution is

[tex]x + 20 = 27[/tex]

[tex]x = 27 - 20[/tex]

[tex]x = 7[/tex]

Therefore 8748 is divsible by 2,3, and 9.
