Answer:

The average was 259.24 in 1996.

Step-by-step explanation:

In order to find the year that the average, "y", is 259.24 we need to apply this value on the given expression, as done below:

[tex]259.24 = 0.15*x + 255.34\\0.15*x = 259.24 - 255.34\\0.15*x =3.9\\x = \frac{3.9}{0.15}\\x = 26[/tex]

The average was 259.24 after 26 years, therefore it was in 1996.

Answer:

If 1 pint is equal to 2 cups, then 5 pints would equal _5_ cups.

Step-by-step explanation:

Let's use a ratio to solve:

pints : cups

  1      :   2

  2     :   4

  3     :   6

  4     :   8

  5     :   10

There would be 10 cups in 5 pints.

Step-by-step explanation:

m - 1/m = 3

([tex](m-\frac{1}{m})^{2} = 9\\m^2 - 2 + \frac{1}{m^2} = 9\\ m^2 + \frac{1}{m^2}) = 11\\ \\[/tex]

Out of the 0 + 3 + 1 + 2 + 2 + 4 = 12 trials, the numbers 4, 5, and 6 (the numbers greater than 3) appeared 2 + 2 + 4 = 8 times so the probability is 8 / 12.

Answer:

The x-intercepts are (-2, 0) and (4, 0). I know this because it's written in intercept notation. To find the y-intercept we'll expand.

-(x + 2)(x - 4) = -x² + 2x + 8 so the y-int. is (0, 8). To find the rest we'll complete the square.

-x² + 2x + 8 = -(x² - 2x) + 8 = -(x -1)² + 1 + 8 = -(x - 1)² + 9 so the vertex is (1, 9) and the axis of symmetry is x = 1. This means that the domain is all real numbers and the range is y ≤ 9.

Answer:

Surface area of the figure = 1000 in²

Step-by-step explanation:

From the figure attached,

Two rectangular prisms A and B have been shown with the dimensions.

Surface area of a rectangular prism = 2(length + width) × height

Surface area of prism A = 2(9 + 10) × 20

                                        = 760 in²

Surface area of prism B = 2(15 + 10) × 8

                                        = 16×25

                                        = 400 in²

But one surface of prism B along the width and the same area of prism A are hidden.

Area of the hidden surfaces = 2(10 × 8)

                                               = 160 in²

Total surface area of the figure = 760 + 400 - 160

                                                    = 1000 in²

Answer:

2/3 hours or 40 mins.

Step-by-step explanation:

No. of trees planted by David = 11

No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3

It takes him about the same amount of time to plant each tree

let time taken to plan 1 tree be x

then  time taken to plan 1*11 tree = 11*x

But, given that total time taken is 22/3 hours

thus,

11x = 22/3 hours

x = 22/(3 *11) = 2/3

Thus, it took 2/3 hours to plant each tree.

As 1 hour has 60 minutes

Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins

It takes David 2/3 hours to plant each tree.

Since it takes David 7 1/3 hours today to plant 11 trees.

Therefore time taken to plant 11 trees = 7 1/3 hours = 22/3 hours

The time taken to plant each tree = 22/3 hours ÷ 11 trees = 2/3 hours per tree

Therefore it takes David 2/3 hours to plant each tree.

Answer:

Answer = 2,335.52

Step-by-step explanation:

Given amount : 1,885

Finding 5%  of 1,885 =  0.05 * 1,885

5% of 1885 = 94.25

Now 1885 increased by 5% =  1,885 + 94.25= 1,979.25

Finding further 18% of 1,979.25 = 0.18 * 1,979.25

18% of 1979.25 = 356.265

Final amount = 1,979.25 + 356.265

Final Amount = 2,335.515

Now Rounding off the answer to 2 decimal points we get:

Answer = 2,335.52

(As the third digit after decimal is 5 so previous will be added b 1)

Answer:

|AC| = 4.47 units (question attached as image)

Step-by-step explanation:

The question lacks sufficient details. We wil however consider a similar example (image attached) to understand how to solve questions using Pythagoras theorem.

We will calculate for |AC| using Pythagoras theorem, we have:

|AC|² = |AB|² + |BC|²

|AC| = ?, |AB| = 4 units, |BC| = 2 units

|AC|² = 4² + 2² = 16 + 4

|AC|² = 20 ⇒ |AC| = [tex]\sqrt{20}[/tex]

|AC| = 4.472135955 ≈ 4.47

|AC| = 4.47 units

Answer:

She expect 9  postcards to be delivered within a week.

Step-by-step explanation:

We are given that The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62

We are also given that The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.

Now we are supposed to find How many of her postcards can she expect to be delivered within a week if She posts 15 postcards to the UK on Monday.

So, The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week =0.62

She expect no. of postcards to be delivered within a week.= [tex]15 \times 0.62[/tex]

She expect no. of postcards to be delivered within a week.=9.3

So, She expect 9  postcards to be delivered within a week.

Answer:

the answer is 20.1 yd

Step-by-step explanation:

circumference= 2πr

where r is 3.2

pi is 22/7

c = 2/1 × 22/7 × 3.2/1

c = 140.8/7

c = 20.1 yd

The circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have a circle shown in the picture.

The radius of the circle = 3.2 yd

As we know,

The circumference of the circle can be calculated using the formula:

C = 2πr

Here,

C is the circumference of the circle

r is the radius of the circle

r = 3.2 yd

C = 2π(3.2)

Take π = 22/7

C = 6.4π(22/7)

C = 140.8/7

C = 20.114

After round to the nearest tenth:

≈ 20.12 yd.

Thus, the circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.

Answer: 16 + 55 = 71cm^2

Step-by-step explanation:

You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.

First One:

It has the dimensions of 5 and 11. 5 x 11 = 55cm^2

Second One:

This one wont be straightforward like the first one. You need to find these sides manually.

7 + x = 11

x = 4

Then,

9 - x = 5

x = 4

4 x 4 = 16cm^2

(fx) or y is 2 when x bigger than 3. so, 3 is not included. so you must draw straight horizontal line at y = 2 start from x = 3 to the right with empty circle first (it means 3 not included)
