Answer:

Step-by-step explanation:

area = ½(base)(height) = 2x²-2x-4

½(base)(x-2) = 2x²-2x-4

½(base) = (2x²-2x-4) ÷ (x-2) = 2x+2

base = 4x+4

Answer:

B) (4/9 x 20)-3

Answer:

100π

Step-by-step explanation:

The formula for area of a circle is:

π[tex]r^{2}[/tex]

The radius is 10 feet.

[tex]10^{2}[/tex] is 100

This makes the expression representing the area of the circle:

100π

Answer:

75%

Step-by-step explanation:

First find the number of boys.

80 - 20 = 60

Now find the percentage my taking the number of boys upon the total, times that by 100 which gives the percentage.

[tex]\frac{60}{80}[/tex] × 100 = 75%

I agree with Tommy because the sum of the smallest obtuse angles (91+91⁰) is 182⁰ which is a reflex angle, not obtuse. The other obtuse angles will be bigger and so will not be obtuse either.

Answer:

58

Step-by-step explanation:

45=((3x+11)+(10x-12))÷2

90=13x-1

13x=91

x=7

ML=10(7)-12

    =58

Using midline interval, the value of ML is 58.

The distance from the "midline of the interval to either end line is called midline interval".

According to the question,

The line JK is 3x+11, the line ML is 10x - 12. In order to find the value of ML.

The formula to calculate value of ML is midline value =  [tex]\frac{(x1 + x2)}{2}[/tex].

Let x₁ = 3x + 11 and x₂ = 10x - 12

45 = [tex]\frac{(3x + 11) + (10x - 12 )}{2}[/tex]

90 = 3x + 11 + 10x -12

     = 13x -1

13x = 91

   x = 7

Substitute x = 7, in equation x₂ we get 10(7) - 12 = 70 - 12 = 58.

Hence, using midline interval the value of ML is 58.

Answer:

21/56 in simplest form is 3/8

Step-by-step explanation:

Answer:

14 items

Step-by-step explanation:

What we know:

- it takes 7 seconds to process the payment

- for every item, it takes 1.5 seconds to scan

- in total, it took 28 seconds to ring up the customer

With these pieces of information, we can construct the following equation:

[tex]28=1.5x+7[/tex] when [tex]x[/tex] is equal to the number of items there is

Subtract both sides by 7

[tex]28-7=1.5x+7-7\\21=1.5x[/tex]

Divide both sides by 1.5

[tex]\frac{21}{1.5} =\frac{1.5x}{1.5} \\14=x[/tex]

Therefore, 14 items were being purchased.

Answer:

Mean: 10.3

Median: 12

Mode: 13

Range: 15

Step-by-step explanation:

First, let's define what all these terms mean.

Mean is the average of all the numbers in a set of data. Median is the number in the middle of a range whenever the numbers are put in ascending order. If there are two numbers in the middle instead of one, then take the average of those two numbers. Mode is the number that occurs the most in the set of data. Range is the difference between the largest and the smallest number in a set of data.

To make things a little easier overall, let's just go ahead and put all our numbers in ascending order, which will be as follows: 1, 6, 7, 7, 11, 13, 13, 13, 16, 16.

To find the mean, just add up all the numbers and divide by how many there are. So we'll add 1 + 6 + 7 + 7... and so on to get a total of 103. Next, we'll divide that number by 10 since there are 10 students. This gives us a mean of 10.3.

Next, we'll find the median. To find this, just figure out which number(s) is in the center of your data. Since we have an even number of terms (10), we'll have two numbers in the middle, being 11 and 13. To find our median from here, just add 11 and 13 and then divide by 2. 11 + 13 = 24 and then 24 / 2 = 12. This means that our median is 12.

Next, we'll find the mode. The mode is the number that is seen the most in a set of numbers. In our set, we see that there are three 13s. Since 13 is the most frequently used number in our set, this makes it the mode.

Finally, we'll find the range. The range is just the largest number in the set minus the smallest number in the set. In our set, 16 is our largest number and 1 is our smallest. Just do 16 - 1 = 15 and we'll see that 15 is the range of the set. Hope this helps!

Answer:

Linda has 3/8 yards of fabric left.

Step-by-step explanation:

Ok, so forget 1 "yard." That'll just confuse you. Just say, Linda has 1. She used 5/8 of it. How much does she have left? So, Linda breaks her 1 into 8 pieces, and she throws away 5 of them. How many does she have left? Basically, just subtract 5 from 8. What does that give you? 3! Linda has 3/8 yards of fabric left.

Answer:

The points are (1, -11) and (17, -11).

Step-by-step explanation:

The distance between points (x1, y1) and (x2, y2) is

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

We have values for x1, y1, and y2. We leave x for x2, and we solve for x.

[tex] 17 = \sqrt{(x - 9)^2 + (-11 - 4)^2} [/tex]

Square both sides.

[tex] 289 = (x - 9)^2 + (-11 - 4)^2 [/tex]

[tex] 289 = x^2 - 18x + 81 + 225 [/tex]

[tex] x^2 - 18x + 17 = 0 [/tex]

[tex] (x - 1)(x - 17) = 0 [/tex}

[tex] x - 1 = 0 [/tex]   or   [tex] x - 17 = 0 [/tex]

x = 1 or x = 17

The points are (1, -11) and (17, -11).

Using distance between two points, it is found that the values are:  x = 17, x = 1.

----------------------------

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

----------------------------

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\sqrt{(x - 9)^2 + (-11 - 4)^2} = 17[/tex]

[tex](\sqrt{(x - 9)^2 + (-11 - 4)^2})^2 = 17^2[/tex]

[tex](x - 9)^2 + (-15)^2 = 289[/tex]

[tex]x^2 - 18x + 81 + 225 = 289[/tex]

[tex]x^2 - 18x + 17 = 0[/tex]

Quadratic equation with [tex]a = 1, b = -18, c = 17[/tex].

Applying Bhaskara:

[tex]\Delta = b^2 - 4ac = (-18)^2 - 4(1)(17) = 256[/tex]

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-(-18) + \sqrt{256}}{2} = 17[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{-(-18) - \sqrt{256}}{2} = 1[/tex]

The values are: x = 17, x = 1.

No explanation

Answer: 80 meters

Step-by-step explanation:

There are two ways you could do this.

1st way (my personal way of doing it): Add 25 + 15 + 25 + 15. Then subtract that by 9 + 7 + 9 + 7 (you do this because that will find the perimeter of the open space.)

=> 25 + 15 + 25 + 15 = 80

=> 9 + 7 + 9 + 7 = 32

=> 80 - 32 = 48

2nd way: Add 25, 15, 16 and 8. (You are adding the sides that they already give you.) Then, you would find the missing sides (or the sides that don’t have a number on the .) And that would be 7 and 9. So you add the sum of those two numbers to your answer.

=> 25 + 15 + 16 + 8 = 64

=> 7 + 9 = 16

=> 64 + 16 = 80

Answer:

In t years after 2019 there are going to be 39,523,462*(1.172)^t people.

Step-by-step explanation:

For a) We have a starting amount of 39,523,462 people in 2019, if each year it  grows at a rate if 1.72% then 1 year after 2019 would have 39,523,462*1.172 people. In 2 years we would have 39,523,462*1.172*1.172 or 39,523,462*1.172^2 people etc. We could conclude that after t years there would be 39,523,462*1.172^t people. In part b) just calculate this when t=11 and round this to the nearest whole number, I think you can do it yourself.
