Answer:

(-6, -4)

Step-by-step explanation:

Original coordinates: (6, -4)

POINT S IS 12 UNITS TO THE LEFT OF POINT P.

There are multiple ways to solve this, but I will explain the easiest way.

We can subtract 12 from the x-coordinate.

This because the x-axis runs RIGHT and LEFT.

The y-axis runs UP and DOWN.

6 - 12 = -6

The y-coordinate stays the same.

The new coordinates are: (-6, -4).

Answer:

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

Step-by-step explanation:

The data given is

               Today               Five Years Ago

X`                 81                           85

σ              14.5                        8.5

n                81                          36

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

The test statistics that will be used is

Z= x1-x2/ √σ₁²/ n₁ + σ₂²/n₂

Z=  81- 85/ √14.5² /81 + 8.5² /36

z= -4/√210.25/81+ 72.25/36

z= -4/2.1454

z= -1.8644

Answer:

You can make 27 different 3 digit numbers

Step-by-step explanation:

Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.

3 x 3 x 3 = 27

I'll do problems 13 and 14 to get you started.

=====================================================

Problem 13

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

Explanation:

Refer to the diagram below for problem 13. Since BD is a tangent of the circle, this means angle ABD is 90 degrees, and furthermore x+y = 90. This solves to y = 90-x.

If we focus on triangle ABC, then we can add the interior angles and set the sum equal to 180

A+B+C = 180

z+y+y = 180

z+2y = 180

z+2(90-x) = 180 .... plug in y = 90-x

z+180-2x = 180

z-2x = 180-180

z-2x = 0

z = 2x

We'll use this later.

Now move onto triangle ABD. This is a right triangle due to angle ABD being 90 degrees. The acute angles z and 26 are complementary, meaning they add to 90. So,

z+26 = 90

z = 90-26

z = 64

Now plug this into z = 2x and solve for x

z = 2x

64 = 2x

2x = 64

x = 64/2

x = 32

=====================================================

Problem 14

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

Explanation:

Refer to the image shown below for problem 14. Like before, I've added various labels to it to help find the angle we're after (the red angle x).

Note how I've drawn a dashed line from point A to point D. This splits up quadrilateral ABCD into two triangles ABD and ACD. These triangles can be shown to be congruent using the HL (hypotenuse leg) theorem.

The congruent triangles also implies that angle DBC and angle BCD are the same measure (both are shown in green as the variable y).

Focus on triangle BCD. It has interior angles of: y, y and 62. Add them up, set the sum equal to 180.

y+y+62 = 180

2y+62 = 180

2y = 180-62

2y = 118

y = 118/2

y = 59

As the image attachment mentions, the angles x and y add to 90 degrees. This is because angle ABD is 90 degrees, due to segment BD being tangent to the circle. So x+y = 90 leads to x = 90-y, and therefore,

x = 90-y

x = 90-59

x = 31

Side note: it is not a coincidence that we ended up with half of the value of 62.

Answer:

The surface area is 177 square inches

Step-by-step explanation:

Given

[tex]Length = 10[/tex]

[tex]Width = 3[/tex]

[tex]Height = 4\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

So, we have:

[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]

[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]

[tex]Area = 2 * (88\frac{1}{2})[/tex]

[tex]Area = 177[/tex]

Answer:

1920 cm³

Step-by-step explanation:

V = w · h · l

V = 8 · 14 · 10

V = 1120 cm³

Now for the smaller one.

V = w · h · l

V = 8 · 10 · 10

V = 800 cm³

1120 cm³ + 800 cm³

1920 cm³

Answer:

1920 cm ^3

Step-by-step explanation:

find the volume of the 2 cuboids seperatly.

bigger one: LXWXH --> 8 X 14 X 10 = 1120

smaller one: LXWXH --> 10X10X8 = 800

add them up

1120 + 800 = 1920 cm

Hope this helps :D

Answer:32,200

Step-by-step explanation:

8% is 2576, a simple way to solve for this is to find 1% and that would be 322, then multiply by 100 and you get the total number of people attended, this is not the best method but works in this situation with whole numbers.

Number of people attended the game = 32200

A percentage is a number or ratio that can be expressed as a fraction of 100. If we need to calculate a percentage of a number, divide that number by the whole number and multiply by 100. Percentages therefore mean fractions of 100.  

Given,

Total number of supporter = 2576

Percentage of supporters = 8%

Let total number of attendees = x

the,

8% of x = 2576

8x/100 = 2576

8x = 257600

x = 257600/8

x = 32200

Hence, 32200 people attended the game.

Answer:

what is the question?

Step-by-step explanation:

Answer:

2.46212121 miles

-

convert a mile measurement to a foot measurement, multiply the length by the conversion ratio. The length in feet is equal to the miles multiplied by 5,280

The mile, sometimes the international mile to distinguish it from other miles, is the British imperial unit and the US customary unit, both systems are based on the older English unit of length equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959

To convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

To convert a distance of 13,000 feet to miles, you can multiply it by the conversion factor of 1 mile divided by 5,280 feet.

We know that

1 mile= 5280 feet

Then we will use the ratio of 1 mile / 5,280 feet, the numerator 1 represents the equivalent distance in miles, and the denominator 5,280 represents the equivalent distance in feet.

So, 13000 feet x 1 mile/ 5280 feet

= 13000/ 5280

= 2.462121212121212 miles

Therefore, to convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

8- The volume of a cone is:

Let's substitute the values and solve:

If you want to round it, the answer will be:

9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.

So,

10- The volume of the cone is V = hπr² / 3

Then,

9 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.

Answer:

1.6875

Step-by-step explanation:

Volume of a pyramid = 1/3 (l*w*h)

Volume = 1/3(6 * 6 * 9)

Volume = 2 * 6 * 9

Volume = 108 cm³

Volume of cube = s³ ; s = side length

Volume = 4³ = 4 * 4 * 4 = 64 cm³

Number of wax cube = Volume of pyramid / volume of cube

= 108 cm³ / 64 cm³

= 1.6875
