Answer:

3679 miles

Step-by-step explanation:

Total distance covered = 5882 miles

Distance covered on first trip = 2203 miles

Distance flown on second trip = total distance covered - distance covered on first trip

Distance flown on second trip = (5882 - 2203) miles = 3679 miles

Answer:

Step-by-step explanation:

Equation for a circle of radius r, centered at (h,k):

(x-h)² + (y-k)² = r²

x² + (y+3)² = 9 is the equation for a circle of radius 3, centered at (0,-3).

Option D - Coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair IS CORRECT.

We have a equation of circle -

[tex]x^{2} +(y+3)^{2} = 9[/tex]

We have to find out which statement correctly represents the graph of this equation.

The general equation of the circle with radius r and center at (h, k)

is -  [tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]

The equation given to us is -

[tex]x^{2} +(y+3)^{2} = 9[/tex]

On comparing it with the general equation of the circle, we get -

[tex]x-h=x\\h=0\\\\y-k=y+3\\k=-3\\\\r^{2} =9\\r=3[/tex]

Therefore, we have a circle whose center lies at (0, -3) with radius = 3 units.

At point P(3, 3) -

[tex](-3)^{2}+(-3+3)^{2} =9\\9=9[/tex]

Hence, Option D - coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair is correct.

Answer:

r = 9 units

Step-by-step explanation:

[tex] In\: \odot O, [/tex] QP is tangent at point P and OP is radius.

[tex] \therefore OP\perp QP[/tex]

[tex] \therefore m\angle OPQ = 90\degree [/tex]

So, [tex] \triangle OPQ[/tex] is a right angled triangle. Hence, OQ will be its HYPOTENUSE such that OQ = r + 32

Now, by Pythagoras theorem:

[tex] OQ^2 = OP^2 + PQ^2 [/tex]

[tex] \therefore (r + 32)^2 = r^2 + (40)^2 [/tex]

[tex] \therefore\cancel {r^2} + 64r + 1024 = \cancel {r^2} + 1600 [/tex]

[tex] \therefore 64r = 1600-1024 [/tex]

[tex] \therefore 64r = 576 [/tex]

[tex] \therefore r = \frac{576}{64}[/tex]

[tex] \therefore r = 9[/tex]

Answer: B, Parallelogram, and rectangle

Step-by-step explanation:

A parallelogram requires two parallel sides which that shape has.

A rectangle requires all angles to be right angles and that shape has all angles being right angles.

The shape is not a rhombus since all sides are not the same and it's not a square for the same reason.

Answer:

C

Step-by-step explanation:

Looking at the first point we know that it can't be A

Then we can easily see that the rate of change is not level (which means it isn't linear)

this leaves option C

Another way to solve this is just by plugging in points

for example for C

Answer:

Bob's can make one burger in 0.3 minutes, or 18 seconds.

Step-by-step explanation:

Bob's can make 10 hamburgers in 3 minutes. To determine how long it takes Bob's to make a single hamburger, we divide the 3 minutes by the 10 hamburgers.

3/10 = 0.3 minutes

It takes him 0.3 minutes to make one burger.

We could go further and convert this time to seconds. To do this, we multiply 0.3 minutes by 60 seconds.

0.3 ⋅ 60 = 18 seconds

Bob's can make one hamburger in 18 seconds.

Answer: 80% or 4/5

Step-by-step explanation:

so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.

10 numbers

10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)

so 8/10 or 80%

reduced fraction: 4/5

percentage: 80%

fraction: 8/10

Menjawab:

1000

Penjelasan langkah demi langkah:

Mengingat bahwa :

Harga palu 10 potong harga paku;

Harga selusin paku = 1200

1 lusin = 12

Jadi harga paku adalah:

1200/12

= 100

Makanya, harga paku = 100

Jadi, harga palu adalah:

10 kali lipat, harga paku

10 * 100 = 1000

Answer:

26.1 feet

Step-by-step explanation:

This question is solved using Pythagoras theorem

Pythagoras Theorem =

c² = a² + b²

c = longest side = 27 feet

One post is 12 feet tall while the other is 19 feet tall.

The vertical side = a is calculated as

19 - 12 = 7 feet.

The third side = b = how far apart they are = ?

Therefore,

27² = 7² + b²

b² = 27² - 7²

b = √27² - 7²

b = √(680)

b = 26.076809621 feet

Approximately = 26.1 feet

Therefore, the distance between the posts = 26.1 feet

Answer:

C: 22 points.

Step-by-step explanation:

Given:

The data set is:

14, 15, 3, 15, 14, 14, 18, 15, 8, 16

To find:

The mean, median and mode of the given data set.

Solution:

We have,

14, 15, 3, 15, 14, 14, 18, 15, 8, 16

Arrange the data values in ascending order.

3, 8, 14, 14, 14, 15, 15, 15, 16, 18

Mean of the data set is:

[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observation}}[/tex]

[tex]Mean=\dfrac{3+8+14+14+14+15+15+15+16+18}{10}[/tex]

[tex]Mean=\dfrac{132}{10}[/tex]

[tex]Mean=13.2[/tex]

The number of observation is 10 which is an even number. So, the median of the data set is:

[tex]Median=\dfrac{(\dfrac{n}{2})\text{th term}+(\dfrac{n}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{(\dfrac{10}{2})\text{th term}+(\dfrac{10}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{5\text{th term}+6\text{th term}}{2}[/tex]

[tex]Median=\dfrac{14+15}{2}[/tex]

[tex]Median=\dfrac{29}{2}[/tex]

[tex]Median=14.5[/tex]

Mode is the most frequent value of the data set.

In the given data set the highest frequency is 3 because 14 and 15 occurs three times.

So, the mode of the given data set is 14 and`15.

Therefore, the mean is 13.2, median is 14.5 and mode is 14 and 15.

Answer:

$223.21

Step-by-step explanation:

Last year the amount of taxes was x, an unknown amount. That was 100% of last year's tax cost.

This year, taxes went up by 12%, so this year the taxes are 112% of what they were last year. This year the taxes were 112% of x, and they were $250.

112% of x = 250

1.12x = 250

x = 250/1.12

x = 223.21
