The area of the circle is 5ft*5ft*pi = 25pi sqft

We're supposed to use 3.14 for pi, so the circle is around 25*3.14 sqft = 78.5sq ft

Number of digits in range = 10

Hence, each digit could be = (1 - 10)

1st digit = 10

2nd digit = 10

3rd digit = 10

4th digit = 10

Total possible combination :

Answer:

y = 2x + 6

Step-by-step explanation:

slope-intercept form => y = mx + b

substitute two of the (x, y) into the equations: y = mx + b  to solve for m and b

=> 0 = -3m + b, 6 = 0m + b

6 = 0m + b => b = 6

substitute b = 6 into 0 = -3m + b to solve for m:

=> 0 = -3m + 6 => -3m = -6 => m = 2

plug in b = 6 and m = 2 into the equation y = mx + b:

=> y = 2x + 6

Answer is y= 2x+6 hope it helps:)

At the tasty bakery, cupcakes cost fifty cents each.Doughnuts cost a dollar twenty five.How much more do two doughnuts cost than two cupcakes?

Answers

Answer:

$1.50

Step-by-step explanation:

The computation is shown below:

Given that

The cost of each cupcakes be 0.50 cents

And, the cost of doughnuts be $25

So for two doughnuts the cost would be 2.50

And, for two cupcakes, the cost would be 0.50 × 2 = 1

So, the more amount would be

= 2.50 - 1

= $1.50

Hence, the same would be considered and relevant too

Triangle ABC has AB = 10 √3cm, AC=6cm and has area 45cm^2
(i) Find the size of angle CAB.

(ii) Find the length of BC

Answers

Answer:

I) ∠CAB measures 60°.

II) BC measures approximately 15.23 cm.

*Please read notes.

Step-by-step explanation:

We are given ΔABC, where AB measures 10√3 cm, AC measures 6 cm, and the triangle has an area of 45 square cm.

And we want to find I) the measure of ∠CAB and II) the length of BC.

I) First, we should always draw a representative triangle so we can determine the sides and angles. This is shown below.

Note that ∠CAB (or simply ∠A) is the angle between the two sides. Thus, we can find the angle by using the alternative formula for the area of a triangle:

[tex]\displaystyle A=\frac{1}{2}ab\sin(C)[/tex]

Where a and b are two side lengths, and C is the angle between the two sides.

Substitute:

[tex]\displaystyle 45=\frac{1}{2}(10\sqrt{3})(6)\sin(A)[/tex]

Simplify:

[tex]\displaystyle 45=30\sqrt{3}\sin(A)[/tex]

So:

[tex]\displaystyle \sin(A)=\frac{45}{30\sqrt{3}}=\frac{3}{2\sqrt3}=\frac{\sqrt{3}}{2}[/tex]

Take the inverse sine of both sides. Use a calculator. Thus:

[tex]\displaystyle m\angle A=\sin^{-1}\left(\frac{\sqrt{3}}{2}\right)=60^\circ[/tex]

II) To find BC, we will use the Law of Cosines. We do not know whether or not ΔABC is a right triangle, so we cannot use right triangle trigonometry or special right triangles.

The law of cosines is:

[tex]\displaystyle c^2=a^2+b^2-2ab\cos(C)[/tex]

Where a and b are side lengths and C is the angle between the side lengths. c is the side length opposite to the angle.

BC is opposite to A. Substitute:

[tex](BC)^2=(10\sqrt{3})^2+(6)^2-2(10\sqrt{3})(6)\cos(60^\circ)[/tex]

Simplify:

[tex]\displaystyle BC^2=336-120\sqrt{3}\left(\frac{1}{2}\right)=336-60\sqrt{3}[/tex]

Take the square root of both sides:

[tex]\displaystyle BC=\sqrt{336-60\sqrt{3}}\approx 15.23[/tex]

BC measures about 15.23 cm.

Notes:

In this case, the inverse sine of √3/2 will yield two answers: 60° and 120°. This is an example of an ambiguous case. Both of these angles will work. However, BC will be different. If ∠A is 60°, then BC is about 15.23. However, if ∠A is 120°, then BC is about 20.97. Both will result in the triangle having an area of 45 square cm, as well as AB measuring 10√3 and AC measuring 6.

Togo was a small, black and white husky who had spent most of his life pulling sleds. When he was a puppy, his owner, Leonhard Seppala, never thought he would be a good sled dog. Togo was smaller than most dogs on the team. He was ill when he was very young, and at six months old, he was given away to be a house pet. Togo did not last long as a pet. He escaped several times to return to the sled dog kennels. He ran after the team every day on their training runs, and eventually, he was given a chance to run in harness. He had found his purpose.Togo was a natural leader, and he was the dog Leonhard Seppala trusted the most. During the run from Nenana, he led his team through life-threatening situations. One night, when the darkness and snow made it impossible for Seppala to see where they were going, and they were in grave danger from the below-zero temperatures, Togo courageously led the team across a frozen lake, avoiding the broken areas of ice. He navigated to the rest stop, saving his team from freezing in the blizzard. Togo's team brought the medicine almost 200 miles, crossing a mountain with an elevation of more than 5,000 feet and swimming through ice floes on the other side. They reached their drop-off point and passed the medicine to the next team. After the drop-off, Togo rested for a while before taking off with some of the other dogs on his team to chase reindeer. It was like a small vacation after his hard work.What evidence does the author use to support the idea that Togo was a natural leader who led his team through life-threatening situations?
