Area of a circle is equal to [tex]\boldsymbol{132.8}[/tex] square inches.

A circle is a collection of all the points that are at the fixed distance (radius) from a fixed point (center).

Diameter of a circle [tex]=\boldsymbol{13}[/tex] centimeter

Radius of a circle is half of the diameter.

So,

Radius of a circle [tex]=\frac{13}{2}[/tex] centimeter

Area of a circle [tex]=\boldsymbol{\pi r^2}[/tex] where [tex]r[/tex] denotes radius of a circle.

                         [tex]=\frac{22}{7}\times \left ( \frac{13}{2} \right )^{2}\\=132.7857[/tex]

                         [tex]\boldsymbol{\approx 132.8}[/tex] square inches

So, area of a circle is equal to [tex]\boldsymbol{132.8}[/tex] square inches.

Answer:

the Answer is the 1,3,and 4

Step-by-step explanation:

Let the first part be x. Then,

the second part will be (10000-x).

So, According to question,

(10% of x) + { 7% of (10000-x)} = 805

(10/100*x) +{7/100*(10000-x)} = 805

(x/10) + (70000-7x/100) = 805

Then,

We will take the lcm of 10 and 100 which is 100 and then add both the fractions.

Solution:

10x + 70000-7x/ 100 = 805

3x + 70000/100 = 805

3x + 70000 = 805*100

3x + 70000 = 80500

3x = 80500-70000

3x = 10500

x = 10500/3

x = 3500

So the first part is 3500.Then,

the second part will be (10000-3500)

= 6500

Answer: 49 degrees

Step-by-step explanation:

Answer:

1) From Columbus to San Juan, Sam flies 2,028 miles

2)Sam will have 460 miles more miles to fly to Kralendijk  

Step-by-step explanation:

The given information are;

The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire = 2,488 miles

The distance Sam flies from Columbus to Miami, Florida = 995 miles

The distance Sam flies from Miami to San Juan = 1,033 miles

1) Therefore, the number of miles Sam travels flying from Columbus to San Juan is given as follows;

The number of miles Sam will have to travel flying from Columbus to San Juan = (The distance Sam flies from Columbus to Miami, Florida) + (The distance Sam flies from Miami to San Juan)

The number of miles Sam will have to travel flying from Columbus to San Juan = 995 miles +  1,033 miles = 2028 miles

The number of miles Sam will have to travel flying from Columbus to San Juan = 2,028 miles

Therefore, from Columbus to San Juan, Sam flies 2,028 miles

2) The number of more miles Sam has to fly to Kralendijk from Sam Juan is therefore;

The number of more miles Sam has to fly to Kralendijk from Sam Juan = (The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire) - (The number of miles Sam will have to travel flying from Columbus to San Juan)

The number of more miles Sam has to fly to Kralendijk from Sam Juan = 2,488 miles  - 2,028 miles = 460 miles.

The number of more miles Sam has to fly to Kralendijk from Sam Juan = 460 miles.

Therefore, Sam will have 460 miles more miles to fly to Kralendijk  

From the division of the trip into parts, it is found that:

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

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

Since Columbus to Miami is 995 miles and Miami to San Juan is 1033 miles, we have that the distance from Columbus to San Juan, in miles, is of:

[tex]995 + 1033 = 2028[/tex]

Thus:

From Columbus to San Juan, Sam flies 2028 miles.

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

[tex]2028 + x = 2488[/tex]

[tex]x = 2488 - 2028[/tex]

[tex]x = 460[/tex]

Thus:

He will have more 460 miles to fly.

Answer:

708480

Step-by-step explanation:

You follow the order of BEDMAS. There are brackets in this equation, meaning we have to focus on what is inside the brackets first. The next step is Exponents. So you multiply 2.05 by 10^5.

This would give you 205000.

You then multiply this number by the number on the outside of the brackets which is 3.456.

This would give you 708480. (You can get these answers by using a calculator).

Don't forgot to follow the order of BEDMAS or whatever law of operations you were taught (BIDMAS/BIMDAS etc)

Hope this helps :)

There are 24 hours in a day and so 15 hours is 15÷24=58 of a day. Since the rig drills 60 feet underground in a day, in 58 of a day it will drill

(58 days)×(60feetday)=3008 feet.

So the rig will have drilled 3008=37.5 feet underground in 15 hours.

The rig drills 60 feet underground per day so to find how long it has been running to go 143.6 feet underground, we need to calculate

(143.6 feet)÷(60feetday)=143.660 days.

This is about 2.4 days. Alternatively, it is 57.44 hours

We know that the rig drills at a constant rate, so there is a proportional relationship between the two quantities d, the height to which the drill has dug, and t, the number of days the drill runs. It drills at -60 feet per day, so we can represent this relationship with the equation:

–60t=d

Since 15 hours is 1524=58 days, we can use the equation to find d:  

–60⋅58=d

Since the depth is the same whether we think of it as a positive depth below the surface or a negative height above the surface, we can find this value by multiplying 60⋅58=37.5  and then noting that the sign must be negative if we are representing positions below the surface of the earth by negative numbers. So d=–37.5 and the drill will be at height -37.5 feet after 15 hours.

Likewise, if we know the drill has dug to -143.6 feet, we can use the equation again, this time to find t:  

−60t=−143.6

so t=(−143.6)÷(−60). Since the amount of time would be the same if we were working with positive feet below the surface of the earth and a drill rate of 60 feet per day below the earth surface, we can find this value by dividing 143.6÷60, which is about 2.4 days.

Answer:

The mean increased, but the median stayed the same

Step-by-step explanation:

hope it help luvs

The mean increased, but the median remained constant If new dogs' weights are added to the data set.

The mean of a data set is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

The formula for the mean of a given set of data is as follows:

Mean = Sum of Observations/Total number of observations

Given the set of observations as :

16, 34, 44, 20, 50, 19, 30, 54

Arrange the data in ascending order, we get

16, 19, 20, 30, 34, 44, 50, 54

The median of the given data would be (30+34)/2 = 32.

Here, n = 8

⇒ ∑x = Sum of Observations

⇒ ∑x = 267

Mean = ∑x/n

Mean = 267/8

Mean = 33.375

If two more dogs weighing 25 pounds and 45 pounds come to the kennel.

Arrange the given data in ascending order, we get

16, 19, 20, 25, 30, 34, 44, 45, 50, 54

The new median of the data would be (30+34)/2 = 32.

New mean = 337/10 = 33.7

Therefore, the mean increased, but the median remained constant If new dogs' weights are added to the data set.

Answer:

[tex]y=8[/tex]

[tex]RS=77, ST=31[/tex]

Step-by-step explanation:

Note that the entire segment RT is the combined lengths of RS and ST. So:

[tex]RT=RS+ST[/tex]

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

[tex]108=(9y+5)+(3y+7)[/tex]

On the right, combine like terms:

[tex]108=(9y+3y)+(5+7)[/tex]

Add:

[tex]108=12y+12[/tex]

Subtract 12 from both sides. The right cancels:

[tex]96=12y[/tex]

Divide both sides by 12:

[tex]y=8[/tex]

So, the value of y is 8.

To find RS and ST, substitute 8 for y. So:

[tex]RS=9y+5[/tex]

Substitute 8 for y:

[tex]RS=9(8)+5[/tex]

Multiply:

[tex]RS=72+5[/tex]

Add:

[tex]RS=77[/tex]

Do the same for ST:

[tex]ST=3y+7[/tex]

Substitute 8 for y:

[tex]ST=3(8)+7[/tex]

Multiply:

[tex]ST=24+7[/tex]

Add:
