An athlete ran 10 times around the circular track shown below. Approximately how many meters did the athlete run?

Answers

Answer:

Step-by-step explanation:

Since the picture isn't given. I have no idea what the radius or diameter is and as such, have no definite answer for you.

However, from the question, if he's to run round the circular track once, then he must have run a total of

2πr meters, with r being the radius.

Now, the question says that he ran round the track 10 times, this means that whatever value we get there, for 1 trial, we multiply it by 10, to get the value for 10 trials. Essentially,

10 * 2πr

The value gotten is the needed answer. All you have to do is substitute r for the value you have in your diagram. We already know that π is 3.142

In a geometric sequence, the first term is 3 and the common ratio is 2. What is the sum of the first 9 terms?
a .99
b. 1022
c. 1533
d. 765

Answers

Step-by-step explanation:

99 is the answer........

The sum of the first 9 terms of the given GP series will be 1533 thus option (c ) is correct.

What is geometrical progression series?

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

Let's say the first term of the given GP is a and the common ratio is r.

a = 3 and r = 2

The Sum of n term is given as,

S = a([tex]r^{n}[/tex] - 1) / (r - 1)

S₉ = [3(2⁹ - 1)/(2 - 1)]

S₉ = 1533

Hence "The sum of the first 9 terms of the given GP series will be 1533".

3. In a thunderstorm, the wind velocity in meters per second can be described by the function

v(p)=5.7998−p‾‾‾‾‾‾‾√,

where

p

is the air pressure in millibars. What is the air pressure of a thunderstorm in which the wind velocity is 49.3 meters per second? Round your answer to the nearest tenth of a millibar.

Answers

Answer:

p = 923.2 millibar

Step-by-step explanation:

Given that,

The wind velocity can be described by the function as follows :

[tex]v(p)=5.7\sqrt{998-p}[/tex]

Where

p is the air pressure in millibar

Put v = 49.3 m/s in the above function.

[tex]49.3=5.7\sqrt{998-p}[/tex]

Squaring both sides,

[tex]49.3^2=(5.7\sqrt{998-p})^2\\\\2430.49=32.49(998-p)\\\\\dfrac{2430.49}{32.49}=(998-p)\\\\74.80=(998-p)\\\\p=998-74.80\\\\p=923.2\ mbar[/tex]

So, the required pressure is equal to 923.2 millibar.

Answer:

∡ a = 80°

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

a + 30 + 70 = 180

a + 100 = 180

a = 80

Answer:

80 Degrees

Step-by-step explanation:

A triangle equals 180 degrees when all sides are added together, so here we need to first add the angles of the ones we have available.

30 + 70 = 100

Now, we subtract to find out how much more we need...

180 - 100 = 80

1. find 15% of 120
2. what percent of 72 is 68.4
3. 12.5 is 8% of what number?
4. 48 is 40% of what number
5. what number is 62.5% of 195

Answers

For question 1:
1% = 120 ÷ 100 = 1.2
15% = 1.2 × 15 = 18
So, 15% of 120 is 18

For question 2:
68.4 ÷ 72 = 0.95
0.95 × 100 = 95%
So, the percentage is 95%

For question 3,
1% = 12.5 ÷ 8 = 1.5625
100% = 1.5625 × 100 = 156.25
So, 8% of 12.5 is 156.25.

For question 4,
1% = 48 ÷ 40 = 1.2
100% = 1.2 × 100 = 120
So, 40% of 48 is 120.

For question 5,
1% = 195 ÷ 100 = 1.95
62.5% = 1.95 × 62.5 = 121.875
So, 62.5% of 195 is 121.875

Answer:

1.  18        3. 52       5. 95%

Step-by-step explanation:

1. 120 x 0.15= 18.00 (15% of 120 is 18)

3. 84 x 0.03= 2.52

5. 72• x / 72 = 68.4/ 72

x=0.95 ⇒ 95%

Find the distance between the two points rounding to the nearest tenth
(if necessary).
(-7, -6) and (-3,2)
Submit Answer
Answer:

Answers

Answer:

8.9

Step-by-step explanation:

To solve this problem you just use the distance equation which is √((x1-x2)^2+(y1-y2)^2). It does not matter which point you use where but if you use -7 as your x1, you have to use -6 as your x1.

The process should look like this

√(-7-(-3))^2+(-6-2)^2)

√((-4)^2+(-8)^2)

√(16+64)

√(80)

=8.944 or 8.9 rounded to the nearest tenth

Convert the equation below to slope-intercept form
6x+ 8y = -32​

Answers

Answer:

y = -3/4x - 4

Step-by-step explanation:

Convert the equation to slope intercept form by isolating y

6x + 8y = -32​

Subtract 6x from both sides

8y = -6x - 32

Divide each side by 8

y = -6/8x - 4

Simplify -6/8 to -3/4

y = -3/4x - 4

So, the equation in slope intercept form is y = -3/4x - 4

He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States. The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict.Read the passage from the website: www.expandingcountries.edu/unitedstates/louisianapurchaseThe Louisiana Purchase doubled the size of the United States and vastly increased its resources and riches. The roles of the president and the Constitution were also defined, as it was determined that the president could purchase the land without consulting Congress. Despite the advantages of expanding westward, one prominent disadvantage was the growing tension between slave states and free states regarding whether new states would permit slavery. The opportunity to grow a nation would endanger its very survival during the Civil War.Which of the following text based responses correctly answers the following question: How did the Louisiana purchase benefit the United States? Use both texts to find the best response. aPioneers began to farm the new land or use other natural resources. Some of these people used the Mississippi River and the Port of New Orleans to ship their products. This purchase clarified the Constitution, increased riches, and led to buying more land. bPresident Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land.
