Step-by-step explanation:

Set up the equation 1331/x=x^2/1331

Cross multiply and simplify the answer.

Answer:

[tex]\sqrt{149\\ \\[/tex]

However, that's the length of "c" and you're looking to drag it in. So,o you drag in 10^2+7^2=a^2.

Then, as shown by the first picture attatched, you can drag in the one with "c" and "a" with the five shown.

Step-by-step explanation:

To find "c" the diagonal, as explained, you need to use the theorem twice. You can first use it by finding "a", as you already have "b". To find a, you do 10^2+7^2=a^2, the hypotenuse.

100+49=149.

So, a is root 149.

a^2+b^2=c^2 so

149+25=174

a) The length of a, a² = 10² + 7²

b) The fourth Figure will be Drag in Last column.

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

As From the Figure, a² = 10² + 7²

a² = 100 + 49

a² = 149

a= √149

To find c the diagonal,

a² = 10²+ 7²

a² = 149

a = √149

Now, a²+b²=c²

The fourth Figure will be Drag in Last column.

Answer:

s = 28/9

Step-by-step explanation:

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9

The average speed is 28/9.

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

Example

Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.

To find the average speed we need the total distance and the total time.

Total distance covered by Sam = 200Km + 160 km = 360 km

Total time taken by Sam = 4 hour + 4 hour = 8 hour

Average Speed = Total distance covered ÷ Total time taken

Average Speed = 360 ÷ 8 = 45km/hr

The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:

Average Speed Formula:

Average Speed = Total distance covered ÷ Total time taken

Given:

halfway at 2mph and runs the rest of the way at 7mph

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9 mph

Your answer would be that 1.2 is bigger.

This is the case because the tenths place, the decimal farthest to the left, is greater than the compared tenths place, which has a 1

1 is greater than 2

With that information, 1.2 is bigger.

Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).

To compare 1.2 and 1.18 repeating (1.181818...), we can first convert 1.18 repeating to a fraction.

Let x = 1.181818...

Now, multiply x by 100 to remove the repeating decimal:

100x = 118.181818...

Subtract x from 100x to eliminate the repeating part:

100x - x = 118.181818... - 1.181818...

99x = 117

x = 117 / 99

Now, we simplify the fraction:

x = 13 / 11

Now that we have both numbers in decimal form, we can compare them:

1.2 ≈ 1.2 (rounded to one decimal place)

1.18 repeating = 13 / 11 ≈ 1.1818 (rounded to four decimal places)

Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).

Step-by-step explanation:

As shown, you add four by each.

4+4=8

8+4=12

So, 12+4=16

16+4=20

Answer:

16 and 20

Step-by-step explanation:

In the arithmetic squence, we can tell that 4 is being added to each term.

Thus, we obtain the following rule:

To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.

Determining the 4th term of the sequence:

⇒ 4x

⇒ 4(4)

⇒ 16

Determining the 5th term of the sequence:

⇒ 4x

⇒ 4(5)

⇒ 20

Thus, the next two terms are 16 and 20.

125, 100, 80,64,51.2,40.96...

Step-by-step explanation:

y=[tex]\frac{4}{5}[/tex]x

So let's work backwards!

[tex]\frac{5}{4}[/tex](80)

=100

Then...

[tex]\frac{5}{4}[/tex](100)

=125

Hope this helps! :D

Answer:

  125, 100

Step-by-step explanation:

Perhaps the terms of your series are supposed to be ...

  __, __, 80, 64, 51.2, 40.96, ...

The common ratio is 64/80 = 0.8, so the recursive relation is ...

  t[n] = 0.8×t[n-1]

__

Solving for the previous term, we find ...

  t[n]/0.8 = t[n-1] . . . . . . divide by 0.8

or ...

  t[n-1] = 1.25×t[n] . . . . . rearrange

Then the term previous to 80 is 1.25×80 = 100.

And the term previous to 100 is 1.25×100 = 125.

The first two terms of the geometric sequence are 125 and 100.

Answer:

C.

Step-by-step explanation:

When we add up all the numbers we get 111 then we divide it by 10 which gives us 11.1. since we have no value to round to the tenths place, the answer stays the same.

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb

Answer:

The values that are in the correct spots are: 82, 62, 163 and 300

Step-by-step explanation:

There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.

82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.

62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.

156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.
