Answer:

JL = 16sqrt(2) units or 22.627417 units

Step-by-step explanation:

A square has 4 equally long sides, making all the sides 16 units long.

For a square with side S, the length of the square's diagonal is D=S*sqrt(2), therefore the length of the diagonal is 16sqrt(2) units or 22.627417 units

Answer:

For increasing order: 6

For decreasing order:7

Step-by-step explanation:

Case (1):

When the four digits are the consecutive integers in increasing order, then the possible digits at the thousands place (digit 4) are 1,2,3,4,5, and 6.

The numbers formed are 1234, 2345, 3456, 4567, 5678, and 6789.

Therefore, there are 6 four-digit positive integers for increasing order of consecutive digit.

Note that 0 can't be placed at the thousands place to get a four-digit integer.

Case(2):

When the four digits are the consecutive integers in decreasing order, then the possible digits at the unit place (digit 1) are 0, 1,2,3,4,5, and 6.

The numbers formed are 3210, 4321, 5432, 6543, 7654, 8765, 9876.

Therefore, there are 7 four-digit positive integers for decreasing order of consecutive digit.

Write out the base-x expansion of [tex]101_x[/tex] :

[tex]101_x[/tex] = 1 • x² + 0 • x¹ + 1 • x⁰

This number is equal to 17 (in base 10), so that

x² + 1 = 17

Solve this for x :

x² = 16

x = ±4

(Yes, negative bases are totally valid.)

Answer:

Step-by-step explanation:

first note that 5/4 of a revolution comes out to (5/4)(2π) radians, or

5/8 radian.  Thus, the distance traveled by the point is

s = rФ, where r is the radius and Ф is the angle through which the blade rotates.  Here we have:

s = (224 ft)(5/4)π ft

Answer:

4, -3, -2, -1, 0, 1

Step-by-step explanation:

since there are 6 consecutive integers, we can say create an equation:

n + (n+1) + (n+2) + (n+3)+ (n+4) + (n+5) = -9

add like terms to get:

6n + 15 = -9

subtract 15 from both sides:

6n = -24

divide both sides by 6 and you get n:

n = -4

plug -4 into n + (n+1) + (n+2) + (n+3)+ (n+4) + (n+5) to find all six integers:

-4 + (-4 + 1) + (-4 + 2) + (-4 + 3)+ (-4 + 4) + (-4 + 5)

simplify the parenthesis:

-4, -3, -2, -1, 0, 1

the sum of all of these number are -9

Because 4 for$ 7 you not get as much if you did 5 for $8 so the answer would be 5 for $8

Answer:  m = 6/7n-1

Step-by-step explanation: to get 7m alone dirst we must subtract 2 from both sides so 2-2 = 0 and -5 - 2= -7 so 7m= 6n-7 and divide both sides by 7 to get m alone so 6n divided by 7 = 6/7n and -7 divided by 7 equals -1 so we're left with m= 6/7n-1

The formula for f(m) in terms of m is:

f(m) = (6m - 7) / 7

To write a formula for f(m) in terms of m, we need to isolate m on one side of the equation.

Given the equation 7m + 2 = 6n - 5, we can start by moving all terms involving m to one side and all terms involving n to the other side:

7m - 6n = -5 - 2

Simplifying:

7m - 6n = -7

Now, we can express m in terms of n:

7m = 6n - 7

Dividing both sides of the equation by 7:

m = (6n - 7) / 7

Thus, the formula for f(m) in terms of m is:

f(m) = (6m - 7) / 7

This formula allows us to calculate the value of f(m) based on the given relationship between m and n. By substituting different values of m into the formula, we can determine the corresponding values of f(m) for those inputs.

Step-by-step explanation:

Answer:

There would be $118,580 but to the nearest hundred there would be $118,600.

Step-by-step explanation:

The answer is 118,600 because 4.5% of 77,000 is 3465 and 3465 multiplied by 12 is 41580 and 77,000 plus 41580 is 118,580 but rounded to the nearest hundred it would be 118,600.

Answer:

80 km

Step-by-step explanation:

First, find the perimeter of the park.

2(12 + 8) = 2(20) = 40 km

Since Rama travels around the park twice, multiply the perimeter by 2.

40(2) = 80 km

9514 1404 393

Answer:

  80 km

Step-by-step explanation:

The perimeter is twice the sum of length and breadth:

  P = 2(length +breadth)

  P = 2(8 km +12 km) = 40 km

Twice around is then ...

  2 × 40 km = 80 km . . . . distance traveled by Rama

Answer:

4 hours

Step-by-step explanation:

Given that:

Initial height of red candle = 8 inches

Rate of burning of red candle = [tex]\frac{7}{10}\ inch/hr[/tex]

Initial height of blue candle = 6 inches

Rate of burning of blue candle = [tex]\frac{1}{5}\ inch/hr[/tex]

To find:

Time taken in hours such that both the candles have the same height.

Solution:

Let the time taken such that both the candles have the same height = [tex]t[/tex] hours

Height of red candle after [tex]t[/tex] hours = [tex](8 - \frac{7}{10}t) \ inches[/tex]

Height of blue candle after [tex]t[/tex] hours = [tex](6 - \frac{1}{5}t) \ inches[/tex]

Writing both the expressions as equal:

[tex]8-\dfrac{7}{10}t=6-\dfrac{1}{5}t\\\Rightarrow 8-6=\dfrac{7}{10}-\dfrac{1}{5}t\\\Rightarrow 2 = (\dfrac{7-2}{10})t\\\Rightarrow \dfrac{5t}{10}=2\\\Rightarrow t=4\ hours[/tex]

After 4 hours, height of both the candles will be same.

Answer:

1.625 miles

Step-by-step explanation:

40 miles in 65 minutes means that every 65 minutes, 40 miles is travelled. To find the distance travelled per minute, divide 65 and 40:

65 minutes / 40 miles = 1.625 miles per minute. So every minute, the train travels 1.625 miles.
