In rectangle KLMN, KM=6x+16 and LN =49 find the value of x

Answers

Answer 1

Answer: 6x+16=49
6x=49-16
6x=33
x=33/6
x=5.5

Answer 2

Answer: Diagonals bisect each other meaning you would set LN and KM equal to each other.
6x+16=49
-16 -16
6x=33
x=5.5

Bryan plays on the high school basketball team. In his first ten games he scored 12, 14, 8, 9, 8, 16, 8, 13, 22, and 19 points. Choose and calculate the best measure of central tendency to represent Bryan's scoring over the first ten games. Justify your choice.

Answers

The best tendency is the "middle" or "most common" value, so basically it's either the mean or the mode- in this case we use the mode and we can see 12,14,8,9,8, 13, 22 ,19 so 8,8,9,12,13,14,18,22 ; the answer is 13

If there were 300 accidents in 1967 and 380 in 1968, what is the percent increase?

Answers

Answer:

As per the statement:

If there were 300 accidents in 1967 and 380 in 1968.

Number of accident in 1967= 300

Number of accident in 1968= 380

then;

Increase in accident = 380-300 = 80

Using formula to find the percent increase:

$\text{Increase in percent} = \frac{\text{Increase in accident}}{\text{Number of accident in 1967}} * 100$

Substitute the given values we have;

$\text{Increase in percent} = (80)/(300) * 100$

Simplify:

$\text{Increase in percent} = (80)/(3) = 26(2)/(3) \%$

Therefore, $26(2)/(3) \%$ is the percent increase

First find the amount of increase: 380-300=80. Then divide the amount of increase by the original amount: 80/300=.266666667. Normally you round to the tenths place: .27. Then make it a percent: .27=27%. The percent of increase is 27% :) hope this helps

A car traveling at a constant speed for 150km in 7200s, what is its speed?

Answers

75 km/hr, so in other words 75 km per hour.

How do you do this problem?
Solve by factoring or finding square roots.
x^2-1=0

Answers

use formula^: a²-b²= (a-b)(a+b)
x²-1=0
x²-1²=0
(x-1)(x+1)=0
x-1=0⇒ x₁=-1
x+1=0 ⇒x₂=1
Answer: x=+-1

x² - 1 = 0
   + 1 + 1
      x² = 1
   x = +1
