R - Right Handed 
L - Left Handed 

R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids) 
9L + L = 30  ( since total number of people in class is 30) 
10L = 30 
( Divide by 10 both sides )
L = 3 

so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)

Hope this helped!

3.920 * (1.018)^x = 5.500<br><br>X=?​
Andrei [34K]

Answer:

19

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

  • First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
  • Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
  • We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
  • Then we can divide both sides by ln(1.108) to get: x=\frac{ln(1.403)}{ln(1.018)}
  • Then using a calculator we get x = 18.98 ≈19

Find the length of the median and the missing base. Be sure to show all your work. NO LINKS!!!​
dezoksy [38]

Answer:

The bottom is  11

The median is  12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12

If a household is saving 30% of their total bi-weekly gross pay of $2,051.00, determine how many months it will take to save a 2
Anna35 [415]

Based on the amount saved per week and the down payment of the property, the number of months it will take to save the amount is 46 months.

<h3>How long will it take for the family to save the amount?</h3>

First, find out the amount saved per month:

= (30% x 2,051) x 2 payments a month

= $1,230.60

The downpayment is:

= 281,700 x 20%

= $56,340

The closing cost is:

= 1.15 x 56,230

= $843.45

The number of months till the amount is saved is:

= (56,340 + 843.45) / 1,230.60

= 46 months
