Equation:
500-30x=130+20x
Since you want to find when they are the same, you put an equal sign. Also, since one is gaining and the other is losing, you have an addition and subtraction sign.
Solution:
370= 50x
x=7.4
Answer:
After 7.4 years, the clubs will have the same members, which is 278 members.

Sarah rolls a die twice. What is the probability that she rolls a 3 and then an even number?
Brrunno [24]

Answer:

A

Step-by-step explanation:

The probability of rolling a 3 is  

1 /6  since there is 1 three and there are 6 sides total. The probability of rolling an even number is  1 /2  since there are 3 even numbers and 6 total sides. Multiply  1 /6  and  1 /2  and the correct answer is  1 /12 .

The population of a type of local dragonfly can be found using an infinite geometric series where a1 = 65 and the common ratio i
hram777 [196]
In mathematics, number sequencing of the same pattern are called progression. There are three types of progression: arithmetic, harmonic and geometric. The pattern in arithmetic is called common difference, while the pattern in geometric is called common ratio. Harmonic progression is just the reciprocal of the arithmetic sequence.

The common ratio is denoted as r. For values of r<1, the sum of the infinite series is equal to

S∞ = A₁/(1-r), where A1 is the first term of the sequence. Substituting A₁=65 and r=1/6:

S∞ = A₁/(1-r) = 65/(1-1/6)
S∞ = 78

A painting contractor paints with a brush at a rate of 192 square feet per hour. using a paint sprayer, she is able to cover 576
lara31 [8.8K]

Hi there,

2400 + 1632 = 4032

3 * 192 = 576

4032 - 576 =>

3532 - 76 =>

3532 + 24 - 76 - 24

3556 - 100

3456


3456 / 576 => 6

Therefore, 6 hours of sprayer work

Hope this helps!

Sincerely,

Dus4nR
