Answer:
The rate at which the population decrease is 59.8 %
Step-by-step explanation:
Given as :
The population of city = 30,31,000
Now The population of city decrease to 22,46,000
The time period in which population decrease is 50 years
Let the percentage rate of decrease = R%
So,
Final population = initial population ×
Or, 22,46,000 = 30,31,000 ×
Or, =
Or, =
=
So , 0.99402 =
Or, = 1 - 0.99402
So, Rate = × 100
Or, Rate = 0.598 = 59.8 %
Hence The rate at which the population decrease is 59.8 % Answer

Rounding to the nearest tenth is one over to the right. If the number after it is greater than five then you make the number 1 higher if it is lower than five the number stays the same
Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.

▹ Answer
<em>Her dad's swimsuit costs $65.</em>
▹ Step-by-Step Explanation
Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.
$170 - $35 = $135
Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:
$35* 2 = $70
We will now add Monica's cost and her moms' cost:
$35 + $70 = $105
To find Monica's dads' cost, we will subtract 105 from 170:
$170 - $105 = $65
Her dad's swimsuit costs $65.
Hope this helps!
