It did not rain on 12 out of the 30 days in April, which means it was rain-free 40% of the time.
The student asked, "It rained 18 days during April, what percentage of days did it not rain during April?" To calculate the percentage of days it did not rain, first determine the total number of days in April, which is 30. Then subtract the number of days it rained (18) from the total number of days to find the number of days it did not rain:
30 days (total in April) - 18 days (rain) = 12 days (no rain)
Next, divide the number of days it did not rain by the total number of days in the month and multiply by 100 to get the percentage:
(12 days no rain / 30 days total) * 100 = 40%
Therefore, it did not rain 40% of the time during April.

7(y-8)=7y+42 how many solutions does the following equations have
The equation 7(y-8)=7y+42 results in an implausible mathematical statement, meaning it has no valid solutions.
Explanation:To begin, we isolate variable y in the given equation 7(y-8)=7y+42. First, expand the product on the left-hand side, which will be 7y - 56. This provides the simplified form 7y - 56 = 7y + 42. From this equation, we realize that this is an equation that has no solutions because it results in an implausible statement: -56 is not equal to 42. If we try to solve such an equation, we reduce it to a statement that does not hold true in mathematics, leaving us with no valid solutions for variable y. Therefore, this equation has no solutions.

What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Nina paid the bill for dinner with her family.
The total cost of the food was $65, and the restaurant added an 8 percent sales tax, $5.20, to the bill.
Then the amount of the bill will be
Bill = Cost of food + Sales tax
Bill = 65 + 5.2
Bill = $70.2
Nina wants to pay a 15 percent tip on the total bill including sales tax.
The amount of the tip of the total bill will be
Tip amount = 15% x $70.5
Tip amount = 0.15 x $70.5
Tip amount = $10.53
The amount of the tip of the total bill will be $10.53.
Then the correct option is C.

A 2- liter bottle of water has a mass of 2 kilograms. How many grams is that?
To convert the mass of a 2-liter bottle of water from kilograms to grams, multiply 2 kg by 1000, resulting in 2000 grams.
A 2-liter bottle of water has a mass of 2 kilograms. To convert this mass into grams, we use the fact that 1 kilogram is equal to 1000 grams. Therefore, we perform a simple multiplication:
2 kilograms × 1000 grams/kilogram = 2000 grams.
So, the 2-liter bottle of water has a mass of 2000 grams.

A motorboat takes 40 minutes to travel 20 miles downstream. The return trip takes 60 minutes. What is the speed of the current?
The speed of the current is 5 mph and this can be determined by using the concept of upstream and downstream.
Given :
A motorboat takes 40 minutes to travel 20 miles downstream.
When the boat is going downstream current helps the boat and hinders when the boat is going up.
So, the boat downstream speed is given by:
[tex]\rm s = \dfrac{20}{40}=0.5\;miles \;per\;minute=30\;mph[/tex]
The speed of the boat going upstream is:
[tex]\rm s = \dfrac{20}{60}=\dfrac{1}{3}\;miles \;per\;minute = 20\;mph[/tex]
So, the speed of the current adds when the boat is going downstream and subtracted when the boat is going upstream.
Let the speed of the current be 'c' then:
s + c = 30
s = 30 - c --- (1)
s - c = 20 --- (2)
Substitute the value of 's' inequation (2).
30 - c - c = 20
2c = 10
c = 5 mph
So, the speed of the current is 5 mph.

What is two rules for 4,8,9,18,19
1495÷45 in a long division equation :3
Final answer:
The long division of 1495 divided by 45 results in 33 with a remainder of 10. In the process of division, significant figures are considered, and our answer complies with this rule as both numbers have three significant figures.
Explanation:
To perform the long division of 1495÷45, we divide 1495 by 45 step by step.
Divide the leftmost digit of the dividend, 1, by 45. Since 45 cannot divide into 1, we extend to the next digit, making it 14.Now, determine how many times 45 can fit into 14. It still cannot, so we move to the next digit, now having 149.45 goes into 149 three times (since 45 × 3 = 135), so we put 3 above the line, at the hundreds place.Subtract 135 from 149 to get a remainder of 14 and bring down the next digit from the dividend, which is 5, to make 145.45 goes into 145 three times. So, we put another 3 above the line, at the tens place.Subtract 135 from 145 to get 10, which is the remainder. Since there are no more digits to bring down, we have completed the division.The result of 1495÷45 is 33 with a remainder of 10. Therefore, 1495 divided by 45 is 33 remainder 10.
When considering significant figures in division, it's similar to the example stating that dividing 125 by 307 gives a long decimal, but we limit the precision to that of the least precise number. In this case, since 1495 and 45 both have three significant figures, the result of the division should also be limited to three significant figures, which our result of 33 (with a remainder) naturally complies with.

what is 70.49 divided by 19?
Answer:
3.71
Step-by-step explanation:
We are asked to divide 70.49 by 19.
We know that 19 times 3 is equal to 57 and 19 times 4 is 76, so 19 will go in 70 for 3 times and give a remainder of 13.
9)70.49( 3

Therefore, 70.49 divided by 19 is equal to 3.71.
At a warehouse, the employees can unload 18 trucks in 6 hours. What is the unit rate for unloading trucks?
The unit rate for unloading trucks at the warehouse is 3 trucks per hour, which is calculated by dividing the total number of trucks (18) by the total number of hours (6).
To calculate the unit rate for unloading trucks at the warehouse where employees can unload 18 trucks in 6 hours, we simply divide the total number of trucks by the total hours. This gives us the unit rate of trucks per hour.
Unit rate calculation formula:
Unit Rate = Total Number of Trucks Total Number of Hours
Unit Rate = 18 trucks 6 hours
Unit Rate = 3 trucks per hour
Therefore, the employees at the warehouse have a unit rate of unloading 3 trucks per hour.
(22/7-2/3)÷2 is the value of (22/7-2/3)
To solve (22/7-2/3)÷2, find a common denominator and simplify within the parentheses, then divide the result by 2, giving the answer of approximately 1.2380952381.
To find the value of (22/7-2/3) divided by 2, you first need to calculate the expression within the parenthesis. You can start by finding a common denominator for 22/7 and 2/3, which is 21. Multiplying the numerator and denominator of 22/7 by 3 and 2/3 by 7 gives you
66/21 - 14/21 = 52/21
Now, you divide this result by 2, which is the same as multiplying by 1/2:
52/21 × 1/2 = 52/42 = 1.2380952381
If you use a calculator for the initial division, you have to ensure that you enter the calculation correctly to avoid errors. For example, using the expression 337/217, when calculated, gives you about 1.5529953917.
Proper use of parentheses is important to avoid mistakes like interpreting the expression as (5.7 x 2.8) / (3.1 x 4.2) instead of 5.7 x (2.8 / 3.1) x (1 / 4.2).
