The number 30 tens is equivalent to three hundred.
In the decimal system, there are ten units in a group called a "ten." Likewise, there are ten tens in a group called a "hundred."
Therefore, one hundred is equal to ten tens.
Since we know that one hundred is equal to ten tens, calculate how many hundreds are equivalent to 30 tens.
Divide 30 by 10 to find out how many groups of ten are present:
= 30 tens ÷ 10
= 3
Therefore, 30 tens are equal to 3 hundreds.

What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Rock and rap songs make 55% of the songs then the rest of the songs should make 45% of the total songs.
Thus we have 45% of 1260=567

The family members going are 4 mothers, 4 grand-mothers and 4 daughters. What will be the minimum number of tickets required?
The minimum number of tickets required for the family members is four because the individuals can be counted in multiple categories—each person can be a daughter, mother, and grandmother.
Explanation:The question is asking for the minimum number of tickets required for a group consisting of 4 mothers, 4 grandmothers, and 4 daughters. To solve this problem, we need to consider how these individuals could be related to each other and overlap in these categories. In a possible scenario, each grandmother is also a mother, and each mother is also a daughter. Therefore, the minimum number of individuals who could cover all these roles is four: one individual who is a daughter, her mother (who is also a daughter to the next in line), her grandmother (who is the mother of the previous person), and her great-grandmother (who fills the role of the fourth grandmother).
To determine the minimum number of tickets required for a group consisting of 4 mothers, 4 grandmothers, and 4 daughters, we have to identify overlapping roles within a three-generation family structure. By recognizing that each person can hold multiple roles, we find that a minimum of 3 tickets is required for this group.
Explanation:The question asks to calculate the minimum number of tickets required for a group including 4 mothers, 4 grandmothers, and 4 daughters. We need to figure out the possible relationships and overlaps in this family structure.
Let's consider a scenario where each grandmother is also a mother, and each mother is also a daughter. This is possible if we are speaking about a family consisting of three generations: the oldest generation (the grandmothers who are also mothers to the middle generation), the middle generation (the mothers who are also daughters to the oldest generation and mothers to the youngest generation), and the youngest generation (the daughters). If we set it up this way, we can have the smallest number of individuals who meet all the necessary conditions.
Here is the step-by-step explanation of the generational setup:
First generation: 1 grandmother who is also a mother.Second generation: Her daughter, who is also a mother.Third generation: Her daughter, who is not a mother.Thus, the three women in this family structure account for all 4 grandmothers, 4 mothers, and 4 daughters. Therefore, the minimum number of tickets required for this group would be 3.

how can you identify a linear nonproportional relationship from a table, a graph, and an equation?
Final answer:
A linear nonproportional relationship can be identified from a table by a consistent change in the dependent variable with a non-zero y-intercept, in a graph as a straight line with a constant slope that does not pass through the origin, and in an equation by the form y = mx + b or y = a + bx with a non-zero y-intercept.
Explanation:
To identify a linear nonproportional relationship from a table, a graph, and an equation, one must understand the characteristics of such a relationship. A linear nonproportional relationship is defined as a relationship where the rate of change between the variables is constant, but the ratio of the dependent variable to the independent variable is not constant.
From a table, a linear nonproportional relationship is identified by a consistent change in the dependent variable as the independent variable changes, but the starting value is not through the origin (0,0); there is a non-zero y-intercept.
In terms of a graph, it would appear as a straight line that does not pass through the origin but has a consistent slope. The slope of the line represents the rate of change, while the point where the line crosses the y-axis represents the y-intercept, which is not zero.
A linear nonproportional equation typically takes the form y = mx + b or y = a + bx, where m or b is the slope and b or a is the y-intercept. To recognize nonproportionality, check if the y-intercept (b or a) is not zero.
One number is 4 less than eleven times another. The sum of the two numbers is 92. Find the numbers.
The problem is an algebraic one involving two linear equations. By setting up correct equations, solving them step-by-step, we find that the two numbers are 8 and 84.
Explanation:This problem falls under algebra and specifically it involves solving linear equations. Let's denote the two unknown numbers as x and y. Given that 'One number is 4 less than eleven times another' we can formulate the first equation like this: y = 11x - 4. The second piece of information given is 'The sum of the two numbers is 92', so the second equation is x + y = 92.
We can substitute y from the first equation to the second equation which gives us: x + 11x - 4 = 92. Simplifying this gives us: 12x - 4 = 92. Solving for x we add 4 to both sides to get 12x = 96, and then divide both sides by 12 to find that x = 8.
Now that we have found x, we can substitute it back to one of the initial equations to find y. Substiting x = 8 into the equation y = 11x - 4 we find that y = 84. So the two numbers we are looking for are 8 and 84.

24.2 / 0.2 can someone explain please?
To calculate 24.2 divided by 0.2, convert the division into a multiplication by recognizing that dividing by 0.2 is the same as multiplying by 5. Thus, 24.2 times 5 gives the result of 121.
To calculate the quotient of 24.2 divided by 0.2, you can follow these steps:
First, recognize that dividing by 0.2 is the same as multiplying by 5. This is because 1 divided by 0.2 equals 5 (since 0.2 is the same as 1/5).Therefore, you can convert the division problem into a multiplication one: 24.2 × 5.Finally, when you multiply 24.2 by 5, you get 121.

A spider traveled 20 feet in 12 minutes. At this rate, how far could it travel in 3 minutes Distance ( ft ) 20 | | | Time (min) 12 | | 3|
The spider's average speed is 5/3 feet per minute, so in 3 minutes it could travel 5 feet.
To solve how far a spider could travel in 3 minutes based on its rate of 20 feet in 12 minutes, we use the concept of proportional relationships. The average speed of the spider can be calculated first.
The average speed is found by dividing the total distance by the total time. So, the spider's average speed is:
20 feet / 12 minutes = 5/3 feet per minute.
To find out how far the spider could travel in 3 minutes at this speed, we multiply the average speed by the time:
(5/3 feet per minute) x 3 minutes = 5 feet.
Thus, the spider could travel 5 feet in 3 minutes at the same rate.

What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Jack was establishing a tree. He needed to dig an opening that was 3 feet deep for every 5 feet of tree height.
The ratio of the length of the tree and the depth of the dig will remain constant.
Let 'd' be the depth of the dig for 17 feet tree. Then the equation is given as,
5 / 3 = 17 / d
d = (17 x 3) / 5
d = 51 / 5
d = 10.2 feet
The profundity of the dig of a tree that is 17 feet high will be 10.20 feet.
