Question 1
In the first question of the Weekly Math Review, we are given a scenario involving a bakery. The bakery is conducting a survey to find out which type of bread is the most popular among its customers. The survey was conducted over a one-week period, and customers were asked to choose their favorite type of bread from a list of options. The bakery recorded the number of votes each type of bread received and provided a bar graph to represent the data.
The bar graph shows five different types of bread: whole wheat, white, rye, multigrain, and sourdough. Each type of bread is represented by a vertical bar, and the height of each bar corresponds to the number of votes it received. From the graph, we can see that sourdough bread received the highest number of votes, followed by multigrain bread. Rye bread received the lowest number of votes.
By analyzing the bar graph, we can easily determine the most and least popular types of bread among the customers of the bakery. However, the question also asks us to find the total number of votes cast in the survey. To do this, we need to add up the number of votes each type of bread received. The answer key for question 1 will provide us with the correct total number of votes.
Question 2
In the second question of the weekly math review, students are asked to solve a word problem involving fractions. The problem states:
John bought a 1/4 pound of cheese for $2. How much would 1 pound of the same cheese cost?
To solve this problem, students need to understand that the cost of the cheese is directly proportional to its weight. They can set up a proportion to find the cost:
1/4 pound / $2 = 1 pound / x
To solve for x, students can cross multiply and then divide:
x = (1 pound * $2) / (1/4 pound) = 8 dollars
Therefore, 1 pound of the same cheese would cost 8 dollars.
In summary, question 2 of the weekly math review asks students to solve a word problem involving fractions and proportions. By setting up a proportion and solving for the unknown variable, they can determine the cost of 1 pound of cheese based on the given information.
Question 3
This question requires us to solve a system of equations using the substitution method. The given system is as follows:
- Equation 1: 2x + 3y = 10
- Equation 2: x – y = 4
To begin, we can solve equation 2 for x in terms of y. We can do this by isolating x on one side of the equation:
x = y + 4
Now that we have an expression for x in terms of y, we can substitute this expression into equation 1. By doing so, we can solve for y:
2(y + 4) + 3y = 10
Simplifying the equation further, we get:
2y + 8 + 3y = 10
5y + 8 = 10
5y = 2
y = 2/5
Now that we have the value of y, we can substitute it back into our expression for x to find its value:
x = (2/5) + 4
x = 22/5
Therefore, the solution to the system of equations is x = 22/5 and y = 2/5.
Question 4
The question 4 of the Weekly Math Review Q2 5 is about a rectangle that has a length of 8 feet and a width of 6 feet. The task is to calculate the perimeter and area of the rectangle.
To solve this problem, we can use the formulas for perimeter and area of a rectangle. The formula for calculating the perimeter of a rectangle is P = 2 * (length + width). In this case, the length is 8 feet and the width is 6 feet, so the perimeter is P = 2 * (8 + 6) = 2 * 14 = 28 feet.
Now let’s move on to calculating the area of the rectangle. The formula for finding the area of a rectangle is A = length * width. Using the given values, the area of the rectangle is A = 8 * 6 = 48 square feet.
So, the perimeter of the rectangle is 28 feet and the area is 48 square feet. These are the final answers to the question 4 of the Weekly Math Review Q2 5.
Question 5
Question 5 of the weekly math review for the second quarter is a multi-step problem involving fractions and percentages. The question asks students to calculate the percentage increase in the population of a city over a five-year period.
Answer:
To solve this problem, students need to first find the difference between the initial population and the final population. This is done by subtracting the initial population from the final population.
Next, students need to divide the difference by the initial population and multiply the result by 100 to find the percentage increase.
The answer key provides the correct calculations and the final answer. Students can use this as a reference to check their work and make sure they have the correct solution.
Overall, question 5 tests students’ understanding of fractions, percentages, and calculations involving population growth. It requires them to apply multiple steps and use mathematical reasoning to arrive at the correct answer.
