o 5
127+5
127 +25
o via-2572
o Via-532
Answer:
b
Step-by-step explanation:
The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).
What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
We have,
The distance formula can be used to find the distance between two points on a coordinate grid.
The distance between the points (a, 0) and (0, 5) is given by:
√((a - 0)² + (0 - 5)²)
Simplifying the expression gives:
√(a² + 25)
Thus,
The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?
Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15

Answer:
6. 75 Students in Mrs.Reynolds class.
7. 60 Birthdays in February
8. February and May are a combined 20% of birthdays
9. March has 24% of the students birthdays
Step-by-step explanation:
6. Adding all the numbers will give us 75 total students.
7. 450 divided by 7 will get us 6. And there are 10 birthdays in February, so we do 10 times 6 and get 60.
8. On a calculator if you input 20% of 75 you will get 15. February and May are the only 2 birthday months that if you add them up you get 15.
9. If you put 24% of 75 on a calculator you will get 18. March is the only month with 18 birthdays.
There is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Mrs. Reynolds creates a graph of the number of students who have birthdays in the first half of the year.
The graph has been given in the question.
Here y-axis represents Months and the x-axis represents the Number of students
As per the given graph, the required solution would be as:
Adding all of the numbers together generates a total of 75 students.
450 divided by 7 equals 6. And there are ten birthdays in February, so multiply 10 by 6 to get 60.
If you enter 20% of 75 into a calculator, you will obtain 15. February and May are the only two birthday months that total up to 15.
If you multiply 24% of 75 by 18, you get 18. March is the only month in which there are 18 birthdays.
Thus, there is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?
Answer:
1 hour 42 minutes approx
Step-by-step explanation:
Given data
Mayas work rate= 1/4 room per hour
Reginald work rate= 1/3 room per hour
Let the total time taken for both of them be T
Hence their combined work rate
1/4+1/3= 1/T
3+4/12=1/T
7/12=1/T
T= 12/7
T= 1.7 hours
Hence it will take them 1 hour 42 minutes approx
