2 wide walls (15x6)x2=180 square feet
2 long walls (25x6)x2=300 square feet
ground 25x15=375 square feet
sum them all up and you get
375+300+180=855
you need paint for 855 square feet
Answer: Three less than a number

<em>An unknown quantity less than three. would be 3 - z or z < 3</em>
Answer:
17 boys and 11 girls
Step-by-step explanation:
Create a system of equations where b is the number of boys and g is the number of girls:
b + g = 28
b = g + 6
Solve by substitution, by substituting the second equation into the first one:
b + g = 28
(g + 6) + g = 28
2g + 6 = 28
2g = 22
g = 11
So, there are 11 girls.
Since there are 6 more boys than girls, there are 17 boys.
So, there are 17 boys and 11 girls in the class.
15 girls 12 boys 5x3=15 and 4x3=12 so 15 girls 12 boys
Answer: 2, 2, 3
Frequency refers to the number of times an event or value occurs, and in this case, the frequency of the Temperature is the amount of times a number appears in the data.
A grouped frequency table is a frequency table with data organised into smaller groups, often referred to as sets or classes. They can be very useful when we are working with large data sets.
From 101-106 the frequency is 2, because in the data, 104 and 104 fits into the class
From 107-112, the answer is 2, because in the data box to the left, there are two numbers ( 112, 107) that fit into class
From 113-118, you should write the frequency as 3, because the numbers to the left ( 114, 117, 118) fit into the data set.
I hope I explained everything you don't understand! :)
