Answer:
You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.
"At most" refers to less than or equal to (≤).
This is because "at most" means no more than, must be less than, and can be equal to.
As an inequality, this would be written as x / 3 ≤ 5.
This means that x divided by 3 is less than or equal to (at most) 5.
To solve this, set up a function where w is the number of weeks and h(w) is the number of houses made per week. As you produce 3 houses a week, your function would be h(w)=3w. Now, as you want to produce 54 houses, set your h(w) equal to 54, making your function 54=3w. Now, solve for w, divide both sides by 3, w=54/3=18. This means your answer is 18 weeks.
I will try i had this unit last year, basically the diameter is 5 in this problem, which you multiply by pi (in this case I will use 3.14 as the shortened version since its on-going) which gives you 15.7, then you multiply that by 3 in this problem to get 47.1!
The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
