Ratio
------------------------------------------------
3 : 1
------------------------------------------------
Find total parts
------------------------------------------------
3 + 1 = 4
------------------------------------------------
Split the 32 according to the parts
------------------------------------------------
4 parts = 32
1 part = 32 ÷ 4
1 part = 8
3 part = 8 x 3 = 24
------------------------------------------------
Split the 32 into the ratio
------------------------------------------------
24 : 8
------------------------------------------------
Answer: 24 : 8

Answer:
The inverse f-1(x) = ( x - 2) / 2.
Step-by-step explanation:
Let 2x + 1 = y
Now find x in terms of y:
2x = y - 1
x = (y - 1) / 2
Replace the x by the inverse f-1(x) and the y by x, so we have:
f-1(x) = ( x - 2) / 2.
Answer:
32 students
Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German
Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)
In this case:
the maximum number of students = 15 + 17 = 32 students
Hope this helps :)
Answer:
B
Step-by-step explanation:
She needed to subtract 36 from both sides of the equation, instead she added 36 to the right side.
Answer:
the exact length of the midsegment of trapezoid JKLM = 
i.e 6.708 units on the graph
Step-by-step explanation:
From the diagram attached below; we can see a graphical representation showing the mid-segment of the trapezoid JKLM. The mid-segment is located at the line parallel to the sides of the trapezoid. However; these mid-segments are X and Y found on the line JK and LM respectively from the graph.
Using the expression for midpoints between two points to determine the exact length of the mid-segment ; we have:
Thus; the exact length of the midsegment of trapezoid JKLM = i.e 6.708 units on the graph
