Uhm I think you forgot something
B. The perimeter of the plot of flowers
The perimeter measures the distance around all the edges, which is how much rope he'd need
Answer:
Step-by-step explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.
Answer:
C
Step-by-step explanation:
y / 4 = 39 / 30
y / 4 = 1.3
y / 4 * 4 = 1.3 * 4 (What you do to on side you also do to the other)
y = 5.2
So, your answer should be C, 5.2
<u>Answer-</u>
<em>The value of y is 
when x=7 and z=4.</em>
<u>Solution-</u>
As given in the question, y is directly proportional to x, so
-----------------1
And also y is directly proportional to z, so
-----------------2
Combining equation 1 and 2,
Where,
k = proportionality constant
When x=6 and z=1, y=4. Putting theses values,
Now, we have to find the value of y, when x=7 and z=4
Therefore, the value of y is when x=7 and z=4.
