The number of additional sandwiches is 15.
If we multiply 75 sandwiches by 0.2 (20%), then we get 15, which would be the number of sandwiches needed to be sold to meet the sales goal.
Hope this helped.
Answer:
m=243/4 when v=9.
Step-by-step explanation:
We know that when y varies directly with x², the formula of direct proportion is
where 'k' is the constant of variation.
so
As m varies directly with v², and m=3 when v=2
m=kv²
k=m/v²
= 3/(2)²
=3/4
Hence, k=3/4
so when v=9 then the expression becomes
m=kv²
substituting v=9 and k=3/4
m= 3/4(9)²
=3/4 × 81
=243/4
Therefore, m=243/4 when v=9.
4) They are congruent by ASA.
5) you can set up a proportion.
original height / shadow = original of tree/ shadow of tree
18/21 = x/14
21x = 252
x = 12
SO the height of the tree is 12
