A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?

Answers

Answer: The number of canned goods in 7th row = 64.

Step-by-step explanation:

The given numbers of canned goods in every row( starting from first ) is represented as

40 , 36, 32, ...

There is a common difference between numbers(d)= 4

∴ Its is an Arithmetic progression.

First term (a) = 40

nth term in A.P. : a(n)= a+(n-1)d

7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64

So, the number of canned goods in 7th row = 64.

Popcorn machine is 3/4 of its height. What's the lengh of the machine

Answers

I'm assuming the length is 3/4 its height and you want an equation so the equation would be Length=3/4height or also L=3/4H and if there was a value for H let us say the number 28 the equation would be L=3/4*28. Three quarters of 28 would be 21 therefore 21=3/4*28.

The braking distance, D, of a car is directly proportional to the square of its speed, v. When d=5, v=10Find d when v=70​

Answers

d \propto v^2

$\implies d=kv^2$

substitute the given values, $5=k(10)^2\implies k=\frac1{20}$

now, $d=\frac{1}{20}\times( 70)^2=\frac{70\times70}{20}=245$
