Answer:

V(a) = 3,750mm^3

Step-by-step explanation:

for mathematically similar figures scale factor (sf) is common

that is if their lengths ratio is 3

then their areas ratio will be 3^2

volume's ratio will be 3^3

So here in this problem we have Surface Areas

by that we will find sf^2

SA(b) / SA(a) = 10478 / 1550 = 6.76

sf^2 = 6.76

sf = 2.6

now volumes ratio will be

V(b) = sf^3 * V(a)

= 2.6^3 * V(a)

= 17.576 * V(a)

Substitute this in the Volume equation given

V(b) - V(a) = 62160

=> 17.576 * V(a) - V(a) = 62160

=>16.576 * V(a) = 62160

=> V(a) = 62160 / 16.576

=> V(a) = 3,750

Let “a” represent Andrew’s age TODAY. Write an expression to represent the situation. Five years less than four times Andrew’s a

EleoNora [17]

Answer:

$y = 4a - 5$

Step-by-step explanation:

Let y represent the given situation.

Given:

Andrew's age = a

We need to find the expression for given abatement.

Solution:

The given statement: Five years less than four times Andrew’s age

Five years less than four times Andrew’s age = $4\times (Andrew's\ age) - 5$

Andrew's age is known, so we substitute Andrew's age = a

$y = 4\times (a) - 5$

$y = 4a - 5$

Therefore, the expression for the given situation $y = 4a - 5$
