36÷0.45=80
There are 80 beads altogether

Breaking down the numbers shows that if 45% is 36 beads, then 5% is 4 beads (divide by 9). Then multiply 5% by 20 (to get 100%) and 4 beads by 20 (distributive property) to have 80 beads.

Find f(x) if it is known that f(x+3)=4x+12.

MArishka [77]

Solution:

we are given that

$f(x+3)=4x+12$

we have been asked to find f(x).

we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.

we can re-write the given function as below

$f(x+3)=4(x+3)\\\\\Rightarrow f(x)=4x\\$

Hence the expression representing f(x) is f(x)=4x+3.

$\boxed {d-22 \geq 42}$

*Obs: remember that left at least 42 dollars. In other words, the left over is equal or more than 42 dollars.

2) At the beginning

$d-22 \geq 42 \\ \\ \boxed {d \geq 64}$

28-21=7

thickness = 2x7=14

$volume = \frac{1}{4} \pi \times h( {ro}^{2} - {ri}^{2} ) \\ = \frac{1}{4} \times 3.14 \times 14( {35}^{2} - {21}^{2} ) = 8620.276$
