How many 5/8 foot pieces of wood can you cut from a board that is 4 5/8 feet long?

So how many of 5/8 wood pieces out of a 4 5/8 board
let's make the board size into a improper fraction so 8*4+5 = 37
so the board is 37/8
how many times can 5/8 go into 37/8
37/8 / 5/8
"Keep, change, flip" (for division of fractions)
keep the first number, change the sign into multiplication, and flip the last fraction
37/8 * 8/5
That is 7 2/5
Only 7 full 5/8 feet pieces of wood can be cut from a board that is 4 5/8 feet long (remainder 2/5)

Hope this helps :)

klemol [59]

Answer:

$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

Step-by-step explanation:

Given the expression

$\left(-t^4\:-5t^3\:-10t^2\:\right)+\left(9t^3\:+3t^2\:-1\right)$

Remove parentheses: (a)=a

$=-t^4-5t^3-10t^2+9t^3+3t^2-1$

Group like terms

$=-t^4-5t^3+9t^3-10t^2+3t^2-1$

Add similar elements

$=-t^4-5t^3+9t^3-7t^2-1$ ∵ $-10t^2+3t^2=-7t^2$

Add similar elements

$=-t^4+4t^3-7t^2-1$ ∵ $-5t^3+9t^3=4t^3$

Thus, the equivalent expression in simplified form:

$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

Tony’s deposit earned $40.80 in simple over 3 years in an account with an interest rate of 1.7%. How much did Tony deposit?

Vsevolod [243]

Answer:

Tony's deposit was $800.

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=3\ years\\ I=\$40.80\\r=1.7\%=1.7/100=0.017$

substitute in the formula above

$40.80=P(0.017*3)$

$P=40.80/(0.017*3)$

$P=\$800$
