I would have each block be 1/6 of a yard

You could technically have any value you want, but for me 1/6 is easiest because 1/2 and 1/3 will scale up to this like so

1/2 = (1/2)*(3/3) = 3/6

1/3 = (1/3)*(2/2) = 2/6

The diagram below might help if you're still stuck on why I picked 1/6.

If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5

Tema [17]

Answer:

$y=-30$

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

$y=kx$

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

$6=k(-1)$

so, we get

$k=-6$

now, we can plug it back

$y=-6x$

now, we can plug x=5

and we get

$y=-6\times 5$

$y=-30$

The price of a cup coffee was 2.40 yesterday. Today, the price fell to 2.15 find the percentage decrease. Round the answer to th

irakobra [83]

ANSWER

The percentage decrease is 10.4%.

EXPLANATION

To calculate percentage decrease, use the formula,

Percentage decrease

$= \frac{new \: price - old \: price}{old \: price} \times 100\%$

Yesterday the price of coffee was 2.40. This is the old price.

Today the price is 2.15. This is the new price.

$= \frac{2.15 - 2.40}{2.40} \times 100\%$

$= \frac{ - 0.25}{2.40} \times 100\%$

$= - 0. 10416667 \times 100\%$

$= - 10.416667\%$

To the nearest tenth, we have:

$- 10.4\%$

Therefore the percentage decrease is 10.4%.
