Determine the quantity needed to replace the question mark to make the scale balance The weight times the distance on both sides

Mariana [72]

Solution :

Given

$W_1$ = weight of the first side

= 6 kg = 6000 g

$D_1$ = distance of the first weight from the triangle.

= 3 m = 300 cm

$D_2$ = distance of the first weight from the triangle.

= 600 cm

Let, $W_2$ = weight of the second side

So, $W_1$ x $D_1$ = $W_2$ x $D_2$

or $W_2=\frac{W_1 \times D_1}{D_2}$

$W_2=\frac{6000\times 300}{600}$

= 3000 g

Therefore, the quantity that is used to replace the question mark in order to make the scale balance is 3000 g.

Rashan buys 3 7/10 pounds of flour and Diego buys 2 3/4 pounds of flour they use 4 3/5 pounds of flour to bake bread. how much f

Alex787 [66]

To make this a bit easier we can convert the fractions to decimals, then add them up to find out how much flour they originally had. Rashan bought 3 7/10 pounds of flour, which becomes 3.7 pounds. Diego bought 2 3/4 pounds of flour, which becomes 2.75 pounds of flour. In total they both had 3.7 + 2.75 = 6.45 pounds of flour.

Now they used 4 3/5 pounds to bake some bread, which becomes 4.6 pounds. To find out how much flour they have left, we subtract the 4.6 from 6.45, which equals 1.85 pounds of flour left.

A youth organization collected nickels and dimes for a charity drive. By the end of the 1-day drive, the youth had collected $63

uysha [10]

Let, the numbers of nickels be x.

Given, there were 5 times as many dimes as nickels.

So, the number of dimes = 5x

We know that 1 nickel = $(0.05)

So x nickels = $(0.05x)

Also we know that 1 dime = $(0.1)

So 5x dimes = $(0.1 ×5x) = $(0.5x)

Given total value of dimes and nickels at the end of day 1 is $63.80
