Marina86 [1]

$\frac{15}{1} \div 2 \frac{1}{2} = \frac{15}{1} \times \frac{2}{5} = \frac{30}{5} = 6$
He filled 6 bags.

•First the whole should be made into a fraction
•If there's a mixed number involved, then it should be converted into a improper fraction
• Using KeepChangeFlip, change the division sign to multiplication sign
•multiply straight across
•if the product is improper, divide the denominator(bottom number) from the numerator(top number)

Find the distance between the points given.<br><br> (3, 4) and (4, 7)

Taya2010 [7]

There is a formula for finding distances using coordinates:

$d=\sqrt{(x_{2}- x_{1})^{2} + (y_{2}-y_{1})^{2} }$

Inserting your variables:

$d=\sqrt{(4- 3)^{2} + (7-4)^{2} }$

$d=\sqrt{(1 + 9)}$

$d=\sqrt{10}$

The answer is $\sqrt{10}$

In 1983 the composition of pennies in the United States was changed due, in part, to the rising cost of copper. Pennies minted a

MA_775_DIABLO [31]

Answer:

<u>Solution for (a)</u>

Earlier Copper pennies are 22.

After 1983 pennies are 28.

Step-by-step explanation:

Pennies minted after 1983 weigh 2.50g

Earlier copper pennies weigh 3.11g

A roll of pennies contains 50 pennies.

A particular roll of pennies weighs 138.42g

Let the number of pennies minted after 1983 be x and;

Earlier copper pennies be 50 - x

2.50x + 3.11(50 - x) = 138.42

Opening the brackets gives;

2.5x + 155.5 - 3.11x = 138.42

Solving like terms together gives;

-0.61x = -17.08

Dividing through gives;

x = 28

So there are 28 after 1983 pennies and;

50 - 28 = 22 earlier pennies.
