A generator runs for 2 1/2 hours and uses 4 3/8 gal of fuel per hour .How many gallons of fuel did the generator use in total? E

uranmaximum [27]

4 3/8 x 2 = 8 6/8
4 3/8 divide 2 = 3/32
6/8 x 4 = 24/32
24/32 + 3/32 = 27/32

In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 t

kramer

Answer:

$\frac{10}{53 \times 46 \times 26}$

Step-by-step explanation:

The probability of matching the number drawn on the gold ball is

$\frac{1}{46}$

The number of possible pairs of numbers from 1 to 53 is

$\binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26$

Choosing 5 numbers, you are choosing 10 different pairs:

$\binom{5}{2} = \frac{5 \times 4}{2} = 10$

Therefore the probability of correctly matching the drawn pair is

$\frac{10}{53 \times 26}$

Thus, the probability of winning (matching the pair AND the gold ball) is

$\frac{10}{53 \times 46 \times 26}$

A Pentagon is transformed according to the rule R0, 180°. Which is another way to state the transformation?

postnew [5]

The another way to state the transformation would be $(x,y)>(-x,-y)$

<u>Solution:</u>

Rotation about the origin at $180^\circ$ : $R_{180^\circ}A \rightarrow O = R_{180^\circ} (x, y) \rightarrow (-x,-y)$

The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to $180^\circ$ about the origin.

So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of $180^\circ$ .

Hence according to the representation, the expression would be $(x, y) \rightarrow (-x, -y)$ .
