Answer:

2/13

Step-by-step explanation:

In a deck of 52 cards, there are 2 sets of red cards. Diamonds and Hearts. In each set of red cards, there are 4 fives. If there are 2 sets, that means that there are 8 red fives in the deck of 52 cards. This means that the probability is 8/52 which is simplified into 2/13.

You have a new 10-day workout routine. You want to do 10 sets of 10 sit-ups each
Sholpan [36]

Answer:

10²

Step-by-step explanation:

Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through <em>exponents</em>. Since we have 2 10's multiplied together, we can rewrite our expression as 10².

Answer:

7.76\times 10^6\ \text{inches}

Step-by-step explanation:

We know that,

1\ \text{inch}=1.578 \times 10^{-5}\ \text{miles}

We need to convert 1225 miles to inches. It can be done as follows :

1\ \text{mile}=\dfrac{1}{1.578 \times 10^{-5}}\ \text{inches}\\\\1225\ \text{miles}=\dfrac{1225}{1.578 \times 10^{-5}}\ \text{inches}\\\\=7.76\times 10^6\ \text{inches}

So, there are 7.76\times 10^6\ \text{inches} in 1225 miles.
