Michael rode his bike 2 2/3 miles on saturday. He rode another 1 5/6 miles on Sunday. How many miles did Michael ride his bike o

svlad2 [7]

To find the miles Michael rode, we can simply add up the miles he rode for both day:

$2 \frac{2}{3} + 1 \frac{5}{6} \\ = \frac{2 + 2 \times 3}{3} + \frac{5 + 6}{6} \\ = \frac{8 \times 2}{3 \times 2} + \frac{11}{6} \\ = \frac{16 + 11}{6} \\ = \frac{27}{6} \\ = 4 \frac{3}{6} \\ = 4 \frac{1}{2}$
Therefore the answer is 4 1/2 miles.

Hope it helps!

alex41 [277]

Answer: Cole and his sister Chloe will take 81 minutes to clean the whole house.

Step-by-step explanation:

Total rooms in the house = 9

Total persons to clean the house = 2 (Cole and his sister Chloe)

Time taken by 1 person to clean one=18 minutes

Time taken by 2 persons to clean one room together=18 divided by 2 = 9 minutes

Time taken by 2 persons to clean 9 rooms (which is the total number of rooms in the house)=9 multiply 9 = 81 minutes

therefore, they will take 81 minutes to clean the whole house.

Find all numbers between 200 and 500 which have exactly 9 factors

MakcuM [25]

Answer:

225, 256, 441, 484

Step-by-step explanation:

Only square numbers can have an odd number of factors, e.g. 4: 1, 2, 4

Therefore only square numbers can have 9 factors.

There are only 8 square numbers between 200 and 500: 225, 256, 289, 324, 361, 400, 441, 484.

One way is to list all the factors of each number and you will find that only 225, 256, 441 and 484 have 9 factors.

The other more efficient way is to acknowledge the fact that if a square number (n x n) has 9 factors, n must have only 4 factors. For example, 225 has 9 factors because it is equal to 15 squared and 15 only has 4 factors: 1, 3, 5, 15.

This way, we can find out that 15, 21 and 22 have exactly 9 factors. However, 256 has 9 factors as well as it is equivalent to 2 to the power of 8. This means that it already has 8 factors: 2, 4, 8, 16...,128, 156. However, we must include 1 as a factor which means it has 9 factors in total as well.

What is the discrimination of the quadratic equation 8x^2-2x-1=0

ELEN [110]

$D=b^2-4ac\\D=(-2)^2-4(8)(-1)\\D=4+32\\D=36$

For another information, when D > 0, there are 2 real roots.

When D = 0, there is only one real root.

And when D < 0, there are no real roots (also known as imaginary.)
