Answer:

$10.5\:mi/h$

Step-by-step explanation:

It was given that Ana bikes for 5.5 hours.

$\Rightarrow t=5.5$

She covers a distance of $57.75\:mi$

$\Rightarrow d=57.75$

We calculate the speed as follows

$Speed=\frac{Distance}{Time\:taken}$

$\Rightarrow Speed=\frac{57.75}{5.5}$

$\Rightarrow Speed=10.5\:mi/h$

The correct answer is D

When asked to write the prime factorization of the number 27 a student wrote 9 . 3. Explain the error and write the correct answ

kondor19780726 [428]

The correct prime factorization of 27 is 3 x 3 x 3

Solution:

Given that,

When asked to write the prime factorization of the number 27 a student wrote 9 . 3

So the student has written,

prime factorization of 27 = 9 . 3

This is wrong

Let us first understand about prime factorization

Prime factorization of a number is any of the prime numbers that can be multiplied to give the original number

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29

Clearly from above list we can see that 9 is not a prime number

So the correct prime factorization of 27 is:

prime factorization of 27 = 3 x 3 x 3

Here "3" is a prime number

A company did a quality check on all the packs of roasted almonds it manufactured. Each pack of roasted almonds is targeted to w

user100 [1]

Answer:

x < 21.01 or x > 21.49 because |x - 21.25| > 0.24

Step-by-step explanation:

We know that each pack of almonds is targeted to weigh 21.25 oz.and a pack must weigh within 0.24 oz of the target weight to be accepted.

Assuming x to be the weight of a given pack of almonds, we can write it as:

$|x-21.25| > 0.24$

Now finding the range of rejected masses (x) of the almonds.

$|x-a| >b$

$-b$

$|x-21.25| >0.24$

$-0.24>(x-21.25)>0.24$

$-0.24>x-21.25$ or $x-21.25>0.24$

$x$ or $x>21.49$

Therefore, the correct answer option is x < 21.01 or x > 21.49 because |x - 21.25| > 0.24.
