Answer: GCF = 14

Step-by-step explanation:

The factors of all numbers:

14 - 2, 7, 14

28 - 2, 4, 7, 14, 28

42 - 2, 7, 14

As you can see, 14 is our GCF.

Chin-li is building a brick wall along the front of his property. The wall will have 15 rows of bricks, with 32 bricks in each r

Finger [1]

Answer:

<h3>The solution is 480 bricks.</h3>

Step-by-step explanation:

We are given that number of rows of bricks in a wall = 15 rows.

Number of bricks in a row = 32 bricks.

In order to find the total number of bricks, we need to multiply number of rows with number of bricks in a row.

Total number of bricks in 15 rows = 15 × 32 = 480 bricks.

Therefore, will Chin-li will need 480 bricks.

<h3>The solution is 480 bricks.</h3>

a teacher plans a simulation to estimate the probability that a student will pick a vowel out of a bag of 26 tiles, each with a

Alex Ar [27]

Answer:

Yes

Step-by-step explanation:

Given that a teacher prepares 26 tiles with 5 vowels numbered 1 and 21 consonants numbered 2.

The probability for drawing vowel = $\frac{5}{26}$

Prob for consonant = $\frac{21}{26}$

If number of trials is atleast 30 we can expect reliable results.

Here the results are recorded for 120 times at random.

Since number of trials is large, we can expect a reliable and accurate results representing the actual probability.

This is because more the number of trials, the less would be the margin of error i.edeviationfrom the expected probability would be minimum

One brand of coffee is packaged in cylinders where the height is equal to the radius, r. The volume of the package, in cubic cen

aliya0001 [1]

Answer:

Step-by-step explanation:

This problem is a composition of function defined by C(V(r)), now we have the functions $V(r)= \pi r^{3}$ and $C(V)=3.2V$ , where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,

$C(V(r))=3.2(\pi r^{3} )$

Therefore, the right answer is the last choice.
