Answer: $7.98 \times 10^{22}$

Explanation:

30 mins = 0.5 hour

Number of 30 mins in 24 hours = 24 ÷ 0.5 = 48

Number of bacterium = $3^{48} = 7.98 \times 10^{22}$

Answer:

The null hypothesis is: u >= 1300 KN/m^2

And the alternative hypothesis is:

u < 1300 KN/m^2.

Step-by-step explanation:

The null hypothesis describes hat there is no difference or assiciation between variables of a specific population or that it is a particular average value while the alternative hypothesis states otherwise.

In this case study, the null hypothesis is: u >= 1300 KN/m^2

And the alternative hypothesis is:

u < 1300 KN/m^2.

Brainliest if you provide a valid explanation and answer!

Hoochie [10]

Answer:

11cm = diameter.

c=circumference

d=diameter

π=3.14

r=half of diameter

34.56

C=2πr

d=2r

Solving for d (diameter)

d=C

π=34.56

π≈11.00079cm

rounded = 11cm!

Kobe has collected 750 football cards and 660 baseball cards. He wants to divide them into piles so that each pile has only one

Harrizon [31]

Answer: 30 cards

Step-by-step explanation:

To find the greatest possible number of cards in each pile such that there is the same number of cards in each pile we need to find the greatest common factor of 750 and 660.

Using Euclid division method , we have

$750=1(660)+90\\\\660=7(90)+30\\\\90=3(30)+0$

Hence, the greatest common factor of 750 and 660 = 30

Thus, there will be 30 cards in each pile.

Mo is on a baseball team and hears that a ball thrown at a 45-degree angle from the ground will travel the furthest distance. Ho

mixer [17]

Mo must release this ball approximately halfway between straight-ahead and straight-up because the angle subtended must be 45 degrees with the horizontal axis.

<h3>What is distance?</h3>

Distance can be defined as the amount of ground covered (traveled) by a physical object, regardless of its direction, starting point or ending point.

<h3>How should Mo release the ball?</h3>

In order to achieve the furthest travel distance, Mo must release this ball approximately halfway between straight-ahead and straight-up because the angle subtended must be 45 degrees with the horizontal axis, as shown in the image attached below.
