Take a look at this expression: 28 + 35.

What do 28 and 35 have in common? Seven is a factor of both of them.

So this means that 28 + 35 = (7 x 4) + (7 x 5).

Now, we bring in the distributive property.

We can take the 7 out of both terms and be left with the 4 and 5.

The answer to 28 + 35 and the answer to 7(4 + 5) is 63. The answer is the same to both. However, you might find that getting to the answer in the second form is easier. So we can use the distributive property to rewrite expressions with common factors to help simplify the work.

WILL GIVE BRAINLIEST! Alice, Bob, and Carrie can all choose a number from 1 to 10 (inclusive).

Viefleur [7K]

Answer:

(a) 720

(b) 180

Step-by-step explanation:

We are given 10 numbers (1,2,3,4,.....,10).

(a) 3 unique numbers are to be chosen by Alice, Bob and Carrie.

Number of ways to choose the 1st number = 10

Number of ways to choose the 2nd number = 9 (1 number chosen earlier can't be chosen again)

Number of ways to choose the 3rd number = 8 (2 numbers chosen earlier can't be chosen again)

Total number of ways of choosing 3 unique numbers = $10 \times 9 \times 8 \Rightarrow 720$

(b)

Number of ways of choosing 1st number = 10 (no restrictions)

Number of ways of choosing 2nd number = 9 (1 number chosen earlier can't be chosen again)

Now, restriction on the 3rd number to be chosen is that one of the two already chosen number should be chosen again.

So, number of ways to choose 3rd number = 2

the number of ways they can choose their numbers if they have to choose exactly two different numbers among all three people =

$10 \times 9 \times 2 \Rightarrow 180$

Hence, the answers are:

(a) 720

(b) 180

A scientist wanted to measure the constant rate of the current in a particular section of the river. She released a tracker into

alukav5142 [94]

Answer:

1.486m/s

Step-by-step explanation:

The rate of change is defined as the change in distance divided by the change in time

Rate = ∆distance/∆time

Distance = 16.5 and 5.5

Time = 10.9 and 3.5

When we put this into the formula above, we have:

Rate of change = 16.5 - 5.5 / 10.9 - 3.5

= 11/7.4

= 1.486m/s

The constant rate of change has been calculated to be equal to 1.486m/s

Top brainilest and extra points

Nataly_w [17]

Answer:

volume of sphere = 288π ft³

Explanation:

volume of sphere = $\frac{4}{3} \pi r^3$

where pi is a constant and r is the radius of the sphere

We are given that:

The diameter of the sphere is 12 ft.

This means that the radius = $\frac{12}{2} = 6 ft$

Substitute with the radius in the above equation to get the volume as follows:

volume = $\frac{4}{3} \pi *(6)^3 = 288\pi$ ft³

Hope this helps :)
