The correct answer is:  [A]:  " -60 " .
________________________________________________________
Explanation:
________________________________________________________
We are asked to find the "product" of the two numbers, " 12 " and " -5 " .
________________________________________________________
The "product" refers to the result of "multiplying" numbers.
________________________________________________________
So, what is the value, when "12" is multiplied by "-5" ? 
________________________________________________________
<u>Note</u>:  When a "positive number" is multiplied by a "negative number" , the result is a "negative number" . 
________________________________________________________
So;  the product of "12" and "-15" is:  " 12 * -5 " ;   which equals:  " -60 " ; 

which is:  Answer choice:  [A]:  " - 60 " .

A Family travels at a constant rate and drove 420 miles in 7 hours.If they drive at the same speed ,How many miles will they dri
Mazyrski [523]

Answer:

240 miles

Step-by-step explanation:

Step 1

We find the constant rate at which the family travels

Speed(Rate) = Distance/Time

A Family travels at a constant rate and drove 420 miles in 7 hours.

Speed(Rate) = 420 miles/7 hours

= 60 miles per hour

Step 2

If they drive at the same speed ,How many miles will they drive in the next four hours.?

We are to finally calculate the distance for the next 4 hours

Distance = Speed × Time

Speed = 60 miles per hour

Time = 4 hours

Distance = 60 miles per hour × 4 hours

Distance = 240 miles

Therefore, for the next 4 hours the number of miles they would drive is 240 miles

During batting practice, two pop flies are hit from the same location, 2 s apart. The paths are modeled by the equations h = -16
jolli1 [7]
To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can cancel out the -16t^2's to get
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Using this time value, plug into either equation to find the height.
h = 16(2.48)^2 + 56(2.48)
Final answer:
h = 40.4736

Please show how you got your answer to the problem.<br> 4/5 + 3/15 - 2/3 =
natta225 [31]

Answer:

Simplified Answer: 1/3 Non-Simplified Answer: 5/15

Step-by-step explanation:

Make every fraction have a common denominator:

4/5 * 3/3 = 12/15

3/15 = 3/15

2/3 * 5/5 = 10/15

Add and/or Subtract the numerator(s):

12 + 3 = 15

15 - 10 = 5

Place the final numerator over the denominator (Non-simplified Answer):

5/15

Simplify (What can you divide the numerator and the denominator by to make the fraction into it's simplest from without any remainders?):

5 goes into both 5 and 15.

5/15 divided by 5 = 1/3

Simplified Answer:

1/3
