Answer:

D

Step-by-step explanation:

If you multiply the feet with second you will get their speed

For example:

Moises: 15÷3 = 5 feet per sec

Xavier: 15÷2 = 7,5 feet per sec

-Then, you just need to compare them with the answer, and we have the last answer is D

Find the zeros of the following polynomial.<br> 3x3 + 9x2 - 12x
Arada [10]
x = 4
x = -1
x = 0

Equation at the end of step 1 :

((3 • (x3)) - 32x2) - 12x = 0
Step 2 :

Equation at the end of step 2 :

(3x3 - 32x2) - 12x = 0
Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

3x3 - 9x2 - 12x = 3x • (x2 - 3x - 4)

Trying to factor by splitting the middle term

4.2 Factoring x2 - 3x - 4

The first term is, x2 its coefficient is 1 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -4

Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4

Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .

-4 + 1 = -3 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
x2 - 4x + 1x - 4

Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-4)
Add up the last 2 terms, pulling out common factors :
1 • (x-4)
Step-5 : Add up the four terms of step 4 :
(x+1) • (x-4)
Which is the desired factorization

If a five digit number is rounded to the ten thousands place is it possible for the rounded number to be a six digit number.
Bingel [31]
When rounding a number, the digit of the number can be increased up to 1, but the digit won't be decreased. So, it is possible to round a five digit number into six digit number. But to increase the number digit, the number should be rounded up. To be rounded up, a number should have value 5 or more.

Out of 4,000 colleges surveyed, 60% reported that SAT scores were not used as a high consideration in viewing their applications
Oduvanchick [21]

Answer:

Hi.  

The first thing you want to know is how many schools 60% is.

To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)  

so, 60% of 4,000 = 2,400

To find the number of schools that consider SAT scores:  

Subtract 2,400 from 4,000 which, equals 1,600

              or

Find the remaining percentage; 40%:

4,000 x 0.4 = 1,600

Answer: 1,600 colleges

I hope this helps a little bit.
