Answer:
10 centimetre / 5 seconds
Step-by-step explanation:
10 cm / 5 sec means that you are travelling 10 cm every 5 seconds. Or 2 cm every 1 seconds. ( Divide by 5).
10 cm / 20 seconds means that you are travelling 10 cm every 20 seconds. Or 0.5 cm ever 1 second. (Divide by 20)
Answer:
4;
25
Step-by-step explanation:
x² + 2(x)(2) + 2²
x² + 4x + 4
x² - 2(x)(5) + 5²
x² - 10x + 25
I think i need a bit more information but assuming if this is what you are looking for:
to write 50,000 in exponent form look for its multiples other than 1 and itself and then go from there.
This is what i general do, i pick a divisible number and keep dividing till i get to one.
50,000/2 = 25,000
25,000/5 = 5,000
5,000/10 = 500
500/10 = 50
50/10 = 5
5/5 = 1
so i divided by 2, 5,10, 10, 10, and 5 (three 10s, two 5s and one 2)
then i look if these numbers can be written in smaller divisible numbers (i.e. 10 is 2 and 5)
so 2, 5, (2,5), (2,5) ,(2,5), and 5 as you can see that cannot be divided into smaller numbers so we have thus five 5s and four 2s
therefore 50,000 = 5^5 x 2^4
hope this helps :P
(P.S. it is the best way i can explain online without a whole course on this)
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.
Answer:
If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway. So first step:
1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.
2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.
