Answer:
1) b, c, d
2) d
3) a, c, d
Step-by-step explanation:
Just find the number that can divide by the whole. Say the question was
A pet shop have 20 pets. The same amount of pets are in each room. How many rroms could there be?
If there were 4 rooms, 5 pets would be in each. 20÷4=5. 4 goes into 20 so 4 could be an answer.
If there were 3 rooms, 6 rooms would have 3 pets and 2 would be left over. So it wouldn't work. You just need to find the number that goes into the whole with no remainder.
Answer:
Yes
Step-by-step explanation:
1/8-10(3/4-3/8x)+5/8x
1/8-(30/4-30/8x)+5/8x
1/8-30/4+30/8x+5/8x
Lcm is 8
1-60+30x+5x/8
-59+35x/8
Factorise
-1/8(59-35x)
So when comparing the two,they are observed to be the same
Answer:
9 dimes
Step-by-step explanation:
If she had 18 quarters, that is 2 times the amount of the dimes, that means that if you divide 18 by 2 you would get 9 dimes. Hope this helps:)
Let w = the walking time
the total time is given as 1 hr, therefore (1-w) = running time
Walking dist and running dist is the same
Write a distance equation: dist = speed * time
3w = 9 (1-w)
3w = 9 - 9w
3w + 9w = 9
12w = 9
w = 9/12 = 3/4 hrs walking back
Answer:
The value of the account will be $5,628
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
therefore
The value of the account will be $5,628
