What is 3 equivalent ratios for 3:4

The two facts which could be doubled to obtain the product of 8 and 4 is (4 and 4)

Two facts of a number doubled can be represented as :

• 2 × b = c

The value c here is (8×4) = 32

Substituting the values into the expression and solving for b :

2 × b = c

2 × b = 32

Divide through by 2

b = 32 / 2

b = 16

Hence, two facts that can be doubled is (4 × 4)

2(4 × 4) = 2(16) = 32

Therefore, the two facts which could be doubled are (4 and 4)

Answer:

8,000 in the 8% account

20,000 in the 9% account.

Step-by-step explanation:

x + y = 28000

0.08 x + 0.09 y = 2440

0.08 x + 0.09 (28000 − x) = 2440

0.08 x + 2520 − 0.09 x = 2440

80 = 0.01 x

x = 8000

y = 20000

Answer:

 627

Step-by-step explanation:

We have to find the sum of the given expression which is:

We start adding from right hand digits

we will first add right most digit of 362 and 265

which is 2+5=7

Now, the previous right most digit from both the numbers which is 6+6=12

Now, since, we are getting a two digit number we will consider right digit from the resultant which is 2 and 1 will be taken as carry to the next two digits that are to be added

Now, we will ad next two digits that are left which is 3+2=5 and 1 carry will be added

Hence,6

Final result is written as in sequence they were added which is 627
