There are many toys in a kindergarten. The ratio of the number of dolls to the number of balls to the number of cars is 7:8:5. I
ANEK [815]

Answer:

Number of Dolls = 28.

Number of Balls = 32.

Number of Cars = 20.

Step-by-step explanation:

Given the ratio of the number of dolls to the number of balls to the number of cars is 7 : 8 : 5.

Suppose the highest common factor of the three numbers be 'X'.

Then, Number of Dolls = 7x

Number of Balls = 8x

Number of Cars = 5x

Given the total number of dolls, balls, and cars is 80.

It means 7x + 8x + 5x = 80.

20x = 80

x = 80/20 = 4.

So, Number of Dolls = 7*4 = 28.

Number of Balls = 8*4 = 32.

Number of Cars = 5*4 = 20.

Add or subtract. Write your answer in scientific notation. 6.4 x 10^3+ 1.4 x 10^4+ 7.5 x 10^3
ycow [4]

Answer:

2.79 * 10^4

Step-by-step explanation:

6.4 x 10^3+ 1.4 x 10^4+ 7.5 x 10^3

The exponents need to be the same

6.4 x 10^3+ 14 x 10^3+ 7.5 x 10^3

Add the numbers

6.4 + 14+ 7.5 =27.9

Multiply by the exponent

27.9 * 10 ^3

But this is not in scientific notation

Move the decimal one place to the left and add one to the exponent

2.79 * 10^4
