The first answer is 112 because you multiply 9 by 7 to get 63 and then you multiply 16 by 7 to get 112. and the second one is 27 because 16 times 3 equals 48 so then you multiply 9 by 3 to get 27.:)
This is a ratio problem:
26/18 = 39/x
to solve for x cross multiply: 18 * 39 = 702 and then divide by 26
702 / 26 = 27
x = 27
Answer:
3.56*10^13
Step-by-step explanation:
8.9* 10^4 * 4*10^8
Multiply the number out front and then the exponents
8.9 * 4 * 10^4 * 10^8
When we multiply powers when the bases are the same, we add the exponents
35.6 * 10^(4+8)
35.6 *10^12
But this is not in proper scientific notation. Only one digit before the decimal
Move the decimal one place to the left, that means we need to add 1 to the exponent
3.56 *10^(12+1)
3.56 * 10^13
Answer:
Step-by-step explanation:
It is required to find the value of the missing exponent in the below value i.e.
Let the exponent is x.
Any number can be written in the scientific notation as :
a is a real number
b is any integer
In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.
