For b: The answer is $8.0\times 10^{-6}$

For c: The answer is 127.6

For d: The answer is $4.66\times 10^4$

Step-by-step explanation:

Significant figures are defined as the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.
All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.
All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.
All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.
All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.
All zeroes used solely for spacing the decimal point are not significant. For example : 8000 has one significant figure.

Rule applied for the addition and subtraction is:

The least precise number present after the decimal point determines the number of significant figures in the answer.

Rule applied for the multiplication and division is:

The number of significant digits is taken from the value which has least precise significant digits.

For the given options:

Option a: (2.7)(8.632)

The given problem is a multiplication one.

$\Rightarrow (2.7\times 8.632)=23.3$

Here, the least precise significant digits are 2. So, the answer is $2.3\times 10^1$

Option b: (3.600 x 10^-4) / 45

The given problem is a division one.

$\Rightarrow \frac{(3.600\times 10^{-4})}{45}=0.08\times 10^{-4}$

Here, the least precise significant digits are 2. So, the answer is $8.0\times 10^{-6}$

Option c: 2.365 + 125.2

The given problem is an addition one.

$\Rightarrow (2.365+125.2)=127.565$

Here, the least precise significant digits after decimal is 1. So, the answer is 127.6

Option d: (4.753 x 10^4) - (9 x 10^2)

The given problem is a subtraction one.

$\Rightarrow (4.753\times 10^4)-(9\times 10^2)=(4.753\times 10^4)-(0.09\times 10^4)=4.663\times 10^4$

Here, the least precise significant digits after decimal are 2. So, the answer is $4.66\times 10^4$

Find the missing side lengths

sesenic [268]

Answer:

$\sin(45) = \frac{o}{h} \\ 0.7 = \frac{x}{18 \sqrt{2} } \\ 0.7 \times 18 \sqrt{2} = x \\ 0.7 \times 25.45 = x \\ 17.8 = x$

${x}^{2} + {y}^{2} =( 18 \sqrt{2} ) ^{2} \\ {17.8}^{2} + {y}^{2} = 648 \\ 316.84 + {y}^{2} = 648 \\ {y}^{2} = 648 - 316.84 \\ {y}^{2} = 331.16 \\ y = 18.19$
