Answer:
Step-by-step explanation:
Triangle HIJ is a right angle triangle.
From the given right angle triangle
IJ represents the hypotenuse of the right angle triangle.
With ∠J as the reference angle,
HJ represents the adjacent side of the right angle triangle.
HI represents the opposite side of the right angle triangle.
To determine IJ, we would apply Sine trigonometric ratio. It is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 54 = 7/IJ
0.8090 = 7/IJ
IJ = 7/0.8090
IJ = 8.7 to the nearest tenth
Answer:
242,000
Step-by-step explanation:
Since the 6 in the hundreds place is greater than 5, you round up.
The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 ×

- 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 ×

- 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 ×

is 7999800 times larger than 2 × 10².

Step-by-step explanation:
-3+7= 4
-10-2= -12
4> -12
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
