Answer:
6.75 × 10^3
Step-by-step explanation:
Move the decimal 3 times to the left so that the resulting number, m = 6.75, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 3
Write in the scientific notation form, m × 10^n
6.75 × 10^3
Answer:
84°
Step-by-step explanation:
Let the measures of the triangle be 5x, 7x, 3x.
By interior angle sum postulate of a triangle.
5x + 7x + 3x = 180°
15x = 180°
x = 180°/15
x = 12°
7x = 7*12°= 84°
Measure of the largest angle = 84°
Answer:
He must score 83 in the last test.
Step-by-step explanation:
To get a mean of 80 Terry must score a total of 4*80 = 320 over the 4 tests.
So his score for the last test must be 320 - (71 + 80 + 86)
= 320 - 237
= 83.
Answer:
x = 32/3
Step-by-step explanation:
Step 1: Write equation
x/6 = 16/9
Step 2: Solve for <em>x</em>
- Cross multiply: 9x = 96
- Divide both sides by 9: x = 96/9
- Simplify: x = 32/3
Answer:
-75 meters
Step-by-step explanation:
First, subtract 15 from 50, since it is going up:
50 - 15
= 35
Then, add 40, since it is going back down:
35 + 40
= 75
So, the new position is -75 meters relative to sea level
