Because if u divide 3 by 4 you get .75 which is out of 100 %
Step-by-step explanation:
<u>Given</u>
- x + 2y = 3 and xy = 2
- show that x³ + 8y³ + 9 = 0
<u>Solution in steps:</u>
- (x + 2y)³ = 3³
- x³ + 3x²(2y) + 3x(2y)² + (2y)³ = 27
- x³ + 6x(xy) + 12y(xy) + 8y³ = 27
- x³ + 8y³ + 6(x + 2y)xy = 27 ⇒ Substitute values
- x³ + 8y³ + 6*3*2 = 27
- x³ + 8y³ + 36 - 27 = 0
- x³ + 8y³ + 9 = 0
Done
Answer:

The answer is 19 - 4, because of PEMDAS.
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Any expression wrapped in parentheses always comes first. Whether the sky is pink or blue, parentheses still come first.
Steps:
1. Do a proportion
X/220=60/100
2. Do 60 times 220 which equals 13,200
3. Do 13,200 divided by 100 which equals 132
4. 132 is how many are carbohydrates
5. Do 220 - 132= 88
6. Your answer is 88
Answer:
A. Intercepted arc.
Step-by-step explanation:
From Geometry we know that arc (
), dimensionless, is measured by the following equation:
(1)
Where:
- Central angle, measured in radians.
- Radius, dimensionless.
If the circle has a radius of 1. Then, we notice that arc is directly proportional to the central angle. Hence, the right answer is A.
