Answer:
Angle 1 is 70 degrees
Angle 3 is 70 degrees
Angle 4 is 110 degrees
Step-by-step explanation: This is right bro. 100%
All these angles r on a flat plane which has a degree of 180
Angle 2 is 110, so u know the other half is 70 degrees.
You can see that the other angle next to angle to is equal to angle 1, so u know Angle 1 equals 70 degrees.
If u flip angle 1 vertically, u can see that it's equal to angle 3, so angle 3 is 70 degrees.
Since angle 3 is 70 degrees, u know that angle 4 has to be 110 degrees.
This is right because if u add angle 3 and 4, u get 180 degrees.
Based on this, 1 horse year equals 3 human years. Therefore, you multiply 16 (the amount of horse years) and 3 to get 48 human years.
Answer: Alex is 15 years
Step-by-step explanation:
Since Alex is w years old and her sister is three years younger than him. The age of his sister will be:
= w - 3.
We will then multiply their ages and equate to 180. This will be:
w × (w - 3) = 180
w² - 3w = 180
w² - 3w - 180 = 0
w² - 15w + 12w - 180 = 0
w(w - 15) + 12(w - 15) = 0
(w + 12)(w - 15)
w - 15 = 0
w = 0 + 15
w = 15 years
Alex is 15 years, her sister is 12 years.
Answer:
y = -4x + 4
Step-by-step explanation:
slope formula: y = mx + b
b is always y intercept which is when the line crosses through the y axis while the x coordinate is at 0. that would make it 4. now we find another point which would be (-1,8)
use change in y/change in x
we already have 2 points
(0,4)
(-1,8)
change in x: -1
change in y: 4
4/-1
slope: -4
The probability is 2/10 because there is 10 fruits in total and 2 bananas
