Find the angle between lines; 0.5880 rad, 33.7°
Answer: 0.5880 rad. 33.7°
<em>Hello there, and thank you for asking your question here on brainly.
<u>Answer: The three different types of angles are an acute angle, which is an angle that is an angle that measures from 1</u></em>° <em><u>to 89°. A right angle, that specifically measures to 90</u></em>°. <em><u>Finally, an obtuse angle that measures from 91° to 179°. An angle that also measures 180° is a straight line, and is called a straight angle.

Answer:
We must add 400 ml of water.
Step-by-step explanation:
We can use the following equation:
Where:
- C(i) is the initial concentration of the solution (80%)
- C(f) is the final concentration of the solution (30%)
- V(i) is the initial volume (150 ml)
- V(f) is the final volume
Now, we just need to solve the equation for V(f).
Therefore, we must add 400 ml of water.
I hope it helps you!
Answer:
c. there is a positive correlation in-between x and y
Step-by-step explanation:
A regression line is a line that suggests that all the points in a scatter diagram lie on or near one particular line. In a simple regression analysis in which y is the dependent variable and x is the independent variable. If the slope is positive, the bivariate data is also said to have a positive correlation. The positive correlation in-between two variables x and y implies that in general, an increase in x goes hand in hand with an increase in y.
I believe its 27 cause u have to multiply 3 times 3 which is 9, then 3 times 9 which is 27
