Answer:
51.15 cm
Step-by-step explanation:
Data provided
Basin = 40 centimeters deep
The Angle between the sloping sides = 77°
The calculation of the shortest distance between the tip of the cone and its rim is shown below:-
The angle will get divided and the angle is as follows
Here In the first triangle, we will follow "Cosine formula" which follows:-
Answer:
From the graph, the slope is -4/5 and the y-intercept is 4 so the slope-intercept equation is y = -4/5x + 4. To convert to standard form we'll do:
y = -4/5x + 4
5y = -4x + 20
4x + 5y = 20
Answer:
19) ( 
)^2 = 
20) -
= -81
21) 
= 16
Step-by-step explanation:
The only wrong ones are
19) ( )^2 =
20) - = -81 ... negative is not inside a parenthesis that's why it is still negative
21) you can add another way is = 16
Everything else looks good. Great job!
Answer:
x= -1/3
Step-by-step explanation:
2x+7x=-3
9x/9= -3/9
x = -1/3
