The height of the tree is 30 times the height of the verticle stick.
What are ratio and proportion?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.
A vertical meter stick casts a shadow of 0. 4 meters.
If a tree casts a shadow of 12 meters at the same time.
Let x be the height of the stick and y be the height of the tree. Then we have
y/x = 12/0.4
y/x = 30
y = 30x
The height of the tree is 30 times the height of the verticle stick.

What is the slope of a line that goes through (2,-2) and (5,6)?
Step-by-step explanation:
The slope formula from 2 points is:
m=(y2-y1)/(x2-x1)
So input the numbers:
m = (6 - -2) / (5 - 2)
Solve within parenthesis:
m = (8) / (3)
Then divide!
8/3 = 2 2/3
the slope of the line is 2 and 2/3

A circle is centered at (4, -2) and has a radius of 11.
What is the equation of the circle?
Answer:(x-4)^2+(y+2)^2=121
Step-by-step explanation:
eqaution of circle is this
(x-h)^2+(y-k)^2=r^2
(x-4)^2+(y--2)^2=r^2
and 2 negatives make positive
(x-4)^2+(y+2)^2=r^2
and r^2=121

Let's evaluate ~
[tex]\qquad \sf \dashrightarrow \: 5(z + 4) + 5(2 - z)[/tex]
[tex]\qquad \sf \dashrightarrow \: (5 \cdot z) + (5\cdot4) + (5\cdot2) - (5\cdot z)[/tex]
[tex]\qquad \sf \dashrightarrow \: 5z + 20 + 10 - 5z[/tex]
[tex]\qquad \sf \dashrightarrow \: 5z - 5z+ 20 + 10[/tex]
[tex]\qquad \sf \dashrightarrow \: 30[/tex]
So, the equivalent expression is 30
Answer:
30
Step-by-step explanation:
Let us divide the whole expression by 5. Then we must multiply the whole expression by 5 to obtain the same value as before.
Thus, we get the following expression:
[tex]\implies\huge\text{[}\dfrac{5(z+4)+5(2-z)}{5}\huge\text{]} \times 5[/tex]
[tex]\implies\huge\text{[}\dfrac{(z+4)+(2-z)}{1}\huge\text{]} \times 5[/tex]
Now, open the inner-most parentheses as the expression inside the inner-most parentheses, cannot be simplified further.
[tex]\implies\huge\text{[}\dfrac{z+4+2-z}{1}\huge\text{]} \times 5[/tex]
It should be noted that any number being subtracted from the same number is equivalent to 0. Therefore, we get the following expression:
[tex]\implies\huge\text{[}\dfrac{4+2}{1}\huge\text{]} \times 5[/tex]
Simplify the expression inside the long brackets.
[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5[/tex]
Now, we can open the long brackets and simplify the product of 6/1 and 5.
[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5 = \dfrac{6 \times 5}{1} = \dfrac{30}{1} = 30[/tex]
Therefore, the simplified expression is 30.

1) |x-(-18)| if x<-18
2) |2x| if x<0
3) |x-120| if x<120
The results of the absolute value expressions are:
|x - (-18)| if x < -18 is greater than 0|2x| if x < 0 is greater than 0|x - 120| if x<120 is greater than 0How to solve the absolute value expressionsExpression 1:
We have: |x - (-18)| if x<-18
Open the bracket
|x + 18|
If x < -18, then the values of x are above -18 i.e. -19, -20...
This means that: |x + 18| > 0
Hence, |x - (-18)| if x < -18 is greater than 0
Expression 2:
We have: |2x| if x < 0
If x < 0, then the above equation would be greater than 0
Hence, |2x| if x < 0 is greater than 0
Expression 3:
We have: |x - 120| if x<120
If x < 120, then the values of x are less 120 i.e. 119, 118...
This means that: |x - 120| > 0
Hence, |x - 120| if x<120 is greater than 0
