The shadow of the tree is 40 feet long. A yard-stick placed next to the tree casts a 6 foot shadow. How tall is the tree?
Answer:
pretty sure the tree's 20 feet
According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
We know 1 yard is 3 feet.
Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.
∴ x : 40 : : 3 : 6.
x/40 = 3/6.
6x = 120.
x = 20 feet.

2y-3x=-27
5y+3x=6
Answer:
The answer to the first one is y=3/2x-27/2
The answer to the second one is y=-3/5x+6/5
Step-by-step explanation:
1. 2y-3x=-27
first, you want to add '3x' to both sides.
2y=3x-27
then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.
y=3/2x-27/2
2. 5y+3x=6
First, you want to subtract '3x' from both sides.
5y=-3x+6
Now, you want to divide '5' from both sides.
y=-3/5x+6/5

Solve for the value of the variable: 7x+ 10 = 4x + 16
Enter the answer
Step-by-step explanation:
7x + 10 = 4x + 16
3x + 10 = 16 (subtract 4x on both sides)
3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)
solve for the value of w
Answer:
w = 13
Step-by-step explanation:
Right angle: 90°
Write an equation:
(4w + 5)° + 33° = 90°
Solve for w.
(4w + 5)° = 90° - 33°
(4w + 5)° = 57°
You can take away the brackets.
4w + 5 = 57
Isolate w.
4w = 57 - 5
4w = 52
w = 52 ÷ 4
w = 13
I hope this helps!

11 There are men and women at a meeting.
There are 28 women.
30% of the people at the meeting are men.
Work out the total number of people at the meeting.
Answer:
40 people
Step-by-step explanation:
Step one:
given data
let the total number of persons be x
There are 28 women
The number of men = 30% of x
Step two:
So the total person is given as
30/100*x+28= x
solve for x
0.3x+28= x
collect like terms
x-0.3x= 28
0.7x= 28
divide both sides by 0.7
x= 28/0.7
x= 40 people

5. Use the angle addition formula to find the expression for cos (a+b).
Answer:
Step-by-step explanation:
Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,
Some trigonometric identities are:
tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ
The angle addition formula for cos is given as:
cos(α + β) = cosαcosβ - sinαsinβ
Therefore:
cos(a + b) = cosacosb - sinasinb

Step-by-step explanation:
Case 1 :
[tex]3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\ [/tex]
[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]
Case 2 :

[tex]x = 2 - \frac{2y}{3} \\ x = 2 - \frac{2 \times 1.63}{3} \\ x = 2 - 1.087 \\ x = 0.913[/tex]

Answer:
x = 4
y = 10
Step-by-step explanation:
7x - 3 = 25
7x = 28
x = 4
12y + 35 = 155
12y = 120
y = 10
Hey there!
There are actually a few possible equations, but I will choose these:
FOR X:
7x - 3 = 25
7x = 28
x = 4
FOR Y:
12y + 35 = 155
12y = 120
y = 10
