Answer:
n is 6
Step-by-step explanation:
because sum means addition and if you subtract 9 by 3, you get 6, so we now know that the missing number is 6 because when you add 6 and 3, you get 9. :)
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
The sum of a number n and 3 is 9. Then the equation is given below.
n + 3 = 9
Simplify the equation, then we have
n + 3 = 9
n = 9 - 3
n = 6
The statement in the mathematical form will be n + 3 = 9. And the value of the variable 'n' will be 6.

Step-by-step explanation:
Peggy is laying 60 ft from the base of a tree. The angle of elevation for her to see
the top of the tree is 50º. Use a trigonometric ratio and calculator to find the
height of the tree to the nearest tenth of a foot.
Answer:
The height of the tree is approximately 71.5 feet
Step-by-step explanation:
The given parameters are;
The angle of elevation to see the top pf the tree = 50°
The distance Peggy is laying from the base of the tree = 50 ft.
In order to answer the question using trigonometric ratio, we assume that the angle the tree makes with the ground is 90° that is the tree is perpendicular to the ground
Therefore, the line of sight to the top of the tree, the height of the tree, and the distance from the base of the tree where Peggy is laying, forms a right triangle
Let, 's', represent the line of sight to the top of the tree, let 'h', represent the height of the tree, and let, 'd', represent the distance from the base of the tree where Peggy is laying
The third angle, θ, of the right triangle opposite 'd' is given by angle sum theorem of a triangle as follows;
θ = 180° - 90° - 50° = 40°
θ = 40°
By sine rule we have;
h/sin(50°) = d/(sin θ)
∴ h/sin(50°) = 60 ft./(sin 40°)
h = sin(50°) × 60 ft./(sin 40°) = 71.5052156 ft.
∴ The height of the tree, h ≈ 71.5 ft. by rounding to the nearest tenth

UWV is a 30°-60°-90° triangle.
The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2
The length of the side opposite the 90° angle is 10,
so the length of the side opposite the 30° angle is 5
and the length of the side opposite the 60° angle is 5√3

list multiples of a given whole number.
Answer:
The multiples of a whole number are found by taking the product of any counting number and that whole number. For example, to find the multiples of 3, multiply 3 by 1, 3 by 2, 3 by 3, and so on. To find the multiples of 5, multiply 5 by 1, 5 by 2, 5 by 3, and so on.
Step-by-step explanation:
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
5 × 4 = 20
2 × 1 = 2
2 × 2 = 4
2 × 3 = 6
2 × 4 = 8
2 × 5 = 10 and so on

For each diagram, decide if y is an increase or a decrease of x. Then determine the
percentage.
A
у
B
у
Answer:
A: Decrease, y is 80% of x
B: Increase, y is 160%of x
Step-by-step explanation:
It sounds like it wants to know what percent Y is of X, so if y was 50% of x, that would mean y was half as much of x. so if x was 10 and y was 5
A: x is 5 and y is 4 since y is less it is a decrease. to find the percent do 100*y/x, so in this case that's 100*4/5 =80, so y is 80% of x. and it makes sense it is less than 100% since x is less than y
B: x=5 and y=8 y is greater than x so it is an increase and will be more than 100%. 100*8/5 = 160 so y is 160% of x
