A cube root is the factor that we multiply by itself 3 times to get that number . fourth root is a number that has to be multiplied 4 times by itself same with a fifth root but multiplied 5 times. most numbers have a cube root , 4th root and a fifth root .
In 7 years, the car was 18,000 and after 5 years it is worth 10,500 so if you subtract 18000-10500=7500 and if you do 7500/5=1500 so this means that the car was going down 1500 in value every year.
Answer:
A) ∠9 = ∠10 = ∠11 = ∠12 = 90°
∠2 = ∠3 = ∠5 = ∠8 = 135°
∠1 = ∠4 = ∠6 = ∠7 = 45°
B) 1. ∠4 and ∠1 -> vertical angles
2. ∠7 and ∠5 -> supplementary
3. ∠9 and ∠10 -> supplementary
Step-by-step explanation:
<u>Data</u>
The following are vertical angles, so they are congruent:
∠1 ≅ ∠4
∠3 ≅ ∠2
∠11 ≅ ∠9
∠10 ≅ ∠12
∠7 ≅ ∠6
∠5 ≅ ∠8
From here and data, it is deduced that
∠11 ≅ ∠9 ≅ ∠10 ≅ ∠12
From the picture, the addition of them is equal to 360°, then:
∠11 + ∠9 + ∠10 + ∠12 = 360°
4*∠11 = 360°
∠11 = 360°/4
∠11 = 90° = ∠10 = ∠9 = ∠12
∠2 and ∠4 are supplementary, then:
∠2 + ∠4 = 180°
∠2 = 180° - 45°
∠2 = 135°
∠7 and ∠5 are supplementary, then:
∠7 + ∠5 = 180°
∠7 = 180° - 135°
∠7 = 45°
The estimated number of ramps that can be cut from the board in discuss is; 6 ramps which is a reasonable assumption provided that each ramp is about 2 feet long.
b). The number of ramps that can be cut from the 12 1/2 feet long board is 6 and hence, the length of wood left is; 1/2.
<h3>What is the number of ramps that can be cut from the 12 1/2 feet long board?</h3>
It follows from the task content that skateboard ramps are made from a 12 1/2 feet long ramp.
Consequently, on the assumption that the quantity by measure of length of the board required to make one skateboard ramp is 2 feet, it follows that the estimated number of ramps that can be made from the board is; 12/2 = 6 skateboard ramps.
Ultimately, the amount of wood which is left over upon making the ramps is; 12 1/2 - 12 = 1/2.

Answer:
For x, the equation is 
Step-by-step explanation:
Given: the equation x over 3-5=y
We have to solve for x,
Consider the given equation the equation x over 3-5=y
Here, over means divide, so,
Mathematically written as ,
Solving foor x,
adding 5 both sides, we have,
On solving, we have,
Now, multiply both side by 3, we have,
On simplification, we have,
Thus, for x, the equation is
