Answer:

Definition – What is a cubed root? The cubed root of a number is the number that, when multiplied by itself three times (number x number x number), gives the original number. For example, the cubed root of 27 is 3, as 3 x 3 x 3 = 27. The cubed root of 125 is 5, as 5 x 5 x 5 = 125.

Answer:

Infinitely many solutions

Step-by-step explanation:

3x+y=1

15x+5y=5

Step: Solve3x+y=1 for y:

3x + y +−3 x = 1 + −3x (Add -3x to both sides)

y=−3x+1

Step: Substitute−3x+1 for y in 15x+5y=5:

15x+5y=5

15x+5(−3x+1)=5

5=5(Simplify both sides of the equation)

5+−5=5+−5(Add -5 to both sides)

0=0

so there are infinite solutions

Answer:

S =4.9t²

Step-by-step explanation:

Using the equation of motion

S =ut+1/2gt²

u is the initial speed = 0m/s

t is the time

g I the acceleration due to gravity = 9.8m/s²

S is the distance of the object

Substitute

S = 0(t)+1/2 (9.8)t²

S = 0+4.9t²

S = 4.9t²

Hence thee equation that describes the distance an object falls from rest under the influence of gravity is S = 4.9t²

Answer:

$53,500 is the answer.

Step-by-step explanation:

The question is an Arithmetic Progression of common difference (d) = 700

a₁ = $50,000

a₂ = $50,700

d = $700

sixth year can be written as,

a₆ = a + 5d

a₆ = 50,000 + 5 × 700

a₆ = 50,000 + 3,500

a₆ = 53,500

therefore, Alberto will earn $53,500 in his sixth year of employment.

His salery grows by 700 per year, as you can see. This can be represented as [tex]700x+50000[/tex], where 50,000 represents the starting wage, 700 represents the annual increase, and [tex]x[/tex] represents the year (starting from 0). So, if you want to know his wage in his sixth year of employment, simply substitute 5 for [tex]x[/tex]. Note that [tex]x[/tex] is the number of years minus one. As a result, the answer is [tex]700(5)+50000=53500[/tex].

Answer:

1: x = 29

2: Angle C is 93 degrees

Step-by-step explanation:

For 1 angle C has to equal 93 degrees since 52 + 35 = 87 and 180 - 87 = 93, and a triangles interior angles add up to 180 degrees.

From there create an equation: 3(x + 2) = 93 then solve

3x + 6 = 93

-6 from both sides

3x = 87

/3 from both sides

x = 29

For 2 just plug in x (29)

3(29 + 2)

87 + 6

93

Answer: 25

Step-by-step explanation:

Given

The student earned 80% on a math test

The student answered 20 questions

Suppose x is the total no of questions

So, we can write

[tex]\Rightarrow \dfrac{20}{x}\times 100=80\%\\\Rightarrow \dfrac{20}{x}=0.8\\\\\Rightarrow \dfrac{20}{0.8}=x\\\\\Rightarrow x=25[/tex]

So, there are 25 questions in total

Answer:

22√3 units squared

Step-by-step explanation:

1) Draw the trapezoid

2) Notice you have to find the height to find the area of the trapezoid

3) Notice it is a 30 60 90 triangle when you draw the line to find the height

4) Solve for the 30 60 90 triangle and you get the height to be 2√3

5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)

6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)

7) Keep aside the 1/2 for now

8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)

9) Simplify further 44√3

10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3

11) Simplify to get 22√3

12) 22√3 is the area of the trapezoid

13) 22√3 units squared is the final answer

I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.

If you want to know how I solved the 30 60 90 triangle please let me know.

Sorry I was one week late I just saw it today.

Answer:

% increase = 200%

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

b = 73

c = 34

Step-by-step explanation:

<T and <R are equal because they are opposite equal sides.

So b = 73°

Every triangle has 180 degrees

b + c + 73 = 180

73 + c + 73 = 180

146 + c = 180

c = 180 - 146

c = 34
