5. A

Answer 2

Answer:

1. [tex]9^{2}[/tex]= 81    2. [tex]10^{3}[/tex] ÷ (5 · 2) + 410 = 510   3. [tex]2^{5}[/tex] · 3    4. 2,040      5. >

Step-by-step explanation:

1. 9 · 9 = 81

2. follow PEMDAS order of operations

5 · 2 = 10

[tex]10^{3}[/tex] = 1000

1000 ÷ 10 = 100

100 + 410 = 510

3. 2 · 2 · 2 · 2 · 2 = 32 · 3 = 96

4. 2040 ÷ 3 = 680 2040 ÷ 5 = 408

5.  the least common factor is: 24

rewriting as equivalent fractions with the LCD:

2/3 = 16/24 5/8 = 15/24

comparing the numerators of the equivalent fractions we have:

2/3           5/8

16/24 > 15/24

therefore comparison shows:

2/3 > 5/8

70 x = this is unswer

Answer:

40 degrees = x

Step-by-step explanation:

As you can see in the picture, there are two lines that indicate that those two lines are equal. So, this triangle is an isosceles triangle, and the base angles of an isosceles triangle are equal. To identify the base angle, check the angles opposite to the side equal. So, we find that 70 is a base angle, so there are two 70 degrees  angles. So,

70 + 70 + x = 180 (The angle sum property of triangles)

=> 140 + x = 180

=> x = 180 - 140

=> x = 40

so that means 4.oo9* 1000 = =49

Consider the figure below.

Answers

Answer: Choice B) 122 degrees

========================================================

Explanation:

First solve for angle c

This angle adds to the 58 degree angle to get 180

c+58 = 180

c = 180-58

c = 122

This is congruent to angle f as well because alternate interior angles are congruent when we have parallel lines like this.

You could also solve 58+b = 180 to follow the same basic path as above. Corresponding angles are congruent when we have parallel lines.

Suppose a rectangular garden plot has a length that can be expressed as x+2 feet and a width expressed as x+7 feet. Write a polynomial expression to represent the area of the garden? Write a polynomial expression to represent the perimeter of the garden?

Answers

Answer:

[tex] Area = x^2 + 9x + 14 [/tex]

[tex] Perimeter = 4x + 18 [/tex]

Step-by-step explanation:

Given:

Length of rectangular garden = (x + 2) ft

Width = (x + 7) ft

Required:

a. Polynomial expression of the area of the garden

b. Polynomial expression of the perimeter of the garden

SOLUTION:

Area of the rectangular garden = length × width

[tex] Area = (x + 2)(x + 7) [/tex]

Expand using the distributive property of multiplication

[tex] Area = x(x + 7) +2(x + 7) [/tex]

[tex] Area = x^2 + 7x + 2x + 14 [/tex]

[tex] Area = x^2 + 9x + 14 [/tex]

Perimeter = 2(length) + 2(width)

[tex] Perimeter = 2(x + 2) + 2(x + 7) [/tex]

[tex] Perimeter = 2x + 4 + 2x + 14 [/tex]

Collect like terms

[tex] Perimeter = 2x + 2x + 4 + 14 [/tex]

[tex] Perimeter = 4x + 18 [/tex]

What is/are the variable(s) is the equation C = 2\pir?

Answers

Answer:

there are 2 variables: C is the dependent variable and r is the independent variable

Step-by-step explanation:

given

C = 2πr

we know that the value of 2π doesn't change (because π = 3.14.. and doesn't change) hence 2π is a constant value.

The only two items in the formula that could possibly change are

C and r

When the value of r changes, it will affect the value of C (i.e the value of C is dependent on the value of x)

Therefore there are 2 variables: C is the dependent variable and r is the independent variable.
