For the last on you need to set up a proportion with the degrees. You know the arcs add to 360 and that small section is 120 so you set it equal to x over the entire area. X is the answer. The formulas are next to all answers

Manuel bought 9 pounds of apples. He has eaten 1.5 pounds so far and has $15

Artyom0805 [142]

Answer:

$2 per pound

Step-by-step explanation:

Let the cost of apples be x

Then we have equation:

(9 - 1.5)x = 15
7.5x = 15
x = 15/7.5
x = 2

Cost of apple: $2 per pound

Evaluate 2x − 2 for x = 0, x = 1, and x = 2. Question 1 options: A) −1, 0, 2 B) −1, 1, 2 C) 0, 1, 2 D) 1, 2, 4

The value of x in 2^x - 2 when x = 0, x = 1 and x = 2 are -1, 0 and 2 respectively. option A

<h3>Algebra</h3>

2^x - 2

when x = 0

2^x - 2

= 2^0 - 2

= 1 - 2

= -1

when x = 1

2^x - 2

=2^1 - 2

= 2 - 2

= 0

when x = 2

2^x - 2

= 2^2 - 2

= 4 - 2

= 2

Find the greatest common factor of the following monomials: 20a3 and 8a2

dimulka [17.4K]

GCF of given monomials are $4a^2$

Solution:

Given that we have to find the greatest common factor

Given monomials are:

$20a^3 \text{ and } 8a^2$

When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor

Let us first find the GCF of 20 and 8 and then find GCF of variables and then multiply them together

GCF of 20 and 8:

The factors of 8 are: 1, 2, 4, 8

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

$GCF\ of\ a^3 \text{ and } a^2\\\\a^3 = a^2 \times a\\\\a^2 = a^2$
