Answer:

LCD = 30

3/10 = 9/30

2/3 = 20/30

Step-by-step explanation:

This is the answer because:

1) First, the least common denominator is 30 because 10 x 3 is 30 and 3 x 10 is 30

2) Next, multiply the numerators with the same number you multiplied with the denominator

3 x 3 = 9

2 x 10 = 20

3) Therefore, the answers are:

3/10 = 9/30

2/3 = 20/30

Hope this helps!

In the square below, the two semi-circles are congruent. Find the area of the shaded region. If necessary, round your answer to

Jobisdone [24]

Let's start with the area of the square
$area \: square = s \times s = 8 \times 8 = 64$
now let's subtract the are of the two half circles.
two half circles are the same as one circle, and we know that the diameter of the circle is 8 (same as the side of a square) so it's radius is 8/2= 4 inches

$area \: circle = \pi {r}^{2} = \pi \times {4}^{2} = 16\pi$
now we just subtract and our answer is

$64 - 16\pi = 64 - 16 \times (3.14) = 13.73$

Question 3 (Multiple Choice Worth 1 points)

Evgen [1.6K]

Answer:

$g(x) = x + 6$

Step-by-step explanation:

The parent function is given as:

$f(x) = x + 8$

We want to find a new function that results after shifting f(x), 2 units to the right.

Let that function be g(x), then

$g(x) = f(x - 2)$

We replace x by x-2 in f(x) to get:

$g(x) = x - 2 + 8$

When we simplify, we obtain:

$g(x) = x + 6$

Answer:

The formula is 10 - 3n

Step-by-step explanation:

For an nth term in an arithmetic sequence

U( n ) = a + ( n - 1)d

Where n is the number of terms

a is the first term

d is the common difference

From the sequence above

a = 7

d = 4 - 7 = - 3

The formula for an nth term is

U(n) = 7 + (n - 1)-3

= 7 - 3n + 3

The final answer is

= 10 - 3n

Hope this helps you.
