Answer:

Area is 154 square meters

Step-by-step explanation:

Well lets think about this

If I take a rectangle and cut it into half diagonally I would get 2 triangles right?

So if I have 2 triangles of the same height and base I can make a rectangle

to find the area of a rectangle I do length times width

So lets take our scalene triangle and multiply our base with its width and then divide by 2

22*14 = 308

308/2 is 154

Which of the following could be used to calculate the area of a sector in the circle shown below

lara [203]

Answer:

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Step-by-step explanation:

Given:

Radius = r = 8 in

θ = 42°

To Find:

Area of Sector = ?

Solution:

We know that

$\textrm{Area of Sector}=\pi (Radius)^{2}\times \frac{\theta}{360}$

Substituting the given values in the formula we get

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Which is the required Answer.

Therefore the Last option is correct

$\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})$

Which table represents exponential growth? A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. T

Papessa [141]

Answer:

Table 2

Step-by-step explanation:

We have the tables:

Table 1:

x: 1 2 3 4

y: 2 4 6 8

Table 2:

x: 1 2 3 4

y: 2 4 8 16

Table 3:

x: 1 2 3 4

y: 2 4 7 11

Table 4:

x: 1 2 3 4

y: 2 4 6 10

An exponential growth data set will show a common ratio between y values. Let's look at each of the ratios from each table.

Table 1:

8/6 = 4/3

6/4 = 3/2

Already, we can see that 4/3 ≠ 3/2, which means that this doesn't have a common ratio. So Table 1 is wrong.

Table 2:

16/8 = 2

8/4 = 2

4/2 = 2

The common ratio here is 2, so we know this is correct.

Table 3:

11/7 = 1.57

7/4 = 1.75

Again, we can see that 1/57 ≠ 1.75, so this is wrong.

Table 4:

10/6 = 1.67

6/4 = 1.5

Again, there is no common ratio here, so this is wrong.

The answer is thus Table 2.

Equation: –4x – 5 + 2x = –11

BaLLatris [955]

<h2>ANSWER </h2>

x= 3

Step-by-step explanation:

=> -4x – 5 + 2x = -11

=> -2x = -11+5

=> -2x = -6

=> x= 6/2

=> x= 3
