turn it into months first

147

216

163

206

180

168

add them together, then divide by how many there are

1,080/6=180 months

180/12 =15

Which of the following steps can be performed so that the square root property may easily be applied to 2x2 = 16? (1 point)

Ivan

Answer:

$\Large \boxed{\mathrm{Option \ 2}}$

Step-by-step explanation:

$2x^2 =16$

The square root property requires a quantity squared by itself on one side of the equation. The only quantity squared is x, so divide both sides by 2 before applying the square root property.

The x variable should be isolated on one side of the equation. The x variable is squared so before performing the square root property where we take the square root of both sides, we divide both sides by 2, then take the square root of both sides.

Dividing both sides by 2.

$\displaystyle \frac{2x^2 }{2} =\frac{16}{2}$

$x^2 =8$

Taking the square root of both sides.

$\sqrt{x^2 } =\pm \sqrt{8}$

$x=\pm 2\sqrt{2}$

A=abby's shirts
b=bik's shirts
c=cari's shirts
d=dawn's shirts
e=ellen's shirts

a> everybody
b=2.5c
d=(1/3)c
a+b+c+d=120
e=2d+1
e=13
oook

e=13=2d+1
13=2d+1
12=2d
d=6

d=(1/3)c
6=(1/3)c
18=c

b=2.5c
b=2.5(18)
b=45

a+b+c+d=120
a+45+18+6=120
a+69=120
a=51

14+14*14/14-14 equals what? Explain how you know

Vinvika [58]

Well you use PEMDAS (1. Parentheses 2. Exponents 3. Multiplication and Division in order from left to right 4. Addition and Subtraction in order from left to right) to solve. you have no parentheses or exponents so you do multiplication and division first 14*14 = 196, and 196/14 is 14. Then you do addition and subtraction. 14 + 14 = 28. 28 - 14 = 14.

Answer:

c. 126.27 square feet

Step-by-step explanation:

<u>Area of rhombus is:</u>

A = pq/2, where p and q are diagonals

<u>We have:</u>

p = 18.3 ft
q = 13.8 ft

<u>The area is:</u>

A = 18.3*13.8/2 = 126.27 ft²

Correct choice is C

Use the given figure to solve the remaining parts of the triangle AIR.

PIT_PIT [208]

<u><em>Answer:</em></u>

1. 15.49 cm

2. 14.39 cm

3. 17.32 cm

4. 11.53 cm

5. 5 cm

<u><em>Step-by-step explanation:</em></u>

In the given problem, you can solve the unknown side of the triangle using either<em> Pythagorean Theorem</em> or<em> SOA CAH TOA</em> method.<em> </em><em>In Trigo, you can use the Pythagorean Theorem if the triangle has 90 degrees, or it is a right triangle.</em>

In the given problem, the angle of the triangles are unknown, therefore to solve the unknown side of triangles, we will you use the SOA CAH TOA.

<u><em>In this case, since the given side are b and c, we can use CAH (Cos Teta equals Adjacent over Hypotenuse), and TOA ( Tan Teta equals Opposite over Adjacent)</em></u>

Lets provide the solution for the number, and the rest have the same solutions and process.

b= 17, c= 3, let u is the angle

Cosu= 17/23, to get the angle, use inverse cosine.

The result will be 42.34°, and to get the unknown side, use TOA

Tanu=a/17, a=17Tanu

It will give you 15.49 cm

In the number 2 and 5, it will be the same when you rotate the triangle.
