An 18-feet ladder is leaning against the side of a building. The angle between the ladder and the ground is 30°.
How high up on the building, from the ground, is the top of the ladder?

Answers

Answer 1

9514 1404 393

Answer:

  9 feet

Step-by-step explanation:

The sine relation applies.

  Sin = Opposite/Hypotenuse

  sin(30°) = height/(18 ft)

  height = (18 ft)sin(30°) = (18 ft)(1/2)

  height = 9 ft

The ladder extends 9 feet up the side of the building.

Answer: 4 squared + 2 squared is the least, 5 squared is in the middle, 6 squared - 6 is the greatest

Step-by-step explanation:

least in total=20

middle in total=25

greatest in total=30

Step-by-step explanation:

Here,

1st expression:

[tex] {6}^{2} - 6 = 36 - 6 = 30[/tex]

2nd expression:

[tex] {4}^{2} + {2}^{2} = 16 + 4 = 20[/tex]

3rd expression:

[tex] {5}^{2} = 25[/tex]

Hence, the order from least to greatest is,

20 < 25 < 30

Also,

[tex]( {4}^{2} + {2}^{2} ) < {5}^{2} < ( {6}^{2} - 6) \: \: (ans)[/tex]

Help pls I need it now

Answers

Answer and Step-by-step explanation:

So, the format you should choose is the second one.

This is what goes in each box:

[4] (p - [6]) = [12]

The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.

Now, we solve for p.

Divide each side by 4.

p - 6 = 3

Now, add 6 to each side.

p = 9.

Each item cost 9 dollars.

Write numbers in each box to correctly complete the square In Step 3.
Step 3: x^2+ 16x +

Answers

Answer:

Step 3: x² + 6x + 64 = -8 + 64

Step-by-step explanation:

At step 3 add 64 on both sides to complete the square.

so x² + 6x = -8

becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.

continuing from there, we get

x² + 6x + 64 = 56

we then use a² + 2ab + b² = (a + b)² on the left side to get

(x + 8)² = 56 (solve the equation for x)

by taking the root on both sides

√(x + 8)² = √56

x + 8 = +- 2√14 (separate the equations

x + 8 = 2√14

x + 8 = -2√14

Solving for x

x = 2√14 - 8 or x = -2√14 - 8

12x= 180

Step-by-step explanation:

The sum of a triangle always adds up to 180 so,

(4x-1)+ (2x-1) +6 = 180

12x=180

x=15

Answer:

The equation you could use is the 3rd solution. You need to add all of the nubers that have an x after it because you can't add a number that doesn't have x and a number that does have x.  So once you add all of those,  you add the 10, and keep the subtrction symbol instead of the addition symbol. And like I said before, all triangles are equal to 180.

Answers

Answer:

None of the answers provided are equivalent

Step-by-step explanation:

To solve it would be best to simplify each of the expressions you have listed by combining like terms all the x^2 terms have been bolded, the x terms italicized, and the constant terms are underlined

(4x + 1.2) + (2x ^ 2 - 6x + 5) = 2x ^ 2 - 6x + 6.2

(x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) = 2x^2 -2x +7

(4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) = 6x^2 -10x +15

(5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13) = 2x^2 + 2x + 107

Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. How many bags of snack mix did they buy?

Answers

Answer:

6 bags of snack mix

Step-by-step explanation:

x bags of snack mix

y bottles of water

The equations in the question is given as;

20.00 = 2.50x + 1.00y  (i)

11 = x + y (ii)

From eqn (ii);

11 - y = x

substitute the value of x in eqn (i);

20.00 = 2.50(11 - y) + 1.00y

20.00 = 27.5 - 2.50y + 1.00y

20.00  - 27.5  = - 1.50 y

- 7.5 = - 1.50 y

y = - 7.5 / (- 1.5) = 5

Since we are interested in the value of x. Substitute the value of y in eqn (ii);

11 = x + 5

x = 11 - 5 = 6
