Answer:6. -6 is the answer

Step-by-step explanation:add 10 to -10 and -40 and bring down 5x since -10 and 10 cancel out you have to cross it out and have -30 from -40 +10 and now 5x=-30 you have to divide 5 on each side and that would give you -6

In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°. Find the length of o, to the nearest inch.

Answers

Given:

In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°.

To find:

The length of o, to the nearest inch.

Solution:

According to cosine formula,

[tex]a^2=b^2+c^2-2bc\cos A[/tex]

Using cosine formula in ΔOPQ, we get

[tex]o^2=p^2+q^2-2pq\cos O[/tex]

On substituting the values, we get

[tex]o^2=(180)^2+(120)^2-2(180)(120)\cos (171^\circ)[/tex]

[tex]o^2=32400+14400-43200(-0.9877)[/tex]

[tex]o^2=46800+42668.64[/tex]

[tex]o^2=89468.64[/tex]

Taking square root on both sides.

[tex]o=\sqrt{89468.64}[/tex]

[tex]o=299.113[/tex]

[tex]o\approx 299[/tex]

Therefore, the length of o is about 299 inches.

Find the measures of the complementary angles that satisfy each case.
The angles have equal measure.

Answers

Answer:

45 degrees and 45 degrees

Step-by-step explanation:

45+45=90

The measure of the two complementary angles will be 45.

What are complementary angles?

Complementary angles are those whose combined angle is exactly 90 degrees. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that the two angles are complementary to each other.

The complementary angles are the angles having the sum of 45 degrees. The two complementary angles will be calculated as,

45 + 45 = 90

Here one angle is 45 and the other angle is also 45 and the sum of the angles is 90.

Therefore, the measure of the two complementary angles will be 45.

"With patience a ruler may be persuaded, and a soft tongue can

Answers

Answer:

Well rulers don't like to be proven wrong therefore you have to be patient in convincing a ruler that your idea is best. It's pretty much like what inception is in the movie.

A soft tongue is using calm words which in my opinion means you have the utmost confidence in what you're saying. I dont think it literally means bones will break but the person listening will feel as though they are completely wrong if a calm cool person is proving them wrong.

18x+9 = 5x-5 + 105

Combine like terms

18x+9 = 5x +100

Subtract 5x from each side

18x-5x +9 = 5x+100-5x

13x +9 = 100

Subtract 9 from each side

13x +9-9=100-9

13x= 91

Divide by 13

13x/13 = 91/13

y = x2 + 4x + 4
y = 2x + 7

How many solutions?

Answers

Answer:

2 solutions

Step-by-step explanation:

Given the 2 equations

y = x² + 4x + 4 → (1)

y = 2x + 7 → (2)

Substitute y = x² + 4x + 4 into (2)

x² + 4x + 4 = 2x + 7 ( subtract 2x + 7 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Substitute these values into (2) for corresponding values of y

x = - 3 : y = 2(- 3) + 7 = - 6 + 7 = 1 ⇒ (- 3, 1 )

x = 1 : y = 2(1) + 7 = 2 + 7 = 9 ⇒ (1, 9 )

The 2 solutions are (- 3, 1 ) and (1, 9 )

A farmer grows 142 Green pepper plants and 100 a red pepper plants each plant produces about 26 peppers the farmer plans to sell each pepper for three dollars explain to find a reasonable estimate for the total amount of money the Farmer will earn if he sells all of the peppers

Answers

Answer:

$18876

Step-by-step explanation:

Given : 142 green pepper plants & 100 red pepper plants, each plant produces 26 peppers, each pepper sells for $3.

Total Peppers = Total pepper plants x peppers per plant

(142 + 100) x 26  = 242 x 26 = 6292

Total expected money income estimate = Total peppers x price per pepper

= 6292 x 3 = 18876
