is 85 units².
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in a ΔABC area of the triangle is (a×b×sinC).
The given triangle has two sides 8 units and 11 units and the angle to the unknown side is 75°.
∴ The area of the triangle is (8×11×sin75°) units².
= 88sin75° units².

What are consecutive integers?Consecutive integers are those numbers that follow each other. They follow in a sequence or in order. For example, a set of natural numbers are consecutive integers.
For example, 4,5,6,7 are consecutive integers. This means that the difference between two consecutive numbers is 1.
If the first number is x, then the second number is (x+1 ) and the third number is (x+3)
The sum of the three number is x +( x+1) + (x+2) = 42
if the second number is x, then the first number is (x-1) and the third number is x+1
Therefore the sum of the three numbers can also be written as (x-1) +x + (x+1) = 42

I graphed both equations online to see what the intersection would be the intersection between both equations is (8,170). I think that this means that in 8 weeks they would both be at 170 dollars, so I think that it will take them 8 weeks to have the same amount of money saved

Sharon began with $42 in her financial balance and added $16 each week. Neil began $70 underwater and kept $30 each week.
Let 'x' be the number of weeks and 'y' be the total amount. Then the equations are given as,
y = 16x + 42 ...1
y = 30x - 70 ...2
From equations 1 and 2, then we have

Answers
Answer:
The second company should get the contract.
Question
The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway.
Reason
Based on the least expensive price per mile per year, the second company should get the contract. This is because the price per mile per year for the second company is lower than the price per mile per year for the first company.
The first company gives a bit of $120,000 per mile and will guarantee the web for eight years. The second company bids the word for $150,000 per mile using a new asphalt material made from used tires.
The second company will guarantee the work for 12 years. Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year.
The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway. The first company gives a bit of $120,000 per mile and will guarantee the web for eight years.
The second company bids the word for $150,000 per mile using a new asphalt material made from used tires. The second company will guarantee the work for 12 years.
Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year
To determine the price per mile per year for each company, we need to divide the total price by the number of years. For the first company, this would be $120,000 / 8 = $15,000 per mile per year. For the second company, it would be $150,000 / 12 = $12,500 per mile per year.
Based on these calculations, the second company offers the least expensive price per mile per year, at $12,500 per mile per year. Therefore, the project manager should choose the second company to receive the contract.

Answer: 1. y = 6

Step-by-step explanation:
1. -2y + 7 = -5
-2y + 7 - 7 = -5 - 7
-2y = -12
y = 6
2.-3(x + 5) = -9
3(x+5) = 9
x+5 = 3
x = 3 - 5
x = -2
3. X+2.5= -7.79
X= -7.79 - 2.50
X = -10.29
4. 3.33 + 2n = -7
3.33 - 3.33 + 2n = -7 - 3.33

2(4–y) – y = 4

8 –3y = 4
–3y=4–8
–3y=–4
y=–4/–3
y= 4/3
since y = 4/3 just substitute for y in eqn (2)
x=4–4/3
multiply both sides by 3

Find the midpoint of the segment with the following endpoints
(5,5) and (1,1)
Answers
The midpoint of the segment given (5,5) and (1,1) is (3, 3).
What is midpoint?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Coordinates of the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂)= [(x₁ + x₂)/2 , (y₁ + y₂)/2].
The midpoint of the line segment with endpoints (5,5) and (1,1)
= [ ( 5 + (1))/2 , ((5) + 1)/2 ]
= [ (6)/2 , 6/2 ]
= [ 3, 3
Therefore, the midpoint of the line segment with endpoints is (3, 3).

In January the depth of a lake wa 943 feet in Augut the depth of the lake wa 754. 4 what i the percentage decreae of the depth of the lake from January to Augut
Answers
19.89% is the percentage decrease of the depth of the lake from January to August.
What is percentage?A quantity or ratio can be expressed as a percentage of 100 by using the word "percentage." Comparing two or more numbers and illustrating how significantly one number differs from the other in proportion to the whole is a popular usage for this technique. If a baseball originally costs $12 and is discounted by 20%, for instance, its new price would be $12 x 20/100 = $2.40 less than the original price. In other words, after the reduction, the ball will cost $12 - $2.40 = $9.60. A percentage may often be determined by dividing a quantity by its entirety and multiplying the result by 100. For instance, if a baseball bat costs $100 and is reduced by 30%, its new cost would be $100 x 30/100, which equates to $30 less.
How to solve?
The depth of the lake decreased by 943 - 754.4 = 188.6 feet from January to August.
The percentage decrease is (188.6 / 943) x 100 = 19.89%

Answer:
a = 13 ftb = 16 ftc = 21 ftA = 39°B = 51°Step-by-step explanation:
You want the complete solution (side lengths and angles) for a right triangle with leg lengths a=13 ft and b=16 ft.
SolutionSince the two leg lengths are given, it is convenient to use the inverse tangent relation to find one of the acute angles.
Tan = Opposite/Adjacent
tan(A) = a/b
A = arctan(13/16) ≈ 39°
B = 90° -A = 51°
The hypotenuse can be found using the Pythagorean theorem, or it can be found using trigonometry. We have just computed angle A, so we can use that value to find the hypotenuse of the triangle.
Cos = Adjacent/Hypotenuse
Hypotenuse = Adjacent/Cos
c = b/cos(A) = 16/cos(39.093859°) ≈ 21 . . . . feet
Then the solution is ...
a = 13 ftb = 16 ftc = 21 ftA = 39°B = 51°__
Additional comment
Note the calculator is set to DEG mode so the angles are reported in degrees.
The hypotenuse is found using the original full-precision value of the angle, not the rounded value required to answer the problem statement.

The value of the angles of the given quadrilateral are;
8) ∠X = 124° = ∠W
∠Y = 56° = ∠Z
9) ∠J = 44° = ∠K
∠L = 136° = ∠M
How to find the angles of a quadrilateral?The sum of angles of a quadrilateral is equal to 180 degrees. Now, in the quadrilateral given, the two angles on the slant side always equal 180 degrees. Thus;
8) From the given trapezium, we can use the definition above to say that;
∠X + ∠Y = 180°
Thus;
(13x - 7)° + (8x - 2)° = 180°
21x - 9 = 180
21x = 189
x = 189/21
x = 9
Thus;
∠X = (13(9) - 7)°
∠X = 124° = ∠W
∠Y = 180° - 124°
∠Y = 56° = ∠Z
9) From the above, we can apply the same to this quadrilateral to get;
7x + 2 + 25x - 14 = 180
32x - 12 = 180
32x = 180 + 12
32x = 192
x = 192/32
x = 6
∠J = (7(6) + 2)
∠J = 44° = ∠K
∠L = 180 - 44
∠L = 136° = ∠M
