Answer:
Here you go.
Step-by-step explanation:
x=25cos10+30cos100
y=25sin10+30sin100
v=√(x^2+y^2)
α=tan(y/x)
Rounding to two decimal places in intermediate steps...
x≈19.41, y≈33.89
v≈39.05
α=60.20°
So (39.05, 60.20°)

QUESTION 45
What is the value of x?
3x
Answer:
1/67
Step-by-step explanation:
Complete question
If X+2/3x is equal to 45. find the value of x
Given the equation
x+2/3x = 45
Cross multiply
x+2 = 3x(45)
x+2 = 135x
x - 135x = -2
-134x = -2
x = 2/134
x = 1/67
Hence the value of x is 1/67

Answer:
Area of the circle = 572.3 square ft.
Step-by-step explanation:
Area of a circle is given by the formula,
Area of a circle = πr²
Here 'r' = Radius of the circle
Diameter of circle given in the picture = 27 ft
Radius of the circle = [tex]\frac{27}{2}[/tex]
= 13.5 ft
Area of the circle = π(13.5)²
= 3.14(13.5)²
= 572.265
≈ 572.3 square ft

Is it possible to draw a quadrilateral that is not a rectangle, but has at least one right angle.Explain
Answer:
Yes
Step-by-step explanation:
A trapezoid with two right angles is a quadrilateral with two right angles.
Rico and Darla each measured a side and height on the triangle below to find its area.
Rico’s side measured 7.5 m and Darla’s side measured 9 m.
Choose True or False for each statement.
A triangle with two base and side length measurements. One side length is nine meters, and the height from that side is five meters. The other side length is seven and five-tenths meters and the height from that side is six meters.
Darla can use either the height of 6 meters or the height of 5 meters to find the area of the triangle.
Choose...
If Darla uses the height of 6 meters and Rico uses the height of 5 meters, they will find the same area of the triangle.

Answer: not sure
Step-by-step explanation:
Choose ALL the lines PARALLEL to the following line: y = 2/9x - 7
y = 9/2x-12
y = 2/9x + 8
-2y = 9x + 8
9y = 2x -18
Answer: y = 2/9x + 8 and -2y = 9x + 8
Step-by-step explanation: Hope this help :D
Parallel lines have the same slope so y = 2/9x + 8 and 9y = 2x -18 will be parallel to the line y = 2/9x - 7 so option (B) and (D) will be correct.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
The equation of a linear line is given by
y = mx + x where m is slope
So,
y = 2/9x - 7 have slope as 2/9
Now since parallel lines have the slope same so all lines whose slope matches with 2/9 will be parallel to this.
So,
y = 2/9x + 8 has slope of 2/9
9y = 2x -18 ⇒ y = 2/9 x - 2 has slope of 2/9
Hence "y = 2/9x + 8 and 9y = 2x -18 will be parallel to the line y = 2/9x - 7"

A restaurant used 231 eggs last week. 46 of them are colored white, w. The remaining eggs are colored brown. Write an equation that represents the situation. ( i will give you brainly)
Answer:
46 + W = 231
Step-by-step explanation:
Answer:
My guess: 231 = 46 + b
Step-by-step explanation: Because they didn't mention how many were colored brown, we would use a variable to represent them, in this case I use b. But we do know 46 of them were white. so the equation would simply be 231 = 46 + b. After you add 46 and b you will get the total to 231. You can find b from subtracting 231 to 46. Then add b to 46 and get the total of 231

Three cylinders have a height of 8cm. Cylinder 1 has a radius of 1cm. Cylinder 2 has a radius of 2cm. Cylinder 3 has a radius of 3cm. Find the volume of each cylinder.
Answer:
Volume of Cylinder 1 = π×r×r×h
= 22÷7×1×1×8
= 25.13cm
Volume of Cylinder 1 = π×r×r×h
= 22÷7×2×2×8
= 100.53cm
Volume of Cylinder 1 = π×r×r×h
= 22÷7×3×3×8
= 226.19cm

The adjacent side is the side that makes up the angle but is not the hypotenuse.

11. A bag contains 2 blue marbles and 2 green marbles. What is the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble?
Please show work ty
Answer: your answer should be 50%
Step-by-step explanation: This is because there are only four marbles in the bag total and only 2 are blue and only 2 are green so your chances of pulling out either is 50%
Answer:
33%
Step-by-step explanation:
2 blue marbles + 2 green marbles = 4 marbles
1st draw for blue: 2/4 (2 blue marbles out of 4 marbles)
2nd draw for green: 2/3 (1 less marble from 4, marble not put back in)
2/4 x 2/3 = 4/12 = 1/3 = 0.33 or 33%
