Triangle ABC is a sketch of a triangular flower bed that has an area of 65.1 square feet. Triangle A B C is shown. The length of A B is 13 feet, the length of B C is 10 ft, and the length of A C is b. Angle B C A is 50 degrees. Trigonometric area formula: Area = One-half a b sine (C) To the nearest foot, what amount of fencing is needed to surround the perimeter of the flower bed? 17 feet 33 feet 40 feet 50 feet
Answer:
40 feet
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
The area of triangle ABC is given as:
Area = (1/2) * AC * BC * sin(C)
But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.
Substituting gives:
65.1 = (1/2) * b * 10 * sin(50)
3.83b = 65.1
b = 17 ft
Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10
Perimeter of ΔABC = 40 feet
Answer:
40 feet

In a unit circle, ø=180°. What is the terminal point?
A. (1,0)
B. (0,-1)
C. (0,1)
D. (-1,0)
In a unit circle, θ=180, the terminal point is (-1,0)
The terminal point is (-1, 0) in a unit circle at ø=180°.
What is a circle?
A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 180°
By using the third rule above
Therefore the terminal point is (-1, 0)

A 60-kg robot walks at 1 m/s. What is the robot's kinetic energy?
Answer:
[tex]\boxed {\boxed {\sf 30 \ Joules}}[/tex]
Step-by-step explanation:
Kinetic energy can be found using the following formula:
[tex]KE=\frac{1}{2}mv^2[/tex]
Where m is the mass and v is the velocity.
The robot has a mass of 60 kilograms and a velocity of 1 meter per second.
[tex]m= 60 \ kg \\v= 1 \ m/s[/tex]
Substitute the values into the formula.
[tex]KE=\frac{1}{2} (60 \ kg) (1 \ m/s)^2[/tex]
Solve the exponent first.
(1 m/s)²= 1 m/s * 1 m/s = 1 m²/s²[tex]KE= \frac{1}{2} ( 60 \ kg )(1 m^2/s^2)[/tex]
Multiply the numbers in parentheses.
[tex]KE=\frac{1}{2} ( 60 \ kg*m^2/s^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]KE= 30 \ kg*m^2/s^2[/tex]
1 kg*m²/s² is equal to 1 J Our answer: 30 kg*m²/s² is equal to 30 Joules[tex]KE= 30 \ J[/tex]
The robot's kinetic energy is 30 Joules
I NEED HELP ASAP PLEASEEEE!!!!!
Answer:
Step-by-step explanation:
Use Pythagorean theorem.
Hypotenuse² = base² + altitude²
5) x² = 12² + 6²
= 144 + 36
x² = 180
x = √180
x = 13.42 ft
6) 25² = x² + 19²
625 = x² + 361
625 - 361 = x²
x² = 264
x = √264
x = 16.25 m
7) x² = 7² + 576
= 49 + 576
= 625
x = √625
x = 25 in
8) 2.5² = 2²+ x²
6.25 = 4 + x²
6.25 - 4 = x²
x² = 2.25
x = √2.25

To find the answer to this problem, you can tell first that the entire rhombus is 360 degrees. And PLA is the same as ANP so ANP is 122 degrees.
360 - 122 + 122 = 116
116 divided by 2 = 58
measure LPN is 58 degrees
and half of 58 is 29
so measure LPA is 29 degrees
What is the range of values for the measurement 500 ± 4%
Answer:
well, the first thing you need to do is find 4 percent, which is 5 times as much as 4% of 100, which is 4, 4x5 is 20 so the range of values is 480-520

8)83.33%
10)35%
Step-by-step explanation:
1) write it as a fraction 1/10 = 0.10 multiply by 100 to remove the decimal point you are left with 10 so the answer is 10%
2) write as a fraction 10/20. Simplify 10 divided by 10 =1
20 divided by 10 =2
Write as a fraction 1/2 = 0.50 multiply by 100 to remove decimal point to get 50. So the answer is 50%

Answer: 7.71666667
Step-by-step explanation:
At a pizza restaurant, Mason earns $7.25 per hour to deliver pizzas and $9.00 per hour to make pizzas. One week he earned total of $288.75. During that week he made pizzas for 20 hours. The equation 7.25h + 9(20) = 288.75 could be used to find h, the number of hours he spent delivering pizzas. How many hours that he spent delivering pizzas?
7.25h + 9(20) = 288.75
Multiply 9 by 20:
7.25h + 180 = 288.75
Subtract 180 from both sides:
7.25h = 108.75
Divide both sides by 7.25
h = 108.75 / 7.25
h = 15
He spent 15 hours delivering pizzas.
Answer:
12
Step-by-step explanation:
9x20=180 288.75-180=108.75 108.75÷9=12.0833333333

Helpp!! Determine whether the lines are parallel, perpendicular, or neither. 2x−10y=14 and y=−5x+9. Show work

Answer:
Perpendicular
Step-by-step explanation:
2x-10y=14
-2x -2x
-10y=14-2x
/-10 /-10
y=14+1/5
in order for them to be perpendicular the slope has to be the complete opposite to be more exact the number has to be flipped and so does the sign and since -5 was flipped to +1/5 it shows that they would be perpendicular

The sum of two consecutive integers is 53. What are the two integers?
Equation:
Integers:
Answer:
Equation: 2x+1 = 53 (x is 26)
Integers: 26, 27
Step-by-step explanation:
53 is the sum of 2 consecutive integers. That means one of the integers is one larger than the other. This means that twice one integer plus one equals 53, so the equation becomes x + (x + 1) = 53.
x + (x+1) = 53
Combine x and x to get 2x.
2x + 1 = 53
Subtract 1 from both sides to cancel the +1.
2x = 52
Divide both sides by 2 to undo the multiplication by 2.
x = 26
With this we know the first integer is 26. The second is one more than that, so that's 27. So the two integers here are 26 and 27.

Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
y = -2x-5
Step-by-step explanation:
So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b
To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.
So y=-2x-5.
