The center of the circle below is at P. If the central angle < APB measures 88 °, and the length of arc AB = 10 cm., find the radius. (round to the nearest tenth)
If the measure of the arc of the circle is 10 cm. Then the measure of the length of the radius will be 6.51 cm.
What is the relationship between central angle and angle on circumference?Consider an arc of a circle.
Suppose it subtends θ angle on the rest of the part of the circumference (at any point). Then it subtends a 2θ angle on the center of that circle.
we know the formula
Are = θ/360 x 2πr
The center of the circle below is at P. If the central angle ∠APB measures 88° and the length of arc AB = 10 cm.
Then we have
10 = 88 / 360 x 2πr
40.91 = 2πr
r = 6.51 cm

By definition The mode is the most repeated number in the data-set.
Find the surface area of the prism.
10 ft length
1 ft height
5 ft width
Answer:
Surface Area = 130 sq ft
Step-by-step explanation:
If you don't have a picture, draw a picture so you can see what's up. See image. Surface area is the area of all the faces of a 3d shape (a solid) all added up. This solid is a box. It has six faces. Each face is a rectangle. The top and bottom are the same. The front and back are the same. The left and right sides are the same. See image.
Area of a rectangle is:
A = l × w
Area of the top:
5 × 10 = 50
Area of the bottom also 50.
Area of the left side:
1 × 5 = 5
Area of the right side is also 5.
Area of the front:
1 × 10 =10
Area of the back is also 10.
ADD up all 6 areas:
50+50+5+5+10+10
Surface area = 130
Area has square units.
SA = 130 square ft

The sum of two numbers is 27 and their product is 50. Find the numbers.?
Answer:
a + b = 27
=> a = 27 - b
ab = 50
So, (27 - b) x b = 50
27b - b^2 = 50
b^2 - 27b + 50 = 0
Solving, b = 25, 2
Hence,
Case 1: b = 25, a = 2
Case 2, b = 2, a = 25
Answer:
2, 25
Step-by-step explanation:
Let the numbers be x and y :
x + y = 27xy = 50Rearrange the first equation so it is equal to one variable :
y = 27 - xSubstitute the value in the second equation :
x(27 - x) = 5027x - x² = 50x² - 27x + 50 = 0(x - 25)(x - 2) = 0x = 2, 25The wind force f on a sail varies jointly as the area a of the sail and the square of the wind speed w.
the force on a sail with area an area of 500 ft2 is 64. 8 pounds when the wind speed is 18 mph. what
would be the force for a sail with an area of 250 ft? with a wind speed of 35 mph.
how would you solve this problem? what would your answer be?
response:
Answer:
122.5 lbs
Step-by-step explanation:
The relation between force, wind speed, and area can be written ...
f = ks²a
for some wind speed s and area a.
__
The constant of proportionality, k, can be found from the given data.
64.8 = k(18²)(500) . . . force in pounds, area in square feet, speed in mph
k = 64.8/(324×500) = 0.0004
__
Using the equation with the second set of data, we have ...
f = 0.0004(35²)(250) = 122.5 . . . . pounds
The force on the 250 square foot sail would be 122.5 pounds.

The Ferris Wheel rotates in a clockwise
direction
The rider enters on ground level on
the right side of the wheel.

Calculate the rider's total distance
traveled from the moment they get on
at ground level on the right to the
other point on ground level on the left
where they get off.
An example of how to sketch the Ferris Wheel diagram is given in the image attached.
What is the angular speed about?To solve for the angular speed, you can use the formula of"
Given that the diameter is 80 feet, so we know the radius will be 40 feet.
The Ferris wheel bottom is 20 feet high, so we add the radius we get that the middle of the Ferris wheel is 60 feet high.
Finally, the Ferris wheel completes 1 ½ rotation (2π radians) in 1 minutes. So we say that the Ferris wheel is said to spins at π rad/min.
Angular velocity ( 1 ½ rev/1min)( 1min/60 sec)
C = 2π(60)
C ≈ 377.04 feet
540 revolution (1 ½ rotations) is 60 seconds, the speed is then
s = d/t
s = 377.06 ft / 60 sec
s = 6.28 ft/sec
To plot the graph, the final equation will be h(t) = 40sin(πt + π/2) + 60.

Answer:
65
Step-by-step explanation:
Angle FGH = x
Angle FGJ = 25
Angle JGH = 40
Angle FGH = Angle FGJ + Angle JGH
x = 25 + 40
x = 65
The value of x in the diagram is 65.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
From the diagram,
∠JGH = 40
∠FGJ = 25
Now,
∠JGH + ∠FGJ = x
So,
40 + 25 = x
Solve for x.
x = 40 + 25
x = 65

Years at about $405 per month. The total of the payments for the 5-year loan is how much more than the total for the 3-year loan?
Answer:
1,800 more
Step-by-step explanation:
12 × 3 = 36 months
$625 × 36 = $22,500
12 × 5 = 60 months
$405 × 60 = $24,300
$24,300 - $22,500 = $1,800
the interest is paid per month, so we first need to convert the years to months. after that we calculate the total amount of money paid over the specified years. and then we subtract the one from the other to get the difference.
