Find the distance along an ark on the surface of the earth that subtends a central angle of 10 minutes (1 minutes 1/60 degree) The radius of the earth is 3960 miles around to the thousands
Answers
Answer:
11.52 miles
Step-by-step explanation:
We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.
Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles
So L = Ф/360 × 2πR
= (1/6)°/360 × 2π(3960 miles)
= 1/2160 × 7920π
= 3.67π
= 11.52 miles

The angle of a quadrilateral are in the ratio 4:6:3 and it's fourth angle is 100. Find the other three angles of the quadrilateral
Answers
Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
Sum of first 3 angles = 360° - 100° = 260°.
260° / (4 + 6 + 3) = 20°.
First angle = (20°) * 4 = 80°
Second angle = (20°) * 6 = 120°
Third angle = (20°) * 3 = 60°
The angles are 80°, 120° and 60°.
Answer:
Let the angles of the quadrilateral be 4x, 6x, and 3x
Sum of the interior angles of a quadrilateral is 360°.
According to the above problem,
[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]
1st angle=4x=4×20=80°2nd angle=6x=6×20=120°3rd angle=3x=3×20=60°Hence, the other three angles are 80°, 120° and 60°.
It takes five days to repair 1250 meters of road. At this rate, how long will it take to repair 8 km of road?

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of days to repair 8 km be represented as A
Now , the proportion will be
Let the distance be = 1250 meters = 1.250 km
The number of days to repair 1.250 km is = 5 days
Substituting the values in the equation , we get
5 / 1.250 = A / 8
Multiply by 8 on both sides of the equation , we get
A = ( 8 x 5 ) / 1.25
A = 40 / 1.25
A = 32 days
Hence , the number of days is 32 days

A tree is 15 feet tall. A building is 75% taller than the tree. How tall is the building?
a) 27 feet
b) 18.75 feet
c) 16.125 feet
d) 26.25 feet
Answers
Answer:
D
Step-by-step explanation:
The building is 75% taller than the tree (15ft). So you would turn the percent into a decimal, 0.75, and multiply it by 15 to get 11.25. therefore add 11.25 to 15 and get 26.25. Sorry if the explanation isn't up to par
