Is the triangle sum theorem true on the surface sphere? Explain why or why not.
Answer: No, the triangle sum theorem is not true for a sphere surface.
Explanation:
Consider 3 cities A,B,C at the following locations
A is somewhere on the equatorB is at the north poleC is also on the equator such that the curved distance from A to B is exactly 1/4 of the earth's circumferenceThe placement of C is important because this then allows angle ABC to be 90 degrees. Angles BAC and BCA are also 90 degrees each because B is directly north of both A and C (all northerly roads lead to the north pole at point B). This bizarre triangle has all three angles of 90 degrees. The angles here sum to 90+90+90 = 270 degrees.
No, the triangle sum theorem is not true on the surface sphere.
What is the triangle sum theorem?The triangle sum theorem states that, the sum of the three interior angles of any triangle is always 180°.
Given that, is the triangle sum theorem true on the surface sphere or not, so in relation to Euclid's geometry,
A statement that is equivalent to the parallel postulate is that there exists a triangle whose angles add up to 180°. Since spherical geometry violates the parallel postulate, there exists no such triangle on the surface of a sphere. The sum of the angles of a triangle on a sphere is 180°(1 + 4f), where f is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of f, this exceeds 180°.
Hence, there exists no such triangle on the surface of a sphere.

find the equation that passing through the point (4,6) and has a vertex of (2,-3)
Answer:
y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (2, - 3 ) , then
y = a(x - 2)² - 3
To find a substitute (4, 6 ) into the equation
6 = a(4 - 2)² - 3 ( add 3 to both sides )
9 = a(2)² = 4a ( divide both sides by 4 )
[tex]\frac{9}{4}[/tex] = a
y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3 ← in vertex form

OP > NO
OOQ > OP
OP = PQ
Submit Answer
Answer:
I think the answer is OP=PQ
The correct equation will be OP = PQ.
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.
Given that, there is a line segment, OQ, and the point P is the midpoint of the line segment,
We need to determine the relation between OP and PQ,
So, according to the definition of midpoint, the midpoint divides the segment into two equal halves,
Therefore,
OP = PQ
Hence the correct equation will be OP = PQ.

Miranda has $5.05 in dimes and nickel in her car. The number of nickels is seventeen more than the number of dimes. How many of each type of coin does she have?
Answer: 28 Dimes and 45 Nickles
Step-by-step explanation:
See attachment.
Let the number of dimes and nickles be D and N. Use the unit of pennies.
We are told: N = D + 17
The total of 505 cents is the sum of 10D and 5N : 10D + 5N = 505
Use N = (D+17) in the above equation.
10D + 5(D+17) = 505
15D + 85 = 505
15D = 420
D = 28
Since N = D + 17, N = 45
Check:
10D + 5N = 505 ?
10(28) + 5(45) = 505
280 + 225 = 505 It works.

What is the amount received at the end of the period on investing $1000 for 2 years at 5% per annum compound interest?
Answer:
$1102.50
Step-by-step explanation:
The appropriate compound interest formula is
A = P(1 + r)^t, where P is the principal ($1000), t is the number of years, and r is the interest rate as a decimal fraction.
Here A = $1000(1 + 0.05)^2 = $1000(1.05)^2 = $1102.50

The missing length of the given triangle divided into two right-angled triangle is 24.
The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.
Here is the solution in more detail:
The ratio 60:36:x can be written as 2:1:x.
This means that the ratio of the lengths of the three segments is 2:1:x.
The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

All the answers to the various operations given from question 1 to 6 have been explained and answered below.
1) We want to use order of operations to solve;
105 - 7² + (72 ÷ 9)
From order of operations which is BODMAS.
First operation for our given expression is bracket. Thus;
72 ÷ 9 = 8
Thus, we now have;
105 - 7² + 8
Next is addition;
7² + 8 = 57
Thus, we now have;
105 - 57 = 48
2) 884284
- 349407
534877
3) 6 ÷ ²/₇
⇒ 6 × ⁷/₂
⇒ 21
4) Kevin makes $78.37 per day. Thus;
Amount he makes in 7 days = 78.37 × 7
⇒ $548.59
5) Product of 1389 and 6.58
⇒ 1389 × 6.58
⇒ 9139.62
6) We want to use distributive property to express 27 + 60.
Now, in distributive property, it implies that;
a(b + c) = ab + ac
Thus, let us get the greatest common factor of 27 and 60 and factorize it out.
GCF of 27 and 60 is 3. Thus;
27 + 60 = ((3*9) + (3*20))
⇒ 3(9 + 20)
⇒ 3(29)
⇒ 107
