Are points A, C, D, and F coplanar? Explain.
a) Yes; they all lie on plane P.
b) No; three lie on the same face of the pyramid and the fourth does not.
c) Yes; they all lie on the same face of the pyramid.
d) No; they are not on the same line.
Answers
The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.
The points A, C, D, and F are not coplanar points.
What are the coplanar points?The points that are on the same plane is called coplanar points.
Here, a square pyramid is drawn on a plane.
Points A, C, D are three vertices of a side of the pyramid.
Hence, points A, C, D are coplanar.
However, the point F is the vertex of the opposite side triangle of the square pyramid.
Therefore, the point F is not on the same plane of points A, C, and D.
Hence, points A, C, D, and F are not coplanar.

In the diagram to the right three lines intersect at n.The measure of < GNF is 60, and the measure of < MNL is 47. What is the measure of < HNK?
Answers
< MNL = 47
< MNL and < GNH are vertical angles and are equal
so < GNH = 47
< GNL + < GNH + < HNK = 180....these angles form a straight line...so when added, they equal 180
60 + 47 + < HNK = 180
107 + < HNK = 180
< HNK = 180 - 107
< HNK = 73 <====
Measure of ∠HNK is equals to 73°.
What are linear pair angles?
" Linear angles are formed when the sum of pairs of adjacent angles is equals to 180°."
According to the question,
Measure of ∠GNF = 60°
Measure of ∠MNL = 47°
As per the linear pair angles definition ,
∠GNF, ∠FNM, ∠MNL forms linear pair angles .
Therefore,
∠GNF + ∠FNM + ∠MNL = 180°
Substitute the given values we get,
60° + ∠FNM + 47° = 180°
⇒ ∠FNM = 180° - 107
= 73°
As given three lines intersect at 'N'
∠FNM and ∠HNK are vertically opposite angles and are congruent.
Therefore,
Measure of ∠HNK = 73°
Hence, measure of ∠HNK is equals to 73°.

Nine people come to a party and shake hands with each other. If each person shakes the hand of every other person, how many handshakes occur?
Answers
Final answer:
There will be 36 handshakes among the nine people at the party, as determined by the combination formula 9C2.
Explanation:
Calculating Handshakes
To determine the number of handshakes that occur when nine people shake hands with each other, we can use the concept of combinations. In a handshake situation, the order in which the handshakes occur does not matter; what matters is which two people are shaking hands. Therefore, we can use the formula for combinations without repetition, which is nCk = n! / (k!(n-k)!), where n is the total number of items, and k is the number of items to choose at a time.
In this case, there are 9 people (n=9) and the handshake involves 2 people at a time (k=2). So, the calculation would look like this:
9C2 = 9! / (2!(9-2)!) = 9! / (2!7!) = (9 × 8) / (2 × 1) = 36 handshakes
Therefore, there would be a total of 36 handshakes among nine people at the party.
4.625 as a fraction in simplest form
Answers

4=4 multiply (8/8) = 32/8
so 4.625 = 32/8 add 5/8 equal 37/8
4.625 as a fraction in the simplest form can be written as 37/8.
Given is a decimal number 4.625.
Here the decimal point is 3 units to the left.
So any decimal number can be written as a fraction with powers of 10 as the denominator.
Here since the decimal point is 3 units to the left divide by 1000.
So,
4.625 = 4625 / 1000
Both 4625 and 1000 are multiples of 25.
So this can be written as :
4625 / 1000 = 4625 ÷ 25/ 1000 ÷ 25
= 185 / 40

For stock B, the equation is y=16.04-0.09x where x is the number of hours.
We're trying to find when they will be equal.
15.54+0.11x=16.04-0.09x
1554+11x=1604-9x
1554+20x=1604
20x=50
x=2.5
Final answer: About 2.5 hours
let number of hours = x
1st equation is 15.54+0.11x
2nd equation is 16.14-0.09x
now calulate x so the 2 equations are equal:
15.54+0.11x=16.04-0.09x
mutiply evrything by 100 to get rid of the decimal points andmake the calculations a little easier
1554+11x=1604-9x
add 9 x to both sides:
1554+20x=1604
subtract 1554 from both sides:
20x=50
divide 50 by 20 for x
x=50/20 = 2.5
x = 2.5
so they were the same after 2.5 hours

what is y=-3x+4 and y=3x-2
by using transitive property
Answers
We can flip an equation to have it mean the same thing. Example: x = 5 is the same as 5 = x
The transitive property is the idea where if a = b and b = c, then a = c. Think of it as connecting a chain. Or taking a shortcut. If we know a leads to b, and b leads to c, then we can skip b all together and go from a directly to c.
Same idea applies here: we have -3x+4 equal to y, and y also equal to 3x-2 so -3x+4 = 3x-2
y-(3 times X) + 2=0
3 times X+y-4=0\ -3 times X -4
y= -(3 times X-4
y=4-(3 times X)
2-( 3 times X)- (3 times X)+4=0
y=4-(3 times X)
6-6 times X =0 \-6
-6 times X= -6 \ : -6
X= -6\(-6) X=1
y=4 - (3 times 1)
y=4-3

GCF and Distributive property of 55 + 88
Answers
Final answer:
The GCF of 55 and 88 is 11. Applying the distributive property, 55 + 88 is equal to 143.
Explanation:
The student is asking about the greatest common factor (GCF) and the distributive property of the expression 55 + 88.
To find the GCF, we need to break down the numbers 55 and 88 into their prime factors. The prime factorization of 55 is 5 × 11, and the prime factorization of 88 is 2² × 11. The GCF is the highest common factor between the two prime factorizations, which is 11.
The distributive property states that a × (b + c) = a × b + a × c. Applying this property to the expression 55 + 88, we get 11 × 5 + 11 × 8 = 55 + 88 = 143.
Final answer:
The GCF of 55 and 88 is 11. When we apply the distributive property to 55 and 88, the expression simplifies to 143.
Explanation:
To find the Greatest Common Factor (GCF) of 55 and 88, we can first list the factors of each number:
Factors of 55: 1, 5, 11, 55
Factors of 88: 1, 2, 4, 8, 11, 22, 44, 88
The GCF is the largest factor that both numbers have in common, which in this case is 11.
Now, let's apply the distributive property to the numbers 55 and 88:
55 + 88 = (5 * 11) + (8 * 11)
Using the distributive property, we can simplify this to:
55 + 88 = (5 + 8) * 11
Therefore, the expression 55 + 88 is equal to 13 * 11, which is 143.
