2.90 degrees

3.Medians

Step-by-step explanation:

We are given that

1.Segment GB is a median of triangle ABC.

AG=10 units

We have to find the measure of segment GC.

We know that median divides the opposite side of triangle into two equal halves.

Therefore, AG=GC=10 units

2.We are given that segment BD is an altitude of triangle ABC.

We know that altitude BD is perpendicular to side AC.

Therefore, $\angle BDC=90^{\circ}$

3.Centroid: It is the intersection point of medians where three medians of triangle meet .

Answer:Medians

Answer:

Step-by-step explanation:

To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.

It depends on the results but for EX: The older you are there better grades you get or there is no relation(meaning that your age does not affect your grades)

Exams are approaching and Helen is allocating time to studying for exams. She feels that with the appropriate amount of studying

svp [43]

Answer: 0.05

Step-by-step explanation:

Let M = Event of getting an A in Marketing class.

S = Event of getting an A in Spanish class,

i.e. P(M) = 0.80 , P(S) = 0.60 and P(M∩S)=0.45

Required probability = P(neither M nor S)

= P(M'∩S')

= P(M∪S)' [∵P(A'∩B')=P(A∪B)']

=1- P(M∪S) [∵P(A')=1-P(A)]

= 1- (P(M)+P(S)- P(M∩S)) [∵P(A∪B)=P(A)+P(B)-P(A∩B)]

= 1- (0.80+0.60-0.45)

= 1- 0.95

= 0.05

hence, the probability that Helen does not get an A in either class= 0.05

Justin buys 12 pencils for $0.56. He pays with a $10 bill. How much charge will he recieve?

Andreyy89

I don't imagine you could divide with this since the answer would lead to 0.04 but if so i'm an idiot.

The way i would do it is 12 x 0.56 which makes 6.72. (it just makes sense?)

So for the 0.04 he would get back 9.96

The 6.72 he would get back 3.28

Sorry i considered the possibilities.

The equation is $155p+225f=5050$ .

If p = 17, f = 13. This value is a reasonable value in this context.

If f = 28, p = -10. This value is not reasonable in this context.

Step-by-step explanation:

Step 1:

$155p+225f=5050$ ,

where p is the part-time memberships and f is the number of full-time memberships.

Kiri needs to make $5,050 a month from this rented space.

Each part-time membership costs $155 and each full-time membership costs $225.

Step 2:

We need to calculate the value of f when p = 17,

Substituting the value, p = 17 in the equation, we get;

$125(17)+225f=5050$ , $225f=5050-125(17),$

$225f=2925, f = \frac{2925}{225}, f =13.$

The value of f = 13 and p = 17. This is a reasonable value in this context.

Step 3:

We need to calculate the value of p when f = 28,

Substituting the value, f = 28 in the equation, we get;

$125p+225(28)=5050$ , $125p=5050-225(28)$

$125p=-1250, p = \frac{-1250}{125}, p=-10.$

The value of f = 28 and p = -10. This is not a reasonable value in this context. as the values of f and p cannot be negative for this given equation.
